Embodiment Construction

[0047] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0048] The embodiment of the present invention proposes a variety of methods for negotiating CSoPS service capabilities between the UE and the network side. Through the embodiment of the present invention, the UE actively sends the CSoPS capability information supported by the UE to the network side, so that the network side can The CSoPS capability of the network side and the network side’s own configuration select an appropriate method for the UE to perform subsequent processing. If the network side supports the extended architecture, and the UE also supports the extended architecture, the network side can notify the UE that the network side supports CS services on the EPS network. Therefore, the UE does not need to switch to the 2G / 3G network when processing the CS service.

Abstract

The embodiment of the invention discloses a method for CSoPS capability negotiation. The method comprises the following steps: MME receives a request message sent by user equipment; the MME judges whether CSoPS capability information of EU is included in the request message; if the judged result shows that the CSoPS capability information is included, the MME selects one CSoPS capability for UE according to the CSoPS capability information reported by UE and network configuration information. The embodiment of the invention ensures that UE and network side equipment can negotiate the service capability of CSoPS, so that different UE in the same EPS network adopting various CSoPS frameworks to fulfill service can be ensured, and one UE in various networks adopting various CSoPS frameworks to fulfill service can be ensured.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a CSoPS capability negotiation method, system and device. Background technique [0002] A CS (Circuit Switch, circuit switching) domain and a PS (Packet Switch, packet switching) domain exist in a 2G / 3G network, which process CS domain services and PS domain services respectively. Among them, in the CS domain, the core network control plane entity is a mobile switching center MSC (Mobile Switching Center, mobile switching center), and in the PS domain, the core network control plane entity is an SGSN (Serving GPRS Support Node, serving GPRS support node ). There is a Gs interface between the SGSN and the MSC, and the UE (User Equipment, user equipment) can perform a joint GPRS (General Packet Radio Service, General Packet Radio Service) and IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) attachment process, While th...
