Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and system for signal monitoring and optimization. Background technique [0002] In the prior art, a traditional frequency sweeper is usually used to measure mobile communication signals to obtain frequency sweep data, which is an important basis for evaluating and optimizing communication network conditions. The frequency sweep data measured by the traditional frequency scanner can reflect the signal coverage, and is not limited by manufacturers, equipment, and parameters; the sweep frequency test does not occupy communication system resources like business tests, and the test is simple, which is the current wireless network One of the important technical means of analysis. [0003] However, the traditional frequency scanner can only measure the wireless signal coverage of the BCCH frequency point, that is, it can measure the reception level and C / I meas...

[0003] However, the traditional frequency scanner can only measure the wireless signal coverage status of the BCCH frequency point, that is, the receiving level and C/I measurement of the BCCH frequency point can be measured, and at the same time, the GPS position information and measurement time information can be obtained. The traditional frequency scanning technology cannot Effectively test the parameters related to TCH frequency points other than BCCH frequency points. In the prior art, the frequency sweep test of BCCH frequency points is usually used to perform approximate equivalent analysis on the TCH frequency points of the same cell. Specifically:

[0004] 1. The traditional frequency scanner can only measure the level of the BCCH frequency point, and cannot measure the receiving level, noise floor and C/I of all carrier frequencies including the TCH frequency point

[0005] 2. The traditional frequency scanner can only measure and decode the BCCH channel. The BCCH frequency point is full-power transmission, which is different from the TCH frequency point; for the
