Intelligent source routing for mobile handset message service providers

1. A return message routing method for a mobile handset message system to facilitate identification of the correct return path for messages initially passing through a gateway from email or other electronic text or graphics message transmission device interfaced customers to message enabled mobile handset customers; the routing method comprising the steps of:

a) providing a routing system associated with a gateway; the system having a predetermined number of output lines each having a different calling line identifying number (CLID);

b) identifying the target telephone number for each incoming message received by the system;

c) routing each successive incoming message directed to the same target mobile handset through a different calling line identifying number based upon a predetermined pattern of usage in which the calling line identifying numbers are to be utilized;

d) storing a return path associated with each calling line identifying number and associated with each message which is dispatched from that number to a target mobile handset;

e) receiving a return message from a mobile handset at the same calling line identifying number which dispatched the original message and recalling the source of the original message which passed through that calling line identifying number;

f) routing the return message from the mobile handset to the originating source destination via an appropriate protocol converter.

2. A return message routing method in accordance with claim 1 hereof wherein the mobile handset message system is comprised of mobile cell phones in conjunction with the existing SMS protocol.

3. A return message routing method in accordance with claim 1 hereof wherein the predetermined number of output lines exceeds the number of messages that may be stored in individual target mobile handsets.

4. A return message routing method in accordance with claim 1 hereof wherein the pattern is time based such that a sequence of CLID usage by the system referable to a particular target handset is observed until the expiry of a time limit whereupon the sequence of CLID usage is repeated or an alternate sequence of usage commenced.

5. A return message routing method in accordance with claim 1 hereof wherein the pattern is a closed loop such that CLIDs are initially utilized in accordance with a predetermined sequence and after exhaustion of available CLIDs for a target handset the CLIDs are reused in a predetermined sequence.

6. A return message routing method in accordance with claim 1 hereof wherein the message originators are email interfaced to the gateway of the system.

7. A return message routing method in accordance with claim 1 hereof wherein the message originators are interfaced to the system via a web page utilizing HTTP protocol.
