Title (EN) MANAGEMENT OF SECURITY CONTEXTS AT IDLE MODE MOBILITY BETWEEN DIFFERENT WIRELESS COMMUNICATION SYSTEMS
(FR) GESTION DE CONTEXTES DE SÉCURITÉ EN MOBILITÉ EN MODE REPOS ENTRE DIFFÉRENTS SYSTÈMES DE COMMUNICATION SANS FIL
Abstract:
(EN) There is provided a solution for managing security contexts at idle mode mobility of a wireless communication device between different wireless communication systems including a first wireless communication system and a second wireless communication system. The first wireless communication system is a 5G/NGS system and the second wireless communication system is a 4G/EPS system. The solution is based on obtaining (S1) a 5G/NGS security context, and mapping (S2) the 5G/NGS security context to a 4G/EPS security context.
(FR) L'invention concerne une solution permettant de gérer des contextes de sécurité en mobilité en mode repos d'un dispositif de communication sans fil entre différents systèmes de communication sans fil comprenant un premier système de communication sans fil et un second système de communication sans fil. Le premier système de communication sans fil est un système 5G/NGS et le second système de communication sans fil est un système 4G/EPS. La solution est basée sur l'obtention (S1) d'un contexte de sécurité 5G/NGS, et la mise en correspondance (S2) du contexte de sécurité 5G/NGS avec un contexte de sécurité 4G/EPS.
