Step S10, judging whether the terminal is in an idle state;

The state of the terminal includes an idle state and a connected state. When the terminal enters the idle state, cell reselection is required. Therefore, reducing the number of times the terminal performs cell reselection can reduce the power consumption of the terminal in the idle state.

Step S20, if it is judged that the terminal is in an idle state, then detecting the standby state of the terminal;

The standby state of the terminal includes strong power state, medium power state and weak power state. The corresponding reselection flag can be set for the terminal standby state. For example, the reselection flag of the strong power state is NORMAL PERIOD, and the reselection flag of the medium power state It is SHORT PERIOD, the reselection flag of the weak current state is SHORT PERIOD,

Set the reselection period according to the reselection flag.

Step S30, setting the reselection cycle of the terminal according to the standby state of the terminal;

The standby state of the terminal includes a strong power state, a medium power state, and a weak power state. Different reselection cycles are set according to the different power state. After judging that the standby state of the terminal is a strong power state, the terminal performs cell reselection-related measurements. , judging and triggering, in the medium power state and weak power state, the reselection period of the terminal can be extended, and the number of cell reselections performed by the terminal can be reduced. The reselection flag can be set for the three standby states of the terminal, and the reselection period of the terminal can be set according to the reselection flag.

Step S40, after the end of the reselection period, the terminal is controlled to perform cell reselection.

Since the reselection cycle is set differently for different standby states of the terminal, when the terminal is in the middle power state and the weak power state, extending the reselection cycle of the terminal can reduce the number of times the terminal performs cell reselection and reduce the power consumption of the terminal .

When the terminal is in an idle state, a period for the terminal to perform cell reselection is set according to the standby state of the terminal, and after the period ends, the cell reselection is performed. Each standby state corresponds to a different reselection cycle, which reduces the number of cell reselections performed by the terminal in the idle state, and saves energy consumption of the terminal.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of an embodiment of setting a reselection period of a terminal according to a power-on state of the terminal in the cell reselection method of the present invention.

If the terminal is not in a strong power state, it can be further judged whether the terminal is in a medium power state. Weak state. If the terminal is in a strong power state, you can set the reselection period of the terminal to zero, that is, after judging that the terminal is in a strong power state, the terminal will perform cell reselection-related measurements, judgments, and triggers, but when the terminal is in a strong power state, it will not Limited to setting the reselection period of the terminal to zero, a shorter period may also be set, and the terminal performs cell reselection after the period ends.

The corresponding reselection flag can be set for the standby state of the terminal. The reselection flag of the strong power state can be set as NORMAL PERIOD. When the reselection flag is NORMAL PERIOD, the reselection period of the terminal can be set to zero.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of another embodiment of setting the reselection period of the terminal according to the power-on state of the terminal in the cell reselection method of the present invention.

Based on the above-mentioned embodiment, after step S31, it also includes:

Step S33, if it is judged that the terminal is not in a strong power state, then judge whether the terminal is in a medium power state;

Step S34, if it is judged that the terminal is in the power-off state, then setting the reselection period of the terminal to be a short period.

If the terminal is not in the strong power state, it can be further judged whether the terminal is in the medium power state, and if the terminal is not in the medium power state, it can be further judged whether the terminal is in the weak power state. When it is judged that the terminal is in the power state, the reselection flag corresponding to the power state can be set to SHORT PERIOD. When the reselection flag is SHORT PERIOD, the reselection period of the terminal is set to a short period. After the short period ends , the terminal performs cell reselection. Since the power in the medium power state is weaker than that in the strong power state, the power consumption of the terminal can be reduced by prolonging the cell reselection cycle of the terminal.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of another embodiment of setting the reselection period of the terminal according to the power-on state of the terminal in the cell reselection method of the present invention.

Based on the above-mentioned embodiment, after step S33, it also includes:

Step S35, if it is judged that the terminal is not in the medium power state, it is judged whether the terminal is in the weak power state;

Step S36, if it is judged that the terminal is in a weak power state, then setting the reselection period of the terminal to be a long period.

If the standby state of the terminal is not in the medium power state, it may be further determined whether the standby state of the terminal is in the weak power state. When it is judged that the terminal is in a weak current state, the reselection flag corresponding to the weak current state can be set to LONG PERIOD. When the reselection flag is LONG PERIOD, the reselection period of the terminal is set to a long period. Perform cell reselection. Since the power in the weak power state is relatively weaker than that in the medium power state, the power consumption of the terminal can be reduced by prolonging the cell reselection cycle of the terminal.

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of detecting the power-on state of a terminal in the cell reselection method of the present invention.

Based on the foregoing embodiments, step S20 includes:

Step S21, setting the detection period of the standby state of the terminal;

In step S22, after the detection period ends, the power-on state of the terminal is detected.
