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

[0021] In the present invention, the UE capable of switching from the WCDMA system to the PHS system must be a dual-mode or multi-mode terminal capable of supporting both the WCDMA system and the PHS system.

[0022] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0023] The method flow process of the present invention is as shown in Figure 1, as can be seen from Figure 1:

[0024] (1) After the SRNC judges the handover, it sends a message requiring handover (such as a "relocation request" message) to the CN (ie step 101). The sending of this message is the first step of the message flow after the SRNC considers it necessary to handover the UE to the PHS system. There are many situations that trigger this decision, such as: A. The quality of the current carrier frequency measured by the UE is poor; B. The user signs with the operator first in the PHS network; C. The quality of the PHS system cell is real...

Abstract

The method for executing switching include following steps: after switching decision is made that a user's device is needed to switch, SRNC sends message of switching request to CN; CN sends message of switching request to kernel switching network of PHS system, kernel switching network of PHS system records and saves the message and returns response message to CN; CN sends message of relocate command to SRNC; SRNC sends 'switching between systems' command to UE; UE launches request for building link channel to controller of its base station; base station controller of PHS sends message of 'switching request' to kernel switching network; when CN determines that switching is completed, resources assigned for the UE is released. The invention treats switching flow from WCDMA system to PHS system so as to realize UE possessing capability of dual mode.

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 WCDMA and PHS 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 ...
