Method for resetting controller of serving wireless network in wireless telecommunication system

Abstract

The method includes operation for transferring from first wireless network controller to second first wireless network controller. The first wireless network controller is allotting radio and network resources to a user device, and the second network controller is going to allot radio and network resources to the user device continuously. The wireless telecomm system contains a core network including multiple service GPRS supporting nodes. The first wireless network controller is coupled to first service GPRS supporting node, and the second wireless network controller is coupled to second service GPRS supporting node. The method executes route switching at GPRS supporting nodes between wireless network controllers and service GPRS supporting nodes. The switching includes two modes: within a service GPRS supporting node, and between service GPRS supporting nodes.

Description

technical field [0001] The present invention relates to a method for resetting a serving radio network controller (Serving Radio Network Controller, SRNC) in a radio telecommunication system (Radio telecommunication system), so as to switch a radio access network (Radio Access Network, RAN) for continuous service A mobile user equipment (User Equipment, UE). And especially the wireless telecommunication system is a Universal Mobile Telecommunications System (UMTS), and the method according to the present invention is a packet switching between a core network (Core Network, CN) and a plurality of wireless access networks Routing (Packet Routing). Background technique [0002] Universal Mobile Telecommunications System (UMTS) is one of the third-generation mobile communication system standards. Its wireless access technology adopts Wideband Code Division Multiple Access (WCDMA), and its core network follows Global System for Mobile Communications / General Packet The structure...

The procedure of the second prior art is substantially the same as that of the first prior art, the difference is that when the RNC 42 entrusts the authority to serve the UE 10 to the RNC 52, the RNC 42 does not suspend at this time, and continues the packet transmission with the UE 10, And these packets are copied to RNC 52, until GGSN 22 updates the packet route from originally passing between SGSN 241 and RNC 42 to passing between SGSN 242 and RNC 52, then the replication of packets is stopped

The third prior art is similar to the second prior art, the difference is that the packet replication of the second prior art is performed in the RNC, and the packet replication of the third prior art is performed in the core network (such as GGSN or SGSN) conduct

Since both the second prior art and the third prior art use packet replication to serve the reset of the radio network controller, additional consumption of network and radio resources is caused
