1. A method for admitting new service requests having quality of service requirements on a wireless data network having quality of service parameters comprising:
- receiving a service request having quality of service requirements from a mobile station;
estimating a load on the wireless data network using a recursive estimator to provide a load estimate;
determining an effective bandwidth of the service request;
determining that the quality of service parameters of the wireless data network satisfy the quality of service requirements of the service request;
granting the service request;
applying a discrete adjustment, based on the effective bandwidth of the service request, to the load estimate using the recursive estimator; and
monitoring the load on the wireless data network using the recursive estimator so that a deviation from the effective bandwidth of the service request and the admitted new service is eliminated.

Abstract
A method for allowing new traffic on a wireless data network. A service request is received from a mobile station (100). An effective bandwidth of the service request is estimated (110) using a recursive estimator (400). If there is enough surplus capacity on the wireless data network to accommodate the service request, the service request is granted. In response, a discrete adjustment, based on the effective bandwidth, is applied (160) to the recursive estimator (400).

10. An apparatus for allowing new traffic on a wireless data network comprising:
-
a receiver to receive a service request from a mobile station having an effective bandwidth;
a transmitter to transmit an admission grant to the mobile station; and
a recursive estimator to provide a load estimate which is an estimate of a load on the wireless data network and, responsive to the admission grant, to make an adjustment to the load estimate based on the effective bandwidth of the service request, said recursive estimator further adapted to monitor the load on the wireless data network so that a deviation from the effective bandwidth of the service request and the admitted new service is eliminated.
