Abstract

A trigger discovery method includes: sending a wake-up discovery request to a network device, where the wake-up discovery request is used for requesting the network device to trigger a second terminal to start a discovery process, and there is a subscription binding relationship between the second terminal and the first terminal; and starting the discovery process in a case that a response message sent by the network device is received, where the response message is used for indicating that the second terminal has started the discovery process.

3. The method according to claim 1 , wherein the response message carries at least one of a discovery mode corresponding to the discovery process, discovery start time, a discovery duration, or dedicated verification and authentication information; and

the starting the discovery process comprises:

starting the discovery process according to the discovery mode in a case that the response message carries the discovery mode;

starting the discovery process according to the discovery start time in a case that the response message carries the discovery start time;

starting, in a case that the response message carries the discovery duration, the discovery process, and sustaining the discovery process according to the discovery duration; and

starting, in a case that the response message carries the dedicated verification and authentication information, the discovery process, and performing verification and authentication on the second terminal in the discovery process based on the dedicated verification and authentication information.

4. The method according to claim 1 , wherein before the sending the wake-up discovery request to the network device, the method further comprises:

receiving the subscription binding configuration information configured and sent by the network device.

5. A trigger discovery method, performed by a second terminal and comprising:

starting a discovery process based on the discovery start command;

wherein subscription binding configuration information is pre-configured in the second terminal or a universal subscriber identity module (USIM) card of the second terminal; and the subscription binding configuration information comprises identification information of the first terminal, identification information of the second terminal, and binding group identification information corresponding to the subscription binding relationship; and

the subscription binding configuration information further comprises at least one of the following: capability information of the first terminal, capability information of the second terminal, the dedicated verification and authentication information, or default configuration information.

6. The method according to claim 5 , wherein the wake-up discovery request carries at least one of identification information of the first terminal, identification information of the second terminal, binding group identification information corresponding to the subscription binding relationship, a discovery mode corresponding to the discovery process, discovery start time, a discovery duration, or dedicated verification and authentication information.

7. The method according to claim 5 , wherein the discovery start command carries at least one of a discovery mode corresponding to the discovery process, discovery start time, a discovery duration, or dedicated verification and authentication information; and

the starting a discovery process comprises:

starting the discovery process according to the discovery mode in a case that the discovery start command carries the discovery mode;

starting the discovery process according to the discovery start time in a case that the discovery start command carries the discovery start time;

starting, in a case that the discovery start command carries the discovery duration, the discovery process, and sustaining the discovery process according to the discovery duration; and

starting, in a case that the discovery start command carries the dedicated verification and authentication information, the discovery process, and performing verification and authentication on the first terminal in the discovery process based on the dedicated verification and authentication information;

wherein before the starting a discovery process, the method further comprises:

determining a pre-configured default discovery mode as the discovery mode in a case that the discovery start command does not carry the discovery mode.

8. The method according to claim 5 , wherein after the starting a discovery process, the method further comprises:

sending a discovery start confirm message to the network device, wherein the discovery start confirm message is used for indicating that the second terminal has started the discovery process, and the discovery start confirm message carries at least one of a discovery mode corresponding to the discovery process, discovery start time, a discovery duration, or dedicated verification and authentication information.

9. The method according to claim 5 , wherein before the receiving the discovery start command sent by the network device, the method further comprises:

receiving the subscription binding configuration information configured and sent by the network device.

10. A trigger discovery method, performed by a network device and comprising:

receiving a wake-up discovery request sent by a first terminal, wherein the wake-up discovery request is used for requesting the network device to trigger a second terminal to start a discovery process, and there is a subscription binding relationship between the second terminal and the first terminal;

sending a discovery start command to the second terminal based on the wake-up discovery request; and

sending a response message to the first terminal after the second terminal starts the discovery process based on the discovery start command, wherein the response message is used for indicating that the second terminal has started the discovery process.

11. The method according to claim 10 , wherein the wake-up discovery request carries at least one of identification information of the first terminal, identification information of the second terminal, binding group identification information corresponding to the subscription binding relationship, a discovery mode corresponding to the discovery process, discovery start time, a discovery duration, or dedicated verification and authentication information.

12. The method according to claim 11 , wherein the sending the discovery start command to the second terminal comprises:
