Method for implementing load equalization in pool district and core network node

Abstract

The present invention provides a method for realizing the load balancing in a pond area, the method comprises that the business request originated by a user is received, and a received core network node of the business request is judged whether meeting the condition of a threshold value of the user migration according to the load information of the core network node in the pond area, if necessary, the user is migrated on the core network node where the load in the pond area is smaller than the load of the core network node of the received business request; if not, the core network node of the received business request processes the business request. Proportionally, the present invention also provides a CN node. The utilization of the technical proposal provided by the present invention can enable to rationalize the load distribution of the various CN nodes in the pond area, to improve the availability of an equipment.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for realizing load balancing in a pool area and a core network (CN, Core Network) node. Background technique [0002] The flexible Iu interface (Iu-Flex) function is a function introduced since 3GPP R5 in the fields of Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access (WCDMA) and Time Division Synchronous Code Division Multiple Access (TD-SCDMA). technology, which supports the intra-domain connection routing function of a base station controller (BSC, Base StationControl) / radio network controller (RNC, Radio Network Controller) to multiple CN nodes. Wherein, the area served by multiple CN nodes is called a pool area, and the multiple CN nodes in the pool area implement load sharing, and the service scope they provide covers the entire pool area. [0003] When the user enters the network for the first time, BSC / RNC calculates the cur...

Problems solved by technology

[0004] However, in the process of implementing the present invention, the inventor found that: because the algorithm on the BSC / RNC is pre-configured, it cannot be adjusted in time. Therefore, when the load of the CN node changes, if the algorithm is still configured according to the BSC / RNC If the algorithm selects the CN node, it will cause the load distribution of the CN node to be unreasonable, and eventually lead to a decline in equipment utilization.
