Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: when a working RNC fails, managers need to manually configure a large amount of data on the backup RNC, and perform transmission adjustments at the same time, so the network recovery Long time, low network reliability

Embodiment Construction

[0016] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments:

[0017] The structure of an RNC backup system according to the embodiment of the present invention is shown in Fig. 2, which includes CN21, backup RNC22, working RNC23 and base station 24; where CN21 and backup RNC22 can be connected to multiple working RNCs at the same time; base station 24 is working RNC23 Managed base stations, working RNC23 can manage multiple base stations at the same time.

[0018] CN21 is connected to backup RNC22 and working RNC23 through Iu interface, backup RNC22 is connected to working RNC23 through Iur interface, and base station 24 is connected to backup RNC22 and working RNC23 respectively. The base station 24 provides 2 sets of Iub interfaces (the physical layer and the link layer can be separated; it can also be shared by the physical layer, while the link layer is separated): a set of...

Abstract

The utility model discloses a processing method for RNC faults, which comprises the following steps: the base station managed by working RNC is respectively connected with a backup RNC and the working RNC, and when the working RNC fails, the base station is switched under the management of the backup RNC; a core network is connected with the backup RNC and the working RNC respectively, and when the working RNC fails, the core network send the message, which is originally intended for the working RNC , to the backup RNC for processing instead. The utility model also discloses an RNC backup system and an RNC. The utility model can automatically switch the failed RNC operations to the backup RNC in case that the working RNC fails, thus greatly reducing the recovery time of the network and enhancing the reliability of the network.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a fault processing method, system and device of a wireless network controller. Background technique [0002] With the rapid development of wireless communication technology, UMTS (Universal Mobile Telecommunications System) has been widely used. UMTS includes RAN (Radio Access Network, radio access network) and CN (Core Network, core network). Among them, RAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in UMTS, and implements switching and routing functions with external networks. CN is logically divided into CS (Circuit Switched Domain, circuit switched domain) and PS (Packet Switched Domain, packet switched domain). UTRAN (UMTS Territorial Radio Access Network, UMTS Territorial Radio Access Network), CN and UE (User Equipment) constitute the entire UMTS. UTRAN includes one or more RNS (Radio Netw...
