Design And Implementation Of BIP-based OTA System For Embeded Universal Integrated Circuit Card

With the Internet of Things, the wisdom of the Earth and the concept of China has been raised, the Internet of Things has entered a development from the concept to the scale of the track, the development of Internet of Things for China's economic development has a positive significance has been clear. The most central part of the Internet of Things is the interconnection of things and objects, also known as the machine and machine interconnection, commonly known as M2M. At this stage of the machine equipment is usually no networking communication function, such as industrial machinery, vehicles, home appliances, instrumentation and so on.At the same time, embedded lot card (eUICC card) as the terminal access operator network authentication tool, as well as carrying a variety of applications, data security carrier, has become the Internet of Things (IOT) industry development key technology. M2M is increasingly using the standard card machine terminal integration products, that is embedded card to ensure the stability and security of mobile communication connections. However, due to fixed in the terminal can not be arbitrarily replaced, embedded network card number management, number configuration, number recovery is the operator needs to face a major test. The main contents of this thesis are as follows:The first one compares the two main techniques of OTA:short message mode and BIP mode, discusses the shortcomings of the current air card downloading system based on short message mode, and designs a BIP method based on short message Of the eUICC card for the open air card system architecture, to ensure the reliability of the system can effectively improve the original air card to open the transfer rate and real-time and difficult to build problems.Second, referring to 3GPP 03.48, using the custom encoding format expansion design of the BIP-based air card to open the uplink and downlink packet traffic transmission protocol to achieve the Internet of Things eUICC card remote data write and data write. Finally, the text combines the China Unicom Institute of Internet of Things R & D environment construction projects to demonstrate the way the interface to demonstrate the operators of things networking platform for things can be effectively controlled, on the Internet of things open card technology has a very important significance.
