Terminal application control method, device and system

The invention relates to the field of communication, and particularly relates to a terminal application control method, device and system. According to the invention, when a function of a terminal application needs to be regulated and optimized, regulation on the application function can be implemented only by issuing a configuration file to a terminal and enabling the terminal to execute a control instruction included in the configuration file, and a new version does not need to be issued to carry out regulation on the related function of the application. Particularly, in a case that an application result obtained after the terminal executes the control instruction does not reach an expected result, the control instruction is regulated and issued to the terminal again until the application result fed back by the terminal accords with the expected result so as to form a virtuous circle. Compared with a version releasing mode, such mode of carrying out regulation and optimization on theapplication function by issuing the configuration file can shorten a regulation period of the application function, improve availability of the application function and improve user experience.
