Abstract:
A method of preempting active calls traversing an ATM switch or ATM node in favor of an inactive call during connection admission control, comprising:a) for each active call, storing a first indication of a precedence level assigned to that active call and carried in a call message used to establish that active call such that a plurality of first indications are stored;b) determining a second indication of a precedence level assigned to the inactive call and carried in a call message used in attempting to establish the inactive call;c) comparing said second indication with at least one of said plurality of first indications; andd) when said comparing indicates that said second indication indicates a relatively higher precedence than at least one of said plurality of first indications, designating said inactive call for acceptance, and designating at least one of said active calls having a first indication of relatively lower precedence than said second indication for preemption.
