1. A method of allocating a system bandwidth in a satellite communication system comprising a multi-beam satellite providing satellite communication services to a service area, comprising:

  • determining a first bandwidth demand for one or more first subscriber beams serving a first subscriber beam coverage area and a second bandwidth demand for one or more second subscriber beams serving a second subscriber beam coverage area;

    dividing the system bandwidth for the first subscriber beam coverage area into a first portion of the system bandwidth used by the one or more first subscriber beams and a second portion of the system bandwidth used by a first gateway beam associated with a first gateway located within the first subscriber beam coverage area; and

    dividing the system bandwidth for the second subscriber beam coverage area into a third portion of the system bandwidth used by the one or more second subscriber beams and a fourth portion of the system bandwidth used by a second gateway beam associated with a second gateway located within the second subscriber beam coverage area,wherein the first portion of the system bandwidth used by the one or more first subscriber beams and the third portion of the system bandwidth used by the one or more second subscriber beams are based on the first bandwidth demand compared to the second bandwidth demand,and wherein the first portion of the system bandwidth used by the one or more first subscriber beams overlaps at least partially with the fourth portion of the system bandwidth used by the second gateway beam, and wherein the second portion of the system bandwidth used by the first gateway beam overlaps at least partially with the third portion of the system bandwidth used by the one or more second subscriber beams.
