US 11,310,658 B2 · Method and apparatus for determining status of terminal device, and device

Abstract

A method and an apparatus for determining a status of a terminal device, and a device are disclosed. The method includes: obtaining, by an access and mobility management network element, an access type used by the terminal device to access a network, where the access type includes at least one of 3rd generation partnership project (3GPP) access and non-3GPP access; and determining, by the access and mobility management network element based on a status of the terminal device in the access type, the status of the terminal device, where the status of the terminal device includes at least one of a loss-of-connectivity state and an available-to-connectivity state. By using the method according to the embodiments of the present disclosure, accuracy of determining the status of the terminal device is improved.

Dependent claims

A method for determining a status of a terminal device, comprising:

obtaining, by an access and mobility management network element, an access type used by the terminal device to access a network, wherein the access type comprises at least one of 3rd generation partnership project (3GPP) access and non-3GPP access;
determining, by the access and mobility management network element, a connection management status of the terminal device, which indicates whether the terminal device is in a connected state or an idle state;
determining, by the access and mobility management network element, a mode of the terminal device, wherein the mode of the terminal device is one of a plurality of modes, including a mobile initiated connection only (MICO) mode;
and
determining, by the access and mobility management network element, the status of the terminal device based on the access type used by the terminal device, the connection management status, and the mode of the terminal device, wherein the status of the terminal device is a loss-of-connectivity state or an available-to-connectivity state.

2 more elements

A method of determining a status of a terminal device, comprising:

obtaining, by an access and mobility management network element, first information of the terminal device, wherein the first information comprises location information of the terminal device, and a protocol data unit (PDU) session state of the terminal device in a local area data network (LADN), wherein the location information of the terminal device indicates whether the terminal device is located within a restricted service area;
and
determining, by the access and mobility management network element, the status of the terminal device based on the first information, wherein the status comprises at least one of a loss-of-connectivity state and an available-to-connectivity state.
