A method enabling a device the ability to maintain a personal distribution list (PDL), i.e., a group contact list, via manipulation of text messages sent over the SMS, with service homed on the SMSC. Each PDL is maintained on an SMSC affiliated with the list's originating device and is referenced with a trigger address, either particularly or implicitly defined. When an SMSC receives an SMS message destined to a trigger address, identifying a PDL, the SMSC copies the originally transmitted text message for every recipient in the list. The SMSC subsequently routes each duplicate text message to every address contained within the indicated PDL, via conventional SMS procedures. Syntax indicating list management operations (e.g., add, delete, list entries, and delete, synch, and/or tag entire list) may be indicated in the body of an SMS message addressed to the local address of the SMSC for list management capabilities. |
