Abstract:
1. A method of providing reverse link admission control with quality of service differentiation in a wireless communication system, utilizing a reverse link interference metric and a long-term sector loading metric measured over a period of time, comprising the steps of: evaluating a first set of preconditions to determine whether or not sufficient resources are available for a new call to be admitted and rejecting the new call if the first set of preconditions is not satisfied; admitting a new call if the first set of preconditions is satisfied and the reverse link interference metric is below a first threshold for the reverse link interference metric; rejecting a new call if the first set of preconditions is satisfied and the reverse link interference metric is above a second threshold for the reverse link interference metric; and evaluating, where the first set of preconditions is satisfied and the reverse link interference metric is between the first and second thresholds, the long-term sector loading metric measured over the period of time to selectively admit or reject a new call, wherein the long-term sector loading metric further comprises a load estimation that comprehends a ratio of traffic channel power to pilot channel power and a busy time ratio, and wherein the step of evaluating the long-term sector loading metric further comprises determining whether a projected load is less than a third threshold derived from the thresholds of the reverse link interference metric, wherein the projected load equals a sum of current load, load change on existing elastic flows, and an estimated load addition by the new call.
