<p>The embodiments of the invention disclose a method, device and system for voice communication, wherein the method includes the following steps: a Radio Resource Management (RRM) unit of a Base Station Controller (BSC) receives a call request initiated by User Equipment (UE); the RRM unit obtains call configuration information according to the call request; the RRM unit sends a first message to a TransCoder (TC) of the BSC, wherein the first message includes the call configuration information; the TC judges whether the call configurations of the two ends of the call match each other, and if the result of the judgment is yes, the TC starts Tandem Free Operation (TFO) communication. With the embodiments of the invention, the configuration information is not transmitted in the form of stealing voice frames, therefore the transmission quality of voice information is guaranteed, the transmission time of configuration information is reduced, call delay is decreased, and call timeliness is increased.</p> |
