Embodiment Construction

[0049] The schematic diagram of the system of this embodiment is as follows figure 1 As shown, including the first terminal 100, the second terminal 140, the first domain 110, the second domain 120, the called domain 130 and the domain switching controller 150, the called domain where the second terminal 140 is located may be the same as the first and second domains. The two domains are the same, or they may be another domain.

[0050] The domain switch controller 150 can be routed to both the first and second domains involved in the switch according to their respective routing modes, and the identifiers and addresses in the two domains may be different. The controller has the following three functional modules related to inter-domain switching:

[0051] A handover control module that can simultaneously control calls in two domains involving handover. It further includes a checking unit, which is used to check its service data when the terminal requests switching, and judges...

Abstract

The invention is concerned with the switch method and the system between the territory, and the using switch controller of the territory: sets the switch controller of the territory in the system with the first territory and the second territory that the two territory are routed, specifies a switch controller of the territory for the double-module terminal of the signed switch operation between the territory; the terminal A initiates the call of other terminals, establishes the signaling contact of the first territory and the switch controller of the territory, and saves the calling information and the correlation of the terminal A to the first territory or the first territory to other terminals; initiates the call from the second territory to inform the switch by the switch controller of the territory and carry the number of the terminal A when the terminal A needs to switch to the second territory; the switch controller of the territory establishes the call between the first territory and the second territory, and establishes the signaling link and the loading link from the terminal A, the second territory, the first territory and other terminals in the order; indicates release the signaling link and the loading link from the first territory to the terminal A. the invention can achieve the non-slot switch between at least two different territories.

Description

technical field [0001] The invention relates to an inter-domain switching method and a device for controlling call seamless switching between two domains in a wireless communication system. Background technique [0002] At the time of the second generation mobile communication system, there were two domains in the mobile communication system: GSM (Global System for Mobile communications, Global System for Mobile Communications) and GPRS (General Packet Radio Service, General Packet Radio Service). GSM mainly provides voice services and circuit type data services, while GPRS mainly provides high-speed data services. At the stage of Release 99 and Release 4 of the third-generation mobile communication system, the GSM and GPRS domains in the second-generation communication system have evolved into the UMTS CS (Universal Mobile Telecommunications System Circuit Switched, Universal Mobile Telecommunications System Circuit Switched) domain and the UMTS PS (Universal MobileTelecom...
