摘要
A method and apparatus for performing a handover of a communication session from a non-3GPP access network to a 3GPP access network in which only a Gn/Gp-based Serving GPRS Support Node has been deployed in the 3GPP access network. The method includes establishing the communication session between a user equipment and an Evolved Packet Core through the non-3GPP access network, and performing a handover of the communication session from the non-3GPP access network to the 3GPP access network. Performing the handover includes providing information to the UE of a selected packet data network gateway prior to performing the handover, and providing the information of the selected packet data network gateway from the user equipment to the 3GPP access network during the handover to maintain continuity of the communication session between the user equipment and the Evolved Packet Core.
