Embodiment Construction
[0050] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0051] Such as figure 1 As shown, the specific implementation steps of the present invention are:
[0052] The present invention provides a set of methods for automatic frequency interference evaluation using the interference matrix generated by the MR information captured by the Abis port. MR information is the mobile station measurement report captured by the Abis port, which includes the serving cell where the mobile station is located at the time of measurement, the time slot, the uplink level, the downlink level, the currently used frequency number, and the BCCH frequency of the neighboring cell Number, base station color code BSIC and the level value of the frequency point. According to the MR information, the interference matrix is generated to establish the interference model of the current network, and the genetic algorithm is introduced f...

The invention relates to the technical field of mobile communication network optimization, in particular to an automatic frequency optimization method based on measurement report data, which comprises the following steps: (11) calculating the interference probability of each adjacent region pair with measurement report data; (12) generating a BCCH-class interference matrix according to the interference probability of each adjacent region pair; (13) generating a TCH-class interference array according to the interference probability of each adjacent region pair and the collision probability of TCH; (14) accurately estimating the total interference of a single frequency point; (15) optimizing the BCCH frequency point through a genetic algorithm; and (16) optimizing the TCH frequency point through the genetic algorithm. The automatic frequency optimization method of the invention is a fundamental method for network planning and optimization of the GSM mobile network. Since the frequency optimization is a key link in the GSM network optimization, the invention can effectively reduce the frequency point interference in the system and improve the network capacity and service quality. Therefore, the invention has great significance for network operators.
Description
Technical field [0001] The invention relates to the technical field of mobile communication network optimization, in particular to an automatic frequency optimization method based on measurement report data. Background technique [0002] MR is also called measurement report. In the GSM specification, the collection terminal sends it every 480 milliseconds. It contains the geographic location and wireless environment information of all users on the Internet. The measurement report includes the service cell and the timing advance of the mobile station. Its downlink receiving field strength, as well as the color code, frequency and downlink receiving field strength of up to 6 neighboring cells, these information systems were originally used for power control, handover and other judgment basis, and are also the basis for all current frequency optimization based on MR information data source. [0003] At present, network interference evaluation is mainly based on DT drive test and swee...
