▀ eHRPD Network Summary

Evolved Packet Control Function (ePCF)

The ePCF is an entity in the radio access network that manages the relay of packets between the eAN and the HSGW.

The ePCF supports operations for the EPS – eHRPD RAN in addition to legacy packet control functions.

The ePCF supports the following:

Main service connection over SO59

Signaling over Main A10

HRPD Serving Gateway (HSGW)

The HSGW is the entity that terminates the HRPD access network interface from the eAN/PCF. The HSGW

functionality provides interworking of the AT with the 3GPP EPS architecture and protocols specified in 23.402

(mobility, policy control (PCC), and roaming). The HSGW supports efficient (seamless) inter-technology mobility

between LTE and HRPD with the following requirements:

Sub 300ms bearer interruption

Inter-technology handoff between 3GPP E-UTRAN and HRPD

Intra-technology handoff between an HSGW and an existing PDSN

Support for inter-HSGW fast handoff via PMIPv6 Binding Update
