Embodiment Construction

[0034] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0035] Such as figure 1 As shown, it is a flowchart of a method for determining an interference source in an embodiment of the present invention, and its specific processing process is as follows:

[0036] Step 11: Obtain the received signal code power (RSCP, Received Signal Code Power) and interference signal code power (ISCP, Interference Signal Code Power) of the uplink time slot corresponding to each user terminal included in the target cell;

[0037] In the embodiment of the present invention, if the interference source of the cell A needs to be determined, the cell A is the target cell.

[0038] For the uplink time slot corresponding to each user terminal included in the target cell, the RSCP of the time slot is t...

Abstract

The invention discloses a method and device for determining an interference source. The method comprises the following steps of: firstly, obtaining an RSCP (Received Signal Code Power) and an ISCP (Interference on Signal Code Power) of an uplink time slot, which respectively correspond to each subscriber terminal and are contained in a target cell; then, determining the interferences of adjacent cells on the target cell and the interference in the cell according to the obtained RSCP and the ISCP of the uplink time slot, which respectively correspond to each subscriber terminal; and then determining the interference source in the target cell according to the determined interferences of adjacent cells and the interference in the cell. By adopting the technical scheme of the invention, the condition whether network optimization on a communication system is performed or not can not be determined because the interference source of each cell in a communication system can not be determined in the prior art, such problem can be solved in the invention.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for determining an interference source. Background technique [0002] With the continuous development of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system construction, the improvement of system performance has become a key task in network optimization. Interference has a great impact on the operation of TD-SCDMA system The impact of performance is relatively large, which may lead to a higher call drop rate, and may also reduce the coverage of the TD-SCDMA system. Therefore, overcoming interference in the TD-SCDMA system has become an important aspect of network optimization. [0003] The interference of the TD-SCDMA system is mainly the multiple access interference caused by code division multiple access. The multiple access interference can be divided into intra-cell inte...
