Description

Technical Field

[0001] This invention relates to the field of industrial internet technology, specifically to a method and system for constructing a converged network based on regional multi-enterprise networks. Background Technology

[0002] Currently, 5G technology is primarily applied in the coal mining sector within the energy industry. Looking at existing 5G projects in the domestic market, most are in the form of private networks, with MEC (Multi-access Edge Computing) deployed to the customer side. This allows private network data to be separated through the core network element UPF (User-Defined Network Function) on the customer side, maintaining a high-efficiency data transmission channel and ensuring data stays within the designated area. However, with the continuous development of technology and business demands, some potential drawbacks of 5G private network applications include: limited and unreasonable allocation of spectrum resources. 5G private networks require dedicated or shared spectrum to achieve high-speed, low-latency, and high-connectivity communication. However, spectrum resources are limited, and spectrum planning and management vary across different operators and regions. This may lead to challenges and risks in the deployment and operation of 5G private networks due to limited spectrum resources and the inability of private networks to meet the needs of public networks shared by operators.

[0003] The cost and complexity of network construction and operation. 5G private networks require the deployment of more base stations, core networks, edge computing and other equipment and platforms to meet the customized needs of vertical industries. This increases the investment and difficulty of network construction, and also brings higher operation and maintenance costs and complexity. Currently, when the traditional energy industry uses 5G private network technology, the user unit needs to build core network, transmission network and base station equipment to meet the access needs of the private network. If it is a large energy industry, with various units or departments distributed in different cities, each unit or department needs to build its own core network, transmission network and base station equipment, resulting in duplication of construction among units of the same energy company and facing huge duplication of investment problems.

[0004] Large energy companies typically use leased data lines from operators to form networks. This solution has been in use for many years, but it has several drawbacks in practice: high cost, low flexibility, and the inability to adjust bandwidth and activate services immediately. These drawbacks significantly limit the scope for business development. Summary of the Invention

[0005] In view of the above-mentioned problems, the present invention is proposed.

[0006] Therefore, the technical problem solved by this invention is that branch enterprises in different regions or cities need to repeatedly invest in the construction of 5G core networks in order to use 5G private networks.

[0007] To address the aforementioned technical problems, this invention provides the following technical solution: a method for constructing a converged network based on regional multi-enterprise networks, comprising: constructing a 5G private network core network; constructing a backbone transmission network across multiple enterprises using an optical transport network; providing personalized network services to different enterprise departments through network slicing; transmitting optical fiber to user desktops using passive optical network technology; and linking the optical transport network to the 5G private network core network to achieve multi-enterprise core network sharing and ensure network security.

[0008] As a preferred embodiment of the regional multi-enterprise converged network construction method described in this invention, the core network is constructed through Access and Mobility Management Function (AMF), User Plane Function (UPF), and Session Management Function (SMF). During construction, communication interfaces need to be reserved. When AMF and UPF communicate, they communicate through the N11 interface; when AMF and SMF communicate, they communicate through the N2 interface; and when SMF and UPF communicate, they communicate through the N4 interface.

[0009] As a preferred embodiment of the regional multi-enterprise converged network construction method described in this invention, the optical transport network includes: OTU3 and a synchronous mapping mode; the OTU3 is a level 3 optical channel frame structure with a transmission rate of 43.0 Gbps; the optical transport network also includes three cross-link functions: ODUk cross-link, OCh cross-link, and OPS cross-link. When the signal is transmitted in the electrical layer, ODUk cross-link is used to integrate and multiplex signals of different rates; when the signal is transmitted in the optical layer, OCh cross-link is used to realize long-distance optical transmission of the signal; when the signal is transmitted in the packet layer, OPS cross-link is used to dynamically exchange and schedule different signals.

[0010] As a preferred embodiment of the regional multi-enterprise converged network construction method described in this invention, the optical transport network further includes dynamic resource scheduling using a recurrent neural network.

[0011]

[0012] o t =f(W o ·h t +b o )

[0013] Among them, h t W represents the hidden state at time t; f represents the activation function; W x The weight matrix representing the input to the hidden state; x t This represents the optical transport network bandwidth usage at time t, where T represents the total number of sample times; W h h represents the weight matrix hidden to the hidden state. t-1Represents the hidden state at time t-1; σ represents the Sigmoid activation function; \odot represents element-wise multiplication; r t-1 This represents the flow rate of different signals; m represents the total number of signals; W o This represents the weight matrix hidden into the output state; o t-1 This represents the output of t-1; b h This represents the bias of the hidden state.

[0014] As a preferred embodiment of the regional multi-enterprise-based converged network construction method described in this invention, the recurrent neural network includes an activation function f that is a tanh activation function.

[0015]

[0016] The Sigmoid activation function is:

[0017]

[0018] Where σ(x) represents the value after being mapped by the Sigmoid function, and x is the input;

[0019] The network performance is tested using the mean squared error loss function.

[0020]

[0021] Among them, y i Indicates the actual allocated bandwidth; This represents the bandwidth that needs to be allocated; N represents the total number of samples.

[0022] As a preferred embodiment of the regional multi-enterprise converged network construction method described in this invention, the network slicing is implemented using FlexE slicing technology. The specific steps are as follows: determining the bandwidth and quality of service requirements of different enterprise departments; dividing the high-speed Ethernet interface into multiple low-speed sub-interfaces, each sub-interface corresponding to a customer channel; developing a FlexE calendar, where each time slot corresponds to a customer channel allocation table, and the allocation ratio of different customer channels in the time slot can be flexibly adjusted; allocating traffic from different services to the corresponding customer channels to ensure that each service obtains the required bandwidth; and adjusting the occupancy ratio of customer channels in the time slots according to the actual needs of the services to adapt to changes in services.

[0023] As a preferred embodiment of the regional multi-enterprise converged network construction method described in this invention, the network security includes: defining different roles, each with different operating permissions in the system; when a new user joins the system, a role is assigned to the new user according to their job responsibilities; when a user logs into the system and attempts to access resources, the system checks the user's role; if the role has the corresponding permissions, the system will allow access and modification; if the role does not have the corresponding permissions, the system will refuse access.

[0024] Secondly, this invention also provides a converged network construction system based on regional multi-enterprise networks, including: a data acquisition module for collecting network requirements, 5G network architecture, and communication interface protocol data of different enterprises; a network construction module for constructing a 5G private network core network and backbone transmission network based on the collected data and linking them with the networks of each enterprise; and a network application module for providing personalized network services to different enterprise departments through network slicing and using passive optical network technology to transmit optical fiber to the user's desktop, thereby realizing multi-enterprise core network sharing.

[0025] Thirdly, the present invention also provides a computing device, including: a memory and a processor;

[0026] The memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions, which, when executed by the processor, implement the steps of the regional multi-enterprise converged network construction method.

[0027] Fourthly, the present invention also provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, implement the steps of the method for constructing a converged network based on regional multi-enterprise entities.

[0028] The beneficial effects of this invention are: This invention enables branches or enterprises in different regions or cities to use 5G private networks without having to repeatedly invest in building 5G core networks. By creating a good converged network, it can fully realize the long-distance and high-efficiency network communication needs within the enterprise and achieve a high degree of network unification throughout the company.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this invention.

[0038] Example 1

[0039] Reference Figure 1 As an embodiment of the present invention, a method for constructing a converged network based on regional multi-enterprise is provided, comprising:

[0040] S1: Build a 5G private network core network and use optical transmission networks to build backbone transmission networks in multiple enterprises.

[0041] Furthermore, AMF and UPF are two important network elements in the 5G private network core network, responsible for control plane and user plane functions respectively. AMF is the access and mobility management function, supporting UEs with different mobility management needs. UE refers to user equipment, i.e., terminal devices in the 5G network, such as CPEs, mobile phones, tablets, and laptops. Different UEs may have different mobility management needs; for example, some UEs are stationary, some are mobile, and some need to switch between different access networks. AMF provides corresponding services to the UE based on its mobility management needs, performing tasks such as registration, connection, reachability, mobility management, access authentication, and access authorization. UPF is the user plane function, performing tasks such as packet routing and forwarding, policy enforcement, traffic reporting, and QoS (Quality of Service) processing.

[0042] When constructing a 5G private network core, communication interfaces need to be reserved. Communication between the AMF and UPF occurs through the N11 interface; between the AMF and SMF through the N2 interface; and between the SMF and UPF through the N4 interface. The N11 interface is primarily responsible for transmitting signaling related to session management, mobility management, and policy control. The N2 interface is mainly used for transmitting NAS signaling, RRC signaling, and PDU session-related signaling. The N4 interface is primarily used for transmitting signaling related to session management, policy control, and user plane configuration.

[0043] Furthermore, by leasing existing resources from telecommunications operators (ISPs), OTN networks can be built between enterprises in different cities as backbone transmission networks to achieve cross-regional long-distance high-speed data transmission and establish one or more high-speed private network channels.

[0044] OTN technology mainly includes the following aspects:

[0045] OTN Frame Structure: OTN defines a unified optical channel frame structure, namely OTU, for carrying client signals of different rates and formats. There are four OTU levels, and the OTU frame consists of three parts: transmission overload, forward error correction, and payload. This method uses OTU3 level construction, with a transmission rate of 43.0 Gbps. OTU3 is suitable for scenarios requiring high bandwidth and large-capacity data transmission and has a certain degree of compatibility, supporting different types of communication protocols and data formats. If future communication demands continue to increase, the network's transmission capacity can be expanded by using higher-level OTU units (such as OTU4) to accommodate the ever-increasing data traffic.

[0046] OTN Mapping Mechanism: OTN defines a universal mapping mechanism, the General Mapping Process (GMP), to map client signals of different rates and formats into OTU frames. GMP supports three modes: asynchronous mapping, transparent mapping, and bit-synchronous mapping, which can adapt to various client signals. This method uses the synchronous mapping mode, mainly because it can improve transmission efficiency and reduce latency and overhead. Therefore, its application in this method is most suitable for the development needs of large-scale regional energy companies.

[0047] OTN Cross-Connect Capabilities: OTN supports cross-connect capabilities at different layers, namely ODUk cross-connect, OCh cross-connect, and OPS cross-connect. ODUk cross-connect is implemented at the electrical layer, enabling grooming and multiplexing of ODUk signals; OCh cross-connect is implemented at the optical layer, enabling wavelength routing of OCh signals; OPS cross-connect is implemented at the packet layer, enabling packet switching of OPS signals. This achieves dynamic scheduling capabilities at the OTN level, meeting the underlying transmission requirements for dynamic scheduling of network resources in large regional energy enterprises as described in this method.

[0048] OTN Protection Mechanisms: OTN supports protection mechanisms at different layers, namely OCh protection, ODUk protection, and OPS protection. OCh protection is implemented at the optical layer and mainly includes three modes: 1+1 protection, 1:1 protection, and shared protection ring network. ODUk protection is implemented at the electrical layer and mainly includes three modes: linear protection, ring network protection, and subnet connection protection. OPS protection is implemented at the packet layer and mainly includes two modes: path protection and ring network protection. The appropriate protection mechanism should be selected based on the specific usage environment.

[0049] Furthermore, dynamic resource scheduling is achieved through recurrent neural networks. The weight matrix is ​​randomly initialized, and then updated according to the rate of change of the loss function with respect to the weights, thereby gradually reducing the loss function.

[0050]

[0051] o t =f(W o ·h t +b o )

[0052] Among them, h t W represents the hidden state at time t; f represents the activation function; W x The weight matrix representing the input to the hidden state; x t This represents the optical transport network bandwidth usage at time t, where T represents the total number of sample times; W h h represents the weight matrix hidden to the hidden state. t-1 Represents the hidden state at time t-1; σ represents the Sigmoid activation function; \odot represents element-wise multiplication; r t-1 This represents the flow rate of different signals; m represents the total number of signals; W o This represents the weight matrix hidden into the output state; o t-1 This represents the output of t-1; b h This represents the bias of the hidden state.

[0053] Over the long term, the bandwidth requirements of each company headquarters or department tend to stabilize; therefore, the activation function f is the tanh activation function.

[0054]

[0055] The Sigmoid activation function is:

[0056]

[0057] Where σ(x) represents the value after being mapped by the Sigmoid function, and x is the input;

[0058] The optimization objective of the mean squared error loss function is to minimize the gap between the actual allocation and the expected allocation, thereby making the resource allocation closer to the desired state. Therefore, the mean squared error loss function can be used to evaluate network performance.

[0059]

[0060] Among them, y i Indicates the actual allocated bandwidth; This represents the bandwidth that needs to be allocated; N represents the total number of samples.

[0061] S2: Provides personalized network services to different enterprise departments through network slicing, and uses passive optical network technology to transmit fiber optic cables to the user's desktop.

[0062] Furthermore, sliced ​​packet network (SPN), intelligent transport network (STN), or IP radio access network (IPRUN) equipment are deployed within each enterprise's headquarters and branch offices, connected to the OTN network, to build an efficient and flexible network within the enterprise. SPN, STN, and IPRAN are all technical solutions for mobile bearer networks, used to realize data transmission between base stations and the core network.

[0063] SPN and STN primarily differ in their slicing technologies. SPN uses FlexE technology for hard slicing, deploying soft-slice L2VPN / L3VPN within the hard slices and carrying them on the SR. STN, on the other hand, uses SRv6+EVPN technology for soft slicing, deploying hard-slice FlexE within the soft slices. SPN's slicing technology is more efficient, while STN's is more flexible. Therefore, both network standards have their advantages, and the choice depends on which is more suitable for the local enterprise deployment.

[0064] By utilizing FlexE-based slicing technology, the enterprise's internal network is divided into multiple independent slices, providing personalized, efficient, and secure network services for different business operations or departments. Specific steps include:

[0065] Determine the bandwidth and quality of service requirements for different enterprise departments; divide the high-speed Ethernet interface into multiple low-speed sub-interfaces, each sub-interface corresponding to a client channel. A FlexE client channel refers to the logical channel corresponding to each sub-interface within a FlexE group, and it has a unique identifier (e.g., 0-255); develop a FlexE calendar, in which each time slot corresponds to a client channel allocation table, and the allocation ratio of different client channels in the time slot can be flexibly adjusted; allocate the traffic of different services to the corresponding client channels to ensure that each service obtains the required bandwidth; adjust the occupancy ratio of client channels in the time slots at any time according to the actual needs of the services to adapt to changes in services.

[0066] FlexE-based slicing technology allows each service to obtain a customized network slice, enabling efficient utilization and flexible configuration of network resources. This method is most suitable for application in this context, and its technical approach is more suitable for the development needs of enterprises than other slicing technologies.

[0067] Furthermore, PON central office equipment (OLT) is deployed within each branch office and connected to network equipment such as OTN, SPN, STN, or IPRUN that do not belong to the grassroots branch office. The prepared slices are then allocated to different logical service networks, bringing the network to the office desktop and enabling high-speed broadband access.

[0068] The PON technologies used in this invention include XG-PON and XGS-PON. XG-PON is suitable for enterprises that do not have particularly high requirements for uplink speed but still need a large downlink bandwidth. XG-PON provides a downlink speed of 10Gbps and a relatively low uplink speed, which is suitable for scenarios within enterprises that need to download large amounts of data but have relatively low uplink requirements. For example, an enterprise may need to frequently download large files or data from the Internet, but the uplink speed requirement is relatively low.

[0069] XGS-PON is more advantageous for enterprises requiring greater bandwidth and symmetrical upload and download speeds. Because XGS-PON offers symmetrical 10Gbps upload and download speeds, it is suitable for applications that require high-speed data upload and download, such as enterprises that frequently transfer large files, conduct real-time video conferencing, or use cloud services.

[0070] When businesses need to download large amounts of data but have relatively few upload requirements, they can use XG-PON to transmit fiber optic cables to the user's desktop. When businesses need to frequently transfer large files or conduct real-time video conferences, they can use XG-PON to transmit fiber optic cables to the user's desktop.

[0071] S3: Link the optical transport network to the 5G private network core network to enable multi-enterprise core network sharing and ensure network security.

[0072] Furthermore, by connecting the OTN network to the 5G private network core network and leasing resources from telecom operators, enterprises in different cities can be connected to the shared 5G private network core network, achieving the goal of a "single network" across the entire network. Within the 5G private network core network, enterprises are authenticated and authorized based on their authentication information and access permissions, ensuring that only legitimate enterprises can access and use the 5G private network services.

[0073] Network security measures, including authentication and access control, data encryption, and security monitoring, ensure the confidentiality and integrity of network data. A centralized network management and monitoring platform is utilized to monitor and manage the entire network in real time, guaranteeing network stability and performance.

[0074] The authentication and access control is role-based access control, which defines different roles, each with different operating permissions in the system. When a new user joins the system, a role is assigned to the new user according to their responsibilities. When a user logs into the system and attempts to access resources, the system checks the user's role. If the role has the corresponding permissions, the system will allow access and modification; if the role does not have the corresponding permissions, the system will deny access.

[0075] Data encryption uses the Advanced Encryption Standard (AES) with a 128-bit key length. A 128-bit key is generated through a secure key exchange protocol. The sender uses the shared key and encryption algorithm to encrypt the file, and the receiver must use the shared key and decryption algorithm to decrypt the ciphertext and restore it to plaintext, ensuring that file information is not easily stolen even in insecure network environments.

[0076] This embodiment also provides a regional converged network construction system, including: a data acquisition module, which collects network requirements, 5G network architecture and communication interface protocol data of different enterprises; a network construction module, which builds a 5G private network core network and backbone transmission network based on the collected data and links them with the networks of each enterprise; and a network application module, which provides personalized network services to different enterprise departments through network slicing, and uses passive optical network technology to transmit optical fiber to the user desktop to achieve multi-enterprise core network sharing.

[0077] This embodiment also provides a computing device, including a memory and a processor; the memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions to implement the method for building a converged network based on regional multi-enterprise as proposed in the above embodiment.

[0078] This embodiment also provides a storage medium storing a computer program that, when executed by a processor, implements the regional multi-enterprise converged network construction method proposed in the above embodiments.

[0079] The storage medium proposed in this embodiment belongs to the same inventive concept as the regional multi-enterprise converged network construction method proposed in the above embodiments. Technical details not described in detail in this embodiment can be found in the above embodiments, and this embodiment has the same beneficial effects as the above embodiments.

[0080] Based on the above description of the implementation methods, those skilled in the art can clearly understand that the present invention can be implemented using software and necessary general-purpose hardware, and of course, it can also be implemented using hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product can be stored in a computer-readable storage medium, such as a computer floppy disk, read-only memory (ROM), random access memory (RAM), flash memory, hard disk, or optical disk, etc., including several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute the methods of the various embodiments of the present invention.

[0081] Example 2

[0082] Reference Figure 2 As an embodiment of the present invention, a method for constructing a converged network based on regional multi-enterprise is provided.

[0083] like Figure 2 As shown, the company headquarters establishes dedicated networks with different functions, connecting to branch offices in multiple locations through a leased OTN network architecture from an operator. Branch offices provide network functions to multiple sites via SPN and other network architectures, enabling data transmission between base stations and the core network. Simultaneously, they provide branch offices with intranet, extranet, operation and maintenance management, and video conferencing functions. This achieves the goal of a unified network across the entire organization, meeting the high-speed, efficient, and secure communication needs of a large energy enterprise, and demonstrating strong innovation in network architecture. The solution fully utilizes existing technologies and leased resources, reducing implementation risks and costs, and improving the reliability and usability of the entire network.

[0084] This method utilizes the OTN network as the backbone network to address the high-speed data transmission needs of large energy enterprises across regions and over long distances, enabling rapid data exchange and sharing between different cities. Through the sharing of the 5G private network core network, enterprise branches in different cities can share a single 5G private network core network, improving network resource utilization and avoiding redundant construction and waste.

[0085] At the same time, it saves on network construction costs. By leasing resources from telecommunications operators, it avoids the high costs of large energy companies building their own networks, reducing investment in network construction and the technical barriers associated with self-operation and maintenance.

[0086] By utilizing network slicing capabilities in technologies such as SPN, STN, and IPRUN, personalized configuration and management of the enterprise's internal network can be achieved, providing independent and flexible network services for different business units or departments. Through a PON access network, high-speed broadband access can be provided to the enterprise's internal offices, improving employee work efficiency and data transmission speed.

[0087] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
