  • Publication number: 20200015168
    Abstract: This invention provides a communication processing system that reduces the power consumption of a remote UE associated with measurement of a strength of a received signal. The communication processing system includes a communication terminal, a base station, relay stations that relay communication between the communication terminal and the base station, a measurer that measures, in the communication terminal, a strength of a signal received from one of the relay stations, and a controller that controls to reselect another of the relay stations if the measured strength of the received signal is smaller than a first threshold, and reduce a count of measuring the strength of the received signal by the measurer if the measured strength of the received signal is larger than the second threshold which is larger than the first threshold.

  • 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.
