  • SS7 gateway
    Patent number: 5966431
    Abstract: The present invention telecommunications system provides validation of authorization codes input by a user for placing a call from a service area of a first telecommunications service provider with a calling card issued by another telecommunications service provider. The present invention allows the subscriber to place a special service call irrespective of whether the signaling protocol of the first service provider is different from the service provider to which the subscriber is a customer of. If the protocol of one telecommunications service provider is indeed different from the other service provider, a gateway residing in an intelligent service network node would convert the signaling protocol of the first service provider into a signaling protocol that is compatible with the other service provider.
