Abstract: A narrow-bandwidth terminal device performs radio communication at a bandwidth narrower than a system bandwidth. The narrow-bandwidth terminal device in an idle state camps on a cell, and performs discontinuous reception of a signal transmitted from the cell. The terminal device also determines a reception condition of the signal, for example, whether the signal can be received. When it is determined that the signal cannot be received, the narrow-bandwidth terminal device moves out of a coverage area of the cell while continuing to perform the discontinuous reception. When it is determined that a discontinuous reception timer has been completed, the narrow-bandwidth terminal device continues to perform the discontinuous reception.

Abstract: The radiation detector according to the present invention is always able to calculate the summation value accurately, regardless of the intensity of the fluorescent emission that is produced in the scintillator. That is, if the method for calculating the summation value set forth in the present invention is used, then the number of instantaneous intensity data d that are added together each time a fluorescent emission is produced in the scintillator will be larger the greater the intensity of the fluorescent emission. Doing this prevents the intensity of an intense fluorescent emission from being understated. Moreover, the summing portion in the present invention is able to calculate the summation value with high reliability. This is because the instantaneous intensity data used in calculating the summation value are above a threshold value a, causing the signal-to-noise ratios to be adequately high and the reliability to be high as well.

Abstract: Provided is a radiation detector that is capable of accurately calculating the time of occurrence of fluorescence. In addition to a configuration that calculates a single signal time, the present invention, in view of the case in which a multiple event occurs, also has a configuration that on the basis of an added signal generated by adding detection signals together, calculates the time of occurrence of fluorescence (added signal time). The radiation detector according to the present invention is configured to output the added signal time as the time of occurrence of fluorescence when the number of detection elements 3a in the fluorescence detection is plural (at the time of a multiple event). In the case of a multiple event, from the viewpoint of strengthening of a signal addition, an added signal time is more accurate than a single signal time.

Abstract: A closed subscriber group (CSG) cell is a cell that allows use of subscribers. In order to receive the service by the CSG cell, a CSG-ID is required to be notified to a user equipment, which cannot be obtained in a situation outside the reach of radio waves from a non-CSG cell. In a mobile communication system including base stations respectively provided to a CSG cell and a non-CSG cell in which access is made to the CSG cell with the use of a CSG-ID issued in a case where use of the CSG cell is allowed, the base station provided in the CSG cell refers to the notified identification information of a user equipment and then transmits a tracking area update request from the user equipment to a core network, and the core network determines whether the user equipment is allowed to use the CSG cell and, in the case where the use is allowed, transmits a signal for allowing assignment of radio resources to the user equipment and the CSG-ID. The user equipment accesses the CSG cell with the use of the CSG-ID.
