Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, specific examples are given below to further describe the present invention in detail.

[0037] The present invention proposes the networking structure and solution of the RNC node disaster recovery system for disaster recovery at the RNC node level. The main idea is: in the RNC node disaster recovery system, at least two RNC node backups are provided. There is a physical connection between the at least two RNCs; when one of the RNCs fails, the backup RNC takes over the NodeBs under the control of the failed RNC, and continues to provide services for users in the coverage area of ​​these NodeBs.

[0038] figure 2 The network structure diagram of the RNC node disaster recovery system provided by the present invention. like figure 2As shown, NodeB1, NodeB2, ..., NodeBn are connected with RNC1 by a solid line, and are connected with RNC2 by a dotted line, which means that e...

Abstract

The present invention discloses radio network controller RNC node disaster held method. Said method includes base station NodeB continuously monitoring connection RNC whether normal, when monitoring linkage interrupt, NodeB try establishing connection with another RNC; NodeB judging connection operation with another RNC whether successful, if then through said another RNC initializing said NodeB and providing service, otherwise NodeB continue try connection until successful connecting to one RNC. The present invention also discloses a RNC node disaster held system, said system including core network, NodeB, at least two RNC, wherein NodeB with each RNC respectively having physical connection, RNC configured with self-physical connection NodeB parameter, NodeB configured with self physical connection RNC transmission configuration.

Description

technical field [0001] The invention relates to wireless network networking technology, in particular to a radio network controller (RNC) node disaster recovery method and system. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) includes the Radio Access Network (RAN) and the Core Network (CN), where the CN handles all voice calls and data connections in the UMTS system, and implements switching and routing functions with external networks. It is divided into circuit switched domain (CS) and packet switched domain (PS). The UMTS Terrestrial Radio Access Network (UTRAN) consists of one or several Radio Network Subsystems (RNS). An RNS consists of an RNC and one or more base stations (NodeB). The interface between RNC and CN is an Iu interface, and the interface between NodeB and RNC is an Iub interface. Within the UTRAN, RNCs are interconnected through an Iur interface, and the Iur between RNCs can be a direct physical connection or a tra...
