Abstract
A telecommunication system and method of signalling are disclosed which enable service providers to integrate broadband network capability into their existing narrow band networks while being substantially transparent to existing narrow band signalling infrastructures such as the Common Channel Signalling System Number 7 (CCS7), currently in use. Significant advantages are realized through such a network system. Service providers, for example incumbent local exchange carriers (ILECs) now have access to BB connectivity while retaining the use of their extensive CCS7 signalling networks and Advanced Intelligent Network (AIN) resources. Investment in the CCS7 signalling infrastructure is hence not lost and the proven robustness and reliability of these networks is retained. Service providers can continue to take advantage of Intelligent Network capabilities in providing a large variety of voice services, but also to make available some of the current service features for future BB services. Furthermore each network is virtually independent of the other and can evolve as such. Telephony service call related signalling is able to be kept separate from the broadband network connectivity signalling thus allowing service providers to evolve their service specific signalling requirements independently of whatever BB networks are used now or in the future.
