  • COMMUNICATION SYSTEM AND CONCENTRATOR
    Publication number: 20190075472
    Abstract: A communication system of the present invention includes a user equipment (UE), and a plurality of cells that perform communication with the UE. The plurality of cells include a macro cell having a relatively-wide-range coverage, and a plurality of small cells having a relatively-narrow-range coverage. The plurality of small cells are connected to a concentrator. The concentrator selects the small cell to which the UE is to be connected, from among a plurality of small cells, based on the flow of at least either one of the received data that each small cell receives from the UE and the transmission data that each small cell transmits to an MME and an S-GW.
