as of September 28, 2012
This section
provides information on SAEGW feature changes in Release 14.0.
IMPORTANT:
For more information
regarding features in this section, refer to the System Architecture
Evolution Gateway Administration Guide for this release.
New SAEGW Features
This section
identifies new SAEGW features available in Release 14.0.
Added Support for
IPSec “Ping”
Added a lookup routine
to check if address pool has IPSec tunnel flow IDs. If so, the system uses
the longest prefix match to find the correct tunnel and forward
the reply to the source using the tunnel.
Modified SAEGW Features
This section
identifies SAEGW features modified in Release 14.0. There are two
kinds of modified features: enhancements and behavior changes. Enhancements
are feature changes based on customer change requests. Behavior
changes are feature changes that modify an existing behavior and
may result from software error corrections (bug fixes).

New SAEGW Features
This section
identifies new SAEGW features available in Release 14.0.
Optimized SAEGW
The SAEGW node is a
combination of S-GW and P-GW nodes. SAEGW operates as a service
on ASR5x00 and requires existing S-GW and P-GW services to be configured
and mentioned inside SAEGW service configuration. Existing standalone
S-GW and P-GW services (when part of an SAEGW umbrella service)
will work in tandem to present a single SAEGW node as a black-box
view.
The SAEGW supports all
of the interfaces that the standalone S-GW and P-GW products support,
namely:
- S11/S4 – GTPv2
based control interface towards MME/S4-SGSN
- S1U/S12/S4U – GTPv1
based data interface towards eNodeB/RNC/S4-SGSN
- S5/S8 – GTPv2
based control interface between S-GW and P-GW
- Gi – Data interface
towards packet data network
- Gx – Diameter
based interface between P-GW and PCRF
- S6b – Diameter
based interface between P-GW and HSS
- Rf – Diameter
based offline charging interface between P-GW/S-GW and
charging data function
- Gy – GTPP based
online charging interface between P-GW and online charging system
- Gz – GTPP based
offline charging interface between P-GW/S-GW and charging gateway
function
Mode of operation is
described as the functionality performed by SAEGW for a call. Granularity
for mode of operation is per-PDN. The SAEGW service supports the
following three modes of operation:
- S+P Collapsed:
When a UE is using S-GW part of SAEGW and a PDN connection is terminating
within the P-GW part of SAEGW.
- Pure-S: When a UE is
using S-GW part of SAEGW and a PDN connection is terminating at
an external P-GW not part of SAEGW.
- Pure-P: When a UE is
using an external S-GW not part of SAEGW and a PDN connection is
terminating within P-GW part of SAEGW.
IMPORTANT:
For a given UE with
multiple PDNs, SAEGW will be able to support S+P mode for
some PDNs while Pure-S mode for others.
IMPORTANT:
SAEGW supports change
of operation-mode in life of a PDN. For example, a PDN initially doing
S+P mode may change to doing Pure-P if S-GW gets relocated
to external S-GW that is not part of SAEGW. Similarly, a PDN doing
Pure-P mode may change to S+P mode if S-GW relocated so
that new S-GW is part of SAEGW service.
An optimized SAEGW provides
the following benefits:
- Higher CapacityA UE with one PDN connection
that passes through standalone S-GW and P-GW services consumes two
license units because both S-GW and P-GW services account for it
separately. SAEGW as a single node consumes only one license unit
for the same, thus increasing the capacity. Contact your Cisco account
representative for detailed information on product licensing.
- Cohesive ConfigurationConfiguration and management
of SAEGW as a node is easier to follow than starting standalone
S-GW and P-GW services.
Modified SAEGW Features
This section
identifies SAEGW features modified in Release 14.0. There are two
kinds of modified features: enhancements and behavior changes. Enhancements
are feature changes based on customer change requests. Behavior
changes are feature changes that modify an existing behavior and
may result from software error corrections (bug fixes).
