  • Patent number: 9750032
    Abstract: A P cell communication unit and an S cell communication unit establish communication with a mobile station using a plurality of radio resources of a first cell and a second cell overlapping the first cell. A moving speed measuring unit measures a moving speed of the mobile station based on a signal transmitted from the mobile station using the radio resources of the first cell. A scheduling processing unit stops an allocation of the radio resources of the second cell to the mobile station based on a wireless environment with the mobile station. The scheduling processing unit starts an allocation of the radio resources of the second cell to the mobile station when the moving speed of the mobile station is less than a certain value in a state in which the allocation of the radio resources of the second cell is stopped.

  • Patent number: 9526128
    Abstract: A REC unit manages card information on each of L1 cards handling a physical channel, L2-1 cards handling a logical channel, and L2-2 cards in which a scheduling function for communication processing performed with respect to the L1 card and/or the L2-1 card is implemented. A call control card of the REC unit selects, for each of first to third channels, a processing card establishing a signal path relevant to the logical channel from among the L1 card, the L2-1 card, and the L2-2 card. The call control card transmits connection relation information indicating a combination of the processing cards selected to each processing card. On the basis of the connection relation information received from the call control card, each processing card establishes the signal path for each of the first to third channels relevant to the logical channel between the processing cards.
