Abstract: A ground-to-air telephone calling system is provided including a computer for receiving an airborne telephone number and a call-back number from a calling party and forming the telephone numbers into a data signal comporting with existing protocol filed in the FCC, an uplink unit for uplinking the data signal to a satellite and a plurality of downlink stations for receiving the data signal from the satellite; a plurality of ground stations corresponding to each of the downlink units for receiving the data signals and passing a call signal identifying the airborne telephone and particular ground station to a corresponding transmit/receive unit for subsequent transmission to the aircraft; a call being initiated from the ground station to the calling party over the public switched telephone network if the aircraft responds to the call signal.

Abstract: A mobile paging telephone call back device determines and adds the appropriate prefix to a received call back number. The call back device includes a pager, a control unit, an automatic dialer, and a cellular telephone. The pager receives a page message from a paging system central controller. The control unit extracts a dialable telephone number from the page message, determines the appropriate prefix to be added to the telephone number, and adds the prefix to the telephone number. Using the telephone number with the added prefix, the automatic dialer completes a call back for the cellular telephone.

Abstract: A system for establishing a communication link between a caller and a mobile communication device that includes a mobile telephone and a paging device capable of receiving information transmitted from a paging network. In addition to the mobile communication device, the system includes a telephone network, a first mobile switching center, a conference bridge, a paging network, and a second mobile switching center. The first mobile switching center receives a telephone call transmitted over the telephone network using an identification number of the mobile telephone. If the mobile communication device is not located in the area covered by the mobile switching center, the mobile switching center forwards the received telephone call to a conference bridge using a bridge number assigned to the mobile communication device. The conference bridge receives the forwarded telephone call and transmits an identification number of the paging device in the mobile communication device to the paging network.
