Abstract
Unnecessary expenses associated with exchanging data with wireless data stations that have become unavailable are avoided, in accordance with the principles of the invention, by a) transmitting the data to be transmitted to a store and forward unit; b) marking as unavailable a wireless data station to which the store and forward unit could not successfully complete the data transmission; c) waiting for the wireless data station to register, i.e., signal its availability to receive data transmissions; and d) transmitting the data from the store and forward unit to the data station once a registration is received from the wireless data station. Optionally, any data transfers to the wireless data station during this waiting period are queued at the store and forward data unit and no attempt is made to contact the wireless data station over the wireless service provider's network. Furthermore, if the data station shares communication facilities with a wireless voice telephone, any call attempts to the wireless telephone during the waiting period are disallowed, i.e., no attempt is made to contact the wireless telephone over the wireless service provider's network.
