Problems solved by technology

However, this method completely relies on the definition of handover relationship and handover statistics in the existing network, and can only evaluate interference within the scope of the defined handover relationship. If the handover definition is wrong or the amount of handover data is small, the result of frequency optimization will be affected, making frequency allocation unreasonable.

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0039] like figure 1 As shown, it is a flowchart of a frequency optimization method based on a measurement report in a specific embodiment of the present invention, and the method includes the following steps:

[0040] Step S11: Obtain the signal strength and sampling points of the main serving cell and the interfering cell;

[0041] From the measurement report information extracted from the IUB interface signaling, the signal strength and sampling points of the main serving cell and the interfering cell are obtained according to the static table of cell basic information.

[0042] The IUB interface is the interface between RNC (Radio Network Controller, that is, radio network controller) and NodeBNode B (the name of the incoming mobile base station of the 3G network), and completes user data transmission, user data and signaling between RNC and...

Abstract

The invention discloses a frequency optimization method based on a measurement report. The method comprises the following steps: establishing an inter-cell interference matrix by extracting measurement report information from IUB (interface between NodeB and RNC) signaling and establishing a telephone traffic model; obtaining a recommended main frequency point allocation scheme and a recommended auxiliary frequency point allocation scheme of the cell through a genetic algorithm; and finally obtaining the recommended frequency point allocation scheme of the cell. Through the method provided by the invention, the perception of a user can be fully reflected, reasonable suggestions are offered to the frequency allocation of the current network, and the real-time performance and rationality of frequency optimization are improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a frequency optimization method based on a measurement report. Background technique [0002] With China Mobile's TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) network construction in full swing, whether it can provide high-quality services will determine whether the TD-SCDMA network can compete in the future. key to success. [0003] TD-SCDMA (hereinafter referred to as TD) network has very few frequency points. In the case of limited frequency resources, co-frequency networking is unavoidable. Co-frequency interference is the main cause of network anomalies. At present, the existing TD frequency point planning generally depends on the topology of the cell and the relationship between neighboring cells. The results output by the planning software are not very referential. There is no com...
