Automatic detecting and adding methods and system for base station, terminal and adjacent region relation

Abstract

The invention discloses automatic detecting and adding methods and a system for a base station, a terminal and an adjacent region relation. The methods comprise the following steps of: sending a detection instruction containing preset detection frequency points to the terminal through the base station, then, detecting cells on the preset detection frequency points according to the detection instruction by the terminal, feeding back cell information of the cells to the base station, wherein detected signal intensity of the cell information can meet a preset condition, and the base station can judge whether a new adjacent region exists or not according to the cell information. Namely, when the invention detects an adjacent region, the cell information of all cells which are detected on the detection frequency points are really not sent to the base station, but the cell information of the cells is sent to the base station, wherein the signal intensity of the cell information can meet the preset condition. Therefore, the detected cells can be effectively screened, redundant information in an adjacent region relation allocation process can be greatly reduced, an adjacent region relation maintenance process can be simplified, adjacent region relation maintenance efficiency can be improved, moreover, when the terminal is switched, the adjacent region to be switched can be directly found as soon as possible, and efficiency and a success ratio for terminal switching can be improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a base station, a terminal, an automatic neighbor cell relationship detection and addition method, and an automatic neighbor cell relationship detection and addition system. Background technique [0002] In the E-UTRAN (Evolved Universal Terrestrial Radio Access Network) system, the configuration of the neighbor cell relationship is to ensure that the terminal can switch to the target cell in time when it moves between networks, and avoid Poor and cause dropped calls. Reasonable neighbor relationship configuration can effectively ensure the success rate of network handover and improve the user's network experience. However, in the process of configuring neighbor cell relations, the existing practice is to report all the cell information of the cells detected on the detection frequency point to the base station, but for some cells, the base station does not actually need it,...

Problems solved by technology

However, in the process of configuring neighbor cell relations, the existing practice is to report all the cell information of the cells detected on the detection frequency point to the base station, but for some cells, the base station does not actually need it, but due to the terminal's reporting , the base station will still add it to the neighbor relationship table, resulting in more redundant information in the configured neighbor relationship table

Due to the limitation of the number of records in the neighbor relationship table, when there is a lot of redundant information, reasonable neighbors cannot be added to the neighbor relationship, which affects the efficiency and success rate of network switching and reduces the user experience. satisfaction

[0003] In addition, in the process of configuring the neighbor relationship, it often happens that the correct neighbor relationship is not added to the neighbor relationship, which causes the terminal to fail to complete the cell handover normally when the wireless environment changes during the mobile process and drops out. talk

Especially for scenarios where there are neighboring cells of different systems, the terminal can only detect the signals of neighboring cells in different systems according to the cells of different systems carried in the measurement configuration issued by the base station, but for the cells of different systems not configured by the base station, the terminal cannot actively Discovering and reporting this kind of neighbor cell information, the base station cannot obtain the neighbor cell information existing in the unconfigured heterogeneous system, and cannot complete the automatic addition of the neighbor cell (such as UTRA neighbor cell, CDMA2000 neighbor cell) relationship in other heterogeneous systems , leading to the reasonable neighbor relationship not being added to the neighbor relationship, which in turn leads to handover failure due to unreasonable configuration of the neighbor relationship when the terminal moves in the network, which greatly reduces the satisfaction of the user experience
