Abstract
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A security problem in which information of a monitoring device is provided to another PLMN exists in the procedure for connecting ProSe Functions of two PLMNs and transmitting and receiving information therebetween, and thus, configuration of a D2D discovery service between different providers (inter PLMN) is difficult in reality, despite being defined in the standard. Therefore, the present invention provides a method of using a content server with an existing D2D discovery method in order to advertise, through D2D discovery, real-time local area advertisements to device of a plurality of providers. A monitoring device requests advertisement information directly from a content server, or requests advertisement information from a different PLMN ProSe Function, and thereby the other PLMN ProSe Function may request advertisement information from a content server.
