Security for mobility over non-3GPP access to avoid full primary authentication
The following objectives are studied in the present document:
- Study the security aspects and procedure enhancements needed to support UE connecting to a new target TNAP within the same TNGF without performing full primary authentication.
- Study the security aspects and procedure enhancements needed to support AUN3 connecting to a new target RG under the same WAGF without performing full primary authentication.
- Study the security aspects and procedure enhancements needed to support N5CW devices connecting to a new target Trusted WLAN AP within the same TWIF without performing full primary authentication.
- Study the security aspects and procedure enhancements needed to support UE connecting to a new WLAN AP that shares the same NSWOF without performing full authentication.
The present document does not cover actual mobility, where call/session continuity is maintained. I.e. when UE/device is moving from one AP/TNAP/TWAP to another, connectivity can break, and then UE will reconnect.
