Example Embodiment

[0037] As we all know, the CDMA mobile communication system mainly has several networking schemes such as CDMA2000, WCDMA, TD-SCDMA and LAS-CDMA. The method provided by the present invention for improving the performance of cellular networking by dynamically allocating cell address codes can be used in all CDMA networking solutions, and is particularly suitable for both TD-SCDMA and LAS-CDMA networking solutions. In the following, taking LAS-CDMA as an example, the specific implementation steps of the method of the present invention will be described in detail.

[0038] In the LAS-CDMA system, the LA code is used as the address code of the cell. The basic idea of ​​the present invention is that different LA codes are used to distinguish different cells, and the same cell uses different LA codes to distinguish different radio frames. In this way, the LA code allocated by each cell is changed to be non-fixed, that is to say, the LA code used by each cell is constantly changing with ...

Abstract

This invention discloses a method and device to improve the network performance of CDMA communication system. Its core lies in: using single-frame or multi-frame as the time interval, through sub-synchronization sub-frame sending the allocation information of the small-area/sector address code, to achieve dynamic allocation LA code. That is, the different small-area/sectors are allocated with the different LA codes, and the different frames of the same small-area/sectors are allocated with different LA codes. This method can separate the interference with space and time, significantly reducing the multi-address interference of the small-area/sectors around the border, and effectively solving the difficulty that the system static allocating LA codes for networking.

Description

technical field [0001] The present invention relates to a method for improving the networking performance of a CDMA communication system and its equipment, in particular to a method for improving Code Division Multiple Access (CDMA) mobility by dynamically allocating different cell address codes to the wireless frames of cells / sectors. A communication system networking performance method and equipment thereof belong to the technical field of code division multiple access mobile communication. Background technique [0002] CDMA, also known as code division multiple access mobile communication system, has the advantages of large capacity, multi-user, soft capacity and overcoming system in-band noise interference, compared to FDMA (frequency division multiple access) and TDMA (time division multiple access) systems language has obvious advantages. Because of this, CDMA has become the mainstream multiple access scheme of the ascendant 3G wireless communication system. [0003]...
