  • Method and apparatus for providing a communications service feature for a communication through a network
    Patent number: 7903799
    Abstract: A method and apparatus for providing a communications service feature to a party communicating through a network. It is first determined if the party making the communication is a subscriber based on an identifier associated with the party and a local database containing a subset of subscriber identifiers. It is then verified that the identifier associated with the party is in the subset of identifiers that would be included in this local database. For those identifiers that are not in the local database and that are not in the subset of identifiers that would be included in the local database, a global database containing all subscriber identifiers is queried to determine if the party is a subscriber. It can also be verified that the network provider knows the identifier of the party making the communication and that the provider is able to provide the communications service feature for the particular communication.
