摘要： A method and system is disclosed for setting up, modifying and tearing down an up-stream communication session in a basic service set (BSS) in a wireless local area network (WLAN), so that the communication session has a defined Quality of Service (QoS). Regarding setting up an up-stream communication session, a first Path message and a first Resv message (Path/Resv message) of a RSVP protocol are detected at a designated subnet bandwidth manager (DSBM) in a station having a point coordinator (PC). The first Resv message originates from a RSVP agent of a host outside the BSS, and is a request for setting up an up-stream session between a source non-PC station in the BSS and the PC station. A QoS parameter set and a classifier from the first Path/Resv message for the session are extracted at the DSBM. The DSBM determines whether to admit the up-sam session to the network based on the QoS parameter set defining the session and a channel status report on a medium access control (MAC) sublayer of the BSS. When the up-stream session is admitted, a QoS management entity (QME) of the PC station sets up a virtual up-stream (VUS) between the source non-PC station and the PC station for transporting the up-stream session traffic. The DSBM is part of the QME in the PC station.

摘要： A new protocol system and method is described that utilizes a Schedule Information Vector (SIV) protocol for saving power in wireless local area networks. The protocol includes an access point, one or more stations, and an SIV frame including an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. The access point originates and transmits the SIV frame protocol of the scheduled wake-up time to the stations. The SIV frame protocol of the wireless network is further operable to dynamically adjust the scheduled wake-up times of the stations, a sequence of the wake-up times, a periodic wake-up time, a plurality of wake-up times, and a duration of the wake-up times of the stations. These adjustments may be made based on network traffic, traffic buffering times, data priorities, data length, and data rates.

摘要： The creation, modification, and deletion of a traffic stream 224 with parameterized QoS expectations between two communicating stations 205 and 207, when there is no built-in mechanism for support of parameterized QoS expectations, requires signaling of traffic characteristics and QoS parameters between the management entities such as SME 212 and MLME 214 and between the MAC entities of the communicating stations 205 and 207. Either the station 205 and 207 or a hybrid coordinator may initiate the signaling. The end result of the signaling is the creation of a new traffic stream that is used to associate user traffic to a particular set of traffic characteristics and QoS parameters, which are then used in the scheduling of the transmission of the user traffic. Another end result of the signaling is the modification of an existing traffic stream in terms of its traffic characteristics and QoS parameters.

摘要： A wireless network, including a plurality of network elements such as a wireless access point (9), and computer stations (2, 4, 6), is disclosed. The wireless network operates so that each network element (2, 4, 6, 9) waits for a pseudo-randomly selected duration, after the end of a frame on the channel, before initiating transmission. One of the network elements, such as the wireless access point (9), measures the performance of the network over a measurement period (T), and adjusts a minimum value of the upper limit of the range from which the random duration is selected, according to the performance of the network over the measurement period. The times measured may be the successful transmission time (Ts), which is maximized in adjusting the minimum value, or the idle and collision times (T1, Tc), which are equated in the optimization of the minimum value.

摘要： A method and a system for a quality of service (QoS) point coordinator (PC) for a basic service set (BSS) in a wireless local area network (WLAN) is disclosed. The PC includes a QoS management entity (QME) and an admission control entity (ACE). The QME receives at least one reservation request message that characterizes one of a QoS session and a QoS application (session/application) that can be of a continuoustperiodic flow type that is time sensitive, or can be of a discontinuous/bursty flow type that is time tolerant. The reservation request message contains at least one QoS parameter set and requests a resource of a communication channel in the BSS for the QoS session/application. The communication channel is organized into superframes, such that each superframe includes a contention-free period (CFP) and a contention-period (CP). The reservation request message requests apredetermined bandwidth of each CFP of the communication channel in the BSS. The ACE performs macro bandwidth management for QoS traffic transport of the session/application over a medium access control (MAC) sublayer for the communication channel by determining whether to grant the reservation request based on at least one QoS parameter set associated with the session/application.

摘要： A method and apparatus for providing destination discovery in a wireless network by “press and play” allows for simple transfers of data such as streaming media between a source and a destination device. The transfer can occur directly between the devices or via a piconet controller (PNC). The destination discovery method is started by activating a RX button in a destination device and a TX button in the source device without requiring the user to explicitly specify the destination address. The destination device broadcasts discovery request commands and the source device responds with discovery response commands. An RXButton timeout timer and a TXButton timeout timer are used to control the discovery process.

摘要： Each of a plurality of nodes in a wireless network is capable of generating, transmitting, and receiving beacons in a distributed fashion. Each beacon contains information regarding the order of which other nodes are to transmit beacons and wireless medium access information as to when various nodes are to access the network. Nodes that are in separate “extended neighborhoods” are permitted to transmit their beacons simultaneously without risking beacon collisions. The beacons contain information that is used to ensure this result. Using the distributed beacon mechanism, each node can reserve access to the wireless medium. In the disclosed embodiments, a central coordinator is not needed.
