Description: This refers to the Advice of Charge supplementary service (GSM 02.24 and
GSM 02.86) that enables a subscriber to get information about the cost of
calls. With <mode>=0, the execution command returns the Current Call
Meter (CCM) value from the ME. The command also includes the possibil-
ity to enable an unsolicited event reporting of the CCM information. The
unsolicited result code +CCCM: <ccm> is sent when the CCM value
changes, but no more than every 10 seconds. Deactivation of the unsolic-
ited event reporting is made with the same command.
Read command indicates whether the unsolicited reporting is activated or
not. Read command is available when the unsolicited result code is sup-
ported.
