摘要： The present Spectrum Sharing System implements spectrum reuse between aircraft-based Air-To-Ground (ATG) communication systems and Geostationary Satellite Service systems. This is accomplished by managing the radio frequency transmissions in the volume of space in which the aircraft operates, with interference between the Spectrum Sharing System and the Geostationary Satellite Service system being reduced by implementing reversed uplink and downlink radio frequency paths in the common spectrum. The Spectrum Sharing System also avoids interfering with Geostationary Satellite Services' earth stations which are pointed towards the satellites' orbital arc by relying upon a combination of the earth stations' highly directive antenna patterns and the Spectrum Sharing System ground station antenna pattern, and to avoid interfering with satellites in their orbital arc by assuring that power levels radiated in that direction by the Spectrum Sharing System ground stations are below the level that would create interference.

摘要： The Multi-Link Aircraft Cellular System makes use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques to improve the call handling capacity of the Air-To-Ground cellular communications network. These additional techniques can include polarization domain and ground antenna pattern shaping (in azimuth, in elevation, or in both planes). Further, if code domain separation is added, dramatic increases in capacity are realized. Thus, the Air-To-Ground cellular communications network can increase its capacity on a per aircraft basis by sharing its traffic load among more than one cell or sector and by making use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques.

摘要： A remote coverage system extends the effective coverage area of a cellular mobile radiotelecommunications (CMR) master cell. When a mobile unit assigned to the master cell moves from the master cell's coverage area into the coverage area of a satellite cell, the satellite cell sends a signal asking for a handoff of the mobile unit to it. When the handoff occurs, the MTSO exchanges signals with the mobile unit via a relay unit located at the master cell site. The relay unit relays signals between the MTSO and the satellite cell.

摘要： A technique for enabling a peregrinating Cellular Mobile Radiotelephone (CMR) subscriber to automatically receive, in a foreign service area (that is, an area outside his home service area), calls placed to his MID at his home service area. A roaming processor is coupled through a cable or LAN to a switch associated with a foreign MTSO and is coupled, preferably through a private data network, to a switch associated with the subscriber's home MTSO. Within the roaming processor resides a program that detects the reception at the foreign switch of a predetermined code indicating that calls placed to the roamer's home MID are to be forwarded to the foreign MTSO. Subsequent to the "validation" of the roamer and to the performance of certain software housekeeping tasks, the roamer is assigned a Temporary Directory Number (TDN) for use in the remote service area. The FMR processor then commands the subscriber's home MTSO switch to forward calls, placed to the subscriber's MID at the home MTSO, to the TDN. Calls are subsequently forwarded, via the PSTN, from the subscriber's home MTSO to the foreign MTSO.

摘要： The present Broadband Link System supplements the existing Air-To-Ground Radio Frequency communications link with an additional, separate high speed Broadband Ground-To-Air Data Channel to provide additional data communication capacity for aircraft. This Broadband Ground-To-Air Data Channel is typically a uni-directional (Ground-To-Air) link directed via a focused beam to selected aircraft which are operational in the coverage area of the Broadband Ground-To-Air Data Channel. The routing of the various data transmissions on both the Air-To-Ground Radio Frequency communications link and the Broadband Ground-To-Air Data Channel are managed in a unified manner to maximize the utilization of the two transmission facilities.
