Description

Equipment energy saving method, communication device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an apparatus energy saving method, a communication apparatus, and a storage medium.

Background

Currently, the main method for saving energy of equipment is deep sleep energy saving. The specific process of saving energy of the equipment by adopting deep dormancy comprises the following steps: the baseband processing unit (BBU) detects whether the cell #1 satisfies an energy saving condition (for example, the energy saving condition is generally that the number of terminal devices in the cell #1 is 0). If the cell #1 satisfies the above energy saving condition, the BBU instructs all Remote Radio Units (RRUs) under the cell #1 to enter a deep sleep mode (e.g., low power operation).

The method for saving energy of the equipment by adopting deep dormancy energy saving is carried out by taking a cell as granularity. The BBU can only indicate that all RRUs in the cell enter the deep sleep mode, or that all RRUs in the cell do not enter the deep sleep mode. In some scenarios (for example, there is no data transmission in part of the RRUs under the cell #1, and there is data transmission in another part of the RRUs under the cell # 1), since the BBU can only indicate with the cell as granularity, as long as there is data transmission in the whole cell #1, the BBU cannot indicate all the RRUs under the cell #1 to perform energy saving operation, which will cause the efficiency of device energy saving to be reduced, and affect the effect of device energy saving.

Disclosure of Invention

The application provides an equipment energy-saving method, a communication device and a storage medium, which can improve the energy-saving efficiency of equipment and optimize the energy-saving effect of the equipment.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a device energy saving method, including: acquiring first data from an RRU; the first data of the RRU comprises at least one of: the method comprises the steps of identifying equipment identification of first terminal equipment, signal strength of the first terminal equipment, service volume of the first terminal equipment, the number of the first terminal equipment, service identification of the first terminal equipment and identification of RRU (remote radio unit); the first terminal equipment is connected with the RRU; and under the condition that the first data of the RRU meets the preset energy-saving condition, indicating the RRU to start an energy-saving state.

The technical scheme at least has the following beneficial effects: according to the equipment energy saving method provided by the application, the BBU receives the first data from the RRU. The first data includes at least one of: the device identifier of the first terminal device, the signal strength of the first terminal device, the traffic of the first terminal device, the number of the first terminal devices, and the identifier of the RRU. BUU, it can be determined whether the RRU can start the power saving state according to at least one of the device identifier of the first terminal device, the signal strength of the first terminal device, the traffic volume of the first terminal device, and the number of the first terminal device. If so, the BBU can trigger the energy-saving state of the RRU according to the identification of the RRU carried in the first data, so that the BBU can perform energy-saving operation on a single RRU without issuing energy-saving indication by using a cell as granularity, thereby greatly improving the energy-saving efficiency of the equipment and enhancing the energy-saving effect of the equipment.

In one possible implementation, it is determined whether the first data satisfies at least one of: whether the number of the first terminal equipment is smaller than or equal to a first preset threshold value or not and whether the traffic of the first terminal equipment is smaller than or equal to a second preset threshold value or not; if so, indicating the RRU to transmit data at a first preset power; the first preset power is smaller than the power of the current transmission data of the RRU. In this implementation, the BBU first determines whether the first data satisfies at least one of: if the BBU determines that the number of the first terminal devices in the first data of the RRU is less than or equal to a first preset threshold and the service volume of the first terminal devices is less than or equal to a second preset threshold, and/or if the service volume of the first terminal devices is less than or equal to the second preset threshold, the BBU can instruct the RRU to start an energy-saving state (i.e. transmit data with first preset power), so that the BBU can perform energy-saving operation on a single RRU without issuing an energy-saving instruction with a cell as a granularity, thereby greatly improving the energy-saving efficiency of the device and enhancing the energy-saving effect of the device.

In a possible implementation manner, under the condition that the current time is within a preset time period, determining a second terminal device in the first terminal device according to a device identifier of the first terminal device; the second terminal equipment is connected with the RUU and does not sign the energy-saving service; determining third data of the RRU; the third data includes: the number of the second terminal devices and the traffic of the second terminal devices; determining whether the third data satisfies at least one of: whether the number of the second terminal equipment is less than or equal to a first preset threshold value or not and whether the traffic of the second terminal equipment is less than or equal to a second preset threshold value or not; and if so, indicating the RRU to transmit data at a first preset power. In this implementation manner, if the BBU determines that the number of the first terminal devices in the first data of the RRU is greater than a first preset threshold, and/or the traffic volume of the first terminal device is greater than a second preset threshold, in a preset time period, the BBU may remove a third terminal device in the first terminal device according to the device identifier of the first terminal device, determine a second terminal device in the first terminal device, and then determine that data including the number of the second terminal device and the traffic volume of the second terminal device is third data. The BBU determines whether the third data meets at least one of the following conditions: whether the number of the second terminal devices is smaller than a first preset threshold value or not and whether the traffic of the second terminal devices is smaller than a second preset threshold value or not. If so, the BBU may also instruct the RRU to enter a state of transmitting data at a first preset power, so that in the determination of whether the RRU is in an energy-saving state, consideration is added to the terminal equipment signing the energy-saving service, the terminal equipment signing the energy-saving service may be removed within a preset time period, and only the number and the traffic of the terminal equipment not signing the energy-saving service (i.e., the second terminal equipment) need to be determined, and if the number of the second terminal equipment is less than or equal to a first preset threshold, and/or the traffic of the second terminal equipment is less than or equal to a second preset threshold, the BBU may still instruct the RRU to transmit data at the first preset power, further improving the efficiency of equipment energy saving, and further optimizing the effect of equipment energy saving.

In one possible implementation, it is determined whether the first data satisfies at least one of: whether the signal intensity of the first terminal equipment is greater than or equal to a third preset threshold value or not and whether the traffic of the first terminal equipment is less than or equal to a fourth preset threshold value or not; if yes, instructing the RRU to close the first preset number of data transmission channels; the first preset quantity is determined according to the signal intensity of the first terminal device and the traffic of the first terminal device. In this implementation, the BBU determines whether the first data satisfies at least one of: whether the signal intensity of the first terminal equipment in the first data of the RRU is greater than a third preset threshold value or not and whether the traffic volume of the first terminal equipment in the first data of the RRU is less than a fourth preset threshold value or not. If so, the BBU may instruct the RRU to turn on the power saving state (i.e., turn off the first preset number of data transmission channels). When the data transmission channel is closed, the signal coverage area of the RRU is reduced to a certain extent, which may cause the signal strength of the remote first terminal device (that is, the terminal device located at the edge of the signal coverage area of the RRU) to be reduced, so that, in the process of determining whether the RRU is in the energy-saving state, the BBU needs to determine not only the traffic of the first terminal device but also the signal strength of the first terminal device, so that, in the case that the RRUs close the first preset number of data transmission channels, the signal strength of the remote first terminal device may not be reduced below the signal strength threshold value, and the problem of call drop of the remote first terminal device caused by the fact that the signal strength of the remote first terminal device is lower than the signal strength threshold value in the process of performing the energy-saving operation on a single RRU is avoided.

In a possible implementation manner, whether a preset service exists in the service of the first terminal device is determined according to the service identifier of the first terminal device; if not, determining whether the first data meets at least one of the following: whether the number of the first terminal equipment is less than or equal to a fifth preset threshold value or not and whether the traffic of the first terminal equipment is less than or equal to a sixth preset threshold value or not; if yes, instructing the RRU to close the downlink subframes with the second preset number and the radio frequency channels with the third preset number; the second preset quantity and the third preset quantity are determined according to the quantity of the first terminal equipment and the traffic of the first terminal equipment. In this implementation, the BBU first determines whether the first data satisfies at least one of: and if not, determining whether the number of the first terminal equipment is less than a fifth preset threshold or not by the BBU, and if so, indicating to close the downlink subframes with the second preset number and indicating to close the radio frequency channels with the third preset number by the BBU, so that the energy-saving efficiency of the equipment is further improved, and the energy-saving effect of the equipment is further optimized.

With the rapid development of the fifth generation mobile communication technology (5G), 5G is going to be fully commercialized, and the number of 5G small access network devices in commercial use is going to reach 1310 ten thousand, so that the number of 5G small access network devices in commercial use accounts for 1/3% of the number of all small access network devices. It is expected that after a while, the data of the 5G small access network devices will exceed the number of 4th generation mobile communication technology (4G) small access network devices. Although the performance of the 5G small access network device is better than that of the 4G small access network device, the power consumption of the 5G small access network device is higher than that of the 4G small access network device due to the increased power consumption of the active antenna unit of the 5G small access network device. In general, the energy consumption of a 5G small access network device is 2.5 times to 3.5 times that of a 4G small access network device. Therefore, the problem of high energy consumption of the 5G small access network device is a technical problem to be solved urgently by those skilled in the art.

Currently, the main method for equipment energy conservation is site-level energy conservation as described above. Illustratively, the specific implementation process of performing device energy saving by using deep sleep energy saving in the site level energy saving includes: in one detection cycle, the BBU detects whether the cell #1 satisfies the energy saving condition (for example, the energy saving condition is generally that the number of terminal devices under the cell #1 is 0). If the cell #1 meets the energy saving condition, the BBU instructs all the RRUs in the cell #1 to enter a deep sleep mode (e.g., low power operation) within a preset energy saving time period (the preset energy saving time period is determined according to the start time and stop time set by the BBU). If the cell #1 does not satisfy the energy saving condition, the BBU may detect the cell #1 again in the next detection period.

However, the above method for saving energy of devices by deep sleep is performed with the granularity of a cell. The BBU can only indicate that all RRUs in the cell enter the deep sleep mode, or that all RRUs in the cell do not enter the deep sleep mode. In some scenarios (for example, there is no data transmission in part of the RRUs under the cell #1, and there is data transmission in another part of the RRUs under the cell # 1), since the BBU can only indicate with the cell as granularity, as long as there is data transmission in the whole cell #1, the BBU cannot indicate all the RRUs under the cell #1 to perform energy saving operation, which will cause the efficiency of device energy saving to be reduced, and affect the effect of device energy saving.

In order to solve the problems in the prior art, an embodiment of the present application provides an apparatus energy saving method, which can improve the efficiency of apparatus energy saving. As shown in fig. 4, the method includes:

s401, the RRU sends first data to the BBU. Correspondingly, the BBU acquires first data from the RRU.

Wherein the first data of the RRU comprises at least one of: the device identifier of the first terminal device, the signal strength of the first terminal device, the traffic of the first terminal device, the number of the first terminal devices, the service identifier of the first terminal device, and the identifier of the RRU. The first terminal device is a terminal device connected with the RRU.

It should be noted that the device identifier of the first terminal device may be an International Mobile Subscriber Identity (IMSI). The Signal strength of the first terminal device may be a Reference Signal Receiving Power (RSRP).

Optionally, the first data may further include: signal to Interference plus Noise Ratio (SINR) of the first terminal device. The first data may further include other information, and the application does not limit the first data in any way.

It should be noted that the RRU of the present application includes: l1-a function of a PHY layer, a function of counting the number of the first terminal devices, and a function of analyzing service data reported by the first terminal devices.

If the RRUs are obtained by dividing the RRUs according to the option6, an operation developer does not need to add the functions of the L1-PHY layer (i.e., the L1-PHY-high layer and the L1-PHY-low layer) to the RUU. If the RRUs are obtained by dividing the RRUs according to the option7, an operation developer needs to add the function of the L1-PHY-high layer to the RUU. If the RRUs are obtained by dividing the RRUs according to the option8, an operation developer needs to add the function of the L1-PHY layer to the RUU. Thus, no matter what division mode is based on, the RRU of the present application includes the functions of the L1-PHY layer. The RUU (i.e., RRU of the present application) including the functionality of the L1-PHY layer has data parsing capability. For example, the data is subjected to a decoding process.

On the basis that the RRU comprises the function of an L1-PHY layer, an operation developer adds the function of counting the number of the first terminal equipment and the function of analyzing the service data reported by the first terminal equipment to the RRU.

It should be noted that the first terminal device includes: the terminal equipment is connected with the RRU and signs the energy-saving service, and the terminal equipment is connected with the RRU and does not sign the energy-saving service.

S402, under the condition that first data of the RRU meet a preset energy-saving condition, the BBU indicates the RRU to start an energy-saving state.

It should be noted that, the specific implementation process of S402 is as follows: and the BBU determines whether the RRU meets a preset energy-saving condition or not according to at least one of the equipment identifier of the first terminal equipment, the signal strength of the first terminal equipment, the service volume of the first terminal equipment, the number of the first terminal equipment and the service identifier of the first terminal equipment. If the first data of the RRU meets the preset energy saving condition, the BBU may indicate, according to the identifier of the RRU, that the RRU corresponding to the identifier of the RRU starts an energy saving state.

It is noted that the BBU can set an energy saving time period. The energy-saving time period is used for defining the time period when the RRU is in the energy-saving state. For example, the BBU sets the above-described energy saving period to one hour. The energy-saving time period can be set by the BBU according to actual conditions, and the preset time period is not limited in any way in the application.

It should be noted that the device energy saving method provided by the present application can be applied to the following three scenarios: scene 1, a scene for saving energy of equipment through deep dormancy energy saving; scene 2, a scene for saving energy of equipment by closing energy saving channels; and scene 3, a scene for performing equipment energy saving by sub-frame energy saving turning off. The specific implementation process of S402 is different in different scenarios (e.g., scenario 1, scenario 2, and scenario 3). A specific implementation of S402 in the above-described scenarios 1, 2, and 3 will be described in detail below.

In scenario 1, as shown in fig. 5, S402 described above may be implemented by the following S501-S502.

S501, determining whether the first data meets at least one of the following conditions by the BBU: whether the number of the first terminal equipment is smaller than or equal to a first preset threshold value or not and whether the traffic of the first terminal equipment is smaller than or equal to a second preset threshold value or not.

The traffic of the first terminal device is the sum of the traffic of all the first terminal devices included in the first data.

Illustratively, the BBU may set the first preset threshold to 0 and the second preset threshold to 0 Terabyte (Tb) as well. The above is only an example of the first preset threshold and the second preset threshold, and the first preset threshold and the second preset threshold are not limited in any way in the present application.

If the BBU determines that the number of the first terminal devices is smaller than a first preset threshold, and/or the traffic volume of the first terminal devices is smaller than a second preset threshold, the BBU executes S502.

S502, the BBU indicates the RRU to transmit data with a first preset power.

The first preset power is smaller than the power of the current transmission data of the RRU.

For example, if the power of currently transmitted data by the RRU is 33 decibel milliwatts (dBm), the BBU may set the first preset power device to 10 dBm.

The technical scheme at least brings the following beneficial effects: in the device energy saving method provided by the application, the BBU first determines whether the first data satisfies at least one of the following: if the BBU determines that the number of the first terminal devices in the first data of the RRU is less than or equal to a first preset threshold and the traffic of the first terminal devices is less than or equal to a second preset threshold, and/or if the traffic of the first terminal devices is less than or equal to the second preset threshold, the BBU can instruct the RRU to start an energy-saving state (namely, transmit data with first preset power), so that the BBU can perform energy-saving operation on a single RRU without issuing energy-saving instructions with a cell as a granularity, thereby greatly improving the energy-saving efficiency of the device and enhancing the energy-saving effect of the device.

In a possible implementation manner, referring to fig. 5, as shown in fig. 6, in a case that the number of the first terminal devices is greater than or equal to a first preset threshold, and/or the traffic volume of the first terminal device is greater than or equal to a second preset threshold, the above S402 may be implemented by the following S601-S604.

S601, under the condition that the current time is within a preset time period, determining a second terminal device in the first terminal device by the BBU according to the device identifier of the first terminal device.

And the second terminal equipment is connected with the RUU and does not sign the energy-saving service.

In a possible implementation manner, the specific implementation process of S601 may be: the BBU determines, from the first terminal devices, that a first terminal device identified as a first identifier (i.e., a device identifier of a terminal device that has not subscribed to an energy saving service) is a second terminal device.

In another possible implementation manner, the specific implementation process of S601 may be: the BBU determines, from the first terminal devices, that the first terminal device identified as the second identifier (i.e., the device identifier of the terminal device that has signed up for the energy saving service) is the third terminal device (i.e., the terminal device that is connected to the RUU and has signed up for the energy saving service). And removing the third terminal equipment from the first terminal equipment by the BBU, wherein the obtained remaining first terminal equipment is the second terminal equipment.

It is noted that the BBU can set the above-described time period as a time period in which the communication system is relatively idle. For example, the BBU sets the above-mentioned preset time period to 0:00-4: 00.

S602, the BBU determines third data of the RRU.

Wherein the third data includes: the number of second terminal devices and the traffic volume of the second terminal devices.

It should be noted that, the specific implementation process of S602 is as follows: the BBU may count the number of the determined second terminal devices, and obtain the traffic volume of the second terminal devices from the first data. And the BBU determines that the data comprising the number of the second terminal equipment and the traffic of the second terminal equipment is third data.

S603, the BBU determines whether the third data meets at least one of the following conditions: whether the number of the second terminal devices is smaller than a first preset threshold value or not and whether the traffic of the second terminal devices is smaller than a second preset threshold value or not.

It should be noted that the terminal device may determine whether to sign the energy saving service according to the traffic of the terminal device. If the terminal device determines to sign the energy saving service, the terminal device may be ignored (i.e., the terminal device is regarded as a non-access user) within the preset time period. Therefore, in the process of determining whether the first data of the RRU satisfies the preset energy saving condition, the BBU may eliminate a third terminal device (i.e., a terminal device connected to the RUU and subscribing to the energy saving service) from the first terminal device, and only reserve a second terminal device (i.e., a terminal device connected to the RUU and not subscribing to the energy saving service).

If the BBU determines that the number of the second terminal devices is smaller than the first preset threshold, and/or the traffic volume of the second terminal devices is smaller than the second preset threshold, the BBU executes S604.

S604, the BBU indicates the RRU to transmit data with a first preset power.

It should be noted that S604 can be understood with reference to S502 described above, and is not described herein again.

Optionally, when the BBU determines that the number of the second terminal devices is greater than or equal to the first preset threshold, and/or the traffic volume of the second terminal devices is greater than or equal to the second preset threshold, the BBU may determine the number of the second terminal devices in the next detection period.

Illustratively, in scenario 1, the BBU may set the above-described detection period to 5 minutes.

The technical scheme at least has the following beneficial effects: according to the device energy saving method provided by the application, if the BBU determines that the number of the first terminal devices in the first data of the RRU is larger than a first preset threshold value and/or the traffic of the first terminal devices is larger than a second preset threshold value, in a preset time period, the BBU can remove third terminal devices in the first terminal devices according to the device identifiers of the first terminal devices, determine second terminal devices in the first terminal devices, and then determine that data including the number of the second terminal devices and the traffic of the second terminal devices are third data. The BBU determines whether the third data satisfies at least one of the following conditions: whether the number of the second terminal devices is smaller than a first preset threshold value or not and whether the traffic of the second terminal devices is smaller than a second preset threshold value or not. If so, the BBU may also instruct the RRU to enter a state of transmitting data at a first preset power, so that in the determination of whether the RRU is in an energy-saving state, consideration is added to the terminal equipment signing the energy-saving service, the terminal equipment signing the energy-saving service may be removed within a preset time period, and only the number and the traffic of the terminal equipment not signing the energy-saving service (i.e., the second terminal equipment) need to be determined, and if the number of the second terminal equipment is less than or equal to a first preset threshold, and/or the traffic of the second terminal equipment is less than or equal to a second preset threshold, the BBU may still instruct the RRU to transmit data at the first preset power, further improving the efficiency of equipment energy saving, and further optimizing the effect of equipment energy saving.

In scenario 2, as shown in fig. 7, the above S402 may be implemented by the following S701-S702.

S701, determining whether the first data meets at least one of the following conditions by the BBU: whether the signal intensity of the first terminal device is greater than a third preset threshold value and whether the traffic volume of the first terminal device is less than a fourth preset threshold value.

The signal strength of the first terminal device refers to the signal strength of any one of all the first terminal devices included in the first data.

It should be noted that the BBU may set the third preset threshold and the fourth preset threshold according to actual situations. For example, the BBU may set the third preset threshold to-90 dbm and the fourth preset threshold to 100 Tb. The above is only an example of the third preset threshold and the fourth preset threshold, and the third preset threshold and the fourth preset threshold are not limited in any way in the present application.

If the BBU determines that the signal intensity of the first terminal device is greater than the third preset threshold, and/or the traffic volume of the first terminal device is less than the fourth preset threshold, the BBU executes S702.

S702, the BBU indicates the RRU to close the first preset number of data transmission channels.

The first preset quantity is determined by the BBU according to the signal intensity of the first terminal equipment and the traffic of the first terminal equipment.

It should be noted that the data transmission channel may include at least one of the following: vertical channels, horizontal channels, and polarized channels.

It should be noted that, if the signal strength of the first terminal device is higher or the traffic of the first terminal device is less, the value of the first preset number set by the BBU is larger.

For example, the BBU may set the first preset number to 1 in case the signal strengths of the first terminal devices are all greater than-88 dbm, or the sum of the traffic of the first terminal devices is 85 Tb.

As yet another example, the BBU may set the first preset number to 2 in case the signal strengths of the first terminal devices are all greater than-78 dbm, or the sum of the traffic of the first terminal devices is 63 Tb.

Optionally, when the BBU determines that the signal strength of the first terminal device is less than or equal to a third preset threshold, and/or the traffic volume of the first terminal device is greater than or equal to a fourth preset threshold, the BBU may determine the signal strength of the first terminal device and the traffic volume of the first terminal device in a next detection period.

Illustratively, in scenario 2, the BBU may set the above-described detection period to 6 minutes.

Optionally, in a time period when the RRU closes the first preset number of data transmission channels, the BBU may perform centralized scheduling on the service of the first terminal device in the time period, so that the service of the first terminal device may operate in a specific time period, thereby avoiding that the service of the first terminal device is ignored and service experience of the terminal device is affected, and in a case of performing centralized scheduling on the service of the first terminal device, the BBU may increase a time when the RRU closes the first preset number of data transmission channels, so that efficiency of saving energy of the device may be further improved.

The technical scheme at least has the following beneficial effects: in the device energy saving method provided by the application, the BBU determines whether the first data satisfies at least one of the following: whether the signal intensity of the first terminal equipment in the first data of the RRU is greater than a third preset threshold value or not and whether the traffic volume of the first terminal equipment in the first data of the RRU is less than a fourth preset threshold value or not. If so, the BBU may instruct the RRU to turn on the power saving state (i.e., turn off the first preset number of data transmission channels). When the data transmission channel is closed, the signal coverage area of the RRU is reduced to a certain extent, which may cause the signal strength of the remote first terminal device (that is, the terminal device located at the edge of the signal coverage area of the RRU) to be reduced, so that, in the process of determining whether the RRU is in the energy-saving state, the BBU needs to determine not only the traffic of the first terminal device but also the signal strength of the first terminal device, so that, in the case that the RRUs close the first preset number of data transmission channels, the signal strength of the remote first terminal device may not be reduced below the signal strength threshold value, and the problem of call drop of the remote first terminal device caused by the fact that the signal strength of the remote first terminal device is lower than the signal strength threshold value in the process of performing the energy-saving operation on a single RRU is avoided.

In scenario 3, as shown in fig. 8, the above S402 can be implemented by the following S801 to S803.

S801, determining whether a preset service exists in the service of the first terminal equipment by the BBU according to the service identification of the first terminal equipment.

The preset service may be a service with a high requirement on time delay.

It should be noted that, because the service level of the service with a higher requirement for the delay (which may be referred to as a delay sensitive service) is higher, if the service of the first terminal device includes the service with a higher requirement for the delay, the BBU cannot instruct the RRU to start the energy saving state, so as to avoid affecting the normal operation of the service with a higher requirement for the delay.

It should be noted that the foregoing S801 and the specific implementation process are as follows: and the BBU determines whether the service identifier of each first terminal device included in the first data includes the service identifier of the delay sensitive service.

And if the service identifier of the first terminal equipment determines that the preset service exists in the service of the first terminal equipment, the BBU finishes the energy-saving process of the equipment.

If the service identifier of the first terminal device determines that no preset service exists in the service of the first terminal device, the BBU executes S802.

S802, the BBU determines whether the first data meets at least one of the following conditions: whether the number of the first terminal devices is smaller than a fifth preset threshold value or not and whether the traffic of the first terminal devices is smaller than a sixth preset threshold value or not.

It should be noted that the BBU may set a fifth preset threshold and a sixth preset threshold according to an actual situation. For example, the BBU may set the fifth preset threshold to 3 and the sixth preset threshold to 1 Tb. The above is only an example of the fifth preset threshold and the sixth preset threshold, and the application does not limit the fifth preset threshold and the sixth preset threshold at all.

If the BBU determines whether the number of the first terminal devices is smaller than a fifth preset threshold, and/or whether the traffic volume of the first terminal devices is smaller than a sixth preset threshold, the BBU executes S803.

And S803, the BBU instructs the RRU to close the downlink subframes with the second preset number and the radio frequency channels with the third preset number.

The second preset quantity and the third preset quantity are determined according to the quantity of the first terminal equipment and the traffic of the first terminal equipment.

It should be noted that, the relationship between the number of the first terminal devices and the traffic of the first terminal devices and the second preset number may be as shown in fig. 9.

As shown in fig. 9, in the case that the number of the first terminal devices is 5 and the traffic of the first terminal devices is 5Tb, the BBU may set the second preset number to 1. In the case that the number of the first terminal devices is 4 and the traffic of the first terminal devices is 4Tb, the BBU may set the second preset number to 2. In the case that the number of the first terminal devices is 3 and the traffic of the first terminal devices is 3Tb, the BBU may set the second preset number to 3.

It should be noted that the above relationship between the number of the first terminal devices and the traffic of the first terminal devices and the third preset number can also be understood with reference to fig. 9.

Optionally, the BBU may also turn off a fourth predetermined number of power amplifiers in order to reduce the quiescent power consumption of the device (i.e., the power consumption resulting from leakage current when circuitry in the device is in an inactive state).

It should be noted that the fourth predetermined number may be understood by referring to the second predetermined number or the third predetermined number, and details are not described herein.

Optionally, when the BBU determines that the number of the first terminal devices is greater than or equal to a fifth preset threshold, and/or the traffic volume of the first terminal device is greater than or equal to a sixth preset threshold, the BBU may determine the number of the third terminal devices in a next detection period.

Illustratively, in scenario 3, the BBU may set the above detection period to 4 microseconds.

The technical scheme at least has the following beneficial effects: according to the device energy saving method provided by the application, the BBU firstly determines whether the first data meets at least one of the following conditions: and if not, determining whether the number of the first terminal equipment is less than a fifth preset threshold or not by the BBU, and if so, indicating to close the downlink subframes with the second preset number and indicating to close the radio frequency channels with the third preset number by the BBU, so that the energy-saving efficiency of the equipment is further improved, and the energy-saving effect of the equipment is further optimized.

It should be noted that fig. 4-8 illustrate specific implementation processes of device energy saving. Before the BBU receives first data from the RRU and judges whether the RRU starts an energy-saving state according to the first data, the RRU needs to determine the first data. With reference to fig. 4, as shown in fig. 10, before S401, a specific implementation process of determining the first data by the RRU may include the following S1001-S1008.

S1001, the BBU generates scheduling information and an identification list.

Wherein the scheduling information includes: time domain resource information of each fourth terminal device in the at least one fourth terminal device, and frequency domain resource information of each fourth terminal device.

The list of identifications includes: the device identifier of each fourth terminal device.

It should be noted that the fourth terminal device is any terminal device under the coverage of the target cell. The number of the fourth terminal devices may be the number of all terminal devices under the coverage of the target cell, and the number of the fourth terminal devices may also be the number of partial terminal devices under the coverage of the target cell.

S1002, the BBU sends scheduling information and an identification list to at least one RRU. Correspondingly, the RRU receives scheduling information and an identification list from the BBU.

It should be noted that the at least one RUU may be all the RRUs in the target cell, or may be a part of the RRUs in the target cell.

S1003, the RRU sends scheduling information and an identification list to the first terminal equipment. Correspondingly, the first terminal device receives the scheduling information and the identification list from the RRU.

It should be noted that the RRU may send the scheduling information to all the first terminal devices under the RRU, or may send the scheduling information to a part of the first terminal devices under the RRU.

S1004, the first terminal device determines whether its own identifier is located in the identifier list.

It should be noted that, only if the device identifier of the first terminal device is located in the identifier list, the first terminal device may analyze the scheduling information, and therefore, the first terminal device needs to determine whether its own identifier is located in the identifier list.

If the first terminal device determines that its own identifier is located in the identifier list, the first terminal device executes S1005.

S1005, the first terminal device parses the scheduling information, and obtains its own time domain resource information and frequency domain resource information.

It should be noted that, the specific implementation process of the above S1005 is as follows: the first terminal device analyzes the scheduling information to obtain time domain resource information of each fourth terminal device and frequency domain resource information of at least one fourth terminal device in at least one fourth terminal device included in the scheduling information, and determines time domain resource information and frequency domain resource information of the first terminal device from the time domain resource information of at least one fourth terminal device and the frequency domain resource information of at least one fourth terminal device.

And S1006, the first terminal equipment generates service data.

Wherein the service data comprises at least one of: the device identifier of the first terminal device, the signal strength of the first terminal device, the traffic of the first terminal device, and the service identifier list of the first terminal device.

And S1007, the first terminal device sends service data to the RRU according to the time domain resource information and the frequency domain resource information of the first terminal device included in the scheduling information. Correspondingly, the RRU receives service data from the first terminal device.

It should be noted that the time domain resource information and the frequency domain resource information may be used to indicate how the first terminal device sends the service data, and therefore, in a process that the first terminal device sends the service data to the RRU, the fourth terminal device needs to send the time domain resource information and the frequency domain resource information according to its own time domain resource information and frequency domain resource information.

S1008, the RRU generates first data according to the service data.

It should be noted that the specific implementation process of S1008 is as follows: and the RRU performs decoding processing on the service data, and then acquires the equipment identifier of the first terminal equipment, the signal strength of the first terminal equipment, the service volume of the first terminal equipment and the service identifier list of the first terminal equipment, which are included in the service data, from the decoded service data. And the RRU determines the number of the first terminal equipment according to the equipment identification of the first terminal equipment. The RRU determination comprises the following steps: and taking at least one item of data among the device identifier of the first terminal device, the signal strength of the first terminal device, the traffic of the first terminal device, the service identifier list of the first terminal device, the number of the first terminal devices and the data of the RRU identifier as first data.

The technical scheme at least brings the following beneficial effects: according to the equipment energy-saving method provided by the application, the BBU generates the scheduling information and the identification list, and sends the scheduling information and the identification list to the first terminal equipment through the RRU. After the first terminal device receives the scheduling information, the first terminal device determines whether its own device identifier is located in the identifier list, and if so, the first terminal device may parse the scheduling information and obtain its own time domain resource information and frequency domain resource information from the scheduling information. And the first terminal equipment generates service data and sends the service data to the RRU according to the time domain resource information and the frequency domain resource information. After the RRU receives the service data from the first terminal device, the RRU may generate the first data according to the service data, so as to provide data preparation for the subsequent BBU to determine whether the RRU is in the power saving state according to the first data.
