摘要
A method, apparatus and computer program product are provided to provide fresh security context during intersystem mobility. A method is provided which includes receiving an indication of handover of a remote device from a source system to a target system. The target system may implement a communications standard different from that of the source system. The method also includes determining a current sequence number value of a security context maintained in the source system. The method additionally includes deriving a fresh mapped security context for the target system based at least in part upon the determined sequence number value. The method further includes providing the derived fresh mapped security context to the target system.
