Abstract

A system and a method for securing telecommunications resources include a resource requirements module which determines network resource requirements specified in call requests of telecommunications calls. In one embodiment, a resource availability monitor determines if the resource requirements exceed the available levels for at least two network resources. In another embodiment, the resource availability monitor determines if Digital Signal Processor (DSP) requirements in the call request exceed DSP availability. If the resource requirements exceed the resource availability at the time when the call request is received, a resource reservation mechanism places the call request into network resource queues for those network resources which are in short supply. When the call request reaches the front of one of the network resource queues, the resource reservation mechanism reserves the network resource for a predetermined time interval and determines whether all resource requirements for the call request can be satisfied. If so, the call is established. If any resource requirements cannot be satisfied within the predetermined time interval, the reserved resources are released to provide the next call request in the queue the opportunity to reserve the network resources. If all resource requirements are satisfied, a call setup subsystem establishes the call.
