Wireless connection state management system and method for user terminal inactive state

Abstract

This application discloses a wireless connection state management system and method of non -activated status of a user terminal.The system includes: the first network device, which is deployed on the side of the access network; the path switching request meter function, the road switching request meter function is deployed on the core network side; the wireless access network basic notification areaUpdate the timing function, and the wireless access network basic notification area updates the timing function deployment on the core network side; access and mobile management functions AMF, which is deployed on the core network side by the access and mobile management functions AMF.The system and method of this application, for the user terminals in non -activated state, timed and calculated the state of the request according to its path switching to the time of the request to judge the time when the user terminal is in a non -activated state, and then the user terminal conversion of the user terminal that has been in a non -activated state for a long time is conversion for a long time.For the idle state, the energy consumption of signaling expenses and user terminals is saved.

Description

technical field [0001] The present application relates to the field of mobile communication technologies, and in particular, to a wireless connection state management system and method in an inactive state of a user terminal. Background technique [0002] In 5G NR, RRC (Radio Resource Control, Radio Resource Control) is the message configuration center and control center of the access layer of the entire wireless communication protocol stack. The RRC layer supports sending the dedicated NAS signaling generated by the UE or core network elements to the opposite end over the air interface, and also sends the public NAS layer messages to the user terminal (UE) through system broadcast. In addition, the main functions of RRC also include monitoring and paging, RRC connection control, security functions, establishment, maintenance and release of SRB and DRB. [0003] In the 3GPP standard, the radio connection state of the RRC layer is divided into three states: RRC_IDLE, RRC_CON...

AI Technical Summary

Problems solved by technology

[0004] In the 5G network, due to the dense deployment of small base stations and smaller cell coverage, the UE needs to perform frequent location updates when moving between cells and the paging difficulty of users increases, which brings a lot of location updates and paging to the network. signaling overhead

[0005] However, for a UE in the RRC_INACTIVE state for a long time, multiple RNAU processes will occupy a large amount of air interface signaling overhead, and multiple interactions will also increase the energy consumption of the terminal. Especially in 5G networks, due to the dense deployment of small base stations, UE During the process, the RNAU process may be frequently required, resulting in long-term occupation and consumption of resources
