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.
Claims17
A method for providing a pre-defined quality of service to a wireless transmission, said method comprising:
- receiving a wireless transmission at a base station connected to a wireless network;
- providing a quality of service application interface for controlling said wireless transmission between said wireless network and radio link resources;
- storing pre-defined quality of service parameters for data transmissions within a wireless telecommunications system;
- providing different levels of quality of service in either forward or reverse data traffic direction;
- utilizing said pre-defined quality of service parameters to classify data transmissions within said wireless telecommunication system by
- selecting a radio link class of a mobile unit transmitted signal based on a QoS-f class;
- and
- selecting a radio link class of a network transmitted signal based on a QoS-r class;
- and
- directing said data transmissions, having an identified requirement, to a target radio link control resource within said wireless telecommunication system.
An apparatus for providing a pre-defined quality of service to a wireless data transmission, said apparatus comprising:
- a wireless telecommunications network;
- a base station connected to said wireless network for receiving said wireless data transmission;
- a quality of service application interface for controlling said wireless data transmission between said wireless network and radio link resources;
- pre-defined quality of service-parameters for associating with said wireless data transmissions in said wireless telecommunications network, wherein said pre-defined quality of service further includes
- means for selecting a radio link class of a mobile unit transmitted signal based on a QoS-f class;
- and
- means for selecting a radio link class of a network transmitted signal based on a QoS-r class;
- logic means for providing different levels of quality of service in either forward or reverse data traffic direction;
- logic means for classifying data transmissions in said wireless network utilizing said pre-defined quality of service parameters;
- and
- transmission means for directing said data transmissions, with an identified classification, to a different quality of service control based on a desired quality of service for said wireless data transmission.
A computer program product residing on a computer usable medium associated with a wireless telecommunication network for providing a pre-defined quality of service to a wireless data transmission, said computer program product comprising:
- program code means for receiving said wireless data transmission at a base station connected to said wireless telecommunication network;
- program code means for providing different levels of quality of service in either forward or reverse data traffic direction;
- program code means for providing a quality of service application interface for controlling said wireless data transmission between said wireless network and radio link resources;
- program code means for storing pre-defined quality of service parameters for associating said parameters with said wireless data transmissions;
- program code means for utilizing said pre-defined quality of service parameters to classify data transmissions in said wireless telecommunications network, wherein said program code means for utilizing said pre-defined quality of service parameters further includes
- program code means for selecting a radio link class of a mobile unit transmitted signal based on a quality of service-forward class;
- and
- program code means for selecting a radio link class of a network transmitted signal based on a quality of service-reverse class;
- and
- program code means for directing said wireless data transmissions, with an identified classification, to a different quality of service control based on a desired quality of service for said wireless data transmission.
