Abstract

A method is described for processing a request message sent from a mobile radio terminal to a message filter processor, in which a request message, in which one or more electronic peer-to-peer files is/are requested, is detected by the message filter processor (102,103,104. The request message is used to create a peer-to-peer request message according to a predefined peer-to-peer communication protocol. The peer-to-peer request message is sent to at least one processor (201 . . . 207) in a fixed network communication network (200), the request message being present in the form of a data packet (300), having a packet header (301) and user data (302), and detection of the request message including reading data in the packet header (301) of the request message, the data being used to identify a specific peer-to-peer application.

Claims

1. Method for processing a request message sent from a mobile radio terminal (101) of a mobile radio communication network (100) to a message filter processor (102,103,104), in which

a request message, in which one or more electronic peer-to-peer files is/are requested, is detected by the message filter processor (102,103,104),

the request message is used to create a peer-to-peer request message according to a predefined peer-to-peer communication protocol,

the peer-to-peer request message is sent to at least one processor (201 . . . 207) in a fixed network communication network (200), and

the request message is present in the form of a data packet (300), having a packet header (301) and user data (302), detection of the request message including reading data in the packet header (301) of the request message, the data being used to identify a specific peer-to-peer application.

2. Method according to claim 1,

characterized in that

the packet header (301) has at least a first data area (303) with a predefined data format and at least a second data area (304) with a non-predefined data format and the identification data is stored in a data area with a non-predefined data format.

3. Method according to claim 1,

characterized in that

the data packet is a type IPv6 data packet.

4. Method according to claim 2,

characterized in that

the second data area (304) is the flow label.

5. Method according to claim 1,

characterized in that

communication in the fixed network communication network (200) is based on Internet protocols.

6. Method according to claim 1,

characterized in that

detection of the request message takes place in the mobile radio communication network.

7. Method according to claim 1,

characterized in that

a destination address, to which the requested peer-to-peer files are to be sent, is detected from the request message of the mobile radio terminal (101) and further processed.

8. Method according to claim 7,

characterized in that

the destination address is integrated in the data of the second data area (304) of the data packet.

9. Method according to claim 7,

characterized in that

the destination address is assigned to a peer-to-peer application and stored in an assignment table in a message filter processor (102,103,104), in which the request message is detected.

10. Method according to claim 7,

characterized in that

when reading and analyzing the second data area (303) of the data packet (300), it is verified whether the request for the peer-to-peer files is permitted in respect of a predefined permissibility criterion and the request is rejected if it is not permitted.

11. Method according to claim 10,

characterized in that

verification takes place using the destination address.

12. Method according to claim 7,

characterized in that

the request message undergoes an authorization verification and the request message is only processed further if the request message satisfies predefinable authorization criteria.

13. Method according to claim 7,

characterized in that

the request message undergoes an authentication verification and the request message is only processed further if the request message satisfies predefinable authentication criteria.

14. Computer program product with codes to implement the method according to claim 7.

15. Communication system for processing a request message sent from a mobile radio terminal (101) of a mobile radio communication network (100) to a message filter processor (102,103,104), in which the message filter processor (102,103,104) is set up to,

detect a request message, which is present in the form of a data packet (300), having a packet header (301) and user data (302), in which one or more electronic peer-to-peer files is/are requested, detection of the request message including reading data in the packet header (301) of the request message and the data being used to identify a specific peer-to-peer application,

use the request message to create a peer-to-peer request message according to a predefined peer-to-peer communication protocol, and

send the peer-to-peer request message to at least one processor (201 . . . 207) in a fixed network communication network (200).
