Problems solved by technology

The characteristics of the third generation (3rd Generation, referred to as "3G") mobile communication system, such as high bandwidth, multiple services, and high quality, have greatly attracted the mobile consumer market. Restrict market expansion to a certain extent and affect the development of mobile operations
However, when the handover occurs, the MGW deletes the original IWF and replaces it with a new IWF entity. The IWF needs to negotiate with the mobile station on the wireless side, resulting in the interruption of the original data communication. If handover occ...

Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0066] The main principle of the present invention is that the MSCe indirectly or directly provides the MGW with information about the time and object of service switching, and instructs the MGW to transfer the IWF entity resources attached to the original bearer channel, that is, the old T, to the new bearer channel, that is, the new In terms of T, since the IWF entity remains unchanged before and after the handover, it can avoid re-negotiation between the IWF and the mobile station, and maintain a smooth transition of the data service before and after the handover.

[0067] The key problem to be solved by the present invention is that the same IWF entity is used before and after switching. This requires that when MSCe receives a handover request and adds a new T...

Abstract

A method for switching service in the third generation of mobile communication system includes using MSCe to inform MGW to derive off IWF entity on old T and using new T to it take over when switch is occurred for ensuring to use one and the same IWF entity resource before and after switch in order not to interrupt service; enabling MSCe to inform MGW object and time transferred by IWF indirectly by changing variation of topology relation of new and old T to service opposite T; setting up a virtual T to be used as opposite T for QNC service.

Description

technical field [0001] The invention relates to the third-generation mobile communication technology, in particular to a service switching method in the third-generation mobile communication system. Background technique [0002] With the rapid development of communication technology, people's expectations and requirements for personal communication are getting higher and higher, so mobile operators need to pay special attention to aspects such as user interface and service quality that directly affect the effect of users using mobile services. The characteristics of the third generation (3rd Generation, referred to as "3G") mobile communication system, such as high bandwidth, multiple services, and high quality, have greatly attracted the mobile consumer market. To a certain extent, it restricts market expansion and affects the development of mobile operation affairs. [0003] During the evolution of the 3rd Generation Partnership Project 2 (3GPP2) system from the circuit-s...
