Embodiment Construction

[0032] In FIG. 9 , the present invention discloses a method for reconfiguring the main carrier frequency in the case of multi-carrier cell configuration. NODE B finds that the channel responsible for the main carrier frequency fails, and then sends a message to RNC; RNC judges whether it is necessary to initiate the main In the reconfiguration process, the base station implements reconfiguration of primary and secondary carrier frequencies.

[0033] In the embodiment of the present invention, the following three aspects are firstly described: the reporting method of the failure of the main carrier frequency; the reconfiguration process of the main carrier frequency; the specific implementation method of preempting the auxiliary carrier frequency of the base station.

[0034] Firstly, there are two methods for reporting the failure of the main carrier frequency in the present invention. One is to directly use the existing resource status reporting and indication process in the...

Abstract

This invention discloses a method of reshuffling the master carrier frequency in multiply carrier wave area, which comprises the following steps: a) the node B find that the channel which charges the master frequency out of work, sending the notice to the radio network controller; b) the radio network controller will decide whether opening the master carrier frequency reshuffling procedure, if it is, go to the next step; c) opening the master carrier frequency reshuffling procedure, then the base station realize the master and stand-by carrier frequency reshuffling. By said method, the mobile terminal can get system information and other allocation information when the master carrier frequency out of work in the TD-SCDMA agreement standard.

Description

technical field [0001] The invention relates to a method for realizing coverage of multi-carrier cells in the field of mobile communication, in particular to a method for reconfiguring main carrier frequencies in multi-carrier cells. Background technique [0002] For mobile communication systems, the expansion of system capacity is a problem that manufacturers need to consider. Especially compared with WCDMA system, the capacity of TD-SCDMA system is relatively low at present. In order to increase the system capacity, it is undoubtedly an important means for TD-SCDMA system to increase the system capacity by carrying out multi-carrier frequency coverage in the same sector / cell. [0003] In order to reduce the interference of broadcast channels between carriers and improve system efficiency, in the case of multiple carrier frequencies, pilot and broadcast information are only sent on one carrier frequency of the cell / sector, and multiple frequency points use one common broad...
