:''Not to be confused with'' USAT (United States Army Transport) USIM Application Toolkit (USAT) is the equivalent of STK for 3G networks.〔http://www.gemalto.com/techno/stk/〕 USAT enables the USIM to initiate actions which can be used for various value-added services delivered over mobile devices. USAT takes advantage of the multiapplication environment of 3G devices by not activating until a specific application has been selected, unlike STK which is activated at startup.〔(Mobile SIM Tool Kit )〕 Some functions are card related rather than application related.〔http://www.3gpp.org/ftp/tsg_t/WG3_USIM/TSGT3_10/docs/t3-99346.doc〕 USAT is defined in standard 3GPP 31.111 for 3G.〔 ==More information== For more information see STK, the equivalent of SAT for 2G. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「USIM Application Toolkit」の詳細全文を読む スポンサード リンク
