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. The invention also relates to a method for managing log on information that is designed for the mobile communications terminal.

Mobile communications terminal for use in several wireless local networks and method for operating

A method for transmitting data in a Wireless Local Area Network (WLAN) including transmitting a WLAN message between a terminal device and an access node of the WLAN network in the Layer 2 protocol layer. An Extensible Authentication Protocol (EAP) message is transmitted in the WLAN message. The EAP message includes a Session Initiation Protocol (SIP) message having SIP authentication data.

Method for transmitting data in a WLAN network

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.

Method for transmitting data in a WLAN network using an EAP message comprising SIP authentication data

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).

The invention relates to a method for exchanging information between components in a network by means of terminals which exchange IP information packets over the network, the IP information packets being provided with IP headers having IP addresses. The components include a memory area in which unequivocal terminal identifiers are managed in relation to IP addresses, at least one part of the components in the network being MPLS-enabled and used to route information packets through the network on the basis of MPLS paths and corresponding MPLS headers.

Method and device for mapping network headers onto MPLS headers in bearer architectures

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.

Method and arrangements for router advertisement in a network with mobile anchor points

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.
