Abstract: Methods and apparatus for providing a centralized source of session keys to be shared by a Home Agent and a Mobile Node are disclosed. In accordance with one aspect of the invention, a Mobile Node registers with a Home Agent supporting Mobile IP by sending a registration request to the Home Agent. The Home Agent sends a request message (e.g., access-request message) to a AAA server, the request message identifying the Mobile Node. The AAA server then derives key information from a key or password associated with the Mobile Node. The AAA server then sends a reply message (e.g., access-reply message) to the Home Agent, the reply message including the key information associated with the Mobile Node, thereby enabling the Home Agent to derive a shared key to be shared between the Mobile Node and the Home Agent from the key information. The Home Agent derives a key from the key information, the key being a shared key between the Mobile Node and the Home Agent. A registration reply is then sent to the Mobile Node.

Abstract: The disclosed embodiments support mobility internal and external to enterprise networks. Service providers provide mobility by providing Home Agent functionality corresponding to each Enterprise network. In this manner, mobility may be provided to Mobile Nodes both internal and external to their enterprise networks. Moreover, data packets may be transmitted by Mobile Nodes to Correspondent Nodes, whether they are within their enterprise network, the Service Provider network, or the Internet.

Abstract: A method and/or system for receiving or accepting and processing calls within a telephone network having lines, including a voice and a data channel, for connecting a caller to subscriber groups connected to the network. A subscriber group has an assigned network identifier via which all members of the subscriber group are able to be called by a caller. The calls intended for one subscriber group are distributed via a control to the individual members of the group on the basis of specifiable criteria, data records assigned to one connection being exchanged via the data channel, and the control being carried out by a control unit which is integrated in the network and has access to complete data records. A subscriber group may have an assigned control unit which automatically decides on the connection of a call to a special member of the group.

Abstract: In casting molten metal into open recesses in moving molds for forming plate-shaped metal parts, the molds extend between and are supported on individual links of a pair of laterally spaced link chains forming a conveyor having an upper run and a lower run and trained over a pair of spaced rolls. The upper run of the conveyor in which the molten metal is poured and cooled, travels in a rectilinear horizontal path. The links are supported on hinge pins and rollers mounted on the hinge pins ride along guide rails. Each pair of adjacent molds abut at a joint located in a vertical plane which passes through the hinge pin interconnecting the links supporting the mold. Each mold plate has a transversely arranged separating edge defining a spacer between the recesses in adjacent molds. The separating edge can be located at the end of the mold or at a location intermediate its ends.
