Abstract: PURPOSE: A direct communication conducting method between terminals is provided to simultaneously support cellular communication and direct communication between terminals by mutually allocating basic direct communication resources regardless of a base station. CONSTITUTION: A first terminal and a second terminal share information for basically assigned direct communication resources(S900). The first terminal transmits data to the second terminal by using the basically assigned direct communication resources as the use of direct communication(S910). The first terminal receives the data from the second terminal by using the basic direct communication resource(S920). Control information is unnecessary to be transmitted for the direct communication resources by using resources for cellular communication. Influence on a legacy terminal which does not support inter-terminal direct communication is minimized.

Abstract: PURPOSE: A conversion method between multicast connection and unicast connection is provided to change the multicast connection into the unicast connection in a group communication according to situations. CONSTITUTION: A base station establishes multicast connection in plural mobile stations which attend to group communication. The base station changes unicast connection which respectively connects each mobile station into the multicast connection. The base station releases the unicast connection between mobile stations. In case the number of the mobile stations or the channel state of the mobile station is higher than threshold values, the base station changes the unicast connection into the multicast connection.
