Problems solved by technology
However, due to the use of relatively backward spread spectrum technology (used in the third generation of mobile communications 20 years ago), the performance of the design is greatly reduced in complex environments, such as the coverage in urban environments is generally lower than 2km
However, narrowband technologies such as SIGFOX have poor anti-interference ability
In particular, the existing frame structure cannot achieve complete synchronization of uplink and downlink, resulting in resource waste and efficiency reduction in multi-carrier and multi-system communication
[0004] Since many IoT applications are vertical applications, traditional cellular networks are carried on top of the IP data network when supporting IoT, which is not efficient. For example, in an application that reports dozens of bits each time, it is very wasteful

The invention discloses a wide-area Internet of Things communication system architecture and a communication method. The wide-area Internet of Things communication system architecture comprises a terminal device layer, a wide area Internet of Things communication (WIoTa) network layer and a service provider network layer, wherein the terminal device layer comprises at least one terminal device ofthe Internet of Things, and the terminal device communicates with an access point of the WIoTa network layer; the WIoTa network layer comprises at least one access point, at least one service providergateway and a central management database server; the access point is responsible for interacting with the terminal device and also responsible for interacting with the service provider gateway; theservice provider gateway is used for deciding which service provider network interface server of the service provider network layer the data packet of the terminal equipment is to be transmitted to, and the central management database server is used for storing data; the service provider network layer comprises at least one service provider; the service provider comprises a network interface server and an application server; and the network interface server communicates with the application server.
Description
technical field [0001] The present invention relates to the technical field of Internet of Things communication, in particular to a wide-area Internet of Things communication system architecture and a communication method. Background technique [0002] With the explosive growth of IoT applications, IoT communications are also booming. The short-distance IoT technology is relatively complete, but the wide-area IoT technology with broad application prospects is still gaining momentum. At present, in terms of IoT wide-area communication technology, there are two camps, the operator camp and the unlicensed spectrum camp. The unlicensed spectrum camp has been deeply involved in different industries for many years, and many companies have excellent performance in different fields, such as sigfox and lora systems. The operator camp quickly launched the NB-IoT protocol at the end of 2016, striving to gain a share in this field. NB-IoT is based on the cellular mobile communication...
