Transmission control protocol/internet protocol (TCP/IP) packet-centric wireless point to multi-point (PtMP) transmission system architecture
DC CAFC
First Claim
1. A method comprising:
- coupling one or more subscriber customer premise equipment (CPE) stations with a base station over a shared wireless bandwidth using a packet-centric protocol; and
allocating said wireless bandwidth and system resources based on contents of packets to be communicated over said wireless bandwidth, wherein the contents of each packet include a packet header and wherein the allocating is responsive to at least one field in the packet header.

Abstract
A system and method are disclosed comprising coupling one or more subscriber customer premise equipment (CPE) stations with a base station over a shared wireless bandwidth using a packet-centric protocol; and allocating the wireless bandwidth and system resources based on contents of packets to be communicated over the wireless bandwidth. The packet-centric protocol may comprise transmission control protocol/internet protocol or user datagram protocol/internet protocol. The method may include allocating the shared wireless bandwidth among the subscriber CPE stations so as to optimize end-user quality of service. In one embodiment, a system comprises a wireless MAC layer mediating local retransmission of lost packets without signaling TCP lost packets and without altering TCP transmission speed, the MAC layer also scheduling packet transmissions across a wireless medium employed by a wireless network.

10. A base station comprising:
-
an interface with a first data network configured to provide communication between said base station and a first data network using a packet-centric protocol; and a controller configured to allocate wireless bandwidth and base station resources based on contents of packets to be communicated from and to said first data network with one or more subscriber CPE stations over a shared wireless bandwidth using said packet-centric protocol, wherein the contents of each packet include a packet header and wherein the controller is configured to allocate the wireless bandwidth responsive to at least one field in the packet header. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
