国际移动用户识别码（IMSI） International Mobile Subscriber Identity
国际上为唯一识别一个移动用户所分配的号码。
从技术上讲，IMSI可以彻底解决国际漫游问题。但是由于北美目前仍有大量的AMPS系统使用MIN号码，且北美的MDN和MIN采用相同的编号，系统已 经无法更改，所以目前国际漫游暂时还是以MIN为主。其中以O和1打头的MIN资源称为IRM(International Roaming MIN)，由IFAST (International Forum on ANSI-41 Standards
Technology)统一管理。目前联通申请的IRM资源以09打头。可以看出，随着用户的增长，用于国际漫游的MIN资源将很快耗尽，全球统一采用
IMSI标识用户势在必行.
IMSI共有15位，其结构如下：
MCC+MNC+MIN
MCC：Mobile Country Code，移动国家码，共3位，中国为460;
MNC:Mobile Network Code，移动网络码，共2位，联通CDMA系统使用03，一个典型的IMSI号码为460030912121001;
MIN共有10位，其结构如下：
09+M0M1M2M3+ABCD
其中的M0M1M2M3和MDN号码中的H0H1H2H3可存在对应关系，ABCD四位为自由分配。
可以看出IMSI在MIN号码前加了MCC，可以区别出每个用户的来自的国家，因此可以实现国际漫游。在同一个国家内，如果有多个CDMA运营商，可以通过MNC来进行区别.
