Set up Idle Mode Text
The proactive SIM mechanism enables the SIM to initiate actions to be handled by the G24-L.
Using this service, the SIM can inform the G24-L that it has information pending for action. The
SIM can issue a variety of protocol commands through this mechanism, for example:
• Displaying text
• Sending a short message
• Setting up a voice call to a number held by the SIM
• Setting up a data call to a number whose bearer capabilities are held by the SIM
• Sending an SS control or USSD string
• Playing a tone
• Initiating a dialogue with the user (get inkey, get input)
• Providing local information from the G24-L to the SIM
• Profile download
• Send DTMF
• Set up idle text mode
• Launch browser
• Set up event list
Menu Selection
The SIM supplies a set of possible menu entries via a proactive SIM command. The menu
selection mechanism is used to transfer the SIM application menu item selected by the user to the
SIM and then via SMS to the provider.
Call Control by SIM
When this service is activated by the SIM, all dialed digit strings, supplementary service control
strings and USSD strings are first passed to the SIM before the G24-L sets up the call, the
supplementary service operation or the USSD operation. The SIM has the ability to allow, disable
or modify the call. The STK has the ability to replace a call request, a supplementary service
operation or a USSD operation with another call, for example, a call request by the G24-L can be
diverted to a different destination.
