Abstract

The problems with reaching unavailable mobile telephones, and the unnecessary costs associated therewith are avoided by a) marking as unavailable a wireless telephone to which a wireless telephone call could not successfully be completed; b) waiting for the wireless telephone to register, i.e., signal its availability to receive calls; and c) notifying the caller of the wireless telephone call that could not successfully complete that the wireless telephone is now available. Optionally, any call attempts to the wireless telephone during this waiting period are disallowed, i.e., no attempt is made to contact the wireless telephone over the wireless telephone service provider's network. Furthermore, resources of the wireless telephone service provider may be conserved, and unnecessary costs avoided, by disallowing call attempts to the wireless telephone during the waiting period, even if the caller of the wireless telephone call that could not successfully complete is not notified of the availability of the wireless telephone upon its registration. Additionally, if the wireless telephone shares communication facilities with a wireless data station, no attempt is made to transfer data to or from the wireless data station during the waiting period. Instead, the data is queued and the queued data is transmitted after the registration is received.
