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.

摘要： An apparatus and method for dynamically allocating a multicast path in a broadband wireless access system are provided. A method for an operation of a server providing a multicast service through a wireless access network includes determining to establish multicast paths for a first Base Station (BS) and at least one neighboring BS of the first BS when a terminal receiving the multicast service enters a network through the first BS, and transmitting a control station a message of instructing to establish the multicast path for a BS not holding the multicast path among the first BS and the at least one neighboring BS of the first BS.

摘要： Expected channel occupancy time is a wireless link metric determined based on a transmission protocol to be used for transmitting data in a wireless network. The wireless link metric may be used for routing or other network management functions. For determining the wireless link metric, an overhead is determined for one or more of accessing and releasing a channel to transmit a burst, including at least one frame, in the wireless network using the transmission protocol. An expected burst transmission time is calculated based at least on the overhead. The expected channel occupancy time is determined from the expected burst transmission time and an estimation of a number of frames to be successfully delivered during the burst.
