A method of conveying data unit traffic from a radio terminal in a mobile communication system that comprises an access network (E-UTRAN) and a core network (Evolved Packet Core) is described. It comprises:&#x2014;receiving (S31) a service request message for data unit communication from said radio terminal, and&#x2014;performing (S32) a conveying decision procedure, and on the basis of an outcome of said conveying decision procedure, associating a radio channel between an access network entity and a radio terminal with one of &#x2014;a channel to a dedicated data unit processing entity (P-GW) in said core network for conveying data units from said radio terminal to said dedicated data unit processing entity for processing (S33), and&#x2014;an access network channel for conveying data units from said radio terminal within said access network (S34).

Method and entity for conveying data units

This proxy for at least one end-to-end data flow in a network comprises an estimation unit, for estimating the current minimum data load necessary to occupy the bandwidth available to the flow in the network. The estimation unit outputs a flow's pipe capacity estimation. This proxy also comprises a comparison unit, for comparing the estimated pipe capacity with a predetermined capacity threshold, a decision unit, for deciding to proxy the end-to-end flow if the estimated pipe capacity lies above the capacity threshold, and a routing unit, for routing the flow according to the decision.

Method and devices for adaptive proxying of flows

Method for secure user access to a remote system using a communications device. Access to the system is released only after the input of valid code words via independent communications devices. One of the communications devices may be a data processing unit and the second communications device may be a mobile telephone.

Method for securing access to a remote system

A method, and associated apparatus, formats asynchronous data, such as ATM data traffic, and synchronous data, such as synchronous voice traffic, pursuant to a common format. Once formatted pursuant to the common format, data generated during operation of two different types of communication systems can be communicated over a common radio link. A single frequency band can be used to communicate communication signals generated during operation of at least two separate communication systems.
