8 Mobile Termination control and status commands
This clause includes commands for MT power, keypad, display and indicator handling. Also commands for selecting,
reading and writing of phonebooks, and setting real-time clock facilities are specified. Two commands are specified for
accessing SIM/UICC database records in a general way.
Figure 7 illustrates the effect of these commands. Command Phone Activity Status +CPAS indicates the current general
activity status of the MT. Command Set Phone Functionality +CFUN is used to set the MT to different power
consumption states. Command Enter PIN +CPIN is used to enter MT passwords which are needed before any other
functionality of the MT can be used (e.g. SIM PIN, PUK). Commands Generic SIM Access +CSIM and Restricted SIM
Access +CRSM can be used to access all data in SIM/UICC. Commands Battery Charge +CBC and Signal Quality +CSQ
are same as in TIA IS-135 [16] and they are used to query the battery charge of the MT and the current RSSI of the MT.
Command Mobile Termination Control Mode +CMEC is used to select the controlling unit of MT keypad, display and
indicators. Controlling commands for the TE are Keypad Emulation +CKPD, Display Control +CDIS and Indicator
Control +CIND. If corresponding event reporting is enabled with command Mobile Termination Event Reporting
+CMER, +CKEV is the result code of a keypad event, +CDEV is the result code of a display event, and +CIEV is the
result code of an indicator event. Phonebook commands are Select Phonebook Memory Storage +CPBS, Read
Phonebook Entries +CPBR, Find Phonebook Entries +CPBF and Write Phonebook Entry +CPBW. Additional command
Clock +CCLK can be used to control the real-time clock of the MT if available. Command Alarm +CALA sets possible
alarm clock facilities of the MT.
