Test system for SIM card popularization application

Abstract

The invention relates to a test system for the promotion and application of an SIM card. The test system comprises a microprocessor (10), an SIM card connector (20) electrically connected with the microprocessor (10), a manual control module (30) and a state indication module (40). Test software which is customized according to various functions of the SIM card to be promoted and applied is embedded in the microprocessor (10), and can achieve the startup flow of an analog mobile telephone. During the simulated startup test, the microprocessor (10) operates the test software automatically, and sends a series of commands in conformity with the GSM or CDMA standards to the tested SIM card. Whether the promoted and applied functions are compatible with the tested SIM card is determined according to the execution state and the returned results. Compared with the prior art, the test system can prevent the SIM card from being damaged unnecessarily; the SIM card is promoted and applied successfully; the risks of developers and users are reduced.

Description

technical field [0001] The invention relates to a test system of a SIM card (Subscriber Identity Model card of mobile communication technology), in particular to a test system aiming at popularizing and applying the SIM card. Background technique [0002] With the development of technology and the popularity of ordinary mobile phone (referred to as "mobile phone") applications, there are more and more popularization and application of SIM cards in mobile phones, which not only opens up value-added business space for developers and operators, At the same time, it also provides a lot of convenience to the users. For example, by adding an ultra-thin bridging smart card between the mobile phone card slot and the SIM card, the mobile phone can have functions such as payment, access control, and capacity expansion without changing the mobile phone and SIM card. These promotional applications need to make corresponding changes on the card body of the original SIM card during imple...

AI Technical Summary

Problems solved by technology

There will inevitably be a risk in this way. After the card body modification to the user's SIM card is completed, it is found that the function of the promoted application cannot be compatible with the original SIM card (that is, it cannot be used) during the trial.

This will cause losses to both developers and users

In the prior art, there is no test system that can cooperate with the promotion and application of the SIM card, that is, before changing the SIM card body, it can be tested to determine whether the function to be promoted and applied is compatible with the SIM card, and then perform corresponding tests after passing the test. Changes to avoid the above situation from happening
