The rapid development of communication provides much convenience for our life, and the 5G network is faster than the 4G network, but the cost is that the power consumption of a mobile phone under the 5G network is faster. Therefore, how to save electricity for the terminal is a very painful problem for many mobile phone manufacturers.

Paging is a basic function of the communication system. In the prior art, in order to reduce power consumption of a User Equipment (UE) in an RRC _ IDLE/RRC _ INACTIVE state, the UE receives a paging message in a Discontinuous Reception (DRX) mode.

In Radio Resource Control (RRC) IDLE and Inactive modes, a Paging message is monitored in each DRX cycle, and each DRX cycle monitors a Paging Occasion (PO), which may cause delay to the Paging, so as to consume system resources, and therefore how to reasonably configure the DRX cycle to reduce power consumption and improve the service time of a terminal battery is a problem to be solved.

In an embodiment, fig. 1 is a flowchart of a power saving method for a terminal according to an embodiment of the present invention, which is applicable to a situation when power of the terminal is saved to the maximum extent. The terminal power saving method in the embodiment is applied to a network management center. In this embodiment, the network management center may also be referred to as a base station management center, and is configured to analyze and manage data reported by the base station. As shown in fig. 1, the method specifically comprises the following steps:

s110, determining the actual maximum user number of RRC of the target cell in the preset paging regulation period.

The preconfigured paging regulation cycle refers to a paging message cycle preset on a network management center. The paging adjustment period may be preconfigured manually, and is typically configured at a time granularity, for example, at an hour granularity.

In this embodiment, each base station may correspond to at least one cell, and each cell includes one or more terminals. Each cell corresponds to a corresponding actual maximum number of users of RRC and an average number of users of RRC, where the actual maximum number of users of RRC can be understood as the actual maximum number of users of RRC in the time granularity range of the current cell corresponding to the base station. It should be noted that the maximum number of RRC users that can be carried by the base station is different from the actual maximum number of RRC users of each cell corresponding to the base station, and the actual maximum number of RRC users of each cell corresponding to the base station is constantly changing, and statistics and reporting are performed according to actual conditions. Illustratively, the actual maximum number of users of the current cell in the time granularity range from 1 point to 2 points is 100; the actual maximum number of users from 2 to 3 is 300; the maximum number of users of RRC that can be carried by the base station can be determined according to parameters of the base station, such as performance, number of antennas, transmission power, and the like of the base station.

In this embodiment, each cell calculates the actual maximum number of users and the average number of users of RRC in a time range in real time or at regular time, and sends the number of the actual maximum number of users of RRC to the base station, the base station can count the actual maximum number of users and the average number of users of RRC corresponding to each cell according to the time granularity, and report the number to the network management center, and the network management center counts the actual maximum number of users of RRC of the target cell in a pre-configured paging adjustment period after receiving the average number of users and the actual maximum number of users of RRC reported by the base station in a preset time granularity.

S120, determining a pre-modified DRX period corresponding to the terminal in the target cell according to the pre-configured RRC user capacity value and the corresponding DRX period value as well as the actual maximum user number of the RRC.

The RRC user capacity value may be understood as a threshold value of a preconfigured number of RRC users. The RRC user capacity value may be set empirically or manually, and this embodiment is not limited herein. The pre-modified DRX cycle may be understood as a DRX cycle for which a modification is expected to be needed.

In this embodiment, the RRC user capacity value is configured with a corresponding DRX cycle value. Specifically, the corresponding DRX cycle value may be determined according to a comparison between the RRC user capacity value and a preset threshold value. It should be noted that, when configured RRC user capacity values and corresponding DRX cycle values thereof, corresponding gears may be set, and each gear may correspond to a corresponding RRC user capacity value and a corresponding DRX cycle value thereof.

In this embodiment, according to the determined actual maximum number of users of the RRC, the preconfigured RRC user capacity value and the corresponding DRX cycle value thereof, the pre-modified DRX cycle corresponding to the terminal in the target cell corresponding to the base station may be determined. Specifically, the pre-modification DRX cycle corresponding to the terminal may be determined according to a comparison between the actual maximum number of users of the RRC and the threshold of the user capacity of the RRC. In some embodiments, the pre-modified DRX cycle corresponding to the terminal may be set to a first DRX cycle value when the actual maximum number of users of RRC is greater than or equal to a first threshold value; when the actual maximum number of users of RRC is smaller than a first threshold value and is larger than or equal to a second threshold value, setting a pre-modified DRX period corresponding to the terminal as a second DRX period value; when the actual maximum number of users of the RRC is smaller than the second threshold value and is larger than or equal to the third threshold value, setting the pre-modified DRX period corresponding to the terminal as a third DRX period value; and under the condition that the actual maximum number of the users in the RRC is smaller than the fourth threshold value, setting the pre-modified DRX period corresponding to the terminal as a fourth DRX period value.

S130, synchronizing the pre-modified DRX period to a base station corresponding to the target cell and forwarding the pre-modified DRX period to the terminal by the base station so that the terminal monitors the paging message according to the adjusted DRX period.

In the embodiment, the currently used DRX cycle is compared with the pre-modified DRX cycle by acquiring the currently used DRX cycle of each terminal in the target cell corresponding to the base station, and the currently used DRX cycle can be continuously used without pre-modification under the condition that the comparison result of the currently used DRX cycle is consistent with the pre-modified DRX cycle; and under the condition that the comparison result of the currently used DRX cycle and the pre-modified DRX cycle is inconsistent, the currently used DRX cycle cannot meet the requirement and needs to be modified, and the pre-modified DRX cycle is synchronized to a base station corresponding to the target cell and is forwarded to the terminal by the base station, so that the terminal monitors the paging message according to the adjusted DRX cycle.

In one embodiment, the configuration of the RRC user capacity value and its corresponding DRX cycle value includes:

setting a corresponding DRX period value as a first DRX period value under the condition that the RRC user capacity value is greater than or equal to a first threshold value;

setting a corresponding DRX period value as a third DRX period value under the condition that the RRC user capacity value is greater than or equal to a third threshold value and is less than a second threshold value;

and setting the corresponding DRX period value as a fourth DRX period value under the condition that the RRC user capacity value is smaller than the third threshold value.

The first DRX cycle value refers to a corresponding DRX cycle when the RRC user capacity value is greater than or equal to a first threshold value. The second DRX cycle value refers to a DRX cycle corresponding to the RRC user capacity value being greater than or equal to the second threshold value and less than the first threshold value. The third DRX cycle value refers to a DRX cycle corresponding to the RRC user capacity value being greater than or equal to a third threshold value and less than a second threshold value. And the fourth DRX period value is the corresponding DRX period when the RRC user capacity value is smaller than the third threshold value.

It can be understood that, the larger the RRC user capacity value is, the smaller the corresponding DRX cycle value is, otherwise, the smaller the RRC user capacity value is, the larger the corresponding DRX cycle value is, that is, when the RRC user capacity value is large, the base station may set a small DRX cycle; when the number of users is small, the DRX period with a long length can be set, so that the DRX period can be automatically adjusted according to the number of the users of the RRC, and the purpose of saving electricity for the terminal is achieved.

In this embodiment, when the RRC user capacity value is greater than or equal to the first threshold value, the corresponding DRX cycle value is set as the first DRX cycle value, when the RRC user capacity value is greater than or equal to the second threshold value and less than the first threshold value, the corresponding DRX cycle value is set as the second DRX cycle value, when the RRC user capacity value is greater than or equal to the third threshold value and less than the second threshold value, the corresponding DRX cycle value is set as the third DRX cycle value, and when the RRC user capacity value is less than the third threshold value, the corresponding DRX cycle value is set as the fourth DRX cycle value. Illustratively, the first threshold value is set to 300, the second threshold value is set to 100, the third threshold value is set to 50, and when the RRC user capacity value is greater than or equal to 300, the DRX cycle value is set to 64ms; when the RRC user capacity value is greater than or equal to 100 and less than 300, the DRX period value is set to be 128ms; when the RRC user capacity value is greater than or equal to 50 and less than 100, the DRX period value is set to be 256ms; when the RRC user capacity value is less than 50, the DRX cycle value is set to 512ms.

In an embodiment, the method further comprises:
