Description

A network simulation method and device

technical field

The invention relates to the field of communication technology, in particular to a network simulation method and device.

Background technique

With the growth of data service demand, the construction of mobile communication network has entered a new stage. In order to improve the service quality of wireless networks, it is an important aspect of wireless network work to use network planning results to guide actual network construction and network optimization.

Network planning generally includes steps such as demand analysis for wireless network construction, pre-planning of base station sites, network simulation, and wireless resource parameter planning. Among them, network simulation is one of the core links of network planning, and the accuracy of network simulation directly affects network planning. accuracy. At present, the work involved in network simulation mainly includes determining various parameters of the network, mainly including the following two aspects:

1. Network Coverage Forecast

Network coverage prediction is mainly to determine the received power of cells in the planned network, the signal-to-interference plus noise ratio and other parameters as the network simulation results, and provide a basis for subsequent network establishment and optimization. Figure 1 shows a schematic flow diagram of network coverage prediction, as shown in Figure 1, mainly includes the following steps:

Step 101, select a set number of base stations (selected base stations are called stations) to perform propagation model correction.

In this step 101, the selected base stations are usually base stations that can represent different types of ground objects, that is, base stations located in environments of different types of ground objects are selected.

Step 102, perform coverage prediction based on the corrected propagation model, and adjust base station site and basic cell parameters based on the result of coverage prediction (the adjusted base station site and basic cell parameters are called coverage indicators).

In this step 102, the result of coverage prediction generally includes information such as public channel coverage level, SINR probability distribution, service channel coverage level, SINR probability distribution, etc.; based on the result of coverage prediction, adjust the base station site and the basic configuration of the cell, that is, adjust the base station Quantity, location, cell power configuration (transmission power, channel transmission power offset, etc.), cell antenna configuration (antenna type, height, direction angle, downtilt angle, etc.).

Step 103 , judging whether the coverage index meets the coverage index required by network planning, if yes, execute step 104 , if not, return to step 102 .

Step 104, output the coverage index meeting the network planning requirements.

In this step 104, the output coverage index includes public channel coverage level, SINR probability distribution, service channel coverage level and other information.

So far, the process of network coverage prediction ends.

2. Capacity Forecast

Capacity prediction is mainly to determine the capacity and other parameters of the planned network as the network simulation results, and provide a basis for subsequent network establishment and optimization. Figure 2 shows a schematic flow chart of capacity prediction, as shown in Figure 2, mainly including the following steps:

Step 201, using the type of features represented by the electronic map as a weight parameter to determine the geographical distribution of users.

In this step 201, the geographic distribution of users is determined, that is, the types and numbers of users assigned to areas of different feature types are determined.

Step 202, perform capacity simulation, and adjust cell configuration and coverage parameters based on the result of capacity simulation.

In this step 202, capacity simulation is carried out, that is, the coverage area of each cell is determined using the network coverage prediction result, combined with the user geographical distribution information determined in step 201, the user distribution of each cell is obtained, and the Monte Carlo calculation is performed using the set business model. Carlo simulation; adjust the cell configuration and coverage parameters based on the results of the capacity simulation, that is, adjust the cell capacity configuration (such as carrier configuration, time slot configuration, etc.), and combine the base station site and cell basic configuration adjustment in step 102 to meet the network capacity requirements .

Step 203 , judging whether the capacity index meets the capacity index required by network planning, if yes, execute step 204 , if not, return to step 202 .

Step 204, outputting a capacity index meeting the network planning requirement.

In this step 204, the output capacity index includes information such as call loss rate, average downlink throughput of the cell, average uplink throughput of the cell, downlink edge throughput of the cell, and uplink edge throughput of the cell.

At this point, the process of capacity prediction ends.

Through the flow corresponding to Figure 1 and Figure 2, it is possible to determine the network simulation results that meet the network planning requirements, thereby guiding network establishment and optimization. In the actual network establishment and optimization process, it is found that the following problems may exist in the network simulation results determined based on the flow corresponding to Figure 1 and Figure 2:

On the one hand, in the process of network coverage prediction, the propagation model used for network coverage prediction is obtained by correcting the propagation model based on the selected set number of stations. The number of stations is relatively limited, so the propagation module cannot reflect the actual transmission situation of different base stations in the actual network environment, including the propagation difference between base stations, the data propagation difference in different directions and different ground conditions in the coverage area of the base station;

On the other hand, in the process of capacity forecasting, the determination result of the geographical distribution of users depends on the type of features represented by the electronic map. The determination result is only a rough estimate based on the distribution of features, which may be quite different from the actual user distribution. , and the electronic map generally lags behind the actual surface features and its accuracy is limited. Therefore, using the electronic map as a reference factor for capacity prediction may lead to deviations between the capacity prediction results and the actual situation.

Combining the above two problems, the network simulation result determined based on the network simulation process provided by the prior art deviates from the actual network environment, thereby reducing the accuracy of the network simulation result.

In the first embodiment, the network simulation mainly depends on MR (Measure Result, measurement result) data, because MR data is the measurement result to the actual network situation, can reflect the actual network environment, therefore, the determined network is improved by this method. The accuracy of simulation results can better guide network planning.

In the first embodiment, the determined network simulation results mainly include parameters used to characterize the coverage of the planned network and parameters used to characterize the capacity of the planned network; wherein, the parameters used to characterize the coverage of the planned network can be The receiving powers corresponding to each MR reporting point when planning the network, preferably, the parameters used to characterize the coverage of the planning network may further include the SINR (Signal to Interference plus NoiseRatio, signal to interference plus noise ratio); the parameter used to characterize the capacity of the planned network can be specifically the total data rate in the planned network, that is, the throughput rate.

In the first embodiment, MR data needs to be obtained, and the MR data can be obtained from the MR function module of the base station network management system. Specifically, the obtained MR data mainly includes the following content:

1. The received field strength information of the downlink common channel corresponding to each MR report point in the current network (i.e. the current network), wherein the received field strength information of the downlink public channel corresponding to the MR report point is the received power corresponding to the MR report point;

2. Each adjacent cell of the cell where each MR reporting point is located in the current network corresponds to the received field strength information of the downlink common channel, that is, the corresponding receiving power of each adjacent cell of the cell where the MR reporting point is located;

3. The MR data reporting frequency of the cell where the MR reporting point is located, and the MR data reporting frequency of the neighboring cells of the cell where the MR reporting point is located.

In the above MR data, the received power corresponding to the MR report point in the current network is mainly used to determine the corresponding received power of the MR report point when planning the network; the received power corresponding to each adjacent cell of the cell where the MR report point is located is mainly It is used to determine the SINR corresponding to the cell where the MR report point is located when planning the network; the MR data report frequency of the cell where the MR report point is located and the MR data report frequency of the adjacent cell of the cell where the MR report point is located are mainly used to determine the planning network. capacity.

In the first embodiment, after the MR data is obtained, the determined network simulation result needs to be further based on the base station information, that is, the base station information needs to be obtained, and the base station information mainly includes the following contents:

1. Base station latitude and longitude, antenna information (pattern, direction angle, downtilt angle), feeder loss and other information;

2. The base station downlink public channel transmission frequency (that is, the transmission frequency of the base station) information;

3. Information about the transmit power of the downlink common channel of the base station (that is, the transmit power of the base station).

Among the above base station information, information such as the latitude and longitude of the base station, antenna information (direction diagram, direction angle, downtilt angle), feeder loss, and the transmit power of the downlink public channel of the base station (that is, the transmit power of the base station) are mainly used to determine the MR in the current network. The downlink propagation loss corresponding to the cell where the reporting point is located, and determine the corresponding receiving power of the MR reporting point when planning the network.

FIG. 3 shows a schematic flow chart of determining the network simulation result provided by the first embodiment. As shown in FIG. 3 , the process of determining the network simulation result mainly includes the following steps:

Step 301: Determine the received power corresponding to each MR report point in the MR data from the acquired MR data, and determine the base station information corresponding to the cell where each MR report point is located from the acquired base station information.

Step 302: Determine the downlink propagation loss corresponding to the cell where each MR report point is located in the current network according to the received power corresponding to each MR report point and the base station information corresponding to the cell where each MR report point is located.

Step 303: According to the downlink propagation loss corresponding to the cell where each MR reporting point is located in the current network, and the determined link propagation loss difference between the current network and the planned network, determine that each MR reporting point is in the planned The downlink propagation loss corresponding to the cell where the network is located respectively.

Step 304, according to the downlink propagation loss corresponding to the cell where each MR reporting point is located when planning the network and the base station information corresponding to the cell where each MR reporting point is respectively located, determine that each MR reporting point is respectively located when planning the network. corresponding received power.

So far, the process of determining the network simulation result ends. Through the flow corresponding to FIG. 3 , the determined network simulation result is a parameter used to characterize the coverage of the planned network.

In the first embodiment, a preferred implementation of step 302 included in the corresponding process in FIG. 3 is further given. In step 302, it is necessary to determine the downlink propagation loss corresponding to the cell where each MR reporting point in the current network is located. Among them, according to the received power corresponding to the MR report point and the base station information corresponding to the cell where the MR report point is located, the downlink propagation loss corresponding to the cell where the MR report point is located in the current network is determined, which can be based on the link loss calculation model shown in Figure 4 , in this model, P_Tx is the transmit power of the base station, Ga_BS is the antenna gain of the base station, Ga_UE is the antenna gain of the mobile station, Lf_BS is the feeder loss of the base station, PL_DL is the downlink propagation loss corresponding to the cell where the MR reporting point is located, The downlink propagation loss includes spatial propagation loss, building penetration loss, shadow fading, human body loss, and the like. Based on the link loss calculation model shown in Figure 4, it can be determined that the formula for determining the received power P_Rx corresponding to the MR reporting point in the current network is as follows:

P_Rx＝P_Tx+Ga_BS-Lf_BS-PL_DL+Ga_UE Formula (1)

in:

According to the above formula (1), the determination formula of the downlink propagation loss PL_DL1 corresponding to the cell where the MR reporting point is located in the current network can be determined as follows:

PL_DL1＝P_Tx+Ga_BS-Lf_BS-P_Rx+Ga_UE Formula (2)

Wherein, P_Rx is the received power corresponding to the MR reporting point, and the meanings of P_Tx, Ga_BS, Lf_BS and Ga_UE are the same as those in formula (1).

According to formula (2), it can be seen that when determining the downlink propagation loss PL_DL1 corresponding to the cell where the MR report point is located in the current network, you can first determine the base station transmit power P_Tx and antenna The sum of the gains (Ga_BS+Ga_UE), and then use the obtained sum to subtract the received power P_Rx corresponding to the MR report point and the feeder loss Lf_BS included in the base station information, so as to obtain the current network corresponding to the cell where the MR report point is located Downlink propagation loss PL_DL1.

In the first embodiment, the preferred implementation of step 303 included in the corresponding process in Figure 3 is further given. In this step 303, it is necessary to determine the downlink propagation loss corresponding to the cell where each MR reporting point is located when planning the network. , the specific determination process is as follows:

The downlink propagation loss corresponding to the cell where the MR report point is located when the network is planned, the downlink propagation loss corresponding to the cell where the MR report point is located in the current network and the link propagation loss difference between the current network and the planned network Therefore, to determine the downlink propagation loss corresponding to the cell where the MR reporting point is located when planning the network, it is necessary to determine the link propagation loss difference between the current network and the planned network, and the link propagation loss difference can be By comparing the method of model correction to determine the difference in coverage capabilities between the planned network and the current network based on frequency, distance, and ground object conditions. Fig. 5 shows a schematic flow chart of determining the link propagation loss difference between the current network and the planned network. As shown in Fig. 5, the determination process mainly includes the following steps:

Step 501, determine the frequency band currently used by the network through frequency scanning.

Step 502, select a base station site to perform transmission model correction.

In step 502, 3-6 base stations may be selected as stations for transmission model correction, and the selected base stations shall contain as many ground object conditions as possible.

Step 503: Based on the corrected propagation model, measure the path loss of the system under the current network between frequency bands determined by frequency scanning, and predict the path loss of the system under the planned network between frequency bands determined by frequency scanning.

In step 503 , measuring the path loss of the system in each frequency band under the current network and predicting the planned network requires setting the system to work under the same conditions.

Step 504: Filter and analyze the measured data, and use a fitting method to determine the link propagation loss difference PL_DL_DIFF between the current network and the planned network.

So far, the process of determining the link propagation loss difference between the current network and the planned network ends.

In actual use, the above-mentioned process of determining the link propagation loss difference PL_DL_DIFF between the current network and the planned network can be performed in this step 303, or can be predetermined before implementing this step, so as to improve calculation efficiency.

After determining the link propagation loss difference PL_DL_DIFF between the current network and the planned network, the received power corresponding to the MR reporting point in the planned network can be determined by the following formula:

Assuming that the received power RSRP corresponding to the MR reporting point when planning the network is P_Rx2, then:

P_Rx2＝P_Tx+Ga_BS-Lf_BS-PL_DL2+Ga_UE Formula (3)

Among them, PL_DL2 is the downlink propagation loss corresponding to the cell where the MR reporting point is located when planning the network. The calculation formula of PL_DL2 is as follows:

PL_DL2=PL_DL1+PL_DL_DIFF, that is, use the downlink propagation loss corresponding to the cell where the MR report point is located plus the link propagation loss difference between the current network and the planned network.

According to formula (3), it can be seen that when determining the received power P_Rx2 corresponding to the MR reporting point when planning the network, first determine the sum of the base station transmitting power P_Tx and the antenna gain (Ga_BS+ Ga_UE), and then use the obtained sum to subtract the downlink propagation loss PL_DL2 corresponding to the cell where the MR reporting point is located when planning the network and the feeder loss Lf_BS included in the base station information to obtain the corresponding MR reporting point when planning the network The received power P_Rx2.

In yet another preferred implementation manner provided in Embodiment 1, in order to further improve the accuracy of the determined simulation results, the target value required by the network planning for the received power may be preset, and the target value may be set according to the requirements of the network planning. Based on this setting, after determining the receiving power corresponding to each MR reporting point when planning the network in the above step 304, the determination result can be further compared with the set target value to determine the MR that can meet the network planning target value. Simulation results. Fig. 6 shows a schematic flow chart of determining a simulation result conforming to the target value, as shown in Fig. 6, mainly including the following steps:

Step 601: Determine the received power corresponding to each MR report point in the MR data from the acquired MR data, and determine the base station information corresponding to the cell where each MR report point is located from the acquired base station information.

Step 602: Determine the downlink propagation loss corresponding to the cell where each MR report point is located in the current network according to the received power corresponding to each MR report point and the base station information corresponding to the cell where each MR report point is located.

Step 603, according to the downlink propagation loss corresponding to the cell where each MR reporting point is located in the current network, and the determined link propagation loss difference between the current network and the planned network, determine that each MR reporting point is in the planned The downlink propagation loss corresponding to the cell where the network is located respectively.

Step 604, according to the downlink propagation loss corresponding to the cell where each MR reporting point is located when planning the network and the base station information corresponding to the cell where each MR reporting point is respectively located, determine that each MR reporting point is respectively located when planning the network. Corresponding received power.

The specific execution process of the above step 601 to step 604 is consistent with the specific execution process of the above step 301 to step 304, and will not be repeated here.

Step 605 , determine whether the received power corresponding to each MR reporting point meets the target value required by network planning for received power when planning the network, if yes, perform step 606 , if not, perform step 607 .

Step 605, the set target value may be the statistical value of the received power corresponding to each MR reporting point when planning the network, correspondingly, in this step, determine whether the corresponding receiving power of each MR reporting point when planning the network is To meet the target value required by network planning for received power, it is also necessary to first determine a statistical value based on the corresponding received power of each MR reporting point when planning the network, and then compare whether the statistical value meets the set target value. What is described here is only a preferred way to implement this embodiment. In practical applications, it is also possible to set a target value for the receiving power corresponding to each MR reporting point when planning the network, or set a target value for each MR reporting point When planning the network, the average value of the corresponding received power is used as the target value, and will not be listed here.

Step 606: Output the determined received power corresponding to each MR reporting point when planning the network as a network simulation result.

Step 607: After adjusting the first setting parameter in the base station information corresponding to the cell where each MR reporting point is located, return to step 601.

In this step 607, the parameter type and adjustment amount in the adjusted base station information can be set in advance, for example, one or more of the base station information such as the transmit power of the downlink common channel of the base station or the transmit frequency of the downlink common channel of the base station can be adjusted. In this case, the parameters adjusted in the base station information corresponding to the cells where the MR report points are respectively located are the same.

So far, the process of determining the simulation result conforming to the target value ends.

The above describes in detail the process of determining the simulation result when the simulation result in the first embodiment is the received power corresponding to each MR reporting point when planning the network. In the first embodiment, other network simulation results can also be further obtained, for example, one or more of the following parameters can be determined:

Determine the received power corresponding to each neighboring cell of the cell where each MR reporting point is located when planning the network;

Determine the SINR corresponding to the cell where each MR reporting point is located when planning the network;

Determine the capacity of the planned network.

Specifically, the determination process of each parameter is as follows:

1. Determine the received power corresponding to each neighboring cell of the cell where each MR reporting point is located when planning the network

The process of determining the received power corresponding to each adjacent cell of the cell where each MR report point is located when planning the network is the same. The following is for determining the received power corresponding to a neighboring cell of the cell where an MR report point is located when planning the network The process is described in detail.

Fig. 7 shows a schematic flow diagram of determining the received power corresponding to the neighboring cell of the cell where an MR report point is located when planning the network. As shown in Fig. 7, the determination process mainly includes the following steps:

Step 701. Determine the received power corresponding to the neighboring cell of the cell where the MR reporting point is located and the base station information corresponding to the neighboring cell.

Step 702: Determine the downlink propagation loss corresponding to the neighbor cell of the cell where the MR report point is located in the current network according to the received power corresponding to the neighbor cell of the cell where the MR report point is located and the base station information corresponding to the neighbor cell.

Step 703: According to the downlink propagation loss corresponding to the adjacent cell of the cell where the MR report point is located in the current network, and the determined link propagation loss difference between the current network and the planned network, determine that the MR report point is located at The downlink propagation loss corresponding to the adjacent cell of the cell where the network is planned.

Step 704: According to the downlink propagation loss corresponding to the adjacent cell of the cell where the MR report point is located when planning the network and the base station information corresponding to the adjacent cell of the cell where the MR report point is located, determine that the MR report point is in the planned network Receive power corresponding to the neighboring cell of the cell where the network is located.

So far, the process of determining the received power corresponding to the neighboring cell of the cell where an MR reporting point is located when planning the network is completed. In the above process, the specific implementation principles of steps 701 to 704 are basically the same as the specific implementation principles of the above steps 301 to 304, and will not be repeated here.

2. Determine the SINR corresponding to the cell where each MR reporting point is located when planning the network

After determining the received power corresponding to each MR report point when planning the network, and determining the received power corresponding to each adjacent cell of the cell where each MR report point is located when planning the network, you can further determine the The SINR corresponding to the cells where the reporting points are respectively located when planning the network. Specifically, the determination process of the SINR corresponding to the cell where each MR report point is located when planning the network is the same. The process of noise ratio SINR is described in detail.

Fig. 8 shows a schematic flow chart of determining the SINR corresponding to the cell where an MR reporting point is located when planning the network. As shown in Fig. 8, the determination process mainly includes the following steps:

Step 801: Determine the RSSI (Received Signal Strength Indication) corresponding to the MR reporting point according to the received power corresponding to each neighboring cell of the cell where the MR reporting point is located when planning the network.

Step 802: Determine the SINR corresponding to the cell where the MR reporting point is located when planning the network according to the received power corresponding to the MR reporting point when planning the network and the RSSI corresponding to the MR reporting point.

So far, the process of determining the SINR corresponding to the cell where an MR reporting point is located when planning the network ends.

In the above step 801, the RSSI corresponding to the MR reporting point includes adjacent cell interference and white noise, which can be determined by the following formula:

$\mathrm{RSSI}=\mathrm{\γ}*\underset{i=0}{\overset{N-1}{\mathrm{\Σ}}}({\mathrm{\α}}_i*{\mathrm{\β}}_i*{\mathrm{RSRP}}_i)+\mathrm{KTB}$ Formula (4)

in:

i represents the current MR reporting point;

α _i is the RSRP power and PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) power offset factor, generally 1;

β _i is the cell load factor;

γ is the interference elimination factor;

KTB is white noise.

In the above step 802, the SINR corresponding to the cell where the MR reporting point is located when planning the network can be determined by the following formula:

SINR＝RSRP/(RSSI-RSRP) Formula (5)

in:

RSRP refers to the received power corresponding to the MR reporting point when planning the network.

In yet another preferred implementation mode provided in Embodiment 1, in order to further improve the accuracy of the determined simulation results, the target value required by the network planning for the SINR can be set in advance, and the target value can be set according to the requirements of the network planning, based on For this setting, after the SINR corresponding to the cell where each MR reporting point is located when planning the network is determined through the process corresponding to Figure 8, the determination result can be further compared with the set target value to determine which can meet the requirements of the network. Simulation results for planning target values. Fig. 9 shows a schematic flow chart of determining a simulation result conforming to the target value, as shown in Fig. 9, mainly including the following steps:

Step 901: Determine the RSSI corresponding to the MR reporting point according to the received power corresponding to each neighboring cell of the cell where the MR reporting point is located when planning the network.

Step 902: Determine the SINR corresponding to the cell where the MR reporting point is located when planning the network according to the received power corresponding to the MR reporting point when planning the network and the RSSI corresponding to the MR reporting point.

The specific execution process of the above step 901 to step 902 is consistent with the specific execution process of the above step 801 to step 802, and will not be repeated here.

Step 903 : Determine whether the SINR corresponding to the cell where each MR reporting point is located when planning the network meets the target value required by the network planning for SINR, if so, perform step 904 , if not, perform step 905 .

In this step 903, the set target value can be the statistical value of the SINR corresponding to the cell where each MR reporting point is located when planning the network. The specific setting principle is the same as that set in step 605 above. The principle of value is basically the same, so I won't repeat them here.

Step 904: Output the determined SINR corresponding to the cell where each MR reporting point is located when planning the network as a network simulation result.

Step 905 , after adjusting the second setting parameter in the base station information corresponding to the cell where each MR reporting point is located, return to step 901 .

In this step 905, the parameter type and adjustment amount in the adjusted base station information can be preset, for example, one or more of the base station information such as the transmit power of the downlink common channel of the base station or the transmit frequency of the downlink common channel of the base station can be adjusted. In this case, the parameters adjusted in the base station information corresponding to the cells where the MR report points are respectively located are the same.

So far, the process of determining the SINR corresponding to the cell where an MR reporting point is located when planning the network ends.

3. Determine the capacity of the planned network

After determining the SINR corresponding to the cell where each MR reporting point is located when planning the network, the network capacity can be further determined. Figure 10 shows a schematic flow chart of determining the network capacity, as shown in Figure 10, which mainly includes the following steps:

Step 1001, according to the SINR corresponding to the cell where each MR report point is located when planning the network, and the corresponding relationship between the SINR and the data rate, determine the data rate corresponding to each SINR.

Step 1002, determine the product of the data rate corresponding to each SINR and the user distribution rate of the cell corresponding to the SINR.

In step 1002, the user distribution rate of the cell corresponding to the SINR is determined according to the MR data reporting frequency of the cell corresponding to the SINR, and the user distribution rate is proportional to the reporting frequency, that is, the greater the MR data reporting frequency of the cell, the greater the distribution of the cell. more users.

Step 1003: Add the product of the data rate corresponding to each SINR and the user distribution rate to obtain the capacity of the planned network.

So far, the process of determining the network capacity ends.

In the process corresponding to Figure 10, step 1002 and step 1003 can be determined by the following formula:

$\mathrm{no}=\underset{i=0}{\overset{N-1}{\mathrm{\Σ}}}{R}_i*x_i$ Formula (6)

in:

n represents the network capacity; i refers to the i-th MR reporting point, and N is the number of MR reporting points;

R _i represents the data rate corresponding to the SINR corresponding to the cell where the i-th MR reporting point is located when planning the network;

x _i represents the user distribution rate of the cell corresponding to the SINR of the cell where the i-th MR reporting point is located when planning the network.

In yet another preferred implementation mode provided in Embodiment 1, in order to further improve the accuracy of the determined simulation results, the target value of network planning for network capacity can be set in advance, and the target value can be set according to the requirements of network planning, based on For this setting, after the network capacity is determined through the flow corresponding to FIG. 10 , the determination result can be further compared with the set target value to determine a simulation result that can meet the network planning target value. Fig. 11 shows a schematic flow chart of determining a simulation result that meets the target value, as shown in Fig. 11, mainly including the following steps:

Step 1101 , according to the SINR corresponding to the cell where each MR reporting point is respectively located when planning the network, and the corresponding relationship between the SINR and the data rate, determine the data rate corresponding to each SINR.

Step 1102: Determine the product of the data rate corresponding to each SINR and the user distribution rate of the cell corresponding to the SINR.

Step 1103: Add the product of the data rate corresponding to each SINR and the user distribution rate to obtain the capacity of the planned network.

The specific execution process of the above step 1101 to step 1103 is consistent with the specific execution process of the above step 1001 to step 1003, and will not be repeated here.

Step 1104 , determine whether the capacity of the planned network meets the target value required by the network planning for capacity, if yes, perform step 1105 , if not, perform step 1106 .

In this step 1104, the set target value can be specifically set according to the number of users to be accommodated by the network.

Step 1105, output the determined network capacity as a network simulation result.

Step 1106: After adjusting the third setting parameter in the base station information corresponding to the cell where each MR reporting point is located, return to step 1101.

In this step 1106, the parameter type and adjustment amount in the adjusted base station information can be preset, for example, one or more of the base station information such as the transmit power of the downlink common channel of the base station or the transmit frequency of the downlink common channel of the base station can be adjusted. In this case, the parameters adjusted in the base station information corresponding to the cells where the MR report points are respectively located are the same.

So far, the process of determining the network capacity meeting the network planning requirements is completed.

In the first embodiment, if the determined network simulation result does not meet the target value required by the network planning, it is necessary to further adjust the base station information. Correspondingly, when the base station information is adjusted, the obtained base station information is the adjustment parameter The base station information corresponding to the cells where the MR report points are located.

The above describes the determination process when the network simulation results include different parameters. It should be understood that in the first embodiment, if the target value required by network planning is set for each network simulation result, each network simulation result can be determined. Finally, compare the network simulation result with its corresponding target value. If the corresponding target value is met, further determine the subsequent network simulation result. If not, you can first adjust the base station information, and then The network simulation result is re-determined until the determined network simulation result meets the corresponding target value, and then subsequent network simulation results are determined. For example, the determined network simulation results include the received power corresponding to each MR reporting point when planning the network (parameter 1), and the SINR corresponding to the cell where each MR reporting point is located when planning the network (parameter 2) And when planning the capacity of the network (parameter 3), since the determination of parameter 2 needs to be based on the determination result of parameter 1, and the determination of parameter 3 needs to be based on the determination results of parameter 1 and parameter 2, therefore, it is possible to determine each After the received power corresponding to each MR report point meets the target value of the received power required by network planning when planning the network, then determine the SINR corresponding to the cell where each MR report point is located when planning the network, and determine each MR After the SINRs of the cells where the reporting points are respectively located meet the target value required by the network planning for SINR, the network capacity is further determined until the network capacity meets the target value required by the planned network for network capacity. In this manner, when there are multiple network simulation results, the efficiency of determining the network simulation result of the target value meeting the network planning requirements can be improved.

Since the MR data is the measurement result of the actual network situation, it can reflect the actual network environment, so compared with the prior art , can improve the accuracy of network simulation results, so as to better guide network construction and optimization.

Furthermore, the network capacity of the present invention is determined based on the user distribution determined by the frequency of MR reports, while the prior art is randomly distributed according to the type of features, etc. Compared with the blindness of the determination method of the prior art, the user of the present invention Distribution predictions are more accurate.
