In the existing LTE (Long Term Evolution ) network, capacity expansion can be performed by a new station or sector splitting manner, and the overlapping coverage ratio of two split cells is greater than that of a common cell. When the LTE network adopts the same-frequency networking mode and the MBB card (communication card only providing data service and not providing voice service) users in the cell have more occupation ratio, each MBB user occupying large bandwidth generates larger inter-cell interference to users in the neighboring cell, particularly to cell edge users, in the overlapped coverage area after the sector splitting, so that the cell edge users keep low throughput rate.
In the prior art, the problem of low throughput rate of cell edge users can be solved to a certain extent by replacing high-power RRUs (remote radio units), newly-built sites, newly-added sectors and the like, but the downlink coverage performance is enhanced by replacing the high-power RRUs, but for a sector splitting scene, the uplink data of the cell edge users is influenced because the users with large bandwidths occupy RB (Resource Block) resources in the overlapping coverage areas.

and optimizing physical resource blocks corresponding to strong signal users and edge users in the first cell and the second cell according to the physical resource block intervals corresponding to the first cell and the second cell.
Referring to fig. 2, the present invention provides a communication method, in a first embodiment of the communication method, comprising the steps of:
step S10, historical communication data of each cell is obtained, and a first cell and a second cell with signal interference are determined according to the historical communication data, wherein the first cell and the second cell both adopt a sector splitting technology;
at present, the CMPAK of China communication group Xin Mba family company has three frequency spectrum resources of 3GPP Band 8 (with the frequency Band of 900 MHz), band 3 (with the frequency Band of 1800 MHz) and Band 1 (with the frequency Band of 2100 MHz), and at present, 2, 3 and 4G networks are all FDD (frequency division duplex) systems. The CMPAK mainly operates an LTE network in Band 3 frequency Band, and since no TDD (time division duplex) spectrum is issued in pakistan, the Band 3 spectrum acquired at present can support one 20MHz LTE carrier in a partial area, and other areas can only support one 15MHz LTE carrier, so that spectrum resources are very limited. And because the CMPAK has more 4G users, more cells with high utilization rate exist in the existing LTE network, and the PRB utilization rate in the whole network busy hour is kept above 67%. Meanwhile, as no related spectrum resource exists, the network capacity expansion can only be realized by a mode of newly built stations or sector splitting. When the capacity is expanded in a sector splitting mode, the overlapping coverage ratio of two split cells is larger than that of a common cell, and MBB users occupying large bandwidth generate larger inter-cell interference to edge users of adjacent cells, so that the data throughput of the edge users of the adjacent cells is affected.
In the cell with the problems, the data throughput of the MBB user occupying a large bandwidth is good, so that the average indexes such as the average downlink rate of the cell are good, and the problem of low data throughput of the edge user is covered and is not easy to find in the conventional network condition assessment. In this embodiment, the historical communication data may include complaint data of the user, whether to use the sector splitting technology, the MBB user ratio, the edge user ratio, the overlap coverage rate between adjacent cells, the transmission power margin of the user equipment, and the like, so that the historical communication data may be analyzed, and the cells with the above problems may be identified for further optimization.
Referring to fig. 3, in one embodiment, step S10 specifically includes:
step S11, complaint data of each cell is obtained, and a first cell list is constructed according to the complaint data;
the person skilled in the art can obtain complaint data within a preset period of time and set the length of the preset period by himself, for example, complaint data of the last half year, a quarter or a month. The complaint data is a description report of network faults and network use problems which are spontaneously provided by a user according to the use condition of the mobile network. User complaints related to network coverage and low communication rate can be screened out through modes of manual labeling, character recognition and the like, so that cells related to the complaints are constructed into a first cell list for further analysis.
Step S12, selecting a cell adopting a fanning technique from the first cell list, and constructing a second cell list;
step S13, judging whether the overlapping coverage rate between every two cells in the second cell list is larger than a third preset threshold value or not;
MR (Measurement Report) measurement reports of MR sampling points of all cells in the second cell list are acquired first, and the overlapping coverage rate between every two cells is determined by comparing RSRP (Reference Signal Receiving Power, reference signal received power) in the measurement reports. For example: setting the sampling points with the difference value smaller than 6dB as coverage sampling points, acquiring the RSRP > -110dBm of one sampling point in the first cell A, acquiring the RSRP > -113dBm of one sampling point in the second cell B, wherein the absolute value of the difference between the two is 3 and smaller than the preset 6dB, and dividing the sampling points with the difference value of all RSRP smaller than 6dB in the first cell A and the second cell B by the number of the sampling points in the first cell A to obtain the overlapping coverage rate of the first cell A and the second cell B.
Step S14, if the overlapping coverage rate between two cells is larger than a third preset threshold, setting the two cells as associated cells, and judging whether the edge users of the associated cells are larger than a fourth preset threshold;
referring to table 1 for example, sector ID 51065_1 and 51065_3 are respectively subjected to sector splitting; sector ID 51065_1 corresponds to cell IDs 51065_0 and 51065_3 after sector splitting is completed; sector ID 51065_3 corresponds to cell IDs 51065_2 and 51065_5 after sector splitting is completed; assuming that the third preset threshold is 5%; the split cell 51065_0 and the same-sector split cell 51065_3 are found to be associated cells, and similarly, the split cell 51065_2 and the same-sector split cell 51065_5 are found to be associated cells.
Table 1 overlay inspection after sector splitting
In one embodiment, step S13 specifically includes:
acquiring a measurement report of the associated cell, and calculating an overpower ratio (PHR) of a transmitting Power margin (Power Head Room) of User Equipment (UE) in the measurement report, wherein the PHR is smaller than a second preset threshold;
judging whether the overpower proportion is larger than the fourth preset threshold value or not;
and if the overpower ratios corresponding to the associated cells are all larger than the fourth preset threshold, executing step S15, and determining the associated cells as a first cell and a second cell with mutually interfered signals.
PHR is the difference between the transmit power value of the UE and the configured maximum transmit power. The PHR can be used for user transmit power analysis, and theoretically, the better the coverage, the lower the UE transmit power is, the larger the PHR. The PHR is actually the expected power calculated according to parameters such as the path loss, and is not the actual transmission power, so that the PHR may be larger than the actual transmission power, and a negative value may occur. In this embodiment, the second preset threshold is 0, that is, a case where the PHR is negative is identified.
Identifying a first cell and a second cell which need to be optimized through the steps, after step S15, executing step S20, obtaining mobile broadband data of the first cell and the second cell, and respectively generating physical resource block (Physical Radio Bearer) intervals corresponding to the first cell and the second cell according to the mobile broadband data, wherein the physical resource block intervals corresponding to the first cell and the physical resource block intervals corresponding to the second cell are not overlapped;
specifically, those skilled in the art may determine the physical resource block interval according to the mobile data card user, the non-mobile data card user corresponding to the cell, and the flow value and the mobile broadband bandwidth corresponding to each user. Those skilled in the art will appreciate that: the physical resource block interval corresponding to the first cell and the physical resource block interval corresponding to the second cell are not overlapped, and the physical resource block interval corresponding to the first cell and the physical resource block interval corresponding to the second cell are respectively smaller than the total physical resource block of the first cell and the total physical resource block of the second cell.
Step S30, respectively determining strong signal users and edge users in the mobile broadband users of the first cell and the second cell according to the mobile broadband data of the first cell and the second cell;
in one embodiment, the step S30 specifically includes:
judging whether the reference signal receiving power of each user corresponding to the first cell is larger than preset power or not in the first cell and the second cell;
if yes, judging whether the difference value between the reference signal receiving power larger than the preset power and the reference signal receiving power of the second cell is smaller than a first preset threshold value;
if yes, judging the user as a strong signal user;
and determining the users corresponding to the user equipment with the transmission power margin smaller than a second preset threshold value in the first cell and the second cell as edge users.
The preset power and the first preset threshold are set by the person skilled in the art. For example: and judging that the user is a strong signal user in an overlapping coverage area of the first cell A and the second cell B when the receiving power (Reference Signal Receiving Power, RSRP) of the sampling point reference signal in the first cell A is larger than-90 dBm and the absolute value of the difference value of the RSRP of the sampling point RSRP and the RSRP of the second cell B is smaller than 6 dB. And determining the user with the PHR value of the MR sampling point lower than 0 in the second cell B as the cell edge user.
And step S40, optimizing physical resource blocks corresponding to strong signal users and edge users in the first cell and the second cell according to the physical resource block intervals corresponding to the first cell and the second cell.
Specifically, updating the communication of the strong signal user in the first cell to schedule in the physical resource block interval corresponding to the first cell, and updating the communication of the strong signal user in the second cell to schedule in the physical resource block interval corresponding to the second cell;
updating that communication of an edge user in the first cell is not scheduled in the physical resource block interval corresponding to the first cell; updating communication of the edge user in the second cell is not scheduled in the physical resource block interval corresponding to the second cell.
In the invention, the cells which use sector splitting technology, have high overlapping coverage ratio of adjacent cells, large MBB user occupation ratio and large station spacing waiting for optimization are obtained through the identification of the historical communication data of each cell; the method comprises the steps that a physical resource block interval P1 is set for a first cell, strong signal users in an overlapped coverage area in the first cell are indicated to the physical resource block interval P1 for scheduling, and uplink interference is not caused to edge users of a B cell in the overlapped coverage area; meanwhile, a physical resource block interval P2 which is not overlapped with the physical resource block interval P1 is set for the second cell, and strong signal users in the overlapped coverage area in the second cell are indicated to the physical resource block interval P2 for scheduling, so that the uplink interference is not caused to the edge users of the first cell, and the network communication quality is optimized.
Referring to fig. 4, further, based on the first embodiment of the present invention, a second embodiment of the communication method of the present invention is provided, in this embodiment, step S20 of the embodiment, the steps of obtaining mobile broadband data of the first cell and the second cell, and generating physical resource block intervals corresponding to the first cell and the second cell according to the mobile broadband data respectively include the steps of:
step S21, mobile data card users and non-mobile data card users of the first cell and the second cell and flow values corresponding to the users are obtained, the data card flow ratio corresponding to the first cell is calculated, and the data card flow ratio corresponding to the second cell is calculated;
specifically, mobile broadband bandwidths of the first cell and the second cell, mobile data card users, non-mobile data card users and flow values corresponding to the users are obtained, and data card flows of the mobile data card users in the first cell and the second cell are calculated according to the mobile data card users and the flow values corresponding to the mobile data card users;
according to the mobile data card user, the non-mobile data card user and the flow values corresponding to the users, respectively calculating the total flow of the first cell and the second cell;
calculating the data card flow rate ratio corresponding to the first cell according to the data card flow rate and the total flow rate corresponding to the first cell, and calculating the data card flow rate ratio corresponding to the second cell according to the data card flow rate and the total flow rate corresponding to the second cell.
The mobile data card user is a user using the MBB card.
Step S22, obtaining the mobile broadband bandwidths of the first cell and the second cell, calculating the physical resource block interval corresponding to the first cell according to the data card flow rate ratio and the mobile broadband bandwidth corresponding to the first cell, and calculating the physical resource block interval corresponding to the second cell according to the data card flow rate ratio and the mobile broadband bandwidth corresponding to the second cell.
For example: the mobile broadband bandwidth of the first cell A is 20MHz, and the LTE bandwidth required by the first cell A can be calculated according to the data card flow rate ratio of 24 percent as follows:
20MHz*24％＝4.8MHz；
the physical resource block interval P1 is:
p1=100×24% =24, i.e. the physical resource block interval P1 may be set to 24 PRB resources in succession.
Further, based on the first embodiment of the present invention, a third embodiment of the communication method of the present invention is provided, and step S40 further includes:
and acquiring the average throughput rate of the users with the real-time bandwidth larger than the preset bandwidth in the first cell and the second cell and the average throughput rate of the edge users in real time, and adjusting the physical resource block interval according to the average throughput rate of the users with the real-time bandwidth larger than the preset bandwidth and the average throughput rate of the edge users.
If the average throughput of the large bandwidth user is reduced by more than a threshold T2, the physical resource block interval P1 of the first cell is increased, and the physical resource block interval P2 of the second cell is increased, while keeping the physical resource block interval P1 and the physical resource block interval P2 not more than the total number of PRBs of the cells.
