4G MigrationOperator Requirements

• No forklift hardware upgrade required• Base capabilities are already available

– PDN GW is built on HA and GGSN functions

• Ease of migration with diverse set of protocol capabilities– GTPv0, GTPv1, GTPv2, PMIPv4, PMIPv6, MIPv4, DSMIPv6 on same node– Seamless session transition (GTP to PMIP) for inter-technology handover– RADIUS, Diameter, and GSM MAP on the same platform– IPsec capability built-in on all platforms for unsecured access

• Future-proof architecture to leverage 2G/3G capital– Turn on MME function on SGSN– Turn on HSGW function on PDSN– Turn on SGW and PGW on GGSN

9

Common IP CoreBased on 3GPP SAE

• 3GPP SAE provides unique opportunity for operators to unify network core on a common IP architecture for multiple radio access systems

• Enabling PDN GW function on – HA for 3GPP2 operators– HA for WiMAX operators– GGSN for 3GPP operators

• Unified Policy, QoS, Charging, and Security functions based on 3GPP PCC framework for multiple access technologies

• Highly scalable access-edge functions for each access technology– PDSN and HSGW for CDMA operators– ASN-GW for WiMAX operators– SGW, SGSN and MME for 3GPP operators

10

• CDMA to/from WiMAX mobility• Network-initiated mobility via Proxy MIP• No call re-registration required• Service ubiquity over multiple access

3G and WiMax InterworkingCommon IP Core and IP Edge

• Key enabler of personal broadband– Elimination of parallel networks– Single DPI and policy touch point for service consistency

• High capacity, proven platform with global deployments of Mobile IP access gateways– Reduced call hand-offs and delay

• Management efficiencies– Reuse of AAA and provisioning systems– Simplified troubleshooting
