20130003597 | BASE STATION DEVICE, MOBILE STATION DEVICE, AND COMMUNICATION CONTROL METHOD - A base station device communicates with a mobile station device, either directly or via a relay station device. The base station device includes: a reference signal transmission instruction unit configured to instruct the mobile station device to transmit a reference signal; and a reference signal measurement instruction unit configured to instruct the relay station device to measure the reference signal that is transmitted by the mobile station device. | 01-03-2013 |
20130244683 | WIRELESS COMMUNICATION SYSTEM, TRANSMISSION CHANNEL SELECTION METHOD, AND TRANSMISSION CHANNEL SELECTION PROGRAM - A transmission channel selection method includes: collects information for calculating evaluation values of each of a plurality of transmission channels, and calculates separate evaluation values of the transmission channels individually with respect to each of a plurality of mobile stations; reduces the number of candidates for the transmission channels with respect to the plurality of mobile stations using the separate evaluation values; collects information for jointly calculating evaluation values of the transmission channels with respect to at least one of the plurality of mobile stations, and calculates the joint-separate evaluation values; and selects the communication paths of the plurality of mobile stations using the separate evaluation values and the joint-separate evaluation values. | 09-19-2013 |
20130329646 | WIRELESS COMMUNICATION SYSTEM, BASE STATION DEVICE, AND WIRELESS COMMUNICATION ROUTE SELECTION METHOD - A base station device includes: an information collection unit configured to collect information for calculating evaluation values for each of first, second, and third transmission paths; an evaluation value calculation unit configured to calculate the evaluation values for each of the first, second, and third transmission paths, based on the collected information; and a transmission path selection unit configured to select, using the evaluation values of each of the first, second, and third transmission paths, a transmission path to be used by a mobile communication terminal. | 12-12-2013 |
20140334386 | COMMUNICATION SYSTEM, GATEWAY APPARATUS, AND COMMUNICATION METHOD - A first gateway apparatus includes: an apparatus determining unit configured to receive a connection request signal for requesting a connection from the second communication apparatus and identify at least one of the group and service based on the connection request signal; and a data transfer unit configured to transfer data received from the second communication apparatus to the second gateway apparatus. | 11-13-2014 |
20150050954 | TERMINAL DEVICE, MOBILE MANAGEMENT DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD - An operation requesting unit of a terminal device configured to, in a case that the terminal device is unable to be connected to a gateway device configured to connect a public wireless communication network and a short-range wireless communication network, transmit to the mobile management device, a gateway operation request signal that requests operation while regarding the terminal device as a gateway device. | 02-19-2015 |
20150111574 | RELAY DEVICE, WIRELESS TERMINAL DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD - A communication system includes a wireless terminal device related to a predetermined service or group, a relay device, a base station device to be connected to the relay device, a gateway device, and a mobile management device. In the relay device included in the communication system, a registration processing unit transmits to the mobile management device, a first registration request signal that requests registration of the relay device, and receives first communication path information indicating a communication path between the relay device and the gateway device. A device determination unit receives from the wireless terminal device, a connection request signal that requests connection, and determines based on the connection request signal whether or not to transfer data related to the wireless terminal device. A data transfer unit transfers the data using the communication path indicated by the first communication path information. | 04-23-2015 |
20150195756 | MOBILE STATION DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, AND RECORDING MEDIUM - A mobile station device includes a peripheral regulated state acquirer configured to acquire regulated states of peripheral cells, a cell search processor configured to perform a cell search on peripheral cells selected based on the acquired regulated states, and a cell selector configured to select a handover destination cell based on a result of the cell search, thus making it possible to suppress a load on a base station of a process to avoid congestion. | 07-09-2015 |
