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.

Abstract: A system and method for protocol translation. The system includes an SS7 Module for sending and receiving a plurality of incoming and outcoming SS7 queries and response. The system also includes an Inbound Subsystem Module, coupled to the SS7 Module, for translating the incoming SS7 queries from a SS7 protocol to a non-SS7 protocol. The translated incoming queries are forwarded to an end user while in the non-SS7 protocol. The Inbound Subsystem Module also translates any responses corresponding to the incoming SS7 queries from the non-SS7 protocol to the SS7 protocol. The system further includes an Outbound Subsystem Module, coupled to the SS7 Module, for translating outgoing SS7 queries from the non-SS7 protocol to the SS7 protocol. The translated outgoing queries are sent via the SS7 module across an SS7 network. The Outbound Subsystem Module also translates SS7 responses corresponding to the outgoing SS7 queries from the SS7 protocol to the non-SS7 protocol.
