The present disclosure relates to a method and an apparatus for reducing power consumption of a terminal device. In some embodiments, the apparatus includes processing circuitry and interface circuitry. In various embodiments, the terminal device receives wireless communication service from a network. The processing circuitry releases wireless network connection of the terminal device from the network in response to an instruction for reducing the power consumption of the terminal device. The processing circuitry further adjusts a subset of communication parameters from first settings to second settings to reduce the power consumption of the terminal device. The communication parameters are associated with a baseband processing device in the terminal device. The processing circuitry also reestablishes the wireless network connection of the terminal device to the network. When the wireless network connection is being reestablished, the interface circuitry sends the adjusted communication parameters to an access device in the network.
