Method, apparatus and system for optimizing and updating tracking area
The present invention relates to the field of mobile communication technologies, and discloses a method, an apparatus, and a system for optimizing a tracking area, and a method, an apparatus, and a system for updating a tracking area. The method for optimizing a tracking area includes the following steps: an Operation, Administration and Maintenance entity obtains an optimization threshold, and performs a tracking area optimization according to the optimization threshold. With the present invention, the Operation, Administration and Maintenance entity can optimize the tracking area automatically.
1. A method for an Operation, Administration and Maintenance (OAM) entity in a mobile communication network which is divided into different tracking areas, the OAM is configured with a northbound interface Itf-N or a private interface Itf-S, the OAM exchanges information with other network entities through the northbound interface Itf-N or the private interface Itf-S, wherein the OAM is configured to add a new base station to a tracking area, comprising:
obtaining geographic location information of the new base station through the northbound interface Itf-N or the private interface Itf-S by the OAM, distance from the new base station to a neighboring base station, and paging capacity of tracking areas which are around the new base station; and
adding the new base station to a tracking area with smallest paging capacity according to the geographic location information of the new base station, the distance from the new base station to the neighboring base station, and the paging capacity of the tracking areas which are around the new base station.
