Description

Terminal non-activated state communication sensing method and equipment
Technical Field
The present disclosure relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for sensing a terminal in an inactive state.
Background
In addition to the RRC connected state and the RRC idle state, an RRC inactive state is introduced in the NR system. In the RRC inactive state, the terminal (UE) maintains the context of operation in the last serving cell and allows the terminal to move within a certain range without informing the network which cell it is in. The network side retains the NG interface connection and together with the terminal retains the NAS signaling connection. When the terminal needs to send or receive data, the terminal can start to directly send or receive the data only by adopting an RRC connection recovery process to recover signaling bearers (SRB) and data bearers (DRB), so that the control plane delay of the NR system becomes the delay of the RRC connection recovery process. In addition to the Discontinuous Reception (DRX) cycle broadcasted in the system message, the terminal may also obtain a DRX cycle shorter than this common DRX cycle in order to allow different terminals to behave differently in responding to the page, such as configuring the UE with a shorter DRX cycle than the time delay requirement, so that the terminal pages the corresponding network faster in the RRC inactive state.
In Rel-16, if a terminal that is not in RRC connected state is to perform RAT-related aware positioning, it must first enter RRC connected mode. This may limit the number of terminals that can simultaneously perceive a position fix and increase delay and power consumption. Thus, it is necessary to support the perceived positioning and communication awareness of the terminal in relation to the radio access end (RAT) in the RRC inactive state.
