** Chained S2a/S2b and S8 used when VPLMN has business relationship with Non-3GPP Networks and S-GW in VPLMN includes local non-3GPP Anchor.

The following are some additional considerations in this case:

Gxc is used only in the case of PMIP-based S8 and for 3GPP access.

NOTE 3:
If QoS enforcement on PMIP-based S8 is required by the Serving Gateway for Un-trusted Non-3GPP IP Accesses, static policies will be used in this Release of the specification.
Gxc is not required for Trusted Non-3GPP IP Access; Gxa is used instead to signal the QoS policy and event reporting.

NOTE 4:
For S2a using a Trusted WLAN access, refer to clause 16.
