Research And Implementation Of Common Service Entity System Based On OneM2M

With the development of the Internet of Things,the era of Internet of Things has gradually shifted from the theoretical level to the application level,selecting an appropriate standard and placing it from the theoretical level to the application level has become the most important part of current research.This paper uses the standardization oneM2M open source agreement and does CSE service system research and development.The main work is as follows:(1)Designed and implemented MQTT communication model to access oneM2M.By analyzing and researching the communication protocol and how to bind the communication protocol and the oneM2M protocol,the device can be accessed to the CSE platform through MQTT and collect the information data.(2)Reconstructed the original CSE system,modified the original basic services,proposed new basic services and strengthened the functional system of the entire CSE platform,so as to make the whole oneM2M standard more perfect.(3)Aiming at the new CSE platform,a new intelligent reminding method based on CSE platform is proposed,which can receive the intelligent reminder message from the network server and remind the user to complete the corresponding task according to the intelligent reminder message,thus providing users with great convenience,effectively enhance the user experience.The experiment builds a new CSE system,realizes the basic service of CSE.The new equipment can not only access through the original HTTP protocol,but also can access through multi-platform MQTT protocol and meanwhile verifies the validity of each module.The oneM2M standard after the expansion is more complete and can be more adapted to the development of the Internet of Things and applied to a more specific actual scene,laying a solid foundation for the unification of the IoT platform.
