Tracing region merging method and tracing region separating method

Abstract

The invention discloses a method of combining tracking area and a method of separating the tracking area; wherein, the method of combining tracking area comprises the following steps: S202, during the observation time, evolution packet center counting the act statistical data of all the user equipment in the managed tracking area; S204, judging whether the time of changing the tracking area of most user equipment is higher that the multiple tracking areas of combined threshold of the tracking area; S206, if it is, the evolution packet center combining the multiple tracking areas. The invention is able to reduce the network source wastage and avoid the unreasonable TA exchange.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly relates to a method for merging tracking areas and a method for separating tracking areas. Background technique [0002] 36300-800 describes that the Long Term Evolution (LTE for short) network consists of an evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN for short) base station (Evolved NodeB, eNB for short) and an evolved packet switching center (Evolved Packet Core, EPC for short), and the network is flat. Wherein, the E-UTRAN includes a set of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2 interface. Both S1 and X2 are logical interfaces. One EPC can manage one or more eNBs, one eNB can also be controlled by multiple EPCs, and one eNB can manage one or more cells. [0003] TR23.882 stipulates that in the LTE system, the radio access network (Radio Access Networ...

Problems solved by technology

[0007] Because the TA is not very accurate when the network is initially configured, there may be mismatches and misconfigurations, resulting in unreasonable TA configuration, and frequent TA updates of UEs in this area, wasting network resources and consuming terminal power;

[0008] Since the TA is fixedly set on the network side, the network cannot self-optimize this parameter during long-term operation, and the TA parameter setting cannot be consistent with the UE behavior mode in the actual network. For a UE with a large mobile range, the UE will perform unnecessary inter-TA handover, and for a UE with a small mobile range, the paging range of the UE is too large, resulting in network redundancy load
