在5G(NR)网络中RRC连接重建(RRC connection re-establishment)的目的是恢复此前已建立的RRC连接。此时终端(UE)已处于RRC_CONNECTED状态(其安全性已通过,建有SRB2),空口至少有一个业务承载(DRB)被激活(在IAB中已建立的SRB2被激活)以恢复原有的无线资源连接。 在R16版本中定义了三种RRC重建原因,它们分别是:reconfig...

METHOD FOR OPTIMAL RESOURCE ALLOCATION DURING RRC CONNECTION ESTABLISHMENT IN 5GThe disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for optimizing resource allocation to allocate one or more resources of a base ...
5g rrc连接重建信令流程 The 5G RRC (Radio Resource Control) connection re-establishment signaling process is a crucial aspect of wireless communication networks. It involves a series of procedures designed to restore a disrupted connection between a mobile device and the network, ensuring seamless ...
1)UE收到RRCConnectionSetup或RRCConnectionReject; 2)触发Cell-reselection过程; 3)NAS层终止RRC connection establishment过程。 如果定时器超时, 则 UE 触发以下操作。 1)重置MAC层 2)释放MAC层配置 3)重置所有已建立RBs(Radio Bears)的RLC实体,通知高层 RRC connection establishment失败。
NR 5G RRC连接重建 RRC连接重建流程图RRC连接重建过程描述 1、UE向gNB-DU发送前导码。 2、gNB-DU分配新的C-RNTI并用RAR响应UE。3、UE向包含旧C-RNTI和旧PCI的gNB-DU发送RRCCONNECTION REESTABLISHMENT REQUEST消息。 4、gNB-DU包括RRC消息,并且如果UE被允许,则在F1-AP初始ULRRC消息传送消息中包括用于UE的相应...

When UE is power up it is in Disconnected mode/Idle mode, It can move RRC connected with initial attach or with connection establishment. If there is no activity from UE for a short time, It can suspend its session by moving to RRC Inactive and can resume its session moving to RRC conn...
