Problems solved by technology

[0010] For the UE with ISR activated, if the MME and SGSN that established the ISR association are connected to different MSCs or the MSC only maintains one of the SGs interface connection or the Gs connection, then when there is a called service, the MSC currently registered by the UE can only be in the When paging a UE in an effective network, the UE may not be paged at this time, so the service cannot be carried out normally.

Abstract

The embodiment of the invention discloses a method and device for establishing connection with MSC. The method comprises the following steps: when the terminal is switched from a first network to a second network, a second network entity in the second network acquires the information of a first MSC of the terminal in the first network, wherein the first network is connected with the first MSC; and the second network entity establishes the connection with the first MSC according to the acquired information of the first MSC. The technical scheme of the embodiment of the invention ensures that the connected MSC can continue providing services for two networks, thereby continuously providing services for users and enhancing stability of the services of users.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and a device for establishing a connection with an MSC (Mobile Switch Center, mobile switching center). Background technique [0002] In the evolved packet network (evolved packet system, EPS) architecture where GPRS (Genreral Packet Radio Service, General Packet Radio Service) / UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) and CS (Circuit Switched, Circuit Switched) coexist , since many existing services run in the circuit domain of GPRS / UMTS, in order to reuse the existing CS services in EPS, a method of connecting to the core network of CS domain through the EPS network is proposed. The MME (Mobility Management Entity, mobility management entity) is connected to the MSC of the traditional CS core network through an SGs interface. [0003] Under this architecture, when a UE (User Equipment, user equipment) i...
