Distribution type data storage processing method in UTRAN cooperation paging

Abstract

The invention relates to a distributed data storage processing method in UTRAN coordinated calling, applied to UTRAN coordinated calling in radio network control (RNC) system, and including: A) dividing RNC system into plural relatively independent processing subsystems, establishing a data storage region in each processing subsystem; B) as a user equipment accesses to a processing subsystem of the RNC, adopting distributed storage algorithm to store data record cells of the user equipment into a corresponding data storage region; C) as kernel network initiates UTRAN coordinated calling, some processing subprogram of the RNC obtains the property parameters of the called user equipment by calling information and adopts the distributed storage algorithm to locate the data storage region where the data record cells of the user equipment to read the data record cells. The method can effectively improve the whole performance of UTRAN coordinated calling of RNC system.

Description

technical field [0001] The invention relates to a radio network control system (RNC), in particular to a data storage method of RNC user access equipment in UTRAN (Universal Mobile Communication System Terrestrial Radio Access Network) cooperative paging. Background technique [0002] WCDMA (Wideband Code Division Multiple Access), as an open standard, mainly consists of UE (User Equipment), UTRAN and CN (Core Network). Cooperative paging (see figure 1 ), the RRC (Radio Resource Control) connection has been established, the UE connection mode is CELL_DCH or CELL_FACH, and there are two CN domains, followed by the following description: [0003] The CN initiates a RANAP (Radio Access Network Application Protocol) paging message to page the UE, and the message parameters include: CN identifier, permanent UE identity, temporary UE identity (optional), paging reason, etc. [0004] SRNC (Serving Radio Network Controller) sends RRC paging type 2 message. [0005] The RNC receiv...

AI Technical Summary

Problems solved by technology

[0019] It is easy to cause blockage and message storm during the access process;

[0020] Once the single board storing the data storage area fails, all UTRAN cooperative paging will fail

[0021] Therefore, in terms of system stability, reliability and scalability, the centralized data storage method is a bottleneck that limits the overall performance of the system.
