  • UEs As mobile telecommunications networks are used more and more in everyday life, many users now have multiple user equipments, UEs. For example, a user may have a tablet, a personal mobile phone, a business mobile phone, a PC with SIP/IMS enabled software, etc. Different devices are more or less suitable for different types of sessions, for example the larger screen of a tablet makes it more suitable for video calling than a smartphone, and smartphones are generally more economically suited for voice calls, as well as often having better microphones.

Upon receipt of the request (S1 12), the node 200 stores the fact that UE-2 has made such a request.

  • UE-2 sends a SIP SUBSCRIBE to the node 200.

  • UE-1 establishes a session with a remote UE (S101 ), and this establishment is detected by the node 200 (S102). Rather than sending the indication of session establishment immediately, the node 200 records that UE-1 is involved in an ongoing session with UE-2, and waits for a request for session establishment indication.
  • UE-2 sends a request for session establishment indication (S121 ) to the node 200. This may be in response to user input, or UE-2 may periodically "poll" the node 200 by sending requests for session establishment indication.

  • a further improvement that can be made to any of the methods above is the addition of authorisation prior to the node 200 sending the indication of session establishment.
  • This can be achieved in various ways, for example by having the user input some identification token (e.g. a Personal Identification Number, PIN) which is then sent to the node 200 (e.g. in response to a query from the node 200 or as part of a request for session establishment indication).
  • the node 200 may determine the location of the UE-1 and the other UEs associated with the user, and only send the indication of session establishment to those located within a predefined range. This may be achieved by requesting GPS data from the UEs, or by determining which basestations of a cellular network the UEs are connected to. If the UEs are in close proximity, it can be assumed that they are in control of the same user.

Abstract

L'invention concerne un procédé exécuté dans un réseau de télécommunication. Le procédé consiste à détecter l'établissement d'une session entre un premier équipement utilisateur (UE) associé à un utilisateur et un UE à distance; après une telle détection, à envoyer une indication de l'établissement de session à un ou à plusieurs autres UE associés à l'utilisateur, l'indication comportant une identité pour l'UE à distance ou un utilisateur de l'UE à distance. Le procédé comprend en outre des étapes exécutées dans au moins l'autre ou l'un des autres UE. L'autre UE reçoit une indication d'établissement de session entre le premier UE et l'UE à distance, l'indication comportant une identité pour l'UE à distance ou un utilisateur de l'UE à distance. L'autre UE initie ensuite une session en utilisant l'identité pour l'UE à distance ou un utilisateur de l'UE à distance.
