Abstract: A method of supporting access to a selected Internet Protocol (IP) multimedia application via an IP Multimedia Subsystem (IMS) is provided for a roaming mobile node (MN)—i.e., user equipment (UE)served by a wireless telecommunications system. The method includes: includes establishing a first IP tunnel between the UE and a local access gateway of a visited network, the first tunnel being anchored at the local access gateway; establishing a second IP tunnel between the UE and a home gateway of a home network, the second tunnel being anchored at the home gateway; receiving data packets at the local access gateway for the UE; filtering the packets received at the local access gateway to suitably classify corresponding traffic into one of a plurality of data flows supported within the first tunnel at varying Quality of Service (QoS) levels; and filtering the received packets.

Abstract: A method is provided for administering an interactive real world game in which a player (20) is to find a designated target. Suitably, the player (20) employs mobile user equipment (UE) (40) to participate in the game, wherein the UE (40) is served by a wireless access network (32) providing the UE (40) access to an Internet Protocol (IP) Multimedia Subsystem (IMS) (30). The method includes: sending a clue to the UE (40) via the IMS (30), the clue hinting at an identity of the designated target; receiving an answer to the clue, the answer being submitted from the UE (40) via the IMS (30); and, determining whether the received answer correctly or incorrectly identifies the designated target.

Abstract: A method of supporting access to a selected Internet Protocol (IP) multimedia application via an IP Multimedia Subsystem (IMS) is provided for a roaming mobile node (MN)—i.e., user equipment (UE) (10)—served by a wireless telecommunications system. The method includes: establishing a first IP tunnel (20) between the UE (10) and a local access gateway (30) of a visited network in which the UE (10) is roaming, the first tunnel (20) being anchored at the local access gateway (30); establishing a second IP tunnel (22?) between the UE (10) and a home gateway (40?) of a home network to which the UE (10) belongs, the second tunnel (22?) being anchored at the home gateway (40?); receiving data packets at the local access gateway (30) for the UE (10); filtering the packets received at the local access gateway (30) to suitably classify corresponding traffic into one of a plurality of data flows (20a, 20b, . . .
