Abstract: Providing connections to terminals in an access node of a first network. A message is received in the access node from a terminal, the message including capability information of the terminal. The terminal is identified in the access node on the basis of the received capability information as an intermediary node capable of relaying traffic between the first network and a second network. Parameters for a connection between the access node and the terminal are determined in the access node on the basis of the identification of the terminal as intermediary node and used in establishing the connection between the access node and the terminal.

Abstract: The present invention presents a method and a controller for selecting the type of connection used to connect a terminal device to a serving base station. The connection type is selected on the basis of monitored communication-environmental parameters of the terminal device. The selection is made between a direct cellular radio connection and a relayed cellular radio connection. The relayed connection is established through another terminal device acting as a relay terminal for the connection being relayed. A direct device-to-device link between the two terminal devices is established as a cognitive radio connection, and a radio access technology and communication parameters of the device-to-device link may be negotiated between the terminal devices. The relay terminal then links the device-to-device link to a direct cellular radio connection between the relay terminal and the serving base station.

Abstract: The generation of charging data and charging traffic is reduced during idle periods of an always-on connection. During the detection of idle periods on the always-on connection special data like ICMP messages, keep alive messages and polling messages is ignored and not counted as active traffic. When an idle period is detected the charging session related to the always-on connection is suspended for the duration of the idle period in order to reduce the generation of charging data related to the idle always-on connection without terminating the charging session. Further on the user is not billed for the detected periods where the always-on connection was idle.
