eHRPD is publicized as the intermediate technology for the migration of cdma2000 networks to LTE. Migration of 3GPP2 architecture to EUTRAN/EPC involves the overlay of the EPC elements (MME, SGW, and PDN-GW) and the potential to use the EV-DO network to deploy the EUTRAN components for seamless interworking of services between the two technologies. Upgrading to eHRPD provides a common environment for mobility for the subscribers.

Some advantages of eHRPD deployment for CDMA Carriers are –

• eHRPD enables seamless mobility and handoff between EV-DO and LTE
• Enhances traditional EV-DO (HRPD) to enable future seamless IP mobility with LTE base on 3GPP standards for Evolved Packet Core (EPC)
• eHRPD network provides an IP environment that supports attachment to multiple Packet Data Networks (PDN) and allocation of IPv4 address or IPv6 address or both addresses for each PDN via the 3GPP Evolved Packet Core (EPC)
• Moves the IP mobility anchor out of the Home Agent and into the PDN-Gateway
• The UE uses network based mobility and relies on the use of Proxy Mobile IPv6 (PMIPv6) within the network for mobility management
• Uses EAP-AKA for RAN Authentication instead of PAP/CHAP and conforms to 3GPP standards
• Enables larger IP address space for mobiles, and simplifies security

eHRPD suite offered as a part of LTE Q-GENERIC® Solution addresses this specific need.
