Abstract
A method and apparatus for handover between a 3GPP based network and a non-3GPP network when a policy update is required for a new gateway is disclosed. Confirmation of the policy update is sent from the policy and charging rule function (PCRF) to the 3GPP Packet Data Network Gateway (PDN GW). The new gateway also checks for policy updates to the 3GPP serving gateway. Tunnel endpoints and radio resources are released between the PDN GW and the evolved packet data gateway (ePDG), thereby releasing resources previously used by the wireless transmit / receive unit (WTRU). A release acknowledgment is sent from the serving gateway to the PCRF, confirming that the policy update process is complete. The method can be used for handovers between 3GPP networks and non-3GPP networks or vice versa. The method and apparatus may be implemented via an S2b or S2c interface.
