Abstract
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.
