Abstract
A method is provided for interworking of mobility key management among access networks operating under different access technologies. The method is carried out by performing mobility key management by a core-network authentication server based on the access technology that a mobile terminal accessing a wireless network has selected for operation. The method of the invention defines authentication server behavior based on different access technologies and therefore solves the technology interworking issue seamlessly. The method of the invention also facilitates coexistence of more than two different access technologies without any need for each access technology to be modified in order to interwork with core network that is specified by another technology.
