Example 1

Fig. 2 is a schematic flow chart of a load balancing method provided in the present application, as shown in fig. 2, where the method includes:

step 201, determining a target NR cell needing load balancing according to the obtained usage information of each NR cell and a measurement report of UE connected to each NR cell;

step 202, determining adjacent 4G cells to the target NR cell, and determining a 4G cell to be balanced in each adjacent 4G cell according to the cell capacity value of each adjacent 4G cell;

step 203, determining the service requirement value of each UE connected to the target NR cell, and determining the UE to be balanced according to each service requirement value;

Step 204, for each UE to be balanced in each UE to be balanced, determining a matching degree between each UE to be balanced and each 4G cell to be balanced, and controlling each UE to be balanced to perform cell switching according to each matching degree.

It should be noted that, the specific implementation body of the load balancing method provided in the present application is a cell load balancing device, and the cell load balancing device may be integrated or installed or carried in the foregoing server 1.

Specifically, in step 201, firstly, the network management platform and the base station upload the NR cell usage information and the measurement report to the server in a real-time or periodic manner, so that the load balancing device obtains the NR cell related information from the server and performs corresponding processing.

Acquiring using information and a measurement report of each NR cell from a server at a load balancing device, and determining the RB resource block occupancy rate of each NR cell according to the number of resource blocks (total RB resource blocks of the cell) and the number of occupied RBs (resource blocks allocated and used by online users) in the using information of the NR cell; and determining the user occupancy rate of each NR cell according to the maximum number of users (the maximum scale of the cell activation state user number) and the maximum number of users (the actual activation state user number) in the NR cell use information. If the occupancy rate of the RB resource block is higher than a preset occupancy rate threshold of the RB resource block or the occupancy rate of the user is higher than the occupancy rate threshold of the user, the NR cell exceeds the coincidence, and load balancing operation is needed.

The RB resource block occupancy rate threshold and the user occupancy rate threshold are obtained by collecting and analyzing NR cell load conditions based on a big data technology, for example, a reference value may be used as a basis for determining an overload state, but is not limited to this value.

Specifically, step 202, for an NR cell needing load balancing operation, a load balancing device issues a measurement control neighboring 4G cell instruction to a UE end of the NR cell, and obtains signal strength and cell capability values of each neighboring 4G cell, where if the signal strength and cell capability values of each neighboring 4G cell are higher than a preset 4G cell signal threshold and 4G cell capability threshold, the 4G cell may be used as a 4G cell to be balanced.

The measurement control refers to that the UE detects signals of nearby 4G cells, and the detection result is transmitted to the base station through an uploading measurement report and then transmitted to the load balancing device by the base station; the cell capacity value is obtained by the load balancing device through inquiring a mobile network engineering parameter table in the server; the 4G cell signal threshold and the 4G cell capacity threshold are obtained by collecting and analyzing the signal value and the capacity value of the 4G cell in real time based on a big data technology, such as a reference value, and can be used as a minimum threshold of the 4G cell capable of meeting the UE service requirement under an NR cell, but the threshold is not limited to the value.

Specifically, in step 203, according to the signal strength, the service type, the time delay, the rate and the corresponding weight values in the measurement report obtained from the server by the load balancing device, the weight calculation is performed to obtain each service requirement value of each UE in the NR cell. And comparing the service requirement value of each UE with the maximum and minimum thresholds of the UE service of the NR cell, and if the service requirement value of the UE is not greater than or equal to the maximum threshold of the service and not less than or equal to the minimum threshold of the service, taking the service requirement of the UE as a candidate UE to be balanced. The candidate UE also needs to meet the requirements that the energy consumption caused by using an NR cell under the current signal strength, service type, time delay and current rate is larger than the energy consumption caused by using a 4G cell, so that the candidate UE can be the UE to be balanced.

The maximum and minimum thresholds of the UE service are obtained by collecting and analyzing the UE service capacity demand value of the NR cell in real time based on a big data technology, such as an average value, and can be used as a basis for whether the UE service demand value of the NR cell can be balanced or not, but the method is not limited to the value; the energy consumption caused by using an NR cell or a 4G cell under a certain signal intensity, service type, time delay and current speed is also the difference between the two values, namely the energy consumption value of the service, which is obtained by analyzing mass data collected in real time, such as an average value, wherein the value only represents the energy consumption of a certain service to the NR cell and the 4G cell under a certain condition, but is not limited to the type value.

Specifically, in step 204, for each UE to be balanced, a capability difference value between the UE and each 4G cell to be balanced is calculated, a distance value between the UE and each 4G cell to be balanced is calculated, and the capability difference and the distance weight are combined, so as to obtain the matching degree between each UE to be balanced and each 4G cell to be balanced through a weighting operation. And taking the matching degree value as a reference value of the priority, namely, the matching degree value between a certain 4G cell and the UE to be balanced is the largest, arranging the 4G cell at the first position as a target of the first try load of the UE, arranging the 4G cells to be balanced according to the priority, and carrying out load balancing try operation by the UE to be balanced according to the sequence.

By using the cell balancing load method, not only the load of the NR cell can be reduced, but also the energy consumption of the NR cell can be reduced by switching the service of each UE to the adjacent 4G cell.

Embodiment two:

fig. 3 is a flow chart of another load balancing method provided in the present application, as shown in fig. 3, the method includes:

step 301, determining the RB occupancy rate of each NR cell and the user occupancy rate of the NR cell according to the usage information of each NR cell;

step 302, determining an NR cell with an RB occupancy greater than or equal to a preset first occupancy threshold or with a user occupancy greater than a preset second occupancy threshold in the NR cells as the target NR cell.

Specifically, steps 301 and 302 are implemented to determine a specific implementation manner of the target NR cell that needs to perform load balancing according to the acquired usage information of each NR cell and the measurement report of the UE connected to each NR cell.

In step 301, the load balancing device obtains RB occupancy and user occupancy of each NR cell, where the load balancing device obtains usage information of the NR cell step from the server, and then obtains the number of Resource Blocks (RBs), the number of occupied RBs, the number of users, and the maximum number of users in the usage information, thereby obtaining the RB occupancy and the user occupancy of the NR cell in step 301.

In step 302, the load balancing device determines a target NR cell that needs to be load balanced in this time from among the NR cells.

Specifically, before confirming the target NR cell, the load balancing apparatus needs to preset a first occupancy threshold, i.e. an RB occupancy threshold, and a second occupancy threshold, i.e. a user occupancy threshold. The two thresholds are used for collecting and analyzing the occupancy rate of the RBs and the occupancy rate of the users in the usage information of the NR cells through a big data technology, and a certain value is determined as a threshold, such as an average value, and the threshold can only represent that the NR cells are in an overload state, but is not limited to the threshold.

And comparing the RB occupancy rate of each NR cell with the first occupancy rate and the second occupancy rate preset in load balancing, namely when the RB occupancy rate of the NR cell is higher than the first occupancy rate or the user occupancy rate is higher than the second occupancy rate, carrying out balancing load processing on the NR cell, namely taking the NR cell as a target NR cell to be balanced.

Step 303, determining 4G cells adjacent to the target NR cell.

After the load balancing device determines the target NR cell to be balanced, the adjacent 4G cell of the target NR cell needs to be determined.

The 4G cell adjacent to the NR cell refers to a 4G cell having a signal strength that meets the requirement and is connected to the NR cell on the network, and in this embodiment, the determination of the adjacent 4G cell may be performed by the signal strength. For example, the base station apparatus may receive the measured cell signal strengths reported by the UEs, and then select, as the neighboring cells, cells whose strengths satisfy the condition according to the strengths of the 4G cells.

Specifically, a measurement control instruction is issued to the UE in the target NR cell, that is, a 4G cell of a different operator connected to the target NR cell is detected and the measurement report is generated. And forming a 4G cell signal strength set according to the signal strength information of the 4G cells of different operators in the measurement report and according to the data format of 'operators, 4G cells = signal strength values'.

When determining adjacent 4G cells corresponding to the target NR cell, comparing the signal intensity of the 4G cell with the threshold value of the signal intensity of the 4G cell for each cell in the 4G cell signal intensity set, and if the signal intensity of one 4G cell in the set is larger than the signal intensity threshold value of the 4G cell, the 4G cell is included in the 4G cell set adjacent to the NR cell.

That is, step 303 specifically includes receiving a set of signal strengths of 4G cells reported by UEs connected to the target NR cell, where the set of signal strengths of 4G cells includes signal strengths of 4G cells measured by UEs; and according to the 4G cell signal strength set, using the 4G cell with the signal strength larger than the signal strength threshold as a 4G cell adjacent to the target NR cell.

Step 304, obtaining engineering parameter information of each adjacent 4G cell in the adjacent 4G cells, where the engineering parameter information includes: sharing switch value, cell bandwidth, cell downlink PRB utilization rate and cell user number;

after confirming the target NR cell and the adjacent 4G cells, the load balancing device needs to obtain engineering parameter information of each adjacent 4G cell, and in step 304, the load balancing device obtains an engineering parameter table of an operator from a server, where the parameter table includes a cell name, a shared switch value, a cell bandwidth, a cell downlink PRB utilization rate, and a cell user number.

In other words, step 304 includes obtaining engineering parameter information of each neighboring 4G cell of the neighboring 4G cells, where the engineering parameter information includes: sharing switch value, cell bandwidth, cell downlink PRB utilization and cell user number.

Specifically, the shared value switch refers to a switch capable of mutually transferring the use functions among different operators, for example, the switch is opened, and the service of the UE can be switched and transferred or alternatively completed under different operator networks; cell broadband refers to a general broadband access mode, and fiber-to-cell, namely LAN broadband, provides shared bandwidth for the whole building or cell; the utilization rate of the cell downlink PRB is the difficulty of reaction scheduling, is related to user behaviors, and is higher when the number of users is excessive.

And by acquiring engineering parameter information of each adjacent 4G cell, the load balancing device is facilitated to comprehensively evaluate each adjacent 4G cell, and subsequent processing is facilitated.

And 305, weighting the engineering parameter information of each adjacent 4G cell to obtain a cell capacity value of each adjacent 4G cell, and taking the adjacent 4G cell with the cell capacity value larger than a preset capacity value threshold as the 4G cell to be balanced.

After the load balancing device obtains the engineering parameter table of each adjacent 4G cell, the capacity value of each adjacent 4G cell needs to be confirmed, and then the 4G cell to be balanced is confirmed, in step 305, the load balancing device obtains the capacity value of each adjacent 4G cell through the engineering parameter table of each adjacent 4G cell obtained by the server, the capacity value refers to the capacity of the 4G cell for processing the service of the UE, and the 4G cell to be balanced is confirmed according to the comparison result of the capacity value of each 4G cell and the capacity value threshold of the 4G cell preset by the load balancing.

Specifically, the capacity value of each adjacent 4G cell is obtained by sharing the switch value, the cell bandwidth, the cell downlink PRB utilization rate, the number of cell users and the weight value used for the cell users in the statistical parameter table and then carrying out weighting treatment on the cell users. Before that, the load balancing device presets a 4G cell capacity value threshold, the threshold is based on big data means, capacity values of all 4G cells and the lowest network capacity value meeting the service requirement of 5G users are obtained through a terminal, the capacity values of the 4G cells and the lowest network capacity value required by the NR cell service are comprehensively compared, the collected data of the service requirement of the 5G users are averaged, then the average value is compared with the capacity values of the 4G cells, and if the capacity values of the 4G cells are generally larger than the average value, the average value is used as the capacity value threshold; if the capability value of the 4G cell is generally smaller than the average value, the capability value of the 4G cell higher than the average value is calculated, and the capability value of the 4G cell is the capability value threshold. The value can be used as whether the adjacent 4G cells can carry out load balancing operation under the NR cells, and the efficiency of the subsequent steps can be improved.

Further, the capability value of the neighboring 4G cell is compared with a preset capability value threshold, and if the capability value of a certain neighboring 4G cell is higher than the preset capability value threshold, the neighboring 4G cell can be used as the 4G cell to be balanced.

That is, step 305 includes taking engineering parameter information for each of the neighboring 4G cells, wherein the engineering parameter information includes: sharing switch value, cell bandwidth, cell downlink PRB utilization rate and cell user number; weighting the engineering parameter information of each adjacent 4G cell to obtain a cell capacity value of each adjacent 4G cell; and taking the adjacent 4G cells with the cell capacity values larger than a preset capacity value threshold as the 4G cells to be balanced.

Step 306, for each UE to be balanced in each UE to be balanced, determining a matching degree between each UE to be balanced and each 4G cell to be balanced, and controlling each UE to be balanced to perform cell switching according to each matching degree.

In step 306, the load balancing apparatus needs to perform one-to-one matching on each UE to be balanced and each 4G cell to be balanced, so as to control each UE to be balanced to perform cell switching.

In the matching process, the load balancing device firstly determines the matching degree between each UE to be balanced and each 4G cell to be balanced.

Specifically, the load balancing device selects one of the UEs to be balanced from the UEs to be balanced as a target UE, calculates a difference between a cell capacity value of each 4G cell to be balanced and a service requirement value of the target UE, calculates a distance between each 4G cell to be balanced and the target UE, and finally performs a weighted operation on the difference and the distance between each 4G cell to be balanced and the target UE to obtain a matching degree between each 4G cell to be balanced and the target UE.

Further, the matching degree between the 4G cell to be balanced and the target UE is related to the service capability requirement value of each UE to be balanced, the capability value of each 4G cell to be balanced, the distance value between the user of each UE to be balanced and each 4G cell to be balanced, the weight corresponding to the parameters, and the like.

Wherein, the distance value between the user of each UE to be balanced and each 4G cell to be balanced is to input the longitude and latitude information of the user in the NR cell measurement report into a distance formula

D(N _x L _n )＝R·arc cos[cos(lat _Nx )*cos(lat _Ln )*2*cos(lon _Nx -lon _Ln )+

sin(lat _Nx )sin(lat _Ln )]，(lon _Nx ,lat _Nx )

Wherein x represents a terminal number, (lon _Ln ,lat _Ln ) And the longitude and latitude reported by the terminal are represented by N, wherein N represents the terminal sequence number, and N represents the service requirement value of each UE in the NR cell.

In order to obtain the matching degree between each 4G cell to be balanced and the target UE, firstly, obtaining the capability difference between each UE to be balanced and the 4G cell, then, obtaining the distance value between the user of each UE to be balanced and each 4G cell to be balanced according to a distance formula, and finally, summing the obtained capability difference and the distance value with the corresponding weight product.

After the calculation of the matching degree between the target UE and each to-be-balanced 4G cell is completed, the load balancing device selects the next to-be-balanced UE from each to-be-balanced UE as the target UE, and executes the calculation process to obtain the matching degree between the next to-be-balanced UE and each to-be-balanced 4G cell.

And repeating the process until the matching degree between each UE to be balanced and each 4G cell to be balanced is obtained.

Table 1 shows a schematic representation of the degree of matching between each UE to be balanced and each 4G cell to be balanced.

TABLE 1

As shown in Table 1, N _x Representing target UE to be balanced under target NR cell, x represents terminal sequence number, L _n Representing the set of 4G cells to be equalized, n representing the cell number.

For N in Table 1 ₁ The target UE to be balanced is connected with each 4G cell to be balanced, namely with L ₁ 、L ₂ 、L ₃ The matching degree between the two parts is respectively 1.57, 0.57 and 2.57.N (N) ₂ Between each 4G cell to be balanced, namely L ₁ 、L ₂ 、L ₃ The matching degree values are respectively 0, 1.01 and 0.01; n (N) ₃ Between each 4G cell to be balanced, namely L ₁ 、L ₂ 、L ₃ The matching degree values are respectively 0.25, 0 and 1.25.

In order to realize the switching control of the UE to be balanced, the load balancing device also selects a target 4G cell meeting the cell switching condition of the target UE from the 4G cells to be balanced.

Namely, according to the difference value between the cell capacity value of each 4G cell to be balanced and the service requirement value of the target UE and the distance between each 4G cell to be balanced and the target UE, selecting a target 4G cell meeting the cell switching condition of the target UE from each 4G cell to be balanced.

As L in Table 1 ₂ 、L ₃ Can be used as N ₂ Is a target 4G cell of (c).

The load balancing firstly obtains the capacity values of the cells through a mobile network engineering information table, and L is defined as _n Capacity value of (n=1, 2, 3) and N to be equalized ₂ Difference, i.e. L ₁ -N ₂ ＝0、L ₂ -N ₂ >0、L ₃ -N ₂ >0 due to L ₂ 、L ₃ Capability value of (2) is higher than N ₂ The required capacity value is L ₂ 、L ₃ As a candidate target 4G cell, the subsequent processing is continued. The load balancing device calculates a distance value D (N) between each UE to be balanced and a candidate target 4G cell according to the longitude and latitude of the user of the UE to be balanced _x L _n ) D (N) ₂ L ₂ )<D _th 、D(N ₂ L ₃ )＝D _th Due to N to be equalized ₂ Distance L ₂ 、L ₃ Less than or equal to a distance threshold D preset by load balancing _th Then the candidate target 4G cell L ₂ 、L ₃ Becoming target 4G cell L ₂ 、L ₃ 。

Then, the load balancing device prioritizes the target 4G cell and issues the handover control parameters to the target UE, so that the target UE performs handover.

Specifically, the handover control parameters include the priority of each target 4G cell, the maximum number of times of attempted handover, and the maximum handover time.

When the target UE receives the handover control parameter, it will select the target 4G cell with the highest priority (i.e. highest matching degree) according to the priority of the target 4G cell, so as to attempt handover to the target 4G cell.

In the handover process, in order to improve the handover efficiency, for each target 4G cell, the target UE performs a handover operation according to the number of attempted handovers carried in the handover control parameter and the maximum handover time, that is, when the number of handovers performed by the target UE to a certain target 4G cell is equal to the number of attempted handovers, or when the time for performing handover by the target UE to a certain target 4G cell is equal to the maximum handover time, the target UE stops the handover to the target 4G cell, and selects, according to the priority of the target 4G cell, the target 4G cell with the highest priority (i.e., the highest matching degree) from among the target 4G cells that do not attempt to perform handover, so as to try handover again.

And repeating the above process until the target UE completes the switching.

As in table 1, load balancing pair-band balancing N ₂ For L ₂ 、L ₃ The target 4G cell is prioritized, and the priority sequence is L ₂ 、L ₂ Then load balancing issues control parameter maximum switching times X to the terminal to be balanced _th =3, and maximum switching time T _th ＝30ms，N ₂ Firstly, selecting a target 4G cell L with highest priority ₂ Attempting handover, N ₂ An own timer T and an own number of times of trial equalization X counter, wherein the accumulated trial time is 30ms and the number of times of trial switching is 1, N ₂ Has reached the maximum switching time for L ₂ Attempt handover failure, then N ₂ Attempting to get to the next higher priority target 4G cell L ₃ An attempt is made, and the own timer T and the own number of attempts to equalize are set to X counter 0, and N is the number of times of trial switching 2 and 25ms are counted up in the present attempt ₂ For L ₃ Success of the attempt

In other alternative embodiments, the switching efficiency is further improved. For the load balancing device, a total time threshold and a total time threshold of the handover may be configured for each target UE, so that, in the handover process of any one target UE, the load balancing device controls the any one target UE to stop the load balancing process when the total time of the handover reaches the time threshold or the total time of the handover reaches the time threshold.

Specifically, the load balancing device will first determine the total number of times and total time for the target UE to perform handover to all target 4G cells according to the handover control parameters; the total times and the total time may be actively reported to the load balancing device by the UE.

The load balancing device will perform the following decisions on the total number of times and total time of the target UE: if the number of times is greater than or equal to a number of times threshold, or if the total time is greater than or equal to a time threshold, the handover to the target UE fails, and a next target UE is determined in the UEs to be equalized.

Meanwhile, the load balancing device controls the next target UE to execute cell switching according to the matching degree between the next target UE and each 4G cell to be balanced until the cell switching of all the target UEs is completed.

As in table 1, load balancing pair-band balancing N ₂ For L ₂ 、L ₃ In the load balancing attempt of the target 4G cell, the total attempt time is 55ms, the total attempt times is 3 times, the total time threshold and the total time threshold are set to be 5min and 10 times, and N is to be balanced ₂ The total try time and try times are not higher than the total times threshold value and the total time threshold value, N is to be balanced ₂ If there are further switchable 4G target cells, a handover attempt may be continued for the next target 4G cell.

Finally, when the load balancing completes the cell handover of all the target UEs, performance detection needs to be performed again on each target NR cell, in this embodiment, the cell of the UE that is successfully handed over is exemplarily performed, step 301 in this embodiment is performed, and after the completion of the handover, the RB occupancy rate and the user occupancy rate of the cell are confirmed and compared with corresponding thresholds, and if the RB occupancy rate and the user occupancy rate are smaller than the thresholds, the handover is considered to be successful.

In this embodiment, a target NR cell that needs to perform load balancing is determined by acquiring usage information of each NR cell and a measurement report of a UE connected to each NR cell; determining 4G cells adjacent to the target NR cell, and determining a 4G cell to be balanced in each adjacent 4G cell according to the cell capacity value of each adjacent 4G cell; determining service demand values of all UE connected into the target NR cell, and determining UE to be balanced according to the service demand values; and determining the matching degree between each UE to be balanced and each 4G cell to be balanced according to each UE to be balanced in each UE to be balanced, and controlling each UE to be balanced to execute cell switching according to each matching degree. The method provided by the application has better energy-saving effect and lower input cost for the part period or carrier wave flexible switching-off according to the cell load so as to save energy by adding hardware infrastructure in the prior art.
