Abstract

There is provided a method for improving an allocation of resources, i.e., frequency and power, to terrestrial services and satellite services that use a same frequency band. The method includes determining a demand (D_S) for a resource by users of a satellite system, determining a demand (D_T) for the resource by users of a terrestrial system, and allocating the resource between the satellite system and the terrestrial system based on a ratio of D_S to D_T.

11. The method of claim 1,

wherein said satellite system comprises a non-geosynchronous satellite constellation, and

wherein method further comprises repeating said determining said D_S, determining said D_T, and said allocating, after a positional change of said constellation.

12. The method of claim 1,

wherein said satellite system comprises a satellite telecommunications system, and

wherein said terrestrial system comprises a cellular telecommunications system.

13. The method of claim 1, wherein said users of said satellite system and said users of said terrestrial system are located in a beam of a satellite in said satellite system.

14. The method of claim 1, wherein said terrestrial system includes a transmitter having a non-directional antenna.

15. The method of claim 1, further comprising denying said satellite system use of a frequency band in a beam of a satellite of said satellite system if a number of users of said terrestrial system located in said beam and using said frequency band is greater than a threshold number.

16. The method of claim 1, further comprising denying said satellite system use of a frequency band in a beam of a satellite of said satellite system if D_T in said beam and using said frequency band is greater than a threshold demand.
