Number portability in a communications system
DC CAFCFirst Claim
1. A method for operating a communications system, the method comprising:
- receiving a call setup message including a called number into a signaling processor;
processing the called number in the signaling processor to transmit a query;
receiving a response message responsive to the query that includes number portability information for the called number;
processing the number portability information to select an identifier for routing;
transmitting a control message that indicates the identifier;
receiving a Time Division Multiplex (TDM) user communication and the control message into an interworking system;
converting the TDM user communication into packet communications that include the identifier for routing; and
transferring the packet communications that include the identifier for routing.

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.
