In some implementations, a satellite transceiver receives a data structure that specifies an interference compensation value for at least one frequency channel on which the satellite transceiver can transmit. The interference compensation value for the frequency channel is based on estimated interference imposed on satellite transmissions transmitted by the transceiver on the frequency channel. The transceiver receives data specifying a second transmit frequency channel to use for a second satellite transmission. A first interference compensation value for a first frequency channel and a second interference compensation value for the second frequency channel are identified from the data structure.

    Abstract: A network node communicates with a radio access node that communicates application traffic on behalf of machine-to-machine (M2M) devices via a satellite link. The network node comprises a database and a control unit. The database stores a plurality of recovery modes. Each recovery mode indicates one or more types of application traffic that M2M devices are or are not allowed to transmit when operating according to that recovery mode. The control unit detects a loss of communication across, or congestion on, the satellite link, selects one of the recovery modes, and requests the radio access node to broadcast the selected recovery mode over a 3GPP-based broadcast channel in order to instruct the M2M devices to transmit only application traffic allowed in accordance with the selected recovery mode.

  • Publication number: 20150118955
    Abstract: Systems and methods for problem signature terminal diagnosis are disclosed. In an example embodiment, measured operational statistics of a satellite terminal of a peer group of satellite terminals are received and converted into normalized operation statistics. Normalized deviations of the operational statistics are determined and compared to the threshold deviations. A diagnosis zone corresponding to a problem signature is determined based on the normalized deviations by determining that coordinates of the normalized deviations are within the diagnosis zone, comparing a ratio based on the normalized deviations to a threshold ratio, or comparing a differential of the normalized deviations to a threshold differential. A satellite terminal is diagnosed with a problem defined by the problem signature based on the determined diagnosis zone.

  • Patent number: 8995905
    Abstract: A wireless network relay apparatus includes a Layer 2 switch and a line control device as well as wireless/wired line terminating devices performing band limitation associated with an AMR function. It measures traffic passing through each line terminating device in inflow/outflow path directions. Upon detecting a modulation scheme changed due to an AMR function in a wireless area, it may specify a line terminating device so as to read a desired modulation scheme from a transmission source modulation scheme conversion table of the line control device based on traffic. It may change a local modulation scheme with a desired modulation scheme when a difference therebetween is above a predetermined number of stages. By tracking a modulation scheme changed for a transmission destination, it is possible to appropriately change a modulation scheme for a transmission source, thus suppressing traffic without discarding necessary data.

  • Patent number: 8954000
    Abstract: Systems and methods for real-time signal validation are disclosed. In an example embodiment, a subset of terminals in a peer group of satellite terminals is determined. Operational statistics of the satellite terminals in the subset of terminals is measured. Operational statistics of each of the satellite terminals in the subset of terminals is compared to a prior measurement of the same operational statistics. An offset between a current measurement of the operational statistics and the prior measurement of the same operational statistics is determined. An average offset of the current measurement of the operational statistics and the prior measurement of the same operational statistics is determined for the subset of terminals. The average offset for the subset of terminals is merged with a previously determined peer group operational statistic. A signal validation of a terminal is performed using an updated deviation value.
