A purpose is to provide a control apparatus capable of advancing performing a paging process when packet arrival occurs while the control apparatus arranged in a core network holds two Temporary IDs regarding a communication terminal. A control apparatus (10) according to the present disclosure includes a communication means (12) for preforming a paging process using extended idle-mode Discontinuous Reception (DRX) (eDRX) and a calculation means (11) for determining a timing for paging using a first temporary identifier allocated to a communication terminal (30) and a second temporary identifier allocated to the communication terminal (30) and different from the first temporary identifier, in which the communication means (12) performs a paging process using the first temporary identifier corresponding to a first timing for initial paging.
