Abstract

The invention discloses an address obtaining method, a signaling routing method, a communication system and relevant equipment, which are used for realizing the routing of Layer 3 signaling when UE is attached to an EPS. The signaling routing method of the invention comprises the steps that: a mobile management entity receives an address obtaining request sent by the UE; during a load establishing process of the mobile management entity and a grouped data network gateway, the routing address of a destination end is obtained; the Layer 3 signaling is packaged; in addition, the invention also provides the communication system, the user equipment and the grouped data network gateway correspondingly. The invention can effectively realize the routing of the Layer 3 signaling when the UE is attached to the EPS.

Description

technical field [0001] The present invention relates to the communication field, in particular to an address acquisition method, a signaling routing method, a communication system and related equipment. Background technique [0002] In the traditional second generation (2G, 2 nd Generation) communication network, the voice service is transmitted using a circuit switched (CS, Circuit Switched) network, and the Internet voice (VoIP, Voice Over IP) service can be transmitted using a PS. [0003] An Evolved Packet Switched (EPS, Evolved Packet Switched) network is used as an IP transmission network, and all voices need to be transmitted through the IP network. However, in the initial stage of EPS network establishment, there will inevitably be incomplete network coverage. At this time, UEs in 2G, third-generation (3G, rd Generation) communication system and EPS network, for the voice service, it is necessary to consider the possibility of switching between the EPS system and...
