The embodiment of the present application discloses a connection management method and device based on NB-IoT. The technical solution provided by the embodiment of the present application saves the downlink data that needs to be sent to the mobile IoT terminal when the mobile IoT terminal needs to switch gateways, and sends the data to the first target gateway that the mobile IoT terminal needs to switch to. For downlink data, the first target gateway sends the received downlink data to the mobile IoT terminal after detecting the access of the mobile IoT terminal, and when the mobile IoT terminal is not connected to the first target gateway , re-determine the second target gateway that the mobile IoT terminal is connected to, and send downlink data to the second target gateway, and the second target gateway sends the downlink data to the mobile IoT terminal to ensure that the data can be sent correctly After reaching the mobile IoT terminal after switching the gateway, it reduces the situation that the downlink data cannot be delivered correctly during the gateway switching process of the mobile IoT terminal, and improves the quality of data transmission.
Description
technical field [0001] The embodiments of the present application relate to the technical field of the Internet of Things, and in particular to a connection management method and device based on the narrowband Internet of Things. Background technique [0002] Existing narrowband IoT systems generally access various IoT terminals, such as sensor devices and user terminals, through an IoT gateway. The IoT gateway communicates with the cloud server via the Internet to realize data transmission between the IoT terminal and the cloud server. [0003] For IoT terminals with strong mobility, in order to ensure the communication quality between IoT terminals and IoT gateways, the connected IoT gateways will be switched according to the real-time mobile locations of IoT terminals. The situation that the downlink data sent to the IoT terminal cannot be successfully delivered is not conducive to the correct delivery of data.
