name: CD
full_form: Check Digit
context: Computation of CD from the IMEI proceeds as follows: Step 1: Double the values of the odd labelled digits D1, D3, D5 ... D13 of the IMEI. Step 2: Add together the individual digits of all the seven numbers obtained in Step 1, and then add this sum to the sum of all the even labelled digits D2, D4, D6 ... D14 of the IMEI. Step 3: If the number obtained in Step 2 ends in 0, then set CD to be 0. If the number obtained in Step 2 does not end in 0, then set CD to be that number subtracted from the next higher number which does end in 0.
description: The Check Digit (CD) is a parameter used in the computation of an International Mobile Equipment Identity (IMEI). It is calculated through a series of steps involving doubling and summing specific digits of the IMEI, with the final result being either 0 or a value obtained by subtracting from the next higher number ending in 0. The CD serves as a verification mechanism to ensure the integrity of the IMEI.
explanation: CD is classified as a Parameter because it represents a calculated value used within the process of verifying an IMEI, fitting into the broader context of numbering, addressing, and identification as specified by 3GPP TS 23.003.
