A system and method for pushing information from a hoe. system ,0 a mobile data 
communication de.ce upon sensing a triggering even, is provided. A redirect program 
operating at the host system enab.es a user to continuous* redireo. certain nser-se.ec.e4 data 
items from the host system to me user's mobUe data communication device open detecting that 
one or more user-defined triggering even* has occurred. The redirect program operates in

configure and detect a particuhu user-defined even,, and dren to repackage the user-se.ected data 
items in an e,ectronic wrapper prior to pnahing me data items to the mobile device. 

Using me redirect program, the user can select certain da* items for redirection, such 
as E-mail merges, c.lend» events, meeting notifications, address entires, jooma! entriea, 
S pe^onal reminders etc. Having selected the data items for redirection, the nser can then 
S configure one or more even, triggers to be sensed by the redirect program, which flren initiates 
redirection of me user data items upon sensing on. or more of.be even, triggers. These user- 
defined trigger points (or even, trigger) may be externa, events, internal even* or networked 
3 even*. Once an even, haa triggered redirection of the user da«a items, the boa. sya«em men

system. 

The rediteetor ptogmm also provides a set of sonware-imp.emen.ed control functions for 
determining the We of mobile data communication device and its address, for programming a 
preferred lis, of message types that are ,0 be redirected, and for dehsmining whether me mobile 
device can receive and proceas certain types of message atiachments, such as word processor or

voice attachments. The mobil?device control functions are initially set bylne user of the mobile 
device at the host system. These functions can then be altered on a global or per message basis 
by transmitting a command message from the mobile device to the host system. 

In an alternative embodiment, the redirector program executes on a network server, and 
the server is programmed to detect numerous redirection event triggers over the network from 
multiple user desktop computers coupled to the server via a local-area-network ("LAN"). The 
server can receive internal event triggers from each uf t he us e r desktops via the network, and can 
also receive external event triggers, such as messages from the users' mobile data 
communication devices. In response to receiving one of these triggers, the server redirects the 
user's data items to the proper mobile data communication device. This alternative configuration 
could also include an Internet or Intranet-located web server including the redirector program 
that could be accessible through a secure Web page or other user interface. In this configuration, 
the redirector program could be located on an Internet Service Provider's ("ISP's") system, and 
the user would configure (and reconfigure) the program controls over an Internet connection to 
the ISP's system. 

In another embodiment, the redirector program operates at both the host system and at the 
user's mobile data communication device. In this configuration, the user's mobile device 
operates similarly to the host system described below, and is configured in a similar fashion to 
push certain user-selected data items from the mobile device to the user's host system (or some 
other computer) upon detecting an event trigger at the mobile device. This configuration 
provides two-way pushing of information from the host to the mobile device and from the mobile 
device to the host. 



CLLIT01 Doc: 427654_1 



The primary advantage of the present invention is that it provides a system and method 
for triggering the continuous and real-time redirection of user-selected data items from a host 
system to a mobile data communication device. Other advantages of the present invention 
include: (1) flexibility in defining the types of user data to redirect, and in defining a preferred 

5 list of message types that are to be redirected or preferred senders whose messages are to be 
redirected; (2) flexibility in configuring the system to respond to numerous internal, external and 
networked triggering events; (3) transparent repackaging of the user data items in a vanety ot 
ways such that the mobile data communication device appears as though it were the host system; 
(4) integration with other host system components such as E-mail, TCP/IP, keyboard, screen 

g saver, Web pages and certain programs that can either create user data items or be configured to 

| provide trigger points; and (5) the ability to operate locally on a user's desktop system or at a 

| distance via a network server or through a secure Internet connection. 

| These are just a few of the many advantages of the present invention, as described in 

fa more detail below. As will be appreciated, the invention is capable of other and different 
g embodiments, and its several details are capable of modifications in various respects, all without 
q departing from the spirit of the invention. Accordingly, the drawings and description of the 
K§ preferred embodiments set forth below are to be regarded as illustrative in nature and not 
restrictive.

TtPTATT.ED PPSPBIPTION QE THK DRAWINGS 
Referring now to the drawings, FIG. 1 is an example system diagram showing the 
redirection of user data items (such as message A or C) from a user's desktop PC (host system) 
10A to the user's mobile data communication device 24, where the redactor software 12 is 
5 operating at the user's PC 10A. As used in this application, the term "host system" refers to the 
computer where the redirector software is operating. In the preferred embodiment, the host 
system is a user's desktop PC 10A. Alternatively, however, the host system could be a network 
server (10B, see FIG. 2) connected to the user's PC via a local-area network ("LAN"), or it could 
be a Web server (240, see FIG. 6) operating through a secure network connection or operating at 
0 an external ISP, or the host system could be any other system that is capable of communicating 
■P with the user's desktop PC. 

Xt Message A in FIG. 1 represents an internal message sent from desktop 26 to the user's 

| host system 10A via LAN 14. Message C in FIG. 1 represents an external message from a 
sender that is not directly connected to LAN 14, such as the user's mobile data communication 
device 24, some other user's mobile device (not shown), or any user connected to the Internet 18. 
Message C also represents a command message from the user's mobile data communication 
device 24 to the host system 10A. As described in more detail in FIG. 3, the desktop host system 
10A preferably includes, along with the typical hardware and software associated with a 
workstation or desktop computer, the redirector program 12, a TCP/IP subsystem 42, a primary 
message store 40, an E-mail subsystem 44, a screen saver subsystem 48, and a keyboard 
subsystem 46. 

In FIG. 1, the host system 10A is the user's desktop system, typically located in the user's 
office. The desktop host system 10A is connected to a LAN 14, which also connects to other

scope of the invention, but rather to illustrate the variety of possibilities embodied in the 
redirection concept. 

The preferred mobile data communication device 24 is a hand-held two-way wireless 
paging computer, a wirelessly enabled palm-top computer, a mobile telephone with data 

5 messaging capabilities, or a wirelessly enabled laptop computer, but could, alternatively be other 
types of mobile data communication devices capable of sending and receiving messages via a 
network connection 22. Although it is preferable for the system to operate in a two-way 
communications mode, certain aspects of the invention could be beneficially used in a "one and 
one-half or acknowledgment paging environment, or even with a one-way paging system. The 

6 mobile data communication device 24 includes software program instructions that work in 

1 conjunction with the redirector program 12 to enable the seamless, transparent redirection of 

2 US er-selected data items. FIG. 4 describes the basic method steps of the redirector program 12, 
S and FIG. 5 describes the steps of the corresponding program operating at the mobile device 24. 

In an alternative embodiment of the present invention, not explicitly shown in the 
drawings, the mobile device 24 also includes a redirector program. In this embodiment, user 
selected data items can be replicated from the host to the mobile device and vice versa. The 
configuration and operation of the mobile device 24 having a redirector program is similar to that 
described herein with respect to FIGs. 1-4. 

A user of the present invention can configure the redirector program 12 to push certain 
user-selected data items to the user's mobile data communication device 24 when the redirector 
12 detects that a particular user-defined event trigger (or trigger point) has taken place. User- 
selected data items preferably include E-mail messages, calendar events, meeting notifications, 
address entries, journal entries, personal alerts, alarms, warnings, stock quotes, news bulletins,

3 other detectable occurrence that is external to the host system 10. 

* Internal events may include a calendar alarm, screen saver activation, keyboard timeout, 

programmable timer, or any other user-defined event that is internal to the host system 10. 
Networked events are user-defined messages that are transmitted to the host system from another 

20 computer coupled to the host system 10A via a network to initiate redirection. These are just 
some of the event triggers that could be used with the present invention to initiate replication of 
the user-selected data items from the host system 10A to the mobile device 24. Other types of 
triggers are also within the scope of the present invention.

FIG. 1 shows an E-mail message A being communicated over LAN 14 from computer 26 
„ Ore user's desktop system 10A (also shown in FIG. 1 is an externa! message C, which could be 
„ E-mail message ftom an Interne, user, or could be a command message from dr. user's mobile 
device 24). Once Ore message A (or C) rentes the primary message store of the host system 
,0A i. can be detected and acted upon by the redirection software 12. The redirection software 
, 2 crrn use many methods of detecting new messages. The preferred method of detecting new 
messages is using Microsoft's • Messaging API ("MAPI"), in which programs, such as tire 
redimcror progmm 12, regis.., for notifications or 'advise syncs' when changes to a mailbox take 
place. Other methods of detecting new messages could also be used. 

Assuming that tire red.rec.or program 12 is activated, and has been configured by tire user 
(either titrough .he sensing of an internal, externa!, or networked even.) to replicate certain user 
1 data i,ems (Including messages of type A or C, «o tire mobile device 24, when tire message A is 
received a. the host system 10A, tire redirector program 12 detects its presence and prepare, tire 
nressage for redirection to .he mobile device 24. In preparing the message for redirection, tire 
program 12 may compress tire original message A, it may jus, compreas tire message 
header, or U may encryp. tire entire message A .o create a secure link <o tire mobile device 24. 

The address of Ore user's mobile data communication device 24, tire type of device, and 
whether tire device 24 can accept certain types of attachment such as word processing or voice 
attachment* are also programmed inlo the redirector 12. If tire user's type of mobile device 
cannot accept a particular type of attachment then tire redimctor 12 can be programmed » route 
those attachments to a fax or voice number where the user is located using an attached fax or 
voice machine 30.

The redirector 12 may also be programmed with a "preferred list mode" operation that is 
configured by the user either at the host system 10A, or remotely from the user's mobile data 
communication device 24 by transmitting a command message C. The. "preferred list" in the 
"preferred list mode" contains a list of senders (other users) whose messages are to be redirected, 
or it may contain a list of message characteristics that determine whether a message is to be 
redirected, or it may contain both a list of senders and a list of message characteristics. For 
example, a message characteristic may relate to the size of the message, or the type of message, 
or whether the message has any attachments, or whether the message is originating from a 
particular domain. If activated, the preferred list mode causes the redirector program 12 to 
operate like a filter, only redirecting certain user data items based on whether the data item was 
sent from a sender on the preferred list or has certain message characteristics that if present will 
% trigger or suppress redirection of the message. 

| In the example of FIG. 1, if desktop system 26 was operated by a user on the preferred 

list of host system 10A, and the preferred list option was activated, then message A would be 
redirected. If, however, desktop 26 was operated by a user not on the host system's preferred 
list, then message A would not be redirected, even if the user of the host system had configured 
the redirector to push messages of type A. The user of the host system 10A can configure the 
preferred list directly from the desktop system 10A, or, alternatively, the user can send a 
command message (such as C) from the mobile device 24 to the desktop system 10A to activate 
the preferred list mode, or to add or delete certain senders or message characteristics from the 
previously configured preferred list. In this manner, the user can remotely control the operation 
of the preferred list mode filter so as to dynamically alter the filtering characteristics of the 
redirector program 12.

After the redirector 12 has determined that a particular message should be redirected, and 
it has prepared that message for redirection, the software 12 then sends the message A to a 
secondary memory store located in the mobile device 24. In doing so, the redirector preferably 
repackages message A as an E-mail with an outer envelope B that contains the addressing 
5 information of the mobile device 24, although alternative repackaging techniques and protocols 
could be used, such as a TCP/IP repackaging and delivery method (most commonly used in the 
alternative server configuration shown in FIG. 2). The wireless gateway 20 requires this outer 
envelope information B in order to know where to send the redirected message A. Once the 
message (A in B) is received by the mobile device 24, the outer envelope B is removed, and the 

0 original message A is placed in the secondary memory store within the mobile device 24. By 

1 repackaging and removing the outer envelope in this manner, the present invention causes the 

^ mobile computer 24 to appear to be at the same physical location as the host system 10, thus 

10 

creating a transparent system. 

In the case where message C is representative of an external message from a computer on 
the Internet 18 to the host system 10A, and the host 10A has been configured to redirect 
messages of type C, then in a similar manner to message A. message C would be repackaged 
with an outer envelope B and transmitted to the user's mobile device 24. In the case where 
message C is representative of a command message from the user's mobile device 24 to the host 
system 10A, the command message C is not redirected, but is acted upon by the host system 
20 10A. 

If the redirected user data item is an E-mail message, as described above, the user at the 
mobile device 24 sees the original subject, sender's address, destination address, carbon copy and 
blind carbon copy information. When the user replies to this message, or when the user authors a

Turning now to FIG. 3, a block diagram is set forth that demonstrates the interaction of 
the redirector software 12 with additional components of the desktop host system 10A shown in 
FIG. 1 (i.e., the desktop PC) to enable more fully the pushing of information from the host 
system 10A to the user's mobile data communication device 24. These additional components 
are illustrative of the type of event-generating systems that can be configured and used with the 
redirector software 12, and of the type of repackaging systems that can be used to interface with 
the mobile communication device 24 to make it appear transparent to the user. 

The desktop host system 10A is connected to LAN 14, and can send and receive data, 
messages, signals, event triggers, etc., to and from other systems connected to the LAN 14. 
Through the LAN, the system 10A can also communicate with external networks 18, 22, such as 
the Internet or a wireless data network. In addition to the standard hardware, operating system, 
|J and application programs associated with a typical microcomputer or workstation, the desktop 
% system 10A includes the redirector program 12, a TCP/IP sub-system 42, an E-mail sub-system 
S3 44, a primary data storage device 40, a screen saver sub-system 48, and a keyboard sub-system 
f5 46. The TCP/IP and E-mail subsystems 42, 44 are examples of repackaging systems that can be 
Si used to achieve the transparency of the present invention, and the screen saver and keyboard sub- 
systems 46, 48 are examples of event generating systems that can be configured to generate event 
messages or signals that trigger redirection of the user selected data items. 

The method steps carried out by the redirector program 12 are described in more detail in 
20 FIG. 4. The basic functions of this program are: (1) to configure and setup the user-defined event 
trigger points that will start redirection; (2) to configure the types of user data items for 
redirection and optionally configure a preferred list of senders whose messages are to be 
redirected; (3) to configure the type and capabilities of the user's mobile data communication 

16 

CLLIT01 Doc: 427654_1 



device; (4) to receive messages and signals from the repackaging systems and the event 
generating systems; and (5) to command and control the redirection of the user-selected data 
items to the mobile data communication 24 device via the repackaging systems. Other functions 
not specifically enumerated could also be integrated into this program. 

The E-Mail sub-system 44 is the preferred link to repackaging the user-selected data 
items for transmission to the mobile data communication device 24, and preferably uses industry 
standard mail protocols, such as SMTP, POP, IMAP, MIME and RFC-822, to name but a few. 
The E-Mail sub-system 44 can receive messages A from external computers on the LAN 14, or 
can receive messages C from some external network such as the Internet 18 or a wireless data 
& communication network 22, and stores these messages in the primary data store 40. Assuming 
| that the redirector 1 2 has been triggered to redirect messages of this type, the redirector detects 
J* the presence of any new messages and instructs the E-Mail system 44 to repackage the message 
by placing an outer wrapper B about the original message A (or C), and by providing the 
addressing information of the mobile data communication device 24 on the outer wrapper B. As 
noted above, this outer wrapper B is removed by the mobile device 24, and the original message 
A (or C) is then recovered, thus making the mobile device 24 appear to be the desktop system 
10A 

In addition, the E-Mail sub-system 44 receives messages back from the mobile device 24 
having an outer wrapper with the addressing information of the desktop system 10A, and strips 
this information away so that the message can be routed to the proper sender of the original 
message A (or C). The E-Mail sub-system also receives command messages C from the mobile 
device 24 that are directed to the desktop system 10A to trigger redirection or to carry out some

otter fbnction. The nuKtionatiry of the E-Mail sub-system 44 is continued by fhe redhector 
program 12. 

The TCP/IP sub-system 42 is an alternative repackaging syslem. It includes .11 of the 
functionality of the E-Mail sub-systetn 44, bu, instead of repackaging the user-selected data 
, items as standard E-mail messages, tins system 42 repackages the data items using special- 
purpose TCP/IP packaging ,echni q ues. This type of special-purpose sub-systent is useW in 
^nations where security and improved speed are important to the user. The provrs.on 0. a 
special-purpose wrapper that can only be removed by special software on the mobile device 24 
provides add* securfty, and by bypassing E-mail store and forward sysKms, the spead of 
W delivery of messages can be improved. 

t As described previously, the present invention can be triggered fo begin redirection upon 

" detecting numerous external, intern* and nerivorked even*, or nigger points. Examples of 
external even* include: receiving a command message from tire user's mobile dau 
communication device 24 to begin redirection; receiving a similar message from some external 
computer; sensing that the user is no longer in the vicinity of the host system; or any other even, 
dra, is external to tire bos, system. Interna, events could be a calendar alann, screen save, 
activation, keyboard timeout programmable timer, or any other user-defined even, tha, is 
i„,ema> fo tire bos, sys,em. Networked events are user-defined messages dra, rue transmrtten ti. 
d,e bos, sysfem from anotirer compu-e, lha, is connecud ,o the host system via a ne^-ork to 

20 initiate redirection. 

The screen saver and keyboard sub-systems 46, 48 are examples of systems that are 
capable of generating internal events. Functionally, the redirector program 12 provides the user 
with the ability to configure the screen saver and keyboard systems so that under certain

# 

conditions an event trigger will be generated that ean be detected by the redirector 12 to start the 
redireetion process. For example, the screen saver system can be configured so that when the 
screen saver is activated after, for example, 10 minutes of inactivity on the desktop system, an 
event trigger is transmitted to the redirector 12, which starts redirecting the previously selected 
user data items. In a similar manner, the keyboard sub-system can be configured to generate 
event triggers when no key has been depressed for a particular period of time, thus indicating that 
redirection should commence. These are just two examples of the numerous application 
programs and hardware systems internal to the host system 10A that can be used to generate 

internal event triggers. 

FIGs. 4 and 5, set forth, respectively, flow charts showing the steps carried out by the 
redirector software 12 operating at the desktop host system 10A, and the steps carried out by the 
| mobile data communication device 24 in order to interface with the host system. Turning first to 
FIG. 4, at step 50, the redirector program 12 is started and initially configured. The initial 
configuration of the redirector 12 includes: (1) defining the event triggers that the user has 
1 determined will trigger redirection; (2) selecting the user data items for redirection; (3) selecting 
the repackaging sub-system, either standard E-Mail, or special-purpose technique; (4) selecting 
the type of data communication device, indicating whether and what type of attachments the 
device is capable of receiving and processing, and inputting the address of the mobile device 24; 
and (5) configuring the preferred list of user selected senders whose messages are to be 
20 redirected. 

FIG. 4 sets forth the basic steps of the redirector program 12 assuming it is operating at a 
desktop host system 10A, such as shown in FIG. 1. If the redirector 12 is operating at a network 
server host system 10B, as shown in FIG. 2, then additional configuration steps may be

necessary to enable redirection for a particular desktop system .26. 28 connected to the server 
10B, including: (1) setting up a profile for the desktop system 26, 28 indicating its address, 
events that will trigger redirection, and the data items that are to be redirected upon detecting an 
event; (2) maintaining a storage area at the server 10B for the data items; and (3) storing the type 
of data communication device 24 to which the desktop system's data items are to be redirected, 
whether and what type of attachments the device 24 is capable of receiving and processing, and 

the address of the mobile device 24. 

Once the redactor program is configured 50, the trigger points (or event triggers) are 
enabled at step 52. T*e program 12 then waits 56 for messages and signals 54 to begin the 
redirection process. A message cou.d be an E-Mail message or some other user data item that 
ma y have been selected for redirection, and a signal could be a trigger signal, or could be some 
2 oth er type of signal that has not been configured as an event trigger. When a message or signal is 
detected, the program determines 58 whether it is one of the trigger events that has been 
configured by the user to signal redirection. If so, then at step 60 a trigger flag is set, indicafing 
that subsequently received user data items (in the form of messages) that have been selected for 
redirection should be pushed to the user's mobile data communication device 24. 

If the message or signal 54 is not a trigger event, the program then determines at steps 62, 
68 and 66 whether the message is, respectively, a system alarm 62, an E-Mail message 64, or 
some other type of information that has been selected for redirection. If the message or signal is 
none of these three items, then control returns to step 56, where the redirect waits for additional 
messages 54 to act upon. If, however the message is one of these three types of information, 
then the program 12 determines, at step 68, whether the trigger flag has been set, indicating that 
the user wants these items redirected to the mobile device 24. If the trigger flag is set, then at

step 70, the redirector 12 causes the repackaging system (E-Mail or TCP/IP) to add the outer 
envelope to the user data item, and at step 72 the repackaged data item is then redirected to the 
user's mobile data communication device 24 via LAN 14, WAN 18, wireless gateway 20 and 
wireless network 22. Control then returns to step 56 where the program waits for additional 

messages and signals to act upon. 

Although not shown explicitly in FIG. 4, after step 68 the program could, if operating in 



the preferred list mode, determine whether the sender of a particular data item is on the preferred 
list, and if not, then the program would skip over steps 70 and 72 and proceed directly back to 
step 56. If the sender is on the preferred list, then control returns to steps 70 and 72 for 
0 repackaging and transmission of the message from the preferred list sender to the mobile device

of the present invention, including, for example, storing the address of the user's desktop system 



At step 82, the mobile device waits for messages and signals 84 to be generated or 
received. Assuming that the redirector software 12 operating at the user's desktop system 10A is 
configured to redirect upon receiving a message from the user's mobile device 24, then at step 86 
the user can decide to generate a command message that will start redirection at the host system 
10A. If the user does so, then at step 88 the redirection message is composed and sent to the 
desktop system 10A via the wireless network 22, through the wireless gateway 20, via the 
Internet 18 to the LAN 14, and is finally routed to the desktop machine 10A.

• 



In this situation where the mobile device 24 is sending a message directly to the desktop 
system 10A, no outer wrapper is added to the message (such as message C in FIGs. 1 and 2). In 
addition to the redirection signal, the mobile device 24 could transmit any number of other 
commands to control the operation of the host system 10A, and in particular the redirector 
5 program 12. For example, the mobile 24 could transmit a command to put the host system 10A 
into the preferred list mode state, and then could transmit additional commands to add or subtract 
certain senders or certain message characteristics irom the preferred list Iii this maiuicx, Ihc 
mobile device 24 can dynamically limit the amount of information being redirected to it by 
altering the preferred list. 

g Other example commands include: (1) a message to change the configuration of the host 

-C system 10A to enable the mobile device 24 to receive and process certain attachments; and (2) a 

C3 

* A message to instruct the host system 10A to redirect an entire data item to the mobile device 24 in 

M 

the situation where only a portion of a particular data item has been previously redirected. 

Turning back to FIG. 5, if the user signal or message is not a direct message to the 
fg desktop system 10A to begin redirection (or some other command), then control is passed to step 

\Q 90, which determines if a message has been received. If a message is received by the mobile, 

5 

and it is a message from the user's desktop 10A, as determined at step 92, then at step 94 a 
desktop redirection flag is set "on" for this message, and control passes to step 96 where the 
outer envelope is removed. Following step 96, or in the situation where the message is not from 
20 the user's desktop 10A, as determined at step 92, control passes to step 98, which displays the 
message for the user on the mobile device's display. The mobile unit 24 then returns to step 82 
and waits for additional messages or signals.

# 

If the mobile device 24 determines that a message has not been received at step 90, then 
control passes to step 100, where the mobile 24 determines whether there is a message to send. 
If not, then the mobile unit returns to step 82 and waits for additional messages or signals. If 
there is at least one message to send, then at step 102 the mobile 24 determines whether it is a 
reply message to a message that was received by the mobile unit. If the message to send is a 
reply message, then at step 108, the mobile 24 determines whether the desktop redirection flag is 
on for this message. If the redirection flag is not on, then at step 106 the reply message is simply 
transmitted from the mobile device 24 to the destination address via the wireless network 22. If, 
however, the redirection flag is on, then at step 110 the reply message is repackaged with the 
outer envelope having the addressing information of the user's desktop system 10A, and the 
repackaged message is then transmitted to the desktop system 10A at step 106. As described 
^ above, the redactor program 12 executing at the desktop system then strips the outer envelope 
l and routes the reply message to the appropriate destination address using the address of the 
h desktop system 10A as the "from" field, so that to the recipient of the redirected message, it 
I appears as though it originated from the user's desktop system rather than the mobile data 
W 

v5 communication device. 

If, at step 102, the mobile 24 determines that the message is not a reply message, but an 
original message, then control passes to step 104, where the mobile 24 determines if the user is 
using the redirector software 12 at the desktop system 10A, by checking the mobile unit's 

20 configuration. If the user is not using the redirector software 12, then the message is simply 
transmitted to the destination address at step 106. If, however, the mobile determines that the 
user is using the redirector software 12 at the desktop system 10A, then control passes to step 
1 10, where the outer envelope is added to the message. The repackaged original message is then

With reference to FIG. 6, there is shown an example system diagram showing the . 
redirection of user data items, such as message A. from user A's desktop PC 204 to user B>s 
mobile data communication device 220, or alternatively, message B from user B>s mobile 
communication device 220 to user A. In this example, the messaging host system 230 maintains 
and stores data items received from the Internet 218 for user B in a message inbox. In this 
particular system example, the messaging host system 230 is preferably an Internet Service 
Provider ("ISP") that provides connectivity to the Internet 218 for a plurality of users, including 
user B. In another embodiment of the present invention, the messaging host 230 may be a web-

In another embodiment of the invention, the E-mail hosting service 



supplies a strictly wireless solution. 

In this embodiment of the invention, the messaging host system 230 is configured so as to 
forward a copy of all incoming data items destined for user B's inbox to a second host referred to 
herein as a wireless redactor host system 240. The wireless redirector host system 240 includes 
the wireless redirector program 242. Advantageously, data items destined for a user of the 
messaging host system 230 having a mobile communication device are continuously "pushed" to 
the wireless redirector host system 240 as they arrive at the messaging host system 230. Upon 
arrival at the redirector host system 240, a wireless redirector software program 242 operating at 
the system 240 determines whether such data items are user-selected data items to be pushed via 
a wireless network 222 to the user's mobile communications device 220. In this manner, user- 
selected data items are advantageously pushed out to the mobile communication device 220 
contemporaneously as they arrive to the messaging host system 230 so that the user need not be 
concerned about delays in receiving user-selected data items on the user's mobile communication

device via the wireless network 222. These filtering rules are similar to the "preferred list mode" 
20 operation described above with respect to the systems shown in FIGs. 1 and 2. 

Message A in FIG. 6 represents a data item, such as an E-mail message, sent from user

One of the objectives of the present invention is to be as non-obtrusive as possxble to the 
messaging host system 230 so as to make the invention simple to install and implement for ISPs. 
The messaging host system 230 may be configured in many ways to detect such messages. Since 
not all users of the ISP will have a mobile communication device 220, it is preferable that the 
system 230 includes a unique user file that is accessed and modified upon the arrival of any new 
message. The preferred method of detecting new messages, such as message A, is using Unix's 
"forward" file 238. Preferably, the redirection (or forwarding) of data items is accomplished by 
modifying the ".forward" file 238 typically found in the user's root directory at the messaging 
host system 230, such as an ISP. The ".forward" file is a simple ASCII text file comprising at 
least a list of one or more E-mail addresses (with some control information). The sendmail 
daemon 232 checks for the existence of this file 238, and uses its content to forward data items to 
H me app.opriate locations. Other methods of detecting and forwarding new data items destined 
for a user having a mobile communications device 220 could also be used and such other 
methods are well within the scope of the present invention. 

An example of the content of the ".forward" file modified for the present invention is: 
\bgilhuly@isp.net bgilhuly@wirelessredirectorhost.net 

In this example, the sendmail daemon 232 would redirect a copy of any incoming data items to 
those two addresses, namely "bgilhuly@isp.net" and 'n ) gimuly@wirele S sredirectorhost.net ." In 
the latter case, the data item would, preferably, be sent via the Internet to the wireless redirector 
host system 240 for further handling by the wireless redirector software program 242. The 
former address requires the sendmail daemon 232 to send the data item to user B's inbox of the 
local data item store 236. User B may access his data items in the inbox as he traditionally does 
- by, for example, POP3 or IMAP. In this manner, the forwarding activity is transparent to the 

27

ui 

U3 



user. The user B when viewing the inbox data items at his desktop PC 202 would know of the 
redirecting activity only by the message text that may be added to the messages as they are 
redirected by the mail handler. 

Assuming that the redirector program 242 is activated at the wireless redirector host 
5 system 240, and has been configured by the user to replicate certain user data items (such as 
message A) to the mobile communications device 220, when the message A is received at the 
wireless redirector host system 240, the redirector program 242 detects message A's presence 
and prepares the message for a second redirection to the mobile device 220. In preparing the 
message for the second redirection, the redirector program 242 may compress the original 
M message A, it may compress the message header, or it may encrypt the entire message A to create 
% a secure link to the mobile device 220. However, before the redirector program 242 compresses 

« -A 

It or encrypts the message A and redirects it to the mobile device 220, it examines stored user 

2 information and filtering rules that are associated with the recipient, user B, so as to determine 

m 

?n how the message A should be handled, 
fg A) Filtering 

W Preferably before the redirector program 242 begins preparing the message A for 

* 3 redirection, the redirector 242 examines the data item with respect to rules contained on a user B 
configurable filtering agent 250 (see, FIG. 7) which essentially is a database of rules that are to 
be applied for each user's incoming data items. The filtering agent 250 is preferably accessible 
20 by the user via the World Wide Web in a filter web page 252. The filter web page 252 allows the 
user, if the user so desires, to access and apply a plurality of filtering rules or any combination 
thereof that are to be applied to all incoming data items destined for that user. Preferably, in 
addition to filtering rules, web page 252 allows user B to switch between an active or inactive 
state for the redirection of user B's incoming messages. This switching feature is particularly 

28 

CLL1T01 Doc 427654_1 



useful during instances where user B is at his desktop PC 202 and accessing his inbox of the 
local store 236 and desires that the redirection of incoming mail to his mobile device 220 to be 
temporarily deactivated. The following criteria are exemplary of the types of filtering rules that 
may be available to the user: sendees); how addressed (To, CC, BCC); subject keyword(s); 
5 message keyword(s); and importance (high, low, normal). 

In any event, the filtering agent 250 is preferably hosted by the wireless redirector host 
system 240, but may be hosted by alternative host systems, including the messaging host system 
230 so long as the redirector program 242 has access to the most current set of rules and can 
make a determination whether any particular data item has satisfied all user-defined filtering 
tS rules. Alternatively implemented, the filtering agent 250 may be combined with the user profile 
database 254. Data items that do not clear the filtering rules are marked as "handled" by the 
redirector program 242 in the wireless data item store 248, and are not further handled by the 
redirector 242.

id 



B) User Profile 

Also accessible by the redirector program 242 is the address of the user's mobile data 



communication device 220, the user's SMTP address, the type of device 220, and whether the 
device 220 can accept certain types of attachments, such as word processing or voice 
attachments. This information is preferably maintained in a user profile database 254 (see, FIG. 
7). Such user information may be preferably created, updated and removed via a web-based user 
20 administration page 256. Web page 256 is preferably access-restricted to the system 
administrator of the messaging host system 230 who may from time to time add new users to the 
wireless redirection service. In addition to the above user information, the system administrator 
preferably has a switch control feature on the web page 256 to deactivate or activate redirection 
of the data items from the host system 230 that takes precedence over the user's selection on web 

29 

CLLIT01 Doc: 427654J 



page 252. This, advantageously, allows the system administer to maintain control over the value- 
added service described herein. 

If the user's type of mobile device 220 cannot accept certain types of attachments, then 
the redirector program 242 can be programmed to route the attachments to a fax or voice number 
5 where the user is located. The user may provide such information details to the redirector 
program 242 via a return message created at the mobile device 220. 

Advantageously, the web pages 252, 256 for configuring the filtering and user 
administration information used by the system preferably require that each user or host 
administrator login with a password before accessing the pages 252, 256. In addition, the web 
ffl pages 252, 256 are preferably designed with an interface look-and-feel that is similar to the 
S user . s ISP or web-based E-mail host system. In this manner, the messaging host system 230 can 
** be seen to be delivering a wireless E-mail solution with its traditional services. 
2 C) Redirection 

f After the redirector program 242 has determined that a particular message should be 

£ redirected, and it has prepared the message for redirection, the software 242 preferably converts 
W the message from MIME to CMTME (MIME is a standard Internet mail format, and CMIME is a 
compressed version of MIME), and then sends the message A to a memory store located in the 
mobile communications device 220 via the wireless gateway 250 and the wireless data network 
222. In doing so, the redirector program 242 preferably packages message A as a message with 
an outer envelope A' that contains the addressing information of the mobile device 220. In the 
preferred embodiment, the outer envelope is GME. The wireless gateway 260 requires this outer 
envelope information A' in order to know where to send the redirected message A. Once the 
repackaged message (message A in A') is received by the mobile device 220, the outer envelope 
A' is removed, and the original message A is placed in the second memory store within the 

30 

CLUT01 Doc: 427654_1 



20 



*0 



mobile device 220. By removing the outer envelope A' and presenting to the user of mobile 
device 220 message A , the present invention causes the mobile device 220 to appear to be at the 
same physical location as the messaging host system 230, or PC 202 in a transparent, seamlessly 
integrated Internet account hosted by messaging host system 230. 
D) Outgoing Data Item From Mobile 

If the redirected user data item is an E-mail message, as described above, then the user at 
t h e mobile device 220 s ee s the original subject line, s ender's add re ss, de s ti n at i on address, and 



carbon copy address. Preferably and desirably, the redirection of the E-mail message A is 
transparent to the mobile communication device user. When the user, at the mobile device 220, 
£0, replies to message A, or when the user authors a new message (a reply or a new message 

% collectively referred to as ''message B**), the software operating at the mobile device 220 adds a 

5 

H similar outer envelope (message B') to the reply message B (or the new message B) to cause 

CO 

CH message B to be routed to the wireless redirector host system 240 via the wireless network 222, 

CO 

e which then removes the outer envelope B\ repackages message B as message B'\ and redirects 

a 

JS message B" to the final destination, such as user A's PC desktop 204. 

The general flow of such transmission is shown as a dotted line in FIG. 6. In this 
embodiment of the invention, the removal of the outer envelope B' and repackaging of message 
B as envelope B" results in the outgoing redirected message B" from the wireless redirector 
host system 240 being sent using the E-mail address of the user's mailbox on messaging host 
20 system 230, rather than the address of the mobile device 220, so that it appears to the recipient of 
the message B" that the message originated from the user's desktop system 202 or from the 
messaging host system 230 itself (as would be the case of a web-based E-mail hosting system) 
rather than the mobile data communication device 220. This transparency functionality is 
accomplished by the redirector 242 modifying the "from** and <s reply to" identifiers associated 

31 

CLUT01 Doc: 427654_1 



with the message B to now have the SMTP address of user B's messaging host system 230 E- 
mail account. Advantageously, any replies to the message B» will then be sent to user B's inbox 
on messaging host system 230, which, if it is still in redirector mode, will repackage the reply 
and resend it to user B's mobile data device 220, as described above. 

In this embodiment, a copy of message B (labelled B") is redirected to user B's inbox at 
messaging host system 230 for retrieval and access by user B at some later time - for recording 
keeping purposes. In doing so, the redirector program 242 preferably repackages message B as 
message B"' so as to now have modified addressing information. In this preferred instance, the 
modified addressing information would include changing the "from" header information to read 
something to the following effect: "Sent from mobile communications device to recipient" where 
'recipient' would be the recipient's address of message B". This message B"» is forwarded, 
j* preferably via the Internet 21 8, to the messaging host system 230. 

As shown in FIG. 7, the messaging host system is preferably configured as an ISP. Here, 
the ISP system 230 includes a mail handler, such as a sendmail daemon 232, which forwards the 
1 copy B'" to the local data item store 236 by a local delivery agent (not shown). Further, user B 
may preferably configure his local inbox of data items at the desktop 202 to store such copy 
messages in a specific inbox for mobile data communications device data items. Of course in 
this illustrative example, messaging host system 230 is configured to redirect all incoming data 
items to wireless redirector host system 240; therefore, sendmail 232 would detect a new 
message and the ".forward" file 238 would again be accessed and the forwarding information 
therein acted upon. Consequently, message B'" is redirected (not shown) to redirector host 
system 240. At the redirector host system 240, the redirector is preferably programmed to detect 
that such a message B"> is only a redirection of message B'" sent therefrom. As such, the

redirector ignores this re-redirected message by preferably marking such messages as handled. 
Alternatively, the mail handler 232 at the messaging host system 230 is configured to detect such 
messages and to not redirect such messages. 

It is to be understood that a plurality of messaging host systems 230 may use a single 
5 redirector host system 240 for redirection of users' E-mail messages. Further still, a single 
redirector program 242 may be used to service the plurality of messaging host systems 230. 

Finally, turning to FIG. 8, a flow chart is set forth showing the steps carried out by the 
redirector program 242 operating at the redirector host system 240 shown in FIGs. 6 and 7. The 
basic steps carried out by the mobile communications device 220 in order to interface with the 
£B redirector host system 240 may be accomplished by substantially the same steps as shown in 
FIG. 5, although modified for this two-host aspect of the invention. 

The How chart in FIG. 8 assumes that the redirector program 242 has been activated and 



as 



S3 



is operating. Additional configuration steps will be necessary to enable redirection services for a 
new messaging host system 230. These additional configuration steps include: (1) setting up a 
profile for the new messaging host system 230 indicating its address, etc. (2) setting up 
individual user profiles, (3) initiating default filtering rules for incoming messages from the 
messaging host system for the users, and (4) making available both the filtering rule 252 and user 
profile 256 web pages. The flow chart also assumes the necessary steps have been undertaken to 
configure the messaging host system 230 to forward a copy of all incoming messages to the 
redirector host system 240 (i.e., the Unix ".forward" file has been properly configured.) 

Once the messaging host system 230 is configured 268 and the redirector program 242 is 
configured 270, the program 242 then waits for data items at step 272. As discussed earlier, data 



CLLIT01 Doc: 427654_1 



33 



items need not be limited to E-mail messages but may also include signals that are representative 
of user profile changes or filtering rule changes. 

When a data item is detected, the program determines at steps 274, 276 and 278 whether 
the data item is, respectively, a user profile change 274, a message from the Internet 276, or a 
message from the wireless mobile device 278. If the data item is a user profile change, then the 
appropriate user profile change is made at 280. Control then returns to step 272 where the 
program waits foradditional data items. If the data item is a message from the Internet, then the 
appropriate user profile information is checked and applied at step 290. The program then checks 
if the filter rules have changed at step 292. If so, the filter rules are reloaded. Next, the filter 
rules are applied at step 296. If the message does not clear all applicable redirection filter rules at 
| step 297, the preparation and redirection steps 298 and 300, respectively, are skipped. The 
J* message is thus ignored and control is returned to the redirector program 242 at step 272. 
2 Assuming, however, that the message (or at least a portion thereof) is to be redirected, then the 
message is prepared for redirection at step 298. In the preparation step 298, the redirector 
program 242 adds the outer envelope to the message for wireless transmission. At step 300, the 
Jd repackaged message is then forwarded to the user's mobile device 220 via LAN 258, wireless 
gateway 260 and wireless network 222. Control then returns to step 272 where the program 
waits for additional data items to act upon. 

If, at step 278, there is a determination that the data item is a message from the mobile 
device 220, then the message is prepared for Internet redirection at step 284. Preparation would 
preferably include changing the "from" and "reply to" fields of the message to replicate the 
address of the user's SMTP address at the messaging host system 230 - the resulting message 
referred to as message B" in FIG. 6. Also, the preparation step may include making a second

CLLIT01 Doc: 427654,1 



34 



copy of the message, such message referred to as message B'" in FIG. 6. In this second copy, 
the "from" field is changed to, preferably, "Sent from the mobile device to Recipient" where 
'Recipient' is the SMTP address of the recipient of message B'\ At step 286, previous messages 
or attachments are preferably appended. At step 288, one message is forwarded to the recipient 
5 (message B") and the copy of the message (message B"') is forwarded to the user's messaging 
host system 230 destined for the user's local data item store 236 for record keeping purposes. 
Control then returns to step 272, where the program waits for additional data items to act upon. 
If, at step 278, there is a determination that the data item is not a message from the wireless 
device, other functions may be performed by the redirector program 242 if so programmed to do 

CB so For instance, the message could be a command message such as described earlier in this

CO 

%_ Although not explicitly shown in the flowchart, if at step 276 there is a determination that

w 

steps are skipped (the message is ignored) and control is returned to step 272. In this manner, re- 
redirected messages are not redirected to the mobile device 220. Alternatively implemented, this 
determination could be undertaken at step 296 as part of the default filtering rules. It is to be 
understood that the user profile and filtering rules could alternatively be combined together, thus 
20 eliminating a step(s). This is, of course, well within the scope of the present invention. 

Although not shown, the additional step of maintaining the wireless data item store 248 is

ABSTRACT OF THE DISCLOSURE 

A system and method for pushing information from a host system to a mobile data 
communication device upon sensing a triggering event is disclosed. A redirector program 
operating at the host system enables a user to continuously redirect certain user-selected data 
5 items from the host system to the user's mobile data communication device upon detecting that 
one or more user-defined triggering events has occurred. The redirector program operates in 
connection with event- generating applications and repackaging systems at the host system to 
configure and detect a particular user-defined event, and then to repackage the user-selected data 
items in an electronic wrapper prior to pushing the data items to the mobile device.
