Abstract
Communication session admission control systems and methods are disclosed. A state of a communication system is monitored, and admission of a communication session into the communication system is controlled based on a random admission control procedure and a current state of the communication system. Monitoring of the current state of equipment in the communication system, connections in the communication system, communication sessions in progress in the communication system, special monitoring sessions established in the communication system, and/or an overall state of the communication system can have several benefits. These benefits may include improving utilization of resources in the system, and providing a session admission control scheme that is capable of reacting to actual observed conditions and adapting to changing system topologies following a fault, for instance. Random admission control further avoids all or nothing session blocking, which can have the undesirable effect of prompting a high number of session retries.
