Method, system and device for accessing into core network nodes

Abstract

The embodiment of the invention relates to a method, system and device for accessing into core network nodes. The method comprises the following steps: selecting a core network node into which an access point is accessed according to the pre-established mapping relationship of the access point and the core network node when a service request from the access point is received; and sending the service request to the selected core network node. The embodiment of the invention provides possibility for user equipment to select one of multiple core network nodes to access, and does not require the core network node to support an Iu-flex function, and if the existing core network node does not support the Iu-flex function, by adopting the technical scheme of the embodiment of the invention, functional upgrade needs not to be performed; and the core network also needs not to be changed, thus from the whole system, the technical scheme is more practical and simple, lowers the influence to the core network, and obviously improves the access flexibility of the multiple core network nodes.

Description

Access method and system for core network node and access device technical field The present invention relates to communication technology, in particular to a core network node access method and system and access equipment. Background technique The flexible Iu interface (Iu-Flex) technology is a new technology introduced in the Third Generation Partnership Project (Third Generation Partnership, referred to as 3GPP), which supports a radio network controller (Radio Network Controller, referred to as RNC) to multiple core networks ( CoreNetwork, referred to as CN) node's intra-domain connection routing function. Among them, the area served by multiple CN nodes is called a pool area (Pool-Area), and multiple CN nodes in the pool area implement load sharing. These CN nodes use Network Resource Identifier (NRI for short) in the pool area ) to uniquely identify. When a user equipment (UserEquipment, referred to as UE) initiates an access request to a pool domain of the core n...
