Carrier Identification Code Delivery to Egress Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications networks do not effectively utilize Carrier Identification Codes (CIC) for downstream signaling purposes, leading to unnecessary retention of routing information throughout the entire transmission, even after it becomes obsolete.
Innovation Solution
A method and system for provisioning and delivering an ingress-specific carrier identification code (CIC) to an egress network in a telecommunications network, where the upstream CIC value is removed and replaced with a provisioned ingress network-specific CIC value in the signaling information of the communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upstream CIC value is retained in the communication throughout the entire transmission, then the routing information is preserved for all network segments, but the CIC becomes obsolete and unnecessary for downstream devices after the communication reaches the network
Solution Approach 1:
The patent segments the CIC information handling into distinct phases: the upstream CIC is retained and utilized during the ingress portion of the communication path, then replaced with a downstream CIC for the egress portion. This segmentation allows each network segment to have the appropriate routing information without carrying obsolete data throughout the entire transmission path.
Solution Approach 2:
The patent changes the CIC parameter from a static value retained throughout transmission to a dynamic value that is replaced at the network boundary. The upstream CIC is removed and a provisioned downstream CIC is inserted, transforming the routing information parameter to match the needs of different network segments.
2Device complexity
If the upstream CIC value is discarded by devices along the communication path, then the communication path is simplified, but downstream devices lose valuable information about the originating network
Solution Approach 1:
The patent introduces an intermediary mechanism where the network acts as a mediator between the upstream and downstream segments. The network removes the upstream CIC and inserts a provisioned downstream CIC that encodes information about the originating network, thereby preserving valuable information while simplifying the communication path for downstream devices.
Solution Approach 2:
The patent creates a copy of the routing information in a transformed format. Instead of discarding the upstream CIC or passing it unchanged, the network creates a new downstream CIC that copies the essential information about the originating network in a form suitable for downstream devices.
3Device complexity
If the CIC is not utilized for downstream signaling purposes, then the signaling system remains simple, but billing procedures require delayed Call Detail Records
Solution Approach 1:
The patent performs preliminary action by provisioning and inserting the downstream CIC value before the communication is transmitted to the egress network. This advance preparation ensures that billing and signaling information is immediately available when the communication arrives at the destination, eliminating the need for delayed Call Detail Record processing.
Solution Approach 2:
The communication signal itself carries the billing and signaling information through the provisioned CIC value, allowing the system to self-serve billing requirements without requiring separate delayed processing. The CIC embedded in the communication provides immediate information for billing purposes.

AI summary
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.
