The embodiment of the invention discloses a connection management method and device based on a narrowband Internet of Things. According to the technical scheme provided by the embodiment of the invention, when the mobile Internet of Things terminal needs to switch the gateway, downlink data needing to be sent to the mobile Internet of Things terminal are stored firstly, the downlink data are sentto a first target gateway needing to be switched by a mobile Internet of Things terminal, and after the first target gateway detects the access of the mobile Internet of Things terminal, the receiveddownlink data are sent to the mobile Internet of Things terminal, when the mobile Internet of Things terminal is not connected to the first target gateway, a second target gateway accessed by the mobile Internet of Things terminal is redetermined, the downlink data are sent to the second target gateway, and the downlink data are sent to the mobile Internet of Things terminal by the second target gateway. Therefore, the data can be correctly sent to the mobile Internet of Things terminal after the gateway is switched, the situation that downlink data cannot be correctly sent in the gateway switching process of the mobile Internet of Things terminal is reduced, and the data transmission quality is improved.
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.
