Method and device for processing a piece of information indicative of a desire to be involved in at least one user application session

Abstract

A method and apparatus are provided for processing an item of information indicative of a desire for involvement in at least one application session, established according to the SIP protocol, in progress for a user of a telecommunications network. The at least one session is controlled by a first terminal of the user. The method is implemented by the first controller terminal, and includes receiving a notification of an event relating to the user, which includes at least one item of information indicative of a level of involvement desired by a second terminal of the user, and making a decision relating to the desired level of involvement. In the case of a positive decision, an involvement command is transmitted relating to the level of involvement desired by the second terminal to the telecommunications network.

 means for reception of a notification of an event relating to the user, comprising at least one item of information indicative of a level of involvement desired by a second terminal of said user;   means for making a decision making relating to the desired level of involvement; and   means for, in the case of a positive decision, dispatching an involvement command relating to said level of involvement desired by the second terminal to the telecommunications network.   
     
     
         7 . A method of involvement in at least one application session, established according to the SIP protocol, in progress for a user of a telecommunications network, said session being controlled by a first terminal of said user, wherein said method, implemented by a second terminal of said user, comprises:
 a step of sending a notification of an event relating to said user comprising at least one item of information indicative of a level of involvement desired by the second terminal in said at least one application session.   
     
     
         8 . The method of involvement in at least one application session in progress as claimed in  claim 7 , wherein said event notification is published at a presence server able to transmit the event notification to terminals of the user having previously subscribed thereto. 
     
     
         9 . The method of involvement in at least one application session in progress as claimed in  claim 7 , wherein, subsequent to prior reception of a request for subscription to a mechanism for notification of an event relating to a state of said user by the first terminal with the second terminal, the event notification is dispatched to said first terminal. 
     
     
         10 . The method of involvement in at least one application session in progress as claimed in  claim 7 , wherein the method comprises:
 a step of obtaining information comprising a list of identifiers of application sessions in progress between said user and the network and wherein the step of sending an item of information indicative of a level of involvement desired by the second terminal comprises the identifier of the targeted application session.   
     
     
         11 . A device for involvement in at least one application session, established according to the SIP protocol, in progress for a user of a telecommunications network, said session being controlled by a first terminal of said user, wherein said device, implemented by a second terminal of said user, comprises:
 means for sending an event notification comprising at least one item of information indicative of a level of involvement desired by the second terminal in said at least one application session.   
     
     
         12 . A terminal of a user of a telecommunications network, wherein the terminal is configured to control at least one application session, established according to the SIP protocol, in progress between the user and said telecommunications network, and wherein the terminal comprises:
 a device configured to process an item of information indicative of a desire for involvement in at least one application session,
 the device for processing comprising: 
 means for reception of a notification of an event relating to the user, comprising at least one item of information indicative of a level of involvement desired by a second terminal of said user; 
 means for making a decision making relating to the desired level of involvement; and 
 means for, in the case of a positive decision, dispatching an involvement command relating to said level of involvement desired by the second terminal to the telecommunications network; and 
   a device configured for involvement in at least one application session in progress, which comprises means for sending an event notification comprising at least one item of information indicative of a level of involvement desired by the second terminal in said at least one application session.   
     
     
         13 . A presence server in a telecommunications network, comprising:
 means for receiving information relating to a user and published by a second terminal of a user registered in the network,   means for storing said information,   means for recording a request for subscription to a notification of an event relating to said user of at least one first terminal of said user, and means for notification of an event relating to said user of said first terminal of the user wherein said information comprises at least one item of information indicative of a desired level of involvement of the second terminal in at least one application session, established according to the SIP protocol, in progress between the first terminal and the telecommunications network.
