Abstract

A method is provided for the instant transfer of packet switched data corresponding to at least one data content type between at least two terminals connected to each other by a packet switched network. An information element which is specific to the at least one data content type is transmitted to each element of the network involved in the communication link when a communication link is set up between the at least two terminals.

Claims

1-7. -7. canceled.

8. A method for immediate transmission of packet switched data of at least one data content type between at least two terminals connected to one another via a packet switching network, the method comprising the steps of:

providing that the data contains information about an availability of users of the at least two terminals;

setting up a communication link between the at least two terminals; and

transmitting an information element which is specific for the at least one data content type to each element of the network involved in the communication link.

9. A method for immediate transmission of packet switched data as claimed in claim 8, wherein the network is equipped with one of GPRS and UMTS, and includes network elements Gateway GPRS Support Node and Serving GPRS Support Node.

10. A method for immediate transmission of packet switched data as claimed in claim 8, wherein the information element is an end user address information element which includes a packet data protocol type number specific for the at least one data content type.

11. A method for immediate transmission of packet switched data as claimed in claim 8, wherein the data contains messages.

12. A method for immediate transmission of packet switched data as claimed in claim 8, wherein the data contains information about at least one associated group of users of the at least two terminals.

13. A method for immediate transmission of packet switched data as claimed in claim 8, wherein the data contains information about a capability for joint use of at least one file, which is stored in the network, by at least one associated group of users of the at least two terminals.

14. A method for immediate transmission of packet switched data as claimed in claim 8, wherein at least two data content types are provided, with each data content type being associated with a different information element.
