Abstract: An interference detection system includes a plurality of radio frame acquisition apparatuses and an interference detection apparatus. The interference detection apparatus includes radio frame information reception part, radio frame information storage part, simultaneous frame extraction part, and interference detection part. A radio frame information reception part receives the radio frame information transmitted from the radio frame acquisition apparatus. A radio frame information storage part stores the received radio frame information. A simultaneous frame extraction part extracts first radio frame, and second radio frame demodulated simultaneously or almost simultaneously with first radio frame. An interference detection part determines whether or not first radio frame and second radio frame are interfering with each other on the basis of whether or not there exists(exist) radio frame acquisition apparatus(es) which has(have) demodulated first radio frame and second radio frame simultaneously or almost simultaneously, among a plurality of the radio frame acquisition apparatuses.

Abstract: In order to enable prediction of communication having high quality requirements, this communication device is provided with: a determination unit that determines that a change has occurred in the communication state of communication which is performed, with a device connected to a network, by each of a first terminal and a second terminal communicating with the device; and a derivation unit that, when the change in the second terminal is determined to be being occurring in synchronization with the change in the first terminal, derives a second change time at which the change occurs in the second terminal, on the basis of a first change time at which the change occurs in the first terminal.

Abstract: In order to reduce wasteful delays occurring when a mobile terminal whose RRC state is a state wherein communication is possible transfers in a temporarily stopped state, a distribution sequence determination device, which determines the distribution sequence for push messages transmitted to each of multiple terminals, determines the distribution sequence on the basis of whether each of the multiple terminals is in a state wherein communication is possible or is in a temporarily stopped state, so as to transmit the push messages to each of the multiple terminals in a distribution sequence in which terminals in a state wherein communication is possible are given priority over terminals in the temporarily stopped state.
