Method, terminal, base station and system capable of realizing automatic neighbor relation establishment

Abstract

The invention discloses a method capable of realizing automatic neighbor relation establishment. When the cause of triggering re-establishment is determined to be wireless linkage failure, whether a cell global identification CGI of a source cell is consistent with CGI of a selected cell for re-establishment is contrasted, if not consistent, a re-establishment request message is added with the CGI of the source cell while being sent to the network side, if yes, and an unsuccessfully-reported CGI exists, the re-establishment request message is added with the unsuccessfully-reported CGI while being sent to the network side, and re-establishment of the network side is initiated through the re-establishment request message. The invention further discloses a terminal, a base station and a system capable of realizing automatic neighbor relation establishment. Through the method, the terminal, the base station and the system, the ANR function can be realized through adding the CGI to the re-establishment request message, the ANR function in a present protocol can be effectively supplemented, the network switching success rate is improved, the call drop rate is reduced, and integral network performance is improved.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method, terminal, base station and system for realizing automatic neighbor cell relationship establishment. Background technique [0002] In a wireless communication system, in order to reduce the operator's burden of manually managing the neighbor relationship, the operator introduces an Automatic Neighbor Relation (ANR, Automatic Neighbor Relation) function. The ANR function manages the neighbor relationship list. In the ANR function, there are both the neighbor detection function and the neighbor deletion function. Among them, the neighbor detection function is used to find the neighbor and add the neighbor to the neighbor relationship list. , the neighbor cell deletion function is used to delete outdated neighbor cell relationships; the neighbor cell deletion function is an internal behavior of the base station, and the neighbor cell detection function requires the...

AI Technical Summary

Problems solved by technology

[0004] 1) The UE needs to enter the idle state to read the broadcast message of the target cell, and then obtain the CGI information. However, if the UE does not support the function of entering the idle state, or the UE cannot enter the idle state due to service restrictions, the acquisition of the CGI cannot be completed, and the ANR function can not complete;

[0005] 2) If the UE completes the acquisition of CGI, but fails to report successfully due to radio link problems during the reporting process, the ANR function cannot be completed

[0006] 3) There are also some reasons that may cause the ANR function to fail, such as: configuration problems

[0007] Due to the existence of the above problems, the ANR function cannot be completed, so that the automatic neighbor relationship cannot be established. If there is no neighbor relationship, the UE cannot perform handover, nor can it achieve coordination or elimination of neighbor interference. In this case, the UE generally re-establishment will occur
