Embodiment
The flow chart of the signaling optimization processing method embodiment that Fig. 1 provides for the embodiment of the present invention, as shown in Figure 1, the method comprises:
When user terminal moves without business, usually be in the RRC Idle state, when user terminal need to carry out the transmission of data or receive, need to carry out the RRC Signalling exchange with network side and make and self could carry out transfer of data with network side after the RRC Idle state is transformed into the RRC connected state.Fig. 2 is that UE is transformed into the signaling process figure of RRC connected state from the RRC Idle state, and as shown in Figure 2, signaling process is specially:
Step 3, the RRC connection is set up request process from sending RRC connection foundation request (RRCConnection Request) message, eNodeB receives that the backward UE of RRC Connection Request that UE sends sends RRC connection configuration (RRC Connection Setup) message, this message comprises for UE sets up Signaling Radio Bearer SRB1(Signaling Radio Bearer1) the carrying configuration information, it should be noted that, solve (Contention Resolution) if having this moment a plurality of UE request services, eNodeB also need send conflict.UE carries out radio-resource-configuration according to the information in RRC Connection Setup, after configuration is completed, UE sends RRC connection configuration to network side and completes (RRC Connection Setup Complete) message, at this moment, UE only has SRB1 to set up, for SRB2 and Data Radio Bearer (Data Radio Bearer, DRB), UE only just can set up these carryings after safety is activated.
Step 4; eNodeB is after message is completed in reception RRC connection configuration; send safe mode command (Security Mode Command) message to UE; this message comprises makes UE activate safe mode security configuration information used; UE draws various keys according to Security Mode Command message, and the configuration bottom is with the algorithm of indicating and key is encrypted and integrity protection.After the safe activation process was completed, UE can will encrypt all message that are used for reception afterwards and send.UE sends safe mode to eNodeB and completes (Security Mode Complete) message after completing security configuration.
step 5, eNodeB need not by the time, and UE sends Security Mode Complete message, just can send the RRC connection and reshuffle (RRC Connection Reconfiguration) message, this message comprises be used to UE is set up and the SRB2 of eNodeB and the carrying configuration information of DRB carrying, because the foundation of SRB2 and DRB carrying needs UE first to activate integrity protection and encipherment protection, therefore, connecting reconfiguration message according to RRC after UE safe activation process is completed sets up SRB2 and be connected backward eNodeB with DRB and send the RRC connection and reshuffle and complete (RRC Connection Reconfiguration Complete) message.
After completing above all signaling processes, UE just can send or receive user face data.Prior art is after completing transfer of data with network side, after eNodeB discharges the RRC connection, user terminal can come back to the RRC Idle state again, to reduce user terminal energy consumption and taking Radio Resource, until user terminal has the demand of communication interaction again, again carry out the RRC Signalling exchange according to signaling process shown in Figure 2 and network side and make and self be transformed into the RRC connected state from the RRC Idle state.Obviously, carry out frequently the RRC connection and set up process, can bring larger signaling traffic load to network, when the terminal in network is numerous, even may produce the signaling storm, cause more to seriously influence.in order to address this problem, the signaling optimization processing method that the present embodiment provides is specially in signalling interactive process shown in Figure 2, storage activates safe mode security configuration information used to UE in this locality, and set up Signaling Radio Bearer and Data Radio Bearer carrying configuration information used, be specially: first, the UE storage this time connects the relevant configuration information (comprise and encrypting and protection algorithm integrallty) of safety that eNodeB sends, namely in as Fig. 2 Security Mode Command message, draw and keep security-related various keys and related algorithm (concrete key and algorithm see 3GPP TS36.331 for details, required for being used for the RRC connection reconstruction, all cells in the signaling that relates in the present invention and 3GPP TS36.331 standard are consistent).Relevant configuration information (for required based on the RRC connection reconstruction of SRB1, specifically seeing 3GPP TS36.331) in the second, UE storage RRC Connection Setup message.The 3rd, UE stores configuration information relevant in RRC Connection Reconfiguration message (be used for keeping based on initiating the RRC connection after the RRC connection reconstruction and reshuffle required configuration information, specifically see 3GPP TS36.331).
