协议结构中逻辑信道和传输信道位置 附录:LTE信道映射 附录：SRB0承载的消息 消息名 消息含义 RRC Connection Reestablishment The RRCConnectionReestablishment message is used to resolve contention and to re-establish SRB1. RRC Connection Reestablishment Reject The RRCConnectionReestablishmentReject message is used to indicate the rejection of an RRC connection reestablishment request. RRC Connection Reestablishment Request The RRCConnectionReestablishmentRequest message is used to request the reestablishment of an RRC connection. RRC Connection Reject The RRCConnectionReject message is used to reject the RRC connection establishment. RRC Connection Request The RRCConnectionRequest message is used to request the establishment of an RRC connection. RRC Connection Setup The RRCConnectionSetup message is used to establish SRB1. 附录：SRB1承载的消息（1） 消息名 消息含义 CounterCheck The CounterCheck message is used by the E-UTRAN to indicate the current COUNT MSB values associated to each DRB and to request the UE to compare these to its COUNT MSB values and to report the comparison results to E-UTRAN CounterCheckResponse The CounterCheckResponse message is used by the UE to respond to a CounterCheck message. CSFBParameters RequestCDMA2000 The CSFBParametersRequestCDMA2000 message is used by the UE to obtain the CDMA2000 1xRTT Parameters from the network. The UE needs these parameters to generate the CDMA2000 1xRTT Registration message used to register with the CDMA2000 1xRTT Network which is required to support CSFB to CDMA2000 1xRTT. CSFBParameters ResponseCDMA2000 The CSFBParametersResponseCDMA2000 message is used to provide the CDMA2000 1xRTT Parameters to the UE so the UE can register with the CDMA2000 1xRTT Network to support CSFB to CDMA2000 1xRTT. HandoverFromEUTRA PreparationRequest (CDMA2000) The HandoverFromEUTRAPreparationRequest message is used to trigger the handover preparation procedure with a CDMA2000 RAT. This message is also used to trigger a tunneled preparation procedure with a CDMA2000 1xRT
