5.4.3.12 +CAOC - advice of charge
+CAOC – advice of charge
Execute command
AT+CAOC = <mode>
Controls the advise of charge service; the command also includes the possibility to
enable an unsolicited event reporting of the CCM information.
If unsolicited reporting is enabled DTE sends the result code
+CCCM: <acm>
when the CCM value changes, but not more than every 10 seconds.
<acm> - accumulated call meter value hexadecimal representation (3 byte)
Parameter:
<mode> = 0 - ACM (Accumulated Call Meter) read request
<mode> = 1 - disables unsolicited ACM reporting
<mode> = 2 - enables unsolicited ACM reporting
Note: +CAOC command uses the ACM of the device internal memory, not the
ACM stored in the SIM. The difference is that the internal memory ACM is reset at
power up, while the SIM ACM is reset only on user request. Advice of Charge
values stored in the SIM (ACM, ACMmax, PUCT) can be accessed with commands
+CACM, +CAMM and +CPUC.
Read command
AT+CAOC?
Reports the value of ACM in the format: +CAOC: xxxxxx.
Write command
Test command
AT+CAOC=?
Reports the supported values for <mode> parameter.
