Abstract
A channel configuration of a digital mobile system comprises two or more lower-rate transmission channels for each high-speed radio interface traffic channel at the network interface between a base station and an interworking function. Radio frames, such as EDGE frames, are transferred on a radio interface traffic channel. Transmission frames, such as TRAU frames, are transferred on transmission channels. The total data rate at the network interface is greater than the data rate at the radio interface. According to the invention, the total data rates of the network interface and the radio interface are rate-adapted by transferring fill data in transmission frames in addition to payload between the base station and the interworking function, such that the average data rate of the payload at the network interface corresponds to the total data rate at the radio interface, and the combined total data rate of the fill data and the payload corresponds to the total data rate at the network interface.
