Problems solved by technology

[0015] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: in the prior art, when the user equipment switches from the 3G network to the 2G network and uses the Iur-g interface to maintain the connection, if the user equipment is in If a cross-BSS handover occurs again in the 2G network, the RNS needs to cooperate to complete the cross-BSS handover, which makes the signaling process between the RNS, S-BSS, and T-BSS complicated during the re-handover process, and the handover time is long

Embodiment Construction

[0031] A handover method, device, and system provided by embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Such as figure 2 As shown, it is a handover method provided by an embodiment of the present invention, the method includes:

[0033] 201: When the user equipment is in the connection hold state after being handed over from the first network to the second network, receive the handover request sent by the source base station subsystem through the interface between the source base station subsystem BSS and the target base station subsystem BSS in the second network ;

[0034] 202: Switch the user equipment according to the switching request.

[0035] In order to more clearly illustrate the method and device for handover of user equipment between base station subsystems, the reference architecture of the Iur-g interface mentioned in the embodiment of the present invention is firstly described.

Abstract

A switching method, device and system are disclosed in the embodiments of the present invention which refer to a field of mobile communication technology. The switching method provided by the embodiments of the present invention includes: when a user equipment is in the connection holding state after switching from a first network to a second network, via an interface between a source base station subsystem (BSS) and a target base station subsystem (BSS) in the second network, receiving a switching request sent by the source base station subsystem; switching the user equipment according to the switching request. With the present invention, re-switching flow can be optimized and re-switching time can be shortened.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a handover technology of user equipment between base station subsystems. Background technique [0002] At present, there are multiple standards in the network at the same time, for example: GSM (Global System for Mobile Communications, Global System for Mobile Communications) in 2G networks, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) in 3G networks, TD-SCDMA (Division-Synchronous Code Division Multiple Access, time-division synchronous code division multiple access technology), CDMA2000 (Code Division Multiple Access 2000, code division multiple access 2000), etc. Therefore, various interoperability exists among the various systems, for example: CS (Circuit Switched Domain, Circuit Switched Domain) handover from 2G to 3G, CS handover from 3G to 2G, and so on. In order to make the 2G network and the 3G network better intero...
