These embodiments provide communications between a space-based component and the first radiotelephone over substantially the first frequency band and/or the first air interface and between the space- based component and the second radiotelephone over substantially the second frequency band and/or substantially the second air interface. It will be understood that embodiments of the present invention may be provided as systems and/or methods.

  • other embodiments of the invention may be configured to enable use of an increased or maximum number of time slots per forward GSM carrier frame, to provide a higher downlink data rate to the radiotelephones.
  • the return link vocoder may need to be comparable with quarter-rate GSM, while the forward link vocoder can operate at full- rate GSM, to yield six full-duplex voice circuits per GSM TDD-mode carrier (a voice capacity penalty of 25%).
  • the modified second range of satellite band forward link frequencies includes a plurality of frequencies in the second range of satellite band forward link frequencies that are transmitted by the ATCs to the radiotelephones at a power level, such as maximum power level, that monotonically decreases as a function of (increasing) frequency.
  • Embodiments of Figure 9 may be regarded as idealized because they associate concentric ring areas with carrier frequencies (or carrier frequency sets) used by an ATC to serve its area. In reality, concentric ring areas generally will not be the case. For example, a radiotelephone can be close to the ATC that is serving it, but with significant blockage between the radiotelephone and the ATC due to a building. This radiotelephone, even though relatively close to the ATC, may also request maximum (or near maximum) output power from the ATC. With this in mind, Figure 10 may depict a more realistic set of area contours that may be associated with the frequencies being used by the ATC to serve its territory, according to embodiments of the invention.

In yet other embodiments, the lower power slots may be used with first selected ones of the radiotelephones that are relatively close to the ATC and/or are experiencing relatively small signal blockage, and the remaining slots are transmitted at higher power to second selected ones of the radiotelephones that are relatively far from the ATC and/or are experiencing relatively high signal blockage.

  • substantially the same air interface means that the air interfaces are similar but need not be identical.
  • FIG 16 is a schematic diagram of satellite radiotelephone systems and methods according to some embodiments of the invention. As shown in Figure 16, these embodiments of satellite radiotelephone systems and methods include a space-based component 1610 that is configured to communicate with radiotelephones 1620a-1620c in a satellite footprint 1630 that is divided into a plurality of satellite cells 1640a-1640c. It will be understood by those having skill in the art that, although three satellite cells 1640a-1640c and three radiotelephones 1620a-1620c are illustrated in Figure 16, satellite radiotelephone systems and methods according to embodiments of the present invention may employ more than three satellite cells 1640a-1640c and may employ more than three radiotelephones 1620a-1620c.
