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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
