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] In the traditional method of analyzing interference and coverage of regular hexagonal cell clusters, the carrier-to-interference ratio C / I cannot be accurately calculated, and it is only a rough estimate, resulting in large errors in the process of signal optimization and adjustment, sometimes even Adjustment errors are caused, which greatly limits the scope and degree of existing signal optimization adjustments. Therefore, existing signal detection solutions cannot meet the increasingly complex wireless network analysis requirements, and conventional methods based on existing signal detection technologies The carrier-to-interference ratio (the ratio of the carrier power to the interference signal), that is, the carrier-to-interference ratio C / I, cannot be accurately calculated by means of measurement and frequency sweep testing. This has become a key technical bottleneck for the further fine-tuning of the current wireless network.

Embodiment Construction

[0098] 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.

[0099] see figure 1 , an embodiment of the present invention provides a method for processing an interference signal, which specifically includes:

[0100] S101: Determine the boundary and center point of each time slot in each frame period.

[0101] Since the boundaries and center points of the frame period and the slot period are only roughly estimated, there are large errors in the measurement of various parameters in the signal detection, and even many parameters cannot be calculated, so that the scope and degree of existing signal detection are limited. Therefore, as a preference, in the embodiment of the present invention, firstly, the boundaries and center points of each time slot in each frame period are accurately determined,...

Abstract

The invention discloses a method and system for processing interference signals and relates to the field of mobile communication technologies. The method includes the steps that boundaries and central points of all time slots of all frame periods are determined; aiming at one frequency point, service free time slots in the frequency point are calculated; the average background noise of all the service free time slots in the frequency point is calculated; according to the average background noise, whether background noise interference signals exist or not is judged, and if yes, frequency is adjusted. In comparison with the mode that in the prior art, whether the background noise exists or not is evaluated according to experience, the method and system can accurately calculate a value of the average background noise, so that frequency reuse conditions of all frequency points is accurately reflected, and reasonable adjustment is accurately performed on parts with high frequency reuse density, therefore, network optimization is achieved, and the overall performance of a cellular wireless network is fundamentally improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an interference signal 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...
