Abstract: A system, method, and call processing component for controlling an order of call processing among a plurality of call processing components. Each call processing component, upon receiving a call request when system resources are not available to process the requested call, creates a real queue entry in its call processing queue and sends a call-queued notification to all other call processing components in the system. The other call processing components in the telecommunication system then create a shadow queue entry in their respective call processing queues as a placeholder for the requested call. When system resources become available and the requested call is next in the queue, the call processing component that received the request de-queues and processes the requested call, and sends a call de-queued notification to the other call processing components.

Abstract: An entity of a wireless telecommunications network having a pool of Mobile Switching Centers (MSCs) and a Home Location Register (HLR). The entity includes a network interface which sends pages to mobiles associated with a failed MSC of the pool of MSC's and experiencing termination isolation and receives responses to the pages from at least some of the mobiles. The entity includes a processing unit which produces a registration having updated location information for each response received by the network interface, the registration sent from the network interface to the HLR to end each mobile's termination isolation for which a response was received by the network interface. A method of an entity of a wireless telecommunications network having a pool of Mobile Switching Centers (MSCs) and a Home Location Register (HLR).
