Abstract
Provided is a device-to-device (D2D) group communication control method. In the D2D group communication control method, D2D group session information is generated and transmitted when a D2D group service request or a D2D group communication sensing report is received. When a D2D group session confirmation message is received according to the D2D group service request or the D2D group communication sensing report, D2D group session setup is determined to be successful. A D2D group service response message or a D2D group service start message is transmitted to at least one device belonging to a D2D group for which the D2D group session setup is completed. Thereby, centralized D2D group session management can be performed. Accordingly, the number of connections of separate direct communication can be reduced and hence a signaling load can be reduced.
