How the PDN Gateway Works

This section provides information on the function of the P-GW in an EPC E-UTRAN network and presents call
procedure flows for different stages of session setup and disconnect.

The P-GW supports the following network flows:



PMIPv6 PDN Gateway CallSession Procedures in an eHRPD Network



GTP PDN Gateway CallSession Procedures in an LTE-SAE Network

PMIPv6 PDN Gateway Call/Session Procedures in an eHRPD Network

The following topics and procedure flows are included:



Initial Attach with IPv6IPv4 Access



PMIPv6 Lifetime Extension without Handover



PDN Connection Release Initiated by UE



PDN Connection Release Initiated by HSGW



PDN Connection Release Initiated by P-GW

Initial Attach with IPv6/IPv4 Access

This section describes the procedure of initial attach and session establishment for a subscriber (UE).
