| 1. An apparatus for providing quality of service for the transmission of data packets from a base station in a wireless network
to a plurality of mobile stations in a coverage area of said wireless network, said apparatus comprising:
a packet discriminator to receive data packets from a plurality of user devices requesting to transmit data packets to said
mobile stations, wherein said packet discriminator determines whether each of said data packets is associated with one of
a real time application and a non-real time application;
a real time traffic packet processor capable of receiving from said packet discriminator first selected data packets determined
to be associated with real time applications;
a non-real time traffic packet processor capable of receiving from said packet discriminator second selected data packets
determined to be associated with non-real time applications; and
a transmission scheduler capable of scheduling transmission of the first selected data packets and the second selected data
packets by determining which of the first selected data packets and the second selected data packets has a highest scheduled
priority based upon a type of application associated with a packet, a number of packets awaiting transmission to a mobile
station associated with said packet, a measured quality of a wireless link to said mobile station, and a determination of
whether said packet is being retransmitted to said mobile station.
