Methods, systems, and computer program products for providing inter-carrier IP-based connections using a common telephone number mapping architecture

摘要

A system includes a network entry point configured to receive and process internet protocol (IP) based connection requests originating from outside the communications network, and a telephone number mapping (ENUM) database configured to store a uniform resource identifier (URI) of the network entry point and to respond to a request for routing information for a subscriber terminal within the communications network received from a remote entity outside the communications network by providing a naming authority pointer resource (NAPTR) record including the URI of the network entry point to the remote entity in response to the request for routing information.

1. A system comprising:
a network entry point to receive and process internet protocol based connection requests originating from outside a communications network; a tier 2 telephone number mapping database that is accessible from outside the communications network and that is to store a uniform resource identifier of the network entry point and to respond to a request for routing information for a subscriber terminal within the communications network received from a remote entity outside the communications network by outputting a naming authority pointer resource record including the uniform resource identifier of the network entry point to the remote entity in response to the request for routing information wherein the uniform resource identifier of the network entry point is different than a uniform resource identifier of the subscriber terminal; and a private telephone number mapping database to store internal routing information for subscriber terminals in the communications network and to respond to requests for routing information from entities within the communications network.
