Method for the bi-directional transmission of data via a packet-oriented network device

A method for transmission of a data set between a data transmission device and a data reception device via at least one packet-oriented network device over which data is transmitted in a packet-oriented manner, the method having the following steps:

• a) selection of a connection-oriented transmission mode for the transmission of the data set from supported connection-oriented transmission and packet-oriented transmission modes;
• b) allocation of a data encapsulation protocol to the data set to be transmitted for encapsulation of the data set to enable a connection-oriented transmission of the data set;
• c) encapsulation of the data set to form an encapsulated data set;
• d) connection-oriented transmission of the encapsulated data set over an air interface from a mobile phone to a base station of a mobile phone network;
• e) evaluation of the data encapsulation protocol of the encapsulated data set in a radio network controller associated with said base station and unpacking in said radio network controller of the encapsulated data set to produce an unpacked data set;
• f) packet-oriented transmission of the unpacked data set from the radio network controller to said at least one packet-oriented network device;
• and
• g) packet-oriented transmission of the data set from the at least one packet-oriented network device via a packet network to the data reception device.
