Patent ID: 7852759

Claim:
One or more non-transitory computer-readable storage media embodying software operable when executed by one or more computer systems to: receive a call admission request from a wireless client seeking medium access to a wireless network; in a first state, apply a first call admission control (CAC) algorithm to the call admission request; in a second state, apply a second CAC algorithm to the call admission request; and transition between the first state and the second state based on one or more of the following equations: Na_High_Thresh = (Av/100 * (MaxCallCapacity − X)); Na_Low_Thresh = Na_High_thresh/Y + num of calls(RRv); and Na_Roam_Thresh = num of calls(RRv)/Z, wherein Na is the number of additional calls, wherein Av is the percentage of the channel allocated for voice calls, wherein MaxCallCapacity is based on the average MT (Medium Time) value of calls, wherein RRv is a percentage of channel allocated for roaming reserves for voice calls, wherein X is a user-configurable value, and wherein Y and Z are each a non-zero user-configurable value.
