a first duration parameter configured to indicate information on a service duration during which the cell can provide a service, or a first time point parameter configured to indicate information on a time point when the cell stops providing the service.

3 . The method of claim 1 , further comprising:

determining a respective parameter value of a first duration parameter included in the system information for each sending period of the system information, based on a maximum service duration during which the cell can provide the service and a respective period duration of each sending period of the system information.

4 . The method of claim 1 , wherein sending the target time parameter comprises:

sending a Radio Resource Control (RRC) message comprising the target time parameter to the terminal.

5 . The method of claim 4 , wherein sending the RRC message comprising the target time parameter to the terminal comprises:

sending a RRC release message comprising the target time parameter to the terminal, in response to determining that the terminal switches from a connected state to an idle state or an inactive state.

6 . The method of claim 5 , further comprising:

determining, in response to the target time parameter comprising a first duration parameter configured to indicate information on a service duration during which the cell can provide the service, a parameter value of the first duration parameter comprised in the RRC release message based on a maximum service duration during which the cell can provide a service and a service duration during which the cell has provided the service.

7 . The method of claim 1 , wherein the target time parameter further comprises a second time parameter configured to indicate information on a service time of a neighbor cell,

wherein the second time parameter comprises at least one of:

a second duration parameter configured to indicate information on a service duration during which the neighbor cell is going to provide a service to the terminal, a second time point parameter configured to indicate information on a start time point when the neighbor cell starts providing the service, or a third time point parameter configured to indicate information on a time point when the neighbor cell stops providing the service.

8 . A cell reselection method, performed by a terminal, comprising:

receiving a target time parameter, wherein the target time parameter comprises a first time parameter configured to indicate information on a service time of a cell; and

performing a cell reselection based on the target time parameter;

wherein receiving the target time parameter comprises receiving system information containing the target time parameter; and

wherein updating a parameter value of a first duration parameter included in the system information does not trigger a notification for an update of the system information.

9 . The method of claim 8 , wherein the first time parameter comprises at least one of:

a first duration parameter configured to indicate information on a service duration during which the cell can provide a service, or a first time point parameter configured to indicate information on a time point when the cell stops providing the service.

10 . The method of claim 9 , wherein performing the cell reselection based on the target time parameter comprises:

configuring a timing duration of a cell reselection timer based on the first duration parameter, in response to the target time parameter comprising the first duration parameter; and

performing the cell reselection in response to the cell reselection timer expiring.

11 . The method of claim 10 , wherein configuring the timing duration of the cell reselection timer based on the first duration parameter comprises one of:

configuring the timing duration of the cell reselection timer based on a parameter value of the first duration parameter comprised in received system information;

configuring the timing duration of the cell reselection timer based on a parameter value of the first duration parameter comprised in a received Radio Resource Control (RRC) release message; or

configuring the timing duration of the cell reselection timer based on the parameter value of the first duration parameter comprised in the RRC release message, in response to receiving the system information comprising the first duration parameter and the RRC release message comprising the first duration parameter.

12 . The method of claim 10 , further comprising one of:

triggering to start the cell reselection timer, in response to entering the cell through the cell reselection and receiving system information comprising the first duration parameter;

triggering to start the cell reselection timer, in response to switching from a connected state to an idle state or an inactive state and receiving a RRC release message comprising the first duration parameter; or

triggering to start the cell reselection timer in response to switching from the connected state to the idle state or the inactive state, a received RRC release message not comprising the first duration parameter, and received system information comprising the first duration parameter.

13 . The method of claim 10 , wherein after the cell reselection timer is started, the timing duration of the cell reselection timer remains unchanged.

14 . The method of claim 9 , wherein performing the cell reselection based on the target time parameter comprises:

performing the cell reselection before a time point indicated by the first time point parameter or when the time point indicated by the first time point parameter is reached, in response to the target time parameter comprising the first time point parameter.

15 . The method of claim 8 , wherein the target time parameter further comprises a second time parameter configured to indicate information on a service time of a neighbor cell,

wherein the second time parameter comprises at least one of:

a second duration parameter configured to indicate information of a service duration during which the neighbor cell is going to provide a service to the terminal, a second time point parameter configured to indicate information on a start time point when the neighbor cell starts providing the service, or a third time point parameter configured to indicate information on a time point when the neighbor cell stops providing the service.

16 . The method of claim 15 , further comprising:

determining, based on the second duration parameter, a target neighbor cell to be switched to in performing the cell reselection, in response to the target time parameter comprising the second duration parameter; or

determining, based on at least one of the second time point parameter or the third time point parameter, a target neighbor cell to be switched to in performing the cell reselection, in response to the target time parameter comprising at least one of the second time point parameter or the third time point parameter.

17 . A terminal, comprising:

a processor; and

a memory configured to store instructions executable by the processor; wherein the processor is configured to perform the cell reselection method of claim 8 .

18 . A base station, comprising:

a processor; and

a memory configured to store instructions executable by the processor;

wherein the processor is configured to:

configure, for a terminal, a target time parameter for performing a cell reselection, wherein the target time parameter comprises a first time parameter configured to indicate information on a service time of a cell; and

send the target time parameter,

wherein the processor is further configured to broadcast system information containing the target time parameter; and

wherein updating a parameter value of a first duration parameter included in the system information does not trigger a notification for an update of the system information.
