Method and system for implementing automatic load redistributing

Abstract

The invention discloses a method for implementing automatic load reallocation, comprising: when CN node starts unloading, informing RAN node; RAN node sets status corresponding to the CN node according to unloading information carried in the received notice and returns response to the CN node, and when the response the setting result information carried in the response received by the CN node shows success, entering the unloading status. And the invention also discloses a system for implementing automatic load reallocation. By setting unloading start / stop threshold, it automatically starts the unloading course according to the current load status, and besides, by unloading course starting interaction of Iu interfaces, it shortens delay caused by artificial interference and larges reduces maintenance costs of manpower and material resources.

Description

Technical field [0001] The invention relates to load redistribution technology, in particular to a method and system for realizing automatic load redistribution under Iu-Flex networking. Background technique [0002] The third-generation partnership project (3GPP) version 5 (REL5) supports Iu-Flex features, and radio access network (RAN) nodes such as radio network controller (RNC) or base station controller (BSC) can connect to multiple core networks (CN) nodes such as the mobile switching center (MSC) in the circuit switched (CS) domain and the serving GPRS support node (SGSN) in the packet switched (PS) domain. For Iu-Flex (Routing functionality for intra domain connection of RAN nodes to multiple CN nodes), it roughly means "the routing function applied to the connection between a RAN node and multiple CN nodes in the same CN domain." Technicians usually use Iu-Flex directly. The areas covered by several RANs form a pool area. A pool area is usually served by several CN nodes...

Problems solved by technology

[0021] However, since the network management system on the CN side and the network management system on the RAN side are usually separated and are maintained separately by maintenance personnel from different departments of the operator, when the maintenance personnel on the CN side perform load redistribution, they must notify the maintenance personnel on the RAN side through communication means. This will undoubtedly increase the maintenance cost of manpower and material resources; more importantly, during the collaborative operation process of the maintenance personnel of the CN side network management system and the RAN side network management system, operation errors are likely to occur, which will lead to the failure of the entire load redistribution process , which reduces the quality of load redistribution, introducing serious consequences
