In order to improve service quality, attract users, and then be invincible in the fierce market competition, network operators must constantly introduce new types of services. The short message service is used to meet the needs of operators and mobile users. However, with the continuous increase of mobile users and the continuous increase of short message traffic, higher requirements are bound to be placed on the stability and processing capacity of the short message center system.

In addition, the structure of the short message initiated by the mobile phone is relatively simple, and each time it is sent, it is the same message, and various parameters cannot be adjusted, and the system cannot be well tested for various abnormal conditions, and the purpose of various abnormal tests cannot be achieved. . Moreover, the number of test mobile phones is limited, at least two or three, so it is impossible to test the system with large traffic, and it is impossible to meet the requirements of testing the processing capacity of the short message center system. In addition, the types of messages initiated by the mobile phone cannot be flexibly adjusted, and messages cannot be sent in different proportions according to various types of messages. Due to the limitations of the above-mentioned various conditions, the existing test environment cannot conduct real and effective stability and performance tests on the short message center system. Therefore, it is imperative to find a system that constructs various conditions and simulates the real environment to test the short message center system. With this system, the above-mentioned problems can be solved and the work efficiency can be greatly improved.
