Handling of Access Capability Information in a Mobile Network

摘要

In a mobile network with a plurality of access networks, a control node controls access of a user equipment to that one of the access networks which is currently used by the user equipment. The control node determines an access capability of the user equipment in the access network. The access capability includes whether an IP Multimedia Subsystem (IMS) voice over Packet Switched (PS) session is supported. The control node provides an indication of the determined access capability to a Home Subscriber Server (HSS) associated with the user equipment. The indication may then be retrieved from the HSS and used to control termination of a connection to the user equipment.

1. A method of controlling communication of a user equipment in a mobile network with a plurality of access networks, the method comprising:
controlling, by a control node, access of the user equipment to that one of the access networks which is currently used by the user equipment, wherein the control node has functionality of either or both of a Mobility Management Entity (MME) and a Serving GPRS Support Node (SGSN); determining, by the control node, an access capability of the user equipment in the access network currently used by the user equipment, the access capability comprising whether an IP Multimedia Subsystem (IMS) voice over Packet Switched (PS) session is supported; and providing, by the control node, an indication of the determined access capability to a Home Subscriber Server (HSS) associated with a subscriber using the user equipment.
