Proximity map request method, server and network entity using the same, proximity request validating method, and server and network entity using the same

摘要

The present disclosure proposes a proximity map request method, a server and a network entity using the same, a proximity request validating method, and a server and a network entity using the same. In one of the exemplary embodiments, the server receives a proximity map request message of a D2D discovery to request a network level user ID of the discoveree. The proximity map request message may include an application layer user ID of the discoverer and an application layer user ID of the discoveree. The server may set a notification flag according to the application layer user ID of the discoverer and the application layer user ID of the discoveree in response to receiving the proximity map request message. The server may transmit a proximity map response message comprising the network level user ID of the discoveree and the notification flag in response to setting the notification flag.
