Carrier identity translation for special service calls based on the organization responsible for the special service routing database
View Patent ↗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.
2. The method of claim 1 wherein communication node comprises at least one router.
3. The method of claim 1 wherein the RespOrg does not have a corresponding carrier identity.
4. The method of claim 1 wherein the first carrier identity indicates a wireless communication network.
5. The method of claim 1 wherein the first carrier identity and the second carrier identity indicate a wireless communication network and the second carrier identity is associated with the RespOrg in the wireless communication network.
6. The method of claim 1 wherein the special service call comprises a toll-free call.
7. The method of claim 1 wherein at least one of the first carrier identity and the second carrier identity comprise a Carrier Identification Code.
8. The method of claim 1 wherein the RespOrg comprises a Responsible Organization (RespOrg) code.
9. The method of claim 1 wherein at least one of the first signaling message and the second signaling comprises a signaling system 7 message and wherein the call processing system comprises a service control point.
10. A telephony computer apparatus to facilitate carrier identity translation on special service telephony calls, the apparatus comprising:
telephony software instructions configured, when executed by a telephony computer system, to direct the telephony computer system to process a first signaling message for a special service call indicating a special service number, process 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, process the RespOrg to select a second carrier identity, and initiate 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; and
at least one computer-readable non-transitory storage medium storing the telephony software instructions.
11. The telephony computer apparatus of claim 10 wherein the first carrier identity and the second carrier identity comprises Carrier Identification Codes and wherein the RespOrg comprises a Responsible Organization (RespOrg) code.
12. The telephony computer apparatus of claim 10 wherein the first signaling message and the second signaling message comprise signaling system 7 messages and wherein the telephony computer system comprises a service control point.
13. A communication system to translate carrier identity on special service telephony calls, the system comprising:
a call processing system configured to receive a first signaling message for a special service call indicating a special service number, process 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, process the RespOrg to select a second carrier identity, and transfer a second signaling message that indicates the second carrier identity; and
a communication node configured to receive the second signaling message and process the second carrier identity to route the special service call to the RespOrg.
14. The communication system of claim 13 wherein the communication node comprises at least one router.
15. The communication system of claim 13 wherein the RespOrg does not have a corresponding carrier identity.
16. The communication system of claim 13 wherein the first carrier identity indicates a wireless communication network.
17. The communication system of claim 13 wherein the first carrier identity and the second carrier identity indicate a wireless communication network.
18. The communication system of claim 13 wherein the first carrier identity and the second carrier identity comprises Carrier Identification Codes and wherein the RespOrg comprises a Responsible Organization (RespOrg) code.
19. The communication system of claim 13 wherein the first signaling message and the second signaling message comprise signaling system 7 messages and wherein the call processing system comprises a service control point.
