The Radio Resource Control (RRC) establishment request message is a request message for RRC establishment, which is sent by a terminal to a base station. The RRC establishment request message includes a first packet header and a first packet body, where first packet header information carried by the first packet header may include a Cell identification code CellID and a Cell-radio network temporary identifier (C-RNTI), and first packet body information carried by the first packet body may include information such as a terminal Identity identifier UE-Identity and context information of a terminal (User Equipment, UE) in the RRC request-IEs. A hash node may be established with the first packet header information as a key and the first packet body information as a value.
And step 120, associating the RRC establishment request message with the RRC message according to the first key information of the first key value pair node and the second header information or the second packet information of the RRC message.
Wherein, the RRC message is other radio resource control messages except for the RRC establishment request message, which are transmitted between the terminal and the base station. The RRC message comprises a second header or a second header and a second packet body, the second header or the second packet body information of the RRC message is compared with the first key information, if the second header or the second packet body information of the RRC message is consistent with the first key information, the RRC establishment request message is associated with the RRC message, the first key information of the node can be acquired by inquiring the RRC message, and the RRC message can be used in the subsequent association with other interfaces of the 5G or network optimization and the like.
It should be noted that the terminal is various devices with communication functions, including a handheld device, an in-vehicle device, a wearable device, a computing device, and the like. The base station is a base station device, and is a device deployed in a radio access network to provide a wireless communication function. The apparatus providing base station functionality, for example in 5G, includes a node B that continues to evolve (gNB). The terminal has three states, namely an RRC IDLE state RRC _ IDLE, an RRC INACTIVE state RRC _ INACTIVE and an RRC CONNECTED state RRC _ CONNECTED. When the terminal state is changed from RRC _ IDLE to RRC _ CONNECTED, the RRC is triggered to establish a Setup flow; when the terminal state is changed from RRC _ INACTIVE to RRC _ CONNECTED, an RRC repairing Resume flow is triggered; when the terminal state is changed from RRC _ CONNECTED to RRC _ INACTIVE or from RRC _ CONNECTED to RRC _ IDLE, the RRC Release flow is triggered; in the RRC _ CONNECTED procedure, RRC Reconfiguration or RRC reestablishment of the reestablishment procedure is triggered.
