Patent ID: 7414969

Claim:
In a IEEE 802.11 network, a method for periodic stream admission control, the method comprising: at an access point (AP), receiving a transmit specification, including a requested bandwidth, from a quality of service station (QSTA); converting transmit specification parameters into time; computing T temp , the transmission time equivalent to the requested bandwidth and Ttxop, the duration of the transmission opportunity in each poll in response to: the network physical layer (PHY) parameters including the short interframe spacing (Tsifs), the PCF interframe spacing (Tpifs), and the slot duration (Tslot); the duration of the poll frame (Tpoll), wherein Tpoll is calculated in response to the duration of the preamble (Tpreamble), the time occupied by the signal field in the PLCP header on the channel (Tsignal), and the duration of the OFDM symbol (Tsymbol); the probability of pollframe transmission success (q 2 ); and, the duration of each transmission (Ttx); computing T all , the transmission time already allocated; computing T res , the total transmission time available; if T temp +T all <T res , admitting the QSTA; and, if T temp +T all >T res , not admitting the QSTA.
