Abstract

"APARELHO E MéTODO PARA ALOCAçãO EFICIENTE DE LARGURA DE FAIXA TDMA PARA REDES BASEADAS EM SATéLITE TCP/IP". Um sistema de comunicação equilibra tráfego de mensagens entre grupos de canal de retorno e dentro dos grupos, de modo que o usuário não controle a freq³ência específica de transmissão usada. Freq³ências de ligação ascendente e larguras de faixa para os canais de retorno são estabelecidas pelo sistema em uma mensagem de controle de canal de retorno no sinal de difusão de modo a responder pelo carregamento do sistema e do grupo de canal de retorno, e responder por registros posteriores de mensagens de usuário. Uma transmissão inicial de um usuário remoto pode ser feita utilizando um sinal de rajada tipo ALOHA que provê um registro posterior de mensagem para a estação de controle/ e é feita em uma freq³ência determinada de um processo para seleção de freq³ência baseado em carga aleatoriamente ponderada. O sistema, e não os usuários individuais, determina as alocações de canal e freq³ência. Para grandes registros posteriores ou usuários de prioridade, é fornecida largura de faixa periódica. Um método para balancear cargas dentre e entre grupos de canais de retorno no sistema de comunicação inclui solicitar largura de faixa de canal de retorno em uma mensagem de ligação ascendente de um usuário remoto para uma estação de controle. A mensagem de ligação ascendente pode incluir tanto um indicador de registro posterior como uma solicitação de alocação de largura de faixa fornecida a um Centro de Operações de Rede (NOC) o qual pode ser utilizado para estabelecer a freq³ência e largura de faixa de canal de retorno para a ligação ascendente remota. Uma mensagem de usuário é transmitida na freq³ência de canal de retorno designada utilizando largura de faixa alocada de acordo com o indicador de registro posterior e uma solicitação de alocação de largura de faixa de modo que cargas de tráfego sejam mantidas em equilíbrio entre grupos de freq³ência de canal de retorno estabelecidos, e dentro de cada grupo de freq³ência de canal de retorno."APPLIANCE AND METHOD FOR EFFICIENT ALLOCATION OF TDMA BAND WIDTH FOR NETWORKS BASED ON SATELLITE TCP / IP". A communication system balances message traffic between return channel groups and within groups, so that the user does not control the specific transmission frequency used. Uplink frequencies and bandwidth widths for the return channels are established by the system in a return channel control message in the broadcast signal in order to respond to the loading of the system and the return channel group, and to account for registers. subsequent user messages. An initial transmission from a remote user can be made using an ALOHA burst signal that provides a backlog of message to the control station / and is done at a determined frequency of a process for frequency selection based on randomly weighted load. The system, not individual users, determines channel and frequency allocations. For large backup records or priority users, periodic bandwidth is provided. A method for balancing loads between and between groups of return channels in the communication system includes requesting return channel bandwidth in an uplink message from a remote user to a control station. The uplink message can include both a backlog indicator and a request for bandwidth allocation provided to a Network Operations Center (NOC) which can be used to establish the frequency and return channel bandwidth. for the remote uplink. A user message is transmitted on the designated return channel frequency using allocated bandwidth according to the backlog indicator and a request for bandwidth allocation so that traffic loads are kept in balance between frequency groups. established return channels, and within each return channel frequency group.
