Nonterrestrial cellular mobile telecommunication network
First Claim
1. A telecommunication system for providing cellular radio communication with non-terrestrial mobile subscriber stations using radio frequencies allocated for ground-based mobile telecommunications, comprising:
- at least one radio transmitter for generating communication signals transmitted to non-terrestrial mobile subscriber stations at radio frequencies allocated for ground-based mobile subscriber stations, said generated communication signals comprising control and user data signals;
at least one radio receiver for receiving communication signals generated by said non-terrestrial mobile subscriber stations at radio frequencies allocated for said ground-based mobile subscriber stations, said received communication signals comprising control and user data signals; and
wherein said communication signals generated by said at least one radio transmitter and said non-terrestrial mobile subscriber stations comprise at least one channel for exchanging control signals, said at least one channel being selected to contain control signals incapable of being used by said ground-based mobile subscriber stations.

Abstract
The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.
