7 Security procedures between UE and EPS access network elements
7.2 Handling of user-related keys in E-UTRAN
7.2.7 Key handling for the TAU procedure when registered in E-UTRAN
If the "active flag" is set in the TAU request message or
the MME chooses to establish radio bearers when there is pending downlink
UP data or pending downlink signalling, radio bearers will be established
as part of the TAU procedure and a KeNB derivation is necessary.

5.4.4.1:
"When the AMF receives Registration Request with the Registration type set
to Initial Registration or when it receives the first Registration Request
after E-UTRA/EPC Attach with Registration type set to Mobility Registration
Update, the AMF deletes the UE radio capability."
o TS24.301(4G/LTE)
5.5.1 Attach procedure
5.5.1.2 Attach procedure for EPS services
5.5.1.2.4 Attach accepted by the network
If the attach request is accepted by the network,
the MME shall delete the stored UE radio capability information
or the UE radio capability ID, if any.
o TS24.501(5G)
5.5.2 De-registration procedure
5.5.2.1 General
When the AMF enters the state 5GMM-DEREGISTERED for 3GPP access,
the AMF shall delete the stored UE radio capability information
or the UE radio capability ID, if any.
