| 摘要 | A device discovery method includes: enabling, by a first device, a device-to-device monitoring and broadcasting function; after the first device detects broadcast information of a second device, reporting the broadcast information of the second device and a user identifier of a target user to a network side, requesting that the network side obtains, according to the broadcast information of the second device, an identifier of a user that logs in to the second device, and determines whether the identifier of the user that logs in to the second device is the user identifier of the target user; and receiving a result of the determining returned by the network side, and confirming, by the first device according to the result of the determining, whether a device to which the target user logs in falls within a preset distance from the first device. | ||

| 主权项 | 1. A device discovery method, wherein the method comprises: enabling, by a first device, a device-to-device (D2D) monitoring and broadcasting function; detecting, by the first device, broadcast information of a second device; after the detecting, reporting the broadcast information of the second device and a user identifier of a target user to a network side, wherein the target user is a user that has to log-in to the second device so that the first device performs D2D communication with the second device only when the second device is located within a preset distance from the first device; requesting the network side to obtain, according to the broadcast information of the second device, an identifier of a user that logs-in to the second device, and to determine whether the identifier of the user that logs-in to the second device is the user identifier of the target user; receiving, by the first device, a result of the determining returned by the network side; confirming, by the first device according to the result of the determining, whether a device to which the target user logs-in is the second device; and performing, by the first device, the D2D communication with the confirmed second device to which the target user logged-in. | ||
