| 20130023227 | COMMUNICATION APPARATUS AND COMMUNICATION METHOD - A communication apparatus includes a receiving unit, an extracting unit, a generating unit and a transmitting unit. The receiving unit receives a signal from a first network using a first communication method. The extracting unit extracts, from a signal received via a control channel of the first network, notification information that is broadcast to be notified to a communication apparatus belonging to the first network and also used by a communication apparatus belonging to a second network. Here, the second network uses a second communication method different from the first communication method. The generating unit generates a notification frame used to notify the communication apparatus belonging to the second network of the notification information. The transmitting unit transmits the notification frame to the communication apparatus belonging to the second network. | 01-24-2013 |

| 20130065626 | WIRELESS COMMUNICATION SYSTEM, MANAGEMENT DEVICE, AND MOBILE TERMINAL UNIT - A management device includes a managing unit that manages whether a dedicated access slot different from an access slot is assigned to the mobile terminal unit, the access slot being arbitrarily used by a mobile terminal unit when the mobile terminal unit gets random access to a base station unit, a selecting unit that selects a dedicated access slot which has not been assigned among dedicated access slots managed by the managing unit when having received a priority notification indicating that a mobile terminal unit being a communicating destination of the base station unit is a priority terminal given priority for performing communication, and an instructing unit that instructs the base station unit managed by the management device to reserve the dedicated access slot selected by the selecting unit. | 03-14-2013 |
| 20130244643 | COMMUNICATION SYSTEM, METHOD OF DETECTING HOLE AREA, BASE STATION APPARATUS, AND MOBILE STATION APPARATUS - A method of detecting a hole area to be generated in a cover area of a communication system which includes a plurality of base station apparatuses and mobile station apparatuses, includes: measuring received powers from the plurality of base station apparatuses at the mobile station apparatuses, and, based on the received power from the other base station apparatus among a plurality of base station apparatuses other than the base station apparatus which covers a cell in which the mobile station apparatuses are positioned, detecting a hole area to be generated when a signal output from the base station apparatus is stopped. | 09-19-2013 |
| 20130308514 | COMMUNICATION SYSTEM, COMMUNICATION METHOD, MOBILE TERMINAL, DEVICE, AND BASE STATION - A communication system includes a base station and a mobile terminal device. The base station includes a detection information notifying unit. The detection information notifying unit notifies, using a predetermined control channel, the mobile terminal device of detection information that includes a power-saving time that indicates a time that elapses before the base station enters a power-saving state. The mobile terminal device includes a detecting unit and a region information notifying unit. The detecting unit, when being notified of the detection information by the detection information notifying unit, detects a region in which a mobile terminal device is not capable of communicating with any base station based on the power-saving time included in the detection information. The region information notifying unit notifies a given base station of information on the region detected by the detecting unit. | 11-21-2013 |
