1. A method of user discovery, comprising:
- receiving a first message sent by a first terminal device, wherein the first message is used to request to monitor a second terminal device, the first message carries a command word, and the command word is used to apply for monitoring authorization;
sending a second message to the second terminal device, wherein the second message is used to apply to the second terminal device for monitoring authorization, and the second message carries an identity of the first terminal device;
allocating a broadcast code word to the second terminal device;
receiving a third message sent by the second terminal device, wherein the third message is used to indicate whether the second terminal device agrees to be monitored by the first terminal device, and the third message carries an identity of the second terminal device;
if when the third message indicates that the second terminal device agrees to be monitored by the first terminal device, sending a fourth message to the first terminal device, wherein the fourth message carries the identity of the second terminal device and the broadcast code word of the second terminal device; and
receiving an additional message used to initiate a deactivation request, and the additional message carries the broadcast code word of the second terminal device.
