Abstract

An adaptation sublayer is provided between LAC/MAC and a Packet Data Service Node for a Code Division Multiple Access telecommunication system. Quality of Service parameters are defined and stored within a Base Station and Base Transceiver Station along with subscriber profiles, including class of service. The profiles include specified Quality of Service requirements for each subscriber profile. A Quality of Service Adaptation Layer provides logic and control means to identify each active subscriber, provide the associated Quality of Service and direct the active subscriber'"'"'s communication connection to a target host.
