Method and system for obtaining combined interference matrixes of broadcast control channels

Abstract

The invention discloses a method and a system for obtaining combined interference matrixes of broadcast control channels, which are used for obtaining the combined interference matrixes of the broadcast control channels of a plurality of serving cells in a mobile communication network, and the method comprises the following steps: A. obtaining interference matrixes of sweep frequency data of the broadcast control channels of a plurality of serving cells; B. obtaining interference matrixes of measurement reports of the broadcast control channels of a plurality of serving cells; and C. calculating the combined interference matrixes of the broadcast control channels of a plurality of serving cells according to the interference matrixes of the sweep frequency data of the broadcast control channels of a plurality of serving cells and the interference matrixes of the measurement reports of the broadcast control channels of a plurality of serving cells. Therefore, the combined interference matrixes of the broadcast control channels can be obtained, thus representing the interfered condition of the broadcast control channels of the serving cells in the mobile communication network completely and accurately.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for acquiring a joint interference matrix of a broadcast control channel. Background technique [0002] For mobile communication systems, frequency resources are always a precious resource. With the development of business volume, the traffic density in dense urban areas is increasing, and the problem of frequency interference is becoming more and more serious. How to ensure network quality while improving the utilization efficiency of spectrum resources is an important research topic for mobile network operators and equipment manufacturers. In a GSM (Global System for Mobile communications, Global System for Mobile Communications) network, the effect of frequency planning directly affects the perception of network users. There are three main types of frequency planning optimization currently applied to GSM networks: frequency reuse technology based on trad...

Problems solved by technology

The second technology is widely used in current planning tools, but due to the inaccuracy of electronic maps and propagation models, and the prediction based on coverage cannot truly reflect the distribution of user traffic, the obtained frequency planning results cannot maximize Avoid distractions to users

Using the method provided in the above patent application, the interference matrix of the broadcast control channel can be established on the measurement report, but it still cannot obtain good accuracy, and cannot accurately know the communication quality of the broadcast control channel of the serving cell

[0007] In summary, the existing technology for obtaining the interference matrix of the broadcast control channel of the serving cell in the communication network obviously has inconvenience and defects in actual use, so it is necessary to improve it
