Application control system and application control method

To provide an application control system and application control method that ensure security when exercising operation control of application software from a service-providing server and prevent waste of communication resources even when control is exercised frequently. The application control system comprises a request-receiving part that receives request information that is transmitted from a service-providing server, which provides application software stored by the storage part of a mobile terminal, and that requests the operation control of application software; a request-judging part that judges whether or not , receipt of the request information satisfies a specified condition; and a command-transmitting part that, only in the case that receipt of the request information satisfies the specified condition, transmits to the mobile terminal a command that controls the application software.
