Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, in particular to a cell deactivation method, a cell deactivation system, an electronic device and a computer readable storage medium. BACKGROUND

[0002] In order to reduce the energy consumption of wireless networks, various energy-saving technologies have been proposed. Among them, the cell shutdown technology can be based on the tidal effect of the existing network business. When the business load of a cell is low, the cell is deactivated, and part of the hardware resources of the base station where the cell is located is turned off to achieve the purpose of energy saving. After the cell is deactivated, it no longer receives or transmits signals, and UEs cannot access the cell. Therefore, cell shutdown is generally applied to scenarios where multiple cells in the same area are simultaneously covered. When one cell is deactivated, UEs in the coverage area can access other cells to avoid access failure. When the business load in the coverage area increases, the relevant hardware resources can be remotely loaded through the device network management background to make the deactivated cell switch to the activated state and resume normal work.

[0003] In the prior art, the cell deactivation for the purpose of base station energy saving is mainly based on the size of the business load of the cell. When the business load of the cell is low, the cell is deactivated to reduce the energy consumption of the base station. When there are multiple cells with low business load in the same coverage area, some cells are configured as coverage layer cells and the other cells are configured as capacity layer cells based on a static configuration. In order to meet the signal coverage requirements of the area, only the capacity layer cells can be deactivated, and the coverage layer cells cannot be deactivated. In this way, even if the business load of the coverage layer cell is very low, the coverage layer cell cannot be deactivated, resulting in waste of energy consumption. The total energy consumption of all cells corresponding to the same coverage area cannot be minimized, and the energy-saving effect is not good. SUMMARY

[0054] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments and drawings described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0055] It should be noted that the terms "first", "second" and the like in the specification and claims of the present disclosure and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence; and in the case of no conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0056] The terminology used in the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting thereof. As used in the specification and appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0057] In the following description, the suffix used for an element such as "module", "part", or "unit" is merely for the convenience of describing the present disclosure, and has no specific meaning by itself. Thus, "module", "part", or "unit" can be used interchangeably.

[0058] With the deployment of 5G networks, the network scale is expanding, the demand for energy of various communication devices is increasing, and the energy consumption of communication networks is increasing. In addition, from 4G to 5G, mobile communication technology and products have changed, 5G base stations support larger bandwidth, more channel numbers, more complex air interface protocols, and device hardware processing capabilities are higher, and power consumption is also significantly increased compared with 4G base stations, which brings new challenges to wireless network energy saving.

[0059] To achieve the goal of energy saving, when the service load of a cell is low, the cell can be deactivated to reduce the energy consumption of the base station. When there are multiple cells with low service load in the same coverage area, some specific cells are deactivated based on a static configuration. However, the prior art only considers the service load of the cell itself when determining the deactivation of the cell, and does not consider the energy saving state and energy consumption of the adjacent cells. For example, if there are multiple cells in the same coverage area, and the service loads of the capacity layer cells and the coverage layer cells both meet the deactivation condition, the energy consumption of the capacity layer cells is small, and the energy consumption of the coverage layer cells is large. Deactivating the capacity layer cells will cause the cells with small energy consumption to be deactivated, while the cells with large energy consumption are in the activated state, resulting in large total energy consumption of the coverage area.

[0060] The technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above technical problems in the prior art will be described in detail below with specific embodiments. It can be understood that in the embodiments of the present application, the execution subject can execute part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also execute other operations or variations of various operations. In addition, each step can be executed in a different order as presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are executed. In addition, the following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0062] Step S101: determining a target neighbor cell corresponding to a target cell;

[0063] Step S102: acquiring an energy saving performance parameter of the target neighbor cell, and acquiring an energy saving state in which the target neighbor cell is located, the energy saving state comprising an active state or a deactivated state;

[0064] Step S103: determining whether to deactivate the target cell according to the energy saving performance parameter and the energy saving state of the target cell and the target neighbor cell;

[0065] Step S104: if yes, directly deactivating the target cell when there is a cell in the active state in the target neighbor cell; and,

[0066] Step S105: when there is no cell in the active state in the target neighbor cell, determining a neighbor cell to be activated, sending a message to switch to the active state to a network device of the neighbor cell to be activated, and deactivating the target cell.

[0067] The embodiment of the present disclosure determines the neighbor cell having the same signal coverage area as the target cell as the target neighbor cell, acquires the energy saving performance parameter of the target neighbor cell periodically based on the message interaction and cooperation of the target cell and the target neighbor cell, to dynamically track the energy efficiency or energy consumption change of the target neighbor cell, and to acquire the energy saving state of the target neighbor cell in real time; on this basis, judges whether the target cell can be deactivated based on the energy saving performance parameter and the energy saving state of the target neighbor cell; can make the energy saving state of the target cell dynamically match the energy saving performance parameter of the target neighbor cell, so as to keep the cell with larger energy consumption in the deactivated state to reduce the total energy consumption of the target area; at the same time, when all the target neighbor cells in the target area are in the deactivated state at the target time, the target cell sends a message to the neighbor cell to be activated before being deactivated, so that the neighbor cell to be activated is switched to the active state, so as to ensure that there is at least one cell in the active state in the target coverage area to meet the signal coverage requirement.

[0068] The network device of the target cell and the network device of the target neighbor cell can be a base station, an access network device, an operation and maintenance device / network management device, etc., the cells in the target cell and the target neighbor cell can be under the same base station, or under different base stations, and when under the same base station, the communication process of the target cell and the target neighbor cell is the interaction within the base station device. In the description of the embodiment of the present disclosure, the actions performed by the target cell and the target neighbor cell are performed by the network device of the target cell and the network device of the target neighbor cell.

[0069] The network configuration of the target cell and the target neighbor cell is as follows Figure 2As shown, the target region is any energy-saving region defined in the network, including a plurality of cells; the target cell is any cell in the target region; and the target neighbor cell includes one or more neighboring cells having the same signal coverage area as the target cell.

[0070] Further, the determination of the target neighbor cell corresponding to the target cell includes:

[0071] determining the target neighbor cell corresponding to the target cell according to any one of the operating parameter data of each cell in the target region, the measurement report of the target cell, and the handover data;

[0072] wherein the determination of the target neighbor cell corresponding to the target cell according to the operating parameter data of each cell in the target region includes:

[0073] determining the cell distance according to the latitude and longitude of the target cell and each neighboring cell in the target region, and regarding a neighboring cell as the target neighbor cell of the target cell if the distance between the neighboring cell and the target cell is less than a preset distance threshold and the difference between the azimuth angles of the two cells is less than a preset angle threshold;

[0074] the determination of the target neighbor cell corresponding to the target cell according to the measurement report of the target cell includes:

[0075] obtaining the measurement report of the terminal, which carries the identification and signal strength measurement value of the target cell and the neighboring cell;

[0076] regarding a measurement report as the target measurement report if the difference between the signal strength measurement values of the target cell and the first neighboring cell carried in the measurement report is less than a preset difference value, wherein the first neighboring cell is any neighboring cell in the target region;

[0077] regarding the first neighboring cell as the target neighbor cell of the target cell if the number of target measurement reports accounts for more than a preset ratio in the measurement reports obtained by the target cell within a preset time length;

[0078] the determination of the target neighbor cell corresponding to the target cell according to the handover data includes:

[0079] counting the handover data of the target cell within a preset first historical time, which includes the number of terminal handovers under the target cell and the corresponding target cells of the handovers;

[0080] regarding a neighboring cell as the target neighbor cell of the target cell if the number of terminal handovers to the neighboring cell accounts for more than a preset percentage in the terminal handovers of the target cell within the preset first historical time, wherein the number of terminal handovers to the neighboring cell includes the sum of the number of terminal handovers from the target cell to the neighboring cell and the number of terminal handovers from the neighboring cell to the target cell.

[0081] Among them, the distance threshold, angle threshold, preset difference, preset duration, preset ratio, preset first historical time, and preset percentage can all be set based on historical experience and selected according to actual conditions. The target neighboring cells corresponding to the target cell can be preset on the base station side where the target cell is located, or they can be determined based on any one of the following: the operating parameters of each cell in the target area, the measurement report of the target cell, and the handover data. By determining the target neighboring cells, the target cell can identify adjacent cells with the same signal coverage area as the target cell. Then, based on the message interaction and coordination between the target cell and the target neighboring cells, it can be determined whether the target cell can be deactivated, so that the total energy consumption of multiple cells in the coverage area of ​​the target cell is minimized.

[0082] Furthermore, obtaining the energy-saving performance parameters of the target neighboring cells for the target cell includes:

[0083] Send a first message to the network device of the target neighboring cell at a preset period to obtain the energy-saving performance parameters of the target neighboring cell. The first message carries the target cell identifier and the energy-saving performance parameter type identifier. The energy-saving performance parameter type identifier is used to indicate the energy-saving performance parameter type. The energy-saving performance parameter type includes at least one of energy efficiency, energy consumption, energy efficiency prediction value and energy consumption prediction value.

[0084] The system receives a second message sent by the network device of the target neighboring cell to the network device of the target cell at a preset period. This second message carries the target neighboring cell identifier and the energy-saving performance parameter value of the target neighboring cell. The energy-saving performance parameter value corresponds one-to-one with the energy-saving performance parameter type identifier carried in the first message.

[0085] Update the energy efficiency performance parameter values ​​of the target neighboring cell in the storage.

[0086] Energy-saving performance parameters include at least one of the following: energy efficiency, energy consumption, predicted energy efficiency, and predicted energy consumption.

[0087] Energy efficiency parameters are used to reflect the energy usage efficiency of the base station where the cell is located in the current period, and are defined as the ratio of effective output to energy consumption in the current period. Effective output is used to reflect the data transmission performance or signal coverage performance of the cell, and can be defined in different ways. For example, effective output can be defined as a combination of one or more parameters such as the cell's traffic volume, coverage area, coverage area signal strength, and service transmission performance (including transmission rate, transmission delay, etc.).

[0088] Energy consumption parameters are used to reflect the power consumption of the base station where the cell is located in the current period, and can be defined as the average power consumption in a predetermined period; energy consumption parameters can be statistically analyzed by the target neighboring cells according to a predetermined period;

[0089] The energy efficiency prediction value is used to reflect the energy use efficiency of the base station where the cell is located in a future period; the future period is the next period after the current period; the energy efficiency prediction value can be predicted by the target cell and the target neighbor cell; specifically,

[0090] determined according to a plurality of energy efficiency parameters in a preset second historical time; wherein the preset second historical time includes a plurality of predetermined periods before the current period, and one predetermined period corresponds to one energy efficiency parameter; the plurality of energy efficiency parameters in the preset second historical time are taken as sample values, input into a prediction model, and a trained prediction model is obtained; the preset future period is input into the trained prediction model, and a corresponding energy efficiency prediction value is obtained; optionally, the prediction model can adopt a time series prediction model, such as PROPHET, ARIMA, LSTM, neural network, etc.

[0091] The energy consumption prediction value is used to reflect the power consumption of the base station where the cell is located in a future period; the future period is the next period after the current period; the energy consumption prediction value can be predicted by the target cell and the target neighbor cell, and the prediction method is the same as that of the energy efficiency prediction value;

[0092] It should be noted that the energy efficiency parameter and the energy consumption parameter can be counted by the target cell and the target neighbor cell according to a predetermined period; one predetermined period can be an activation period or a deactivation period; wherein if the time length of the cell in the activation state in a certain predetermined period accounts for more than a preset ratio, the predetermined period is an activation period; otherwise, the predetermined period is a deactivation period.

[0093] The target cell acquires the second message according to a preset period, and periodically updates the stored energy saving performance parameter value; that is, when the target cell receives a new second message, the energy saving performance parameter value in the new second message is used to replace the previously stored energy saving performance parameter value.

[0094] The target cell can dynamically track the changes of the energy efficiency or energy consumption of the target neighbor cell by periodically acquiring the energy saving performance parameters of the target neighbor cell, so as to accurately determine whether the target cell can be deactivated based on the energy efficiency or energy consumption parameters of the target neighbor cell, so that the energy saving state of the target cell dynamically matches the energy saving performance parameters of the target neighbor cell, and the total energy consumption of the coverage area where the target cell is located is minimized.

[0095] Further, the method further comprises:

[0096] The energy saving performance parameter type identifier is represented by a bit map, and different energy saving performance parameter types are represented according to different bit numbers of the bit map.

[0097] The energy-saving performance parameter type identifier can be represented as a bit map; if the energy-saving performance parameter includes energy efficiency, the x1th bit in the bit map can represent the energy efficiency parameter; if the energy-saving performance parameter includes energy consumption, the x2th bit in the bit map can represent the energy consumption parameter; if the energy-saving performance parameter includes an energy efficiency prediction value, the x3th bit in the bit map can represent the energy efficiency prediction value parameter; if the energy-saving performance parameter includes an energy consumption prediction value, the x4th bit in the bit map can represent the energy consumption prediction value parameter.

[0098] If the value of a bit position in the bit map is 1, it indicates that the energy-saving performance parameter value of the type corresponding to the bit position needs to be fed back; if the value of a bit position in the bit map is 0, it indicates that the energy-saving performance parameter value of the type corresponding to the bit position does not need to be fed back; as an example, if the bit value of the x1th bit in the bit map is 1, it indicates that the target neighbor cell needs to feed back the energy efficiency parameter to the target cell; if the bit value of the x1th bit in the bit map is 0, it indicates that the target neighbor cell does not need to feed back the energy efficiency parameter to the target cell.

[0099] Optionally, the first message can be an existing message or a newly added message.

[0100] Taking the 5G system as an example, the first message can be obtained by adding a new information element (IE) to the 5G system Xn interface message RESOURCE STATUS REQUEST;

[0101] The RESOURCE STATUS REQUEST message is sent by base station 1 to base station 2, and is used to initiate the measurement specified by the parameters in the message.

[0102] The first message adds the following information element (IE) to the RESOURCE STATUS REQUEST message:

[0103] Table 1: Structure of the added information element of the first message

[0104]

[0105] It should be noted that the first message can include at least one of the energy efficiency, energy consumption, energy efficiency prediction value, and energy consumption prediction value; accordingly, the information element Report Characteristics of the first message can include at least one of the x1th, x2th, x3th, and x4th bits, i.e., it does not necessarily include all four bits.

[0106] If the X1th bit in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes an energy efficiency value; if the X2th bit in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes an energy consumption value; if the X3th bit in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes an energy efficiency prediction value; if the X4th bit in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes an energy consumption prediction value;

[0107] Optionally, the second message can be an existing message or a newly added message.

[0108] Taking the 5G system as an example, the second message can be obtained by adding a new information element (IE) to the RESOURCE STATUS UPDATE message of the Xn interface of the 5G system;

[0109] The RESOURCE STATUS UPDATE message is sent by the base station 2 to the base station 1 as a response to the RESOURCE STATUS REQUEST message, and is used to report the measurement result of the base station 2.

[0110] The second message adds the following information element (IE) to the RESOURCE STATUS UPDATE message:

[0111] Table 2: Structure of the added information element of the second message

[0112]

[0113] It should be noted that at least one of the energy efficiency, the energy consumption, the predicted energy efficiency, and the predicted energy consumption can be included in the information element of the second message, that is, all four bits are not necessarily included.

[0114] The bit map can better realize the interaction of the energy saving performance parameters between cells and realize dynamic tracking of the change of the energy efficiency or the energy consumption of the target neighbor cell.

[0115] Further, the obtaining of the energy saving state in which the target neighbor cell is located includes:

[0116] The network device receiving the third message or the fourth message sent by the target neighbor cell when the energy saving state of the target neighbor cell changes, the third message being used to indicate that the target neighbor cell is in the deactivated state after the change, and the fourth message being used to indicate that the target neighbor cell is in the activated state after the change.

[0117] updating the energy saving state of the target neighbor cell to the cell deactivation state according to the third message; or

[0118] updating the energy saving state of the target neighbor cell to the cell activation state according to the fourth message.

[0119] The third message carries information such as target neighbor cell identifier and cell deactivation state indication; in response, the target cell updates the energy saving state of the target neighbor cell to the cell deactivation state after receiving the third message; the fourth message carries information such as target neighbor cell identifier and cell activation state indication; in response, the target cell updates the energy saving state of the target neighbor cell to the cell activation state after receiving the fourth message.

[0120] When the cell undergoes energy saving state conversion, including conversion from the activation state to the deactivation state or conversion from the deactivation state to the activation state, the third message or the fourth message is sent to other neighbor cells existing in the same signal coverage area; in this way, the energy saving states of other cells can be learned in real time through message interaction among multiple cells in the same coverage area, so as to determine whether the cell can be deactivated based on the energy saving state of the neighbor cell, which can not only guarantee that at least one cell in the same coverage area is in the activation state to meet the signal coverage requirement, but also enable a cell with smaller energy consumption to remain in the deactivation state to reduce the total energy consumption of the coverage area.

[0121] Further, the determination of whether to deactivate the target cell according to the energy saving performance parameters and the energy saving state of the target cell and the target neighbor cell comprises:

[0122] determining whether the service load of the target cell at the target time is less than a preset load threshold;

[0123] if yes, further determining whether the target cell and the target neighbor cell satisfy a preset condition;

[0124] if yes, determining to deactivate the target cell, otherwise, not allowing to deactivate the target cell;

[0125] The preset condition is satisfied when the first preset condition or the second preset condition is satisfied; the first preset condition is that the energy saving states of all target neighbor cells at the target time are in the deactivation state, and the target energy efficiency value / target energy efficiency prediction value of the target cell is less than the target energy efficiency value / target energy efficiency prediction value of any target neighbor cell or the target energy consumption value / target energy consumption prediction value of the target cell is greater than the target energy consumption value / target energy consumption prediction value of any target neighbor cell, wherein the target energy efficiency value, the target energy consumption value, the target energy efficiency prediction value and the target energy consumption prediction value are determined according to the energy saving performance parameters; the second preset condition is that at least one target neighbor cell is in the activation state at the target time.

[0126] If the service load of the target cell at the target moment is less than the preset load threshold, the target cell further judges whether a preset condition is met; if the target cell meets the first preset condition or the second preset condition, the target cell is deactivated; otherwise, the target cell is not allowed to be deactivated.

[0127] The service load at the target moment can be defined as an average value of service loads in a preset time period before the target moment, or a predicted value of the service load in a preset time period after the target moment; both of them can be determined according to a plurality of service load statistics values in the preset time period before the target moment; the average value of the service load is an average value of the plurality of service load statistics values in the preset time period before the target moment; the predicted value of the service load can take the plurality of service load statistics values in the preset time period before the target moment as samples, input a preset prediction model for model training, and then obtain the predicted value of the service load according to the trained prediction model.

[0128] The first preset condition and the second preset condition are preset cell deactivation conditions.

[0129] The first preset condition is:

[0130] All target neighbor cells are in the deactivation state at the target moment, and the target energy efficiency value / target energy efficiency predicted value of the target cell is less than the target energy efficiency value / target energy efficiency predicted value of any target neighbor cell, or the target energy consumption value / target energy consumption predicted value of the target cell is greater than the target energy consumption value / target energy consumption predicted value of any target neighbor cell; that is, the target cell is not the cell with the lowest energy consumption or the highest energy efficiency in the target area.

[0131] The second preset condition is:

[0132] At least one target neighbor cell is in the activation state at the target moment.

[0133] The target energy efficiency value, the target energy consumption value, the target energy efficiency predicted value, and the target energy consumption predicted value are the energy saving performance parameter values corresponding to the last activation period before the target moment.

[0134] The energy saving state of the target neighbor cell at the target moment is determined according to the last message sent by the target neighbor cell and received by the target cell before the target moment; specifically,

[0135] If the last message sent by the target neighbor cell and received by the target cell before the target moment is the third message, the energy saving state of the target neighbor cell at the target moment is the deactivation state.

[0136] If the last message sent by the target neighbor cell and received by the target cell before the target moment is the fourth message, the energy saving state of the target neighbor cell at the target moment is the activation state.

[0137] The present disclosure considers the energy-saving state of the target neighbor cell, the energy-saving performance parameters of the target cell itself and the target neighbor cell when determining whether the target cell can be deactivated in addition to the service load condition. When all target neighbor cells in the target area are in the deactivation state, the energy consumption of the target cell and the target neighbor cell is compared, so that the cell with smaller energy consumption is in the activation state and the cell with larger energy consumption is in the deactivation state, which can not only guarantee that there is at least one cell in the activation state in the target coverage area to meet the signal coverage requirement, but also reduce the total energy consumption of the target area. When at least one target neighbor cell in the target area is in the activation state, the target cell can be deactivated to reduce the energy consumption of the target area.

[0138] Further, the determination of the to-be-activated neighbor cell comprises:

[0139] The cell with the maximum target energy efficiency value / target energy efficiency prediction value or the minimum target energy consumption value / target energy consumption prediction value among all the deactivated neighbor cells is determined as the to-be-activated neighbor cell.

[0140] The to-be-activated neighbor cell is the cell with the maximum target energy efficiency value / target energy efficiency prediction value or the minimum target energy consumption value / target energy consumption prediction value among all the deactivated neighbor cells; the deactivated neighbor cell is the target neighbor cell in the deactivation state at the target time; the fifth message carries the target cell identifier, the cell activation indication and other information;

[0141] It should be noted that if all target neighbor cells in the target area are in the deactivation state at the target time, the target cell sends the fifth message to the to-be-activated neighbor cell and then performs the deactivation operation to convert to the deactivation state. In addition, after receiving the fifth message, the to-be-activated neighbor cell performs the cell activation operation to convert to the activation state and sends the fourth message to the target cell.

[0142] When all target neighbor cells in the target area are in the deactivation state at the target time, the target cell sends the fifth message to the to-be-activated neighbor cell before being deactivated, so that the to-be-activated neighbor cell converts to the activation state. In this way, it can be guaranteed that there is at least one cell in the activation state in the target area to meet the signal coverage requirement. At the same time, by determining the target neighbor cell with smaller energy consumption as the to-be-activated neighbor cell, the energy consumption of the target area after the to-be-activated neighbor cell is activated can be smaller.

[0143] In order to more clearly describe the technical solutions of the present disclosure, as shown in Figure 3 The second embodiment of the present disclosure also provides a cell deactivation method, and the specific process comprises S1-S8:

[0144] The network configuration of the target area is as shown in Figure 2As shown, the target area is any designated energy-saving area in the network, including multiple cells; the target cell is any cell in the target area; the target neighbor area includes one or more neighboring cells that have the same signal coverage area as the target cell; it should be noted that the execution order between steps S2-S3, step S4, and step S5 is not limited and can be executed in any order or simultaneously.

[0145] S1, the target cell determines the corresponding target neighbor area;

[0146] The target neighbor area corresponding to the target cell can be pre-set on the base station side where the target cell is located, or can be determined according to any one of the operating parameters of each cell in the target area, the measurement report of the target cell, and the handover data.

[0147] The target cell obtains the operating parameter data of each neighboring cell in the target area, including the latitude and longitude of the base station where the cell is located, and the azimuth angle of the antenna; the cell spacing is determined according to the latitude and longitude of the target cell and the neighboring cell, if the spacing between a certain neighboring cell and the target cell is less than a pre-set distance threshold, and the difference between the azimuth angles of the two cells is less than a pre-set angle threshold, then the neighboring cell is considered as the target neighbor area corresponding to the target cell.

[0148] The target cell obtains the measurement report of the terminal, which carries the identification and signal strength measurement value of the target cell and the neighboring cell; if the difference between the signal strength measurement values of the target cell and the first neighboring cell carried in a certain measurement report is less than a pre-set difference value, then the measurement report is determined as a target measurement report; wherein the first neighboring cell is any neighboring cell in the target area; if the number of target measurement reports accounts for more than a pre-set ratio in the measurement reports obtained by the target cell within a pre-set time, then the first neighboring cell is determined as the target neighbor area of the target cell.

[0149] The target cell statistics handover data within a pre-set first historical time, including the number of terminal handovers under the target cell and the corresponding handover target cell; if the number of terminal handovers of a certain neighboring cell under the target cell within the pre-set first historical time accounts for more than a pre-set percentage, then the neighboring cell is determined as the target neighbor area corresponding to the target cell; wherein the number of terminal handovers to a certain neighboring cell includes the sum of the number of terminals under the target cell that are cut out to the neighboring cell and the number of terminals that are cut in from the neighboring cell to the target cell.

[0150] In this embodiment, the target cell can determine the neighboring cell that has the same signal coverage area as the target cell by determining the target neighbor area, and then determine whether the target cell can be deactivated based on the message interaction and cooperation between the target cell and the target neighbor area, so that the total energy consumption of multiple cells in the coverage area where the target cell is located is minimized.

[0151] S2, the target cell sends a first message to the target neighbor cell according to a preset period, for obtaining the energy saving performance parameter of the target neighbor cell;

[0152] The first message carries the target cell identifier, the energy saving performance parameter type identifier and the like information; wherein, the energy saving performance parameter type identifier is used for indicating the energy saving performance parameter type; as an example, the energy saving performance parameter type identifier can be represented as a bit map; if the energy saving performance parameter includes the energy efficiency, the x1th bit in the bit map can be used to represent the energy efficiency parameter; if the energy saving performance parameter includes the energy consumption, the x2th bit in the bit map can be used to represent the energy consumption parameter; if the energy saving performance parameter includes the energy efficiency prediction value, the x3th bit in the bit map can be used to represent the energy efficiency prediction value parameter; if the energy saving performance parameter includes the energy consumption prediction value, the x4th bit in the bit map can be used to represent the energy consumption prediction value parameter;

[0153] If the value of a bit position in the bit map is 1, it indicates that the energy saving performance parameter value of the type corresponding to the bit position needs to be fed back; if the value of a bit position in the bit map is 0, it indicates that the energy saving performance parameter value of the type corresponding to the bit position does not need to be fed back; as an example, if the bit value of the x1th bit in the bit map is 1, it indicates that the target neighbor cell needs to feed back the energy efficiency parameter to the target cell; if the bit value of the x1th bit in the bit map is 0, it indicates that the target neighbor cell does not need to feed back the energy efficiency parameter to the target cell;

[0154] Optionally, the first message can be an existing message or a newly added message;

[0155] Taking the 5G system as an example, the first message can be obtained by adding a new information element (IE) to the RESOURCE STATUS REQUEST message of the 5G system Xn interface;

[0156] The RESOURCE STATUS REQUEST message is sent by base station 1 to base station 2, for initiating the measurement specified by the parameters in the message;

[0157] The first message adds the following information element (IE) to the RESOURCE STATUS REQUEST message:

[0158] Table 1: Structure of the added information element of the first message

[0159]

[0160]

[0161] It should be noted that at least one of the energy efficiency, energy consumption, energy efficiency prediction value, and energy consumption prediction value can be included in the first message; correspondingly, at least one of X1, X2, X3, and X4 can be included in the information element Report Characteristics of the first message, i.e., all four bits are not necessarily included;

[0162] The energy saving performance parameter includes at least one of the energy efficiency, energy consumption, energy efficiency prediction value, and energy consumption prediction value;

[0163] The energy efficiency parameter is used to reflect the energy use efficiency of the base station where the cell is located in the current period, and is defined as the ratio of the effective output amount to the energy consumption in the current period; the effective output amount is used to reflect the data transmission performance or signal coverage performance of the cell, and different definition methods can be adopted; for example, the effective output amount can be defined as one or a combination of a plurality of parameters such as the traffic volume, the coverage area, the coverage area signal strength, and the service transmission performance (including transmission rate, transmission delay, etc.) of the cell;

[0164] The energy consumption parameter is used to reflect the power consumption of the base station where the cell is located in the current period, and can be defined as the average power consumption in a predetermined period; the energy consumption parameter can be counted by the target neighbor cell in a predetermined period;

[0165] The energy efficiency prediction value is used to reflect the energy use efficiency of the base station where the cell is located in the future period; the future period is the next period after the current period; the energy efficiency prediction value can be predicted by the target cell and the target neighbor cell; specifically,

[0166] determined according to a plurality of energy efficiency parameters in a preset second historical time; wherein the preset second historical time includes a plurality of predetermined periods before the current period, and one predetermined period corresponds to one energy efficiency parameter; the plurality of energy efficiency parameters in the preset second historical time are taken as sample values, input into a prediction model, and a trained prediction model is obtained; the preset future period is input into the trained prediction model, and a corresponding energy efficiency prediction value is obtained; optionally, the prediction model can adopt a time series prediction model such as PROPHET, ARIMA, LSTM, neural network, etc.

[0167] The energy consumption prediction value is used to reflect the power consumption of the base station where the cell is located in the future period; the future period is the next period after the current period; the energy consumption prediction value can be predicted by the target cell and the target neighbor cell, and the prediction method is the same as that of the energy efficiency prediction value;

[0168] It should be noted that the energy efficiency parameter and the energy consumption parameter can be counted by the target cell and the target neighbor cell in a predetermined period; one predetermined period can be an activation period or a deactivation period; wherein if the time length of the cell in the activation state in a certain predetermined period accounts for more than a preset ratio, the predetermined period is an activation period; otherwise, the predetermined period is a deactivation period.

[0169] In the method, the target cell periodically acquires the energy saving performance parameter of the target neighbor cell, dynamically tracks the change of the energy efficiency or energy consumption of the target neighbor cell, and accurately determines whether the target cell can be deactivated based on the energy efficiency or energy consumption parameter of the target neighbor cell, so that the energy saving state of the target cell dynamically matches the energy saving performance parameter of the target neighbor cell, and the total energy consumption of the coverage area where the target cell is located is minimized.

[0170] S3, the target neighbor cell sends a second message to the target cell according to a preset period, and the second message carries the energy saving performance parameter value of the target neighbor cell.

[0171] The second message carries the target neighbor cell identifier, the energy saving performance parameter value of the target neighbor cell, and the like. The energy saving performance parameter value corresponds to the energy saving performance parameter type identifier carried in the first message. For example, if the X1th bit value in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes the energy efficiency value; if the X2th bit value in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes the energy consumption value; if the X3th bit value in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes the energy efficiency prediction value; and if the X4th bit value in the bit map corresponding to the energy saving parameter type identifier is 1, the energy saving performance parameter value includes the energy consumption prediction value.

[0172] Optionally, the second message can be an existing message or a newly added message.

[0173] Taking the 5G system as an example, the second message can be obtained by adding a new information element (IE) to the RESOURCE STATUS UPDATE message of the Xn interface of the 5G system.

[0174] The RESOURCE STATUS UPDATE message is a response to the RESOURCE STATUS REQUEST message, and is sent by the base station 2 to the base station 1 to report the measurement result of the base station 2.

[0175] The second message adds the following information element (IE) to the RESOURCE STATUS UPDATE message:

[0176] Table 2: Structure of the added information element of the second message

[0177]

[0178] It should be noted that at least one of the energy efficiency, energy consumption, predicted energy efficiency, and predicted energy consumption can be included in the information element of the second message, i.e., not all of the four bits are necessarily included;

[0179] It should be noted that the target cell acquires the second message at a preset period and periodically updates the stored energy saving performance parameter value; that is, when the target cell receives a new second message, the energy saving performance parameter value in the new second message is used to replace the previously stored energy saving performance parameter value;

[0180] S4, at the first time, the target cell receives the third message sent by the target neighbor cell, for indicating that the target neighbor cell is in the deactivation state;

[0181] The first time is a historical time before the target time; the first time is the time when the target neighbor cell is switched from the activation state to the deactivation state;

[0182] The third message carries the target neighbor cell identifier, the cell deactivation state indication and other information;

[0183] In response, the target cell updates the energy saving state of the target neighbor cell to the cell deactivation state after receiving the third message;

[0184] S5, at the second time, the target cell receives the fourth message sent by the target neighbor cell, for indicating that the target neighbor cell is in the activation state;

[0185] The second time is a historical time before the target time; the second time is the time when the target neighbor cell is switched from the deactivation state to the activation state;

[0186] The fourth message carries the target neighbor cell identifier, the cell activation state indication and other information;

[0187] In response, the target cell updates the energy saving state of the target neighbor cell to the cell activation state after receiving the fourth message;

[0188] In this embodiment, when the cell is switched from the activation state to the deactivation state or from the deactivation state to the activation state, the third message or the fourth message is sent to other neighbor cells in the same signal coverage area; in this way, the energy saving states of other cells can be learned in real time through message interaction between multiple cells in the same coverage area, so as to determine whether the cell can be deactivated based on the energy saving state of the neighbor cell, which can ensure that at least one cell in the same coverage area is in the activation state to meet the signal coverage requirement, and can also keep the cell with smaller energy consumption in the deactivation state to reduce the total energy consumption of the coverage area;

[0189] S6, determining, by the target cell, whether to deactivate the target cell at the target moment according to the energy saving performance parameter and the energy saving state;

[0190] If the service load of the target cell at the target moment is less than a preset load threshold, the target cell further determines whether a preset condition is met; if the target cell meets a first preset condition or a second preset condition, the target cell is deactivated; otherwise, the target cell is not allowed to be deactivated;

[0191] The service load at the target moment can be defined as an average value of service loads in a preset time period before the target moment, or a predicted value of the service load in a preset time period after the target moment; both of them can be determined according to a plurality of service load statistics values in the preset time period before the target moment; the average value of the service load is an average value of the plurality of service load statistics values in the preset time period before the target moment; the predicted value of the service load can take the plurality of service load statistics values in the preset time period before the target moment as samples, input a preset prediction model for model training, and then obtain the predicted value of the service load according to the trained prediction model;

[0192] The first preset condition and the second preset condition are preset cell deactivation conditions;

[0193] The first preset condition is:

[0194] All target neighbor cells have a deactivation state at the target moment, and the target energy efficiency value / target energy efficiency predicted value of the target cell is less than the target energy efficiency value / target energy efficiency predicted value of any target neighbor cell or the target energy consumption value / target energy consumption predicted value of the target cell is greater than the target energy consumption value / target energy consumption predicted value of any target neighbor cell;

[0195] The second preset condition is:

[0196] At least one target neighbor cell has an activation state at the target moment;

[0197] The target energy efficiency value, the target energy consumption value, the target energy efficiency predicted value, and the target energy consumption predicted value are energy saving performance parameter values corresponding to the last activation period before the target moment;

[0198] The energy saving state of the target neighbor cell at the target moment is determined according to the last message sent by the target neighbor cell and received by the target cell before the target moment; specifically,

[0199] If the last message sent by the target neighbor cell and received by the target cell before the target moment is the third message, the energy saving state of the target neighbor cell at the target moment is a deactivation state;

[0200] If the target cell receives the last message sent by the target neighbor cell before the target time as the fourth message, the energy saving state of the target neighbor cell at the target time is the active state;

[0201] In the method, in addition to the service load, the energy saving state of the target neighbor cell, and the energy saving performance parameters of the target cell and the target neighbor cell are considered when determining whether the target cell can be deactivated. When all the target neighbor cells in the target area are in the deactivated state, the energy consumption of the target cell and the target neighbor cell is compared, so that the cell with smaller energy consumption is in the active state, and the cell with larger energy consumption is in the deactivated state, which can not only guarantee that at least one cell in the target coverage area is in the active state to meet the signal coverage requirement, but also reduce the total energy consumption of the target area. When at least one target neighbor cell in the target area is in the active state, the target cell can be deactivated to reduce the energy consumption of the target area.

[0202] The energy saving state of the cell:

[0203] The energy saving state of the cell includes the active state and the deactivated state.

[0204] When the cell is in the deactivated state, the energy consumption of the base station can be reduced, for example, by turning off part of the hardware resources to reduce the energy consumption of the base station device where the cell is located. When the cell is in the deactivated state, the terminal cannot access the cell.

[0205] When the cell is in the active state, the cell can normally transmit and receive signals, for example, the turned-off hardware resources can be turned on to restore normal operation, and the terminal can access the cell.

[0206] It should be noted that the conversion process of the cell from the deactivated state to the active state can be triggered by the adjacent cell, the base station operation and maintenance device / network management device, or by the timing wake-up mode. Specifically,

[0207] The adjacent cell sends an activation instruction message to the energy saving cell in the deactivated state, and the energy saving cell converts to the active state after receiving the message.

[0208] The base station operation and maintenance device / network management device sends an activation instruction message to the energy saving cell in the deactivated state, and the energy saving cell converts to the active state after receiving the message.

[0209] The base station side where the cell is located is pre-set with a deactivation duration, and when the duration of the energy saving cell in the deactivated state reaches the deactivation duration, the energy saving cell automatically converts to the active state.

[0210] The conversion process of the cell from the active state to the deactivated state can be triggered by the base station where the cell is located, the base station operation and maintenance device / network management device, other third-party energy saving control platform, or by the timing wake-up mode. Specifically,

[0211] The base station where the cell in the active state is located judges according to preset cell deactivation conditions, and when it is determined that the preset cell deactivation conditions are met, the base station is switched to the deactivated state;

[0212] The base station operation and maintenance equipment / network management equipment or other third-party energy saving control platform sends a cell deactivation indication message to the cell in the active state, and after the cell receives the message, the cell is switched to the deactivated state;

[0213] The base station side where the cell is located is preset with a deactivation period, at the start time of the deactivation period, the cell is automatically switched to the deactivated state, and at the end time of the deactivation period, the cell is restored to the active state;

[0214] The embodiment does not limit the triggering mode of cell activation and deactivation, and any of the above modes can be used for triggering;

[0215] S7, if all target neighbor cells in the target area are in the deactivated state at the target time, before the target cell is deactivated, a fifth message is sent to the to-be-activated neighbor cell, for instructing the to-be-activated neighbor cell to be switched from the deactivated state to the active state; the fifth message is a message for switching to the active state.

[0216] The to-be-activated neighbor cell is a cell with the maximum target energy efficiency value / target energy efficiency prediction value or the minimum target energy consumption value / target energy consumption prediction value among all deactivated neighbor cells; wherein the deactivated neighbor cell is a target neighbor cell in the energy saving state of the deactivated state at the target time;

[0217] The fifth message carries the target cell identifier, cell activation indication and other information;

[0218] It should be noted that after the to-be-activated neighbor cell receives the fifth message, the cell activation operation is performed, so that the to-be-activated neighbor cell is switched to the active state, and the fourth message is sent to the target cell; (as described above)

[0219] In the embodiment, when all target neighbor cells in the target area are in the deactivated state at the target time, the target cell sends a fifth message to the to-be-activated neighbor cell before the target cell is deactivated, so that the to-be-activated neighbor cell is switched to the active state; in this way, at least one cell in the active state in the target area can be guaranteed, and the signal coverage requirement can be met; at the same time, by determining the target neighbor cell with smaller energy consumption as the to-be-activated neighbor cell, the energy consumption of the target area can be smaller after the to-be-activated neighbor cell is activated;

[0220] S8, after the target cell sends the fifth message to the to-be-activated neighbor cell, the deactivation operation is performed, and the target cell is switched to the deactivated state.

[0221] The embodiment of the present disclosure determines a neighboring cell with the same signal coverage area as the target cell as a target neighboring cell, periodically acquires energy-saving performance parameters of the target neighboring cell based on message interaction and cooperation between the target cell and the target neighboring cell, dynamically tracks changes in energy efficiency or energy consumption of the target neighboring cell, and learns the energy-saving state of the target neighboring cell in real time; on this basis, based on the energy-saving performance parameters and the energy-saving state of the target neighboring cell, it is determined whether the target cell can be deactivated; the energy-saving state of the target cell can be dynamically matched to the energy-saving performance parameters of the target neighboring cell, so that the cell with higher energy consumption remains in a deactivated state to reduce the total energy consumption of the target area; at the same time, when all target neighboring cells in the target area are in a deactivated state at a target time, the target cell sends a fifth message to the to-be-activated neighboring cell before being deactivated, so that the to-be-activated neighboring cell is switched to an activated state, so that at least one cell in an activated state exists in the target coverage area to meet the signal coverage requirement.

[0238] If the number of terminal handovers to a certain neighboring cell under the target cell accounts for more than a preset percentage within the preset first historical time, the neighboring cell is determined as the target neighbor cell corresponding to the target cell. The number of terminal handovers to a certain neighboring cell includes the sum of the number of terminals handed out from the target cell to the neighboring cell and the number of terminals handed in from the neighboring cell to the target cell.
