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 mess
