Abstract

The invention discloses a method, device and system for realizing information intercommunication under a SCEF scene, and relates the field of the internet of things. The SCEF device receives the firstinformation, performs the information type conversion on the first information to obtain the second information, and sends the second information to a receiver, wherein the type of the first information is one in a NB-IoT non-IP data packet and a short message, the type of the second information is another in the NB-IoT non-IP data packet and the short message. By performing conversion between information in two different types of the NB-IoT non-IP data packet and the short message, the NB-IoT short message function can be realized under the situation that the NB-IoT terminal is unnecessary to receive the short message in an attached way in a circuit domain when an operator develops the NB-IoT network operation, and the message transmission efficiency is guaranteed.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a method, device and system for realizing information intercommunication in a SCEF scenario. Background technique [0002] NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) has become an important branch of the Internet of Things. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network, thereby effectively reducing deployment costs and achieving smooth upgrades. [0003] At present, for the short message requirements of NB-IoT, two schemes are given in the 3GPP specification: the SGs scheme and the SGd scheme, but both have corresponding limitations, among which: [0004] 1) The SGs solution is suitable for G / U network circuit domain solutions, but not suitable for C network operators. [0005] 2) The SGd solution is applicable to operators with...
