Abstract

Cette invention se rapporte à un procédé servant à attribuer un masque de code long public (PLCM) à un terminal mobile dans un réseau de communication mobile. Ce procédé consiste à attribuer un premier type de masque PLCM, lorsque le réseau de communication mobile attribue le masque PLCM au terminal mobile, et à attribuer un second type de masque PLCM, lorsque le masque PLCM du terminal mobile est déterminé sur la base d'un numéro de série électronique (ESN) associé au terminal mobile.
