20110134876 | Wireless Communication System, Wireless Communication Device, and Wireless Resource Management Method - It is provided a base station for providing a wireless communication area, which is coupled to a core network via a gateway, including: an interface for receiving settings of availability of allocation to terminals located in a border area of the wireless communication area and availability of allocation to terminals located in an area other than the border area for each of radio resource blocks which are defined by dividing radio resources available for use in the wireless communication area provided by the base station into predetermined units; and a plurality of profiles for defining scheduling limitations on the radio resources in the number of the profiles of patterns, being set via the interface, in which the base station applies scheduling limitations defined by the profile designated with the identifier and allocates the radio resources upon designation of one of the plurality of profiles with an identifier. | 06-09-2011 |
20110182196 | NETWORK SYSTEMS, NETWORK INTERCONNECTION DEVICES, AND DATA TRANSMISSION SCHEME - A network system includes one or more terminals which transmit acquired data to a first network, a network interconnection device which is connected to the terminal via the first network and which receives the data from the terminal, and a management server which is connected to the network interconnection device via a second network and which receives the data from the network interconnection device; the terminal transmits the same data to the network interconnection device via the first network by a frequency corresponding to redundancy; the data contains the priority according to the contents of the data; and the network interconnection device acquires the communication quality of the second network and instructs the terminal to transmit the data according to redundancy determined based upon the acquired communication quality and the priority. | 07-28-2011 |
20110287791 | Wireless Communication System and Communication Control Method - It is provided a wireless communication system comprising base stations that communicate with a terminal. Each of the base station has antennas. Each of the base stations transmits a first reference signal unique to each of the antennas which does not overlap with another antenna among the base stations at least in a vicinity thereof. The terminal receives the first reference signal and estimates a received power of the first reference signal for each of the antennas, selects antennas suitable for communication from among the antennas based on a result of estimating the received power, and transmits a result of selecting the antennas to the each of the base stations. The each of the base stations refers the result of selecting the antennas transmitted from the terminal, assigns the selected antennas belonging to different cells to the terminal, and notifies the terminal of a result of assigning the antennas. | 11-24-2011 |
20110287798 | Base Station and Wireless Communication System - It is provided a wireless communication system comprising base stations that transmit data to a terminal with cooperation by the base stations. The terminal communicates with the base stations. The terminal periodically transmits, to one of the base stations, information necessary for data transmission from a single base station out of the base stations. Each of the base stations determines whether the terminal needs data transmission through a cooperation among the base stations, and transmits a cooperation information transmission instruction to the terminal, which includes information necessary to execute the data transmission in order to cooperate among the base stations in the case where it is determined that the terminal needs the data transmission through the cooperation among the base stations. The terminal transmits the cooperation information to the base stations in a case of receiving the cooperation information transmission instruction. | 11-24-2011 |
20120317278 | COMMUNICATION APPARATUS, COMMUNICATION METHOD AND REMOTE MONITORING SYSTEM - In a remote monitoring system including a monitoring center, a sensing information collecting station, and one or more sensing terminals, the sensing information collecting station collects measurement results measured by the sensing terminals, classifies the collected measurement results into priority information and general information, and transmits priority information and general information to the monitoring center. The monitoring center transmits response information to received priority information to the sensing information collecting station. The sensing information collecting station estimates network condition from a delay time based on the response information and decreases the transmission rate of general information when the estimated network condition is more congested. Thereby, even if the network condition fluctuates, desired information such as statistical information on measurement results and measurement results meeting a predetermined condition is communicated stably at low delay. | 12-13-2012 |
20120320928 | MONITORING SYSTEM, DEVICE, AND METHOD - Provided is a monitoring system which can perform priority control in accordance with the wideband limitation. A priority/filter type selection processing unit ( | 12-20-2012 |

20130185417 | REMOTE MONITORING SYSTEM, NETWORK INTERCONNECTION DEVICE AND COMMUNICATION CONTROL METHOD - Even though a network with communication rate large fluctuations is applied to a remote monitoring system, data communication delay time is kept smaller for which a shorter communication delay time is demanded and a high throughput is implemented. A sensor equipped terminal sends measurement data to a network interconnection device. A priority level determining unit of the device sorts the data into first data necessary to be delivered to a monitoring center within requested communication delay time and second data not necessarily to be delivered to the center within requested communication delay time. A transmission buffer unit is a buffer storing the first and second data accumulated in first and second data accumulating units in sending the data to a wide area network by FIFO. A transmission control unit dynamically controls a rate in causing the data to come in the transmission buffer unit based on a network communication rate. | 07-18-2013 |
