ENHANCED DATA ACCESS TECHNIQUE FOR USER DATA FROM A HOME SUBSCRIBER SERVER

摘要

There are provided measures for an enhanced data access technique for user data. Such measures exemplarily comprise detection of unfeasibility of a data access of data of a specified user at a home subscriber server using a mobile subscriber telephone number due to ambiguity of the mobile subscriber telephone number as a user identity and unavailability of an international mobile subscriber identity as a private identity of the specified user, and selection of a process for enabling the data access of data of the specified user at the home subscriber server using the mobile subscriber telephone number on the basis of a necessity of the international mobile subscriber identity as a private identity for the data access of data of the specified user.
