Abstract

The invention discloses a paging method, which comprises the following steps that: user equipment receives a paging message from a target base station in a standby state, and the paging message comprises a core network identifier of the user equipment; the user equipment judges whether the target base station belongs to a notification area where the user equipment resides; if the target base station belongs to the notification area, the user equipment recovers the connection with the target base station in the standby state to change from the standby state to the connection state, and if the target base station does not belong to the notification area, the user equipment enters an idle state and then establishes connection with the target base station to change from the idle state to the connection state. The invention also discloses a paging device. In this way, the signaling overhead and the processing overhead can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a paging method and device. Background technique [0002] In the new radio (New Radio, NR), the user equipment (User Equipment, UE) has three states, radio resource control (Radio Resource Control, RRC) connected (RRC_CONNECTED) state, RRC inactive (RRC_INACTIVE) state and RRC idle ( RRC_IDLE) state. [0003] A UE in the RRC_INACTIVE state still has a core network (Core Network, CN)-radio access network (Radio Access Network, RAN) connection relationship, and a base station that maintains the CN-RAN connection relationship of the UE and stores the UE context (context) is called The anchor base station is responsible for configuring the notification area for the UE. At the same time, the core network regards the UE in the RRC_INACTIVE state as an Evolved Packet System (EPS) connection management (EPSConnection Management, ECM) connection state, which means that the core network conside...
