Number portability in a communications system
DCFirst Claim
1. A method of operating a signaling processor for a call having a signaling message and a user communication, the method comprising:
- receiving the signaling message for the call indicating a called number;
processing the called number to transfer a number portability query;
receiving a number portability response indicating a route number;
processing the route number to select an identifier for routing the user communication; and
transferring a control message indicating the user communication and the identifier to a communication system, wherein the communication system, in response to the control message, adds the identifier to a header of the user communication and routes the user communication based on the identifier in the header.

Abstract
A communication system is disclosed comprised of a signaling processor and an interworking system. The signaling processor receives a call setup message including a called number, processes the called number to transmit a query, receives a response message responsive to the query that includes number portability information for the called number, processes the number portability information to select an identifier for routing, and transmits a control message that identifies the identifier. The interworking system receives a user communication and the control message, converts the user communication into communications that include the identifier, and transfers the communications that include the identifier.

11. A signaling processor for a call having a signaling message and a user communication, the method comprising:
-
an application configured to process a called number from the signaling message to generate a number portability query, process a route number from a number portability response to select an identifier for routing the user communication, and generate a control message indicating the user communication and the identifier; and a platform configured to receive the signaling message, transfer the number portability query, receive the number portability response, and transfer the control message to a communication system, wherein the communication system, in response to the control message, adds the identifier to a header of the user communication and routes the user communication based on the identifier in the header. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
