3GPP S6b  Application ( 16777272 )

The S6b reference point is between the PDN Gateway (PGW) and 3GPP AAA server/proxy for mobility related authentication if needed. This reference point may also be used to retrieve and request storage of mobility parameters, and may also be used to retrieve static QoS profile for a UE for non-3GPP access in case dynamic PCC is not supported.
