Abstract
The present disclosure relates to a technique for maintaining communication established between a mobile node (20) and a home network (100) of the mobile node (20). A method embodiment comprises the step of: determining whether the mobile node 20 has moved to a foreign network (120) different from the home network (100); wherein, when it is determined in the step of determining that the mobile node (20) has moved to the foreign network (120), the method embodiment further comprises the steps of: signalling, by the mobile node (20), a foreign address assigned by the foreign network (120), to a home agent (10) of the home network (100); and maintaining the communication between the mobile node (20) and the home network (100) by establishing communication between the mobile node (20) and the home agent (10) of the home network (10) for transmission of Data Link Layer (“DLL”) frames through an Internet Protocol (“IP”) based network (140), wherein the mobile node (20) is addressed by the home agent (10) by means of the foreign address assigned by the foreign network (120).
