Handling of Access Capability Information in a Mobile Network

摘要

In a mobile network with a plurality of access networks, a control node which is controlling access of a user equipment to that one of the access networks which is currently used by the user equipment determines an access capability of the user equipment in said access network, e.g. support of voice communication over packet switched access. The control node provides an indication of the determined access capability to a subscriber database associated with the user equipment. The indication may then be retrieved from the subscriber database and be used to control termination of a connection to the user equipment.

1. A method of controlling termination of a connection to a User Equipment (UE) in a mobile network comprising a plurality of access networks, the method comprising:
determining, by a packet switched control node, an access capability of the UE in an access network being currently used by the UE, the packet switched control node controlling access of the UE to the access network, and the access network being one of the plurality of access networks; transmitting first information indicating the determined access capability to a Home Subscriber Server (HSS) associated with the UE; transmitting second information indicating the determined access capability by the HSS to a Service Centralization and Continuity Application Server (SCC-AS) that is configured to control termination of connections to the UE; and controlling termination of the connection to the user equipment, by the SCC-AS, based on the determined access capability.
