Embodiment Construction
[0030] The basic idea of the present invention is: use the linear fixed-length file of the user identification card to store the business data of the relevant Internet of Things application, and the terminal controls to read the business data that needs to be pre-read into the pre-reading of the terminal when it is turned on or needed. When a read operation occurs later, read from the terminal's preset storage area; when writing, temporarily write it into the terminal's preset storage area, and when the writing condition is met (such as when the computer is turned off, or timer timing time), the service data in the preset storage area of the terminal is synchronized to the linear fixed-length file in the subscriber identification card. By this method, the interactive response time of some industrial applications can be shortened, and the erasure of the subscriber identification card can be reduced. Write times, thereby prolonging the life of the user identification card, me...

The invention discloses a method and a device for reducing the number of user identification card erasing and writing operations, which are used to solve the problem of frequent erasing and writing of user identification cards by Internet of Things services in the Internet of Things environment, resulting in too short service life of user identification cards and poor business operation. fluency issues. The present invention utilizes the linear fixed-length files that are not often used by the user identification card in some businesses, and the pre-reading fixed-length files enter the terminal storage area, thereby improving the running speed of the business system, and ensuring the erasure and rewriting during the operation of the business system. The operation of the user identification card adopts the method of storing in the terminal memory card first, and then uniformly erases and writes the user identification card when the writing conditions are met, which effectively reduces the number of accesses to the user identification card and prolongs the service life of the user identification card. service life.
Description
technical field [0001] The invention relates to the technical field of machine type communication terminals, in particular to a method and a device for reducing the number of user identification card erasing and writing operations. Background technique [0002] The Internet of Things, as an important part of the emerging high-tech industry, has been regarded as one of the key technologies for coping with the economic crisis and revitalizing the economy by countries all over the world. IoT services can be widely applied to many industries, including vehicles, electric power, finance, environmental protection, petroleum, personal and corporate security, hydrology, military, fire protection, meteorology, coal, agriculture and forestry, elevators, etc. According to experts' estimates, in the next few years, the Internet of Things business will rapidly enter many industries, and the number of users will also grow rapidly. It is estimated that by the end of 2012, the number of Int...
