Abstract
In a cellular communication system where satellite nodes are moving with respect to the earth's surface, frequencies and time-slots are dynamically reallocated between cells in response to demand for services. When a particular cell is at or near its capacity because of a high demand for services, or is projected to be at or near capacity, spectral capacity is reallocated from nearby cells to meet the increase in demand. The reallocation in capacity is based on both real time cell loading data and historical cell loading information based on previous experiences.
