Method of operating a broadband link between a mobile terminal and a network-side mobile radio facility, as well as mobile terminal, network-side mobile radio facility, and mobile radio system
First Claim
1. A method of operating a broadband link for exchanging data (DAT) between a mobile terminal (MS) and a network-side mobile radio facility (MSC), comprising the steps of establishing two or more radio channels (RC1 to RCN) to the mobile terminal (MS) via a radio interface (RI), assigning said radio channels (RC1 to RCN) as subchannels (C1 to CN) to the broadband link, and transmitting the data (DAT) between a terminal-side entity (ENMT) and a network-side entity (ENNET) of a communications layer (L2) via the subchannels (C1 to CN), the entities (ENMT, ENNET) exchanging the data (DAT) as data packets of a data packet stream in accordance with a communications protocol (PROT) and controlling both a distribution of the data packet stream among the subchannels (C1 to CN) and a recombination of the data packet stream, characterized in that the protocol (PROT) defines and supports two or more different packet types (FRDAT1, FRDAT2) for data transport, and that the entities (ENMT, ENNET) recognize the different packet types and process them as different logical channels (LC1, LC2) of said communications layer (L2) in different ways.

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).
