Detailed Description

This structure represents some meaningful parts of a decoded and/or to be encoded GSM 04.80 message.

Field Documentation

invoke_id

uint8_t ss_request::invoke_id

GSM TS 04.80, section 3.6.3 "Component ID tag" The term Component ID refers to the Invoke ID or the Linked ID.

Referenced by gsm0480_decode_ussd_request(), parse_ss_invoke(), and parse_ss_return_result().

opcode

uint8_t ss_request::opcode

GSM TS 04.80, section 3.6.4 "Operation code" See GSM0480_OP_CODE_* for possible values.

Referenced by parse_ss_invoke(), and parse_ss_return_result().

ss_code

uint8_t ss_request::ss_code

GSM TS 04.80, section 4.4.3.9 "ss-Code" The ss-Code identifier refers to the code which identify a supplementary service or a group of supplementary services.

Referenced by parse_ss_for_bs_req().

transaction_id

uint8_t ss_request::transaction_id

GSM TS 04.80, section 3.3 "Transaction identifier" See GSM TS 04.07, section 11.2.3 for details.

Referenced by gsm0480_decode_ss_request(), and gsm0480_decode_ussd_request().

ussd_data

uint8_t ss_request::ussd_data[GSM0480_USSD_OCTET_STRING_LEN]

Represents the data of either an INVOKE, either a RETURN_RESULT component 'as is'.

Useful when decoding is not supported or not desired.

Shall be always followed by its length (in bytes) and DCS (Data Coding Scheme).

Referenced by parse_process_uss_data(), and parse_process_uss_req().

ussd_data_dcs

uint8_t ss_request::ussd_data_dcs

Referenced by parse_process_uss_data(), and parse_process_uss_req().

ussd_data_len

uint8_t ss_request::ussd_data_len

Referenced by parse_process_uss_data(), and parse_process_uss_req().

ussd_text

uint8_t ss_request::ussd_text[GSM0480_USSD_OCTET_STRING_LEN]

A rudiment of deprecated 'ussd_request' structure.

Represents the data of either an INVOKE, either a RETURN_RESULT component, encoded as ASCII in case if DCS is 0x0f (i.e. decoded by the code itself), otherwise raw bytes 'as is'.

Referenced by gsm0480_decode_ussd_request(), parse_process_uss_data(), parse_process_uss_req(), and parse_ss().
