| 20090017847 | Buddy-Based Cross-Carrier Messaging System - A buddy-based, cross-carrier mobile phone based text messaging server, system and method is disclosed. A table of subscribers cross referenced against buddy subscribers who have opted in to receive text messages (SMS) is maintained. Where a recipient subscriber is not yet registered as a buddy subscriber, the server sends a message asking if the recipient subscriber wants to become a buddy subscriber of the sending subscriber. If the recipient subscriber opts-in, the recipient subscriber is added to the table as a buddy subscriber, and thereafter will be forwarded all messages through the service, sent from the particular sending subscriber, until the buddy subscriber opts-out. The invention ensures a near one to one correspondence of in/out SMS for participating mobile phone networks, and avoids any one network being overloaded with spam messaging. | 01-15-2009 |
