| ----
| |
| The command allows control of the Unstructured Supplementary Service Data (USSD) according to 3GPP TS 22.090. Both network and mobile initiated operations are supported.
| |
| | |
| Parameter '''<mode>''' is used to disable/enable the presentation of an unsolicited result code. The value '''<mode>'''=2 is used to cancel an ongoing USSD session. For an USSD response from the network, or a network initiated operation, the format is: '''+CUSD: <status>[,<rspstr>,[<dcs>]]'''.
| |
| | |
| When '''<reqstr>''' is given, a mobile initiated USSD string or a response USSD string to a network initiated operation is sent to the network. The response USSD string from the network is returned in a subsequent '''+CUSD''' URC.
