摘要:
A method is provided for transmitting data from a sender to a number of receivers. Also provided are an emitting and/or receiving unit and a communication system. The present invention seeks to provide a method, an emitting and/or receiving unit and a communication system for the efficient, resource saving and energy saving transmission of data to a group of receivers of a point-to-multipoint service. To this end, a point-to-multipoint service is carried out as an extension of a broadcast service CBS in a multi-layer protocol system, providing a multimedia transmission and/or a multicast service, preferably in the form of a multimedia broadcast/multicast service MBMS, during the distribution and/or planning of the use of system resources and the use of a discontinuous reception DRX.
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.

A method is provided for allocating physical transmission channels in a mobile radio cell, in which a base station, linked with a node of a mobile communication network; and a number of mobile terminals are present. In all mobile terminals and in the node of the mobile communication network the UMTS protocol architecture is implemented for at least the layer (2) and the layer (3) of the UMTS layer model. In at least one group of mobile terminals the physical transmission channel to be used for a multicast service is signaled for every mobile user terminal from the base station of the mobile radio cell. The present invention seeks to make the allocation of physical transmission channels in a mobile radio cell for a multicast service more efficient. Signaling of the allocation of a physical transmission channel to one of the mobile user terminals of the group from the node of the mobile communication network is carried out via the base station to the mobile user terminal by a general physical channel and system information is made available in advance to the group of mobile user terminals. The system information contains the configurations of the physical transmission channels for the multicast service and of the general physical channel. The system information further contains the information that the signaling of the allocation of the physical transmission channels is carried out on the general physical channel.

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:
Data packets are transmitted via a radio interface, wherein a control unit of a first entity transmits information via its logical channels serving as service access points in the form of a configuration message, with the configuration message including information about which logical channels are to be mapped onto which transport channels serving as service access points for a bit transmission layer. A set of transport formats are predetermined for each of the transport channels along with a set of permitted combinations of transport formats for all transport channels. Each transport format includes a set of parameters determining transmission characteristics of the transport channel configured with the corresponding transport format. The first entity selects a transport format for each of the transport channels, such that the resulting combination of transport formats corresponds to one of the transport combinations defined as permissible and wherein the first entity transmits the data to initiate the transmission of the data packets.

The invention is characterized in that for the purpose of sending an information to at least one group (MC1) of one or more subscriber devices of a radio communication system (FCS) regarding the presence of at least one group message (GN1) at least one common group paging indicator signal (GPI1) is additionally transmitted by one network element (BS1) to the subscriber devices of the respective group (MC1) and displayed.

A method is provided for transmitting user data messages from a network element of a radio communication system via at least one transmission channel to at least one subscriber terminal of the radio communication system, whereby the form of the user data messages is announced before the transmission thereof via planning information. The planning information includes a first planning message by which the transmission of the user data messages is announced via a first separate transmission channel, and a second planning message by which description information is transmitted via at least one second transmission channel, the description information indicating the form of the user data messages to be transmitted. The form of the user data messages to be transmitted can include the data type and/or the codification of the user data messages. Announcing the form of the user data messages in the planning information enables the subscriber terminal to only intercept or receive the user data messages that it can actually process, thus enabling energy to be saved during reception and processing.

摘要:
In a third generation (UMTS) mobile radiotelephone system, data are transmitted between a base station and a mobile station in packet form via the air interface. A connection control protocol with the task of, inter alia, establishing whether and which of the data packets have been lost during the transmission, using control data, functions in both stations. These control data are added to each packet that is sent by the connection control protocol. Several packets can be transmitted within the transmission interval and the number of packets can vary from interval to interval. This allows different data transmission rates. The inventive method enables the number of packets that are sent via the air interface to be reduced, by transmitting larger, rather than more, packets within a predetermined interval, while not affecting the possibility of varying the data transmission rate.
