System and method of providing communication service using a private packet network backbone exchange

摘要

Systems and methods for providing communication service using a private packet network backbone exchange (PPNBE) are disclosed. The private packet network backbone exchange may include a logical call control entity, a logical routing database, one or more PPNBE gateways, and a private packet network. The PPNBE may provide “one-hop” call connection between a call-originating entity and a call-terminating entity without traversal of any other exchanges. The PPNBE may simultaneously support both one-hop local and long distance calls. The PPNBE architecture is easily scalable and incorporated into existing communication networks for on-net and off-net service. Methods and systems for providing access tandem communication service using a PPNBE are also disclosed.

1. A private packet network backbone exchange (PPNBE) for providing communication service, comprising:
a private packet network; and a logical call control entity in signaling communication with a plurality of exchanges, the logical call control entity coupled to a single logical routing database and configured to establish, while operating in conjunction with the single logical routing database, a one-hop communication session between two of the plurality of exchanges over the private packet network without traversing any other exchanges, the one-hop communication session including at least one of voice or data that is delivered over the private packet network, the one-hop communication session corresponding to a call, and the call is a tandem call.
