Abstract
A quality of service (QoS) aware, wireless point to multi-point telecommunications system includes: a wireless base station coupled to a first data network; one or more host workstations coupled to the first data network; one or more subscriber customer premise equipment (CPE) stations in wireless communications with the wireless base station over a shared bandwidth wireless medium using a packet-centric protocol; one or more subscriber workstations coupled to each of the subscriber CPE stations over a second network; and a resource allocation device that allocates shared bandwidth among the subscriber CPE stations to optimize end-user quality of service (QoS) for an IP flow.

13. A quality of service (QoS) aware, wireless point to multipoint telecommunications system comprising:
-
a wireless base station coupled to a first data network;
one or more host workstations coupled to said first data network;
one or more subscriber customer premise equipment (CPE) stations in wireless communication with said wireless base station over a shared bandwidth wireless medium using a packet-centric protocol;
one or more subscriber workstations coupled to each of said subscriber CPE stations over a second network; and
resource allocation device that allocates said shared bandwidth wireless medium among said subscriber CPE station to optimize end user quality of service (QoS) for an IP flow, wherein said resource allocation device comprises means for assigning future slots of a transmission frame to a data packet in the transmission frame for transmission over said shared bandwidth wireless medium, and wherein said assigning means comprises;
means for applying an advanced reservation algorithm;
means for reserving a first slot for a first data packet of an Internet Protocol (IP) flow in a future transmission frame based on said algorithm;
means for reserving a second slot for a second data packet of said IP flow in a transmission frame subsequent in time to said future transmission frame based on said algorithm, wherein said second data packet is placed in said second slot in an isochronous manner to the placing of said first data packet in said first slot. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A quality of service (QoS) aware, wireless communications system comprising:
-
a wireless access point base station coupled to a first data network;
one or more host workstations coupled to said first data network;
one or more wireless network stations in wireless communication with said wireless access point base station over a shared wireless network using a packet-centric protocol; and
a scheduler that allocates resources of said shared wireless network among said wireless network stations to optimize end-user quality of service (QoS) for an Internet Protocol (IP) flow, wherein said IP flow is associated with at least one of a latency-sensitive and a jitter-sensitive application;
wherein said scheduler comprises assigning means for assigning future slots of a transmission frame to a portion of said IP flow in said transmission frame for transmission over said shared wireless network, wherein said assigning means comprises;
means for applying an advanced reservation algorithm;
means for reserving a first slot for a first data packet of an Internet Protocol (IP) flow in a future transmission frame based on said algorithm;
means for reserving a second slot for a second data packet of said IP flow in a transmission frame subsequent in time to said future transmission frame based on said algorithm, wherein said second data packet is placed in said second slot in an isochronous manner to the placing of said first data packet in said first slot. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
