Detailed Description
The inventor notices in the process of invention that:
the goal of wired network communication and wireless network communication is to have larger and larger bandwidth and higher speed. Wireless communication is from GSM to 5G, with up to 100 Mbps. From simple voice, text transfer to various rich media. The current 4G network can carry various services such as voice, text, pictures, video, live broadcast and the like. Even other wireless technologies, including bluetooth, WiFi, etc., are increasingly capable of carrying communications of various rich media.
However, for the digital radio system, due to the limitation of wireless spectrum resources, only communication can be performed on a narrow spectrum, the bandwidth of the digital interphone is only 25k, only voice communication can be performed, and voice is compressed and transmitted. That is, the narrowband wireless communication system can only transmit simple text messages, but cannot transmit information such as voice, pictures, video and the like.
The following is a specific analysis.
Fig. 1 is a schematic diagram of a broadband network with a central server, as shown in fig. 1, a prior art communication technical scheme is as shown in fig. 1, where a user a and a user B communicate with each other through a centralized server, including voice, text, pictures, video, and the like. Most APP applications today are in this mode, including QQ, WeChat, WhatsAPP, Facebook, and so on.
Fig. 2 is a schematic diagram of a wireless narrowband communication system, and as shown in fig. 2, data transmission stations use narrowband Radio waves (Radio waves) for data transmission, and the wireless narrowband communication system and the data transmission stations often only transmit characters. The data transmission radio station transmits characters through a narrow-band wireless communication system, and is mainly applied to industries such as petroleum, mines and the like.
However, each technology has its application scenario, and different technologies are used for different application scenarios, and the communication requirements of people are met as much as possible by technical combination. Although wireless mobile communication is long-distance and wide-range, a narrowband wireless communication system is widely used in many situations and is responsible for important communication tasks.
For example, in suburbs, oil fields, mines where there is no operator network, walkie-talkies can satisfy person-to-person voice communications. The data transmission radio station can meet digital transmission, and production parameter monitoring of oil fields and mines is realized. When the mobile internet is developed into the internet of things, the narrow-band wireless communication system is widely applied.
The inventor has realized that a narrow-band wireless communication system has the disadvantage that it can satisfy person-to-person voice communication, but only voice and not character and picture transmission.
For another example, when the mobile internet evolves to the internet of things, the following steps are faced: 1. the Internet of things is a decentralized network, and information is not stored and forwarded centrally; 2. the bandwidth of the internet of things is low, usually 2kbs, and it is difficult to transmit pictures and voice.
Based on this, the embodiment of the present invention provides a scheme capable of performing text communication and voice communication in a narrow band, and combines widely used terminal devices such as mobile phones to implement a system capable of performing transmission of text voice and the like in a long distance without an operator and in a low bandwidth. Thus, even in a suburb, a mine, a desert, a mountain, or the like where there is no operator network, more functions than an intercom can be realized, and the operation and deployment are easier than those of a digital transmission station. The method can be used in disaster areas with damaged operator networks and can be used for disaster relief communication.
The following describes embodiments of the present invention with reference to the drawings.
In the process of description, the implementation of the electronic device and the terminal for sending and receiving information will be described, and then, an example of the implementation of the four will be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such description does not mean that they must be implemented in cooperation or separately, and actually, when the electronic device and the terminal for transmitting information are implemented separately from the electronic device and the terminal for receiving information, they solve the problems of their own sides, and when they are used in combination, a better technical effect is obtained.
The following describes an environment for implementation.
A plurality of electronic devices form a decentralized communication network in a self-organizing manner, wherein decentralized means that each electronic device has a highly autonomous characteristic in a system with a plurality of electronic devices. The electronic devices can be freely connected with each other to form a new connecting unit. Any one electronic device may become a staging center, but does not have mandatory central control functions. The influence between the electronic devices forms a nonlinear causal relationship through the network. This open, flattened, equal system phenomenon or structure is referred to as decentralization.
