Abstract

Offenbart ist eine Telekommunikationsanordnung zum Übertragen von Sprachsignalen. Die Telekommunikationsanordnung umfasst dabei ein Funkkommunikations-Netzwerk (FKN) zum Vermitteln von Sprachsignalen zwischen Mobilstationen, wobei das Funkkommunikations-Netzwerk eine erste Einrichtung (VED1) zum Verarbeiten von Sprachsignalen hinsichtlich deren Qualität aufweist. Ferner umfasst die Telekommunikationsanordnung eine erste (MS1) und eine zweite (MS2) Mobilstation, die dafür ausgelegt sind, Sprachsignale über das Funkkommunikations-Netzwerk zueinander zu übertragen, wobei ferner zumindest eine der beiden Mobilstationen eine zweite Einrichtung (VED2) zum Verarbeiten von Sprachsignalen hinsichtlich deren Qualität aufweist. Zur Vermeidung einer doppelten Verarbeitung von Sprachsignalen hinsichtlich deren Qualität, welche zu einer Verschlechterung der Qualität der Sprachsignale führen würde, umfasst eine der Mobilstationen, welche die zweite Einrichtung zum Verarbeiten von Sprachsignalen aufweist, ferner eine erste Steuereinrichtung (ST1), welche dafür ausgelegt ist, ein erstes Steuersignal (STS1) an das Funkkommunikations-Netzwerk zu senden, damit dieses die erste Einrichtung (VED1) zum Verarbeiten von Sprachsignalen deaktiviert.Disclosed is a telecommunication arrangement for transmitting speech signals. The telecommunication arrangement in this case comprises a radio communication network (FKN) for switching voice signals between mobile stations, the radio communication network having a first device (VED1) for processing speech signals with regard to their quality. Furthermore, the telecommunication arrangement comprises a first (MS1) and a second (MS2) mobile station, which are designed to transmit voice signals to one another via the radio communication network, and at least one of the two mobile stations comprises a second device (VED2) for processing speech signals whose quality has. In order to avoid a double processing of speech signals with regard to their quality, which would lead to a deterioration of the quality of the speech signals, one of the mobile stations, which has the second device for processing speech signals, furthermore comprises a first control device (ST1), which is designed send a first control signal (STS1) to the radio communication network to disable the first means (VED1) for processing voice signals.
