Problems solved by technology

These problems lead to the deterioration of wireless signal quality, serious interference of levels 5 to 7, and significant decline in user perception
[0003] The traditional hexagonal cell cluster analysis method for interference and coverage can no longer meet the increasingly complex wireless network analysis requirements, and the conventional drive test and frequency sweep test methods cannot accurately locate the specific interfered frequency points and the degree of interference in the serving cell As well as the location of the interference source cell, this has become a key technical bottleneck for further fine-tuning the current wireless network

Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] see figure 1 , the embodiment of the present invention provides a method for signal optimization based on the carrier-to-interference ratio C / I, which specifically includes:

[0069] S101: Carry out drive test frequency sweep for the selected road section with poor reception quality, record the drive test frequency sweep data in real time, and calculate the carrier-to-interference ratio of each time slot according to the drive test frequency sweep data.

[0070] For the selection of road sections with poor reception quality, All-RxQual Sub can be screened from the test data of ordinary TEMS test equipment or automatic drive test equipment (received signal quality level, that is, signal quality level. Test the signal quality leve...

Abstract

The invention discloses a method and system for positioning and processing interference and relates to the field of mobile communication technologies. According to the method and system, a novel signal optimization technology is provided, high-precision service channel time slot frequency sweep data are obtained through precise calculation, electrical levels and carrier-to-interference ratios (C-to-I) of all time slots of all carrier frequency of all cells of problematic router sections so that the interference can be accurately positioned, detailed causes are analyzed according to the positioning of the interference, optimization adjustment is performed, and therefore the overall performance of a cellular wireless network is fundamentally improved. Furthermore, according to the method and system, values of the C / I can be combined for judging the degree of the interference more accurately, and effective reference is provided for signal analyzing and adjusting.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an interference location and processing method and system. Background technique [0002] With the rapid growth of mobile services, the wireless network load is increasing day by day, and GSM900, DCS1800, and EGSM frequency bands have been put into large-scale applications one after another. While the distance between the base stations of the cellular wireless network is continuously shrinking, the number of high-carrier configuration sites is also increasing rapidly, and the frequency reuse density is continuously increasing. At present, the GSM wireless network of China Mobile Group generally has problems such as excessive overlapping coverage, serious cross-region coverage, a sharp increase in the probability of co-adjacent channel interference, and a significant increase in the noise floor of the wireless network system. These problems lead to the deterioration o...
