Abstract

A system for routing short messages between message centers provides that messages are first checked to see if they are to be handled by the local message center, and then routed, if appropriate, to another message center using point code or global title translation routing.

Claims

1. A method of processing a short message in an SS7 network, comprising:

receiving a short message at a local message center computer system;

checking a message center subscriber database in the computer system to determine if the message is addressed to the message center such that the message is to be delivered under control of the message center;

if the message is not addressed to the local message center, looking for the address of the destination message center in a message center routing table in the computer system;

if the address is in the routing table, routing the message to the destination message center according to a point code addressing; and

if the address is not in the routing table, routing the message to the destination message center by global title translation addressing.

2. A method according to claim 1 further including the step of the local message center attempting to directly deliver a short message which could not be delivered to its proper destination message center.

3. A program product comprising a computer program encoded in a machine readable medium, the computer program including program code executable on a suitably configured computer to process a short message in an SS7 network, according to the following steps:

receiving a short message at a local message center computer system;

checking a message center subscriber database in the computer system to determine if the message is addressed to the message center such that the message is to be delivered under control of the message center;

if the message is not addressed to the local message center, looking for the address of the destination message center in a message center routing table in the computer system;

if the address is in the routing table, routing the message to the destination message center according to a point code addressing; and

if the address is not in the routing table, routing the message to the destination message center by global title translation addressing.

4. A product according to claim 3 further wherein the computer code is operative on the computer to attempt to directly deliver a short message which could not be delivered to its proper destination message center.

5. A computer system for processing short messages in an SS7 network, comprising:

a hardware platform;

one or more software components executing on the hardware platform for

checking a local message center subscriber database in the computer system to determine if the message is addressed to the local message center such that the message is to be delivered under control of the message center;

if the message is not addressed to the local message center, looking for the address of the destination message center in a message center routing table in the computer system;

if the address is in the routing table, routing the message to the destination message center according to a point code addressing; and

if the address is not in the routing table, routing the message to the destination message center by global title translation addressing.

6. A product according to claim 5 further wherein the computer program components include code which is operative on the computer to attempt to directly deliver a short message which could not be delivered to its proper destination message center.
