Abstract: A method for location-based communications routing includes determining a location of a requesting party in accordance with an address of the requesting party. Whether the location of the requesting party is in a first subscriber service area is determined and, when the location of the requesting party is not in the first subscriber service area, whether the location of the requesting party is in a second expanded subscriber service area larger than and including the first subscriber service area is determined. When the location of the requesting party is determined to be in the first subscriber service area, data corresponding to the first subscriber area is forwarded. When the location of the requesting party is determined to be in the second expanded subscriber service area, data corresponding to the second expanded subscriber service area is forwarded.

Abstract: A method and system include routing telephone calls from multiple private networks via public lines and trunks in a public switched telephone network (PSTN) to a host switch, at which the connections would begin to run parallel. The host switch routes the telephone calls via a private trunk group to a private facility, such as an electronic tandem network (ETN) node or an asynchronous transfer mode (ATM) switch. If the private trunk group is full or unavailable, the host switch routes the telephone calls over alternate private or public trunk groups and selected carriers.

Abstract: A communication network element determines a service provider's routing preference for routing communications and routes these communications from an originating connection address to a destination connection address over a network. The communication network element includes a receiver configured to receive a signal, which comprises the originating connection address and the destination connection address. The communication network element also includes a processor that determines the service provider associated with at least one of the originating connection address and the destination connection address of the received signal. The processor also determines the routing preference associated with the service provider using routing data.

Abstract: A method for location-based communications routing includes determining a location of a requesting party in accordance with an originating communications address of the requesting party. The method also includes determining whether the location of the requesting party is in a first subscriber service area and, when the location of the requesting party is not in the first subscriber service area, determining whether the location of the requesting party is in a second expanded subscriber service area larger than and including the first subscriber service area. When the location of the requesting party is determined to be in the first subscriber service area, a communication from the requesting party is forwarded to a routing communications address associated with the first subscriber service area.

Abstract: A telecommunications system determines a telecommunications service provider's routing preference for routing a call for a subscriber. The telecommunications system includes a storage that stores call routing data and a call routing service application for determining the routing preference using the call routing data. The call routing data includes an indicator that indicates when the subscriber subscribes to resold local switching services and when the subscriber subscribes to unbundled local switching services. The telecommunications system also includes a processor that executes the call routing service application, and that generates call routing instructions for routing the call according to the determined routing preference.

Abstract: A method, system and computer readable medium are provided for defining a service area served by a service location of a telecommunications network customer. The method includes ascertaining a geographic designator of a geographic area. The geographic area includes a plurality of geographic sub-areas that each correspond to a geographic sub-designator. The method also includes determining whether any two of the plurality of geographic sub-areas are not served by the same service location. When any two of the plurality of geographic sub-areas are not served by the same service location, the service area is defined by only the sub-designators corresponding to the geographic sub-areas served by the service location. When each of the plurality of geographic sub-areas are served by the same service location, the service area is defined by the geographic designator.
