Soft switching system of Internet of Things and method thereof

Abstract

The invention provides a soft switching system of Internet of Things and a method thereof, and belongs to the field of Internet of Things technology. The system comprises a perception layer device or bus, an access system, a network soft switching system, a soft switching service and management system, a standardization information format, and a mobile service management terminal or a PC service management terminal. According to the invention, complexity of a perception layer in the network accessing stage is separated and shielded. On this basis, transportation and switching technology which can be standardized and suitable for Internet of Things are introduced, so problems of complexity and high accessing cost of the perception layer devices of Internet of Things in accessing stages are solved. Processing methods of identifying, distinguishing, addressing, transporting and information switching based on Internet network layer information are also introduced, so a highly practical and economical solution is provided for standardization and large-scale application of Internet of Things in network layer. According to the invention, technical cost is low, cost performance is high and the system is high in university and compatibility and large in access capacity.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an Internet of Things softswitch system and an implementation method thereof. Background technique [0002] The Internet of Things is a network information system composed of a perception layer, a network layer, and an application layer. Its essence is the Internet where everything is connected, and the essential problem to be solved is the informatization of things to things M2M and things to people M2H. With the development of the Internet of Things industry, problems are becoming more and more prominent, mainly in two aspects: [0003] First, the diversity characteristics of the perception layer determine the complexity of its network access links [0004] The perception layer is mostly based on physical, chemical, biological and other technologies and invented devices such as sensors or actuators.

AI Technical Summary

Problems solved by technology

[0004] The perception layer is mostly based on physical, chemical, biological and other technologies and invented devices such as sensors or actuators. Usually there is no unified representation and interface standard. The good thing is that in some mature and specialized application fields, the perception layer devices are usually directly or indirectly connected to a standardized field bus, but these buses are usually developed for specific field applications , is not suitable for Internetization in essence, and there is a natural lack of interaction between physical devices or different bus systems, such as the patent CN201110270902 "A Switching System and Data Processing Method for the Internet of Things", which "purposes to provide various The hardware device provides a common platform for the system", "the switching device is set between the perception layer and the network layer", and its shortcomings are also obvious: poor versatility, mainly for the specific implementation protocol of specific hardware Targeted interconnection and intercommunication adaptation processing, the degree of "Internetization" of the network is not enough, usually only suitable for internal application occasions of the LAN, the complexity of the network access link determines its high access cost, which restricts the Application, scale and standardization development of networking.

[0005] Second, the information transmission and exchange standards adopted by the Internet of Things network layer are not uniform, and the processing methods are not uniform

[0006] The current common IoT application forms are relatively simple, single, and closed. Therefore, there are no standards that developers can follow in terms of network layer information representation and processing, and the interaction between different systems is inherently insufficient. Nowadays, embedded Http The IoT applications based on client\reset API technology are usually only suitable for "jogging" and applications with low real-time requirements, and are not completely suitable for occasions that require stream data processing and real-time performance; in addition , with the expansion of the scale of the Internet of Things network, common traditional technologies are also difficult to adapt to many problems encountered in large-scale deployment of the Internet of Things network: the diversity of perception layers, low-cost access problems, and diversified user applications , platform scale and systematization, etc.

Softswitch technology is a new technology developed in the VOIP business field of the telecommunications industry in recent years, but this technology is rarely applied to other fields except the VOIP of the telecommunications industry, such as the Internet of Things and related application fields involved in the present invention, Because the traditional softswitch technology is not developed for the application of the Internet of Things, it is mainly aimed at the telecom VOIP service and related application fields. Its most basic feature is to change the call control function from the traditional circuit switching to Separated from the media gateway, the basic call control functions are realized through the software on the server or network element, including call routing, management control, connection control (session establishment, session teardown), signaling intercommunication (such as from No. 7 signaling to IP signaling), etc., such a complex softswitch system cannot be directly applied to the Internet of Things
