Abstract

In a communications network 1, a signalling of a communication packet is compressed by firstly determining a difference, (15,16) between a first and a second subsequent signalling portion/header. This difference is used to produce a bit mask (17) and this bit mask is transmitted with the data. If the bit mask for the next packet is the same (18/19), then an indication that this is the case is transmitted with the data. The bit mask is not transmitted. A receiver upon detecting the indication will use as the bit mask the earlier received one. Thus less information needs to be transmitted and the signalling portion is compressed in a first and a second stage of compression thus saving bandwidth.
