5.4.3.11 +CUSD - unstructured supplementary service data

+CUSD – unstructured supplementary service data

Execute command

AT+CUSD = <n>,[<str>]

Enables /disables the unstructured service data reporting.

Parameters:

<n>: is used to disable/enable the presentation of an unsolicited result code:

+CUSD: <m>[,<str>,<dcs>] to the TE.

<n>:

<n> = 0 - disable the result code presentation in the DTA

<n> = 1 - enable the result code presentation in the DTA

<dcs> indicates which alphabet is used (Data Coding Scheme),refer to command

Select TE Character Set +CSCS

<str> - USSD-string (when <str> parameter is not given, network is not

interrogated):

- if TE character set other than "HEX": ME/TA converts GSM alphabet into current

TE character set according to rules of GSM 07.05

- if TE character set is "HEX": ME/TA converts each 7-bit character of GSM

alphabet into two IRA character long hexadecimal number (e.g. character ? (GSM

23) is presented as 17 (IRA 49 and 55))

-if<dcs> indicates that 8-bit data coding scheme is used: ME/TA converts each 8-bit

octet into two IRA character long hexadecimal number (e.g. octet with integer value

42 is presented to TE as two characters 2A (IRA 50 and 65))

<m>:

<m> = 0 - no further user action required, hence network initiated USSD-Notify, or

no further information needed after mobile initiated operation.

<m> = 1 - further user action required, hence network initiated USSD-Request, or

further information needed after mobile initiated operation

<m> = 2 - USSD terminated by the network

<m> = 3 - other local client has responded

<m> = 4 - operation not supported

<m> = 5 - network time out

Note: only mobile initiated operations are supported.

Warning: In case of successful mobile initiated operation, DTA waits the USSD

response from the network and sends it to the DTE before the final result code. This

will block the AT command interface for the period of the operation.

Read command

AT+CUSD?

Reports the current value of the parameter <n>

Write command

Test command

AT+CUSD=?

Reports the supported values for the parameter <n>:

<n> = 0 - result code presentation in the TA disabled

<n> = 1 - result code presentation in the TA enabled
