Area load control method, system and equipment

Abstract

The invention relates to radio communication field and discloses an area load control method, system and device, which balances the resident loads for the entire network and reduces the possibility of the access blocking. The invention processes a statistics for the quantity of the vacant terminals and balances the vacant terminals according to the quantity of the vacant terminal in the areas. The areas can be the areas of small area level and can be the areas of TA level. The core network device can balance the load for the vacant terminals and the base station can balance the load for the vacant terminals.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to load control technology. Background technique [0002] The Universal Mobile Telecommunications System ("UMTS" for short) is a third-generation mobile communication system that adopts the Wideband Code Division Multiple Access ("WCDMA" for short) air interface technology. [0003] In the UMTS system, in order to facilitate the mobility management of the user equipment (UE) on the network side, the UMTS system divides the network into multiple preset areas in advance during network planning, and each preset area is a Or the area covered by multiple NodeBs (base station nodes). The preset area corresponds to a Location Area (LA) in the Circuit Switching (CS) domain, and corresponds to a Routing Area (LA) in the Packet Switching (PS) domain. Routing Area, referred to as "RA"), LA, and RA can be collectively referred to as Tracking Area (Tracking Area, referred to as "TA"), ind...

Problems solved by technology

[0005] However, the inventors of the present invention have found that currently in UMTS there is only the requirement and implementation of load balancing for UEs in active state, and no implementation scheme for load balancing for UEs in idle state has been proposed.

Regardless of whether it is in the UMTS system, or in the LTE system or other network systems, if the UEs in the idle state camp on a certain cell too concentratedly, it will cause a large camping load on the cell, which will lead to relatively heavy traffic. Many access congestion and access failures will also cause potential cell resource allocation problems
