Problems solved by technology

In this way, the call can be received by other UEs than the UE in the first session, which prevents the UE in the first session from using the concurrent session handling function
Furthermore, it may be difficult for the user to use both UEs involved in the session at the same time, or the second session may not be answered by the user (for example, after the user leaves one of their UEs at home and someone at home hears the UE's ringtone and in the case of an answer on behalf of the user)

Embodiment Construction

[0017] Problems with routing session initiation requests to multiple user equipments (UEs) associated with a given user have been identified above. The present invention proposes a solution to these problems. This solution ensures that when a user with multiple user equipments (UEs) is already in a session (eg voice or video call) on one of the UEs, future session initiation requests are directed to that UE only. Exemplary implementations are described below, but in each case the user's session establishment signaling is directed via an application server in the user's home network.

[0018] figure 1 The method performed by the application server is shown in . The application server keeps a record of ongoing sessions, including the user's address, and which of the user's devices was used for the call (not shown). When an application server receives a session initiation request (eg, SIP INVITE) (S101), it will check whether the destination address of the session initiation r...

Abstract

The present disclosure provides a method of processing a SIP session initiation request in an IP Multimedia Subsystem (IMS) network. The method is performed at an Application Server (AS) within the network. The AS receives a session initiation request that includes a destination address that is currently associated with a plurality of registered user equipments (UEs). The AS then determines whether the UE associated with the destination address is already in a session. If yes, the AS causes the session initiation request to be forwarded only to that UE. If not, the AS causes the session initiation request to be forwarded to all UEs registered for that address.

Description

technical field [0001] The invention relates to the handling of session initiation requests in a telecommunications network. In particular, the invention relates to the handling of requests in case a user has multiple user devices. Background technique [0002] With the increasing use of mobile telecommunication networks in everyday life, many users now have multiple user equipments (UEs). For example, a user may own a tablet computer, a personal mobile phone, a business mobile phone, and so on. To simplify the experience for such users, IP Multimedia Subsystem (IMS) networks provide the functionality for users to have a single SIP address pointing to multiple UEs (eg, a user may have a single phone number associated with multiple UEs). When an INVITE request is sent to a user's SIP address, the network distributes the INVITE request to each UE associated with that address. A session will be established with whichever UE that first responds with a 200 OK (200 Success) acc...
