Abstract: An object is to provide a communication system that can determine an update timing of accumulated data even when a device apparatus cannot determine the update timing. The communication system according to the present invention includes a common service control apparatus (30) and application servers (50) to (52). When a collection request message for requesting collection of data is transmitted from an application server (50) included in the application servers (50) to (52) to the common service control apparatus (30), the common service control apparatus (30) evaluates as to whether to transmit data collected before the collection request message is transmitted from the application server (50) or to transmit newly collected data to the application server (50).
Abstract translation: 目的在于提供即使在设备装置不能确定更新定时的情况下也能够确定累积数据的更新定时的通信系统。 根据本发明的通信系统包括公共业务控制装置（30）和应用服务器（50）至（52）。 当从包含在应用服务器（50）至（52）中的应用服务器（50）向公共业务控制设备（30）发送用于请求数据收集的收集请求消息时，公共业务控制设备（30）评估 关于在从应用服务器（50）发送收集请求消息之前是否发送收集的数据，或者将新收集的数据发送到应用服务器（50）。

Abstract: A service control apparatus (20) according to the present disclosure includes: a communication unit (21) configured to receive a first communication pattern that defines a timing of communication between a service providing apparatus (30) and a communication terminal (10) from the service providing apparatus (30) and a second communication pattern that defines a timing of communication between a service providing apparatus (32) and the communication terminal (10) from the service providing apparatus (32); and a controller (22) configured to determine whether the first communication pattern and the second communication pattern indicate communication timings different from each other. When the first communication pattern and the second communication pattern indicate communication timings different from each other, the communication unit (21) transmits a message to the second service providing apparatus (32) requesting it to change its communication pattern to the first communication pattern.

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.

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.
