ABSTRACT:
A number of different mechanisms are proposed for effectuating the delivery of digital data messages to mobile stations which have currently selected an analog control channel. In one method, a signal is sent to the mobile station instructing it to make a server reselection and choose the best available digital control channel. Once the reselection is accomplished, the digital data message is delivered in a conventional manner using the digital control channel. In another method, the digital data message is reformatted for analog delivery, and the reformatted message sent over either the analog control channel or a selected analog voice channel. In yet another method, a call connection is made with the mobile station over a voice channel, and a synthesized audible message corresponding to the digital data message is transmitted over the voice channel after the subscriber answers the call. In instances where message delivery over the control channel is interrupted due to mobile station roaming, a forced re-registration occurs following the new server reselection, thus triggering continued message delivery over the new control channel.
