In order to better understand the technical solution described in any embodiment of the present disclosure, first, an application scenario in the related art is described:

in one embodiment, for the radio resource control (RRC, radio Resource Control) connection state, a power saving signal, i.e. a Wake Up Signal (WUS) or a power saving downlink control information (DCP, DCI for powersave), is introduced. The WUS signal is a low-power consumption detection signal. If the terminal detects WUS signal, it means that it needs to monitor the physical downlink control channel (PDCCH, physical downlink control channel), but if WUS is not detected, it skips the monitoring of PDCCH.

In one embodiment, for the RRC idle state, a power saving signal (e.g., PEI) is generally configured before a Paging Occasion (PO), if the terminal does not detect the power saving signal, the Paging DCI needs to be skipped, otherwise, the Paging DCI needs to be monitored.

In one embodiment, a PDCCH skip (skip) mechanism is introduced for the RRC connected state, i.e., PDCCH skip will be carried in DCI to inform the terminal to skip listening for a period of time or to switch the search space group.

In this case, the modem (modem) of the terminal is required to detect the power saving signal.

In one embodiment, a separate transceiver (low power wake-up receiver) is introduced to receive the power save signal, and either the modem portion or the main radio (main radio) portion of the terminal can wake up only after the separate transceiver has been awakened, otherwise the portion of the modem will remain in a power-save state; the energy saving state may be a sleep state, a power saving state, or a shutdown state, where the shutdown state may be a state in which a part of functions or all functions are turned off.

In one embodiment, for a terminal in an RRC idle state, if the terminal Identity ue-Identity contained in the paging record PagingRecord matches the ue-Identity allocated by the upper layer, the ue-Identity and the access type accessType are forwarded to the upper layer.

In one embodiment, for a terminal in an RRC inactive state, if ue-Identity contained in the PagingRecord matches a deactivated state radio network temporary Identity (I-RNTI, I-RadioNetwork Temporary Identifier) stored by the terminal, initiating a resume request; if the ue-Identity contained in the PagingRecord matches the upper layer allocated ue-Identity, the ue-Identity and the accessType (if present) are forwarded to the upper layer, and upon transitioning to the RRC idle state, a release operation is performed, the release source being "other".
