New SAEGW Features

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.
