Abstract

Systems and methods for providing multi-homed tandem access in a communication system are disclosed. The disclosure may include a private packet network backbone exchange (PPNBE) in connection with a set of access tandems and with a call destination such as an end-user or a communications service. A set of LRNs may be homed across the set of access tandems, with each of the set of LRNs mapped to one or more TNs corresponding to the call destination. An originating party may use any of the TNs to reach the call destination. A plurality of originating calls each including one of the TNs may be received at the PPNBE from any of the access tandems and routed to the call destination. Thus, the present disclosure provides greater call capacity than available access tandem architectures as well as optimizes a maximum number of call paths to a particular call destination.

Claims23

Dependent claims

A private packet network backbone exchange (PPNBE) for delivering a call using multi-homed access, comprising:

a private packet network;
a logical call control entity, the logical call control entity coupled to the private packet network and to a single logical routing database, and the logical call control entity in signaling communication with a plurality of access exchanges and with an endpoint to which a call is to be delivered;
an originating connection between the private packet network and each of the plurality of access exchanges;
and
a terminating connection between the private packet network and the endpoint, wherein:
the endpoint is indicated by each Terminal Number (TN) in a set of TNs,
each TN in the set of TNs corresponds to a respective LRN (Local Routing Number) in a set of LRNs,
each LRN in the set of LRNs is homed to a respective access exchange of the plurality of access exchanges,
the private packet network is configured to receive the call, the call including a selected TN from the set of TNs,
a content of the call is received by the private packet network over a corresponding originating connection from a corresponding access exchange, and
the private packet network is further configured to deliver, based on the selected TN and based on an indication from the logical call control entity in conjunction with the single logical routing database, the call from the corresponding originating connection to the terminating connection and the endpoint.

8 more elements

A method for accessing an endpoint using a multi-homed exchange, comprising:

receiving an indication of an assignment of each TN included in a set of TNs to correspond to a specific local routing number (LRN) from a plurality of LRNs;
receiving, at a computing device associated with a communications exchange, a call from one access exchange of a set of access exchanges, wherein:
the call includes a Terminal Number (TN) that is selected from the set of TNs;
each LRN of the plurality of LRNs is homed to a respective access exchange from the set of access exchanges;
and
each TN of the set of TNs corresponds to a common destination endpoint;
and
routing, by the computing device associated with the communications exchange and based on the TN and the respective LRN, the call to the common destination endpoint.
