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

摘要

A data transmission control system includes a server (3) configured to store an application program (2) having a data area (21) 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 (5) that downloads the application program (2) from the server (3). The mobile device (5) comprises a management table (522) recording the transmission control information (21) extracted from the downloaded application program (2); a counter configured to count a number of messages or traffic volume per unit time (542); a detector configured to compare the counted value with the threshold value contained in the transmission control information to detect abnormal data transmission (543); and a transmission regulating unit configured to restrict data transmission upon detection of the abnormal data transmission (544).
