The rapid development of communication provides many convenience for our life, and the 5G network speed is faster than the 4G network speed, but the cost is that the mobile phone consumes more power under the 5G network. How to save electricity for the terminal is thus a very painful problem for many handset manufacturers.

Paging is a basic function of a 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 using a discontinuous reception (Discontinuous Reception, DRX) mode. This is so that the UE can wake up only for a fixed time to receive paging messages, and the period of each wake-up is called DRX cycle. In the IDLE and Inactive modes of radio resource control (Radio Resource Control, RRC), paging messages are monitored in each DRX cycle, each DRX cycle monitors a Paging Occasion (PO), and DRX delays Paging, so that system resources are consumed, so how to reasonably configure the DRX cycle to achieve power consumption reduction and increase the service time of a terminal battery is a problem to be solved.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In an embodiment, fig. 1 is a flowchart of a method for saving power of a terminal according to an embodiment of the present invention, where the embodiment is applicable to a situation when power of the terminal is saved maximally. 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 specific steps include:

s110, determining the RRC actual maximum number of users of the target cell in the preconfigured paging adjustment period.

The preconfigured paging adjustment period refers to a preset paging message period on the network management center. The paging adjustment period may be preconfigured manually, and typically, the paging adjustment period is configured with a time granularity, and illustratively, the paging adjustment period is configured with 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 RRC actual maximum number of users and an RRC average number of users, where the RRC actual maximum number of users may be understood as an actual RRC maximum number of users of the base station corresponding to the current cell in a time granularity range. It should be noted that, the maximum number of RRC users that can be borne 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 continuously changed, and is reported statistically according to the actual situation. Exemplary, the actual maximum number of users in the current cell in the 1-point to 2-point time granularity range is 100; the actual maximum number of users in 2 points to 3 points is 300, etc.; the maximum number of RRC users that can be carried by the base station may be determined according to parameters of the base station, for example, performance of the base station, the number of antennas, transmission power, and so on.

In this embodiment, each cell calculates the RRC actual maximum user number and the RRC average user number in the time range in real time or in a fixed time, and sends the RRC actual maximum user number and the RRC average user number that can be calculated by the RRC to the base station, the base station may count the RRC actual maximum user number and the RRC average user number corresponding to each cell according to the time granularity, and report the RRC actual maximum user number and the RRC average user number to the network management center, where the network management center receives the RRC average user number and the RRC actual maximum user number reported by the base station in the preset time granularity, and counts the RRC actual maximum user number of the target cell in the preset paging adjustment period.

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

The RRC user capacity value may be understood as a threshold value of the number of RRC users that are preconfigured. The RRC user capacity value may be set empirically, or may be set manually or by itself, which is not limited in this embodiment. A pre-modified DRX cycle may be understood as a DRX cycle that is expected to need modification.

In this embodiment, when the RRC user capacity value is configured, a corresponding DRX cycle value corresponds to the RRC user capacity 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 the configured RRC user capacity value and the DRX cycle value corresponding thereto, a gear corresponding thereto may be set, and each gear may correspond to the corresponding RRC user capacity value and the DRX cycle value corresponding thereto.

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

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

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

In an 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 larger than or equal to a first threshold value;

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

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

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

It should be noted that, the threshold values corresponding to the first threshold value, the second threshold value and the third threshold value respectively decrease in sequence, that is, the first threshold value is greater than the second threshold value and greater than the third threshold value; and the cycle values respectively corresponding to the first DRX cycle value, the second DRX cycle value, the third DRX cycle value and the fourth DRX cycle value are sequentially increased, namely that the first DRX cycle value is larger than the second DRX cycle value and larger than the third DRX cycle value and larger than the fourth DRX cycle value. It can be understood that the larger the RRC user capacity value, the smaller the corresponding DRX cycle value, whereas the smaller the RRC user capacity value, the larger the corresponding DRX cycle value, i.e., the smaller the DRX cycle can be set when the base station has more RRC user capacity values; when the number of users is small, a long DRX period can be set, so that the DRX period can be automatically adjusted according to the number of RRC users, 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 to be 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 to be 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 to be 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 to be 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 the DRX cycle value is set to 64ms when the RRC user capacity value is greater than or equal to 300; when the RRC user capacity value is greater than or equal to 100 and the RRC user capacity value is less than 300, setting the DRX cycle value to 128ms; when the RRC user capacity value is greater than or equal to 50 and the RRC user capacity value is less than 100, the DRX cycle value is set to 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:

and adjusting the pre-configured RRC user capacity value and the corresponding DRX period value according to the pre-established RRC user quantity statistical model to obtain the adjusted RRC user capacity value and the corresponding DRX period value.

The RRC user number statistical model may be understood as a historical RRC user number statistical model of each cell of the base station, and the RRC user number statistical model may include: radio resource control RRC user hour statistical model, radio resource control RRC user day statistical model, radio resource control RRC user week statistical model and radio resource control RRC user month statistical model

In one embodiment, the pre-established RRC user number statistical model includes one of: the establishing of the RRC user hour statistical model, the RRC user daily statistical model, the RRC user week statistical model and the RRC user month statistical model comprises the following steps:

In an embodiment, fig. 2 is a flowchart of another power saving method for a terminal according to an embodiment of the present invention, where the method determines an RRC actual maximum user number of a target cell in a preconfigured paging adjustment period based on the foregoing embodiments, determines a pre-modified DRX cycle corresponding to the terminal in the target cell according to a preconfigured RRC user capacity value and a DRX cycle value corresponding to the RRC user capacity value, and the RRC actual maximum user number, and synchronizes the pre-modified DRX cycle to a base station corresponding to the target cell and forwards the pre-modified DRX cycle to the terminal by the base station, so that the terminal further refines a paging message monitored by the terminal according to the adjusted DRX cycle.

The terminal power saving method in the embodiment is applied to a network management center. As shown in fig. 2, the terminal power saving method in this embodiment may specifically include the following steps:

s210, receiving the average number of RRC users and the actual maximum number of RRC users reported by the base station in a preset time granularity.

The preset time granularity refers to a time granularity of reporting the average number of RRC users and the actual maximum number of RRC users of the corresponding cell by the base station, and the time granularity is generally set to be a minute time granularity, and exemplary, the preset time granularity is 10 minutes, 15 minutes, and the like.

In this embodiment, after the terminal user accesses to the corresponding base station, each cell calculates the corresponding RRC average user number and RRC actual maximum user number in real time or at a fixed time, and the base station calculates the corresponding RRC average user number and RRC actual maximum user number in real time or at a fixed time in a preset time granularity, and reports the calculated RRC average user number and RRC actual maximum user number to the network management center, and the network management center receives the RRC average user number and RRC actual maximum user number reported by the base station and performs corresponding statistics.

S220, counting the RRC actual maximum user number corresponding to the target cell in a preset time granularity in a preset paging adjustment period, wherein the preset paging adjustment period is larger than the preset time granularity.

In this embodiment, when receiving the average number of RRC users and the actual maximum number of RRC users corresponding to each cell reported by the base station according to the preset time granularity, the network management center may count the actual maximum number of RRC users corresponding to each cell in the preset paging adjustment period. It should be noted that, the preconfigured paging adjustment period is greater than the preset time granularity, and it is understood that the preconfigured paging adjustment period is generally in the time granularity of hours, and the preset time granularity is generally in the time granularity of minutes.

And S230, setting the pre-modification DRX period corresponding to the terminal as a first DRX period value under the condition that the RRC actual maximum user number is greater than or equal to a first threshold value.

In this embodiment, the network management center obtains the pre-modified DRX cycle corresponding to the target cell according to the RRC actual maximum number of users counted by the target cell in the paging adjustment cycle. Specifically, when the RRC actual maximum number of users corresponding to the target cell in the preconfigured paging adjustment period is greater than or equal to the first threshold, the preconfigured DRX periods corresponding to all terminals in each cell may be set to a first DRX period value. For example, when the RRC actual maximum number of users is 200 and the first threshold is 100 and the corresponding first DRX cycle value is 32ms, the pre-modified DRX cycles corresponding to all terminals in each cell are set to 32ms.

S240, setting the pre-modification DRX period corresponding to the terminal as a second DRX period value under the condition that the RRC actual maximum user number is smaller than the first threshold value and larger than or equal to the second threshold value.

In this embodiment, the network management center obtains the pre-modified DRX cycle corresponding to the target cell according to the RRC actual maximum number of users counted by the target cell in the paging adjustment cycle. Specifically, when the RRC actual maximum number of users corresponding to the target cell in the preconfigured paging adjustment period is smaller than the first threshold and is greater than or equal to the second threshold, the preconfigured DRX periods corresponding to all terminals in each cell may be set to the second DRX period value. For example, when the RRC actual maximum number of users is 80, the first threshold is 100, the second threshold is 60, and the corresponding first DRX cycle value is 64ms, the pre-modified DRX cycles corresponding to all terminals in each cell are set to 64ms.

S250, setting the pre-modification DRX period corresponding to the terminal as a third DRX period value under the condition that the RRC actual maximum user number is smaller than a second threshold value and is larger than or equal to a third threshold value.

In this embodiment, the network management center obtains the pre-modified DRX cycle corresponding to the target cell according to the RRC actual maximum number of users counted by the target cell in the paging adjustment cycle. Specifically, when the RRC actual maximum number of users corresponding to the target cell in the preconfigured paging adjustment period is smaller than the second threshold and is greater than or equal to the third threshold, the preconfigured DRX periods corresponding to all terminals in each cell may be set to a third DRX period value. For example, when the RRC actual maximum number of users is 45, the third threshold is 30, the second threshold is 60, and the corresponding first DRX cycle value is 128ms, the pre-modified DRX cycles corresponding to all terminals in each cell are set to 128ms.

And S260, setting the pre-modification DRX period corresponding to the terminal as a fourth DRX period value under the condition that the RRC actual maximum user number is smaller than a third threshold value.

In this embodiment, the network management center obtains the pre-modified DRX cycle corresponding to the target cell according to the RRC actual maximum number of users counted by the target cell in the paging adjustment cycle. Specifically, when the RRC actual maximum number of users corresponding to the target cell in the preconfigured paging adjustment period is smaller than the third threshold, the preconfigured DRX periods corresponding to all terminals in each cell may be set to a fourth DRX period value. For example, when the RRC actual maximum number of users is 20 and the third threshold is 30 and the corresponding first DRX cycle value is 256ms, the pre-modified DRX cycles corresponding to all terminals in each cell are set to 256ms.

S270, judging whether the pre-modified DRX period of the terminal in the target cell is consistent with the DRX period currently used by the terminal in the target cell, if so, executing S280; if not, S290 is performed.

In this embodiment, the network management center determines whether the DRX cycle of the target cell needs to be adjusted currently, specifically, compares the pre-modified DRX cycle corresponding to the terminal in the target cell with the DRX cycle currently used by the terminal in the target cell, and if the pre-modified DRX cycle is consistent with the DRX cycle currently used, does not need to adjust the DRX cycle of the terminal in the target cell; if the pre-modification DRX period is inconsistent with the currently used DRX period, a DRX period adjustment flow is required to be started, the default paging period carried in the message parameter corresponding to the modification target cell is the pre-modification DRX period, and the pre-modification DRX period is synchronized to the base station, so that the base station triggers the parameter modification flow of the message parameter when monitoring that the DRX period is modified, and the message parameter is forwarded to the terminal by the base station.

S280, the DRX cycle of the terminal in the target cell is not adjusted.

In this embodiment, in the case that the pre-modified DRX cycle is consistent with the currently used DRX cycle, the adjustment DRX cycle procedure does not need to be started to perform adjustment of the DRX cycle of the terminal in the target cell.

S290, modifying the default paging cycle carried in the message parameter corresponding to the target cell as a pre-modification DRX cycle, and synchronizing the pre-modification DRX cycle to the base station, so that the base station triggers the parameter modification flow of the message parameter when the base station monitors that the DRX cycle is modified, and the message parameter modification flow is forwarded to the terminal by the base station.

In this embodiment, when the pre-modification DRX cycle is inconsistent with the currently used DRX cycle, a DRX cycle adjustment procedure needs to be started to modify the DRX cycle of the terminal in the target cell, first, the default paging cycle carried in the message parameter corresponding to the target cell is modified to be the pre-modification DRX cycle, and the pre-modification cycle is triggered to be synchronized to the base station, so that the base station triggers the parameter modification procedure of the message parameter when detecting that the DRX cycle is modified, and the base station triggers the parameter modification procedure of the signaling message parameter when detecting that the DRX cycle is modified, and forwards the pre-modification DRX cycle to the terminal.

According to the technical scheme, under the condition that the RRC actual maximum user number is larger than or equal to the first threshold value, the pre-modification DRX cycle corresponding to the terminal is set to be the first DRX cycle value, under the condition that the RRC actual maximum user number is smaller than the first threshold value and larger than or equal to the second threshold value, the pre-modification DRX cycle corresponding to the terminal is set to be the second DRX cycle value, under the condition that the RRC actual maximum user number is smaller than the second threshold value and larger than or equal to the third threshold value, the pre-modification DRX cycle corresponding to the terminal is set to be the third DRX cycle value, under the condition that the RRC actual maximum user number is smaller than the third threshold value, the pre-modification DRX cycle corresponding to the terminal is set to be the fourth DRX cycle value, whether the pre-modification DRX cycle of the terminal in the target cell is consistent with the current use cycle of the terminal is judged, under the condition that the RRC actual maximum user number is larger than or equal to the second threshold value, the default paging cycle carried in the message parameter corresponding to the target cell is set to be the pre-modification DRX cycle, the pre-modification DRX cycle is synchronized to the base station under the condition that the RRC actual maximum user number is smaller than the second threshold value, the DRX cycle is larger than the third threshold value, the message parameter is set to be the first DRX cycle is triggered to the terminal, and the idle condition is further adjusted by the base station is reached, and the method is capable of saving the power source parameters.

In an embodiment, fig. 3 is a flowchart of another power saving method for a terminal according to an embodiment of the present invention, where the power saving method for a terminal in the embodiment is applied to a base station. As shown in fig. 3, the terminal power saving method in this embodiment may specifically include the following steps:

s310, receiving the pre-modified DRX cycle issued by the network management center.

S320, paging the terminal in each cell, and notifying the terminal that the DRX cycle is updated.

S330, at the moment of sending the message parameters, the updated message parameters are sent to the terminal, so that when the terminal monitors the updating of the paging message, the updated message parameters are read, and the DRX cycle in use is updated according to the pre-modified DRX cycle contained in the updated message parameters.
