Abstract

The AMF re-allocation procedure for an Initiating AMF that has reroute capability via an Access Network (AN) is optimized in scenarios where a wireless device, such as a User Equipment (UE), already shares a 5G security context with-in a Last Serving AMF that is different from the Initiating AMF, and where the Initiating AMF and the Last Serving AMF can communicate with each other via an interface.
