Abstract: The invention relates to a method for transmitting data in a WLAN network (Wireless Local Area Network), whereby WLAN messages are transmitted in the Layer 2 protocol layer between a terminal and an access node of the WLAN network. EAP messages (Extensible Authentication Protocol) are transmitted in the WLAN messages, said EAP messages containing SIP messages (Session Initiation Protocol) with SIP authentication data.

Abstract: The invention relates to a mobile communications terminal for use in a plurality of wireless local networks. Said terminal comprises a log on memory, in which an access address that is designed to be used for a new log on process is stored. According to the invention, information concerning the access addresses that were received by the mobile communications terminal in previous log on operations and the network among the plurality of wireless local networks that was used, is stored in an allocation memory. The terminal is configured in such a way that when a new access request is received for a sought network among the plurality of wireless local networks, it searches for a previous access address that was allocated for the sought network and is also configured in such a way that when said previous access address for the sought network has been found, it writes the address to the log on memory and permits the log on operation.

Abstract: The invention relates to a method for transmitting data in a WLAN network (WLAN=Wireless Local Area Network) during which WLAN messages are transmitted in the L2 protocol layer between a terminal and an access node of the WLAN network, whereby the access node can be connected to one or more data networks. According to the invention, the WLAN messages contain SIP messages with SIP authentication data (SIP=Session Initiation Protocol). The SIP authentication data is extracted from WLAN messages arriving in the access node and are integrated in the form of authentication data in messages of the RADIUS protocol and/or of the diameter protocol (RADIUS=Remote Authentication Dial In User Service).

Abstract: A method is described for processing a request message sent from a mobile radio terminal to a message filter processor, in which a request message, in which one or more electronic peer-to-peer files is/are requested, is detected by the message filter processor (102,103,104. The request message is used to create a peer-to-peer request message according to a predefined peer-to-peer communication protocol. The peer-to-peer request message is sent to at least one processor (201 . . . 207) in a fixed network communication network (200), the request message being present in the form of a data packet (300), having a packet header (301) and user data (302), and detection of the request message including reading data in the packet header (301) of the request message, the data being used to identify a specific peer-to-peer application.

Abstract: Only the routers of mobile anchor points rather than all of the routers in a network, as was previously the case, have to modify the number of the mobile anchor points. The hops are calculated from the hop limit and the respective hop numbers in the respective mobile node.

Abstract: The invention relates to a method and a device for adapting label-switched paths, in particular MPLS paths, in packet-oriented networks which comprise routers. At least some of the routers exchange information with adjacent routers, by means of a protocol, about the status of the network, in particular about load shifts, availability changes and bandwidths, in order to recognise possible bottlenecks or improvements and, in the case of adjacent bottlenecks, locally altering paths which run through said bottlenecks, by means of partial replacement paths such that said bottlenecks are by-passed and in the case of adjacent improvements, the paths which run around said improvements are altered such as to retain said improvements in the path.

Abstract: A method for routing data packets in a network analyzes data packets in the network with a selected network node. The path of the data packets to a destination address is manipulated in accordance with certain requirements. Information contained in the data packets as well as further information which is available to the network node is used for a routing. The further information can either be called up from a database of the network node or from a plurality of tables, which may be distributed in the network. A transfer node, such as a switching service, which is suitable for the requirements is determined. An apparatus for routing data packets in a network is also provided.

Abstract: When mobile data transmission occurs in a data network, a modification of an IP address in a lower protocol layer which, for example, uses the DCCP protocol supporting modification of the IP address in an existing data link, is indicated in relation to a higher protocol layer such that links existing in the higher protocol layer can be updated with the IP address. The higher protocol layer can include the SIP signaling protocol during a Voice-over-IP-voice communication application, for example, in addition to a real time data transmission protocol. Said SIP signaling protocol can update URI identifier and IP address assignment information when the address is modified.

Abstract: The invention relates to a method for processing data packets in a data network which has a mobile function. A terminal and a data source use a first network protocol, according to which addresses of the first network protocol, reproduced in a first format are assigned to the terminal and the data source. A second network protocol is used in the data network, according to which addresses of a second network protocol, reproduced in a second format are assigned to computers in the data network. The terminal is assigned to a home network and receives in said network a home address of the first network protocol, reproduced in a first format. The terminal also receives a second address of the second network protocol, reproduced in a second format.

Abstract: The invention relates to a method for header compression in packet-oriented networks, comprising at least one receiver and one transmitter between which information packets are exchanged by means of MPLS headers. Said information packets are tunneled by another protocol by means of a network header. Said MPLS headers are selected, such that a clear representation of a MPLS header an the second network header is possible. Said method comprises a first initialization step, whereby the receiver stores a representation of said MPLS header on the network header. In a second step following said initialization step, the transmitter removes the network header of the second protocol from the information packet and fills in the free space, thus obtained, with other information, in order to then transmit said information packet to the receiver. Said method comprises a third step, whereby the receiver assigns the network header to the information packet, based on the stored representation.
