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.

Claims (40)

1. A method for routing communication data in a telecommunications network, the method comprising:

receiving the communication data from an ingress network to the telecommunications network, the communication data comprising an upstream carrier identification code (CIC) value associated with a calling party in an upstream network;

removing the upstream CIC value from the communication data;

inserting a provisioned ingress network specific CIC value into a signaling information included in the communication data, the provisioned ingress network specific CIC value different from the upstream CIC value, and the provisioned ingress network specific CIC value indicative of the ingress network from which the communications data were received; and

transmitting the communication data including the provisioned ingress network specific CIC value in the signaling information to an egress network of the telecommunications network, wherein the provisioned ingress network specific CIC value identifies the ingress network to the telecommunications network for use by the egress network.

2. The method of claim 1 wherein the communication data comprises a time-division multiplex (TDM)-based networking communication data and the signaling information comprises a signaling system no. 7 integrated services digital network user part initial address message (SS7 ISUP IAM) message, the provisioned ingress network specific CIC value included in the SS7 ISUP IAM message.

3. The method of claim 2 wherein the signaling information further comprises a carrier identification parameter (CIP) field of the SS7 ISUP IAM message, the provisioned ingress network specific CIC value included in the CIP field.

4. The method of claim 1 wherein the communication data comprises Internet Protocol (IP)-based networking communication data and the signaling information comprises a Session Initiation Protocol (SIP) INVITE message, the provisioned ingress network specific CIC value included in the SIP INVITE message.

5. The method of claim 4 wherein the signaling information further comprises a request uniform resource indicator (R-URI) header of the SIP INVITE message, the provisioned ingress network specific CIC value included in the R-URI header.

6. The method of claim 1 further comprising:

identifying the ingress network to the telecommunications network by receiving the communication data on a trunkgroup connection to the telecommunications network, the trunkgroup connection associated with the ingress network.

7. The method of claim 6 further comprising:

provisioning the ingress network specific CIC value based on an identification of the ingress network associated with the trunkgroup connection, the ingress network specific CIC value unique to the trunkgroup connection.

8. A networking device comprising:

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, cause the processing device to perform operations of:

identifying communication data received from an ingress network to a telecommunications network, the communication data comprising an upstream carrier identification code (CIC) value associated with a calling party in an upstream network;

detecting the upstream CIC value of the communication data;

removing the upstream CIC value from the communication data;

inserting a provisioned ingress network specific CIC value into a signaling information included in the communication data, the provisioned ingress network specific CIC value different from the upstream CIC value, and the provisioned ingress network specific CIC value indicative of the ingress network from which the communications data were received; and

transmitting the communication data including the provisioned ingress network specific CIC value in the signaling information to an egress network of the telecommunications network, wherein the provisioned ingress network specific CIC value identifies the ingress network to the telecommunications network for use by the egress network.

9. The networking device of claim 8 wherein the communication data comprises a time-division multiplex (TDM)-based networking communication data and the signaling information comprises a signaling system no. 7 integrated services digital network user part initial address message (SS7 ISUP IAM) message, the provisioned ingress network specific CIC value included in the SS7 ISUP IAM message.
