Method for bidirectional data transmission via a packet-oriented network device

1. A telecommunications system for transmission of a data set from a data transmission device to a data reception device via at least one packet-oriented network device over which data is transmitted in a packet-oriented manner, said system comprising:

a connection-oriented transmission mode for the transmission of the data set from supported connection-oriented transmission and packet-oriented transmission modes;

a data encapsulation protocol adapted to be allocated to the data set to be transmitted for encapsulation of the data set to enable a connection-oriented transmission of the data set;

an encapsulated data set for receipt following transmission over an air interface;

a base station of a mobile phone network;

wherein said base station is configured to evaluate the data encapsulation protocol of the encapsulated data set and unpack the encapsulated data set to produce an unpacked data set,

said base station further configured for packet-oriented transmission of the unpacked data set to said at least one packet-oriented network device; and

wherein said at least one packet-oriented network device is configured for 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.

2. The telecommunications system according to claim 1 , wherein the base station supports both a connection-oriented data transmission and a packet-oriented data transmission.

3. The telecommunications system according to claim 1 , wherein the allocation of the data encapsulation protocol is made in a device connected to a mobile terminal.

4. The telecommunications system according to claim 1 , wherein the allocation of the data encapsulation protocol is made in a mobile terminal.
