Problems solved by technology

[0007] However, if the TA is too large, the system will process a large amount of traffic overhead for the paging channel in all the cells contained in the TA, because the core network cannot know the location of the idle terminal more accurately than the TA, so the arrival The call of the UE will have to generate paging signaling in all cells in the TA where the UE is located

Embodiment Construction

[0026] The LTE system is an evolution of the existing UMTS 3G technology. For network management, one point of LTE is automatic reconfiguration. It consists of two elements: first, the LTE system should continuously collect user statistics and performance testing indicators, and secondly and most importantly, the LTE system should be able to change the network configuration according to the network status so as to adapt to the distribution of users and meet the needs of the network. demand. Preferably, the technical solution provided by this embodiment is applicable to the LTE system, but it is also applicable to other 3G-related concept systems, and will not be repeated here.

[0027] Based on the above requirements, in the embodiment of the present invention, a method for dynamic planning of TA is proposed, that is, because the distribution and mobility model change over time, based on the TA in the initial network planning, the TA must be planned over time. Make revisions ...

Abstract

The invention discloses a method and device for replanning a TA (Tracking Area), which are used for dynamically realizing performance balancing between TAs in a network operating process. In the method, within a planned updating period, the TA plan of the traditional network is actively regulated based on the analysis of user behavior statistical data by using reduction of network total signaling overhead as a target, therefore, the sum of updating signaling overhead and paging signaling overhead of a current user behavior mode based integral network is minimized, furthermore, performance balancing between the TAs is effectively realized, signaling resources in network are saved; and the saved signaling resources can be used in services of new users to enhance the capacity performance of the network and can be used for directly reducing the integral load of the network to improve the reliability of a system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for performing TA re-planning. Background technique [0002] Location management is an important function of cellular networks. In the mobile communication system, the concept of the location area is designed for the terminal equipment, such as the Location Area ( location area) and Routing Area (routing area). Location area settings are used to manage user mobility. For a terminal in an idle state, the core network can know the approximate location of the terminal. If the terminal needs to be found, the core network can page the terminal within a limited area instead of paging in the entire network. [0003] The LTE (Long Term Evolution, long-term evolution) system is based on the evolution of the existing UMTS 3G technology. In the latest SAE (System Architecture Evolution, System Architecture Evolution) protocol 3GPP TS 23.401 v10.0.0, a similar concep...
