Embodiment Construction

[0058] The core of the present invention is to provide a method for realizing RRC signaling integrity protection related to SRNS relocation. Specifically, TRNC sends messages to UE by adding SN with offset (Offset) and corresponding HFN. The implementation method may be that SRNC adds an offset to SN and sends it to TRNC, that is, sends SN+Offset to TRNC, or SRNC still sends SN to TRNC, and TRNC updates SN to SN+Offset. At the same time, the value of HFN is adjusted accordingly according to the reversal situation when SN increases the offset.

[0059] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] Considering that the SRNC will send a control message to the UE during the relocation process, and this message can be one or more, for example, due to the repeated transmission caused by the l...

Abstract

The invention discloses a method relating to the relocation of SRNS for realizing the integrity protection of RRC signaling. TRNC sends message to UE by adopting the serial number which is added with bias and the corresponding superframe number. To be more specific, the SRNC adds bias to the stored serial number and modifies the superframe number; the serial number and the superframe number are sent to the TRNC which sends message to a user terminal by the received serial number and the superframe number; or the SRNC sends the reserved serial number and the superframe number to the TRNC whichadds bias to the serial number and modifies the superframe number; messages are sent to a user terminal by the serial number and the superframe number. The invention also discloses a system relating to the relocation of the SRNS for realizing the integrity protection of RRC signaling and a radio network controller. The invention can realize the sameness of the user terminal as the serial number and the superframe number of the TRNC, thereby ensuring the realization of the integrity protection in the process of the relocation of the SRNS, more particularly, the situation that the SRNC excessively sends information in the process of relocation, and further reducing words dropping.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and wireless communication system for realizing radio resource control (Radio Resources Control, RRC) signaling integrity protection related to Serving Radio Network Subsystem (Serving Radio Network Subsystem, SRNS) relocation. network controller. Background technique [0002] The basic structure of Universal Mobile Telecommunication System (UMTS) is as follows: figure 1 shown. In UMTS, a user terminal (User Equipment, UE) accesses a UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, UTRAN) through an air interface. UTRAN is composed of a group of radio network subsystems (Radio Network Subsystem, RNS). Each RNS includes a radio network controller (Radio Network Controller, RNC) and one or more base stations (NodeB), and the connection of the UE to access the network is UE-NodeB-RNC-CN. [0003] Usually, when a ...
