Detailed Description
The following description of the embodiments of the present invention will be made in detail, but clearly, the embodiments are illustrative only and not all embodiments; all other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The intelligent 5G network communication system provided in this embodiment includes:
user terminal equipment: the user terminal equipment is an entrance of a 5G network communication system and comprises a smart phone, a tablet personal computer, a notebook computer, an Internet of things device and the like. These devices access the 5G network via wireless connections (e.g., cellular networks) for communication and data transfer with other devices. User terminal devices are typically equipped with high performance processors, large memory space, and high resolution screens to support faster data transfer rates and better user experience. Specifically, the user terminal device refers to various devices used by a user in a 5G network communication system to enable connection and communication with a network. The user terminal device may be a smart phone, a tablet computer, a notebook computer, an internet of things device, a smart watch, etc. These devices are typically equipped with wireless communication capabilities (e.g., cellular network, wi-Fi, bluetooth, etc.) for data transmission and communication with other devices via wireless connections with the 5G network.
And (3) a base station: a base station is an infrastructure in a 5G network, consisting of a series of antennas, radio frequency devices and processors. The base station is responsible for converting the wireless signals into digital signals, and performing signal processing and scheduling to enable data to be transmitted in the network. The 5G base station has a higher transmission rate and lower delay than the conventional network. In addition, the 5G base station also supports Multiple Input Multiple Output (MIMO) technology, and uses multiple antennas for signal transmission and reception, so as to improve network capacity and coverage. The arrangement mode of the base station comprises the following steps: 1. macro base station: macro base stations are the most common base station types in 5G networks, are usually installed in high-rise buildings, mountain tops and other high places, and have large coverage areas. The macro base station has higher transmission power, can provide longer-distance coverage, and is suitable for wide-area coverage of cities and suburbs. 2. Micro base station: micro base stations have smaller coverage than macro base stations and are usually installed on street lamp poles, indoors and the like. Micro base station coverage is typically between a few hundred meters and a kilometer, is suitable for densely populated urban areas and indoor environments, and can provide higher network capacity and data transmission rate. 3. Cell: a cell is a form of base station with smaller coverage and is typically installed in a high-density population area such as a building interior, mall, airport, subway station, etc. Cells may provide high capacity and high rate network connections to meet the communication needs of densely populated areas. 4. Indoor base station: indoor base stations are installed inside buildings and are mainly used to provide coverage and capacity enhancement of indoor areas. The indoor base station can make up the difference of indoor and outdoor signals, provides better signal quality and user experience, and is suitable for indoor places such as large markets, office buildings, hospitals and the like. 5. Edge base station: an edge base station is a base station deployed at the edge of a network, intended to provide low-latency and high-bandwidth services. The edge base station is usually installed at a position close to a user, such as a street lamp post, roadside facilities and the like, so that a faster data response time can be provided for the user, and the edge base station is suitable for application scenes with high delay requirements.
Core network: the core network is the backbone of the 5G network and is responsible for handling the transmission and routing of user data. It consists of control plane and user plane. The control plane is responsible for handling signaling and control messages such as registration, authentication and mobility management of the user. The user plane is responsible for handling data transfer, transferring user data from a source to a destination. The core network has high flexibility and programmability, and can be configured and optimized in real time according to the requirements so as to provide better network services. In particular, it consists of a control plane and a user plane, each with different functions and components. 1. Control surface: the control plane is responsible for handling signaling and control messages and controlling the behavior of the various elements in the network. The following are the main components of the control surface: user registration and authentication: the control plane handles the registration and authentication procedures of the user equipment. When the user equipment accesses the network, the control plane is responsible for verifying the identity and authority of the user equipment. Mobility management: the control plane is responsible for handling the mobility of the user equipment in the network, i.e. when the user equipment is handed over from one base station to another, the control plane coordinates this procedure, ensuring that the user's connection is not interrupted. Session management: the control plane is responsible for managing user sessions, including establishing, modifying, and terminating user sessions. It maintains the state of communication between the user equipment and the network. 2. User plane: the user plane is responsible for handling data transfer, transferring user data from a source to a destination. The following are the main components of the user plane: data transmission and routing: the user plane is responsible for transmitting user data from the source device to the destination device and for routing during the transmission process to ensure a fast and reliable transmission of the data. Data encryption and decryption: the user plane is responsible for encrypting and decrypting the user data, and protecting the security and privacy of the user data. Transmission protocol: the user plane uses different transport protocols, such as IP and TCP, to achieve reliable transport of data and flow control.
Software Defined Networking (SDN): a software defined network is a network architecture and management method that enables flexibility, programmability, and manageability of a network by separating the control plane from the data forwarding plane of the network. In conventional networks, network devices (e.g., routers, switches) typically have an integrated control plane and data forwarding plane, with the control plane being responsible for deciding and configuring the paths and policies of the network, and the data forwarding plane being responsible for actual packet forwarding. Such centralized network management approaches often face limitations and complexities that make it difficult to quickly adapt to different application requirements and network changes. The key idea of SDN is to concentrate control logic of a network in one or more centralized controllers, and implement centralized control and management of the network by communicating with network devices. And the controller issues a control instruction to the network equipment through an interface (such as an OpenFlow protocol) opened by the network according to the application requirements and the network state, and controls the forwarding path and the strategy of the data packet. The main characteristics and advantages of SDN include: network flexibility and programmability: SDN can carry out flexible network configuration and arrangement through a programming interface of a controller according to the requirements of application. The network administrator can define the behavior and the strategy of the network according to specific requirements, and realize the dynamic adjustment and optimization of the network. Centralized control and management: controllers in the SDN centrally manage and control the entire network, unify decision making and configuration of paths and policies of the network. The centralized control mode enables network management to be simplified and manageable, and network changes and faults can be responded quickly. Network slicing and multi-tenant support: SDN can divide the network into a plurality of independent segments on logic, and each network slice can provide independent network service and resources for different applications or tenants, so that isolation and sharing of the resources are realized. Automation and programming capabilities: the programming interface and open controller of the SDN enable automation of network management and services. By writing scripts or applications, automated network management, failure recovery, and service deployment can be achieved. Advanced network functions and services: SDN may support more flexible and innovative network functions and services such as network security, load balancing, traffic optimization, etc. By implementing these functions in the controller, deployment and upgrade of network functions can be simplified and higher quality of service and performance can be provided.
Virtualized Network Function (NFV): virtualized network functions are a network architecture and technology that converts traditional network functions (e.g., routers, firewalls, load balancers, etc.) into virtualized software instances to run on a generic server. Conventional network functions are typically implemented in the form of dedicated hardware devices, each of which requires separate hardware devices to support. Such hardware implementation has some problems, such as high hardware cost, complex deployment and maintenance, low resource utilization, etc. The goal of NFV is to transform these network functions from dedicated hardware to software modules that can run on a general-purpose server through virtualization technology to increase the flexibility, scalability, and resource utilization of the network. In NFV architecture, network functions are referred to as virtual network functions, which run in the form of software on a general-purpose server in a virtualized environment. Each VNF may be deployed and managed as a separate instance, with resource isolation and management provided by a virtualization platform (e.g., a virtual machine manager or container platform). The following are the main features and advantages of NFV: resource sharing and flexibility: through virtualization technology, multiple VNFs may run on the same physical server, sharing computing, storage, and network resources of the server. This sharing of resources makes deployment and extension of network functions more flexible and efficient. Elastic expansion and contraction: NFV allows VNF instances to be dynamically deployed, started, and stopped at runtime as needed. This ability to elastically stretch enables the network function to automatically adjust to changes in traffic load. Quick deployment and upgrade of network functions: the network function is realized in a software mode, and quick deployment and upgrading can be realized. The network administrator may deploy and manage the VNF in the virtualized environment in a remote manner without having to replace hardware devices in the field. Orchestration and automation of network functions: NFV may be combined with a software defined network, orchestrating and managing VNFs by a controller. This ability to orchestrate and automate allows for more flexibility and intelligence in the combination and scheduling of network functions. The cost is saved: NFV can reduce hardware cost, energy consumption, and maintenance cost of network functions by using general servers and virtualization technology. Simultaneously, NFV can also improve resource utilization, reduces the wasting of resources.
Edge calculation: edge computing is a distributed computing architecture that brings computing, storage, and application services close to data sources and end devices to reduce latency and bandwidth consumption of data transfer and provide faster, safer, and more reliable services. Traditional cloud computing models concentrate computing and storage resources in a cloud data center, and users transmit data to the cloud data center through a network for processing and storage. However, when the centralized computing mode faces big data, the internet of things, real-time application and other scenes, the problems of high delay, network congestion and privacy safety are faced. The goal of edge computation is to move computation and storage capacity to edge nodes closer to the data sources and end devices, such as base stations, routers, edge servers, etc. These edge nodes may be located at the edge of the network, near the user's location, or near where the data source is located. The edge nodes may perform a portion of the computational tasks, process and analyze data, and provide real-time responses and services. The main features and advantages of edge computation include: low delay: edge computation moves computation and data storage closer to the user, reducing the distance and time of data transmission, and thus reducing latency. This is of great importance for real-time applications (e.g. intelligent transportation, industrial control), internet of things devices and interactive applications. Bandwidth optimization: by performing data processing and analysis at the edge nodes, the amount of data transmitted to the cloud data center may be reduced, thereby reducing the need for network bandwidth. This is particularly important in cases of network congestion and limited bandwidth. Data privacy and security: the edge calculation processes and analyzes the data on the edge nodes, so that the risk of transmitting the sensitive data to the cloud data center is reduced, and the privacy and safety of the data are improved. Offline operation and network disconnection fault tolerance: the edge node can operate in an offline state and has the capability of network disconnection and fault tolerance. When the network connection is unstable or broken, the edge node may continue to perform computing tasks and transmit the results to the cloud data center when the network is restored. Distributed computing and co-processing: edge computing may distribute computing tasks over multiple edge nodes, enabling distributed computing and collaborative processing. Such a distributed architecture may increase computing power and processing efficiency, and support massive parallel processing.
Optical fiber transmission: backbone networks for 5G networks typically employ optical fiber transmission to meet the increasing data transmission demands. The optical fiber transmission has the advantages of high bandwidth, low loss, strong anti-interference capability and the like, and can realize high-capacity data transmission and high-speed communication. Through optical fiber transmission, the 5G network can support more users to simultaneously perform high-speed data transmission.
Multiple Input Multiple Output (MIMO) technology: the mimo technology is a key technology in a 5G network, and improves the capacity and coverage of wireless signals by using multiple antennas for signal transmission and reception. Both the base station and the user terminal equipment in the 5G network can adopt the MIMO technology, and the throughput and the coverage area of the network are improved by simultaneously using a plurality of antennas to transmit and receive data. The MIMO technology can fully utilize space resources and improve the reliability and the transmission rate of signals.
High frequency band: higher frequency resources, such as millimeter wave bands, are used in 5G networks. In contrast, conventional cellular networks mainly use low frequency bands. The high-frequency band has larger bandwidth and transmission rate, and can support more wireless devices to simultaneously perform high-speed data transmission. However, the transmission distance of the high-frequency signal is shorter, and the penetration capability of the high-frequency signal to the obstacle is also weaker, so that denser base station deployment is required in the 5G network to ensure the coverage and performance of the network. The high frequency band mainly includes the following ranges: 1. millimeter wave frequency band: the millimeter wave band is generally referred to as the frequency range of 30GHz to 300 GHz. This band is characterized by a very large bandwidth that can provide transmission rates of several kilomega bits per second (Gbps). However, millimeter wave signal transmissions are shorter in distance, less penetrating through obstacles, and require denser base station deployment to provide continuous coverage. 2. Medium-high frequency: the medium-high frequency range includes frequencies Below 6GHz, and is generally divided into a low frequency band (Below 1 GHz), a medium frequency band (1 GHz to 6 GHz), and a medium-high frequency band (2 GHz to 4 GHz). The advantage of this band is that the signal transmission distance is relatively long, the penetration capacity is strong, and the band is suitable for wide area coverage, but the transmission rate is relatively low.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
