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.

System and method for redirecting calls to blocked cell sites

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&minus;2 or fewer channels are occupied; blocking the call with a probability p when N&minus;1 channels are occupied; and blocking the call when N or more channels are occupied.

Probabilistic use of wireless reserve channels for admission control

A cellular communication system (10) includes any number of land stations (12), each of which controls a cell (14). When channels are assigned to cells (14), a figure of merit which predicts potential voice quality, such as C/I, is determined (34) for each channel/cell assignment. The assigned channels and associated figures of merit are distributed to corresponding land stations (14) to make channel-to-cell assignments. When a call arises in a cell (14) a channel is selected for assignment to the call. The channel is selected from channels assigned during the channel-to-cell assignment phase. A channel assignment algorithm (68) ensures that potentially lower quality channels (20) are the least used channels at the cell (14). When potentially lower quality channels (20) are assigned to calls, the calls are handed off to potentially higher quality channels (18) as soon as potentially higher quality channels (18) become available.
