Telecommunications network with multipoint communications satellite beams and an operating center determines transmission parameters according to the position of ground terminals

摘要

A network (100) of telecommunications for establishing radiofrequency links between at least one station (102) in main land connected to a center (105) operating said network (100) and terminals (106) ground using a satellite (103 ) telecommunications multipoint beam, known as a satellite multipoint dondedicha network 5 (100) comprises: - a satellite (103) multipoint, - at least one station (102) in main land, - a set of terminals (106) earth, - a coverage area comprised of a plurality of cells in which are located dichosterminales (106) on the ground, where each cell is associated with at least one spot beam with dichosatélite where it is assigned a frequency band, - one center (105) operating said network (100) connected to said station (102) in main land, wherein said network (100) is characterized in that said center (105) operating comprises: - means (108) to determine, at all moment, par meters characteristic transmission laposición of said ground terminals in said coverage area, known as means deoptimización, wherein said transmission parameters cover all of said coverage area, - means (107, LMA, LDA) to transmit to each of said terminals (106) in tierratodos transmission parameters determined by said optimization means, wherein each of said terminals (106) in earth comprising: - means (113) for determining its own geographical position in said coverage area, - means (112) for storing at least a portion of said set of transmission parameters, - means (114) for determining transmission parameters to be used by said terminal (106) buries from the stored part of said set of parameters dedicha transmission and from geographical position.
