Description
Technical Field

Background
With the issuing of 5G commercial license plates to telecom operators by the letter department, 5G base station construction is started in each metropolitan area of China, and D frequency bands 2575-2635 MHz used currently are required to be reshuffled to 2615-2675 MHz in China according to the frequency use requirement of the letter department, so that D1 and D2 frequency point resources are required to be vacated.
The scheme of D frequency band vacation at present is to supplement the D frequency point cell of the retirement frequency with FDD1800 or 3DMIMO cell, and the specific scheme is as follows: for a single-layer network D frequency band cell, FDD1800 is directly used for replacement; for D frequency band cells in the multi-layer network, if FDD1800 is not used in the same sector, the D frequency band cells are directly replaced by the FDD1800, and if the used FDD1800 is replaced by the D frequency band cells by 3 DMIMO.
The existing D frequency band frequency-withdrawal scheme can directly and simply replace all D frequency band cells, and equipment resources and labor are wasted. The sector-level traffic is not analyzed under the multi-layer network configuration, whether other cells in the same sector have the capacity to absorb the traffic after the D-band cell is disconnected is not accurately evaluated, and FDD1800 or 3DMIMO equipment is not needed to be supplemented for the multi-layer network sector having the capacity to absorb the traffic. D frequency band cell equipment is replaced in a large quantity and large in scale, so that the construction period time is prolonged, the overall D frequency band network-quitting progress is not facilitated, the long-time influence on the existing LTE network is caused, and the use perception of a user is not facilitated. Meanwhile, whether capacity supplement after frequency withdrawal of the D frequency band can meet customer perception requirements is not evaluated, which can cause high load of partial cells; for the high-load cell existing before the frequency withdrawal of the D frequency band, the problem of customer perception is solved by combining the frequency withdrawal capacity supplement of the D frequency band in one time, so that the old problem in the capacity aspect after the frequency withdrawal of the D frequency band is not solved, and the new problem appears.

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flow chart of a frequency back-off method based on capacity estimation according to an embodiment of the present invention. The frequency-back method based on capacity evaluation is applied to an operator server side, and as shown in fig. 1, the frequency-back method based on capacity evaluation comprises the following steps:
step S11: and acquiring index data and network management configuration data, and calculating a first sector topological structure of the multi-layer network according to the network management configuration data.
Specifically, as shown in table 1, indexes including cell traffic, utilization rate of physical resource blocks (physical resource block, PRB), user perception rate and the like are extracted from an index acquisition platform, and the acquisition time period is a continuous one-month-hour index. The afternoon experience rate in table 1 is the user perceived rate.
TABLE 1 index data
In the embodiment of the invention, network management configuration data, namely cell configuration data, is collected from the network management, wherein the cell configuration data comprises cell names, frequency points, bandwidths and the like, and the cell topology structure in the multilayer network is extracted from the network management. Table 2 is cell configuration data collected in network management of each manufacturer, including data such as base station name, cell name, base station number, sector number (id), working frequency band, coverage scenario, bandwidth, etc.
Table 2 network management configuration data
Further, a first sector topology of the multi-layer network is calculated according to the collected cell configuration data, and table 3 is an example of the obtained first sector topology. Specifically, according to cell configuration data, cell compositions including D frequency band cells of different physical sectors of each base station are counted to form a first sector topological structure.
Table 3 first sector topology
Step S12: and acquiring the first limit flow of the multi-layer network sector and the self-busy time flow of the multi-layer network sector according to the index data and the sector topological structure.
In the embodiment of the invention, the second limit flow of each cell is obtained according to the index data. The index data at least comprises cell flow, physical resource block utilization rate and user perception rate, and a perception rate inflection point is determined according to the physical resource block utilization rate and the user perception rate; and obtaining the cell flow corresponding to the sensing rate inflection point to obtain the second limit flow of the cell. Specifically, according to the traffic of the cell, the PRB utilization rate and the user perception rate, the corresponding cell PRB utilization rate is found under the premise that the influence of the user perception rate is not obvious, then the corresponding limit traffic is found, the frequency division and the bandwidth division are carried out, and the limit traffic of various cells is counted. As shown in fig. 2, taking the perceived rate inflection point and the corresponding flow calculation under the 15M bandwidth of the FDD1800 cell as an example, it can be seen from fig. 2 that the perceived rate decreases most rapidly when the PRB utilization is 50%, so that 50% of the PRB utilization is the perceived rate inflection point, and it can be seen from table look-up 4 that the flow corresponding to the perceived rate inflection point is 4.03GB, so that the limit flow of the FDD1800 cell is 4.03GB, and this is the second limit flow.

In the embodiment of the invention, after the second limit flow of each frequency band cell is obtained, the first limit flow of the multi-layer network sector after the D frequency band cell is disconnected is calculated according to the second limit flow of each cell and the first sector topological structure. Specifically, in a multi-layer network sector containing a D frequency band cell, calculating a second sector topological structure of the D frequency band cell after the network is removed according to the first sector topological structure; and summing the second limit flow of each cell according to the second sector topological structure after the D-band cell is disconnected, and obtaining the first limit flow of the multi-layer network sector after the D-band cell is disconnected. The second sector topology is a sector topology obtained by subtracting the D band cell from the first sector topology. And summing the second limit flow of each cell of the sector according to the second sector topological structure to obtain the first limit flow of the subtracted multilayer network sector.
The following are illustrated: the method comprises the steps of setting a sector number 14384_2 of a 2-sector under an SJQID0515-HLHD base station, wherein the topology structure of a first sector of the sector is 1D+1F+1FDD1800+1FDD900+0A, and the topology structure of a second sector of the corresponding D-band cell after the cell is off-line is 1F+1FDD1800+1FDD900+0A. From the second limiting flows of the frequency band cells shown in table 5, the first limiting flow=3.58 (F-20) +4.03 (FDD 1800-15) +1.5 (FDD 900-15) =9.11 GB of the multi-layer network sector after the D frequency band cell is disconnected is calculated.
In the embodiment of the invention, the self-busy hour traffic of the multi-layer network sector is also obtained according to the index data and the network management configuration data. Extracting the self-busy hour traffic of cells which are continuous for one month, and finding out the maximum self-busy hour traffic of the cells; summing the maximum self-busy hour traffic of each cell according to the first sector topological structure to obtain the self-busy hour traffic of the sector; for the sector containing the senior member (very important person, vip) cell, multiplying the self-busy hour traffic of the sector by a preset coefficient to obtain the final self-busy hour traffic of the multi-layer network sector. Specifically, the most busy traffic of each cell is found in the continuous 1 month-level traffic, the sector-level self-busy traffic is calculated according to the addition of the most busy traffic of each cell in the first sector topology of the multi-layer network, and for the sector containing vip cells, the sector self-busy traffic is multiplied by a preset coefficient. The preset coefficient in the embodiment of the present invention is preferably 1.2.
The following illustrates multi-layer network sector self-busy traffic calculation: physical sector 23489-0 contains a total of 5 cells, each of which is screened for self-busy traffic for 1 month in succession, see table 6 below.
TABLE 6 self-busy hour traffic for each cell for 1 month in succession
As can be seen from table 6, the self-busy traffic of sector 23489-0 is the sum of the self-busy traffic of the 5 cells: 0.58+3.29+7.12+1.33+0.89=13.21 GB. Since the FDD1800 cell in the sector belongs to the vip cell, the sector needs to be multiplied by a preset coefficient of 1.2 to obtain the self-busy traffic of the multi-layer network sector finally: 13.21 x 1.2=15.85 GB.
Step S13: and calculating the traffic allowance of the multi-layer network sector by taking the difference between the first limit traffic and the self-busy traffic of the multi-layer network sector.
In the embodiment of the present invention, the multi-layer network sector traffic margin=the first limit traffic of the multi-layer network sector-the multi-layer network sector self-busy traffic. If the self-busy traffic of the multi-layer network sector is denoted by a and the limit traffic of the multi-layer network sector is denoted by B, it is known from step S12 that for the multi-layer network sector including the vip base station of the vip cell, the first limit traffic is 1.2A and the corresponding multi-layer network sector traffic margin is B-1.2A. For the multi-layer network sector of the common base station, the first limit flow is A, and the corresponding multi-layer network sector flow allowance is B-A.
Step S14: and D frequency band frequency rejection and capacity supplement are carried out according to the sector flow allowance of the multi-layer network.
In the embodiment of the invention, the capacity supplement scheme is determined according to the multi-layer network sector flow allowance and the D-band cell detail list. If the traffic margin of the multi-layer network sector is larger than 0, the multi-layer network sector is capable of absorbing the user traffic and guaranteeing the user perception after the D cell is disconnected, and the multi-layer network sector after the D frequency band is disconnected is determined not to need capacity supplement. If the traffic allowance of the multi-layer network sector is not more than 0, indicating that the multi-layer network sector has insufficient capacity to absorb the user traffic after the D cell is disconnected, supplementing the multi-layer network sector after the D frequency band is disconnected with FDD1800 or 3DMIMO according to the capacity supplementing rule. Specifically, if the multi-layer network sector after the D-band frequency-withdrawal does not have the FDD1800, the FDD1800 is preferentially supplemented; if the multi-layer network sector after the D frequency band frequency withdrawal has FDD1800, 3DMIMO is supplemented.
More detailed capacity augmentation rules are shown in fig. 3, where a represents the self-busy traffic of the multi-layer network sector, B represents the limit traffic of the multi-layer network sector, and for the multi-layer network sector including the vip base station of the vip cell, if the multi-layer network sector traffic margin B-1.2a >0, the multi-layer network sector has the capability of absorbing user traffic and guaranteeing user perception after the D cell is off-line, and the direct D frequency band is ended after the off-line, without capacity augmentation. If B-1.2A is less than or equal to 0, the multi-layer network sector has insufficient capacity to absorb user traffic after the D cell is disconnected, and capacity supplement is needed. When capacity is supplemented, if the multi-layer network sector after the D frequency band frequency withdrawal has FDD1800, the 3DMIMO is reversely opened, namely the 3DMIMO is supplemented. If the multi-layer network sector after the D frequency band frequency withdrawal does not have the FDD1800, the newly built FDD1800 performs capacity supplement. After the addition of the FDD1800, the added multi-layer network sector flow allowance is further judged, and B+F-1.2A is calculated, wherein F represents the added capacity of the FDD 1800. If B+F-1.2A >0, the multi-layer network sector after capacity supplementation has the capability of absorbing user traffic and guaranteeing user perception after the D cell is disconnected, capacity supplementation is completed, and the method is ended. If B+F-1.2A is less than or equal to 0, the multi-layer network sector after capacity supplementation still has insufficient capacity to absorb user traffic after the D cell is disconnected, and the capacity supplementation needs to be continued, and at the moment, 3DMIMO is reversely opened, namely 3DMIMO is supplemented.
For the multi-layer network sector of the common base station without the vip cell, if the flow allowance B-A of the multi-layer network sector is more than 0, the multi-layer network sector has the capability of absorbing the user flow after the D cell is disconnected and guaranteeing the user perception, and the direct D frequency band is terminated after the frequency disconnection, and capacity supplement is not needed. If B-A is less than or equal to 0, the multi-layer network sector has insufficient capacity to absorb user traffic after the D cell is disconnected, and capacity supplement is needed. When capacity is supplemented, if the multi-layer network sector after the D frequency band frequency withdrawal has FDD1800, the 3DMIMO is reversely opened, namely the 3DMIMO is supplemented. If the multi-layer network sector after the D frequency band frequency withdrawal does not have the FDD1800, the newly built FDD1800 performs capacity supplement. After the addition of the FDD1800, the added multi-layer network sector flow allowance is further judged, and B+F-A is calculated, wherein F represents the added capacity of the FDD 1800. If B+F-A text> 0, the sector of the multi-layer network after capacity supplement has the capability of absorbing user traffic and guaranteeing user perception after the D cell leaves the network, the capacity supplement is finished. If B+F-A is less than or equal to 0, the multi-layer network sector after capacity supplement still has insufficient capacity to absorb user traffic after the D cell is disconnected, and the capacity supplement needs to be continued, and at the moment, 3DMIMO is reversely opened, namely 3DMIMO is supplemented. Thus, the frequency band-D cell frequency-withdrawal and capacity supplement are completed.
The complete frequency-back method based on capacity assessment in the embodiment of the invention is shown in fig. 4, and index data such as cell flow, PRB utilization rate, user perception rate and the like are acquired from an index acquisition platform, wherein the acquisition time period is continuous one month and hour index. Meanwhile, cell configuration data are collected from the network manager, and multi-layer network cell topology is counted according to the collected cell configuration, wherein the multi-layer network cell topology is the first sector topology structure.
And carrying out cell limit flow calculation according to the flow index and the cell configuration: according to the cell flow, the PRB utilization rate and the user perception rate, the corresponding cell PRB utilization rate is found under the premise that the influence of the user perception rate is not obvious, then the corresponding limit flow is found, the frequency division and the bandwidth division are carried out, the limit flow of each cell is counted, and the second limit flow of the cell is obtained.
And calculating the multi-layer network limit flow according to the cell limit flow and the multi-layer cell topology: and in all the multi-layer network sectors containing D, calculating the topology of the multi-layer network sectors after the D is subtracted, namely a second sector topology structure, according to the topology of the multi-layer network cells, and calculating the flow limit of the multi-layer network sectors after the D is subtracted, namely the first limit flow of the multi-layer network sectors after the D frequency band cells are removed from the network by utilizing the calculated cell limit flow.
And calculating the traffic of the sector in the self busy hour according to the traffic index and the multi-layer network sector topology: extracting the self-busy hour traffic of cells for one month continuously, finding out the self-busy hour maximum traffic of the cells, summing the self-busy hour maximum traffic of the cells according to a second sector topological structure, calculating the self-busy hour traffic of the sectors, multiplying the self-busy hour maximum traffic of the cells by 1.2 coefficients on the basis of the important vip sector traffic by taking the guarantee requirements of users of partial vip cells and key scene cells into consideration, and taking the guarantee requirements as the final value of the self-busy hour traffic of the vip sectors.
Calculating sector flow allowance according to the multi-layer network limit flow and the sector self-busy hour flow: and subtracting the self-busy traffic of the sector by using the calculated multi-layer network limit traffic after the D is subtracted, wherein the difference is the traffic allowance of the multi-layer network sector, and the parameter indicates how much traffic can still be absorbed by the sector after the D cell leaves the network and does not influence the perception of the user.
Determining a capacity supplement scheme according to the sector flow allowance and the D-band cell detail list: if the sector traffic margin is positive, the sector has the capability of absorbing the user traffic and guaranteeing the user perception after the D cell is disconnected, so that the FDD1800 or 3DMIMO does not need to be supplemented. If the sector traffic margin is negative, it indicates that the sector has insufficient capacity to absorb user traffic after the D cell is off-line, and it is necessary to supplement FDD1800 or 3DMIMO. The priority of supplementing the new cell is to supplement FDD1800 preferentially if FDD1800 is not used and supplement 3d mimo if FDD1800 is used in the topology of the multi-layer network sector. The more detailed capacity augmentation rules are referred to in fig. 3 above and will not be described in detail here.
The embodiment of the invention is used for 4G frequency withdrawal in 5G construction based on capacity evaluation, calculates the limit flow empirical value of the multi-layer network sector by calculating the empirical value of the limit flow of the cells in different frequency bands without influencing the user perception, compares the empirical value with the actual maximum flow of the current network sector, and calculates whether the sector has enough capacity to absorb the flow of the cell in the D frequency band, thereby making a more accurate capacity supplement scheme, achieving the purposes of reasonably utilizing the current network resource and realizing cost reduction and efficiency enhancement. Through the sector-level flow capacity and user perception guarantee which are comprehensively considered. The FDD1800 or 3D mimo device is not supplemented by a multi-layer network sector capable of absorbing D-band cell traffic. The method effectively saves equipment resources and labor cost, can effectively reduce supplement scale, shortens construction period and reduces influence on an LTE network. The method for calculating the cell limit flow and the method for calculating the sector flow allowance can rapidly and accurately judge whether the sector needs to be supplemented or not, and has strong practicability.
According to the embodiment of the invention, the first sector topological structure of the multi-layer network is calculated according to the network management configuration data by collecting index data and the network management configuration data; acquiring a first limit flow of a multi-layer network sector and a self-busy time flow of the multi-layer network sector according to the index data and the sector topological structure; calculating a multi-layer network sector flow allowance by taking the difference between the first limit flow and the self-busy time flow of the multi-layer network sector; d frequency band frequency rejection and capacity supplement are carried out according to the multi-layer network sector flow allowance, whether sectors need to be supplemented or not can be rapidly and accurately judged, equipment resources and labor cost are effectively saved, supplement scale can be effectively reduced, construction period is shortened, influence on an LTE network is reduced, and practicability is high.
