  • Patent number: 10588082
    Abstract: A wireless communication system that enables a wireless terminal to perform communication using a plurality of component carriers having different frequencies. The wireless communication system monitors a communication state of each of the component carriers allocated to the wireless terminal; distributes, to the component carriers, data to be transmitted, based on the communication state of each of the component carriers; starts a reception operation at a predetermined timing in a non-reception period of a second cycle during a discontinuous reception operation at the second cycle in some of the component carriers allocated to the wireless terminal, and performs the reception operation a predetermined number of times, the second cycle being longer than a first cycle.

  • Patent number: 10455371
    Abstract: A system of this invention is directed to a communication processing system that suppresses an increase in number of control messages even if devices cannot receive a group message. The communication processing system includes a holder that holds identifiers of a plurality of devices included in a device group as a target of a group messaging requested from an application, an unreached-device list acquirer that acquires an unreached-device list created by excluding, identifiers of devices which the group message has reached from the identifiers held in the holder based on responses to delivery of the group message, and a message deliverer that delivers a message based on the group messaging to devices having identifiers included in the unreached-device list.

  • Publication number: 20170097762
    Abstract: An apparatus according to this invention is an information processing apparatus for implementing more user-friendly screen control. The information processing apparatus has as its feature to acquire a stroke of a user operation on a touch panel, and lock a scroll operation by the stroke, if the operation by the stroke is estimated to draw a contour of a closed region. Furthermore, the information processing apparatus has as its feature to release the lock of the scroll operation if the operation by the stroke is not estimated to draw the contour of the closed region. The estimation processing is performed based on the moving amount of the stroke.
