Collocation method, system and device for tracking area lists

Abstract

The invention discloses a collocation method, a system and a device for tracking area lists, and relates to the mobile communication technology. The method comprises the following steps of: analyzing location recorded information recorded by a mobile terminal; confirming a movement direction and a speed of the mobile terminal; confirming the tracking area lists of the mobile terminal according to the movement direction and the speed of the mobile terminal; and sending the tracking area lists to the mobile terminal. When the tracking area lists are allocated by UE (User Equipment), factors, such as a mobile direction of the UE and a movement speed and the like are considered, therefore, the tracking area lists can be reasonably allocated, not only can coverage areas of the tracking area lists be controlled, but also a frequency of a TAU can be reduced, and performances for a network can further be improved.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a tracking area list configuration method, system and device. Background technique [0002] LTE (Long Term Evolution) is the next-generation mobile wireless network of 3GPP (3rd Generation Partnership Project). Compared with the existing 3G network, it has the characteristics of higher bandwidth and lower delay. [0003] The LTE network is an all-IP network. On the wireless side, RNC (Radio Network Controller) and NodeB (base station) are synthesized into a network element eNodeB (evolved base station). The location management of the entire network is also changed from the original location area The management of the routing area has evolved into the management of the TA (Tracking Area, tracking area), and each tracking area is identified by a unique identifier TAI (Tracking Area Identifier, tracking area identifier). Due to the large number of tracking areas in the LTE...

Problems solved by technology

On the one hand, with only two TAIs, MME cannot effectively and accurately determine the direction of UE movement, so the allocated TA List may not be consistent with the direction of UE movement, resulting in unnecessary radio resources during paging consumption, but also increases the frequency of TAU; on the other hand, the MME cannot know the current movement rate of the UE, and cannot determine how many TAs to allocate in the TA List is the most effective, resulting in the allocated TA List being too large or too small
