Method of managing, in a telecommunication network, user data of a user who may move from a base work area associated with a base exchange to another work area associated with another exchange

摘要

A method of managing, in a telecommunication network, user data of a user who may move from a base work area associated with a base exchange which comprises a base memory to another work area associated with another exchange which comprises another memory, independent of whether or not the user is communicating. The method comprises effecting a coupling between the base memory and the another memory when the user moves from the base work area to the another work area; copying a largest portion of the user data stored in the base memory and storing the copied data in the another memory via the coupling, the user data stored in the base memory remaining available for further copying, and changes to be made in the user data taking place both in the base memory and in the another memory. The copied portion of the user data stored in the another memory is inspected for correctness with respect to the user data stored in the base memory and, in the event of correctness of the copied portion of the user data, the portion of the user data stored in the another memory is made available for further copying. Changes to be made in the data take place only in the another memory, and the copied portion of the user data stored in the base memory thereafter becomes unavailable for further copying.
