摘要： A communication system having a proxy architecture is disclosed. The system includes a platform that provides performance enhancing functions. The platform includes a backbone connection apparatus that routes information within a communication system. The backbone connection apparatus receives backbone connection parameters from the platform and maintains the current parameters in one or more backbone connection profiles. The backbone connection apparatus routes packets of information throughout the communication system based on the backbone connection profile. The backbone connection apparatus supports the use of different backbone protocol for different types of backbone links. Further, in a configuration where multiple backbone links of different types exist, the backbone connection apparatus supports the use of a different backbone protocol for each type of link at the same time. The above arrangement has particular applicability to a bandwidth constrained communication system, such as a satellite network.

摘要： An onboard DAMA protocol for use in connection with a processing satellite communications network, where multiple users are assigned to a common transmission resource as part of a sharing set. A media access controller (30) on the satellite maintains a reservation log which identifies the frequencies and number of uplink time slots in the resource that are currently reserved by one or more members of the sharing set. To reserve a time-frequency slot on the transmission resource for a non-contentious transmission of data, a user of the sharing set will transmit a reservation request to the satellite on a contentious uplink resource. If a return message is not received, the user knows that the reservation request collided with another reservation request, and a retransmission strategy of the reservation request is employed. When the media access controller (30) receives the reservation request, it decides whether to grant, deny or delay the request based on the service and price class of the user, the amount of data already sent by the user, the number and type of other users with reservation requests in the queue, and the congestion state of the destination downlink port and subsequent nodes in the network. When the user receives a reservation grant message from the media access controller (30) on the satellite in the downlink, it will then wait for its reservation time frequency slot, and transmit its data in a non-contentious basis on the transmission resource at that time. If the user needs additional bandwidth to transmit more data, it may piggyback a reservation request on the data transfer.

摘要： A distributed demand assigned multiple access control scheme (22) for use in connection with a processing satellite communications system, where multiple users are assigned to a common TR as part of a sharing set (12). The control scheme (22) of the invention makes use of a reservation procedure by transmitting set addressed reservation messages in a contentious control flow to reserve data transfer time in a non-contentious main flow. Each user of the sharing set is synchronized with each other and with a known synchronization variable defined by the next available uplink time slot available to transmit data in the main flow (10). When a user of a sharing set wishes to send data in the main flow, it transmits the set addressed reservation message in the control flow (26), and if the set addressed reservation message is returned in the satellite downlink (28), the terminal knows that all of the users of the shared set received the message. That reserved time interval in the main flow is now owned by that user, and each user in the shared set updates its next available uplink time slot based on the reserved time. By gaining access to the shared set, each user is limited to a predetermined peak cell rate, is guaranteed a sustained cell rate, and is limited to a maximum reservation length. The maximum reservation length identifies the largest number of data units transmitted per reservation, and defines a worst case delay that the user must wait to gain a reservation. A user may piggyback a reservation by sending a set addressed reservation message during transmission of data in the main flow.

摘要： A system and method for allocating one or more portions of the frequency spectrum among a plurality of radio frequency (RF) transmitters and/or receivers. The system comprises a hub station that dynamically allocates the frequency spectrum in response to demand of the plurality of RF transmitters and/or receivers. Based on the demand, the hub station analyzes the state of performance of one or more groups of RF transmitters and/or receivers, and optimizes utilization of the assigned frequency spectrum.

摘要： An approach for immediate channel assignment in a wireless communications system involves receiving a channel request message from a wireless transceiver, the channel request message including a dialed party number; forming an immediate assignment message including a channel assignment; transmitting the immediate assignment message to the wireless transceiver; and establishing a communications channel between the wireless transceiver and a called party by establishing a channel between the wireless transceiver and the called party.

摘要： An Internet system includes an original server (1a-1n) that transmits its contents to a platform server (3). The platform server (3) collects the contents, and broadcasts them to receivers (5a-5n) through satellite channels (13 and 13') via a communications satellite (4). When the contents transmitted from a satellite Internet subnetwork (101) includes contents requested by user terminals (6a-6n), the receivers (5a-5n) select the desired contents, and deliver them to the user terminals (6a-6n). When the contents do not include the desired contents, the receivers (5a-5n) receive them from a CATV Internet subnetwork (102) or a terrestrial Internet subnetwork (103), and delivers them. Thus, the Internet system can automatically selects the channels in response to the traffic of the channels or to the desired contents.

摘要： A system for managing return channel bandwidth in a two-way satellite communication network is disclosed. A plurality of transceivers (109) are configured to transmit backlog information over a return channel via a satellite (107). The backlog information specifies an amount of queued traffic for the respective transceivers (109). A hub (113) is configured to receive the backlog information and to allocate a predetermined amount of return channel bandwidth to each of the plurality of transceivers (109). The hub (113) determines whether additional return channel bandwidth is available to accommodate a remaining backlog such that a bandwidth allocation amount is set to a level associated with one of the plurality of transceivers (109) having the largest backlog. The hub (113) selectively identifies a transceiver (109) among the plurality of transceivers (109) having a next largest backlog based upon the determined available return channel bandwidth. The hub (113) selectively adjusts the bandwidth allocation amount to a level associated with the transceiver (109) with the next largest backlog. The hub (113) allocates the additional return channel bandwidth to the plurality of transceivers (109) based upon the adjusted bandwidth allocation amount if the adjusted bandwidth allocation amount reduces at least a portion of the backlog of the plurality of transceivers (109).
