The invention relates to a method for guaranteeing the quality of a connection in a data-transmitting telecommunication system. In particular the invention relates to transmission of data through an Internet network, where at least one of the parties to the connection is a mobile station (101). According to the invention, a circuit-switched connection is set up in parallel with a packet-switched data transmission connection, and through that circuit-switched connection it is at least partly transmitted the data that requires a good transmission channel quality. Once such data type is speech data. In accordance with the invention, the circuit-switched connection is given an IP address of its own, which is used in connection establishment and data transmission. The circuit-switched connection may be realized through various arrangements in parallel with the packet-switched connection. |
