First Claim
1. A method for transmitting data between a mobile client and a cellular network, wherein the mobile client is connected to an ad-hoc network and communicates via the ad-hoc network with a mobile relay that is connected to the ad-hoc network and the cellular network and wherein the mobile relay relays data that are transmitted from the mobile client towards the cellular network and/or data that are transmitted from the cellular network towards the mobile client whereinthe cellular network transmits data dedicated to the mobile relay and dedicated to the mobile client within the same data stream;
- the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile relay itself and terminates the part of the received data that is dedicated to the mobile relay itself;
the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile client and forwards the part that is dedicated to the mobile client to the mobile client; and
the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the cellular network and forwards the part that is dedicated to the cellular network to the cellular network.

Abstract
To reduce the overhead induced by transmitting data between a mobile client and a cellular network via an ad-hoc network extension, the cellular network transmits data dedicated to the mobile relay and dedicated to the mobile client within the same data stream, the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile relay itself and terminates the part of the received data that is dedicated to the mobile relay itself, the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile client and forwards the part that is dedicated to the mobile client to the mobile client, and the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the cellular network and forwards the part that is dedicated to the cellular network to the cellular network.
