ABSTRACT:
The present invention relates to a method and an apparatus for performing a location update of a user equipment in a mobile network, wherein it is decided on the basis of the result of a negotiation with an old location register whether to use an identification information obtained from the old location register or to retrieve the identification information from a user database. Accordingly, whenever a fall-back to a protocol version not supporting the required identification information is determined, the identification information is retrieved from the user database, to thereby guarantee that the correct identification information is used in the new location register. The identification information may comprise security or authentication parameters.
