New GGSN Features
This section identifies GGSN features and functionality added in release 15.0.
3GPP TS 29.281 (GTPU) Release 10 Compliance
The GGSN now complies to 3GPP TS 29.281 Rel-10. Support for UDP Port Extension header in Error indication
message and Supported Extension Headers Notification message was added to become fully compliant with 3GPP
Release 10.
message and Supported Extension Headers Notification message was added to become fully compliant with 3GPP
Release 10.
Supported Extension Headers Notification message indicates a list of supported Extension Headers that the node can
support. This message is sent only in case a GTP entity was required to interpret a mandatory Extension Header (by
setting the comprehension required in extension header) but the GTP entity was not yet upgraded to support that
extension header.
support. This message is sent only in case a GTP entity was required to interpret a mandatory Extension Header (by
setting the comprehension required in extension header) but the GTP entity was not yet upgraded to support that
extension header.
If a Supported Extension Headers Notification is received from peer GTPU entity, node will not send the
Extension Header to the peer entity.
If a message which contains Extension Header is received from peer GTPU entity; if the extension header is set
to comprehension required and the extension header cannot be interpreted by the node, it will send a Supported
Extension Headers Notification message. This message shall include all the extension headers supported by the
node.
Extension Headers Notification message. This message shall include all the extension headers supported by the
node.
UDP Port Extension header helps in handling the Error-Indication message efficiently. If any GTPU peer supports this
extension header, then sending this extension header in Error-Indication message will help in processing the Error-
Indication message.
extension header, then sending this extension header in Error-Indication message will help in processing the Error-
Indication message.
With the support for Supported Extension Headers Notification message it helps notifying the GTPU peer about the
GTPU capabilities of the node. This message is sent only in case the node was required to interpret a mandatory
Extension Header (by setting the comprehension required in extension header) but the node was not yet upgraded to
support that extension header.
GTPU capabilities of the node. This message is sent only in case the node was required to interpret a mandatory
Extension Header (by setting the comprehension required in extension header) but the node was not yet upgraded to
support that extension header.
DSCP Marking - GTP-U on per APN Basis
Previous Behavior: Prior to release 15.0, DSCP marking table was configured on GGSN service level.
New Behavior: From release 15.0 onward, CLI is added to associate the qos-qci-mapping table in APN.
This feature provides the flexibility to have a different DSCP marking table on per APN basis so that traffic on each of
the APNs can be marked differently, depending on the needs of the APN.
