CLAIMS 

1. Method for monitoring media session flow in a 
telecommunication network comprising a media-handling 
node (MHN) through which, sessions between subscribers 

5 are transported via first ports (PI1-PI5) and second 

ports (P01-P05) characterised by assigning an extra port 
(XP1-XP5) to the media-handling node (MHN) for each new 
session that is transported through the node, which 
method comprises the following further steps: 

10 - storing in a database (LI-DB) , identification of a first 
subscriber (A) for which monitoring is desired; 

setting up a connection between the first subscriber (A) 
and a second subscriber (B) ; 

- assigning an extra port (XP1) that is adherent to the 
15 session between the first and second subscriber (A, B) ; 

- connecting the assigned extra port (XP1) that is adherent 
to the session between the first and second subscriber (A, 
B) ; 

- monitoring the session between the first and second 
20 subscriber via the connected extra port (XP1) . 

2. Method for monitoring media session flow in a 
telecommunication network according to claim 1, which 
method comprises the following further step: 

25 - sending an indicator (FLAG) from the database (LI-DB) 
indication that the extra port (XP1) is to be connected. 



3. Method for monitoring media session flow in a 
telecommunication network according to claim 2 whereby

WO 2005/025133 



PCT/SE2003/001392 



the indicator (FLAG) is sent from the database (LI-DB) 
to the media-handling node (MHN) . 

4. Method for monitoring media session flow in a 
5 telecommunication network according to any of claim Ito 

3, which method comprises the following further step: 

setting up a three-part conference between the two 
involved subscribers (A and B) and a monitoring facility 
(LEMF) .

5. Arrangement to monitor media session flow in a 
telecommunication network comprising a media-handling 
node (MHN) through which, sessions between subscribers 
are transported via first ports (PI1-PI5) and second 

15 ports (POl-POS) characterised by 

- means for assigning an extra port (XP1-XP5) to the media- 
handling node (MHN) for each new session that is 
transported through the node; 

- means for storing in a database (LI-DB) , identification of 
20 a first subscriber (A) for which monitoring is desired; 

- means for setting up a connection between the first 
subscriber (A) and a second subscriber (B) ; 

- means for connect an assigned extra port (XP1) that is 
adherent to the session between the first and second 

25 subscriber (A, B) ; 

means for monitoring the session between the first and 
second subscriber via the connected extra port (XP1) .

6. Arrangement to monitor media session flow in a 
telecommunication network according to claim 5 
comprising means for sending an indicator (FLAG) from 
the database (LI-DB) indication that the extra port 
(XPl) is to be connected. 



7. Arrangement to monitor media session flow in a 
telecommunication network according to claim 5 or 6 
comprising means for setting up a three-part conference 
10 between the two involved subscribers (A and B) and a 

monitoring facility (LEMF) .
