[0031] The following will describe in detail a private network deployment evaluation method provided by this application in conjunction with the accompanying drawings.

[0032] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0033] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0034] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0035] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0037] The large-scale commercial use of 5G networks continues to empower all areas of production and life, and promotes the rapid development of the digital economy. As the construction of 5G fully connected factories will gradually move from the factory level to the workshop level and field level, and from "peripheral applications" to the "core of production", key link applications will expand from R&D, monitoring, warehousing, and operations to production operations. Applications also put forward higher requirements for the performance of 5G networks. Whether it can support the extensive connection of production units, whether it can provide more agile, flexible, and reliable networking solutions, and whether it has reliable network services have become issues that need to be solved for the further development of 5G. In order to solve the uncertainty problem of 5G networks in industry applications, all parties in the industry continue to collaborate and innovate, continuously improve the bandwidth, reliability, and positioning accuracy of 5G networks, reduce latency, jitter and other capabilities, and continue to promote the deep integration of 5G with the industry, especially the industrial Internet. The full integration into the core production links of digital factories puts forward further requirements for 5G, and it is expected that 5G will achieve three aspects of evolution and development. First, enhance the deterministic coverage and networking capabilities of 5G networks to achieve direct access to industrial networks; second, improve the deterministic communication capabilities of 5G networks to meet the stringent requirements of some industrial control scenarios for performance indicators; third, build a deterministic guarantee system for 5G networks to provide high reliability and high security for the 7×24 hours uninterrupted operation of digital factories. In many cases, ordinary 5G public networks cannot meet user needs, so it is necessary to accurately evaluate Internet network needs and deploy 5G private networks to meet users' specific network needs.

[0038] 5G private network is a wireless network customized for a specific organization or enterprise. It is based on 5G technology and provides higher data rates, lower latency and wider connectivity possibilities. However, when deploying 5G private networks in actual applications and industrial scenarios, the application scenarios of different vertical industries vary greatly, and service demand elements present diversified and customized requirements, including diversified requirements for vertical industry business scenarios, service indicators and business models, as well as customized requirements for speed, latency, reliability, isolation, security, etc. The above network capabilities, indicators and business models significantly affect the planning and construction goals of vertical industry networks. Network planning needs to solve the problems of flexible end-to-end resource layout and on-demand configuration of end-to-end network capabilities. Therefore, the deployment and construction of 5G private networks faces the challenges of on-demand planning and agile construction.

[0039] In addition, the private network deployment plan for the ToB industry is planned manually according to customer needs, and the industry private network configuration evaluation is basically conducted according to personal experience. Most of them are single business verifications, and there is a lack of private network deployment plans for all business types. In addition, the evaluation needs to comprehensively consider business needs, network technology, etc., and the required cycle is long. The evaluation conclusion is heavily dependent on the planning engineer's own experience. Therefore, different network planning engineers will have different or even greatly different evaluation results for the same industry project, and the evaluation accuracy is poor.

[0040] In response to the above technical problems, this application provides a private network deployment evaluation method, the idea of ​​which is that the network capabilities required for the private network coverage area can be determined based on different private network deployment demand information, the corresponding network SLA level can be determined based on the network capabilities required for the private network coverage area, and the private network deployment plan can be determined based on the private network deployment demand information and the network SLA level. The technical solution provided by this application provides a standardized framework for systematically evaluating and quantifying the Internet network capability requirements of different industries, and can realize the private network deployment evaluation that flexibly matches a variety of business scenarios, which not only saves human resource costs, but also enhances the accuracy of the evaluation and significantly improves the efficiency of the private network deployment evaluation.

[0041] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0042] The private network deployment evaluation method provided in this application can be applied to Figure 1 The private network deployment evaluation system shown in the figure. Figure 1 As shown, the private network deployment evaluation system includes: a back-end server 101 and a front-end device 102. The back-end server 101 and the front-end device 102 are connected to each other.

[0043] In some embodiments, the backend server 101 may be a server cluster consisting of multiple servers, or a single server, or a computer, or a processor or processing chip in a server or computer, etc. The embodiment of the present application does not limit the specific device form of the backend server 101. Figure 1 In the figure, the backend server 101 is taken as a single server as an example.

[0044] In some embodiments, the front-end device 102 may be a device for human-computer interaction with a user, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The specific device form of the front-end device 102 is not limited in the embodiments of the present application.

[0045] In some embodiments, the front-end device 102 sends the acquired private network deployment requirement information to the back-end server 101, and the back-end server 101 determines the corresponding network service level agreement SLA level according to the network capabilities required for the private network coverage area, and determines the private network deployment plan based on the private network deployment requirement information and the network SLA level.

[0046] See also Figure 2 , is a schematic diagram of the composition of the private network deployment evaluation system provided in the embodiment of the present application, such as Figure 2 As shown, the private network deployment evaluation system includes: input module, network capability demand evaluation module, network SLA level classification module, digital twin module, simulation module, device library module, terminal library module, network resource module, and deployment plan evaluation module. The above modules are interconnected.

[0047] The input module is used to obtain private network deployment requirement information.

[0048] Exemplarily, the private network deployment requirement information includes: business scenarios, business types, network capabilities required for business types, private network coverage areas, and connection density.

[0049] Among them, the above business scenarios are the scenarios included in each industry. For example, the scenarios that a smart mine-open-pit mine can include are: coal mining area, mining flat area, backfill area, crushing area, etc.

[0050] The above-mentioned business types are specifically the business types included in each business scenario. For example, the coal mining area mainly includes: unmanned driving of mining trucks, remote control of electric shovels, etc.

[0051] The network capabilities required for the above-mentioned service types are the network capabilities required for each service type, including: high uplink and downlink rates, low latency and high reliability, jitter, accurate positioning, high availability, and high security. The network capabilities required for different service types may be a single network capability or a mixture of multiple network capabilities.

[0052] The above-mentioned private network coverage area is the length, width and height of the area where the private network needs to be deployed.

[0053] The above connection density refers to the number of connections for each service type within the coverage area of ​​the private network, that is, the number of terminal devices that support simultaneous access to the private network to execute services of a certain service type.

[0054] The network capability requirement assessment module is used to assess the network capabilities required in the private network coverage area.

[0055] Exemplarily, the network capability demand assessment module can atomize the network capability of the 5G network so that it can be configured and adjusted dynamically on demand, so as to better realize the flexible combination and expansion of network functions to meet customized network services; then obtain the network capability required for each service type; finally, according to the connection density of each service type in the private network coverage area, obtain the network capability required in the private network coverage area. Exemplarily, the network capability required for the private network coverage area assessed by the network capability demand assessment module can be in the form shown in Table 1 below.

[0056] Table 1

[0057]

[0058] The network SLA level classification module is used to classify various indicators of the network SLA according to capability levels.

[0059] In some embodiments, the network SLA indicator includes at least one of the following: large uplink (i.e., efficient uplink data transmission), downlink rate, low latency and high reliability, jitter, positioning, high availability, high security, etc. The above network SLA indicators can be divided into different levels. Exemplarily, the network SLA indicators can be divided into 5 levels, and the higher the network SLA level, the higher the network capability required.

[0060] For example, the low latency and high reliability in the network SLA indicators can be divided into five levels: 100ms@99.9%, 50ms@99.99%, 20ms@99.99%, 10ms@99.99%, and 4ms@99.999%, which can be represented as SLA1-SLA5 respectively.

[0061] In some embodiments, after the network capabilities required for the private network coverage area are determined through the network capability demand assessment module, the network SLA level corresponding to each network capability can be determined respectively, and the user's demand for the network capability can be measured according to the network SLA level corresponding to the network capability.

[0062] It is understandable that by dividing the levels, the network capabilities can be uniformly quantified, and the network can be guaranteed according to different levels. By mapping the network capabilities of different industry scenarios to the network SLA level, the level of user demand can be quickly measured, thereby accelerating the industry's batch replication capabilities.

[0063] In some embodiments, the network capabilities required for different services may be a single network capability or a mixture of multiple network capabilities. If the service type requires multiple network capabilities, the corresponding network SLA level should also be the network SLA level corresponding to multiple network capabilities.

[0064] In some embodiments, the network SLA grading module is further used to determine the key technologies required to achieve each network SLA indicator.

[0065] Exemplarily, the key technology corresponding to each network SLA indicator may be one or a combination of multiple key technologies.

[0066] The key technologies corresponding to the large uplink indicators include at least one of the following: uplink multi-user multiple-input multiple-output (MU-MIMO), distributed massive multiple-input multiple-output (Massive MIMO), 1D3U frame structure time slot ratio, heterogeneous frequency multi-carrier, and uplink transmission selection.

[0067] The key technologies corresponding to the low-latency and high-reliability indicators include at least one of the following: normal scheduling request (SR) scheduling, uplink pre-scheduling, PRB resource reservation, packet data convergence protocol (PDCP) out-of-order delivery, low-rate modulation and coding scheme (MCS) / low-rate channel quality indicator (CQI), PDCP replication, Slot aggregation, non-time slot scheduling, uplink configuration authorization, flexible Ethernet (FlexE), dual transmit selection receive (DTSR), and complementary time division duplexing (TDD).

[0068] The key technologies corresponding to the jitter indicator include at least one of the following: wireless traffic shaping, time-sensitive networking (TSN), and time-sensitive control and auxiliary information (TSCAI).

[0069] The key technologies corresponding to the positioning indicators include at least one of the following: uplink time difference of arrival (UTDOA) triangulation positioning, angle of arrival (AOA) positioning, and fingerprint positioning.

[0070] The key technologies corresponding to the high availability indicators include at least one of the following: base station single board redundant backup, user plane function (UPF) 1+1 load sharing disaster recovery.

[0071] The digital twin module is used to perform three-dimensional (3D) modeling of the area where private network deployment planning will be carried out, map physical entities into digital twin models, virtualize equipment in industrial scenarios into models in digital twins, and virtualize existing network equipment into this module as the basis for subsequent simulations.

[0072] The simulation module is used to perform live network insight simulation and scenario modeling network simulation.

[0073] In some embodiments, the simulation module is used to perform existing network insight simulation, which means: before determining the private network deployment plan, simulation is performed based on the equipment configuration parameters of the existing network to determine the network coverage quality of the existing network in the private network coverage area; exemplarily, the network coverage quality may include at least one parameter: synchronization signal reference signal received power (synchronization signal reference signal received power, SS-RSRP), synchronization signal signal-to-interference plus noise ratio (synchronization signal signal-to-interference plus noise ratio, SS-SINR), uplink and downlink rates, and end-to-end delay.

[0074] If the private network is deployed at the workshop level or production line level, it is also necessary to evaluate the network situation at the park level. Also, evaluate the coverage capabilities of the existing network and the park, as well as the SS-RSRP, SS-SINR, uplink and downlink rates, and end-to-end delay of the signals invading the workshop level and production line level.

[0075] In other embodiments, the simulation module is also used for scenario modeling network simulation, which means: after the platform selects the optimal private network deployment plan, the scenario modeling network simulation is performed according to the optimal private network deployment plan to obtain the parameters such as SS-RSRP, SS-SINR, uplink and downlink rates, and end-to-end delay in the private network coverage area to determine whether it meets the business requirements of the scenario. This can avoid the situation where the network SLA does not meet the business requirements after the subsequent equipment is installed, and can save a lot of time and cost.

[0076] The device library module is used to store 5G network device information to facilitate the call of other modules.

[0077] Exemplarily, 5G network equipment includes: wireless equipment, core network equipment, bearer network equipment, and ToB customized equipment.

[0078] The wireless equipment includes but is not limited to at least one of the following: an indoor baseband unit (BBU), a large-scale active antenna system (AAU), a remote radio unit (RRU), and a digital differentiation room.

[0079] The core network equipment includes but is not limited to at least one of the following: an amplifier module (AMP) and a UPF.

[0080] The bearer network equipment includes but is not limited to at least one of the following: switches and industrial gateways; ToB customized equipment varies according to different industries and business needs, and may include edge computing units (mobile edge computing, MEC), coal mine explosion-proof, intrinsically safe base stations, chemical industry base stations, etc.

[0081] In some embodiments, the device library needs to contain detailed device information.

[0082] Exemplarily, the BBU equipment needs to include information such as manufacturer name, equipment model, hardware version number, software version number, typical power consumption (W), maximum power consumption (W), number of radio resource control (RRC) connected users per cell, number of activated users, number of supported cells, equipment price, etc.

[0083] The AAU / RRU equipment must include information such as manufacturer name, equipment model, hardware version number, software version number, supported frequency bands and bandwidths, size, weight, number of channels, typical coverage distance, maximum power consumption, typical power consumption, and equipment price.

[0084] The terminal library module is used to store information about 5G terminal devices, including 5G modules, customer premises equipment (CPE), reduced capability (RedCap) modules, ultra-reliable and low latency communications (URLLC) modules, and other terminals.

[0085] In some embodiments, the device library needs to contain detailed information, including: manufacturer name, device model, hardware version number, software version number, device price, etc. If the terminal library does not have the terminal information required by the customer, the customer needs to be asked and entered into the terminal library module.

[0086] The network resource module is used to store the network resource data provided by each network device to facilitate resource scheduling. It is necessary to count various data related to the number of PRB occupancy, including: single-user peak rate (uplink, downlink), single-cell capacity (uplink, downlink), single-cell URLLC connection number, etc.

[0087] Among them, the single-user peak rate (uplink and downlink) mainly considers different frequency bands, different bandwidths, different numbers of channels such as two transmitters-two receivers (2T2R) and four transmitters-four receivers (4T4R), theoretical peak rates under different frame structures, and the peak rates that can be achieved in actual environments.

[0088] The single-cell capacity (uplink and downlink) mainly considers different frequency bands, different bandwidths, different numbers of channels, different key technologies such as one downlink-three uplink (1d3u), MU-MIMO and MassiveMIMO under theoretical peak rates and actual capacities under different RSRP / SINR conditions.

[0089] The number of URLLC connections in a single cell mainly considers the number of connections in a single cell under different frequency bands, different bandwidths, different subcarrier spacings and different network SLA conditions, from which the number of PRBs occupied by each connection can be calculated.

[0090] The deployment plan evaluation module is used to call the data of the previous eight modules and output the optimal network deployment plan based on customer needs and data analysis results.

[0091] It should be noted that the system architecture described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can know that with the evolution of the system architecture, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

For example, the large uplink network capability within the region is the product of the large uplink network capability of each service type and the connection density; the downlink rate network capability within the region is the product of the downlink rate network capability of each service type and the connection density; the low latency and high reliability network capability within the region is the low latency and high reliability network capability of each service type, taking the highest one according to the requirements for network performance; the method for determining the network capabilities such as jitter, quasi-positioning, high availability, and high security required within the region is the same as the method for determining low latency and high reliability, and will not be elaborated here.

[0100] S203: Determine the network SLA level of the private network coverage area.

[0101] In some embodiments, before step S203, the method further includes: classifying the network SLA indicators into different levels.

[0102] Exemplarily, the network SLA indicators include at least one of the following: large uplink (i.e., efficient uplink data transmission), downlink rate, low latency and high reliability, jitter, positioning, high availability, high security, etc. The above network SLA indicators can be divided into different levels. Exemplarily, the network SLA indicators can be divided into 5 levels, and the higher the network SLA level, the higher the network capability required.

[0103] For example, taking the network SLA indicator of low latency and high reliability as an example, low latency and high reliability can be divided into five levels: 100ms@99.9%, 50ms@99.99%, 20ms@99.99%, 10ms@99.99%, and 4ms@99.999%, which can be represented as SLA1-SLA5 respectively.

[0104] In some embodiments, the network capability required for the private network coverage area may be a single network capability, and the network SLA level corresponding to the network capability required for the private network coverage area is the network SLA level corresponding to the network capability.

[0105] For example, when the network capability required for the private network coverage area is low latency and high reliability, if the latency required for the private network coverage area is 20ms, the network SLA level corresponding to the network capability required for the private network coverage area is SLA3.

[0106] In some embodiments, the network capability required for the private network coverage area may be a mixture of multiple network capabilities. In this case, the network SLA level corresponding to the network capability required for the private network coverage area is the highest network SLA level among the network SLA levels corresponding to the mixture of multiple network capabilities.

[0107] For example, if the network capabilities required in the private network coverage area include high uplink and downlink rates, low latency and high reliability, jitter, positioning, high availability, and high security, and if these seven network capabilities correspond to network SLA levels of SLA2, SLA1, SLA4, SLA3, SLA2, SLA3, and SLA3 respectively; then the network capabilities required in the private network coverage area correspond to the network SLA level of SLA4.

[0108] S204. Determine a private network deployment plan based at least on the private network deployment requirement information and the network SLA level.

[0109] In some embodiments, determining the private network deployment solution first requires determining the network construction method, and then determining the specific private network deployment solution according to the network construction method. For a specific description, please refer to the following steps S2041-S2042, which will not be repeated here.

[0110] Among them, Figure 4 As shown, the network construction method includes one of the following: virtual private network, hybrid private network, and physical private network.

[0111] The above-mentioned virtual private network refers to providing dedicated network services to enterprises through logical isolation on top of public network infrastructure. This network construction method does not involve the exclusive use of physical network facilities. Relying on the public network, soft slicing and 5G service quality indicators (5g qos indicator, 5QI) are used to jointly build virtual private networks to achieve differentiated services. Among them, soft slicing refers to the virtualization and flexible configuration of network functions through software-defined networking (SDN) and network functions virtualization (NFV) technologies. Virtual private networks are suitable for scenarios without data hard isolation requirements. In the core network nodes of virtual private networks, unified data management (UDM), session management function (SMF), AMF and UPF are all located in the public network.

[0112] The above hybrid private network refers to a part of the network facilities located at the local site of the enterprise, while the other part provides services through the public network infrastructure. Public network dedicated network services are provided through carrier isolation, wireless resource block (RB) resource reservation, UPF sinking, etc., and the 5GC user plane can be dedicated. In the core network nodes of the hybrid private network, UDM, SMF, and AMF are located in the public network.

[0113] The above-mentioned physical private network refers to a private network infrastructure that is completely independent of the public network, including base stations, core networks and other components that are deployed and managed by the enterprise itself. This approach provides the highest control and security, guarantees service quality and supports service isolation. The physical private network is suitable for workshops or production lines with relatively concentrated coverage, as well as scenarios with special requirements such as exclusive resources and data security. Relying on exclusive base stations, it can simultaneously achieve dedicated 5GC control planes and dedicated 5GC user planes. In the core network nodes of the physical private network, UDM, SMF, AMF and UPF are all located in the private network.

[0114] In some embodiments, S204 may be specifically implemented as S2041-S2042 as follows.

[0115] S2041. Determine a network construction method based at least on the network SLA level.

[0116] In some embodiments, determining the network construction mode based on the network SLA level can be implemented as follows: when the network SLA level is a first preset level, determining the network construction mode as a virtual private network; when the network SLA level is a second preset level, determining the network construction mode as a hybrid private network; when the network SLA level is a third preset level, determining the network construction mode as a physical private network, wherein the third preset level is greater than the second preset level, and the second preset level is greater than the first preset level.

[0117] Exemplarily, when the network SLA level in the private network deployment area is divided into five levels of SLA1-SLA5, the first preset level is SLA1; the second preset level is SLA2 or SLA3; and the third preset level is SLA4 or SLA5.

[0118] In some embodiments, the above method further includes: performing simulation based on device configuration parameters of the existing network to determine the network coverage quality of the existing network in the private network coverage area.

[0119] The equipment configuration parameters of the existing network include at least one of the following: transmission power, number of channels, frequency band, antenna downtilt angle, base station height, etc.

[0120] The network coverage quality may include at least one of the following: RSRP, SINR, uplink and downlink rates, and end-to-end delay.

[0121] In some embodiments, based on the above network coverage quality, the above step S2041 can also be implemented as: determining the network construction method based on the network SLA level and / or network coverage quality.

[0122] Exemplarily, determining the network construction mode based on the network SLA level and / or network coverage quality may be implemented as follows:

[0123] When the network coverage quality is greater than or equal to the first preset threshold and the network SLA level is the first preset level, determining that the network establishment mode is a virtual private network;

[0124] When the network coverage quality is greater than or equal to the first preset threshold and the network SLA level is the second preset level, the network construction mode is determined to be a hybrid private network;

[0125] When the network coverage quality is less than the first preset threshold and / or the network SLA level is the third preset level, the network construction method is determined to be a physical private network, wherein the third preset level is greater than the second preset level, and the second preset level is greater than the first preset level.

[0126] Exemplarily, in a factory operating environment, taking the network coverage quality including RSRP as an example, the first preset threshold may be -90 decibel-milliwatts (dbm).

[0127] It should be noted that the above-mentioned network construction method only takes into account the network SLA level and network coverage quality. In actual use, the customer budget and network construction cost must also be considered, and the network construction method is determined based on the customer budget and cost control.

[0128] S2042. Determine the private network deployment plan based on the network construction method and private network deployment requirement information.

[0129] Exemplarily, when the network construction method is a virtual private network, the private network deployment plan is determined based on the private network deployment demand information through soft slicing and 5G service quality indicator (5g qos indicator, 5QI) technology.

[0130] Exemplarily, when the network construction method is a hybrid private network, based on the private network deployment requirement information, the private network deployment plan is determined through carrier isolation, wireless resource block (RB) resource reservation, UPF sinking, etc.

[0131] For example, when the network is built as a physical private network, independent devices are used for the control plane and the user plane to provide a highly secure and highly isolated network. If high availability is required, an independent core network 1+1 backup is required.

[0132] It should be noted that the first "1" in the UPF 1+1 backup in the hybrid private network construction plan refers to the active UPF instance, which is responsible for processing all normal data traffic; the second "1" refers to the backup UPF instance, which is usually idle or only monitors and does not participate in actual data processing. When the active UPF fails, the backup UPF can quickly take over its work to ensure uninterrupted service. In the independent core network 1+1 backup in the physical private network construction plan, the first "1" refers to the active component, which is the main component responsible for processing all business traffic under normal circumstances. In the 5G architecture, the active component is generally a specific core network node, such as the access and mobility management function (AMF) or UPF; the second "1" refers to the backup component, which is usually in standby mode, but is always ready to take over its responsibilities when the active component fails or requires maintenance.

[0133] In some embodiments, Figure 5 As shown, in the case where the network construction mode is a physical private network, the above step S2042 can be implemented as the following steps S301-S304:

[0134] S301. Determine the frequency of private network deployment based on the network construction method and business scenarios.

[0135] In some embodiments, when the network construction method is a physical private network, the frequency impact between the existing network and the physical private network is determined according to the business scenario, and the private network deployment frequency is determined based on the frequency impact.

[0136] Exemplarily, considering the mutual impact between the existing network and the private network, a heterogeneous frequency deployment method is adopted.

[0137] For example, if the business scenario is an indoor scenario, if the outdoor macro station deployment frequency of the existing network is 3500-3600 MHz, then the indoor private network deployment frequency can be any one of the following: 3300-3500 MHz, 2.1 GHz, millimeter wave frequency band, etc.

[0138] S302. Determine the network resources required for private network deployment based on the network capabilities required for the private network coverage area.

[0139] It can be understood that the network resources required for the above-mentioned private network deployment are device resources that can provide the network capabilities required for the private network coverage area.

[0140] For example, when the network capability required in the private network coverage area is low latency and high reliability, if the latency required in the private network coverage area is 20ms, the network resources required for the above-mentioned private network deployment are device resources that can provide a network capability with a latency no higher than 20ms.

[0141] S303: Select a suitable wireless network device from the device library based on the network resources required for private network deployment, the network resources provided by a single device in the device library, and private network deployment requirement information.

[0142] The network resources required for private network deployment, the network resources provided by a single device in the device library, and the private network deployment requirement information can be formed into a table, as shown in Table 2. Under single network capabilities and multiple network capabilities, the device station types that meet the requirements can be screened out according to the table. The table is as follows:

[0143] Table 2

[0144]

[0145] Considering the type of network capabilities required for the private network coverage area, the above step S303 has the following implementation methods:

[0146] Implementation method 1: The network capability required for the private network coverage area is a single network capability.

[0147] In some embodiments, when the network capability required for the private network coverage area is a single network capability, the above step S303 can be implemented as follows:

[0148] Sa1. When the network resources provided by a single device can meet the network resources required for the above-mentioned private network deployment, the above-mentioned private network deployment device is selected from the above-mentioned device library based on the above-mentioned private network deployment requirement information.

[0149] Sa2. When the network resources provided by the above-mentioned single device cannot meet the network resources required for the above-mentioned private network deployment, determine whether the network resources provided by the combined frequency band can meet the network resources required for the above-mentioned private network deployment.

[0150] Sa3. When the network resources provided by the above-mentioned combined frequency band can meet the network resources required for the above-mentioned private network deployment, the above-mentioned private network deployment equipment is selected from the above-mentioned equipment library based on the above-mentioned private network deployment demand information and the above-mentioned combined frequency band.

[0151] In some embodiments, based on the private network deployment requirement information and the combined frequency band, selecting the private network deployment device from the device library may be implemented as follows:

[0152] Based on the above-mentioned private network deployment requirement information and the above-mentioned combined frequency bands, combined with the wireless device library, if the multi-mode device contains the above-screened frequency band combination, consider factors such as cost and power consumption, select an optimal wireless device station type in the multi-mode device; if the multi-mode device does not contain the above-screened frequency band combination, select a suitable wireless device station type from other devices.

[0153] Sa4. When the network resources provided by the above-mentioned combined frequency band cannot meet the network resources required for the above-mentioned private network deployment, determine whether the frequency band of the same frequency as the outdoor base station can meet the network resources required for the above-mentioned private network deployment.

[0154] Sa5. When the network resources provided by the frequency band of the outdoor base station can meet the network resources required for the private network deployment, use the frequency band of the outdoor base station for deployment. At this time, consider the interference situation and select a suitable wireless equipment station type in combination with the equipment library.

[0155] Sa6. When the frequency band of the above-mentioned outdoor base station cannot meet the network resources required for the above-mentioned private network deployment, determine whether the network resources provided after the frequency band of the heterogeneous deployment is split into cells can meet the network resources required for the above-mentioned private network deployment.

[0156] Sa7. When the network resources provided after the cell splitting of the frequency bands deployed with different frequencies can meet the network resources required for the above-mentioned private network deployment, the cell splitting of the frequency bands deployed with different frequencies shall be carried out to suppress interference as much as possible, and a suitable wireless equipment station type shall be selected in combination with the equipment library.

[0157] Sa8. If all of the above means cannot meet the network resources required for the above-mentioned private network deployment, it means that the 5G private network deployment cannot meet the network capabilities required for the private network coverage area.

[0158] Implementation method 2: The network capabilities required for the private network coverage area are multiple network capabilities.

[0159] In some embodiments, when the network capabilities required for the private network coverage area are multiple network capabilities, the network resources required for private network deployment also include the number of PRB occupancy required for private network deployment, and the network resources provided by a single device also include the maximum number of PRBs for a single device. The above step S303 can be implemented as follows: based on the number of PRB occupancy required for private network deployment, the maximum number of PRBs for a single device in the device library and the private network deployment requirement information, select a private network deployment device from the device library.

[0160] In some embodiments, based on the number of PRBs occupied by the private network deployment, the maximum number of PRBs of a single device in the device library, and the private network deployment requirement information, selecting a private network deployment device from the device library can be implemented as follows:

[0161] Sc1. When the required network capability is multiple network capabilities, the number of PRBs occupied by different network capabilities in different frequency bands, different bandwidths, different numbers of channels, and different subcarriers.

[0162] In some embodiments, the number of PRB occupancy for different network capabilities may be determined using the formula:

[0163]

[0164] It should be noted that the above formula only represents the method of calculating the PRB occupancy number when the hybrid service contains three network capabilities: large uplink and downlink rates and low latency and high reliability. If the network capabilities required by the hybrid service are different from this, the formula can be increased or decreased as needed.

[0165] For example, if the hybrid service only includes two network capabilities: large uplink and low latency and high reliability, the formula can be expressed as:

[0166]

[0167] If the hybrid service includes network capabilities such as high uplink and downlink rates, low latency and high reliability, jitter, and positioning, the formula can be expressed as:

[0168]

[0169] Sc2. When the network resources provided by a single device can meet the network resources required for the above-mentioned private network deployment, that is, the number of PRBs calculated according to the above formula is less than the PRB number of the cell.max , then based on the above private network deployment requirement information, select the above private network deployment device from the above device library.

[0170] Sc3. When the network resources provided by the above single device cannot meet the network resources required for the above private network deployment, that is, the number of PRBs of a single cell of all station types is greater than the number of PRBs of the cell. max , determine whether the network resources provided by the combined frequency band can meet the network resources required for the above-mentioned private network deployment.

[0171] Sc4. When the network resources provided by the above-mentioned combined frequency band can meet the network resources required for the above-mentioned private network deployment, that is, the number of PRBs in the private network coverage area is less than the number of PRBs in cell 1. max1 +PRB of cell 2 max2 +…, further screen out the combined frequency bands that meet the requirements, and select the above-mentioned private network deployment device from the above-mentioned device library based on the above-mentioned private network deployment requirement information and the above-mentioned combined frequency bands.

[0172] In some embodiments, based on the private network deployment requirement information and the combined frequency band, selecting the private network deployment device from the device library may be implemented as follows:

[0173] Based on the above-mentioned private network deployment requirement information and the above-mentioned combined frequency bands, combined with the wireless device library, if the multi-mode device contains the above-screened frequency band combination, consider factors such as cost and power consumption, select an optimal wireless device station type in the multi-mode device; if the multi-mode device does not contain the above-screened frequency band combination, select a suitable wireless device station type from other devices.

[0174] Sc5. When the network resources provided by the above-mentioned combined frequency band cannot meet the network resources required for the above-mentioned private network deployment, that is, the number of PRBs in the private network coverage area is greater than the PRBs of cell 1 max1 +PRB of cell 2 max2 +…, determine whether the frequency band of the outdoor base station can meet the network resources required for the above-mentioned private network deployment.

[0175] Sc6. When the network resources provided by the frequency band of the outdoor base station can meet the network resources required for the private network deployment, the frequency band of the outdoor base station is used for deployment. At this time, the interference situation must be considered. The number of PRB occupancy under different interference situations must be considered, and a suitable wireless equipment station type must be selected in combination with the equipment library.

[0176] Sc7. When the frequency band of the outdoor base station cannot meet the network resources required for the private network deployment, determine whether the network resources provided after the cell splitting of the frequency band of the heterogeneous deployment can meet the network resources required for the private network deployment.

[0177] Sc8. When the network resources provided after the cell splitting of the frequency bands with different frequency deployments can meet the network resources required for the above-mentioned private network deployment, the cell splitting of the frequency bands with different frequency deployments shall be carried out to suppress interference as much as possible. It is necessary to consider the number of PRB occupancy under different interference conditions and select a suitable wireless equipment station type in combination with the equipment library.

[0178] Sc9. If all of the above means cannot meet the network resources required for the above-mentioned private network deployment, it means that the 5G private network deployment cannot meet the network capabilities required for the private network coverage area.

[0179] In some embodiments, when making preliminary equipment selection, factors such as coverage scenarios, protection requirements, and industry constraints must also be considered. These include:

[0180] When the coverage scenario is outdoor, if the equipment installation conditions are good, the base station can be deployed at a height of more than 25 meters, which is conducive to beam deployment. Multi-antenna Massive MIMO products can be used, such as 64 / 32 transmit / receive channel base station antenna units (transmit / receive active antenna unit, TR AAU) devices. For scenarios with limited installation scenarios, small and medium-sized equipment can be used, such as 8T8R pole stations.

[0181] When the coverage scenario is a factory building with ordinary floor height and no special protection requirements, indoor distribution equipment can be used, such as 4T4R digital indoor distribution equipment. For other factories with higher floor heights or special protection requirements, outdoor small and medium-sized high-protection-level AAU / RRU equipment can be used, such as 8T8R pole station equipment.

[0182] When the coverage scenario is an ordinary indoor office area or a scenario with high bandwidth demand, 4T4R digital indoor distribution equipment can be used. When the bandwidth demand is not large, 2T2R indoor distribution equipment can be used.

[0183] In some industries, special protection requirements for equipment need to be considered, such as explosion-proof requirements in the coal mining industry and anti-corrosion requirements in the chemical industry.

[0184] S304. Determine the technical solutions for the core network and the bearer network.

[0185] In the deployment of the core network, both the control plane and the user plane use independent equipment to provide a highly secure and highly isolated network; if there is a requirement for high availability, an independent core network 1+1 backup is required.

[0186] The bearer network construction plan is determined based on the network requirements and network SLA levels corresponding to different services. If a service requires multiple network capabilities, it is necessary to consider the bearer network construction plan by integrating multiple network capabilities. If there are multiple available plans, it is also necessary to comprehensively consider factors such as customer budget and power consumption to select the most appropriate plan.

[0187] For example, for private network deployment needs with low latency network requirements above SLA3, the bearer network must adopt the sinking campus + network slicing solution. If there is a requirement for high availability, the bearer adopts the access ring network + aggregation core port solution.

[0188] In some embodiments, the above method further includes: after completing the selection of wireless equipment and determining the technical solutions for the core network and the bearer network, the installation location of the equipment is loaded into the digital twin module, and after setting the corresponding parameters, the scenario modeling network simulation is performed to simulate whether the SS-RSRP, SS-SINR, uplink and downlink rates and end-to-end delay of the coverage area meet the network capabilities required by the scenario. If satisfied, the network deployment plan ends. If not satisfied, the next level of solutions are selected in turn for simulation again until the business needs are met.

[0189] The private network deployment evaluation method provided in the present application can determine the network capabilities required for the private network coverage area based on different private network deployment demand information, determine the corresponding network service level agreement SLA level according to the network capabilities required for the private network coverage area, and determine the private network deployment plan based on the private network deployment demand information and the network SLA level. This private network deployment evaluation provides a standardized framework for systematically evaluating and quantifying the Internet network capability requirements of different industries, and can realize private network deployment evaluation that flexibly matches a variety of business scenarios, which not only saves human resource costs, but also enhances the accuracy of the evaluation and significantly improves the efficiency of private network deployment evaluation.
