Problems solved by technology

However, the internal design of NB-IOT's low power consumption and low cost is based on technologies such as PSM (Power Saving Mode, power saving mode) and eDRX (Enhanced Discontinuous Reception, enhanced non-connection reception). The nature of sleep makes the signaling not reachable at any time and the communication delay is long. Devices that use NB-IOT technology to communicate, including transmitting devices and receiving devices with built-in NB-IOT chips, need to communicate when the transmitting device moves past. When the receiving device (monitoring point / data collection point) is used, the NB-IOT chip of the transmitting device will be in a long sleep and cannot complete normal communication.

Embodiment 1

[0033] see figure 1 , is a schematic structural diagram of an embodiment of a communication system based on the cellular narrowband Internet of Things provided by the present invention.

[0034] In a first aspect, an embodiment of the present invention provides a communication system based on a cellular narrowband Internet of Things, including: a user terminal 10 and a data receiving device 20; the user terminal 10 includes a first chip 11 based on a cellular narrowband Internet of Things (NB-IOT chip) and data cache module 12;

[0035] The data receiving device 20 is configured to continuously send out data reading requests within the signal coverage area;

[0036] The user terminal 10 is configured to extract communication data from the data cache module 12 and send it to the data receiving device when the user terminal 10 is located within the signal coverage and receives the data reading request; wherein, The communication data is the data for updating the data cache mod...

Embodiment 2

[0047] see figure 2 , is a schematic structural diagram of another embodiment of the communication system based on the cellular narrowband Internet of Things provided by the present invention. The communication system includes: a user terminal 10 and a data receiving device 20; the user terminal 10 includes a first chip 11 and a wireless wake-up circuit 13 based on cellular narrowband Internet of Things;

[0048] The data receiving device 20 is configured to continuously send out data reading requests within the signal coverage area;

[0049] The wireless wake-up circuit 13 is configured to trigger and generate a wake-up signal when the user terminal 10 is within the signal coverage area upon receiving the data read request, and transmit the wake-up signal to the first chip 11;

[0050] The first chip 11 is configured to switch from the sleep mode to the communication mode when receiving the wake-up signal, extract data according to the data read request and transmit it to ...

Embodiment 3

[0058] see image 3 , is a structural schematic diagram of another embodiment of the communication system based on the cellular narrowband Internet of Things provided by the present invention. The communication system includes: a user terminal 10, a data receiving device 20, and a cloud computing server 30; the user terminal 10 includes a timing wake-up module 15 and a first chip 11 based on cellular narrowband Internet of Things;

[0059] The timing wake-up module 15 of the user terminal 10 is used to control the first chip 11 to switch from the sleep mode to the communication mode when the accumulated time of the first chip 11 in the sleep mode is greater than the set sleep time. When the first chip 11 is in the communication mode longer than the active time, and the user terminal 10 is communicating with the outside, the first chip 11 is controlled to switch from the communication mode to the sleep mode after the two parties complete the entire communication process; When ...

Abstract

The invention discloses multiple cell-based narrowband Internet of things communication systems. One cell-based narrowband Internet of things communication system comprises a user terminal and a data receiving device, wherein the user terminal comprises a cell-based narrowband Internet of things first chip and a data cache module; the data receiving device is used for continuously externally transmitting a data reading request in a signal coverage range; the user terminal extracts the communication data from the data cache module and transmits the communication data to the data receiving device when the user terminal is located in the signal coverage range and the data reading request is received; and the communication data are data for updating the data cache module when the cell-based narrowband Internet of things first chip of the user terminal is switched to a communication mode from a sleep mode. By adopting the embodiment of the invention, reachable communication data can be ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system based on a cellular narrowband Internet of Things.
