摘要：
A method is provided of enabling access for a terminal (12-1 ) to a remote network (60) via a mobile network (40). A first connectivity service function (30) is provided as part of the mobile network (40). A second connectivity service function (20) is provided as part of the remote network (60). A third connectivity service function (10) is provided associated with the terminal (12-1). The first connectivity service function (30) is adapted to cooperate in establishing a first layer 2 tunnel (25) between itself (30) and the second connectivity service function (20). The first connectivity service function (30) is also adapted to cooperate in establishing a second layer 2 tunnel (15) between itself (30) and the third connectivity service function (10). The terminal (12-1) thereby has layer 2 access into the remote network (60) through the first and second tunnels (25, 15) using the first, second and third connectivity service functions (30, 20, 10).
