Feature Changes
External Messaging Behavior Change
Previous Behavior: When a subscriber comes to the MME from SGSN, the MME was always sending 4G Native QOS

of a subsequent handoff to GN/GP SGSN.

of a subsequent handoff to GN/GP SGSN.
New Behavior: A new command is provided which controls which QOS the MME uses in NAS GMM QOS IE and
GTPV1 Context response messages during a handover or inter-rat TAU with a GN/GP SGSN.
GTPV1 Context response messages during a handover or inter-rat TAU with a GN/GP SGSN.
The MME can either send the QOS sent from peer SGSN, or the native EPS (4G) QOS value received from HSS. The
default behavior is to send the native EPS (4G) QOS to the SGSN.
