Study on the security of Access and Mobility Management Function (AMF) re-allocation
The present document aims at addressing the case for the indirect reroute procedure for UE registration. The intention is to enable deployment scenarios with stricter slice isolation requirements on the core network, for example where the AMFs are unable to communicate with each other.
The aim of the present document is to:
- Collect the potential requirements related to the AMF re-allocation procedure.
- Study the potential enhancements to the security mechanisms in order to fulfil the requirements for the AMF re-allocation.
