Abstract
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a CIC value field in signaling information of a communication to provide an identification of the ingress network to an egress or receiving network of a long distance telecommunications network. The system and method provides for the provisioning of a signaling CIC for an ingress trunkgroup or network to a telecommunications network for downstream signaling purposes by overriding a received CIC value with a provisioned CIC value specific to the ingress network. This provisioned CIC value identifies the ingress network to the long distance network to the egress network for use by the egress network.
Claims19
A method for routing a communication in a telecommunications network, the method comprising:
- receiving a communication from an ingress network to a telecommunications network, the communication comprising a upstream carrier identification code (CIC) value associated with an upstream network;
- replacing the upstream CIC value with a provisioned ingress network specific CIC value in the communication;
- and
- transmitting the communication to an egress network of the telecommunications network with the provisioned ingress network specific CIC value in the communication.
A networking device comprising:
- at least one communication port for receiving a communication from an ingress network to a telecommunications network, the communication comprising a upstream carrier identification code (CIC) value associated with an upstream network;
- a processing device;
- and
- a computer-readable medium connected to the processing device configured to store information and instructions that, when executed by the processing device, performs the operations of:
- replacing the upstream CIC value with a provisioned ingress network specific CIC value in the communication;
- and
- transmitting the communication to an egress network of the telecommunications network with the provisioned ingress network specific CIC value in signaling information of the communication.
A telecommunications network comprising:
- an ingress device receiving a communication from an ingress network to a telecommunications network, the communication comprising a upstream carrier identification code (CIC) value associated with an upstream network;
- and
- a routing engine in communication with the ingress device providing an egress network identification for the received communication, wherein the ingress device:
- replaces the upstream CIC value with a provisioned ingress network specific CIC value in the communication;
- and
- transmits the communication to the egress network based at least on the received egress network identification with the provisioned ingress network specific CIC value in signaling information of the communication.
