Abstract: A discontinuous reception apparatus for a terminal, where discontinuous reception includes a sleep period and an active period that are of the terminal and that are indicated by a network. The apparatus includes: a receiving circuit configured to receive motion state information of the terminal, where the motion state information is used to indicate a motion state of the terminal; and a first processing circuit configured to determine, based on the motion state of the terminal, duration for waking up the terminal in advance, and enable the terminal to enter the active period in advance by the duration before the sleep period indicated by the network ends. The apparatus is configured to enter, based on a change in the motion state of the terminal or a change in received signal quality, the active period in advance before the sleep period indicated by the network ends
