Evolutionary node B, user device and method for transition between idle mode and connection mode

摘要

Problem to be solved: to provide an evolutionary node B (ENB) and a communication method for a transition between an idle mode and a connection mode.In the communication method, ENB receives an uplink data packet from the UE using a lightweight wireless resource control (RRC) between ENB and UE.The ENB sends an RRC connection release message to the UE to notify the transition of the UE to the RRC idle mode of the RRC connection, and 525, the RRC connection release message includes an indicator of whether the UE stores context information for the RRC connection.The ENB also receives a further uplink data packet according to context information stored using the lightweight RRC connection 550.Diagram
