AI Technical Summary

Problems solved by technology

[0004] The development time of the WCDMA system in various countries is relatively short, and the PHS system is not a global unified standard, and its commercial use is few in countries and regions, so there are relatively few studies on handover between the two systems. There is no information available on the specific implementation of switching

Embodiment Construction

[0028] In the present invention, a terminal capable of switching from a PHS system to a WCDMA system must have a dual-mode or multi-mode terminal capable of supporting both the WCDMA system and the PHS system.

[0029] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0030] The flow process of an embodiment of the method of the present invention is as figure 1 shown, from figure 1 As can be seen:

[0031] (1) In the PHS system, after measurement and judgment, if it is considered that handover is necessary, the PHS system sends a message (such as a "handover preparation" message) to the WCDMA system to request handover (ie step 101). The handover request message needs to carry service-related information of the mobile user, so that resource allocation and the like can be performed in the WCDMA system.

[0032] (2) After the WCDMA system prepares the corresponding resources, it returns a "response" messag...

Abstract

A switch method between the systems of PHS and WCDMA is that the terminal or the network judges to carry out initial switch according to the measurement to adjacent regions between the systems by the terminal and determines the necessary switch region then to switch in light of the following steps: PHS sends information to WCDMA for switch which returns back the switch response to PHS after preparing related resources, PHS sends instructions of switch to WCDMA which sends the information of switch success to PHS after the terminal is able to communicate normally in the system, PHS releases all resources originally occupied by the said terminal.

Description

technical field [0001] The invention relates to a switching method between a Wideband Code Division Multiple Access (WCDMA) system (hereinafter referred to as WCDMA) and a PHS (Personal Handy phone System), in particular to a switching execution method between PHS and WCDMA systems. Background technique [0002] With the wide application and rapid development of mobile communication systems, many key technologies in mobile systems are becoming more and more perfect. While realizing normal communication of users, it is also necessary to consider how to obtain the best performance, and obtain the best performance for both the system and user equipment. Better satisfactory results. [0003] In China, WCDMA, one of the main standards of the third-generation mobile communication, will soon be widely used. At the same time, the PHS system is also widely used in China, so there will be a coexistence of WCDMA and PHS. In this case, realizing the smooth transition from PHS to WCDMA ...
