27、5152535455565758596024 Decimal Representation of MEID (Informative)Annex A: Decimal Representation of MEID(Informative)This annex is informative and is not part of this standard.The MEID is a 14 digit hexadecimal value with the following format:The decimal representation is calculated as follows1:a.
28、 Separate the 14 digit hexadecimal MEID into two parts:Part 1 8 digits representing the manufacturer code (digits RRXXXXXX in thefigure).Part 2 6 digits representing the serial number (digits ZZZZZZ in the figure).b. Convert the hexadecimal value of each part into the decimal equivalent:Part 1 10 de
29、cimal digits zero filled.Part 2 8 decimal digits zero filled.If the decimal equivalent of each part is less than the number of required digits, right alignand zero fill to create the required length.c. Concatenate Part 1 and Part 2 to create an 18 digit decimal number.Example:Hex MEID = AF 01 23 45
30、0A BC DEPart 1, manufacturer code is 0xAF012345 = 2936087365Part 2, serial number is 0x0ABCDE = 00703710Therefore, the decimal representation of the MEID is 29360 87365 0070 3710.MEIDManufacturer Code Serial NumberR R X X X X X X Z Z Z Z Z Z14 13 12 11 10 9876543211This is done even if all digits ar

33、r on theexterior of an MS). The check digit is not part of the MEID and is not transmitted when the MEIDis transmitted.There are three different methods of calculating the check digit: The check digit for an MEID containing all decimal digits (i.e. an IMEI International MobileEquipment Identity assi
34、gned to a multi-mode phone) is calculated using the method describedin 3GPP TS 23.003. The check digit for an MEID containing at least one hexadecimal digit in the RR digits iscalculated using a slight modification of the ISO/IEC 7812-1:2000(E) method used in 3GPP TS23.003 (Luhn formula). The modifi
35、cation is that all arithmetic is performed in base 16 insteadof base 10. This preserves many of the desirable error detection properties of this formula. Theresult of the calculation is a single hexadecimaldigit. The check digit for the decimal representation of an MEID uses the standard (decimal) L
36、uhnformula from ISO/IEC 7812-1:2000(E) performed on all 18 digits resulting in a single decimaldigit.1B.1 Example MEID Hexadecimal Check Digit Calculation:The format of the MEID with associated hexadecimal check digit is:This calculation is for AF 01 23 45 0A BC DE (an MEID containing one or more he
37、xadecimal digitsin the RR digits). This follows the algorithm in ISO/IEC 7812-1:2000(E) with the exception that allarithmetic is in base 16: Step 1: “Double the value of alternate digits beginning with the first right-hand digit (loworder)” converts (F, 1, 3, 5, A, C, E) to (1E, 2, 6, A, 14, 18, 1C)
38、. Step 2: “Add the individual digits comprising the products obtained in Step 1 to each of theunaffected digits in the original number” produces A + (1+E) + 0 + 2 + 2 + 6 + 4 + A + 0 + (1+4)+ B + (1+8) + D + (1+C) = 64. Step 3: “Subtract the total obtained in Step 2 from the next higher number endin
39、g in 0. If thetotal obtained in Step 2 is a number ending in zero (30, 40, etc.), the check digit is 0.” Therefore,the Check Digit for this example MEID including at least one hexadeecimal digit is C (70-64).1This is done even if all digits are in the range 0-9 (i.e. the MEID is an IMEI for use with
40、 multi-mode phones).MEIDManufacturer Code Serial Number CDR R X X X X X X Z Z Z Z Z Z C14 13 12 11 10 987654321Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA-928-1123456789

This follows the algorithm in ISO/IEC 7812-1:2000(E) exactly (i.e. usingdecimal arithmetic: Step 1: “Double the value of alternate digits beginning with the first right-hand
43、digit (loworder)” converts (9,6,8,3,5,0,0,7,0) to (18,12,16,6,10,0,0,14,0). Step 2: “Add the individual digits comprising the products obtained in Step 1 to each of theunaffected digits in the original number” produces 2 + (1+8) + 3 + (1+2) + 0 + (1+6) + 7 + 6 +6 + (1+0) + 0 + 0 + 7 + 0 + 3+ (1+4) +
44、 1 + 0 = 60. Step 3: “Subtract the total obtained in Step 2 from the next higher number ending in 0. If thetotal obtained in Step 2 is a number ending in zero (30, 40, etc.), the check digit is 0.” Therefore,the Check Digit for this example decimal representation is 0.MEIDManufacturer Code Serial Nu
