Abstract

A positioning method, a relay device, an Internet of Things device, a terminal, and a network device are provided. The positioning method includes: determining a to-be-positioned device in a case that Internet of Things devices are associated, or positioning the to-be-positioned device. The to-be-positioned device includes a first Internet of Things device, and the first Internet of Things device is at least one of the Internet of Things devices associated with a relay device.

First claim

What is claimed is:

1 . A positioning method, performed by a relay device, comprising:
sending a capability interaction message to a first device, wherein the first device comprises: a first Internet of Things device that is associated with the relay device, or a network device, wherein when the first device is the network device, the capability interaction message sent to the network device comprises capability information of the relay device, wherein the capability information of the relay device comprises at least one of the following:
whether the relay device supports establishing an association with the first Internet of Things device,
whether the relay device supports positioning the first Internet of Things device,
whether the relay device supports reporting location information of the first Internet of Things device,
whether the relay device supports transmitting a positioning assistance message corresponding to the first Internet of Things device,
whether the relay device supports capability interaction with the first Internet of Things device,
whether the relay device supports being positioned by Internet of Things devices, or
whether the relay device supports measuring a reference signal sent by the Internet of Things devices;
determining a to-be-positioned device when the Internet of Things devices are associated, or positioning the to-be-positioned device, wherein the to-be-positioned device comprises the first Internet of Things device, and the first Internet of Things device is at least one of the Internet of Things devices associated with the relay device; and receiving location request information corresponding to the to-be-positioned device, or sending the location request information corresponding to the to-be-positioned device, wherein the location request information is used for determining the to-be-positioned device or positioning the to-be-positioned device position, and the location request information comprises at least one of the following: a type of the to-be-positioned device, a location request type of the to-be-positioned device, or identification information of the to-be-positioned device.

2 . The positioning method according to claim 1 , wherein the determining a to-be-positioned device, or positioning the to-be-positioned device comprises at least one of the following:
determining the to-be-positioned device or positioning the to-be-positioned device according to a service request; determining the to-be-positioned device or positioning the to-be-positioned device according to a positioning assistance message; or determining the to-be-positioned device or positioning the to-be-positioned device according to the location request information.

3 . The positioning method according to claim 2 , further comprising at least one of the following:
sending a first request to a network device, wherein the first request is used for obtaining the positioning assistance message; or receiving the positioning assistance message sent by the network device, wherein the positioning assistance message is used for determining the to-be-positioned device or positioning the to-be-positioned device.

4 . The positioning method according to claim 2 , wherein the positioning assistance message comprises at least one of the following:
identification information of the to-be-positioned device; or first information for positioning the to-be-positioned device.

5 . The positioning method according to claim 4 , wherein the first information comprises at least one of the following:
information of a reference signal measured by the first Internet of Things device; information of a reference signal sent by the first Internet of Things device; information required by the first Internet of Things device to perform Global Navigation Satellite System (GNSS) related positioning; information required by the first Internet of Things device to perform sensor positioning; a positioning method in which the relay device positions the first Internet of Things device; information of a reference signal sent by the relay device to the first Internet of Things device; information of a reference signal received by the relay device from the first Internet of Things device; information requested by the relay device from the first Internet of Things device; or location information and time information of the network device.

6 . The positioning method according to claim 2 , wherein the positioning assistance message comprises first indication information, and the first indication information is used for indicating at least one of the following:
whether to send the positioning assistance message to the to-be-positioned device; or an association relationship between the positioning assistance message and the to-be-positioned device.

7 . The positioning method according to claim 1 , wherein the positioning the to-be-positioned device comprises:
receiving location information sent by the to-be-positioned device.

8 . The positioning method according to claim 7 , wherein the location information comprises at least one of the following:
location measurement information or location information of the to-be-positioned device; or relative location information of the to-be-positioned device.

9 . The positioning method according to claim 1 , further comprising at least one of the following:
reporting location information obtained by positioning the to-be-positioned device; or reporting identification information of the to-be-positioned device.

10 . The positioning method according to claim 1 , further comprising:
receiving the capability interaction message from the first device.

11 . The positioning method according to claim 10 , wherein the capability interaction message sent to the network device further comprises at least one of the following:
identification information of the relay device; identification information of the first Internet of Things device; or capability information of the first Internet of Things device.

12 . The positioning method according to claim 11 , wherein the capability information of the first Internet of Things device comprises at least one of the following:
whether the first Internet of Things device supports capability interaction with the relay device; whether the first Internet of Things device supports positioning assistance message and location information interaction with the relay device; a positioning method supported by the first Internet of Things device; a positioning manner supported by the first Internet of Things device; a reporting manner supported by the first Internet of Things device; a measurement capability supported by the Internet of Things device; a reporting capability supported by the Internet of Things device; a power control capability supported by the Internet of Things device; a space relativity capability supported by the Internet of Things device; or a signal processing capability supported by the Internet of Things device.

13 . The positioning method according to claim 10 , wherein the capability interaction message received from the first Internet of Things device or sent to the first Internet of Things device comprises at least one of the following:
identification information of the first Internet of Things device; or capability information of the first Internet of Things device.

14 . The positioning method according to claim 1 , wherein the first Internet of Things device is in one of the following states: a connected state, an idle state, or an inactive state.
