ParameterTypeDescription

<snt>

Number

It indicates the requested serial number type. Depending on <snt> value, the <param_val> parameter in the information text response provides different information:

  • 0 (default value): MT serial number, typically the International Mobile station Equipment Identity (IMEI)

  • 1: International Mobile station Equipment Identity (IMEI)

  • 2: International Mobile station Equipment Identity and Software Version Number (IMEISV)

  • 3: Software Version Number (SVN)

  • 255: IMEI (not including the spare digit), the check digit and the SVN

<sn>

Number

MT serial number, typically the International Mobile station Equipment Identity (IMEI)

<imei>

String

International Mobile station Equipment Identity (IMEI). IMEI is composed of Type Allocation Code (TAC) (8 digits), Serial Number (SNR) (6 digits) and the Check Digit (CD) (1 digit).

<imeisv>

String

International Mobile station Equipment Identity and Software Version Number (IMEISV). The 16 digits of IMEISV are composed of Type Allocation Code (TAC) (8 digits), Serial Number (SNR) (6 digits) and the software version (SVN) (2 digits).

<svn>

String

Software Version Number (SVN) which is a part of IMEISV.

<imei_full

Number

International Mobile station Equipment Identity (IMEI), Check Digit and Software Version Number.

Defined values

ParameterTypeDescription

<chset>

String

Allowed characters set:

  • "IRA": International Reference Alphabet (ITU-T T.50)

  • "GSM": GSM default alphabet (3GPP TS 23.038)

  • "PCCP437": PC character set Code Page 437

  • "8859-1": ISO 8859 Latin 1 character set

  • "UCS2": 16-bit universal multiple-octet coded character set (USO/IEC10646); UCS2 character strings are converted to hexadecimal numbers from 0000 to FFFF; e.g. "004100620063" equals three 16-bit characters with decimal values 65, 98 and 99

  • "HEX": character strings consist only of hexadecimal numbers from 00 to FF; e.g. "032FE6" equals three 8-bit characters with decimal values 3, 47 and 230; no conversions to the original MT character set shall be done

  • "PCCP936": Chinese character set

  • "UTF-8": octet (8-bit) lossless encoding of UCS characters (see RFC 3629 [11]); UTF-8 encodes each UCS character as a variable number of octets, where the number of octets depends on the integer value assigned to the UCS character. The input format shall be a stream of octets. It shall not be converted to hexadecimal numbers as in "HEX" or "UCS2". This character set requires an 8-bit TA - TE interface.

Allowed values:

  • "IRA" (factory-programmed value), "GSM", "UCS2"
