At the field of mobile communication, OTA (over the air) has been successful used in the GSM network for transferring dynamic STK services, providing a wonderful solution to difficulties during the use and implementation of value–added services. However, the existing applications or value-added services which are based on OTA and STK are all reflected in the form of menu of the ME’s (Mobile Equipment) UI(User Interface), so that users need to take the initiative via ME's UI card to operate OTA procedures and applications[1]. This will reduce enthusiasm for the user use Value-added Application, and the service demand undoubtedly, thus the service providers also will lose the power. For the expansion of mobile value-added services, recently there is an innovative idea in this field: how to push the information on the Internet to mobile terminals such as mobile phone initiatively? To accomplish this function, the current technology options are mainly two as follow: the first is STK applications; and the second is WAP PUSH technology. Generally every existing ordinary SIM card application based on STK has a corresponding menu embedded in the SIM card, through which users can activate STK function modules in STM card. Obviously this ordinary application should not take the initiative to push information to complete the function. WAP PUSH technology can take the initiative to push information, but it is regrettable that most of the existing terminals and gateways WAI only support to WAP1.l, which is very weak on security. In addition, the compatibility of WAP products between the different manufacturers is not very good and there are few mobile phones that can support WAP PUSH, so that it’s not conducive to the development of mobile commerce and the user groups. For the existing communication technologies, combined with WAP PUSH, as well as the advantages of STK, a new type of active SIM cards to trigger case applications. Eventtriggered application is proposed as a new type application of proactive SIM card. Event-triggered application runs in the way that SIM card monitors some specific events from ME by its inner trigger mechanism , which may cause the application’s running, instead of users’ involvement of through the ME’s UI interface. This new reflecting form will make SIM card applications more interactive, more easily to operate, as well as provide a new mode of implementation for value-added services.
