Patent ID: 7565161

Claim:
A method of processing a call request received in a wireless network having an active call allocation system in place, the method comprising: determining whether radio traffic channel resources are available for the call request without involving a queue when at least one traffic channel can accommodate the call right away; where radio traffic channel resources are available without involving a queue, allowing the call request to go through; where radio traffic channel resources are not available without involving a queue, determining whether the call request is for a priority call; and where the call request is for a priority call: initially creating a queue for each radio traffic channel resource type potentially applicable to the call per cell sector available in the network and for each queue thus created; determining whether the queue is full; where the queue is not full, adding the priority call to the queue; where the queue is full, determining whether the queue has an existing call request of lower priority; where the full queue does not have an existing call request of lower priority, not entering the request in this queue and aborting the priority call request if the network is not able to enter the request to any queue; and where the full queue does have an existing call request of lower priority: displacing the existing call request of lower priority; aborting the displaced call if it is not in another queue; and adding the new call request to the queue with position determined by priority and time.
