Abstract
The present invention relates to a method of transmitting digital data messages in predetermined time slots within fixed length time frames from at least one of a plurality of subscriber units to a base station for reception, in which, selectively, subscriber units which are members of one or more predetermined classes of subscriber units are restricted from transmitting at least one predetermined type of message. This advantageously helps in avoiding overload of the network. The invention also relates to corresponding communication means.
