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.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
-
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
-
For a specific reference, subsequent revisions do not apply.
-
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
