CA 2227144

The automaton used in the invention has 2n states, running from 0 to 2n-1. When the automaton is between the state 0 (302) and state n-1 (308), the WS authentication scheme is performed. But, when the automaton is between state n (310) and 2n-1 (316), the S authentication scheme is performed. The switching between the authentication schemes increases the efficiency of the overall authentication functions in the mobile communication system thereby reducing the number of database accesses needed to authenticate a registration or a call.

L'automate appliqué dans le cadre de cette invention possèdes 2n états, s'échelonnant de 0 à 2n-1. Lorsque l'automate se situe entre l'état 0 (302) et l'état n-1 (308), on procède au mode d'authentification WS, lorsqu'il se situe entre un état n (310) et 2n-1 (316), on procède au mode d'authentification S. La commutation entre les modes d'authentification accroît la productivité de l'ensemble des fonctions d'authentification et, partant, réduit le nombre d'accès à des bases de données indispensables pour authentifier un enregistrement ou un appel.
