The method comprises receiving at the non-3GPP access network a request to establish the PDN connection; communicating with the 3GPP core network to establish a tunnel for the PDN connection between the non-3GPP access network and the 3GPP core network and to assign an IP address for the tunnel, which tunnel IP address is used subsequently by the non-3GPP access network to distinguish between the new PDN connection tunnel and at least one other such PDN connection tunnel already established for the UE, wherein the 3GPP core network is responsible for assigning the IP address, and sending address information from the non-3GPP access network to the 3GPP core network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for establishing a PDN connection","description":"A method for use in establishing a packet data network, PDN, connection from a user equipment or UE, to a 3GPP core network via a non-3GPP access network.
