A gateway interface between the public switched telephone system (PSTN) and cellular network. The gateway interface provides a conversion function between the SMS text messaging protocol and TD device text messaging protocol. The conversion function includes appropriate queuing and timing features that allow the SMS and TD functions to communicate. In an embodiment of the invention, the method and apparatus is implemented as a stand-alone gateway. The gateway may be implemented anywhere there is access to the public switched telephone network (PSTN) and coverage by a cellular system having short messaging service (SMS) capability.
