    摘要： An apparatus and a method for setting a group communication session using a wireless access system are provided. The method includes transmitting, at a transmission side client, a message requesting start/end of group communication to a control Push To Talk (PTT) server, transmitting, at the control PTT server, a session set/end message including a sequence number to a participating PTT server, multicasting, at the participating PTT server, a connect/disconnect request message N times for at least one reception side client, and setting/releasing, at the at least one reception side client, a session for the group communication.

    摘要： An apparatus and a method for managing an access state of a terminal for a group communication service in a wireless communication system are provided. In a method for operating a terminal for a group communication service in a wireless communication system, a bandwidth ranging message is transmitted to a base station in an idle state. The terminal is allocated an uplink resource from the base station. A message for access state transfer including a multicast Connection IDentifier (CID) is generated. The message for access state transfer is transmitted to the base station via the allocated uplink resource.
