Embodiment Construction
[0038] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.
[0039] figure 1 Shows a network topology diagram of a TSM-based M2M SIM card COS update system in an embodiment of the present invention, from figure 1 It can be seen that the system includes: IoT CTSMS management platform, database, cache server, IoT terminal and mobile gateway, among which:
[0040] Internet of Things terminal: It is embedded with an Internet of Things SIM card and has communication functions. The SIM card in the Internet of Things terminal can interact with the CTSMS management platform of the Internet of Things.
[0041] IoT CTSMS management platform: used to maintain IoT SIM card information, chip information, COS information and user information, business personnel can access the IoT CTSMS management platform through the Web to update the COS operating system of the SIM card in the IoT terminal.
[0042] The data of the Int...

The invention relates to a TSM-based M2M SIM card COS updating method and system, and belongs to the technical field of Internet of Things SIM cards, and the method comprises the following steps: an Internet of Things CTSMS management platform receives Internet of Things SIM card user information; a salesman starts a COS updating operation of the SIM card through the platform, and creates a secure channel between the Internet of Things terminal and the platform through a data short message; the platform reads the SIM card and chip information from the Internet of Things terminal through a packaging instruction, and performs legality verification; if the verification is passed, the platform assembles a new COS message and issues the new COS message to the terminal; the SIM card receives the new COS message, installs the new COS and switches the COS, and deletes the content corresponding to the old COS after successful switching; an installation result and old COS personalized data are assembled and sent to the platform; and the platform updates the COS issuing execution state, and updates the corresponding information of the user COS at the same time. According to the method and the system provided by the invention, the new COS can be safely and reliably updated to the SIM card of the Internet of Things, various card channel protocols are supported, and the method and the system can be compatible with updating of different SIM cards.
Description
technical field [0001] The invention belongs to the technical field of SIM cards of the Internet of Things, and specifically relates to a method and system for updating a COS of an M2M SIM card based on TSM. Background technique [0002] According to industry data, although the cellular network accounts for only a small portion of the total Internet of Things connections (6% in 2015 and 14% by 2025), based on the explosive growth of the total Internet of Things connections, cellular networks The number of IoT connections will more than triple between 2018 and 2025, reaching 8.4 billion by 2020. Among them, the proportion of embedded M2M is increasing. By the end of 2020, the number of mobile Internet of Things connections will exceed 1.08 billion. It is estimated that 820 million new users will be added in 2021-2022, of which embedded M2M will account for 21%. [0003] M2M services are distributed in various complex scenarios in various industries, posing new challenges to ...
