摘要:
A communication system having a conference server device, a conference control unit, a plurality of moderator units, and a plurality of telecommunication devices. The moderator units are used to control allocation of a communication right. The decisions of the moderator units regarding the allocation of the communication right are combined to form an unambiguous overall decision, and overall decision is made using a majority decision.
摘要:
A method is provided for the administration of a muticast service whereby mobile terminals of users who have subscribed to the multicast service receive multicast messages via a mobile communication network. The present invention seeks to use the available radio resources in a more economical manner. To this end, the mobile terminals are respectively prodied with an input unit which, when actuated, produces activation information which indicates whether the multicast service is activated or deactivated, and the activation information is transmitted to the mobile communication network.
摘要:
Communications system having first, second, and third communications networks, a subscriber device, and a network access device having a network layer address. The network access device permits access by the first communications network to the third communications network and access by the second communications network to the third communications network. There is a communications link between the subscriber device and the third communications network via the first communications network and the network access device, wherein the network layer address is used during the transmission of data via the first communications link. The network access device has a control device that releases the first communications link and sets up a second communications link between the subscriber device and the third communications network via the second communications network and the network access device. The network layer address of the network access device is used during the transmission of data via the second communications link.

摘要:
A system and method for managing the communication rights of communication media groups such as audio, video, and text data streams, as well as the communication rights of a plurality of telecommunication devices participating in a telecommunication conference is provided. The communication rights of the telecommunication devices are managed in the course of the telecommunication conference taking into account the communication media group, using a control communication protocol for controlling a real-time data transmission communication protocol.
摘要:
A method of transmitting data from a sender to a number of recipients in a system with a multilayer protocol architecture, in which the data are divided for organizational purposes into data packets having header data and payload data, a transmitting and/or receiving unit and a communication system. The transmission of data in the form of a point-to-multipoint transmission over a general channel, in particular in a mobile radio system, is carried out by adding to packet data which are being sent to multicast groups control data for the identification of a specific multicast group.
摘要:
In a method for adapting uplink signaling during multicasting, the user devices of a multicast group receive a multicast message from a network control unit via a radio channel (PMcCH) in a downlink connection. The radio channel is adapted with respect to its power by transmitting information in an uplink connection via a corresponding radio channel (UL-DPCCH). The radio channel (UL-DPCCH) is power-controlled via at least one associated common radio channel (DL-PMcCH) that is associated with one or more of the user devices by transmitting corresponding information in the downlink direction from the network control unit to the user devices. The information is then processed by the receiving user devices to adapt the power of the respective associated radio channels (UL-DPCCH) in the uplink direction.
摘要:
A communication link from a first telecommunication device to a second telecommunication device is established via a telecommunication network. Several multimedia objects of a telecommunication user are stored in the second telecommunication device along with a reference number. An allocation map is defined which indicates allocation of a specific call receiver to a specific reference number of a multimedia object. A request is then sent from the first telecommunication device associated with the first telecommunication user to the telecommunication network, the request indicating that a communication link should be established from the first telecommunication device to the second telecommunication device allocated to a selected call receiver. The reference number that is designated to the selected call receiver is determined based on the allocation map, and a call signal is transmitted to the second telecommunication device together with a displayed piece of information in accordance with the determined reference number, whereupon a multimedia object is reproduced by the second telecommunication device according to the displayed piece of information.
摘要:
A message generating arrangement determines whether a first communication terminal of a communication system can participate, by means of packet-switching network elements of the communication system, in a communication link in which a second communication terminal of the communication system is participating by means of circuit-switching network elements of the communication system, and generates a message on the basis of the result of the determination.
