[0051] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] With the development of communication technology and the need for energy conservation and emission reduction, the energy efficiency of mobile communication base stations has gradually attracted people's attention. In particular, the power consumption of the fifth generation mobile communication technology (5G) base stations has become a major problem for operators. Research on reducing power consumption of base stations has also received more and more attention.

[0053] At present, there are various ways to save energy in mobile communication base stations. For example, in idle periods with less user traffic and in areas with less traffic, the base stations are dynamically reduced in terms of working hours and user resource allocation, and redundant resources are shut down to achieve energy saving and consumption reduction. The measures taken include channel shutdown, symbol shutdown, deep sleep, etc.

[0054] However, the current research on reducing power consumption of base stations is still focused on single-station / single-frequency equipment, which has achieved some significant results in individual energy saving and power reduction. However, the research on designing base station collaborative energy saving is still relatively blank.

[0055] Based on this, the embodiment of the present application provides an energy-saving control method for a communication base station, which is applied to a device. The function implemented by the method can be implemented by calling a program code by a processor in the device. Of course, the program code can be stored in a computer storage medium. It can be seen that the device at least includes a processor and a storage medium. As an example, the device can be a mobile phone, a computer, a terminal, an information transceiver device, a tablet device, a personal digital assistant, etc.

[0056] Figure 1 A schematic diagram of a communication base station energy saving control method flow is provided for an embodiment of the present application; Figure 1 As shown, the method includes:

[0057] Step 101: determining a first working frequency band among at least two working frequency bands of the communication base station; the first working frequency band represents a working frequency band that the communication base station is frequently accessed;

[0058] Step 102: When the traffic volume of the communication base station decreases, determining whether the communication base station is in a low load mode;

[0059] Step 103: When the communication base station is in the low load mode, control the communication base station to operate in the cell of the first working frequency band and to sleep in the cells of other working frequency bands except the first working frequency band among the at least two working frequency bands.

[0060] In step 101, the specific number of the at least two operating frequency bands can be determined according to the actual situation and is not limited herein. As an example, the at least two operating frequency bands can be three operating frequency bands. For example, the 700 MHz frequency band, the 2.6 GHz frequency band, and the 4.9 GHz frequency band.

[0061] The first operating frequency band represents the operating frequency band to which the communication base station is frequently accessed; the first operating frequency band can be understood as the basic operating frequency band.

[0062] The specific determination process for determining the first operating frequency band among the at least two operating frequency bands of the communication base station can be determined according to the actual situation and is not limited herein. As an example, determining the first operating frequency band among the at least two operating frequency bands of the communication base station can be understood as determining the basic operating frequency band among the at least two operating frequency bands of the communication base station. For example, in a certain triple-band RRU (700 MHz, 2.6 GHz, 4.9 GHz), the basic operating frequency band is determined to be 700 MHz.

[0063] In step 102, the decrease in the traffic volume of the communication base station can be determined according to the actual situation and is not limited herein. The specific determination process for determining whether the communication base station is in the low-load mode can be determined according to the actual situation and is not limited herein. As an example, determining whether the communication base station is in the low-load mode can include detecting a first traffic volume parameter of the cells operating normally in the at least two operating frequency bands; and determining whether the communication base station is in the low-load mode based on the first traffic volume parameter. By determining whether the communication base station is in the low-load mode, a determination result that the communication base station is in the low-load mode or the communication base station is not in the low-load mode is obtained.

[0064] In step 103, the specific control process for controlling the cells of the communication base station operating in the first operating frequency band and the cells of the communication base station in the at least two operating frequency bands other than the first operating frequency band to enter the sleep state can be determined according to the actual situation and is not limited herein. As an example, controlling the cells of the communication base station operating in the first operating frequency band and the cells of the communication base station in the at least two operating frequency bands other than the first operating frequency band to enter the sleep state can be understood as controlling a multi-band mobile communication base station to operate only in the basic operating frequency band, and at the same time, the cells of other frequency bands except the basic operating frequency band enter the sleep state.

[0065] In practical applications, one of the frequency bands of a multi-band mobile communication base station is used as the basic operating frequency band of the multi-band mobile communication base station (hereinafter referred to as the "basic operating frequency band"). When the traffic volume of the multi-band mobile communication base station is small, the multi-band mobile communication base station operates in a low-load mode (hereinafter referred to as the "low-load mode"). The multi-band mobile communication base station only operates on the basic operating frequency band, and at the same time, the cells of other frequency bands except the basic operating frequency band are put into sleep, or the cells of other frequency bands except the basic operating frequency band are allowed to operate in other energy-saving strategy states to achieve the effect of energy saving.

[0066] In the solution of the embodiment of the present application, by using one of the frequency bands of the mobile communication base station in at least two operating frequency bands as the first operating frequency band of the multi-band mobile communication base station, when the traffic volume of the multi-band mobile communication base station is small, the multi-band mobile communication base station operates in a low-load mode, and the multi-band mobile communication base station only operates on the first operating frequency band. At the same time, the cells of other frequency bands except the first operating frequency band are put into sleep, which can reduce the overall power consumption of the multi-band mobile communication base station to achieve the effect of energy saving.

[0067] In one embodiment, the determination of whether the communication base station is in the low-load mode includes:

[0068] Detecting a first traffic volume parameter of a cell that is operating normally in the at least two operating frequency bands;

[0069] Based on the first traffic volume parameter, determining whether the communication base station is in the low-load mode.

[0070] Among them, the first traffic volume parameter can be determined according to the actual situation and is not limited herein. As an example, the first traffic volume parameter may include a first user parameter of RRC, a first utilization rate parameter of downlink PRB, and a second utilization rate parameter of uplink PRB.

[0071] The specific judgment process for determining whether the communication base station is in the low-load mode based on the first traffic parameter can be determined according to the actual situation and is not limited herein. As an example, determining whether the communication base station is in the low-load mode based on the first traffic parameter may include determining whether the value of the first user parameter is less than a first threshold, whether the value of the first utilization rate parameter is less than a second threshold, and whether the value of the second utilization rate parameter is less than a third threshold; the first threshold, the second threshold, and the third threshold all represent the energy-saving trigger threshold of the communication base station; when the value of the first user parameter is less than the first threshold, the value of the first utilization rate parameter is less than the second threshold, and the value of the second utilization rate parameter is less than the third threshold, it is determined that the communication base station is in the low-load mode; when the value of the first user parameter is not less than the first threshold or the value of the first utilization rate parameter is not less than the second threshold or the value of the second utilization rate parameter is not less than the third threshold, it is determined that the communication base station is not in the low-load mode.

[0072] In one embodiment, the first traffic parameter includes a first user parameter of RRC, a first utilization rate parameter of downlink PRB, and a second utilization rate parameter of uplink PRB; determining whether the communication base station is in the low-load mode based on the first traffic parameter includes:

[0073] Determining whether the value of the first user parameter is less than a first threshold, whether the value of the first utilization rate parameter is less than a second threshold, and whether the value of the second utilization rate parameter is less than a third threshold; the first threshold, the second threshold, and the third threshold all represent the energy-saving trigger threshold of the communication base station;

[0074] When the value of the first user parameter is less than the first threshold, the value of the first utilization rate parameter is less than the second threshold, and the value of the second utilization rate parameter is less than the third threshold, it is determined that the communication base station is in the low-load mode;

[0075] When the value of the first user parameter is not less than the first threshold or the value of the first utilization rate parameter is not less than the second threshold or the value of the second utilization rate parameter is not less than the third threshold, it is determined that the communication base station is not in the low-load mode.

[0076] Among them, the first user parameter of RRC, the first utilization rate parameter of downlink PRB, and the second utilization rate parameter of uplink PRB can all be determined according to the actual situation and are not limited herein. As an example, the first user parameter of RRC may include the number of RRC users N1; the first utilization rate parameter of downlink PRB may include the downlink PRB utilization rate P1; the second utilization rate parameter of uplink PRB may include the uplink PRB utilization rate Q1.

[0077] The first threshold, the second threshold, and the third threshold all represent the energy-saving trigger threshold of the communication base station; among them, the first threshold, the second threshold, and the third threshold can all be determined according to the actual situation and are not limited herein. The first threshold, the second threshold, and the third threshold can all be understood as trigger thresholds. The first threshold, the second threshold, and the third threshold can be respectively denoted as N J , P J , Q J .

[0078] In practical applications, the energy-saving trigger threshold consists of the following three key parameters: the number of RRC users N J , the downlink PRB utilization rate P J , and the uplink PRB utilization rate Q J . The trigger threshold can be set. As an example, when the base station traffic decreases, the base station detects the cell parameters of the cells operating normally on the 700 MHz, 2.6 GHz, and 4.9 GHz frequency bands, and based on the actual number of RRC users N1, downlink PRB utilization rate P1, and uplink PRB utilization rate Q1 at this time, and the energy-saving trigger thresholds N J , P J , Q J are respectively compared to determine whether the communication base station is in a low-load mode or not in a low-load mode.

[0079] For ease of understanding, as an example, a certain three-band RRU, the three bands are 700 MHz, 2.6 GHz, and 4.9 GHz, with 700 MHz as the basic operating frequency band, first the traffic decreases and enters the energy-saving state, and then the traffic increases to wake up the cell. The 700 MHz frequency band operates normally, and the NR mode and the LTE mode coexist; the 2.6 GHz and 4.9 GHz frequency bands operate normally, 2.6 GHz supports the NR and LTE modes, and 4.9G supports the NR mode. When the base station traffic decreases, the base station detects the cell parameters of the cells operating normally on the 700 MHz, 2.6 GHz, and 4.9 GHz frequency bands, and based on the actual number of RRC users N1, downlink PRB utilization rate P1, and uplink PRB utilization rate Q1 at this time, and the energy-saving trigger thresholds N J , P J , Q J are respectively compared. Typically, when the situation of N1 < N J and P1 < P J and Q1 < Q J occurs, according to the trigger threshold judgment principle, the cells on the 2.6 GHz and 4.9 GHz frequency bands are set to enter the energy-saving state.

[0080] In one embodiment, the method further includes:

[0081] When the traffic volume of the communication base station increases, detect a second traffic volume parameter of a cell operating normally in the first operating frequency band;

[0082] Based on the second traffic volume parameter, determine whether there is a cell to resume on the other operating frequency bands.

[0083] In this embodiment, the second traffic volume parameter can be determined according to the actual situation and is not limited herein. As an example, the second traffic volume parameter may include at least one of the following: a second user parameter of RRC; a third utilization rate parameter of a downlink PRB; a fourth utilization rate parameter of an uplink PRB.

[0084] When the traffic volume of the communication base station increases, detecting a second traffic volume parameter of a cell operating normally in the first operating frequency band can be understood as detecting a second traffic volume parameter of a cell operating normally in the basic operating frequency band when the traffic volume of the communication base station increases.

[0085] The specific determination process of determining whether there is a cell to resume on the other operating frequency bands based on the second traffic volume parameter can be determined according to the actual situation and is not limited herein. As an example, determining whether there is a cell to resume on the other operating frequency bands based on the second traffic volume parameter may include determining whether the value of the second user parameter is less than a fourth threshold, whether the value of the third utilization rate parameter is less than a fifth threshold, and whether the value of the fourth utilization rate parameter is less than a sixth threshold; the fourth threshold, the fifth threshold, and the sixth threshold all represent the wake-up threshold values of the other frequency bands; in the case where the value of the second user parameter is greater than or equal to the fourth threshold; or, the value of the third utilization rate parameter is greater than or equal to the fifth threshold; or, the value of the fourth utilization rate parameter is greater than or equal to the sixth threshold, it is determined that there is a cell to resume on the other operating frequency bands; in the case where the value of the second user parameter is less than the fourth threshold, the value of the third utilization rate parameter is less than the fifth threshold, and the value of the fourth utilization rate parameter is less than the sixth threshold, it is determined that there is no cell to resume on the other operating frequency bands.

[0086] In one embodiment, the second traffic volume parameter includes at least one of the following:

[0087] A second user parameter of RRC;

[0088] A third utilization rate parameter of a downlink PRB;

[0089] A fourth utilization rate parameter of an uplink PRB.

[0090] Among them, the second user parameter of the RRC, the third utilization rate parameter of the downlink PRB, and the fourth utilization rate parameter of the uplink PRB can all be determined according to the actual situation and are not limited herein. As an example, the second user parameter of the RRC may include the actual number of RRC users N2; the third utilization rate parameter of the downlink PRB may include the downlink PRB utilization rate P2; and the fourth utilization rate parameter of the uplink PRB may include the uplink PRB utilization rate Q2.

[0091] In one embodiment, determining whether to resume the cell on the other operating frequency band based on the second traffic parameter includes:

[0092] Determining whether the value of the second user parameter is less than a fourth threshold, whether the value of the third utilization rate parameter is less than a fifth threshold, and whether the value of the fourth utilization rate parameter is less than a sixth threshold; the fourth threshold, the fifth threshold, and the sixth threshold all represent the wake-up threshold value of the other frequency band;

[0093] In the case where the value of the second user parameter is greater than or equal to the fourth threshold; or, the value of the third utilization rate parameter is greater than or equal to the fifth threshold; or, the value of the fourth utilization rate parameter is greater than or equal to the sixth threshold, it is determined that there is a cell to resume on the other operating frequency band;

[0094] In the case where the value of the second user parameter is less than the fourth threshold, the value of the third utilization rate parameter is less than the fifth threshold, and the value of the fourth utilization rate parameter is less than the sixth threshold, it is determined that there is no cell to resume on the other operating frequency band.

[0095] Among them, the fourth threshold, the fifth threshold, and the sixth threshold all represent the wake-up threshold value of the other frequency band; among them, the fourth threshold, the fifth threshold, and the sixth threshold can all be determined according to the actual situation and are not limited herein. The first threshold, the second threshold, and the third threshold can all be understood as recovery thresholds. The fourth threshold, the fifth threshold, and the sixth threshold can be respectively denoted as N H 、P H 、Q H 。

[0096] For ease of understanding, as an example, for a certain three - frequency RRU with three frequencies of 700 MHz, 2.6 GHz, and 4.9 GHz, taking 700 MHz as the basic operating frequency band, the typical process of first experiencing a service decline and entering the energy - saving state, and then the service rising and waking up the cell. The 700 - MHz frequency band operates normally, and both the NR mode and the LTE mode coexist; the 2.6 - GHz and 4.9 - GHz frequency bands operate normally. The 2.6 - GHz band supports both NR and LTE modes, and the 4.9 - GHz band supports the NR mode. When the base - station traffic volume rises, the base station detects the cell parameters of the cells operating normally on the 700 - MHz frequency band, and based on the actual number of RRC users N2, downlink PRB utilization rate P2, and uplink PRB utilization rate Q2 at this time, and the recovery trigger thresholds N H 、P H 、Q H Compare them respectively. When N2≥N H or P2≥P H or Q2≥Q H (that is, as long as one of the parameters reaches the recovery threshold), according to but not limited to the judgment principle in Example 2, wake up the energy - saving cells on the 2.6 - GHz and 4.9 - GHz frequency bands, or wake up the energy - saving cells on a certain frequency band (according to the trigger - threshold gear). If the judgment principle causes all the energy - saving cells to be woken up, the energy - saving mode exits, and the base station resumes the state of full - frequency - band and full - cell activation.

[0097] When specifically configuring the trigger threshold, N J 、P J 、Q J and N H 、P H 、Q H can be respectively configured with the same value, or to avoid ping - pong handover, N J 、P J 、Q J can be slightly smaller than N H 、P H 、Q H .

[0098] In one embodiment, after there is a recovery of the cells on the other operating frequency bands, the method further includes:

[0099] Obtain the priority parameters for configuring at least one of the other operating frequency bands;

[0100] Based on the priority parameters, preferentially recover the operating frequency band with the highest priority among the other operating frequency bands.

[0101] Among them, the priority parameters can be determined according to the actual situation and are not limited herein. As an example, the priority parameters may include frequency - point priorities.

[0102] Prioritizing the restoration of the operating band with the highest priority among the other operating bands based on the priority parameter can be understood as prioritizing the wake-up of the operating band with the highest priority among the other operating bands based on the priority parameter.

[0103] In practical applications, when a cell is woken up, the frequency point selection is based on the frequency point priority configured by the network management. For example, if the wake-up priority of a 2.6 GHz NR cell configured by the user is higher than that of a 4.9 GHz NR cell, then cell1 and cell2 are woken up first. If more cells still need to be woken up, then cell3 and cell4 are woken up until all cells are woken up.

[0104] In one embodiment, after restoring the cells on the other operating bands, the method further includes:

[0105] Obtaining at least one cell set corresponding to the cells to be restored on the other operating bands;

[0106] Determining the third user parameter of the radio resource control (RRC) of all cell loads, the fifth utilization rate parameter of the downlink physical resource block (PRB), and the sixth utilization rate parameter of the uplink physical resource block (PRB) in each of the cell sets;

[0107] Determining a target cell set with the smallest number of cells in the at least one cell set based on the third user parameter, the fifth utilization rate parameter, and the sixth utilization rate parameter;

[0108] Restoring the operating band corresponding to the target cell set.

[0109] In this embodiment, the specific number of the at least one cell set can be determined according to the actual situation and is not limited herein. As an example, the at least one cell set can be three cell sets. These three cell sets can be denoted as cell set X, Y, and Z. For example, for the 5G NR cell distribution of a certain three-band base station, the 4.9 GHz NR cells are distributed as cell3 and cell4; the 2.6 GHz NR cells are distributed as cell1 and cell2; the 700 GHz NR cell is distributed as cell10. Among them, cell set X can include cells cell0 and cell1; cell set Y can include cells cell0 and cell2; cell set Z can include cells cell0, cell1, and cell2.

[0110] The third user parameter of the RRC, the fifth utilization rate parameter of the downlink PRB, and the sixth utilization rate parameter of the uplink PRB can all be determined according to the actual situation and are not limited herein. As an example, the third user parameter of the RRC may include the actual number of RRC users N2; the fifth utilization rate parameter of the downlink PRB may include the downlink PRB utilization rate P2; the sixth utilization rate parameter of the uplink PRB may include the uplink PRB utilization rate Q2.

[0111] As an example, comparing the current load parameters of cell0 in the above table, when N2≥N H or P2≥P H or Q2≥Q H , that is, when one of the three key parameters of the current load reaches the load trigger threshold, the cell wake-up is started.

[0112] When the cell wakes up, the frequency point selection is based on the frequency point priority configured by the network management. For example, if the wake-up priority of the 2.6 GHz NR cell configured by the user is higher than that of the 4.9 GHz NR cell, cell1 and cell2 are preferentially woken up. If there is still a need to wake up, then cell3 and cell4 are woken up until all are woken up.

[0113] Typically, the following situations will occur in the cell wake-up order.

[0114] Situation 1: After cell0 wakes up cell1 and shares the load, the load of cell0 or cell1 still exceeds the trigger threshold, and cell2 needs to be woken up continuously. However, if cell0 directly wakes up cell2 and shares the load, and the load of cell0 or cell2 is lower than the trigger threshold, there is no need to wake up cell1 continuously.

[0115] In Situation 1, 2 cells are woken up in the former case, and 1 cell is woken up in the latter case. The latter case has lower energy consumption than the former case.

[0116] For Situation 1, this embodiment gives the following strategy to determine the wake-up priority of the cell: compare the sets of cells X (including cells cell0 and cell1), Y (including cells cell0 and cell2), and Z (including cells cell0, cell1, and cell2) after wake-up; the comparison method is to add up the RRC user numbers, downlink PRB utilization rates, and uplink PRB utilization rates of all cells in the set and then compare. While satisfying that the load is lower than the trigger threshold, the set with the fewest number of woken-up cells wins.

[0117] In one embodiment, after restoring the cells on the other working frequency bands, the method further includes:

[0118] Determine the sorting result of the priority of the load parameters of the cells on the other operating frequency bands;

[0119] Compare the load parameters of multiple cells to be restored according to the sorting result to obtain the target cell corresponding to the maximum value of the load parameters among the load parameters of the multiple cells to be restored;

[0120] Restore the operating frequency band corresponding to the target cell.

[0121] In this embodiment, the load parameters can be determined according to the actual situation and are not limited herein. As an example, the load parameters may include the number of RRC users, the downlink RB utilization rate, and the uplink RB utilization rate.

[0122] The specific determination process of determining the sorting result of the priority of the load parameters of the cells on the other operating frequency bands can be determined according to the actual situation and is not limited herein. As an example, the priority sorting of the load parameters is given as the number of RRC users > the downlink RB utilization rate > the uplink RB utilization rate.

[0123] As an example, in practical applications, the priority sorting of the load parameters is given as (the number of RRC users > the downlink RB utilization rate > the uplink RB utilization rate). When waking up cell1 or waking up cell2 can both reduce the load of the basic coverage cell cell0 and the waking up cell cell1 or cell2 below the trigger threshold, first compare the number of RRC users of cell1 and cell2. If the number of RRC users of cell1 is greater than that of cell2, the energy-saving wake-up priority of cell1 is higher than that of cell2; if the number of RRC users of cell1 and cell2 is equal, then compare the downlink PRB utilization rate, and so on.

[0124] For better understanding, here an example of the energy-saving control method of the communication base station is specifically the energy-saving control method based on the multi-band mobile communication base station. One of the frequency bands of the multi-band mobile communication base station is used in this application as the basic operating frequency band of the multi-band mobile communication base station. When the traffic volume of the multi-band mobile communication base station is small, the multi-band mobile communication base station operates in a low-load mode. The multi-band mobile communication base station only operates on the basic operating frequency band, and at the same time, the cells in the other frequency bands except the basic operating frequency band are put into sleep, or the cells in the other frequency bands except the basic operating frequency band are allowed to operate in other energy-saving strategy states to achieve the energy-saving effect.

[0125] This application needs to maintain the multi-mode network entry on the basic operating frequency band. After the traffic volume of the multi-band mobile communication base station rises to the trigger threshold, the cells on the other operating frequency bands of the multi-band mobile communication base station are restored without affecting the normal capacity and services of the multi-band mobile communication base station.

[0126] Among them, the energy-saving trigger threshold consists of the following three key parameters: the number of RRC users N J , the downlink PRB utilization rate P J , and the uplink PRB utilization rate Q J . The trigger threshold can be set. The series of judgment principles for cell wake-up and trigger threshold in the second example can achieve the energy-saving effect to the greatest extent and are also the core of this patent.

[0127] The following uses embodiments to illustrate the energy-saving control method based on a multi-band mobile communication base station:

[0128] Embodiment 1 is a typical process of a certain three-band RRU that first enters the energy-saving state due to a decrease in traffic and then wakes up the cell when the traffic increases, with 700 MHz as the basic operating band.

[0129] Step 1: A certain three-band RRU (700 MHz + 2.6 GHz + 4.9 GHz), with the basic operating band being 700 MHz. The 700 MHz band operates normally, and the NR mode and LTE mode coexist; the 2.6 GHz and 4.9 GHz bands operate normally, 2.6 GHz supports both NR and LTE modes, and 4.9 GHz supports the NR mode.

[0130] Step 2: When the base station traffic decreases, the base station detects the cell parameters of the cells operating normally on the 700 MHz, 2.6 GHz, and 4.9 GHz bands, and based on the actual number of RRC users N1, downlink PRB utilization rate P1, and uplink PRB utilization rate Q1 at this time, and the energy-saving trigger threshold N J , P J , Q J are compared respectively. Typically, when N1 < N J and P1 < P J and Q1 < Q J occur, according to but not limited to the trigger threshold judgment principle in the second example, the cells on the 2.6 GHz and 4.9 GHz bands are set to enter the energy-saving state.

[0131] After the cell enters the energy-saving state, the 700 MHz band operates normally, and the 5G mode and LTE mode coexist; the 2.6 GHz and 4.9 GHz bands become energy-saving bands, and the cells on these two bands do not operate and enter the intelligent shutdown state. At this time, the power consumption of the base station equipment is reduced, achieving the energy-saving effect.

[0132] Step 3: When the base station traffic increases, the base station detects the cell parameters of the cells operating normally on the 700 MHz band, and based on the actual number of RRC users N2, downlink PRB utilization rate P2, and uplink PRB utilization rate Q2 at this time, and the recovery trigger threshold N H , P H , Q HCompare them separately. When N2≥N H or P2≥P H or Q2≥Q H (that is, as long as one of the parameters reaches the recovery threshold), according to but not limited to the judgment principle in the second embodiment, wake up the energy-saving cells on the 2.6 GHz and 4.9 GHz frequency bands, or wake up the energy-saving cells on a certain frequency band (according to the trigger threshold gear). If the judgment principle causes all the energy-saving cells to be woken up, the energy-saving mode exits, and the base station resumes the state of full-frequency band and full-cell activation.

[0133] When specifically configuring the trigger threshold, N J , P J , Q J and N H , P H , Q H can be respectively configured with the same value, or to avoid ping-pong handover, N J , P J , Q J can be slightly smaller than N H , P H , Q H slightly.

[0134] The second embodiment is the typical judgment principle for cell wake-up and trigger threshold of a 5G NR cell of a certain three-frequency base station when the traffic volume increases. It can be understood in combination with Table 1, and Table 1 is a schematic table of the distribution of 5G NR cells of a certain three-frequency base station.

[0135] Table 1

[0136]

[0137] When the traffic volume of the base station increases, compare the current load of the basic coverage cell cell0 with the trigger threshold. It can be understood in combination with Table 2, and Table 2 is a schematic table for comparing the current load of the basic coverage cell cell0 with the trigger threshold when the traffic volume of the base station increases.

[0138] Table 2

[0139]

[0140]

[0141] Compare the current load parameters of cell0 in the above table. When N2≥N H or P2≥P H or Q2≥Q H , that is, when one of the three key parameters of the current load reaches the load trigger threshold, start cell wake-up.

[0142] When the cell is awakened, the frequency point selection is based on the frequency point priority configured by the network management. For example, if the awakening priority of the 2.6 GHz NR cell configured by the user is higher than that of the 4.9 GHz NR cell, cell1 and cell2 are awakened first. If more awakenings are still needed, then cell3 and cell4 are awakened until all are awakened.

[0143] Typically, the following situations occur in the cell awakening sequence.

[0144] In Case 1, after cell0 awakens cell1 and shares the load, the load of cell0 or cell1 still exceeds the trigger threshold, and cell2 needs to be awakened continuously. However, if cell0 directly awakens cell2 and shares the load, and the load of cell0 or cell2 is lower than the trigger threshold, there is no need to awaken cell1 continuously.

[0145] In Case 1, the former 2 cells are awakened, and the latter 1 cell is awakened. The latter has lower energy consumption than the former.

[0146] For Case 1, this embodiment gives the following strategy to determine the awakening priority of the cell: Compare the set X of cells after awakening (including cell0 and cell1), set Y (including cell0 and cell2), and set Z (including cell0, cell1, and cell2); The comparison method is to add up the RRC user numbers, downlink PRB utilization rates, and uplink PRB utilization rates of all cells in the set and then compare them. While satisfying that the load is lower than the trigger threshold, the set with the fewest awakened cells wins.

[0147] In Case 2, cell1 and cell2 themselves have other energy-saving strategies and operate in an energy-saving state with low load. Awakening cell1 and sharing the load, or awakening cell2 and sharing the load, can both meet the condition that the load after awakening is lower than the trigger threshold.

[0148] For Case 2, this embodiment gives the following strategy: The priority order of the load parameters is given as (RRC user number > downlink RB utilization rate > uplink RB utilization rate). When awakening cell1 or cell2 can reduce the load of the basic coverage cell0 and the awakened cell1 or cell2 below the trigger threshold, first compare the RRC user numbers of cell1 and cell2. If the RRC user number of cell1 is greater than that of cell2, the energy-saving awakening priority of cell1 is higher than that of cell2; If the RRC user numbers of cell1 and cell2 are equal, then compare the downlink PRB utilization rate, and so on.

[0149] An embodiment of the present application describes an energy-saving control method for a multi-band mobile communication base station, including defining key parameters such as a basic operating band, a trigger threshold, and several typical strategies for cell wake-up and trigger conditions, etc. The typical strategies in the present application and the embodiment are not single and isolated energy-saving methods, and can also be combined with other energy-saving methods for the base station, including but not limited to channel shutdown, symbol shutdown, deep sleep, and all other necessary energy-saving methods.

The programs and codes implemented by software in the embodiment of the present application can be stored in, including but not limited to, the internal software platform of the base station, the network management server, the network management client, or a third-party memory and computer.

[0150] An embodiment of the present application uses one of the bands of the multi-band mobile communication base station as the basic operating band of the multi-band mobile communication base station. When the traffic volume of the multi-band mobile communication base station is small, the multi-band mobile communication base station operates in a low-load mode. The multi-band mobile communication base station only operates on the basic operating band, and at the same time, the cells of other bands except the basic operating band are put into sleep, or the cells of other bands except the basic operating band are allowed to operate in other energy-saving strategy states to achieve the effect of energy saving.

[0151] An embodiment of the present application triggers whether to resume the operation of other bands through the configuration of key parameters. The trigger threshold consists of the following three key parameters: the number of RRC users N, the downlink PRB utilization rate P, and the uplink PRB utilization rate Q.
