Description

Global coding communication method and system

Technical Field

The invention belongs to the field of wireless communication, and relates to a high-speed adjustable high-efficiency wireless communication method, a plurality of network high-speed communication methods and protocols, a communication method and a communication system for unified coding and unified control among the plurality of network communication methods and modulation modes.

Background

SDN (software-defined networking)/NFV (network function virtualization), which is one of the key means in the 5G era expected to solve the problems faced by the current cellular network. As a novel network architecture and construction technology, the idea of control and data separation, software and virtualization advocated by the method brings hopes for breaking through the dilemma of the existing network. In the 5G vision promulgated by the european union, it is explicitly proposed that future 5G network developments will be supported using SDN/NFV as the underlying technology. The core features of the SDN architecture are openness, flexibility, and programmability. The system mainly comprises 3 layers, wherein an infrastructure layer is positioned at the bottommost layer of the network and comprises a large number of basic network devices, the infrastructure layer processes and forwards data according to rules issued by a control layer, a middle layer is the control layer and mainly takes charge of arranging resources of a data forwarding surface, controlling network topology, collecting global state information and the like, and the topmost layer is an application layer and comprises a large number of application services, and the network resources are called through an open northbound API.

Software Defined Wireless Networking (SDWN) wireless networks currently face a series of challenges. First, a large number of heterogeneous networks exist in a wireless network, such as LTE, Wimax, UMTS, WLAN, etc., and the phenomenon of coexistence of heterogeneous wireless networks will last for a considerable period of time. At present, the main challenges of heterogeneous wireless networks are difficult to communicate with each other, difficult to optimize resources, and wasted wireless resources, which is mainly because the existing mobile networks adopt a design mode of a vertical architecture. In addition, one-to-many models (i.e. a single network characteristic is used for multiple services) in the network cannot provide customized network guarantee for the characteristics of different services, and the network service quality and the user experience are reduced. Therefore, the SDN thought is introduced into the wireless network, so that the phenomenon of closure rigidity of the existing wireless network is broken, and the dilemma of the wireless network is thoroughly changed. The software defined wireless network reserves the core idea of the SDN, namely, a control plane is decoupled from distributed network equipment, the network centralized control on logic is realized, and the data forwarding rule is uniformly issued by the centralized controller. The architecture of the software defined wireless network is divided into 3 layers. In the software defined wireless network, the control plane can acquire, update and predict the whole network information, such as user attributes, dynamic network requirements and real-time network states. Therefore, the control plane can well optimize and adjust resource allocation, forwarding strategies, flow table management and the like, network management is simplified, and the pace of business innovation is accelerated. But little research has been done on increasing the transmission rate of the network, even though it is generally believed that they do not allow the network to become faster.

As a novel network architecture and construction technology, a great deal of research, experiments and verification are carried out on the intelligentization aspect of self-organizing networks (SON), the ideas of control and data separation, software and virtualization advocated by the SDN/NFV bring hopes for breaking through the predicament of the existing network, particularly the openness, flexibility and programmability of the SDN architecture, and the control plane of the network equipment is separated from the equipment and is put on a controller with a network control function for centralized control.

Software Defined Radio (SDR) is a wireless communication technology that uses modern Software to manipulate and control traditional "pure hardware circuits", and is to construct an open, standardized, modular, general hardware platform, where various functions, such as operating frequency band, modem type, data format, encryption mode, communication protocol, etc., are performed by Software, and to make broadband a/D and D/a converters as close to antennas as possible, so as to develop a new generation wireless communication system with high flexibility and openness. The selection of various communication frequency bands such as HF, VHF, UHF, SHF and the like is realized through software programming, and the sampling, quantization, coding/decoding, operation processing and transformation of transmitted information are completed through the software programming so as to realize the transceiving function of a radio station; the selection of different channel modulation modes, such as amplitude modulation, frequency modulation, single side band, data, frequency hopping, spread spectrum and the like, is realized through software programming, and different security structures, network protocols, control terminal functions and the like are realized through software programming. A software defined radio is a system and architecture that must have the ability to be reprogrammable and reconfigurable to enable devices to be used with multiple standards, multiple frequency bands and to perform multiple functions, that will not only use programmable devices to implement baseband digital signal processing, but will also program and reconfigure the analog circuitry for radio and intermediate frequencies, and that one of the requirements for the functionality of a software defined radio includes the ability to be reprogrammed and reconfigured, the ability to provide and change services, the ability to support multiple standards, and the ability to intelligently utilize spectrum, etc. It should be appreciated that SDR is not a stand alone technology, but a common platform that can be used for all technologies. The most important point of difference between the software defined radio and the software radio is that the former does not require all aerial wireless signals in the whole frequency band (2 MHz-2000 MHz) to be received, but finds out the frequency band and system most suitable for communication in the air at present by means of manual configuration/automatic search.

The noun explains:

WI-FI: is a technology that allows an electronic device to connect to a Wireless Local Area Network (WLAN), typically using the 2.4G UHF or 5G SHF ISM radio frequency bands. Connecting to a wireless local area network is typically password protected; but may be open, allowing any device within range of the WLAN to connect.

FM technology: frequency Modulation is a very common broadcasting technology, and can broadcast sound signals with high fidelity, and portable navigators basically have an FM transmitting function at present.

Bluetooth (Bluetooth:): the wireless technology standard can realize short-distance data exchange (using UHF radio waves of ISM wave band of 2.4-2.485 GHz) between fixed equipment, mobile equipment and a building personal area network. Bluetooth was originally created by telecommunications grand ericsson in 1994, as an alternative to RS232 data lines. The Bluetooth can be connected with a plurality of devices, and the problem of data synchronization is overcome

The fourth generation mobile phone mobile communication standard of 4G wireless network refers to the fourth generation mobile communication technology, foreign language abbreviation: and 4G. The technology comprises two modes of TD-LTE and FDD-LTE (strictly speaking, LTE is only 3.9G, although the LTE is advertised as a 4G wireless standard, the LTE is not accepted as a next generation wireless communication standard IMT-Advanced described by the international telecommunication union by 3GPP, so the LTE does not reach the 4G standard in a strict sense.

The 5G wireless network, the fifth Generation mobile communication technology (english: 5th Generation mobile networks or 5th Generation wireless systems, 5th-Generation, 5G for short) is the latest Generation cellular mobile communication technology, and is an extension behind the 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (gsm) systems. The performance goals of 5G are high data rates, reduced latency, energy savings, reduced cost, increased system capacity, and large-scale device connectivity. The first phase of the 5G specification in Release-15 was to accommodate early commercial deployments. The second phase of Release-16 will be completed in month 4 of 2020 and is submitted to the International Telecommunications Union (ITU) [1] as a candidate for IMT-2020 technology. The ITU IMT-2020 specification requires speeds up to 20 Gbit/s, and can implement wide channel bandwidth and large capacity MIMO. In order to increase the flow rate by thousands of times of 5G and achieve a transmission rate of more than 20Gbps, various available communication technologies such as a multi-carrier aggregation technology for increasing the frequency spectrum bandwidth, a large-scale antenna, an ultra-dense networking, a novel multi-address technology, a full-spectrum access and a novel network architecture are adopted at present.
