Abstract: A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal. The beams that should be used are the beams that if used will decrease the call dropping rates and provide a desired level of beam source diversity.

Abstract: Methods and apparatuses for managing inter-satellite handovers are provided to allow a user terminal to reduce the frequency of handovers while maintaining a sufficiently high system capacity in a non-geosynchronous satellite communication system. The method and apparatus for managing inter-satellite handovers may be implemented in a gateway, in infrastructure connected to a gateway, in a user terminal, or in a satellite.

Abstract: Un procedimiento que comprende: conformar una disposición de haces que comprende un conjunto de haces (1-16) de una antena de un satélite en una huella del satélite (702), teniendo cada haz una primera mediana y una segunda mediana, siendo cada haz estrecho a lo largo de su primera mediana y ancho a lo largo de su segunda mediana, en el que las primeras medianas son sustancialmente colineales entre sí y las segundas medianas se orientan sustancialmente de este a oeste; y reducir la potencia a un subconjunto del conjunto de haces (8, 9, 10, 11), en el que cada haz en el subconjunto se reduce a o por debajo de un nivel de potencia correspondiente, de modo que cuando se aumenta la potencia de un haz por encima de su nivel de potencia correspondiente, una densidad de flujo de potencia equivalente supera un límite especificado en algún punto de la superficie terrestre.
