Problems solved by technology

The current reporting of drive test neighbor cell information does not involve eNB / RNC selection for information reporting. Obviously, if the eNB / RNC reported by the drive test result is not suitable, effective update of the relevant neighbor cells of the cell cannot be realized.

Abstract

The invention discloses an automatic neighbor cell list maintenance method which comprises the following steps that: user equipment (UE) detects cell information of a UE serving cell and / or neighbor cells of the serving cell according to a drive test signaling, and reports the detection result to a network side; the network side sends the cell information of the neighbor cells of the serving cell to a network node to which the serving cell belongs; or, the network side sends the cell information of the serving cell to network nodes to which the neighbor cells of the reported serving cell belong; and the network nodes receiving the serving cell information or the neighbor cell information carries out local neighbor cell maintenance. Meanwhile, the invention discloses an automatic neighbor cell list maintenance system for realizing the method. According to the invention, the manpower is saved, and the cost for neighbor cell maintenance is saved as well. In addition, the cell information detection realized through automatic drive test enables the cell information acquisition to be accurate and timely, and neighbor cell lists maintained according to the cell information are rather high in accuracy rate.

Description

technical field [0001] The invention relates to a technology for maintaining a neighbor list of a network element on a network side, in particular to a method and system for automatically maintaining a neighbor list. Background technique [0002] In the communication system, in order to reduce the cost of network construction and operation, the traditional drive test is to manually test the areas that need to be monitored and optimized. In the evolution system based on the next generation network, the dependence on the traditional drive test and It is necessary to use more intelligent network optimization tools. Therefore, it is very beneficial to automatically realize the collection of measurement information of drive test terminals (that is, user equipment) and minimize the need for manual drive test. On the other hand, using the test results of user equipment (UE, User Equipment) can automatically optimize the network and have a comprehensive understanding of network oper...
