+CAOC – Advice of charge
Description:
This refers to the Advice of Charge supplementary service (GSM-02.24 and GSM-02.86)
which enables the subscriber to obtain information on call cost. With <mode>=0, the
command returns the current call meter value (CCM) from the ME.
If AOC is supported, the command can also enable unsolicited event reporting on CCM
information.
The unsolicited result code +CCCM: <ccm> is sent when the CCM value changes.
Deactivation of unsolicited event reporting is performed with the same command.
If AOC is supported, the Read command indicates whether unsolicited reporting is acti-
vated or not.
