About the eHRPD Application


The High Rate Packet Data (HRPD) is a packet data protocol in the 3G mobile communications network based on CDMA2000. Evolved HRPD (eHRPD) is a method that allows the mobile operator to upgrade their existing HRPD packet core network using elements of the SAE/EPC architecture. Additionally, eHRPD is a more evolutionary path to LTE while also allowing for seamless service mobility  — including seamless hand-offs — between the eHRPD and LTE networks.

The diagram below shows the eHRPD core network components for the interworking between E-UTRAN and eHRPD with the following reference points:

The H2 reference point carries user traffic between a source HSGW (S-HSGW) and a target HSGW (T-HSGW) for optimized inter-HSGW handoff.
