METHOD AND APPARATUS FOR ESTABLISHING AND USING PDN CONNECTIONS

摘要

A method is described of establishing and/or using a plurality of packet data network connections between a user equipment (2) and a 3GPP core network (4) via a gateway node (12) in a non 3GPP access network(6) comprising using a different device identifier for each packet data network connection of the plurality or at least for each packet data network connection of the plurality that is associated with the same IP address to distinguish between the packet data network connections of the plurality or to allow such a distinction to be made wherein the device identifier used to distinguish between the packet data network connections of the plurality is a device identifier associated with the user equipment (2) or a device identifier associated with the gateway node (12) in the non 3GPP access network(6) or a combination of these. The device identifier may be a MAC address.
