摘要

The handset has a storage medium e.g. programmable ROM, for storing International Mobile Equipment Identity (IMEI) (21) of a mobile phone handset (1). A mobile phone handset usage system (4) controls authentication of the medium by a universal integrated circuit card (31) in order to establish a secured communication channel (6) between the medium and card, and controls the transmission of IMEI on the path towards the card. An independent claim is also included for a method of securing IMEI identification of a mobile phone handset.
