Title: METHOD, DEVICE AND SYSTEM FOR BROADCASTING AND MONITORING DEVICE-TO-DEVICE LIMITING DISCOVERY SERVICE
Abstract:
The present invention provides a method, device and system for broadcasting and monitoring a device-to-device (D2D) limiting discovery service. The broadcasting method comprises: a broadcasting terminal (A-UE) sends a service request message to a distance-based service (ProSe) server (S402); the A-UE receives a discovery service code that is acquired after the ProSe server successfully authenticates the service request message (S404); and the A-UE broadcasts the discovery service code (S406). The present invention solves the problem in the prior art of a complex process of implementing a D2D discovery service due to the fact that a limiting discovery service must require service permission of a ProSe server, so that an A-UE can directly acquire broadcast or authentication permission from the ProSe server instead of using a ProSe functional entity, thereby simplifying the process steps of the discovery service.
