Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to a cell power adjustment method and device. BACKGROUND

[0002] The power consumption problem in the communication network has been the focus of major operators and equipment manufacturers, which is directly related to the performance of the device and the operating cost. The power setting of the cell is directly related to the power consumption of the base station, and the current 4\5G network basic power setting technology can only make static adjustment:

[0003] (1) 4G network: first set the basic parameter "reference signal received power", and then realize the power configuration of symbol and channel level through (pa, pb) and open loop and closed loop power control on this basis.

[0004] (2) 5G network: first set the basic "channel power", and then realize the power configuration of channel level according to the power offset of each channel on this basis.

[0005] It can be found that in the 4G network or the 5G network, the power setting of the existing network can only adjust the power based on the open loop, the closed loop and the offset based on the determined channel basic power. The setting of the channel basic power can only be adjusted by a one-size-fits-all method according to the on-site test or manual experience, which is not fine enough, which leads to the inaccuracy of the coverage of the cell. In order to ensure that as many users as possible can be accessed, the power is often increased in large quantities, which leads to the surge of power consumption, and also leads to the waste of power due to improper coverage.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0042] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in this specification and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0043] The terms "including," "comprising" and "having" are intended to be open-ended terms that mean the named element is present but not excluding additional elements.

[0044] Figure 1 is a flowchart of the cell power adjustment method provided by the present application. As shown in Figure 1 the cell power adjustment method provided by the present application comprises: step 101, obtaining a first weight and a second weight of a target TA interval at a t time based on the number of users, the corresponding distance value and the number of handover requests of each TA interval of the target TA interval at the t time.

[0045] The target TA interval is the TA interval with the largest TA value among the TA intervals.

[0046] It is to be noted that the execution subject of the cell power adjustment method provided by the present application is a cell power adjustment device. The cell power adjustment device can be arranged on a base station, and the adjustment object of the cell power adjustment device is the power of a certain cell in the base station where the device is located. The type of the power is not specifically limited in the present application, for example, it can be the actual configured power of the cell, or the basic power of the cell.

[0047] The t time refers to the time when the cell power adjustment device executes the cell power adjustment method. Before this time, the basic power of the cell has not been adjusted by the cell power adjustment method. The setting of the t time is not specifically limited in the present application, for example, it can be a time given by a person, or a time when the cell power adjustment device automatically executes the cell power adjustment method.

[0048] The target cell refers to a cell to be adjusted in power by the cell power adjustment device.

[0049] Timing Advance (TA) refers to estimating the radio frequency transmission delay caused by distance to send data packets in advance by a corresponding time in order to make the user terminal (User Equipment, UE) uplink packets arrive at the base station at the desired time. TA is generally used for UE uplink transmission, which can represent the distance between UE and antenna port, that is, the TA value of the UE at the center of the cell coverage range is smaller, and the TA value of the UE at the edge of the cell coverage range is larger. The embodiment of the present application does not make specific limitation to the acquisition method of TA value.

[0050] For example, it can be in the initial access process, the transmission reception point (Transmission Reception Point, TRP) determines the TA value by measuring the position where the peak value of the random access channel (Random Access Channel, RACH) signal packet data protocol (Packet Data Protocol, PDP) energy is located.

[0051] TA interval refers to a set of TA values within a certain range, which at least contains one TA value, and multiple TA values in the set are continuous. Multiple TA intervals are also continuous.

[0052] Target TA interval refers to an interval including the maximum TA value, and the target TA interval can represent the edge user in the cell coverage range.

[0053] Handover request refers to the request information of the UE in the cell coverage range to the base station where the cell is located to switch to other cells or base stations.

[0054] It should be noted that the number of users refers to that before step 101, the cell power adjustment device acquires the TA value of each UE according to the uplink situation of the UE in the cell range at a certain time, and counts the number of UEs under each TA interval and the total number of UE sending handover request by comparing the division of TA interval.

[0055] Specifically, in step 101, at a given time t, the cell power adjustment device acquires the distribution of TA values of each UE in any target cell on the TA interval, and obtains the first weight W of the target TA interval according to the number of users corresponding to the TA value of each TA interval and the distance value (t) , and obtains the second weight E of the target TA interval according to the distance value corresponding to the TA value of each TA interval and the total number of handover requests corresponding to the TA value (t) .

[0056] The first weight W (t)is the proportion of the number of edge users (i.e., UEs in the target TA interval) and the distance in the entire cell coverage range (i.e., all TA intervals) at the t th moment. The smaller the first weight, the smaller the number of edge users and the distance of edge users in the coverage range. Conversely, the larger the first weight, the larger the number of edge users and the distance of edge users in the coverage range.

[0057] Second weight E (t) is the proportion of edge users (i.e., UEs in the target TA interval) intending to move to other places and interact with neighboring cells in the entire cell coverage range (i.e., all TA intervals) at the t th moment. The smaller the second weight, the more edge users are still in the coverage range of the target cell, and the original coverage range should be maintained at least for communication with the edge users. The larger the second weight, the more edge users frequently interact with other cells due to mobility, and the coverage range of the target cell can be reduced because the communication with these edge users has been disconnected.

[0058] Optionally, in the 4G network, at a given moment t, the cell power adjustment device obtains the first weight for determining the distribution state of edge users according to the number of users and the distance value corresponding to the TA value of each TA interval in any target cell, and obtains the second weight for determining the movement state of edge users according to the number of handover requests and the distance value corresponding to the TA value of each TA interval.

[0059] In the 4G network, the distance value corresponding to a TA value is calculated with reference to 1Ts, i.e., TA = 1, then N_TA = 1*16Ts, and the distance represented is 16*4.89 = 78.12 meters (m), which is about 78 m. Similarly, if the TA value is 2, the corresponding distance value is about 78*2 = 156 m.

[0060] Optionally, in the 5G network, at a given moment t, the cell power adjustment device obtains the first weight for determining the distribution state of edge users according to the TA value, the number of users and the distance value of each TA interval in any target cell, and obtains the second weight for determining the movement state of edge users according to the TA value and the number of handover requests of each TA interval.

[0061] In the 5G network, the distance value corresponding to a TA value is calculated with reference to 1Tc, which is different from 16Ts in the 4G network. The granularity of the 5G cell TA changes with the subcarrier spacing and system bandwidth, and the change trend is shown in Table 1.

[0062] Table 1: 5G cell TA corresponding distance value table

[0063] μ Subcarrier spacing TA accuracy (seconds) TA distance (meters) 0 15 16*64*1Tc 78.125 1 30 16*32*1Tc 39.0625 2 60 16*16*1Tc 19.53125 3 120 16*8*1Tc 9.765625

[0064] That is, TA=1, if the subcarrier spacing is 15, the distance represented is 78.125 m, in the case of TA value is 2, the corresponding distance value is about 78.125*2=156.25 m. Similarly, if the subcarrier spacing is 120, the distance represented is 9.765625 m, in the case of TA value is 3, the corresponding distance value is about 9.765625*2=29.296875 m.

[0065] Step 102, in the case that the first weight and the second weight of the target TA interval at the t time meet the target condition, acquiring the power of the target cell at the t time based on the power of the target cell at the (t-1) time.

[0066] Wherein, the power of the target cell at the t time is less than the power of the target cell at the (t-1) time.

[0067] It should be noted that the cell power adjustment device acquires the first weight and the second weight of the target TA interval at each time, that is, before step 102, the first weight W (t-n) and the second weight E (t-n) of each t-n time in the time period before the t time are also acquired, so as to judge whether the cell coverage range changes through the user distribution state and the moving state of the continuous time, and then adaptively adjust the cell power.

[0068] The target condition refers to the first weight W (t) and the second weight E (t) of the t time meet the condition of power contraction, that is, the distribution state and the moving state of the edge user in the t time are both reduced compared with the (t-1) time. The embodiment of the application is not limited specifically.

[0069] For example, the target condition can be W (t) <W (t-1) and E (t) <E (t-1) , wherein W (t-1) is the first weight of the target TA interval at the (t-1) time, and E (t-1) is the second weight of the target TA interval at the (t-1) time.

[0070] Specifically, in step 102, the cell power adjustment device compares the first weight W (t) and the second weight E (t) of the t time acquired in step 101 with the target condition set in advance, and adjusts the power of the target cell at the (t-1) time corresponding to the state change through the distribution state change and the moving state change of the UE in the target TA interval at the t time and before the t time, so as to acquire the power of the target cell at the t time.

[0071] W (t) <W (t-1) and E (t) <E (t-1) , it is proved that the edge user distribution of the cell at the tth moment is lower than the value at the (t-1)th moment, the edge user in the cell is reduced, and the mobility is also weakened, i.e. the cell coverage at the (t-1)th moment is larger than the range constituted by the edge user at the tth moment, so the power of the target cell can be adaptively shrunk to make the cell coverage area after shrinking just cover the range constituted by the edge user at the tth moment. Assuming that the basic power of the target cell at the (t-1)th moment is Pr (t-1) , the basic power Pr (t) at the tth moment is:

[0072] Pr (t) = Pr (t-1) -a

[0073] wherein a is the degree of power shrinkage, and the embodiment of the present application does not make specific limitation to the value of a. For example, a can be a constant or a variable.

[0074] After power shrinkage, Pr (t) <Pr (t-1) , so the cell coverage at the tth moment is smaller than the cell coverage at the (t-1)th moment.

[0075] On the contrary, if W (t) ≥W (t-1) and E (t) ≥E (t-1) , the power of Pr (t-1) does not need to be shrunk.

[0076] Preferably, if W (t) <W (t-1) and E (t) <E (t-1) and W (t) <W (max) and E (t) <E (max) , it is proved that the edge user distribution of the cell at the tth moment is lower than the maximum value within a certain time and the value at the (t-1)th moment, the edge user distribution of the cell is reduced, and the mobility is also weakened, so the power of Pr (t-1) can be shrunk to make the cell coverage area after shrinking just cover the edge user at the tth moment.

[0077] Similarly, on the contrary, if W (t) <W (t-1) , E (t) <E (t-1) , W(t) <W (max) and E (t) <E (max) , power scaling is not necessary for Pr (t-1) .

[0078] wherein, W (max) is the maximum value of the first weight of the target TA interval in the time period before the t th moment, and E (t-1) is the maximum value of the second weight of the target TA interval in the time period before the t th moment.

[0079] The embodiment of the application obtains the first weight and the second weight of the target TA interval based on the number of users at the t th moment, the corresponding distance value and the number of switching requests, and adjusts the power of the cell according to the distribution state change and the movement state change of the edge users after power scaling at the (t-1) th moment as the power at the t th moment, thereby improving the precision of power adjustment.

[0080] On the basis of any of the above embodiments, in the case where the first weight and the second weight of the target TA interval at the t th moment meet the target condition, the power of the target cell at the t th moment is obtained based on the power of the target cell at the (t-1) th moment, and the method comprises: in the case where the first weight of the target TA interval at the t th moment is less than the first weight at the (t-1) th moment, the second weight of the target TA interval at the t th moment is less than the second weight at the (t-1) th moment, and the target identifier is in the first state, the power of the target cell at the t th moment is obtained based on the power of the target cell at the (t-1) th moment and the target step, the target identifier is adjusted to the second state, and the value of the target parameter is updated based on a preset rule.

[0081] wherein, the target step is obtained based on the current value of the target parameter.

[0082] It should be noted that the target identifier is a mark used to distinguish whether the target cell has performed power scaling at the current moment. The target identifier comprises two states: the first state and the second state. The first state means that the target cell performs power scaling at the current moment, and the second state means that the target cell does not perform power scaling at the current moment. The form of the target identifier is not limited in the embodiment of the application.

[0083] For example, the target identifier can be a field named "PTAG", the first state of the target identifier can be "PTAG=FALSE", and the second state of the target identifier can be "PTAG=TRUE".

[0084] It should be noted that before step 102, the cell power adjustment device sets the initial value of the target identifier at the t time as the first state, i.e. indicating that no power shrinkage has been performed before the t time.

[0085] Specifically, in step 102, in the W (t) <W (t-1) and E (t) <E (t-1) and PTAG=FALSE, the cell power adjustment device performs power shrinkage according to Pr (t-1) and the target step length to obtain Pr (t) , and resets PTAG as TRUE.

[0086] The target step length refers to the size of the shrunk power value, and different power adjustment schemes correspond to different target step lengths.

[0087] Preferably, if W (t) <W (t-1) and E (t) <E (t-1) and W (t) <W (max) and E (t) <E (max) , and PTAG=FALSE is also satisfied, the adjustment scheme of Pr (t) is as follows:

[0088] Pr (t) =Pr (t-1) -f(δ t ,k t )

[0089] Wherein, f(δ,k) is the expression of the target step length of the kth power adjustment, and is as follows:

[0090]

[0091] Wherein, the adjustment times k (t) corresponds to the time t. Since the t time is the initial execution time of the cell power adjustment method, the corresponding k (t) is the initial value, and δ (t) is the initial value. Subsequently, the k value is increased by 1 and the δ value is doubled, i.e. δ (t) =2δ (t-1) , every time the adjustment is performed. The k value is reset as the initial value after the zero point of the day. The setting method of f(δ (t) ,k (t) ) in the subsequent steps is the same as this. The present embodiment does not make specific limitation to the values of k (t) and δ (t) .

[0092] Preferably, k(t) = 1, δ (t) = 3 dB.

[0093] The embodiment of the application is based on the first weight and the second weight of the target TA interval at the tth moment, meets the target condition, and the target identifier is in the first state. In this case, the power at the (t-1)th moment is contracted by the target step, and then the power at the tth moment is obtained. According to the distribution state change, the moving state change and the target identifier of the edge user, the power of the cell is dynamically adjusted by the target step, and the precision of the power adjustment is improved.

[0094] On the basis of any of the above embodiments, the first weight and the second weight of the target TA interval at the tth moment of the target cell are obtained based on the number of users, the corresponding distance value and the number of handover requests of each TA interval of the target cell at the tth moment, including: based on the number of users and the corresponding distance value of each TA interval of the target cell at the tth moment, the first weight of the target TA interval of the target cell at the tth moment is obtained, and the second weight of the target TA interval of the target cell at the tth moment is obtained based on the number of handover requests and the corresponding distance value of each TA interval of the target cell at the tth moment.

[0095] Specifically, in step 101, for a given tth moment, it is assumed that the user TA value interval distribution of the target cell j is 1-n, the distance value corresponding to the TA value of the ith interval is The number of UE users in each interval i is Then the first weight of the proportion of the interval with the maximum TA value in the target cell j is obtained The calculation method of

[0096]

[0097] Wherein, The proportion of the edge user under the coverage of the target cell j.

[0098] The number of users in the maximum TA value interval is The distance value corresponding to the maximum TA value is The weighted value of the number of users and the distance value of the target TA interval reflects the number of remote edge users and the distance distribution.

[0099] The weighted value of all different TA interval users under the cell j reflects the overall distribution of users.

[0100] The number of handover requests in each interval i under the TA interval 1-n of the target cell j is P i (t) The second weight of the proportion of the interval with the maximum TA value in the target cell j is obtained The calculation method is as follows:

[0101]

[0102] Wherein, is the moving state of the edge user in the coverage range of the target cell j relative to the total user.

[0103] is the total number of handover requests of the user in the maximum TA value interval, is the weighted value of the number of mobile handover requests and the distance value of the user in the target TA interval, reflecting the moving state of the edge user in the coverage range.

[0104] is the weighted value of the number of mobile handover requests and the distance value of all users in the TA interval, reflecting the moving state of all edge users in the coverage range.

[0105] The embodiment of the application obtains a first state based on the number of users in each TA interval and the corresponding distance value at the tth moment, and obtains a second state based on the number of handover requests in each TA interval and the corresponding distance value at the tth moment. According to the first state and the second state, the distribution state and the moving state of the edge user can be determined, and further, the cell power can be dynamically adjusted according to the distribution state change, the moving state change and the target identifier, and the precision of power adjustment is improved.

[0106] On the basis of any of the above embodiments, in the case that the first weight of the target TA interval at the tth moment is less than the first weight at the (t-1)th moment, the second weight of the target TA interval at the tth moment is less than the second weight at the (t-1)th moment, and the target identifier is the first state, the power of the target cell at the tth moment is obtained based on the power of the target cell at the (t-1)th moment and the target step, the target identifier is adjusted to the second state, and after the value of the target parameter is updated based on the preset rule, the method further comprises: obtaining the first weight and the second weight of the target TA interval at the (t+1)th moment based on the number of users, the corresponding distance value and the number of handover requests in each TA interval at the (t+1)th moment.

[0107] Specifically, after the power at the tth moment is contracted in step 102, according to the steps of calculating the first weight and the second weight, the cell power adjustment device obtains the distribution of the TA values of each UE in the target cell at the t+1th moment, the first weight W (t+1) of the target TA interval is obtained according to the number of users and the distance value corresponding to the TA value of each TA interval, and the second weight E (t+1) of the target TA interval is obtained according to the distance value corresponding to the TA value of each TA interval and the total number of handover requests corresponding to the TA value.

[0108] If the first weight at time (t+1) of the target TA interval is less than or equal to the first weight at time t, the second weight at time (t+1) of the target TA interval is less than or equal to the second weight at time t, and the target is identified as the second state, the power of the target cell at time (t+1) is obtained based on the power of the target cell at time t, the target step size, and the first coefficient, and the value of the target parameter is updated based on the preset rule.

[0109] The first coefficient is less than 1.

[0110] It should be noted that the preset rule refers to the update rule for the target parameters k and δ in the target step size f(δ,k). This embodiment of the invention does not specifically limit this rule; it can be the method for setting f(δ,k) as described above.

[0111] Specifically, in W (t+1) ≤W (t) And E (t+1) ≤E (t) And when PTAG = TRUE at time t, using Pr (t) The expression for obtaining the power of the target cell at time (t+1) using the target step size f(6,2) and the first coefficient in this adjustment is as follows:

[0112] Pr (t+1) =Pr (t) -b*f(δ (t+1) ,k (t+1) )

[0113] Where b is the first coefficient, and b < 1.

[0114] Since the time has changed to time t+1, corresponding to the second adjustment of the target cell, the target parameters in the target step size expression need to be updated according to the preset rules. Therefore, at time t+1, the target step size is:

[0115] For example, f(δ) (t+1) ,k (t+1) )=f(2δ (t) ,k (t) +1)=f(2*3,1+1)=f(6,2).

[0116] Preferably, in W (t+1) ≤W (t) And E (t+1) ≤E (t) If PTAG = TRUE at time t, it proves that the distribution of edge users in the target cell has not changed significantly, and the previous power contraction has not had a negative impact. Therefore, it is possible to try another half-step contraction of the power, i.e.

[0117] The embodiment of the application is based on continuing to track the first weight and the second weight of the target TA interval at the (t+1)th moment after power shrinkage at the tth moment, and when the first weight at the (t+1)th moment is less than or equal to the first weight at the tth moment and the second weight at the (t+1)th moment of the target TA interval is less than or equal to the second weight at the tth moment, the power at the tth moment is further shrunk by a target step as the power at the (t+1)th moment, which can dynamically adjust the cell power by the target step according to the distribution state change, the movement state change and the target identification of the edge users at the (t+1)th moment, and improve the precision of power adjustment.

[0118] On the basis of any of the above embodiments, after obtaining the first weight and the second weight of the target TA interval at the (t+1)th moment based on the number of users, the corresponding distance value and the number of handover requests of each TA interval at the (t+1)th moment, the method further comprises: in the case that the first weight at the (t+1)th moment of the target TA interval is greater than the first weight at the tth moment, adjusting the target identification to the first state.

[0119] Specifically, after obtaining the first weight W (t+1) and the second weight E (t+1) of the target TA interval at the (t+1)th moment, in the case that W (t+1) > W (t) , it is proved that the edge user distribution of the cell has a growth trend, and if PTAG at the tth moment is TRUE, the power shrinkage is stopped, real-time tracking is continued, and PTAG at the (t+1)th moment is set to FALSE, which proves that this time the power shrinkage is not performed and the user distribution has growth.

[0120] If PTAG at the tth moment is FALSE, real-time tracking is continued, and PTAG at the (t+1)th moment is kept as FALSE, which proves that this time the power shrinkage is not performed and the user distribution has growth.

[0121] The embodiment of the application is based on continuing to track the first weight and the second weight of the target TA interval at the (t+1)th moment, and when the first weight at the (t+1)th moment is greater than the first weight at the tth moment, the power at the tth moment is not processed as the power at the (t+1)th moment, which can dynamically adjust the cell power by the target step according to the distribution state change, the movement state change and the target identification of the edge users at the (t+1)th moment, and improve the precision of power adjustment.

[0122] On the basis of any one of the above embodiments, based on the number of users, the corresponding distance value and the number of handover requests of each TA interval of the target cell at the t th moment, after obtaining the first weight and the second weight of the target TA interval at the t th moment, the method further comprises: in the case that the first weight of the target TA interval at the t th moment is greater than the first weight of the (t-1) th moment, based on the number of users, the corresponding distance value and the number of handover requests of each TA interval at the (t+1) th moment, obtaining the first weight and the second weight of the target TA interval at the (t+1) th moment.

[0123] Specifically, in step 102, if W (t) > W (t-1) , the power at the t th moment is not contracted, and according to the steps of calculating the first weight and the second weight, the cell power adjustment device obtains the distribution of the TA values of each UE in the target cell at the t+1 th moment in the TA interval, obtains the first weight W (t+1) of the target TA interval according to the number of users and the distance value corresponding to the TA value of each TA interval, and obtains the second weight E (t+1) of the target TA interval according to the distance value corresponding to the TA value of each TA interval and the total number of handover requests corresponding to the TA value.

[0124] In the case that the first weight of the target TA interval at the (t+1) th moment is greater than the first weight at the t th moment, the second weight of the target TA interval at the (t+1) th moment is greater than the second weight at the t th moment, and the target identifier is the first state, based on the power of the target cell at the t th moment, the target step and the second coefficient, the power of the target cell at the (t+1) th moment is obtained, and the value of the target parameter is updated based on the preset rule.

[0125] Wherein, the second coefficient is greater than 1; the power of the target cell at the (t+1) th moment is greater than the power of the target cell at the t th moment.

[0126] It should be noted that since the power at the t th moment is not contracted, PTAG = FALSE at the t th moment.

[0127] Specifically, in the case that W (t+1) > W (t) , E (t+1) > E (t) , and PTAG = FALSE at the t th moment, the expression of the power of the target cell at the (t+1) th moment is obtained by using Pr (t) , the target step f (6, 2) of this adjustment and the second coefficient.

[0128] Pr (t+1) = Pr (t) + c*f (δ (t+1) , k (t+1) )

[0129] Wherein, c is the first coefficient, and c>1.

[0130] Exemplarily, the time is still the t+1 time, only the corresponding adjustment scheme is changed, so the target step of the t+1 time is still f(6,2).

[0131] Preferably, in the case of W (t+1) >W (t) and E (t+1) >E (t) and the PTAG of the t time is FALSE, it is proved that the edge user number distribution expansion has occurred for two consecutive times, and the mobility of the edge user is also gradually increased, so that the power fast recovery of 2 times can be performed, that is, c=2.

[0132] The embodiment of the application continues to track the first weight and the second weight of the target TA interval at the (t+1) time based on the first weight and the second weight of the target TA interval at the t time without power contraction, and when the first weight at the (t+1) time is greater than the first weight at the t time and the second weight at the (t+1) time is greater than the second weight at the t time, the power at the t time is recovered according to the target step and the second coefficient as the power at the (t+1) time, which can dynamically adjust the cell power according to the distribution state change, the movement state change and the target identification of the edge user at the (t+1) time, and improve the precision of power adjustment.

[0133] On the basis of any of the above embodiments, in the case that the first weight of the target TA interval at the t time is greater than the first weight at the (t-1) time, after the first weight and the second weight of the target TA interval at the (t+1) time are obtained based on the number of users, the corresponding distance value and the number of handover requests of each TA interval at the (t+1) time, the method further comprises: in the case that the first weight of the target TA interval at the (t+1) time is greater than the first weight at the t time, the second weight of the target TA interval at the (t+1) time is less than or equal to the second weight at the t time, and the target identification is the first state, the power of the target cell at the (t+1) time is obtained based on the power of the target cell at the t time and the target step, and the value of the target parameter is updated based on a preset rule.

[0134] Wherein, the power of the target cell at the (t+1) time is greater than the power of the target cell at the t time.

[0135] Specifically, in the case of W (t+1) >W (t) and E (t+1) E (t)If the PTAG of the tth moment is FALSE, it is proved that the edge user number distribution has been expanded for two consecutive moments, but the mobility has not obviously increased, and the 1 times power recovery can be performed, and the expression is:

[0136] Pr (t+1) = Pr (t) +f(δ (t+1) ,k (t+1) )

[0137] The embodiment of the application continues to track the first weight and the second weight of the target TA interval at the (t+1)th moment based on the fact that the power shrinkage is not performed at the tth moment, and when the first weight at the (t+1)th moment is greater than the first weight at the tth moment, and the second weight at the (t+1)th moment is less than or equal to the second weight at the tth moment, the power at the tth moment is recovered again according to the target step as the power at the (t+1)th moment, and the cell power can be dynamically adjusted according to the target step based on the distribution state change and the movement state change of the edge user at the (t+1)th moment and the target identifier, thereby improving the precision of power adjustment.
