TA re-planning method and system

Abstract

The invention discloses a TA re-planning method and system. The method comprises the steps that current user parameters of cells and user flowing parameters between the cells are obtained; a TA re-planning model is established through the obtained current user parameters of the cells and user flowing parameters between the cells, wherein the target function of the TA re-planning model comprises an updating expenditure minimum function, a paging signaling expenditure minimum function and a re-planning cost minimum function; based on original TA planning information of the cells, the TA re-planning model is resolved, and TA re-planning information of the cells is obtained; and according to the obtained TA re-planning information of the cells, TA re-planning is carried out on the cells. According to the method and system, position zone updating cost, paging cost and reconstruction TA planning cost are ranked as three targets, the mutual contradiction and the restriction of the three targets can be well reflected, a pareto solution set which can well reflect a network environment can be obtained, and the TA re-planning method and system are suitable for a large network.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a TA re-planning method and system. Background technique [0002] In the mobile communication system, because the location area is related to the management of the user's mobility, the terminal equipment is designed with the location area, such as the location area (Location Area) and the routing area (Routing Area) in GSM / UMTS. In order for the core network to only page the terminal in a limited range without paging the entire network, the core network needs to know the approximate location of the mobile terminal in the idle state. TD-LTE, the evolution standard of mobile wireless technology in the 4G era, applies a similar location area concept, which is called a Tracking Area (TA). Similarly, the EPC must manage the registered TAs of the users in the idle state and the connected state, and the users will also change the TA registration information in the EPC wh...
