Release 6
In GSM/UMTS, when semicolon character is given after dialling digits (or modifiers), a voice call originated to the
given address. TA returns to command state immediately (or after possible +COLP result code; refer subclause
"Connected line identification presentation +COLP"). Refer Annex G for a detailed example.
GSM/UMTS modifier characters
> (refer subclause "Direct dialling from phonebooks")
I or i (override the CLIR supplementary service subscription default value for this call; I = invocation (restrict CLI
presentation) and i = suppression (allow CLI presentation); refer subclause "Calling line identification restriction
+CLIR")
G or g (control the CUG supplementary service information for this call; uses index and info values set with command
+CCUG; refer subclause "Closed user group +CCUG")
6.3 Direct dialling from phonebooks
GSM/UMTS MT and SIM/UICC can contain phonebooks which have a phone number and an alphanumeric field for
each phonebook entry location. The use of V.250 [14] dialling command ensures that direct dialling from MT and
SIM/UICC phonebook is possible through ordinary communications software which just gives the phone number field
to be filled and then use the D command to originate the call. Available memories may be queried with Select
Phonebook Storage test command +CPBS=?, and location range for example with Read Phonebook Entries test
command +CPBR=?.
Execute commands
1. D><str>[I][G][;] originate call to phone number which corresponding alphanumeric field is <str> (if
possible, all available memories should be searched for the correct entry).
2. D>mem<n>[I][G][;] originate call to phone number in memory mem entry location <n> (available memories
may be queried with Select Phonebook Storage test command +CPBS=?; mem could be
e.g. ME).
3. D><n>[I][G][;] originate call to phone number in entry location <n> (it is manufacturer specific which
memory storage of MT, SIM/UICC and TA is used; command Select Phonebook Memory
Storage +CPBS setting is recommended to be used).
Semicolon character shall be added when voice call is originated. CLIR and CUG per call base modifiers may also be
present.
Responses
Possible error responses include +CME ERROR: <err> when error is related to MT functionality. Refer
subclause 9.2 for possible error values. Otherwise TA responses can have values defined by V.250 [14] and commands
Service Reporting Control +CR and Connected Line Identification Presentation +COLP. Detailed error report of an
unsuccessful originated call failed in a GSM/UMTS network error can be obtained with command Extended Error
Report +CEER (if implemented).
Defined values
<str>: string type value, which should equal to an alphanumeric field in at least one phonebook entry in the
searched memories; used character set should be the one selected with Select TE Character Set +CSCS
<n>: integer type memory location should be in the range of locations available in the memory used
Implementation
Mandatory when direct dialling is implemented. Also phonebook commands implementation is required.
