Data transmission management system, a mobile device and a server used therein

摘要

A data transmission control system includes a server configured to store an application program having a data area in which transmission control information containing a threshold value used to detect abnormal data transmission is stored and to allow the application program to be downloaded in response to a request, and a mobile device that downloads the application program from the server. The mobile device comprises a management table recording the transmission control information extracted from the downloaded application program; a counter configured to count a number of messages or traffic volume per unit time; a detector configured to compare the counted value with the threshold value contained in the transmission control information to detect abnormal data transmission; and a transmission regulating unit configured to restrict data transmission upon detection of the abnormal data transmission.
