Abstract: A method of providing power management in a Wireless Local Area Network (WLAN) is presented. The method includes receiving a Traffic Indication Map (TIM) at a station, indicating the presence of buffered frames, associated with any AC, for the station at an Access Point (AP). The method further includes sending, by the station, one of an uplink data frame if one is buffered, and a null frame to retrieve the buffered frames from said AP. The station remains awake to receive frames from the AP until a downlink frame is received containing an indication that it is the last frame to be transmitted in the service period. The method may further include determining at the end of service period whether there are more frames remaining buffered for the station at the AP.

Abstract: A method, apparatus and computer program product for preventing occurrences of the hidden node problem are presented. A transmission request (CC-RTS) is received from a source node, the CC-RTS frame including a reservation duration value indicating the length of time needed for a transmission reservation. A timer is adjusted for the period other nodes must refrain from transmitting on the channel (NAV) equal to a duration of a transmission request/transmission response (CC-RTS/CC-CTS) handshake. When the CC-RTS has been denied, then a second CC-RTS frame is received having a reservation duration value of zero, and when the CC-RTS is accepted then the NAV is extended to remainder of the reservation duration value of the original CC-RTS frame. The CC-RTS and CC-CTS are sent at a more robust PHY mode than traffic frames.

Abstract: A method, apparatus and computer program product for avoiding exposed nodes in Wireless local Area Networks is presented. The method includes maintaining at a node a first timer (NAV_RTS) for a channel which, if set, prevents the node from authorizing a transmission on the channel to itself and maintaining at the node a second timer (NAV_CTS) for the channel which, if set, prevents the node from transmitting on the channel. The method further includes updating the NAV_RTS when a transmission request (CC-RTS) frame is received having a reservation duration value greater than zero and greater than a current value of the NAV_RTS, and updating the NAV_CTS when a transmission response (CC-CTS) frame is received having a reservation duration value greater than zero and greater than a current value of the NAV_CTS.

Abstract: A method and apparatus for maintaining a connection between a wireless transmit/receive unit (WTRU) and a blanket wireless local area network (BWLAN) are described. An inter-working function (IWF) entity in a given network access point (NAP) of the BWLAN maintains lists of WTRUs in respective states. Furthermore, the given NAP maintains a list of neighbor NAPs, and operates in accordance with a selected WTRU mobility protocol. The states may include a "not aware" (NA) state in which the given NAP is actually not aware of a particular WTRU, an "active transmit" (AT) state in which the given NAP is actively transmitting to a particular WTRU, and a "neighbor range" (NR) state for WTRUs indicated in an update report from neighbor (URN) message that the given NAP was not aware of. The WTRU mobility protocol may be a push mobility protocol or a poll mobility protocol.

Abstract: As is reflected in the disclosed method and apparatus, the present invention is a technique to account for the variation in channel occupancy of a particular terminal or terminals during the call admission process. Instead, a channel utilization manager accounts for the probabilistic nature of the call admission decision by using a pre determined, statistically justified value to represent the channel occupancy. The “per- call” channel occupancy value is determined by a number of factors, including the shared-communications channel data rate. Channel occupancy is incorporated into one or more cumulative distribution functions (CDF), which are evaluated by the channel utilization manager as part of the call admission process. In turn, each channel- occupancy CDF of a shared-communications channel can be generated from a CDF of the terminals' data rates on that channel, which data rates can be determined analytically or empirically.

Abstract: The present invention provides a technique for directly calling telephones (111-113) via a shared telephone, which telephones do not have telephone numbers in the address space of the Public Switched Telephone Network (PSTN). This is particularly useful for visitors and guests who are (111-113), for example, temporarily at a hotel, school campus, or number business.

Abstract: A technique is disclosed that enables a voice call to be initiated on the Public Switched Telephone Network and directed to a VoIP telephone on the Internet without the association of a unique telephone number to the VoIP telephone. In accordance with the illustrative embodiment of the present invention, a user who has a PSTN wireline telephone or a PSTN cell phone associates his or her VoIP telephone with the telephone number of the PSTN wireline telephone or the PSTN cell phone or with both numbers. In other words, the VoIP telephone is not assigned its own telephone number but shares the telephone number of the PSTN telephones of its owner.
