<p>A base station includes a determination unit configured to determine a restriction rate for each of plural kinds of restrictions; a timing determination unit configured to, by using a timing at which a user device in idle mode wakes up in every discontinuous reception cycle, group the user device into any one of a total number M G of groups and determine a timing for transmitting a paging signal for each of the groups; a restriction group determination unit configured to determine a restriction group number M R that is less than a sum of all restriction-rate-corresponding group numbers where one of the restriction-rate-corresponding group numbers corresponds to the restriction rate of one of the plural kinds of restrictions, to determine the restriction group number M R of groups as one or more restriction-target groups, and to change at least one group corresponding to the one or more restriction-target groups in each of predefined periods; and a transmission unit configured to transmit the paging signal to the user device that belongs to at least one of the one or more restriction-target groups, and to transmit system information indicating that the plural kinds of restrictions are applied.</p> |
