Planning method for 5G network tracking area

Abstract

The invention relates to a planning method for a 5G network tracking area. The planning method comprises the following steps: acquiring road data information and cell parameters; determining the TA division number according to the road data information and the cell parameters; determining the number of clusters according to the TA division number, and determining the position of an initial cluster center according to the distance between the base station and the road; and performing TA planning by using K-means clustering according to the similarity between the initial cluster center and the base station cell. Road data and base station cell parameters of the to-be-planned area are obtained, and the maximum number of cells capable of being accommodated by the TA is determined. A plurality of cluster centers are preferably selected according to the distance from the cell to the road, clustering is carried out according to the similarity, clusters with the same number as the cluster centers are obtained, each cluster corresponds to one TA, the situation that the base station cells covering the same road are divided into different TAs is avoided, the base station cells with similar geographical density distribution characteristics and service distribution characteristics are clustered into the same TA, geographic features are combined, user service characteristics are considered, a planning result is directly output, and the unreasonable risk of manual division is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communications, and more specifically, to a planning method for 5G network tracking areas. Background technique [0002] With the exponential growth of mobile communication data traffic, the number of terminal devices has increased dramatically and moves frequently, which greatly increases the difficulty of mobility management on the network side, especially user location management. In the 5G network, the network coverage area is artificially divided into multiple user tracking areas (Tracking Area, TA). Wherein, each TA includes a certain number of cells. When a terminal user in the RRC idle state moves within the range of the same TA, there is no need to frequently perform location update reporting operations, and only when the terminal crosses the TA boundary, perform location update operations and generate location update signaling. Therefore, if the TA division is too small, the number of inc...
