System and analysis method of TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) wireless network based on geographical position coverage effect

Abstract

The invention relates to a system and an analysis method of a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) wireless network based on a geographical position coverage effect. The system comprises a data management module which is connected with a radio network controller (RNC) through an operation maintenance interface, an analysis knowledge base module through an internal message interface and an analysis calculation module through the internal message interface as well as respectively connected with a client end and drive test data through an interface adaptor, and a file reading interface of the data management module can be also connected with an input file. The analysis method comprises the following steps of: 1. coverage strength analysis; 2. cell coverage analysis; 3. pilot frequency pollution analysis; and 4. street corner effect analysis. The invention has the characteristics of requiring no special test device, having zero cost, filling up an indoor signal test blank and saving manpower call expenditure of drive test vehicles.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a system and analysis method for coverage effect of a TD-SCDMA wireless network based on geographic location. Background technique [0002] In the process of network operation and maintenance, the wireless environment and equipment conditions are constantly changing. For example: the construction of new buildings leads to cell coverage gaps and changes in the relationship between neighboring cells; the demolition of old buildings leads to enhanced interference between cells and changes in the relationship between neighboring cells; population flow leads to changes in traffic, resulting in idle or tight resources ; Call loss caused by unknown interference or device abnormality, etc. In order to enable the network to dynamically adapt to changes in the environment, quickly determine network abnormalities, and then point out the direction for network adju...

Problems solved by technology

[0004] However, the drive test method consumes a lot of time, manpower, and test costs, and the test cannot traverse all areas. The sampling points obtained in the drive test mainly come from the test UE, the cell under test, and the test time. The information and data of the sample points obtained are not Comprehensive, does not have statistical significance, and cannot reflect the coverage effect of the entire network based on geographic location

[0005] In addition, the sampling method of the sampling test has certain requirements on the number of users and user distribution characteristics. If it is not suitable, it will lead to deviation
