  • Patent number: 10616854
    Abstract: An SGW-C acquires correlation information in advance and retrieves an SGW-U corresponding to a tracking area of a movement destination of UE with reference to the correlation information. An MME issues a request for connection between the SGW-U retrieved by the SGW-C and an eNB. In this way, since the correlation information in which SGW-Us and tracking areas are correlated with each other is stored, it is possible to appropriately change a tracking area even in a situation in which a control plane and a user plane are separated.

  • Publication number: 20200029273
    Abstract: In a communication system (1), when there is no access destination corresponding to a service type to be used by a piece of UE (50) in one of cellular communication and non-cellular communication, a retrieval unit (13) of a DB server (10) selects an access destination by referring to correspondence information in the other of the cellular communication and the non-cellular communication. Thus, when there is no access destination corresponding to the service type to be used by the UE (50) in one of the cellular communication and the non-cellular communication, the access destination corresponding to the service type is selected in the other of the cellular communication and the non-cellular communication. Therefore, it is possible to select an access destination suitable for the service type from both the cellular communication and the non-cellular communication.

  • Publication number: 20190359032
    Abstract: A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

  • Patent number: 10473774
    Abstract: A radar device includes a transmission part that transmits a radar wave which has been frequency-modulated such that one measurement cycle has a rising section in which a frequency increases and a falling section in which a frequency decreases, a reception part that derives respective beat signals of the rising section and the falling section, and a signal processor that performs a precipitation determining process on the basis of an analysis of the beat signals. In the precipitation determining process, in the absence of objects other than precipitation objects from a transmission range of the radar wave, it is determined whether a spectral similarity of the frequency spectra of the rising and falling section with precipitation reference spectra is not less than a threshold, and if the spectral similarity is not less than the threshold as a result of the determination, it is determined that precipitation is present.
