Embodiment Construction

[0098] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0099]The inventor noticed during the invention process: in order to make the second-generation network and the third-generation network better intercommunicate, the interface between the BSC and the RNC added by the 3GPPGERAN (GPRS EDGE RAN) working group: the Iur-g interface.

[0100] Therefore, signaling can be transmitted through the Iur-g interface to trigger the execution of the service handover process between TD-SCDMA and GSM, so as to reduce the excessive number of CN network elements involved in the handover in the prior art and the complicated interaction , resulting in a large handover delay and a low success rate.

[0101] figure 2 It is a schematic diagram of the implementation process of the service handover method between communication systems, as shown in the figure, which may include the following steps:

[0102] Step 201, judging w...

Abstract

The invention discloses a method and equipment for switching service between communication systems. The method comprises the following steps of: judging whether the communication service of UE needs to be switched from a TD-SCDMA system to a GSM system; when the switch is determined, initiating a repositioning instruction through an Iur-g interface; and executing the switch of the communication service between the systems according to the repositioning instruction. The method and the equipment can reduce the switching delay from TD-SCDMA to GSM, and improve the switching success rate.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a service switching method and equipment between communication systems. Background technique [0002] In the prior art, TD-SCDMA (Time Division Synchronous CDMA, Time Division Synchronous CDMA system, is one of the 3G network standards defined by the 3GPP organization; CDMA: Code Division Multiple Access, Code Division Multiple Access) is developing towards GSM (Global System for Mobile communication (Global System for Mobile Communications) switching is performed in accordance with the 3GPP R8 2008.12 TS25.413 protocol. [0003] figure 1 It is a schematic diagram of the implementation process of switching from TD-SCDMA to GSM under the TS25.413 protocol, as shown in the figure, in this process: [0004] 1. Start the Call Setup Procedure (call setup procedure) in the 3G network, including: RRC connection setup, security mode control, RAB setup, etc. (RRC connectio...
