19.1.4 Proactive SIM
A proactive SIM provides a mechanism whereby the SIM can ask the customer
application to perform certain actions.
These actions include:
• display menu,
• display given text,
• get user input,
• send a short message,
• play the requested tone,
• set up a call,
• provide location information.
This mechanism allows SIM applications to generate powerful menu-driven
sequences on the customer application and to use services available in the network.
The commands used for this operation are:
• +STIN (SIM ToolKit Indication),
• +STGI (SIM ToolKit Get Information),
• +STGR (SIM ToolKit Give Response).
19.1.5 Data Download to SIM
Data downloading to the SIM (SMS, phonebook…) allows data or programs (Java
applets) received by SMS or by Cell Broadcast to be transferred directly to the SIM
Application.
This feature does not need any AT command. It is transparent to the customer
application.
19.1.6 Menu Selection
A set of menu items is supplied by the SIM Application ToolKit. The menu selection
command can then be used to signal to the SIM Application which menu item is
selected.
The commands used for this operation are +STIN, +STGI and +STGR.
19.1.7 Call control by SIM
The call control mechanism allows the SIM to check all dialed numbers,
supplementary service control strings and USSD strings before connecting to the
network. This gives the SIM the ability to allow, bar or modify the string before the
operation starts.
The commands used for this operation are:
• +STCR (SIM ToolKit Control Response),
• +STGR (SIM ToolKit Give Response).
