  • Patent number: 6707901
    Abstract: One of the features of the Intelligent Network (IN) is the storage of subscriber profile information at network databases, such as, but not limited to, service control points (SCPs) and Home Location Registers (HLRs.) Such profiles may also be stored at the local switch level, and be made accessible to all other nodes via the signaling network. The present invention extends service logic functionality for a given subscriber to allow for the interaction of subscriber profiles on behalf of a single subscriber, and sharing of data contained in these profiles, to enhance single-ended, single point-of-control services specific to either the calling or called party offered in an Intelligent Network. As such, an enhanced service tailored to both the called and calling parties is made available.
