Abstract  Abstract

A method of and apparatus for handover between a 3GPP based network and a non-3GPP network is disclosed where a policy update to a new gateway is requested. A confirmation of the policy update is sent from the policy and charging rules function (PCRF) to the 3GPP packet data network gateway (PDN GW). The new gateway also confirms the policy update to the currently serving gateway. The tunnel endpoints and radio resources are released between the PDN GW and the evolved Packet Data Gateway (ePDG) thereby freeing the resources previously used by the wireless transmit/receive unit (WTRU). A release acknowledgement is sent from the serving gateway to the PCRF confirming the policy update process is complete. The method may be used for handover between 3GPP and non-3GPP networks and vice versa. The method and apparatus may be practiced over the S2b or S2c interfaces.
