Abstract

Methods and apparatuses are disclosed for location reporting. A mobility management node determines to establish a connection between the mobility management node and a terminal device for which location reporting is required. The mobility management node sends, to a base station, a request for establishing the connection. The request is configured to request the base station to report location information of the terminal device.

Claims (45)

1. A method implemented at a mobility management node, the method comprising:

determining to establish a connection between the mobility management node and a terminal device for which location reporting is required; and

sending, to a base station, a request for establishing the connection in an INITIAL CONTEXT SETUP REQUEST message, wherein the request is configured to request the base station to report location information of the terminal device by including an information element (IE) for requesting location reporting, in which the IE is a Location Reporting Request Type IE that indicates a type of the requested location reporting, and wherein the type of the requested location reporting is one of:

to report that the terminal device is moving into an area of interest;

to report that the terminal device is moving out of an area of interest; or

to report a location of the terminal device.

2. The method according to claim 1 , wherein the determining to establish the connection comprises any one of:

determining that the terminal device is performing registration update procedure or service request procedure;

determining that the mobility management node is performing service request procedure for the terminal device; or

determining that a network function (NF) has subscribed to mobility event notification from the mobility management node for the terminal device.

3. The method according to claim 2 , wherein the determining that the NF has subscribed to mobility event notification from the mobility management node for the terminal device comprises:

determining the terminal device is to transit from connection management idle (CM-IDLE) state to connection management connected (CM-CONNECTED) state.

4. The method according to claim 1 , wherein the mobility management node is an access and mobility management function (AMF).

5. A method implemented at a base station, the method comprising:

receiving, from a mobility management node, a request for establishing a user equipment context as part of establishment of a connection between the mobility management node and a terminal device in an INITIAL CONTEXT SETUP REQUEST message, wherein the request is configured to request the base station to report location information of the terminal device by including an information element (IE) for requesting location reporting, in which the IE is a Location Reporting Request Type IE that indicates a type of the requested location reporting, and wherein the type of the requested location reporting is one of:

to report that the terminal device is moving into an area of interest;

to report that the terminal device is moving out of an area of interest; or

to report a location of the terminal device; and

reporting, according to the request, the location information of the terminal device to the mobility management node according to the indicated type.

6. The method according to claim 5 , wherein the received request for establishing the connection accompanies any one of:

the terminal device performing registration update procedure or service request procedure;

the mobility management node performing service request procedure for the terminal device; or

a transition of the terminal device from connection management idle (CM-IDLE) state to connection management connected (CM-CONNECTED) state.

7. The method according to claim 5 , wherein the mobility management node is an access and mobility management function (AMF).

8. A mobility management node comprising:

at least one processor; and

at least one memory, the at least one memory containing instructions which, when executed by the at least one processor, cause the mobility management node to:

determine to establish a connection between the mobility management node and a terminal device for which location reporting is required; and

send, to a base station, a request for establishing the connection in an INITIAL CONTEXT SETUP REQUEST message, wherein the request is configured to request the base station to report location information of the terminal device by including an information element (IE) for requesting location reporting, in which the IE is a Location Reporting Request Type IE that indicates a type of the requested location reporting, and wherein the type of the requested location reporting is one of:

to report that the terminal device is moving into an area of interest;

to report that the terminal device is moving out of an area of interest; or

to report a location of the terminal device.

9. The mobility management node according to claim 8 , wherein to determine to establish the connection comprises operations to any one of:

determine that the terminal device is performing registration update procedure or service request procedure;

determine that the mobility management node is performing service request procedure for the terminal device; or

determine that a network function (NF) has subscribed to mobility event notification from the mobility management node for the terminal device.

10. The mobility management node according to claim 8 , wherein the mobility management node is an access and mobility management function (AMF).

11. A base station comprising:

at least one processor; and

at least one memory, the at least one memory containing instructions which, when executed by the at least one processor, cause the base station to:

receive, from a mobility management node, a request for establishing a user equipment context as part of establishment of a connection between the mobility management node and a terminal device in an INITIAL CONTEXT SETUP REQUEST message, wherein the request is configured to request the base station to report location information of the terminal device by including an information element (IE) for requesting location reporting, in which the IE is a Location Reporting Request Type IE that indicates a type of the requested location reporting, and wherein the type of the requested location reporting is one of:

to report that the terminal device is moving into an area of interest;

to report that the terminal device is moving out of an area of interest; or

to report a location of the terminal device; and

reporting, according to the request, the location information of the terminal device to the mobility management node according to the indicated type.
