MIN/IMSI（国际移动台识别码） 不长于15位 3 位 2 位 IMSI MCC MNC MSIN NMSI CDMA 编号计划 移动国家码 移动台识别码 移动网号码 IMSI is the only number to identify a mobile user in a CDMA digital public land cellular mobile communication network. This code is valid to all location including a roaming area. IMSI adopts E.212 coded system. IMSI is stored in the mobile station/UIM card, HLR and VLR and transmitted on a wireless interface and MAP interface. Unicom uses MIN-based IMSI. IMSI is a 15-digit decimal number and its number structure is shown in the figure. MCC: Mobile Country Code, 460 for China. MNC: Mobile Network Code，03 used in Unicom CDMA. MSIN: Mobile Subscriber Identification Number, a 10-digit decimal number. Unicom requires that MIN is the latter 10 digits of an IMSI, namely, MSIN. For the users of in the original Great Wall network in Unicom, the MSIN number structure is shown below: 3 + H1H2H3 + ABCDEF H1H2H3 equals that in a MDN. ABCDEF is obtained after the scrambling of ABCD in a MDN. For new Unicom users, MSIN is the IRM number resource obtained by China Unicom. Unicom first uses the number segment between 09 1000 0000 and 09 4999 9999 and the number structure is as follows: 09 + M0M1M2M3 +ABCD M0M1M2M3: the same as the H0H1H2H3 in a MDN. (Note: in the number segment first used by Unicom, M0M1M2M3 may be the same as H0H1H2H3. Because the IRM number obtained by China Unicom is a discontinuous number segment. In the number segment used at a late time, M0M1M2M3 and H0H1H2H3 are different. ABCD: user number, to be obtained based on the scrambling of ABCD in a MDN in a certain mode, the scrambling mode to be defined by Unicom headquarters.
