The document provides an overview of Cisco's mobile offload architecture and frameworks. It discusses the market environment driving increased mobile data usage and the need for offloading traffic from cellular networks. The presentation then describes Cisco's SP WiFi offload architecture, which features intelligent radios, a unified architecture, seamless user experience, and converged core to enable scalable carrier-grade offload of mobile data traffic onto wireless networks.

14. Access Offload
• Principle
–Divert UE access traffic to an unlicensed (e.g. WiFi) or licensed (e.g. 3G
Femto) access every time possible.
• Benefits
–Save precious macro radio capacity
–Address in-building coverage and capacity issue
–Save backhaul costs by using broadband transportt
• Drawbacks
–QoS Guarantee (esp. when using unlicensed spectrum)
–Client requirement for some archicture
–Complex architecture requiring a new CPE and end-to-end provisioning
(esp. Femto)
Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 21

15. Access Offload Alternatives
• Unlicenced Spectrum – WiFi
• Several options depending on the following points
• Client
•Clientless (manual selection, web auth or auto selection WISPr/HotSpot2.0)
•Client-enabled (Connection manager for network selection and optionally
network auth (EAP-SIM/AKA, etc.)
• Traffic Handling
•Direct Offload (i.e. no operator control)
•Traffic Control on a dedicated network element
•Aggregation at the mobile packet core (on a PDG per I-WLAN spec)
• Mobility
•Session mobility
•Inter-AP mobility (likely to become an issue in dense WiFi areas such as
hotzones/enterprise and also Community WiFi) – Covered later in this preso
• Licenced Spectrum – 3G
• Consumer/Enterprise Femtocell
• Enterprise Picocell
Not covered in this preso
• Hotzone Picocells
