A method for reducing power consumption of a trunking terminal in a broadband trunking system, comprising: receiving, by the trunking terminal, a group call configuration instruction transmitted by a base station; configuring a group call context, a discontinuous reception, DRX, instruction and group call resources by the trunking terminal based on the group call configuration instruction; and executing the discontinuous reception instruction by the trunking terminal; sensing a physical channel by the trunking terminal when it is determined that an active phase of the discontinuous reception instruction is entered; and stopping sensing the physical channel by the trunking terminal when it is determined that a dormant phase of the discontinuous reception instruction is entered, wherein the trunking terminal is a group call terminal in a connected state, and the discontinuous reception instruction comprises a trunking group call discontinuous reception instruction and a single call discontinuous reception instruction, the sensing a physical channel by the trunking terminal when it is determined that an active phase of the trunking group call discontinuous reception instruction is entered comprises: sensing a group call channel by the trunking terminal when an active phase of the trunking group call discontinuous reception instruction is entered and an active phase of the single call discontinuous reception instruction is entered; and the stopping sensing the physical channel by the trunking terminal when it is determined that a dormant phase of the trunking group call discontinuous reception instruction is entered comprises: turning off a receiver by the trunking terminal to stop sensing the group call channel when it is determined that a dormant phase of the trunking group call discontinuous reception instruction is entered and a dormant phase of the single call discontinuous reception instruction is entered, wherein a hybrid automatic request, HARQ, round trip time, RTT, timer is provided in each downlink, DL, HARQ process, in a case that the HARQ RTT time expires and data received in the HARQ process fails to be decoded, the trunking terminal starts a DRX-RetransmissionTimer for the HARQ process, in a case that the DRX-RetransmissionTimer is running, the trunking terminal senses a physical downlink control channel, PDCCH, for HARQ retransmission, the base station calls the HARQ retransmission immediately after the HARQ RTT timer expires, radio resources are reserved for the HARQ retransmission by the base station, and the DRX-RetransmissionTimer is configured with a short time. receiving, by the trunking terminal, a group call configuration instruction transmitted by a base station;
