Method and apparatus supporting short message services in a wireless number portability environment
First Claim
1. A method for transmitting a message in a network from an originating system, the message destined for a subscriber, wherein a directory number (DN) is assigned to the subscriber, and wherein the subscriber is served by a destination system including a message center (MC), the method comprising the steps of:
- routing the message from the originating system to a first node in the network;
identifying the DN in the message;
translating the DN to an address associated with a second node in the network;
routing the message to the second node based on the address;
translating, at the second node, the DN to a point code associated with the destination MC; and
routing the message to the destination system using the point code.

Abstract
In a Wireless Number Portability (WNP) environment, a scheme is provided for routing and delivering Short Message Service (SMS) messages. In a WNP environment, the mobile identification number (MIN) and mobile directory number (MDN) will become independent, and the existing method of routing SMS messages will be inadequate to provide SMS to subscribers that port from one service provider to another. Methods and systems for delivering SMS messages to ported subscribers are provided.

3. A system for transmitting a message in a network from an originating system, the message destined for a subscriber, wherein a directory number (DN) is assigned to the subscriber, and wherein the subscriber is served by a destination system including a message center (MC), the system comprising:
-
a database;
means for routing the message from the originating system to a first node in the network;
means for identifying the DN in the message;
means for translating the DN to an address associated with a second node in the network configured to access the database;
means for routing the message to the second node based on the address;
means for translating the DN to a point code associated with the destination system MC; and
means for routing the message to the destination system MC using the point code. - View Dependent Claims (4)
