Abstract
In a wireless communication system, a source access node receives a security policy for a User Equipment (UE) from a wireless network core. The wireless network core and the UE establish security context over the source access node. The wireless network core and the UE exchange user data over the source access node based on the security context. The source access node handsover the wireless UE to a target access node and transfers the security policy for the wireless UE to the target access node. The target access node signals the wireless network core to establish new security context for the wireless UE responsive to the security policy. The wireless network core and the wireless UE establish new security context over the target access node. The wireless network core and the UE exchange additional user data over the target access node based on the new security context.
