Abstract: 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.

Abstract: A communication link from a first telecommunication device to a second telecommunication device is established via a telecommunication network. Initially, a plurality of multi-media objects, which are associated with a first telecommunication subscriber, are stored together with a respective reference number in the telecommunication network. An allocation representation of at least one data set is also determined, the representation indicating a specific call receiver with reference to a specific reference number of a multi-media object. Subsequently, a link set up request is sent from the first telecommunication device associated with the first telecommunication subscriber to the telecommunication network, the link set up request indicating that a communication link should be set up between the first telecommunication device and the second telecommunication device associated with a selected call receiver.
