Abstract: A system reduces the number of blocked and abandoned calls in a wireless communication system. A cell site receives a call from a wireless station and determines that no available resources exist. In response thereto, the blocked cell site sends a retry message to the wireless station to redirect the call back to the originally blocking face of the cell site.

Abstract: A method for controlling the admission of a call into a service area. The method includes the steps of selecting a non-negative integer N; selecting a real number p, lying between 0 and 1 inclusive; admitting a call when N−2 or fewer channels are occupied; blocking the call with a probability p when N−1 channels are occupied; and blocking the call when N or more channels are occupied.
