A method for positioning blind coverage area of ECDMA system

Abstract

The invention discloses a blind area positioning method of WCDMA system, including step A, putting test terminal and device of global positioning system together to carry out road testing; step B, recording uplink / downlink blind area measurement event reported by test terminal and first time information, storing it into first file; step C, recording latitude and longitude information output by the mentioned global positioning system and corresponding second time information, and storing to the second file; step D, relating first and second file by first and second time information, to obtain latitude and longitude information corresponding to mentioned uplink / downlink blind area measure event. The invention can realize accurate and efficient positioning of uplink / downlink blind area, without requirements to testing ability of terminals.

Description

Technical field [0001] The present invention relates to the field of network planning and optimization, and in particular to a method for locating coverage blind areas in a wideband code division multiple access (WCDMA) system. Background technique [0002] After the communication network is completed, there will often be some coverage blind spots or areas where the coverage edge does not reach the coverage edge of the network plan. For the convenience of description, the above areas are collectively referred to as coverage blind spots. The purpose of network optimization is to find the coverage blind area and eliminate the coverage blind area by adjusting the antenna's direction angle, inclination angle, transmission power and other technical means. In the initial stage of WCDMA system network construction, in urban areas, especially dense urban areas with high-rise buildings, coverage blind areas are generally serious. Therefore, how to efficiently and accurately locate coverag...

Problems solved by technology

[0003] Chinese patent application 200610065624.7 discloses a "base station signal generating device for WCDMA system testing and its use method". The base station signal generating device provided by the patent application can realize WCDMA network planning, network optimization and equipment testing, but the detection of coverage blind spots depends on The positioning accuracy of the measurement terminal is low, and it is difficult to achieve the effect of accurately locating the coverage blind area; at the same time, this solution measures the quality of the main frequency of the cell, and this measurement can only reflect the downlink coverage of the cell, and cannot reflect the quality of the cell. The case of uplink coverage

[0004] To sum up, it can be seen that the method of locating the coverage blind area of ​​the WCDMA system in the prior art obviously has inconvenience and defects, so it is necessary to improve it
