S6b Interface
This reference point, between a P-GW and a 3GPP AAA server/proxy, is used for mobility-related authentication. It
may also be used to retrieve and request parameters related to mobility and to retrieve static QoS profiles for UEs (for
non-3GPP access) in the event that dynamic PCC is not supported.
