Abstract

The present invention relates to methods, apparatuses and a system in connection with pushing of packet data from an originator to a wireless communication station 20. When a network address is received by the wireless station 20 from a server 50 wishing to push packet data to the wireless station, the received network address is checked against stored predefined network addresses. If the received network address is found among the stored network addresses, the originator is verified, preferably by using an address translation server 40. Thus, in this way it can be determined that the originator indeed belongs to a predefined set of originators from which a mobile user wants to accept pushed packet data transmissions. A packet data session is then established by the wireless station with a verified originator in order to receive the packet data.

Claims

1. A method at a wireless communication station, the station being operatively associated with a wireless communication network providing packet data transferring services, the method comprising:

receiving a network address of an originator of packet data;

verifying the identity of the originator, if the received network address matches a predefined network address included in a set of one or more predefined network addresses stored by the wireless communication station; and

establishing, if the originator is authentic, a packet data session with the originator in order to facilitate transfer of packet data from the originator,

thereby ascertaining that pushed packet data only is received from one or more predefined originators.

2. The method as claimed in

claim 1

, wherein each of said predefined network addresses of said set is associated, within the wireless communication station, with a name of a network server from which it is desired to receive packet data.

3. The method as claimed in

claim 1

, wherein said verifying act includes:

establishing a packet data session with an address translation server;

requesting translation of the network address to a corresponding name of a network server; and

determining, bas ed upon the result of said translation, whether or not the network address is authentic.

4. The method as claimed in

claim 3

, wherein said determining act includes comparing the network server name returned by said address translation server with a previously stored network server name, the stored name being stored by the wireless communication station in such way that it is associated with the predefined network address matching said received network address.

5. The method as claimed in

claim 1

, wherein said network address of said receiving act is received in a short message, the short message being received from a short message service provided by said wireless communication network.

6. The method as claimed in

claim 1

, wherein said act of establishing a packet data session with the originator includes establishing a packet data session using the network address of said receiving act.

7. The method as claimed in

claim 1

, wherein said network address is an Internet Protocol address.

8. The method as claimed in

claim 3

, wherein said act of establishing a packet data session with the originator includes establishing a packet data session using the name of the network server, which name is returned by the translation server.

9. The method as claimed in

claim 3

, wherein said name of the network server is an Internet domain host name of the network server.

10. The method as claimed in

claim 1

, further including:

receiving a first originator identification code in said receiving act;

receiving a second originator identification code over the packet data session established with the originator; and

verifying, based on a comparison between the first and the second identification code, that the packet data session was established with the originator of the received network address.

12. A wireless communication station arranged to be operatively associated with a wireless communication network providing packet data transferring services, wherein the wireless communication station includes processing means, memory means and interface circuitry means for performing the acts recited in

claim 1

, thereby ascertaining that pushed packet data only is received from one or more predefined originators.

11. A computer-readable medium storing computer-executable components for causing a wireless communication station to perform the acts recited in claim I when the computer-executable components are run on microprocessor included by a wireless communication station.

13. A method of a system which includes a wireless communication station and an originator of information, the station being operatively associated with a wireless communication network providing packet data transferring services, the method comprising:

transmitting, from the originator to the wireless communication station, the originator'"'"'s own network address;

verifying, at the wireless communication station, the identity of the originator, if the received network address matches a predefined network address included in a set of one or more predefined network addresses stored by the wireless communication station; and

establishing, from the wireless communication station, and if the originator is determined by the wireless communication station to be authentic, a packet data session with the originator in order to facilitate transfer of packet data from the originator,

thereby ascertaining that pushed packet data only is received from one or more predefined originators

14. The method as claimed in

claim 13

, wherein each of the predefined network addresses of said set is associated, within the wireless communication station, with a name of a network server from which transfer of packet data to the wireless communication station is desired.

15. The method as claimed in

claim 13

, wherein said verifying act includes:

establishing, from the wireless communication station, a packet data session with an address translation server;

requesting, from the wireless communication station, translation of the network address to a corresponding name of a network server; and

determining, at the wireless communication station, and based upon the result of said translation, whether or not the network address is authentic.

16. The method as claimed in

claim 15

, wherein said determining act includes comparing, at the wireless communication station, the network server name returned by said address translation server with a previously stored network server name, the stored name being stored by the wireless communication station in such way that it is associated with the predefined network address matching said received network address.

17. The method as claimed in

claim 13

, wherein said network address of said transmitting act is transmitted by requesting a short message service provided by a wireless communication network to transmit a short message that includes said network address to the wireless communication station.

18. The method as claimed in

claim 13

, wherein said act of establishing a packet data session with the originator includes establishing, from the wireless communication station, a packet data session using the network address received as a result from said transmitting act.

19. The method as claimed in

claim 13

, wherein said network address is an Internet Protocol address.

20. The method as claimed in

claim 15

, wherein said act of establishing a packet data session with the originator includes establishing, from the wireless communication station, a packet data session using the name of the network server, which name is returned by the translation server in said verifying act.

21. The method as claimed in

claim 15

, wherein said name of the network server is an Internet domain host name of the network server.

22. The method as claimed in

claim 13

, further including:

transmitting a first originator identification code in said transmitting act;

transmitting, from the originator, a second originator identification code over the packet data session established between the wireless communication station and the originator; and

verifying, at the wireless communication station, and based on a comparison between the first and the second identification code, that the packet data session was established with the originator of the network address received in said transmitting act.

23. A system including a wireless communication station and at least one originator server, the station being operatively associated with a wireless communication network providing packet data transferring services, wherein the system is arranged to perform the acts recited in

claim 13

, thereby ascertaining that the wireless communication station only receives pushed packet data from one or more predefined originators.
