  • Patent number: 11625868
    Abstract: A centerline for generating network data of an indoor space can be generated while limiting the amount of calculation. Points where first straight lines and second straight lines constituting centerlines meet are created using re-entrant vertices (Step 1). The points created in Step 1 are connected by lines (Step 2). Connection lines corresponding to the longest sides are repeatedly deleted from closed polygons defined by the connection lines obtained in Step 2 until no closed polygons are left (Step 3). Each vertex of the connection lines obtained in Step 3 is connected to a farthest center point on the perimeter of the shape of the passage if there is such a farthest center point to which the vertex can be connected without touching the perimeter and without crossing other connection lines (Step 4).

  • Publication number: 20230091559
    Abstract: In a communication system, an eNB and a UE transmit and receive a UE monitoring message for confirming the state of the UE in a predetermined UE monitoring period. For example, in UE monitoring periods, a UE monitoring procedure is performed, so that the UE transmits the UE monitoring message to the eNB. Upon receipt of the UE monitoring message, the eNB transmits delivery confirmation information to the UE. The UE monitoring period is set as, for example, a period shorter than a TAU period. This allows the UE monitoring process to confirm the state of the UE even if the TAU period is lengthened. The eNB may transmit the UE monitoring message to the UE.

  • Patent number: 11569968
    Abstract: The present invention has an object to provide a communication system capable of minimizing effects due to a delay among a plurality of base station devices as much as possible in scheduling for communication with a terminal device in cooperation among the plurality of base station devices. Cells1 to 3 can each perform scheduling without using information for scheduling notified from one or a plurality of cells among pieces of information for scheduling notified from other cells. For example, in a case where an interface between the cell1 and cell3 has a large delay amount, the cell1 performs scheduling without using information S13 notified to the cell1 by the cell3, and the cell3 performs scheduling without using information S11 notified to the cell3 by the cell1.

  • Publication number: 20220361166
    Abstract: A mobile communication system capable of reducing energy consumption of a network node in a local area range. When judging that there is a shift trigger, a local eNB shifts from a normal operation to an energy saving operation. In the energy saving operation, the local eNB stops the operation of transmitting at least a part of downlink transmission signals to be transmitted to a user equipment (UE) and performs the operation of receiving an uplink transmission signal transmitted from the UE. When judging that it has received the uplink transmission signal (RACH) in the energy saving operation, the local eNB shifts to the normal operation.
