    摘要: It is to mitigate a deterioration of an interference reduction performance between multi-feeder links due to a weight-calculation processing delay, when a combination of plural antennas for feeder link (FL antenna) incorporated in an aerial-staying type communication relay apparatus and plural gateway (GW) stations changes. With respect to each of plural combination patterns in which combinations of plural FL antennas of relay communication station and the plural GW stations are different from each other, a system calculates and stores a weight corresponding to each of the plural GW stations, selects a calculation result of the weight of the combination pattern corresponding to the changed combination, when the combination of the plural FL antennas and the plural GW stations changes due to at least one of a rotation and movement of the communication relay apparatus, and suppresses an interference between the feeder links when transmitting and receiving signals between the relay communication station and the plural GW stations based on the selected calculation result of the weight of the combination pattern.

    摘要: Provided is a communication system including: a controller; and an SR gateway which converts an SRv6-compliant packet received from an IP network into a GTP-U-compliant packet. The SR gateway includes a notification unit which notifies the controller, and a router connected to an IP network, of a route including an IP prefix including an address of a reachable gNB in NLRI and an SID of the SR gateway in a BGP attribute, and the controller includes a storage unit which stores an IP prefix including the address of the gNB, and a SID of the SR gateway, in association with each other, and an advertisement unit which searches the storage unit by using, as a key, an address of a gNB included in a UE session information in SMF notified when UE is attached, and when a match is found, advertises route information of the UE to the router.

    摘要: It is provided of a system capable of estimating a current position of a terminal apparatus, even if a terminal apparatus for mobile communication is in a condition of non-receiving or inability to receive GNSS signals. A radio relay apparatus, in which a relay station mounted on a drone, transmits radio waves from a directional antenna toward the ground while flying in an upper airspace above a target area on the ground, and transmits position information on its own apparatus obtained based on the GNSS signal, to an information processing apparatus. The terminal apparatus measures a reception power or a reception quality of radio waves transmitted from the radio relay apparatus, and transmits reception measurement information regarding the measurement result of the reception power or the reception quality, to the information processing apparatus. The information processing apparatus estimates the position of the terminal apparatus in the target area, based on the position information from the radio relay apparatus received in a flight time period during which the radio relay apparatus flies in the upper airspace above the target area and the reception measurement information from the terminal apparatus. The information processing apparatus may estimate the position where the reception power or the reception quality from the terminal apparatus is maximum, as the position of the terminal apparatus.
