ABSTRACT:
The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel or independent signalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling. The parameters of the selection rule used in the logical channel selection can include, for example, the effect of the use of the logical channels on the quality of service of the connection which uses the traffic channel, the current usage rate of the logical channels, the number and priority of messages to be sent, and an estimate of the number and priority of messages to be sent in the near future.
