Embodiment Construction

[0176] figure 1 This is a schematic diagram of the communication system provided by an embodiment of this application, such as figure 1 As shown, the terminal can report data to the IoT platform through the 3GPP network, and the IoT platform can transmit the data reported by at least one terminal to the application server, where the IoT platform and the application server can be connected via the Internet. The terminal and the Internet of Things platform can communicate through, for example, the LwM2M protocol, but the embodiment of the present application is not limited to this.

[0177] Among them, SCEF: used to connect the 3GPP network and the Internet of Things platform. It provides an interface for the interaction between the 3GPP network and the Internet of Things platform. It opens some capabilities in the 3GPP network to the Internet of Things platform so that the Internet of Things platform can obtain terminal information from the 3GPP network. Location information (inclu...

Abstract

The embodiment of the invention provides a communication method and device. The method comprises the steps that an Internet of Things platform obtains a historical load of a service cell of a terminal; the Internet of Things platform determines the data reporting time of the terminal according to the historical load of the service cell; and the Internet of Things platform sends the time for the terminal to report the data to the terminal. According to the embodiment of the invention, the data reporting time of the terminal is determined according to the historical load of the service cell and the time range in which the terminal can report the data; therefore, the determined data reporting time can be the time of the service cell with the lightest load in the time range in which the data can be reported, so that the terminal can report the data in a peak shifting manner, a large number of terminals can be prevented from reporting at the same time, the network congestion is avoided, and the network interest rate and the data reporting success rate are improved.

Description

Technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method and device. Background technique [0002] Narrow Band Internet of Things (NB-IoT) is a low-power wide area network with limited bandwidth, and the number of connected NB-IoT terminals at the same time is also limited. With the intelligent evolution of various vertical industries, the number of NB-IoT terminals is increasing. When it comes to street lights, gas meters, water meters, shared bicycles, manhole covers, etc., NB-IoT chips / modules will be deployed to Realize the function of NB-IoT terminals. These NB-IoT terminals may report data to the IoT platform through NB-IoT at the same time. For example, all gas meters in a cell may report at the same time, or they may report messages on the gas meter. At that time, the street lamps collectively registered the network, causing network congestion. [0003] In order to avo...
