Abstract

The invention relates to a region switch method based on time-division double system, which comprises: A, user device, according to the test control message that set by the wireless network controller, tests the received pilot signal channels of local region and nearby region, and reports the tested result to the wireless network controller; B, wireless network controller judges if the switched target region has the useful resource with different time slot to the former region; if it has, sending region switch command to the user device, and distributing useful resource in the target region, and sending the service load data of user device to the former region and target region; C, said user device receives the switch command, according to the distributed useful resource, communicates with the former and target regions at the same time and the same frame. The invention also provides a relative user device, which comprises a testing unit and a switch unit. The invention can reduce the communication failure, to improve system property.

Description

technical field

[0001] The present invention relates to the switching technology of mobile communication technology, more specifically, the present invention relates to a cell switching method based on time division duplex system. Background technique

[0002] At present, mobile communication has been developed to the third generation of mobile communication 3G. TD-SCDMA is one of the three main standards of the third generation mobile communication approved by the International Telecommunication Union (ITU, International Telecommunication Union) in May 2000 and by 3GPP in March 2001. As a 3G standard for time division multiplexing, Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) is regarded as a low chip rate (1.28MCps, 1.28 megachips / second) in the ITU standard Time division multiplexing technical scheme.

[0003] At present, in the cellular mobile communication system, switching is essential...
