A METHOD OF, A SYSTEM AND DEVICE FOR INITIALIZING A COMMUNICATION SESSION IN A COMMUNICATIONS NETWORK

摘要

A party (2) in a telecommunications network (1) comprises access information (3) pertaining to communication capabilities the party (2) is able to handle. The party (2) is registered (4) with a unique identity (6) and at least one network contact address (7) at a server (5). Access information required for setting up a communication session with the party (2) is retrieved by initiating, by an entity (8) in the network (1), of a contact request (9) to the server (5) for at least one network contact address (7) of the party (2) from which access information of the party (2) is available. The server (5) forwards the at least one network contact address (6) of the party (2) in a token (10). Using the received at least one network contact address (6), the entity (8) initiates an access request (11) to the party (2) for retrieving access information (3) and receives access information (12) from the party (2) in response to the access request (11).
