Method and system for optimizing homogeneous-frequency adjacent-domain configuration

Abstract

The system comprises: radio network controller (RNC) and terminal. The RNC comprises: measurement control unit used for sending down the 1A event report capable of being triggered by the test set in co-frequency measurement control process, and making check after terminal sends the measurement report of the test set to confirm whether or not the cells in test set are the cells in neighboring cell configuration list, and reporting the cells in test set which is not in the list of neighboring cell configuration to the log recording unit; log recording unit used for receiving the cells in test set which is not in the list of neighboring cell configuration from measurement control unit, and recording the content reported by the cell in test set; and log analyzing unit used for analyzing the log content recorded by the log recording unit to get the neighboring cell miss-matched. The invention also reveals a radio network controller (RNC).

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a system and method for optimizing configuration of co-frequency adjacent cells in a wireless mobile communication system. Background technique [0002] In wireless mobile communication systems, especially in mobile communication systems such as CDMA, WCDMA, CDMA2000 and TD-SCDMA, in order to maintain the mobility of communication, inter-cell handover technology is introduced. The handover in the wireless mobile communication system includes same-frequency handover, different-frequency handover and inter-system handover. Among them, intra-frequency handover is the most basic, frequent and important mobility management method, which ensures the mobility of the connection. [0003] In order to ensure co-frequency handover, the network needs to configure co-frequency adjacent cells for each cell. These adjacent cells have a certain coverage overlap with the serving cel...

AI Technical Summary

Problems solved by technology

[0012] In this optimization method, its disadvantage is that the adjacent cells are missing, and the adjacent cells that are missing must be determined through manual drive testing.

The drive test requires dedicated manpower and material resources, and is a high-cost means of neighborhood optimization. At the same time, the results of the drive test can only solve part of the neighborhood optimization problem, and it is difficult to traverse all service areas of wireless mobile networks, especially indoor areas.
