  • Patent number: 10736122
    Abstract: The present invention is to enable setting of an appropriate subordinate cell or subordinate base station according to quality of a wireless communication service applied to a terminal or a type of a terminal. The terminal (3) is connected to a wireless communication network via a base station (1A), and when the base station (1A) sets another base station (1B or 1C) as the subordinate cell or the subordinate base station, the base station (1A) selects the subordinate cell or the subordinate base station from among either (a) candidates according to QoS (Quality of Service) applied to the terminal or (b) candidates according to the type of the terminal.

  • Patent number: 10293056
    Abstract: The present invention relates to non-viral gene therapy methods and compositions for treatment of hyperproliferative disease in humans. More specifically, the invention is directed, in one embodiment, to lipid formulations which form stable liposome structures, capable of efficient in vivo nucleic acid transfer. In other embodiments, methods and compositions are directed to liposome transfer of anti-proliferative nucleic acids, wherein the transfer of the nucleic acids is cell specific via cell specific targeting moieties. The present invention, thus provides non-viral, liposome compositions and methods of gene transfer particularly useful for targeting and treating hyperproliferative disease.

  • Patent number: 10021537
    Abstract: [Problem] To provide a wireless communication network system and a method for determining a representative sensor device for appropriately selecting, from a plurality of sensor devices, a device with which a server communicates. [Solution] A server (120) transmits a group representative determination request including a list of parameters for determining a representative sensor device. Sensor devices (140a-z) transmit, upon receiving the parameter list, a device parameter indicating the parameter of each of the sensor devices corresponding to the parameter list. The representative sensor device is determined on the basis of the device parameters transmitted by the sensor devices (140a-z). The representative sensor device transmits, to the server (120), measurement result information generated by the sensor device itself and measurement result information generated by the other sensor devices.

  • Patent number: 9749890
    Abstract: A mobile terminal measures surrounding cell information on the basis of a direction from a base station and selects only cell information on an unknown cell detected from the surrounding cell information and notifies the base station of the cell information on the unknown cell when information on surrounding cells is acquired by the base station. A wireless communication system includes the base station and the mobile terminal The base station includes a cell information acquisition unit for acquiring cell information including cell quality information and cell identification information on surrounding cells located around the base station, and a transmission unit for transmitting, to the mobile terminal, known cell information and acquisition direction for cell information on unknown cells that do not have cell information corresponding to the known cell information.

  • Patent number: 9398504
    Abstract: A mobile communication system (9) of the invention is provided with a first wireless base station (91) managing a macro cell, a second wireless base station (92) managing a small cell included in the macro cell, and a service establishment control unit (93) executing a service establishment control of establishing a service between a mobile terminal and the first wireless base station (91) in the macro cell in response to a request of establishing a service from the mobile terminal. When the service whose establishment is requested from the mobile terminal is a specific service, the service establishment control unit (93) executes a handover control of the mobile terminal from the first wireless base station (91) to the second wireless base station (92), and then, executes a service establishment control of establishing a service between the mobile terminal and the second wireless base station (92) in the small cell.
