Method for transmitting digital useful data
First Claim
1. A method for transmitting useful data from a first mobile station (1) to a second mobile station (5), in which for transmission in a first telecommunication network (10), the first mobile station (1) source encodes useful data in a first step and then channel encodes the useful data in a second step;
- the useful data encoded in the first and second steps are transmitted in the form of a first bit stream to an intermediary station (15) via a transmission channel of the first telecommunication network (10);
the useful data channel encoded in the second step presented in the first bit stream are channel decoded by the intermediary station (15);
for transmission in a second telecommunication network (20), the useful data are channel encoded by the intermediary station (15) and the useful data thus channel encoded are transmitted to a second mobile station (5) via a transmission channel of the second telecommunication network (20), signalization data are transmitted from the intermediary station (15) to the second mobile station (5), said signalization data containing information regarding the type of encoding of the useful data in the first step, the useful data channel encoded in the intermediary station are channel decoded by the second mobile station (5), and then the useful data channel decoded by the second mobile station (5) are source decoded by the second mobile station (5), according to the signalization data received by the second mobile station (5).

Abstract
The method for transmitting useful digital data from a first (1) to a second mobile station (5) saves computing costs and prevent data loss. In this method for transmission in a first network (10), the first station (1) source encodes useful data in a first step and then channel encodes the source encoded useful data in a second step. The encoded useful data are transmitted as a first bit stream to an intermediary station (15) via a transmission channel of the first network (10). The encoded useful data in the first bit stream are channel decoded by the intermediary station (15). For transmission in a second network (20), the useful data are again channel encoded by the intermediary station (15) and are transmitted to a second mobile station (5) via a transmission channel of the second network (20). Signalization data containing information regarding the encoding in the first step are transmitted from the intermediary station (15) to the second mobile station (5). The useful data coded in the second step are channel decoded by the second mobile station (5). The resulting channel decoded useful data are then source decoded by the second mobile station (5) according to signalization data received by the second mobile station (5).
