eHRPD Network Summary

In a High Rate Packet Data (HRPD) network, the method of mobility is performed using client-based mobile IPv6 or

Client Mobile IPv6 (CMIPv6). This involves the mobile node with an IPv6 stack maintaining a binding between its

home address and its care-of address. The mobile node must also send mobility management signaling messages to a

The primary difference in an evolved HRPD (eHRPD) network is the use of network mobility (via proxy) allowing the

network to perform mobility management, instead of the mobile node. This form of mobility is known as Proxy Mobile

IPv6 (PMIPv6).

The eHRPD network's main function is to provide interworking of the mobile node with the Evolved Packet System

(EPS). The EPS is a 3GPP Enhanced UMTS Terrestrial Radio Access Network/Evolved Packet Core (E-UTRAN/EPC).

The E-UTRAN/EPC is the core data network of the 4G System Architecture Evolution (SAE) network supporting the

Long Term Evolution Radio Access Network (LTE RAN).

The following figure shows the physical relationship of the eHRPD network with the E-UTRAN/EPC.

The primary functions of the eHRPD network are:
