Embodiment Construction

[0060] The core of the present invention is to provide a method for implementing RRC signaling integrity protection involving SRNS relocation. Specifically, TRNC sends messages to UE by adding offset SN and corresponding HFN. The implementation method can be that the SRNC adds an offset to the SN and sends it to the TRNC, that is, sends the SN+Offset to the TRNC, or the SRNC still sends the SN to the TRNC, and the TRNC updates the SN to SN+Offset. At the same time, adjust the value of HFN according to the flipping situation when SN increases the bias.

[0061] 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 with reference to the accompanying drawings and embodiments.

[0062] Considering that the SRNC needs to send a control message to the UE during the relocation process, and the message can be one or more, for example, if the control message sent by the SRNC is...

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 which adds 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 field of mobile communication technology, in particular to a method, system and wireless radio resource control (RadioResources Control, RRC) signaling integrity protection related to the relocation of the Serving Radio Network Subsystem (SRNS) 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 (UTRAN) through an air interface. UTRAN is composed of a set 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 the network is UE-NodeB-RNC-CN. [0003] Generally, when a UE is connected to a UTRAN, only one RNS serving the UE is involved. At this time, this RNS becomes an SRNS, and ...
