Carrier identity translation for special service calls based on the organization responsible for the special service routing database

摘要

In a communication system, a call processing system receives a first signaling message for a special service call indicating a special service number. The call processing system processes the special service number to determine a first carrier identity and an organization identity for a responsible organization that is responsible for a routing database system for the special service number. The call processing system processes the organization identity for the responsible organization to select a second carrier identity. The call processing system transfers a second signaling message that indicates the second carrier identity. In some examples, a communication node receives the second signaling message and processes the second carrier identity to route the special service call to the responsible organization.

1. A method of operating a communication system to perform carrier identity translation on special service telephony calls, the method comprising:
in a call processing system, receiving a first signaling message for a special service call indicating a special service number; in the call processing system, processing the special service number to determine a first carrier identity and a Responsible Organization (RespOrg) for a routing database system for the special service number; in the call processing system, processing the RespOrg to select a second carrier identity; and in the call processing system, transferring a second signaling message that indicates the second carrier identity to a communication node, wherein the communication node processes the second carrier identity to route the special service call to the RespOrg.
