Embodiment Construction

[0030] Handover Control (HC) is an important part of Radio Resource Management (RRM). In the mobile communication system, after the user terminal is connected to the network in the initial cell, it may need to use the service of the new cell due to various reasons. The handover process in the multi-carrier frequency TDD / CDMA system is to connect the user terminal Handover to a carrier frequency in another suitable sector so that service is not interrupted.

[0031] The detailed process and implementation flow of the handover in the multi-carrier frequency TDD / CDMA system will be specifically described below.

[0032] In a multi-carrier TDD / CDMA system, since there is no pilot channel on the supplementary carrier, the UE cannot directly obtain the strength information of the supplementary carrier, so the pilot strength of the main carrier in each sector must be used as the basis for handover decision. That is, at this time, all measurements on the pilot strength should be base...

Abstract

This invention provides a switch control method in a multi-frequency point system including: a user device gets related measurement configuration parameters to configure lists of local areas, the device reports the measurement result of the local and the adjacent areas, a wireless network controller receives the result to maintain the target area list used in switch, if the user device receives the switch instruction from the controller, it accesses the main carrier instructing said switch order to set up a new wireless connection, said device should send the information of finishing the switch to the controller and works on the main carrier then to be adjusted to the sub-carrier and the user device sends information for the successful switch.

Description

technical field [0001] The present invention relates to the switching control technology in the field of cellular mobile communication, more precisely, it relates to the switching control technology in the TDD / CDMA cellular mobile communication system configured with multiple frequency points sharing common channels. Background technique [0002] In order to meet the increasing demand of mobile users in the next generation digital cellular system, the use of sectorization and multi-carrier technology can reduce the interference in the system and thus increase the capacity of the system. The main advantage of cell sectorization is that inter-symbol interference is suppressed. Compared with non-sectorized cells, under the same number of users, the communication quality of sectorized cells will be improved, or the same system performance will be maintained. In the case of , sectorization can increase the number of users accommodated in the cell. [0003] When a base station wi...
