6.11 S2c Bootstrapping via DSMIPv6 Home Link over a Trusted Access

23.4023GPPArchitecture enhancements for non-3GPP accessesRelease 18TS

When the UE is connected on a trusted non-3GPP access considered to be DSMIPv6 home link for the UE based on clause 4.5.6, the UE may trigger the establishment of S2c IKEv2 SA, e.g. to optimize future handovers to other accesses using S2c. For each PDN connection, the S2c IKEv2 SA establishment has to be performed separately.

NOTE: A trusted non-3GPP access can be defined as DSMIPv6 Home Link in addition to the 3GPP access.

Once the UE is attached to the PDN over the trusted non-3GPP access, the procedure describing the bootstrapping is in clause 15.1.
