Call processing method and access network element in mobile communications system

摘要

The present invention relates to a call processing method and an access network element in a mobile communications system. In a signaling exchange process for setting up a call leg, a call leg identifier that identifies a logical resource allocated by an access network element to the call leg is carried, thereby reducing signaling exchange caused by setup or release of a service link between access network elements in the prior art, saving signaling overhead in a call process, and enhancing call access capabilities of a mobile communications system effectively. In addition, after the service link between the access network elements is set up, service packets can be forwarded between the access network elements in a self-addressing manner.

主权项

1. A call processing method, comprising:
sending, by an access network element, first signaling to a peer network element, wherein the first signaling carries a first call leg identifier that identifies a logical resource allocated by the access network element to a call leg; receiving, by the access network element, a service packet sent by the peer network element, wherein the service packet comprises the first call leg identifier; addressing, by the access network element and according to the first call leg identifier, the logical resource allocated by the access network element to the call leg; and sending the service packet to the logical resource so that the logical resource processes the service packet.
