Description
This refers to Advice of Charge supplementary service (3GPP TS 22.024 [26] and 3GPP TS 22.086 [27]) that enables
subscriber to get information about the cost of calls. With <mode>=0, the execute command returns the current call
meter value from the MT.
The command also includes the possibility to enable an unsolicited event reporting of the CCM information. The
unsolicited result code +CCCM: <ccm> is sent when the CCM value changes, but not more that every 10 seconds.
Deactivation of the unsolicited event reporting is made with the same command.
Refer subclause 9.2 for possible <err> values.
NOTE: Advice of Charge values stored in the SIM card or in the active application in the UICC (GSM or USIM)
(ACM, ACMmax, PUCT) can be accessed with generic or restricted SIM access command (+CSIM or
+CRSM)).Those values can be more readily accessed with commands +CACM, +CAMM and +CPUC.
The Read command indicates whether the unsolicited reporting is activated or not. Read command is available when the
unsolicited result code is supported.
It is recommended (although optional) that the test command returns the supported mode values.
Defined values
<mode>:
0 query CCM value
1 deactivate the unsolicited reporting of CCM value
2 activate the unsolicited reporting of CCM value
<ccm>: string type; three bytes of the current call meter value in hexadecimal format (e.g. "00001E" indicates
decimal value 30); value is in home units and bytes are similarly coded as ACMmax value in the SIM card or in
the active application in the UICC (GSM or USIM)
Implementation
Optional.
