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 controlling the transmission of data via data connections associated with different applications, by means of a transmission medium in a local network having at least two stations for data transmission. Different priorities and different parameters characterizing a quality of service are associated with the applications. The establishment, by a first station, of a new data connection associated with a first application is limited according to the available free channel capacity of the transmission medium and the use of the transmission medium by existing data connections having associated applications containing a priority corresponding to the first application.

Method for controlling the transmission of data

Messages exchanged between a mobile node and a home agent according to a mobile Internet protocol are authenticated using cryptographic methods applied to the messages and which have been agreed on between the mobile node and the home agent.

Method for verifying the authenticity of messages exchanged according to a mobile internet protocol

A user terminal is switched between a cellular network and a worldwide interoperability for microwave access radio network within a telecommunication system. An authentication, authorization and accounting (AAA) server which is designed for use with both of these networks is disposed in the telecommunication system in such a way that user data of the user terminal stored in the AAA server can be accessed from both of these networks, thereby advantageously ensuring uninterrupted switching between the two networks free of loss.

Telecommunication system and method for controlling switching of user terminal between two networks

A mobile communication terminal operatively coupled to at least two mobile radio communication systems in respectively associated mobile radio networks, each of which provides a user of the communication terminal with a number of services of different type. The user may thus effect efficient management of the services provided for him by virtue of the communication terminal being designed to receive and effect further processing of data records which are associated with one respective type of the services.

Mobile communication terminal for service type signaling

A method for reducing signaling overhead in a multicarrier system with dynamic bit allocation per subcarrier and a corresponding transmitter/receiver device, are provided wherein an established bit allocation table (BAT) that is provided with an index (I) is stored in a BAT storage device (LUT). In order to reduce signaling overhead, only the corresponding index (I) of an existing bit allocation table is transmitted (S).
