Method, system and related functional entities for realizing load balancing in pool area

Abstract

The invention discloses a method, a system and related functional entities for realizing load balancing in a pool area, thus speed and effectiveness for realizing load balancing in the pool area can be improved, and network load and influence of processing capacity on network nodes can be reduced. The method for realizing the load balancing in the pool area comprises the following steps: determining a load balancing index value in the pool area in accordance with load information of each network node in the pool area; when the determined load balancing index value qualifies the set load immigration start conditions, determining a source network node for executing the load immigration and characteristic information on terminals to be immigrated in accordance with the load information of each network node; and within the set load immigration period, immigrating the mobile terminals complying with the characteristic information to a destination network node by source network node control.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and related functional entities for realizing load balancing in regional pools. Background technique [0002] 3GPP (3rd Generation Partnership Project, the third generation mobile communication standardization organization) introduced the concept of Pool Area (regional pool) in R5 (Release 5, version 5), and the regional pool is essentially composed of multiple network nodes of the same type The resource pool of each network node in the same area pool can improve the utilization efficiency of equipment through load sharing. According to the type of network nodes in the area pool, the area pool can be divided into: MSC (Mobile SwitchCenter, mobile switching center) pool composed of CN (Core Network, core network) nodes, SGSN (Serving GPRS Support Node, serving GPRS support node; GPRS: General Packet Radio Service, general packet radio service...

AI Technical Summary

Problems solved by technology

On the one hand, it increases the network load and reduces the processing capacity of network nodes; on the other hand, because each time a service initiated by a mobile terminal is received, it is necessary to judge whether the load migration condition is met, making the speed of load balancing slow

In addition, mobile terminals newly entering the regional pool may be assigned to a network node with a higher load first, and then migrate from the network node to a network node with a lower load, thereby further reducing the speed of load balancing
