SYSTEM AND METHOD FOR IMPROVED RESOURCE MANAGEMENT IN AN INTEGRATED TELECOMMUNICATIONS NETWORK HAVING A PACKET-SWITCHED NETWORK PORTION AND A CIRCUIT-SWITCHED NETWORK PORTION

摘要

A system and method for providing improved resource management, e.g., bandwidth re-allocation, in an integrated telecommunications network (100) having a packet-switched network portion (e.g., a Voice-over-Internet Protocol (VoIP) network portion) (104) and a cellular network portion (114). When a parametric variable associated with the number of registrations of mobile stations in a Mobile Switching Center (MSC) (114A) passes a threshold test (206), the MSC sends a message (306) to its gateway (106A), the message including a level change parameter. Responsive thereto, the gateway re-registers in a gatekeeper (110) that is provided for managing a zone in the VoIP network. The gateway includes in its registration request (308) the level change parameter received from the MSC. The gatekeeper uses the level change parameter as an input to its resource management function and re-allocates the resources available for the gateway.
