Monitoring the noise condition in the distributed antenna system 10 includes monitoring one or more remote units 14 of the plurality of remote units and determining if the remote unit is active status or mute status and then. The uplink gain is increased in response to a decrease in the number of remote units that are active status and decreased in response to an increase in the number of remote units that are active status.

  • Patent number: 9107228
    Abstract: A communication system includes a plurality of nodes including a base station; at least one terminal; and at least one relay node through which each terminal can be connected to the base station. An entity in a network higher in layer than each relay node configures the relay node to set a target value for a predetermined parameter reflecting a radio link status of the relay node. The relay node monitors the predetermined parameter to notify an upper-layer node of difference information corresponding to a difference between the target value and a monitored parameter value. The upper-layer node controls a link parameter of a radio link connecting the upper-layer node and the relay node depending on the difference information, resulting in efficient radio resource allocation in a relay network with small signaling overhead.

  • Patent number: 9026036
    Abstract: The invention is directed to a method and system for supporting wireless RF services over a wired digital data network infrastructure, such as an Ethernet network. The system includes a control unit that can be connected to a base station that supports one or more wireless RF services. The control unit converts the wireless RF signals to an intermediate frequency (IF) that does not interfere with the data network signals and combines the IF signals onto the cable run to a remote network device on the digital data network. The remote network device includes a multiplexer or a low pass filter and a high pass filter that separates the IF signals from the digital data signals on the downlink and combines the IF signals with digital data signals on the uplink over the cable run. The IF signals can be input to an RF module connected to the remote network device which converts the IF signals back to the original RF signals for transmission by a transceiver to wireless devices.

  • Publication number: 20150118954
    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.

    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.
