Problems solved by technology

[0005] In terms of the switching mechanism of the system itself, there is a big difference between the WCDMA system and the PHS system. In the process of realizing the complete inter-system switching between WCDMA and PHS, the switching from the PHS system to the WCDMA system is an indispensable link. There is currently no solution to this switching problem

Embodiment Construction

[0031] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The basic process of the method of the present invention is as follows: figure 1 shown, from figure 1 As can be seen:

[0033] (1) In the PHS system, after measurement and judgment, if it is considered that an intersystem handover from PHS to WCDMA needs to be initiated, the mobile station uses another transceiver to send an RRC (Radio Resource Control) connection establishment request message to the WCDMA system Access to WCDMA network, RNC (Radio Network Controller, Radio Network Controller) sends RRC connection establishment message to mobile station immediately, and mobile station establishes RRC connection with WCDMA network (ie step 101). During this process, the connection between the original transceiver and the PHS system is not interrupted, and normal communication can be performed.

[0034] (2) Through the message interactio...

Abstract

The invention discloses an executing method of switching from PHS system to WCDMA system, including the steps: by measuring and judgment, when it is necessary to switch from PHS system to WCDMA system, the mobile station transmits access request information to WCDMA system for switching; when receives the information of non-access layer, if judging it is switching information from PHS system, the kernel of WCDMA allocates resources to the mobile station to build wireless connection and wireless supporting; stopping communication in PHS system, releasing the resources in PHS system which are originally occupied by the mobile station, and then the mobile station starts communication in WCDMA system. It can effectively implement the mobile station switching processing from PHS system to WCDMA system.

Description

technical field [0001] The invention relates to a switching method between a WCDMA (Wideband Code Division Multiple Access) system and a PHS system (Personal Handy phone System), especially a switching execution method between the PHS system and the WCDMA system. 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, which is both for the system and the user equipment. better 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 common in China, so there will be a situation where WCDMA and PHS coexist. In this case, realizing the smooth transition from PHS to WCDMA is expected by both operators and communic...
