Inter-network call forwarding with subscriber identity
First Claim
1. A method for processing a call placed by a calling party to a service subscriber with call forwarding to an enhanced telecommunications service platform in a telecommunications network other than the subscriber'"'"'s network, comprising the steps of:
- (a) receiving call parameters accompanying the call corresponding to a standard protocol from a service switching point (SSP) associated with the subscriber'"'"'s telephone number;
(b) causing at least one of the call parameters to be set to a value corresponding to a call data value different than a call information value prescribed for the at least one call parameter by an industry specification associated with the standard protocol; and
(c) causing the call to be forwarded with the call data value to a telephone number associated with the enhanced service platform.

Abstract
An automated intelligent network system and method for providing automatic forwarding of calls to enhanced telecommunications service platforms across network boundaries while preserving subscriber identity. In accordance with the present invention, the values of defined parameters that are maintained with a call according to established network protocols and passed between networks during call processing are controlled such that, using these controlled values, the subscriber identification information reaches the platform where the enhanced service is implemented in different network than that of the service subscriber. An alternative embodiment of the invention provides a way for enhanced telecommunications services platforms to identify both the subscriber and the calling party when calls are automatically forwarded to the platform across network boundaries.

16. An automated intelligent network system for processing a call placed by a calling party to a service subscriber with call forwarding to an enhanced telecommunications service platform in a telecommunications network other than the subscriber'"'"'s network, comprising:
-
a service switching point (SSP) associated with the subscriber'"'"'s telephone; a service control point (SCP) for receiving call parameters accompanying the call corresponding to a standard protocol from the SSP; first means for causing at least one of the call parameters to be set to a value corresponding to a call data value different than a call information value prescribed for the at least one call parameter by an industry specification associated with the standard protocol; and second means for causing the call to be forwarded with the call data value to a telephone number associated with the enhanced service platform. - View Dependent Claims (17, 18, 19)
