Abstract

The invention discloses a method and apparatus for confirming a boundary cell of a tracking area. The method comprises the following steps: collecting base station longitude and latitude and network data of each cell in the tracking area TA; generating a Voronoi diagram according to the longitude and latitude; obtaining an initial boundary cell and a candidate boundary cell of the TA based on theVoronoi diagram; performing first evaluation on the network data of the initial boundary cell according to an evaluation model; when the result of the first evaluation does not satisfy the evaluationrequirements, performing second evaluation on the network data of the candidate boundary cell; comparing an optimization amplitude of the result of the second evaluation relative to the result of thefirst evaluation; when the optimization amplitude is greater than a threshold, confirming the candidate boundary cell as the boundary cell of the TA; and when the optimization amplitude is less than or equal to the threshold, confirming the initial boundary cell as the boundary cell of the TA. By adoption of the method and apparatus disclosed by the embodiment, the impact of the TA boundary changeon a network indicator can be accurately evaluated, thereby guiding the accurate designation of the TA boundary and reducing the signaling storm and the paging congestion rate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for confirming border cells of a tracking area. Background technique [0002] With the rapid development of wireless communication technologies, communication services are developing toward improving service quality and user experience. TA (Tracking Area, tracking area) is a concept established by the LTE (Long Term Evolution, long term evolution) system for UE (user equipment, terminal) location management. The TA function is similar to the LA (Location Area, location area) and RA (Routing Area, routing area) of the 3G (3rd-Generation, third-generation mobile communication technology) system. Through the TA information, the core network can know the location of the UE in the idle state, and can page the UE when there is a data service demand. A TA can contain one or more cells, and a cell can only belong to one TA. TA can be identifi...
