The base station includes a first assigning unit and a second assigning unit. The first assigning unit, in execution of first communication using a single cell of the base station with the terminal, assigns, to the terminal, a first identification number as an identification number associated uniquely with the single cell from a predetermined number of identification numbers for identifying terminals. The second assigning unit, in execution of second communication simultaneously using a plurality of cells with the terminal, assigns, to the terminal, a second identification number as an identification number associated commonly with the plurality of the cells from the predetermined number of the identification numbers excluding the first identification number. The terminal includes a communication control unit. The communication control unit performs the first communication or the second communication by using the first identification number or the second identification number assigned by the base station. |

1. A communication system comprising:
a base station; and a terminal, wherein the base station includes a first processor that performs a first process including:
first assigning, in execution of first communication using a single cell of the base station with the terminal, to the terminal, a first Cell-Radio Network Temporary Identifier (C-RNTI) number as a C-RNTI number associated uniquely with the single cell from a predetermined number of C-RNTI numbers for identifying the terminal; andsecond assigning, in execution of second communication simultaneously using a plurality of cells with the terminal, to the terminal, a second C-RNTI number as a C-RNTI number associated commonly with the plurality of the cells from the predetermined number of the C-RNTI numbers excluding the first C-RNTI number, and the terminal includes a second processor that performs a second process including performing the first communication by using the first C-RNTI number assigned by the base station, or performing the second communication by using the second C-RNTI number assigned by the base station, wherein the predetermined number of the C-RNTI numbers are divided, in advance, into a first C-RNTI number group containing C-RNTI numbers including the first C-RNTI number and a second C-RNTI number group containing C-RNTI numbers including the second C-RNTI number, the base station further includes:
a first storage that stores therein the first C-RNTI number group; anda second storage that stores therein the second C-RNTI number group, the first assigning includes assigning, in execution of the first communication, the first C-RNTI number to the terminal from the first C-RNTI number group stored in the first storage unit, and the second assigning includes assigning, in execution of the second communication, the second C-RNTI number to the terminal from the second C-RNTI number group stored in the second storage unit. |
