ABSTRACT:
The invention concerns a method of operating a broadband link for the exchange of data (DAT) between a mobile terminal (MS) and a network-side mobile radio facility (MSC), as well as the mobile terminal (MS), the network-side mobile radio facility (MSC) and a mobile radio system. Two or more radio channels to the mobile terminal (MS) are established and assigned as subchannels (C1 to CN) to the broadband link. The data (DAT) are then transmitted via the subchannels (C1 to CN) between a terminal-side entity (ENMT) and a network-side entity (ENNET) of a communications layer (L2), where the entities (ENMT, ENNET) exchange the data (DAT) as data packets (FRDAT1, FRDAT2) in accordance with a transmission protocol, and control the distribution of the stream of data packet to the subchannels (C1 to CN) as well as its recombination. The protocol (PROT) defines and supports two or more different packet types for transportation of the data. The entities (ENMT, ENNET) recognize these different packet types and process them differently as different logical channels (LC1, LC2) of the same communications layer (L2).
