Embodiment Construction

[0028] The method of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] In the present invention, the mobile station that can implement WCDMA system handover to PHS system must possess dual-mode or multimode terminals that can support WCDMA system and PHS system, and the mobile station needs to have dual transceivers. After receiving the handover command, use Another transceiver looks for a suitable cell in the PHS system and initiates a link channel establishment request to its base station controller. At this time, the original transceiver continues to maintain the connection with the WCDMA system and the normal conversation process.

[0030] like figure 1 Shown, the concrete flow process of the inventive method is as follows:

[0031] (1) SRNC (Serving Radio Network Controller, Serving Radio Network Controller) decides that handover is required, and then sends an inter-system handover command to the mobile station,...

Abstract

The invention discloses an executing for switching from WCDMA system to PHS system, including: WCDMA system transmits system-to-system switching command to a mobile station; the mobile station receives the command, and then searches PHS system for a proper cell and transmits a request for link channel establishment to the its base station controller; if the base station controller can allocate channel to establish connection, it sends the information about switching request to its kernel exchange network; the kernel exchange network confirms that the received information is information about access request coming from the mobile station, and then completes transferring the current mobile station service together with the kernel exchange network of WCDMA system; the kernel exchange network releases originally allocated resources. It implements the switching from WCDMA system to PHS system and make a mobile station which has WCDMA and PHS transceivers able to smoothly switch from WCDMA system to PHS system.

Description

technical field [0001] The present invention relates to a switching method between a Wideband Code Division Multiple Access (WCDMA) system (hereinafter referred to as WCDMA) and a PHS system (Personal Handyphone System, Personal Handyphone System), especially an execution method for switching between WCDMA and PHS systems . Background technique [0002] With the wide application and rapid development of mobile communication systems, many key technologies in the mobile system are becoming more and more perfect. While realizing the normal communication of users, it is also necessary to consider how to obtain the best performance so that both the system and user equipment can obtain better performance. Nice satisfying effect. [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 the coexistence of WCDMA and PHS will appear. In this case, real...
