Abstract
The data stream between the transcoders (TCE1, TCE2) of a mobile wireless system is subdivided into a first data stream with samples for transmission and a second data stream with signal parameters for reconstruction of user data and/or for signaling. Both data streams are transmitted at the same time in particular in a handshake phase. The invention permits an improvement in the quality of transmitted data, e.g., speech data in a GSM network in tandem operation between mobile subscribers, in particular during a handshake phase.

Method of transmitting data, specifically GSM data, between a calling subscriber (Tl1) and a called subscriber (Tl2), using a predetermined frame format for the transmission with the following measures:
- The data stream between transcoders (TCE1, TCE2) assigned to the subscribers (Tl1, Tl2) is subdivided into a first data stream with samples for transmission and a second data stream with signal parameters for reconstruction of user data and/or for signaling, which are provided for transparent switching, the data streams so divided being transmitted simultaneously during a handshake phase.
