`ABSTRACT
`
`An IP flow classification system is used in a wireless
`telecommunications system. The IP flow classification sys(cid:173)
`tem groups IP flows in a packet-centric wireless point to
`multi-point telecommunications system. The classification
`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 communication with
`the wireless base station over a shared bandwidth using a
`packet-centric protocol; and one or more subscriber work(cid:173)
`stations coupled to each of the subscriber CPE stations over
`a second network; a resource allocation device optimizes
`end-user quality of service (QoS) and allocates shared
`bandwidth among the subscriber CPE stations; an analyzing
`and scheduling device analyzes and schedules internet pro(cid:173)
`tocol (IP) flow over the shared wireless bandwidth. The
`analyzing device includes the above IP flow classifier that
`classifies the IP flow. The classifier can include a device for
`associating a packet of an existing IP flow with the IP flow.
`The classifier can include a QoS grouping device that groups
`a packet of a new IP flow into a QoS class grouping. The
`QoS grouping device can include a determining device that
`determines and takes into account QoS class groupings for
`the IP flow. The QoS grouping device can include an
`optional differentiated services (Diff Serv) device that takes
`into account an optional Diff Servs field priority marking for
`the IP flow.
