送Msg1，发起基于竞争的RA。gNodeB向UE发送Msg2，发送RA响应。UE向gNodeB发送RRCSetupRequest
消息（在初始的RA中，Msg3传输的是RRCSetupRequest消息），RRCSetupRequest消息携带RRC建立原因和
UE标识，请求建立RRC连接。其中；RRC连接建立原因由上层设定。UE标识可以是S-TMSI或随机数。如果上层提供了S-TMSI，
则携带S-TMSI信息给gNodeB。如果没有S-TMSI信息，则生成一个0~239-1之间的随机数给gNodeB。gNodeB为
UE建立上下文。当gNodeB在gNBConnStateTimer.http://localhost:7890/pages/GZJ

L/ratN/para/gNBConnStateTimer-UuMessageWaitingTimer.htmlUuMessage
WaitingTimer时间窗内，收到同一个UE的多次RRCSetupRequest消息，则gNodeB只处理近一次的RRC连接建
立请求。gNodeB进行SRB1资源的准入和资源分配。如果SRB1资源准入或者资源分配失败，则gNodeB向UE回复RRCReje
ct消息，本次RRC建立过程失败。否则，执行http://www.tenglingkj.cn/16766/16784.html6和
http://www.tenglingkj.cn/16766/16784.html7。gNodeB向UE回复RRCSetup消息，
消息中携带SRB1资源配置的详细信息。UE根据RRCSetup消息指示的SRB1资源信息，进行无线资源配置，然后发送RRCSetu
pComplete消息给gNodeB，RRC连接建立完成。gNodeB发送RRCSetup消息后，启动等待RRCSetupComp
lete消息的定时器（时长通过gNBConnStateTimer.http://localhost:7890/pages/GZJ0

nnectionSetupComplete：RRC连接建立完成?二、上下文建立流程?RRC建立成功后，UE向gNodeB发送RRC
SetupComplete消息。RRCSetupComplete消息中携带selectedPLMN-Identity、regist
eredAMF、s-nssai-list和NAS。gNodeB为UE分配专用的RAN-UE-NGAP-ID，gNodeB根据sel
ectedPLMN-Identity、registeredAMF、s-nssai-list选择AMF节点，然后将RRCSetupC
omplete消息中携带的NAS通过InitialUeMessage发送给AMF，触发NG-C连接建立gNodeB透传UE和AMF
之间的NAS直传消息，完成IDENTITY查询、鉴权、NAS安全模式和注册过程等。AMF向gNodeB发送INITIALCONT
EXTSETUPREQUEST消息，启动初始上下文建立过程。仅当INITIALCONTEXTSETUPREQUEST消息
中未携带UERadioCapabilityIE时，在安全模式过程完成后，gNodeB才会向UE发送UECapabilityE
nquiry消息，发起UE能力查询过程，对应7~9。否则，后续流程跳过7~9。仅当INITIALCONTEXTSETUPRE
QUEST消息中携带了PDUSessionResourceSetupRequestListIE时，在UE能力查询过程完
成后，gNodeB才会向UE下发经过加密与完整性保护的RRCReconfiguration消息，指示UE建立SRB2和DRB，对应10和11。否则，后续流程跳过10和11。gNodeB向UE发送SecurityModeCommand消息，通知UE启动完整性保护和加密过程。此后，启动下行加密。UE根据SecurityModeCommand消息指示的完整性保护和加密算法，派生出密钥，然后向gNodeB回复SecurityModeComplete消息。此后，启动上行加密。gNodeB向UE发送UECapabilityEnquiry消息，发起UE能力查询过程。UE向gNodeB回复UECapabilityInformation消息，携带UE能力信息。gNodeB向AMF发送UERADIOCAPABILITYINFOINDICATION消息，透传UE能力。gNodeB向UE下发RRCReconfiguration消息，指示建立SRB2和DRB。在专用NG-C连接建立过程中的加密与完整性保护执行完之后，gNodeB向UE发送携带srb-ToAddModList信元的RRCReconfiguration消息，指示UE建立SRB2和DRB。UE收到RRCReconfiguration消息后，开始建立SRB2和DRB。UE根据消息指示：建立对应的PDCP实体并配置相关安全参数。建立并配置RLC实体。建立并配置DCCH逻辑信道。SRB2和DRB建立成功后，UE向gNodeB回复RRCReconfigurationComplete消息。gNodeB向AMF回复INITIALCONTEXTSETUPRESPONSE消息。NAS鉴权、安全模式信令????RRC安全模式命令&RRC安全模式完成??UECapabilityEnquiry&UECapabilityInformation??RRCReconfiguration&RRCReconfigurationComplete说明此处的RRC连接重配虽无INITIALCONTEXTSETUPREQUEST信令分析，但根据以上流程分析应未携带PDUSessionResourceSetupRequestList，故跳过了10和11步骤，SRB2和DRB需要再PDU会话建立完成后建立。本条RRC连接重配为测量配置。? |
