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:
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.

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.

A method is provided for the transmission of at least one group message to at least one group of one or more radio communication devices in at least one radio cell of a radio communication network, working in particular on the UMTS standard, using at least one linked set of data, transmitted during at least one time interval from at least one transport channel, in particular embodied as a DSCH channel, to a multiplex channel, in particular embodied as a CCTrCH, whereby permitted data sets are determined with a flag, identifiable by a first indicator, whereby the first indicator is allocated to the group during the time interval. The present invention further provides for a network control unit and a radio communication device with the capacity to carry out the method.

摘要:
A method determines the local position of at least one mobile radio communication device which is to be locates, in at least one radio cell of a radio communication system. At least one remote mobile radio communication device is located in the same radio cell or in another radio cell as the radio communication device which is to be located, and the current local position thereof is predetermined to said device or to the radio network of the radio communication system and transmits positional information by one or several radio information signals via a direct radio connection or via an indirect radio communication device with the aid of the radio network to the radio communication device which is to be located.
摘要:
A transmission channel, for the transmission of messages from a mobile terminal to a base station, is selected after a terminal sends a send authorization request signal, for a particular transmission channel, to the base station and the base station sends a reply signal with a first decision value. The terminal is thus signaled whether the terminal is authorized to send a message on the requested transmission channel. On sending a first negative decision value, the base station sends a second positive decision value with the reply signal, when the terminal is authorized to send a message on another transmission channel. On detection of a first negative decision value, the terminal analyzes the reply signal further for whether a second positive decision value is contained therein and which other transmission channels are available and hence sends the message on one of the available transmission channels.

In the course of a half-duplex telecommunication session, a message has a message validity information item added to it and, if appropriate, a check is performed to determine whether or not the message is valid.
摘要:
A telecommunication system, method, and terminal, the terminal having a telecommunication session message generation unit adding to at least one generated telecommunication session message a message validity information item indicating whether or until when the telecommunication session message or another telecommunication session message identified in the telecommunication session message is valid.
