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 Capacity
  A 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 Configuration
  Configuration 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).
