Abstract: According to an aspect of this disclosure, a communication device is provided comprising a first interface configured to receive a first packet supplied by a packet encoder; a determiner configured to determine a time difference between the time at which the first packet is ready to be sent by the communication device and a time at which communication resources for sending the first packet are available; a generator configured to generate information from which it is derivable when a second packet should be provided by the packet encoder based on the time difference; and a second interface configured to transmit the information to the packet encoder.

Abstract: A method for communication setup including transmitting a first message including an indication of a list with a plurality of list elements, wherein each list element specifies a communication service or a communication application computer program; receiving the first message; selecting at least one of the list elements; and transmitting a second message comprising an indication specifying which list element has been selected.

Abstract: A method for group communication between subscribers to different messaging services involves a first message, which has been sent by a second subscriber using a first messaging service, being received by a communication terminal of a first subscriber in a group communication session in which said communication terminal, the second subscriber and a third subscriber are participating. The communication terminal is used in the group communication session to send a second message, which contains a content from the received first message, to the third subscriber for reception using a second messaging service, which is different than the first messaging service.

Abstract: The invention relates to a radio device and method for transmitting radio signals including an electrical interface having at least one data terminal for connecting the radio device to an external data source, and comprising a transmitting device which is in communication with the at least one data terminal and which generates the radio signals with data signals of the external data source, transmitted via the at least one data terminal. The radio device exhibits an energy extraction device, the input of which is connected to the at least one data terminal and the output of which is connected to a power supply input of the transmitting device and which takes energy from the data signals of the external data source and feeds this energy at the power supply input into the transmitting device in order to operate it.
