Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can 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 flowchart of a transmission bandwidth setting method according to an embodiment of the present invention. The method is applied in a computing device, such as a server in a communication network. As shown in fig. 1, the method comprises the steps of:
and step 110, determining the single-cell peak bandwidth of the 3D MIMO site.
And the peak bandwidth of a single cell of the 3D MIMO site is the peak bandwidth of the single cell of the 3D MIMO site. Determining the single-cell peak bandwidth of the 3D MIMO site may specifically be: the method comprises the steps that a preset value of single-cell peak bandwidth of a 3D MIMO site is preset in a system, and then the single-cell peak bandwidth of the 3D MIMO site is directly obtained; alternatively, the single-cell peak bandwidth of the 3D MIMO site is determined by calculation.
Specifically, as shown in fig. 2, step 110 includes:
step 111, calculating the peak bandwidth of the TD-LTE base station;
and 112, calculating the single-cell peak bandwidth of the 3D MIMO site according to the peak bandwidth of the TD-LTE base station.
The calculating of the peak bandwidth of the TD-LTE base station specifically includes:
according to the network architecture of the TD-LT E, the total transmission bandwidth requirement of the E-NodeB base station includes several parts of the service data bandwidth requirement of the S1 user plane, the signaling transmission bandwidth requirement of the S1 control plane, the service data bandwidth requirement of the X2 user plane, and the signaling transmission bandwidth requirement of the X2 control plane.
The specific calculation formula is as follows: the total bandwidth requirement of the E-NodeB base station = (S1 user plane bandwidth requirement + X2 user plane bandwidth requirement) × the number of sectors + S1 control plane bandwidth requirement + X2 control plane bandwidth requirement + other overhead bandwidths.
The service data bandwidth requirement of the S1 user plane is related to the cell throughput, and can be represented by (sector throughput multiplied by the number of sectors), and when the peak transmission bandwidth is calculated, the sector throughput is calculated by adopting the peak transmission rate; the service data bandwidth requirement of the X2 user plane is related to the number of users switched simultaneously in the cell and the average data volume to be forwarded by each user; the X2 user plane flow during switching is less, and meanwhile, if the flow moves away from the X2 interface during switching, the S1 interface is not occupied, so that the total S1+ X2 flow is unchanged; the bandwidth requirement of the S1 control plane is about 1Mbps; setting the signaling bandwidth of an X2 interface between one base station and another base station to be about 64kbps, wherein one base station is connected with 16 adjacent base stations by X2, and the bandwidth requirement of an X2 control plane is about 1Mbps flow in total; the other overhead bandwidth is calculated as 5%.
To calculate the peak bandwidth of the base station, the peak rate of a single cell needs to be calculated first. Calculating the peak rate of a single cell, specifically comprising: under the condition that the modulation mode is 64QAM, the number of the single-stream bearing bits of each subframe time slot is as follows: total number of RBs x [ number of subcarriers per RB x (number of symbols in subframe-number of control symbols) -number of RSs ] × modulation order x code rate =71280bit; the number of bits of the single-flow bearer service of each DwPTS time slot is as follows: RB total number x [ number of subcarriers per RB x (number of symbols in DwPTS-number of control symbols) -number of RSs ] × modulation order x code rate =47520bit. Then, when 3:1 timeslot allocation and 2x2MIMO are used, the downlink peak bandwidth of a 20MHz single cell is 104.544Mbps.
Thus, the peak bandwidth of the TD-LTE base station may be calculated according to table 1.
TABLE 1
BBU Total Capacity S1+ X2 user plane traffic S1 control plane flow X2 control plane traffic BBU total bandwidth Bearer Bandwidth (5% overhead)
20MHz cell 104.544 1Mbps 1Mbps 107Mbps 112Mbps
As can be seen from Table 1, when the other overhead bandwidths are calculated according to 5%, the peak bandwidth of the TD-LTE base station is 112Mbps.
In step 112, since the current 3D MIMO station adopts a single-stream pairing mode, and the maximum number of paired layers is 16, the single-cell peak bandwidth of the 3D MIMO station is the peak bandwidth of the TD-LTE base station divided by 2 and multiplied by 16, and the single-cell peak bandwidth of the 3D MIMO station is calculated according to the peak bandwidth of the TD-LTE base station, which further includes: and multiplying the peak bandwidth of the TD-LTE base station by eight to calculate the single-cell peak bandwidth of the 3D MIMO site. For example, when the peak bandwidth of the TD-LTE base station is 112Mbps, the single-cell peak bandwidth of the 3D MIMO site is 112 ÷ 2 × 16=896Mbps. Optionally, a single-cell peak bandwidth of the 3D MIMO site is set to 875Mbps in consideration of a certain pairing overhead and signaling overhead in combination with a current network actual measurement result.
It should be noted that, because there are multiple calculation manners for the peak bandwidth of the TD-LTE base station, and different calculation manners can all obtain different calculation results, in this embodiment, the single-cell peak bandwidth of the 3D MIMO site is 875Mbps.
And step 120, calculating the single-station average bandwidth and the single-station peak bandwidth of the 3D MIMO station according to the single-cell peak bandwidth of the 3D MIMO station.
The single-station average bandwidth is the average transmission bandwidth of a single base station, and the single-station peak bandwidth is the highest transmission bandwidth of the single base station. When the 3D MIMO station is configured as S111 (i.e. three sectors, each sector having one carrier), step 120 specifically includes: multiplying the single-cell peak bandwidth of the 3D MIMO site by twenty percent and then by three to obtain the single-station average bandwidth of the 3D MIMO site through calculation; and multiplying the single-cell peak bandwidth of the 3D MIMO site by three to calculate the single-station peak bandwidth of the 3D MIMO site. That is, the single station average bandwidth is 875mbps 20% =3 525mbps, and the single station peak bandwidth is 875mbps 3= -2.6 gbps.
And step 130, determining the minimum configuration requirement of the transmission bandwidth according to the single-station average bandwidth and the single-station peak bandwidth of the 3D MIMO station.
The minimum configuration requirement of the transmission bandwidth comprises a guaranteed bandwidth and a peak bandwidth. Guaranteed bandwidth, i.e., committed Information Rate (CIR); peak bandwidth, i.e. the highest Information Rate (PIR).
Wherein, step 130 specifically includes: step 131, determining a guaranteed bandwidth according to the single-station average bandwidth of the 3D MIMO station; step 132, determining the peak bandwidth according to the peak bandwidth of a single station of the 3D MIMO station.
Wherein, because the peak bandwidth of a single station of the 3D MIMO station is 2.6Gbps, the PTN access ring is required to support 10GE for transmission coordination of the 3D MIMO station. And the bandwidth of the PTN access layer, the convergence layer and the core layer is converged according to a general macro station network bandwidth planning principle of 4. When the average bandwidth of a single station is 525Mbps and the peak bandwidth of the single station is 2.6Gbps, the transmission overhead is considered at the same time, and the method comprises the following steps: CIR = [525Mbps (1 + 20%) ]/2=315Mbps, PIR =2.6Gbps. As shown in table 2, table 2 is the transmission bandwidth evaluation values of different 3D MIMO stations.
TABLE 2
Figure BDA0002248617420000061
Figure BDA0002248617420000071
In this embodiment, in principle, the CIR is configured according to the core layer planned bandwidth, and the PIR is configured according to the bandwidth of "1 sector peak + other sector mean". However, when the bandwidth is guaranteed to be 100Mbps and the peak bandwidth is 880Mbps, the speed measurement requirement and the user experience of the base station can be met, and: the bandwidth size that each base station can guarantee is CIR, the CIR sum of every base station will not exceed the physical bandwidth of the access ring \ convergence ring; if the base station has no flow or the flow is lower than CIR, and the access \ aggregation ring has spare capacity, other base stations can obtain the bandwidth which is larger than CIR and smaller than PIR. Therefore, in the present embodiment, the minimum transmission bandwidth configuration requires that the CIR/PIR be 100Mbps/880Mbps.
And 140, setting the transmission bandwidth of the to-be-adjusted site according to the lowest configuration requirement of the transmission bandwidth.
The station to be adjusted is a 3D MIMO station with poor actual use effect. Step 140 specifically includes: step 141, judging whether the actual configuration of the transmission bandwidth of the site to be adjusted meets the minimum configuration requirement of the transmission bandwidth; step 142, if yes, no transmission bandwidth setting is carried out; and step 143, if not, performing transmission bandwidth setting on the site to be adjusted according to the minimum configuration requirement of the transmission bandwidth. For example, assuming that the transmission bandwidth of the site to be adjusted actually configures CIR/PIR to be 10Mbps/220Mbps, and the minimum configuration of the transmission bandwidth requires CIR/PIR to be 100Mbps/880Mbps, the CIR of the site to be adjusted is adjusted from 10Mbps to 100Mbps, and the PIR is adjusted from 220Mbps to 880Mbps.
According to the embodiment of the invention, the single-cell peak bandwidth of the 3D MIMO site is determined, the single-station mean bandwidth and the single-station peak bandwidth of the 3D MIMO site are calculated according to the single-cell peak bandwidth of the 3D MIMO site, the minimum configuration requirement of the transmission bandwidth is determined according to the single-station mean bandwidth and the single-station peak bandwidth of the 3D MIMO site, the transmission bandwidth of the site to be adjusted is set according to the minimum configuration requirement of the transmission bandwidth, a reasonable transmission bandwidth configuration value can be given, and the problem that the new 3 Dmimmo technology cannot exert the advantages of the new technology due to the setting problem is avoided.
In some embodiments, the method may further comprise: and 150, determining the station to be adjusted.
As shown in fig. 3, step 150 may specifically include:
step 151, obtaining historical information data of the first station and the second station, wherein the historical information data comprises the number of users, the frequency spectrum utilization rate, the time delay and the sensing rate;
step 152, determining a first curve according to the number of users and the time delay of the first station, and determining a second curve according to the number of users and the time delay of the second station;
step 153, determining a third curve according to the number of users at the first site and the downlink sensing rate, and determining a fourth curve according to the number of users at the second site and the downlink sensing rate;
step 154, determining a fifth curve according to the frequency spectrum utilization rate and the time delay of the first site, and determining a sixth curve according to the frequency spectrum utilization rate and the time delay of the second site;
step 155, determining a seventh curve according to the spectrum utilization rate and the downlink sensing rate of the first site, and determining an eighth curve according to the spectrum utilization rate and the downlink sensing rate of the second site;
and step 156, comparing the first curve with the second curve, comparing the third curve with the fourth curve, comparing the fifth curve with the sixth curve, and comparing the seventh curve with the eighth curve, and determining the station to be adjusted in the first station and the second station according to the comparison result.
The first site and the second site are sites which are randomly selected and do not meet the lowest configuration requirement of transmission bandwidth in actual configuration. For example, two 3D MIMO stations in H city are selected, and the actual configuration of the transmission bandwidth is shown in table 3.
TABLE 3
ENODEBID Actual CIR Actual PIR
Site TC (first site) 7XX475 80Mbps 880Mbps
Site LY (second site) 7XX183 10Mbps 220Mbps
In step 151, historical information data of the first site and the second site is obtained, where the historical information data includes the number of users, the spectrum utilization rate, the time delay, and the sensing rate, that is, the number of users, the spectrum utilization rate, the time delay, and the sensing rate data of the first site are obtained, and the number of users, the spectrum utilization rate, the time delay, and the sensing rate data of the second site are obtained. For example, the number of users, the spectrum utilization rate, the time delay and the sensing rate of the station TC and the station LY are respectively extracted from 30 days in 9 months to 16 days in 10 months.
The first curve and the second curve are both relation curves of time delay on the number of users, the third curve and the fourth curve are both relation curves of downlink sensing speed on the number of users, the fifth curve and the sixth curve are both relation curves of time delay on the frequency spectrum utilization rate, and the seventh curve and the eighth curve are both relation curves of downlink sensing speed on the frequency spectrum utilization rate. Step 156 may specifically be: the first curve and the second curve, the third curve and the fourth curve, the fifth curve and the sixth curve, and the seventh curve and the eighth curve are respectively put into the same graph for comparative analysis. For example, T station represents a first station, L station represents a second station, and as shown in fig. 4a to 4d, the average delay of the first station is significantly lower than that of the second station; with the increase of the number of users, the time delay and the downlink sensing rate of the second station are more obviously deteriorated than those of the first station; the frequency utilization rate of the first station is obviously better than that of the second station; with the increase of the frequency spectrum utilization rate, the time delay and the downlink sensing rate of the first site are better than those of the second site, so that the CIR of the second site is adjusted from 10Mbps to 100Mbps and the PIR is adjusted from 220Mbps to 880Mbps when the second site is determined as the site to be adjusted.
According to the embodiment of the invention, the stations to be adjusted are determined in the first station and the second station according to the comparison result through comparison and analysis in multiple aspects of the number of users, the frequency spectrum utilization rate, the time delay, the sensing rate and the like, so that the transmission bandwidth of the stations to be adjusted is set according to the minimum configuration requirement of the transmission bandwidth, a reasonable transmission bandwidth configuration value can be given, and the problem that the 3Dmimo new technology cannot exert the advantages of the new technology due to the setting problem is avoided.
