Embodiment Construction

[0047] A congestion control method provided by an embodiment of the present invention, such as figure 1 as shown, figure 1 It is a flowchart of a congestion control method provided by an embodiment of the present invention.

[0048] S101. The Internet of Things platform connects multiple terminals, and determines an uplink control mode and / or a downlink control mode of at least one of the multiple terminals.

[0049] The terminals in the embodiments of the present invention include but are not limited to IoT terminals such as sensors at the perception layer, radio frequency (RFID), and micro-electromechanical systems; the IoT platform in the embodiments of the present invention can also be an application server.

[0050] In practical application, the method of uplink and downlink message transmission between the terminal and the IoT platform is as follows: figure 2 shown. When each terminal accesses the IoT platform through LPWAN, it will send broadcast information to info...

Abstract

The embodiment of the invention discloses a congestion control method and an Internet of Things platform, and the method comprises the steps of enabling the Internet of Things platform to be connectedwith a plurality of terminals, and determining an uplink control mode and / or a downlink control mode of at least one terminal in the plurality of terminals, wherein the uplink control mode comprisesenabling the Internet of Things platform to send an online time period in which the terminal can transmit the uplink information and a gateway capable of being accessed when the terminal transmits theuplink information, to the terminal, and the downlink control mode comprises enabling the Internet of Things platform to acquire the air interface paging capability of a base station connected with the terminal, judging whether the number of terminals to be paged by the base station exceeds the air interface paging capability of the base station or not, and judging whether the downlink information is issued to the terminal or not based on the judgment result. Through the scheme of the invention, the network congestion can be reduced, the success rate of data transmission is ensured, and the transmission efficiency of the network is improved.

Description

technical field [0001] The invention relates to the field of network control, in particular to a congestion control method and an Internet of Things platform. Background technique [0002] LPWAN (Low-Power Wide-Area Network) is a wireless network with low bit rate for long-distance communication and low power consumption. This network mainly adopts star network architecture, based on The IoT base station acts as a transfer station for uplink and downlink transparent transmission. [0003] Since LPWAN is based on narrow-band Internet of Things technology, the terminal module uses asynchronous short connection for communication, which is limited by related factors such as terminal node antennas and power consumption. If terminal devices are too dense in a certain area, if the terminal Simultaneous uplink sending of packets or downlink sending of control commands will cause network congestion and result in data packet loss. Contents of the invention [0004] In view of this...
