摘要： The conference device (EMCU) according to the invention has several monaural HRTF filters (HRTF1, . . . , HRTFN), each of which is to be allocated to a conference participant. The abbreviation HRTF stands for “Head Related Transfer Function”. A corresponding HRTF filter (HRTF1, . . . , HRTFN) is used for filtering a monaural audio signal coming from the conference participant to whom it is allocated. An individual, monaural HRTF filter coefficient set is responsible in this case for defining the filter characteristics of a particular HRTF filter. The conference device (EMCU) also has a conference mixing device (MP) coupled to the HRTF filters (HRTF1, . . . , HRTFN), for mixing the individually filtered audio signals from various conference participants and for transferring the mixed audio signals to conference participants.

摘要： The invention relates to a method and a device for which, for determining a routing-metric for a mesh-network, in particular according to standard IEEE 802.11s, routing messages sent in wireless mesh networks or mobile ad-hoc-networks, on various paths of source nodes, via the mesh nodes of the mesh networks to the target nodes, are evaluated in order to determine the best path for transferring data packets from source nodes to target nodes. Said nodes are battery-operated and mesh nodes are only used in the energy-saving mode as intermediate nodes of a path when this can not be prevented due to necessary connectivity in the mesh network or due to predetermined guidelines. Also, in each routing message sent from source nodes to target nodes via various paths, a plurality of bits, preferably two bits, are used for the number of mesh nodes operating in the path in the energy-saving mode or are battery-operated when the remaining bits of the routing-message are used for the path metric.

摘要： A method and apparatus for transmitting a notification of a shutdown event includes a communication terminal turning off or otherwise shutting down and prior to turning off sending a notification to a third party device such as an access point, base station, server, or proxy, that identifies information relating to the shutting down of the terminal such as a location, purpose for the shutdown and other relevant information. Subsequent devices that attempt to establish a communication connection with the terminal may then receive the notification or information from the notification via the third party device. The sending of information relating to the notification or the notification by the third party can also trigger another action. One example of such an action is the forwarding of the communication connection request to another device to receive that request based upon a predefined rule or a predefined forwarding address.

摘要： The invention relates to a method for operating a mesh network, especially according to IEEE standard 802.11s, wherein the mesh network comprises a plurality of network nodes, which have outer edge nodes and inner network nodes. A first edge node forms a connection point for external first stations disjunctive to the network, and a second edge node forms a connection point for external second stations disjunctive to the network, wherein data packets are to be exchanged between the first and second stations. During a switch of an external station from one edge node to another edge node, especially from a coverage area of the first edge node to a coverage area of the second network node, the respective association information of the network nodes is updated by means of an association message while inserting a validity duration for the association of the external stations connected to the edge nodes. The invention also relates to a device for carrying out the method for operating a mesh network.

摘要： One network protocol (RTP) each, having data packets (dp) comprising an expandable header (KE) is provided for a data stream (ds1 . . . n) encoded in a manner individual to said data stream, and the key information (si1 . . . n) formed in a data stream manner individual to said data stream is inserted into an expandable header (RTPH) of a data packet (dp) of the respective data stream (ds1 . . . n) and transmitted. The key information (sp1 . . . n) is selected in a manner individual to said data stream from the expanded headers (KE) of received data packets (dp) of the respective data stream (ds1 . . . n), and the associated encoded data stream (ds1 . . . n) is decoded by means of at least one piece of selected data stream individual key information (si1 . . . n). The forming and inserting of key information (si1 . . . n) into standard expanded headers (KE) can be performed with little additional expense, thus significantly reducing the expenditure for the analysis or diagnosis of the simultaneously transmitted encoded data streams (ds1 . . . n). Advantageously, the insertion of key information (si1 . . . n) can be activated or initiated only if the diagnosis or analysis and/or the recording of the data streams is currently being performed.
