[0002] Traditional wireless network planning is mainly based on coverage. When capacity is limited or insufficient, capacity expansion planning is carried out. Moreover, the capacity expansion of traditional wireless networks is mainly based on downlink capacity requirements.

[0003] The target customers and industry applications of 5G industry applications are mainly limited by uplink capacity. This is due to the difference in the target customers and actual applications of traditional ToC networks and ToB networks. Therefore, the planning and evaluation methods of traditional ToC networks are obviously not suitable for the planning and evaluation of ToB industry private networks.

Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0041] Figure 5 It is a structural schematic diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Combine the following Figure 1 A method for evaluating configuration of a ToB industry private network of the present invention is described, comprising: step 101, calculating the total uplink bandwidth corresponding to each business area according to the maximum number of link terminals, the maximum concurrency rate and the uplink rate pre-configured for the ToB industry private network of each business area in the industry project;

[0044] Conduct business analysis on each business type under the ToB industry private network of a certain industry project, convert the business model into indicators that can be measured by the wireless network, such as wireless indicators such as downlink rate or uplink rate, latency and reliability, and classify them.

[0045] The purpose of business analysis is to convert business application requirements into requirements for wireless network indicators. Therefore, business model analysis is a prerequisite for toB industry application project planning. Accurate business model analysis is the most important aspect of SLA (Service Level Agreement) protection.

[0046] During the design, the needs of industry project services should be classified as much as possible, the application scenario areas should be divided, and the business area area should be calculated, as shown in Table 1. It should be emphasized that the accuracy of the business area area, that is, the effective coverage area of ​​the 5G private network, directly affects the accuracy of the subsequent network evaluation. For example, in an industrial park, the effective coverage area of ​​5G industry applications on its production line may only be the area of ​​a certain floor of the factory building, or even part of a certain floor of the factory building. If the effective coverage area at this time uses the floor area of ​​the entire park, it is obvious that the network scale evaluated later will be much larger than the actual required network scale, resulting in inaccurate evaluation and even waste of investment in private network construction.

[0047] Table 1 Statistical table of business analysis results of a certain industry project

[0048]

[0049] For example, for zone I, the service type is edge AI (Artificial Intelligence) detection, which is a large uplink service. The estimated overall capacity of zone I, that is, the total uplink bandwidth, is 40*80%*32=1024Mbps.

[0050] Step 102, according to the scene feature of each service area, obtaining the site type corresponding to the scene feature; wherein the scene feature is pre-associated with the site type;

[0051] The site type is a base station side product type. Optionally, the site type includes indoor PIXNET and macro AAU (Active Antenna Unit) equipment.

[0052] The scene features include characteristics of four scenes: standard factory, fully enclosed scene, semi-enclosed indoor scene and open scene.

[0053] Among them, standard factories such as parks are indoor scenes with limited installation space, high capacity density and strong interference. Reference is made to the use of indoor distributed Pifei sites, such as Lampsite and Qcell.

[0054] In fully enclosed scenarios, such as underground coal mines, where the space is long and narrow, it is difficult for the AAU beam to be deployed. Reference is made to the use of indoor distributed Picocell sites, such as Lampsite, Qcell, and BOOK RRU (Radio Remote Unit).

[0055] Semi-enclosed indoor large open factory building, height>30 meters, width>100 meters, AAU beam is easy to deploy. Reference to the use of macro base stations, such as AAU and RRU equipment.

[0056] In open scenarios, such as ports and rivers, the base station can be installed at a height of >25 meters, and the AAU beam is easy to deploy. Macro stations are preferred, such as AAU and RRU equipment.

[0057] Step 103, obtaining the wireless capacity type of each service area according to the total uplink bandwidth corresponding to each service area, the site type, the effective coverage area of ​​the pre-configured ToB industry private network and the pre-determined uplink edge rate of the ToB industry private network;

[0058] Optionally, the evaluation method in this embodiment takes uplink edge rate and capacity density as priority factors. Wherein, capacity density = uplink total bandwidth / effective coverage area. The selection of uplink edge rate is determined according to the uplink rate corresponding to each service area and the distribution of terminals in each service area.

[0059] Capacity is set based on the uplink edge rate and capacity density, that is, whether the environment is coverage-based or capacity-based, thereby obtaining the wireless capacity type. Most of the existing industry-specific network projects are capacity-based.

[0060] Step 104, obtaining the total number of each device deployed in each service area according to the number of each device deployed per unit area corresponding to the site type and wireless capacity type as a whole and the effective coverage area; wherein the site type and wireless capacity type as a whole are pre-associated with the number of each device deployed per unit area.

[0061] This embodiment estimates the equipment scale according to the site type and the wireless capacity type.

[0062] This embodiment starts with analyzing the customer's industry business, converts business requirements into network requirements, and then performs equipment selection and network equipment scale assessment. The equipment scale assessment uses site type and wireless capacity type as constraints to output the number of wireless devices that need to be configured in the industry-specific network, thereby achieving accurate and rapid assessment of the industry-specific network configuration.

[0063] On the basis of the above embodiment, the present embodiment describes calculating the total uplink bandwidth corresponding to each business area according to the maximum number of linked terminals, the maximum concurrency rate and the uplink rate pre-configured for the ToB industry private network of each business area in the industry project, including: converting the uplink rate corresponding to each business type in each business area according to the preset conversion ratio between each business type and the preset business type;

[0064] At present, ToB networking mainly focuses on large uplink services and low-latency and high-reliability services. For scenarios where low-latency and high-reliability services are mixed with large uplink services, RB (Resource Block) reserved slices or QoS (Quality of Service) priority can be used to ensure end-to-end low latency and high reliability.

[0065] For low-latency and high-reliability services, the equivalent capacity conversion ratio of toB low-latency and high-reliability services relative to eMBB services is derived from system simulation results, thereby achieving the unification of low-latency and high-reliability services and large uplink services, facilitating subsequent network capacity estimation and level planning.

[0066] For example, for zone II, PLC is a large uplink service, and remote control is a low-latency, high-reliability service, so it is necessary to convert remote control into a large uplink service for capacity conversion. Assuming the preset conversion ratio is 67%, the converted uplink rate is 1 / 67% = 1.5Mbps.

[0067] Calculate the uplink bandwidth corresponding to each service type in each service area according to the maximum number of linked terminals, the maximum concurrency rate and the converted uplink rate corresponding to each service type in each service area;

[0068] The estimated uplink bandwidth corresponding to the PLC in zone II is 40*30%*20=240Mbps. The estimated uplink bandwidth corresponding to the remote control service in zone II is 30*50%*1.5=22.5Mbps.

[0069] According to the uplink bandwidth corresponding to each service type in each service area, the total uplink bandwidth corresponding to each service area is obtained.

[0070] The estimated overall capacity of zone II, i.e., the total upstream bandwidth, is 240+22.5=262.5 Mbps.

[0071] On the basis of the above embodiments, before converting the uplink rate corresponding to each service type in each service area according to the preset conversion ratio between each service type and the preset service type, this embodiment also includes: according to the delay and transmission success rate pre-configured for the ToB industry private network of each service type, obtaining the preset conversion ratio corresponding to the delay and transmission success rate as a whole; wherein the delay and transmission success rate as a whole are pre-associated with the preset conversion ratio.

[0072] The air interface delay constraints include base station processing delay, UE processing delay, frame ratio, retransmission times and transmission delay, among which retransmission is the main factor affecting air interface delay. Taking the 8:2 time slot ratio of the 2.6G frequency band of the 5G network as an example, the initial transmission delay is distributed from 4 to 11ms, and one retransmission increases by about 5ms. The maximum number of retransmissions allowed under different delays is shown in Table 2.

[0073] Table 2 Maximum number of retransmissions allowed for different air interface delays under 8:2 time slot ratio

[0074] Air interface delay 10ms 20ms 30ms 40ms First transmission yes yes yes yes Retransmit 1 time no yes yes yes Retransmit 2 times no no yes yes Retransmit 3 times no no yes yes Retransmit 4 times no no no yes

[0075] The IBLER error rate of the base station is 10%, which means the transmission success rate is 90%. If the transmission success rate is increased to 99%, a relatively lower bit rate is used at the same target rate, that is, a lower-order modulation method is used to ensure reliability. At the same time, due to the reduction in bit rate, the system capacity will also be reduced.

[0076] Taking the 8:2 time slot ratio as an example, based on the three major factors of initial transmission, retransmission and delay constraint, the simulation deduces the conversion model of toB low-latency and high-reliability services relative to the traditional eMBB capacity as shown in Table 3. Other time slot ratios such as 7:3 are just differences in baseline capacity, and the conversion relationship can still refer to this table.

[0077] Table 3 Capacity conversion model of low-latency and high-reliability services relative to eMBB services

[0078]

[0079] From Table 1, it can be seen that the delay of the remote control service in zone II is 20ms, and the transmission success rate is 99.9%. From Table 3, it can be seen that the preset conversion ratio corresponding to the delay and the transmission success rate as a whole is 67%.

[0080] In order to meet the SLA requirements of industry applications for private network latency and reliability, this embodiment also takes low latency and high reliability requirements into consideration in the private network configuration evaluation, and converts the network requirements of low latency and high reliability services into equivalent values. Compared with the existing traditional ToC public network coverage-based wireless network planning, this embodiment is more suitable for the network configuration evaluation of private networks under 5G industry application scenarios.

[0081] Based on the above embodiments, Figure 2 As shown, in this embodiment, according to the total uplink bandwidth corresponding to each business area, the site type, the effective coverage area of ​​the pre-configured ToB industry private network and the pre-determined uplink edge rate of the ToB industry private network, the wireless capacity type of each business area is obtained, including: dividing the total uplink bandwidth corresponding to each business area by the effective coverage area to obtain the capacity density corresponding to each business area;

[0082] When the capacity density corresponding to each service area is less than or equal to the preset capacity density upper limit corresponding to each wireless capacity type under the site type, and the uplink edge rate is less than or equal to the preset uplink edge rate upper limit corresponding to each wireless capacity type under the site type, the wireless capacity type with the smallest preset capacity density upper limit and the smallest preset uplink edge rate upper limit among the wireless capacity types is used as the wireless capacity type of the ToB industry private network; wherein the wireless capacity type is pre-associated with the preset capacity density upper limit and the preset uplink edge rate upper limit.

[0083] In determining the capacity level, due to the different performance of indoor and macro base station equipment types, the capacity level and the number of equipment configurations corresponding to the level are also different. The following is an explanation of the indoor Pifei site and outdoor macro site respectively.

[0084] The capacity setting in the indoor distributed Pifei site evaluation model is a model obtained by empirical modeling based on the actual business needs and network construction delivery status of multiple industry projects that have completed wireless network construction and delivery, as shown in Table 4.

[0085] Wireless capacity types include thin network coverage, basic coverage, medium capacity, large capacity and ultra-large capacity. Each wireless capacity type has a corresponding preset capacity density upper limit and a preset uplink edge rate upper limit.

[0086] Table 4 Edge rate upper limit and capacity density upper limit corresponding to capacity gear

[0087]

[0088] The number of each device deployed per unit area for each wireless capacity type under the indoor PIF site is shown in Table 5. Since the number of devices configured for the capacity level is based on an effective coverage area of ​​10,000 square meters, when comprehensively evaluating the number of devices required for a project, it should be multiplied by the area coefficient μ, where the area coefficient μ = effective coverage area / 10,000 square meters, and the final number of devices should be rounded up to an integer.

[0089] Table 5 Capacity gear corresponding equipment configuration

[0090]

[0091] Without considering other means of capacity doubling, under the conditions of 2.6G 4TR 80MHz 8:2, D-MM networking, and antenna hanging height of 3 to 5 meters, the uplink pipe capacity = 288Mbps / cell. Assuming 8 pRRUs / cell, 1 rHub can support the connection of 4 pRRUs, 4 of the 8 ports of rHub are in use, and 4 are reserved. The baseband board is active and standby, that is, 1 BBU frame or 1 main control board can support 3 active and 3 standby 6 baseband boards, and 1 baseband board can only support 1 DMM cell. The data source refers to the actual park mobile phone factory project. This project is a typical large uplink demand project with high reference value.

[0092] According to the business requirements of a project in Table 1, Zone I is the factory production line area with an effective indoor coverage area of ​​20,000 square meters, and Zone II is the outdoor tally factory area with an effective coverage area of ​​40,000 square meters. The business edge rate of Zone I is 32Mbps, the total uplink bandwidth requirement is 1024Mbps, the capacity density = 512Mbps / 10,000 square meters, and it is set at the large capacity level. The area coefficient μ = 2, so it is evaluated that the list of indoor distributed PiFei sites that need to be configured in the business scenario of Zone I is 6 cells, 6 baseband boards, 2 BBUs and main control boards, 48 ​​pRRUs, the pRRU spacing is about 24 meters, and 12 rHubs.

[0093] The capacity setting in the outdoor macro base station evaluation model is also a model obtained through empirical modeling based on the actual business needs and network construction delivery status of multiple industry projects that have completed wireless network construction and delivery, as shown in Table 6.

[0094] Wireless capacity types include coverage, medium capacity, large capacity and ultra-large capacity. Each wireless capacity type has a corresponding preset capacity density upper limit and a preset uplink edge rate upper limit.

[0095] Table 6 Edge rate upper limit and capacity density upper limit corresponding to capacity gear

[0096]

[0097] The number of each device deployed per unit area for each wireless capacity type under the outdoor macro base station is shown in Table 7. Since the number of devices configured for the capacity level is based on 10,000 square meters, the actual number of devices should be multiplied by the area coefficient μ and rounded up.

[0098] Table 7 Capacity gear corresponding equipment configuration

[0099]

[0100] Without considering other means of capacity doubling, 2.6G 100MHz 8:2, conventional networking, antenna hanging height 25 meters, the macro station spacing should not be too dense, the spacing is more than 160 meters, 2.6G uplink pipeline capacity = 227Mbps / cell, 4.9G uplink pipeline capacity = 350Mbps / cell. Assuming that the conventional group has 1 RRU / cell or 1 AAU / cell, the baseband board is active and standby, that is, 1 site, 1 BBU frame or 1 main control board can support 3 active and 3 standby 6 baseband boards, and 1 baseband board supports 3 cells. The data source refers to a certain project, which is a typical large uplink demand project and has a high reference value.

[0101] According to the business requirements of a project in Table 1, Zone I is the production line area of ​​the factory, with an effective indoor coverage area of ​​20,000 square meters, and Zone II is the outdoor tally factory area, with an effective coverage area of ​​40,000 square meters. The business edge rate of Zone II is 20Mbps, the total uplink bandwidth requirement is 262.5Mbps, and the capacity density is 65.63Mbps / 10,000 square meters, which is set at the medium capacity level. The area coefficient μ=4, so it is evaluated that the list of macro station equipment that needs to be configured in the business scenario of Zone II is 1 site, 3 cells, 1 baseband board, 1 BBU and main control board, and 3 AAUs.

[0102] This embodiment relies on the actual wireless network configuration data of multiple planned or delivered industry projects, and forms a capacity equipment corresponding model with uplink capacity density and edge rate as constraints through modeling and deduction. It is more suitable for 5G industry private network application scenarios that are limited by uplink capacity, and can achieve rapid evaluation of 5G industry private network wireless network configuration.

[0103] On the basis of the above embodiments, the wireless capacity type of each service area is obtained according to the total uplink bandwidth corresponding to each service area, the site type, the effective coverage area of ​​the pre-configured ToB industry private network and the predetermined uplink edge rate of the ToB industry private network in this embodiment, and the maximum value of the uplink rates corresponding to all service types in each service area is used as the uplink edge rate corresponding to each service area.

[0104] Optionally, when selecting the uplink edge rate, if the terminal distribution map in each service area is unknown, the maximum value of the uplink rates corresponding to all service types in each service area is used as the uplink edge rate. As shown in Table 1, the uplink rate requirements corresponding to area II are 20Mbps and 1Mbps respectively, so the edge rate can be the maximum value of the two, that is, 20Mbps.

[0105] On the basis of the above embodiments, in this embodiment, after obtaining the site type corresponding to the uplink total bandwidth and the overall feature according to the uplink total bandwidth corresponding to each service area and the feature of each service area, the method further includes: when the isolation type of each service area is the first preset type and the site radio frequency band set for each service area is the same as the site radio frequency band of the public network, the time slot ratio set for each service area is less than or equal to the time slot ratio of the public network; wherein the time slot ratio is the time slot ratio of downlink to uplink;

[0106] The isolation type includes closed, semi-closed and open environments. This embodiment determines the site radio frequency band and time slot ratio of each service area according to the isolation type of the scene. Optionally, the first preset type includes a closed environment, and the second preset environment includes a semi-closed and open environment.

[0107] For example, in underground coal mines, the environment is closed and completely isolated from the public network environment. For example, in 2.6G, 100Mhz, the time slot ratio can be changed from the traditional 8:2 to 2:3 to improve the uplink capability. Or use the full frequency band for coverage.

[0108] When the isolation type of each service area is the second preset type, the site radio frequency band set for each service area is the same as the site radio frequency band of the public network, and the time slot ratio set for each service area is the same as the time slot ratio of the public network.

[0109] For example, for ports and factory buildings, since they are in contact with the public network macro base station due to their coverage, the subframe time slot ratio and frequency band usage should fully consider the uniform subframe time slot ratio of the entire network. That is, it should be consistent with the public network time slot ratio to avoid interference between time slots, time synchronization, and macro-private interference.

[0110] On the basis of the above embodiments, in this embodiment, after the total number of each device deployed per unit area and the effective coverage area corresponding to the site type and the wireless capacity type as a whole are obtained, the total number of each device deployed in each service area is obtained, and the device cost corresponding to each service area is obtained according to the total number of each device deployed in each service area and the unit price of each device corresponding to the site type; wherein the site type and the unit price of each device are pre-associated;
