Abstract: A method is provided for supplying service to mobile stations (MS) (20) utilizing a wireless telecommunications network (A). Each of the MS has a home country and a home network and is programmed with an identifier comprising a number including a set of digits. Each identifier is one of two types including a first type of identifier that uniquely identifies its MS globally via the entire set of digits making up the identifier (e.g., a true International Mobile Station Identity (IMSI)) and a second type of identifier that uniquely identifies its MS within its home country via a subset of least significant digits making up the identifier (e.g., a Mobile Identification Number (MIN)-based IMSI). The method includes: obtaining the identifiers from MS entering the wireless telecommunications network during a study period; collecting a subset of most significant digits from each identifier obtained during the study period; compiling a list of digit patterns, each digit pattern in the list corresponding to one of the subsets of most significant digits collected; receiving identifiers from MS accessing the wireless telecommunications network; and, comparing the subsets of most significant digits of the received identifiers to the compiled list to determine which of the received identifiers are the first type and which are the second type of identifier.

Abstract translation: 提供一种利用无线电信网络（A）向移动台（MS）（20）提供服务的方法。 每个MS具有本国和家庭网络，并且被编程有包括包括一组数字的号码的标识符。 每个标识符是两种类型中的一种，包括通过构成标识符的整个数字组（例如，真正的国际移动站标识（IMSI））来唯一地唯一地标识其MS的第一类型的标识符，以及唯一地标识其第二类型的标识符 通过构成标识符的最低有效数字的子集（例如，基于移动识别码（MIN）的IMSI）在其本国国家内识别其MS。 该方法包括：在研究期间从MS进入无线电信网络的标识符获得; 从研究期间获得的每个标识符收集最有意义的数字的子集; 编辑数字模式列表，列表中的每个数字模式对应于收集的最高有效数字的一个子集; 从接入无线电信网络的MS接收标识符; 并且将所接收的标识符的最高有效数字的子集与编译的列表进行比较，以确定哪个接收到的标识符是第一类型，哪些是第二类型的标识符。
