Abstract: A system and method for configuring a Traffic Flow Template, TFT, in real time. The present invention dynamically adapts the TFT to control the routing of downlink data packets from a GGSN to an MS. When the MS sends an uplink data packet on a premium bearer channel, a TFT controller extracts from the uplink data packet, parameters which include at least the destination address of the uplink data packet. A downlink packet filter subset for filtering downlink data packets is then defined as a function of the extracted parameters. For example, the downlink packet filter subset may identify downlink data packets having a source address that matches the destination address of the uplink data packet. The TFT is then modified as a function of the downlink packet filter subset to route the identified downlink packets through the premium bearer channel to the MS, and to route differently, downlink data packets having source addresses that do not match the destination address of the uplink data packet.

Abstract: The present invention relates to an arrangement comprising a functional server node forming part of a conglomerate, or pool, of functional server nodes in common controlling a number of radio network control means, each functional server node being able to control any, or a number of, radio network control means, to which mobile stations are connected. The functional server nodes support transfer/redistribution of mobile stations between each other without interrupting the connection of the mobile stations, a target functional server node, to which it has been decided that a mobile station is to be transferred from a current functional server node, generates an area update or transfer acceptance message comprising an identification of the current functional server node, an identification of the target functional server node and a transfer indications. The invention also relates to a method of redistributing or transferring mobile station contexts.

Abstract: A friction stir welding method and a structural body formed using a friction stir welding method. In particular, a friction stir welding method and a structural body made of an aluminium alloy extruded frame member formed by friction stir welding of a number of extruded frame members. Joining is performed by abutting a first member with a second member by contacting a downwards facing surface of an overlapping portion of a first member which projects above one face of the other member in the lateral direction in and an upwards facing surface of a second member in such manner that the downwards facing surface and the upwards facing surface are in slideable contact before joining and the first and second member are rotatable, and carrying out a friction stir welding to join the members to form a frame structure.

Abstract: A packet radio data network includes a gateway node (GGSN), at least one serving node (SGSN) coupled to the gateway node, a plurality of radio access nodes (RAN) coupled to the serving node (SGSN), the packet radio network transporting packet data from an external packet data network. The external packet data network includes, an Internet Service Provider (ISP), to mobile stations (MS) wirelessly attached to radio access nodes (RAN). A mobile station (MS) issues a membership report message requesting content of a specific multicast group, whereupon the gateway node (GGSN) issues a multicast context activation message to the serving node (SGSN). The serving node (SGSN) informs the radio access network (RAN) that the mobile station is joining the respective multicast group and sends a multicast activation response to the gateway node (GGSN).

Abstract: A gas liquid contact body for use in a gas liquid contact apparatus is disclosed which consists of at least first and second sets of corrugated sheets with the sheets in the first set being disposed alternately with the sheets of the second set. The corrugations in the first set of sheets extend vertically in the contact body and the corrugations in the second set extend at an angle to the corrugations of the first set. The passageways formed between the inclined corrugations and the vertical corrugations serve to distribute air and water evenly through the contact body and avoid clogging thereof.
