Problems solved by technology

[0017] In practical application, the above scheme has the following problems: that is, it lacks the flexibility to deal with sudden failures
Once the main control subsystem fails, even if other subsystems do not fail, it will cause a large number of call losses in the entire system
[0018] The main reason for this situation is that the main control subsystem is pre-designated statically and cannot be automatically and dynamically adjusted according to the actual situation. After the main control subsystem recovers, sending a RESET message to CN will affect the business of other normal working subsystems

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] In general, the principle of the present invention is: after the RNC is powered on, the first subsystem that completes the initialization work and enters the ready state is designated as the main control subsystem, and the main control subsystem completes the reset process and communicates with the CN interaction. Moreover, during the operation of the RNC system, when the non-master subsystem detects that the master subsystem fails, the subsystem that first enters the ready state among the non-master subsystems is designated as the new master subsystem. Therefore, when the original main control subsystem recovers, the reset process will not be started, which avoids problems such as call loss caused by the reset.

[0042] In other words, the present inventi...

Abstract

The method is used to avoid service interruption and call loss in the reset process of the other sub-systems in RNC caused by statically appointing main control sub-system, and comprises: selecting a sub-system completing initiation and already entering a standby state as the main control sub-system to implement the reset process and the interaction with CN; in the working process of RNC, if the non control sub-system detects a failure in the main control sub-system, one of non sub-systems, which is firstly into a standby state, is appointed as new control sub-system.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a reset technology in a Radio Network Controller (Radio Network Controller, "RNC") using a distributed management system. Background technique [0002] In recent years, the global mobile communication technology has developed rapidly, and the third generation mobile communication (3rdGeneration, referred to as "3G") is an inevitable trend of development. The International Telecommunication Union (International Telecommunication Union, referred to as "ITU") has specified five terrestrial wireless technologies for 3G, among which Wideband Code Division Multiple Access (WCDMA for short), Code Division Multiple Access 2000 (Code Division Multiple Access) Access 2000, referred to as "CDMA2000") and time division synchronous code division multiple access (Time Division Synchronous Code Division Multiple Access, referred to as "TD-SCDMA") are three mainstream technologies.
