And after receiving the paging message, the user equipment in the idle state reads the identification of the paged equipment in the paging record list. If the user equipment determines that the identifier of the user equipment is consistent with the identifier of the paged equipment, initiating an uplink access to perform a Radio Resource Control (RRC) connection establishment process so as to receive a call, and if the user equipment does not find the identifier of the user equipment consistent with the identifier of the paged equipment, discarding the received paging message by the user equipment.

The user equipment judges whether the signal-to-noise ratio of the first SSB is greater than a preset threshold value or not, if the signal-to-noise ratio of the first SSB is greater than the preset threshold value, the PBCH in the first SSB is decoded to obtain a decoding result, if the decoding result of the PBCH is correct, the user equipment performs frequency offset and time offset compensation, determines a corresponding PMO according to the first SSB after the frequency offset and time offset compensation, and receives a paging message on the PMO corresponding to the first SSB.

The preset threshold is set by default by the user equipment, configured by a protocol, or configured by the network side equipment, which is not limited in this embodiment.

The user equipment stores a one-to-one correspondence relationship between each SSB and the PMO.

That is, for each paging cycle after the ue switches from the connected state to the idle state, the target paging listening policy of the next paging cycle is determined after the paging occasion of the paging cycle.

Optionally, the target PMO of the paging cycle is configured to indicate time-frequency domain location information of Downlink Control Information (DCI), the DCI is configured to indicate time-frequency domain location information of a Physical Downlink Shared Channel (PDSCH), and the ue determines a target paging monitoring policy of a next paging cycle after a paging occasion of the paging cycle, where the target paging monitoring policy includes: and the user equipment determines a target paging monitoring strategy corresponding to the next paging cycle according to the DCI decoding result and/or the PDSCH decoding result of the paging cycle.

And if the decoding result of the DCI is correct, decoding the time-frequency domain position information of the PDSCH indicated by the DCI to obtain the decoding result of the PDSCH. If the decoding result of the PDSCH is correct, determining a target paging monitoring strategy corresponding to the next paging cycle as a first paging monitoring strategy; and if the decoding result of the PDSCH is wrong, determining that the target paging monitoring strategy corresponding to the next paging cycle is the second paging monitoring strategy.

Namely, the user equipment determines a target paging monitoring strategy corresponding to the next paging cycle according to the decoding result of the DCI and/or the decoding result of the PDSCH of the paging cycle, and the method includes the following three possible implementation manners:

in a possible implementation manner, the paging result is sent when the decoding result of the DCI of the paging cycle is correct and the decoding result of the PDSCH is correct, and the paging result is used for indicating the decoding result of the PDSCH. And after receiving a feedback message of the paging result, determining that a target paging monitoring strategy corresponding to the next paging cycle is a first paging monitoring strategy, wherein the feedback message is used for indicating whether the paging message pages the user equipment.

When the DCI decoding result of the paging cycle is correct and the PDSCH decoding result is correct, the UE sends the paging result to the high layer, the UE receives the feedback message sent by the high layer, and if the feedback message is used for indicating that the paging message is used for paging the UE, the UE responds to the paging message and enters a connected state; if the feedback message is used for indicating that the paging message is not paging the user equipment, the user equipment discards the paging message. After the ue receives the feedback message, it determines that the target paging listening policy corresponding to the next paging cycle is the first paging listening policy, and then step 304 is performed.

In another possible implementation manner, when the decoding result of the DCI in the paging cycle is incorrect, the target paging listening policy corresponding to the next paging cycle is determined to be the first paging listening policy.

When the decoding result of the DCI of the paging cycle is incorrect, the ue determines that there is no paging message, determines that the target paging listening policy corresponding to the next paging cycle is the first paging listening policy, and performs step 304.

In another possible implementation manner, when the decoding result of the DCI of the paging cycle is correct and the decoding result of the PDSCH is incorrect, the target paging listening policy corresponding to the next paging cycle is determined to be the second paging listening policy.
