Abstract
The invention relates to a method and an equipment of preventing the misuse of a copied subscriber identity in a mobile communication system. The use of a subscriber identity is restricted to predetermined terminals, each having an associated equipment identity in such a way that: a number of allowable equipment identities is defined for at least one subscriber identity, and a data base linking said subscriber identities and the equipment identities allowable to them is created; the terminal sends the terminal user subscriber identity and its dedicated equipment identity to the rest of the system; the rest of the system compares whether the equipment identity sent is allowable to the subscriber identity sent; as a response to the equipment identity sent being allowable to the subscriber identity sent, the use of the terminal is permitted, and otherwise the use is denied.

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.
