Abstract

The invention discloses a terminal reachability management method, a core network and an access network. The method includes: when a terminal supports wireless resources to control an RRC inactive state, sending a request message for requesting terminal reachability information to the access network; receiving the terminal reachability information fed back by the access network according to the request message. When an AMF entity of the core network of the present invention supports the RRC inactive state, if the terminal is in a CM connected state and there are other network element entitiesrequesting the terminal reachability information, the request message for the terminal reachability information is sent to the access network, so that that access network provides feedback of the specific RRC connection state according to the request message, thereby preventing the core network from triggering the access network to send a paging message to an RRC inactive terminal in the process of transmitting services or data and effectively reducing the air interface signaling and unnecessary power consumption of the RRC inactive terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal reachability management method, a core network and an access network. Background technique [0002] Before initiating communication to the terminal, the network device will first detect whether the terminal is reachable, specifically by acquiring terminal reachability management (reachability management) information. Specifically, the network element entities that need to obtain terminal reachability management information include: a network element function (Network Element Function, NEF) entity of a unified data management function (Unified Data Management, UDM) and a short message service center (Short Message Service- Service Center, SMS-SC) entities, etc. Specifically, the network element entity that needs to obtain the terminal reachability management information, through the terminal reachability management request process, requests the Access an...
