Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a cellular number management system of an eSIM module. Background Art

[0002] The embedded subscriber identity module, or eSIM (Embedded Subscriber Identity Module), is a software and hardware processing module built into a mobile communication device that is used to simulate the functions of a physical telecommunications card (such as a SIM card, UICC card, etc.). The module simulates the telecommunications card I / O communication protocols and instruction sets of various mobile communication networks (such as 4G networks, 5G networks, LTE networks, etc.) through a built-in embedded operating system. At the same time, it also uses the built-in data storage space to store a series of configuration files for mobile communication network cellular numbers (i.e., mobile phone numbers). These configuration files are equivalent to the telecommunications card files of various mobile communication network telecommunications cards. After the eSIM module is built into the mobile communication device, the user can change the number by updating the configuration file, thus avoiding the cumbersome process of plugging and unplugging the physical card when changing the number.

[0003] At present, most of the conventional processing mechanisms for changing the number of eSIM modules are implemented by remote SMS. For example, when a remote server (referred to as server A) confirms that the eSIM module (referred to as module C) on a mobile communication device (referred to as device B) needs to be changed, it will send a remote management SMS (referred to as SMS D) with a number deletion instruction (or deletion instruction) to device B. Device B will transparently transmit SMS D to module C. After receiving SMS D, module C will delete the old number configuration file stored locally. Once module C completes the number deletion operation, it will cause device B to fail to stay on the network. At this time, device B will connect to server A through other connection methods (such as accessing the Internet through WiFi or network cables) and obtain the card writing script of the new number configuration file from server A to write the card to module C and reset the device after the card writing is completed. After the reset, device B can log on to the network based on the new number configuration file on module C. Obviously, the success rate and processing efficiency of the conventional processing mechanism are closely related to the efficiency of sending and receiving SMS D. However, during the actual application process, we found that due to various factors such as the signal quality of the mobile communication network and the service quality of the SMS service gateway, the efficiency of sending and receiving SMS D is not very ideal. In other words, the success rate and processing efficiency of the eSIM module number changing mechanism that only relies on remote SMS need to be further improved. Summary of the invention
