Abstract

Disclosed is a discovery method and apparatus for device-to-device (D2D) communication in a cellular mobile communication system. The discovery method performed by the discovery apparatus may include obtaining, from a server managing information associated with terminals providing a service using a D2D communication scheme over a mobile communication network, information associated with a service provided by the terminals, selecting a service of interest based on the information associated with the service, receiving, from a base station, information associated with a discovery radio resource allocated to the terminals providing the service of interest, and discovering the terminals providing the service of interest based on the information associated with the discovery radio resource.

Claims15

Dependent claims

A discovery method performed by a discovery apparatus, the discovery method comprising:

transmitting, to a server, a service information request message requesting information associated with a service provided by one or more terminals;
obtaining, from the server, managing information associated with the one or more terminals providing the service using a device-to-device (D2D) communication scheme over a mobile communication network, wherein information associated with the service is provided by the one or more terminals;
selecting a service of interest based on the information associated with the service;
receiving, from a base station, information associated with a discovery radio resource allocated to a terminal providing the service of interest;
and
discovering the terminal providing the service of interest based on the information associated with the discovery radio resource;
wherein the service information request message includes information associated with an identification (ID) of the base station and a category of the service of interest.

A discovery apparatus comprising:

an obtaining unit to obtain, from a server managing information associated with one or more terminals providing a service using a device-to-device (D2D) communication scheme over a mobile communication network, information associated with a service provided by the terminals;
a selection unit to select a service of interest based on the information associated with the service;
a discovery unit to discover a terminal providing the service of interest based on information associated with a discovery radio resource allocated to the terminal providing the service of interest received from a base station;
and
a transmission unit to transmit, to the server, a service information request message requesting information associated with the service provided by the terminals;
wherein the service information request message includes information associated with an identification (ID) of the base station and a category of the service of interest, and the information associated with the service corresponds to information associated with a service corresponding to the category of the service of interest among services provided through the base station corresponding to the ID of the base station.
