Abstract

A method for forwarding an e-mail message from an e-mail server to a mobile terminal is provided. An e-mail address of the mobile terminal is associated with an identifier and encryption information, receiving the e-mail message associated with the e-mail address and sent by the e-mail server. The method includes encrypting the e-mail message using the encryption information associated with the e-mail address and transmitting the encrypted e-mail message to the mobile terminal.

12. The first mobile device of claim 1, wherein the encryption key is closely related to the displayed service activation code.

13. The first mobile device of claim 1, wherein the first mobile device is further operable for storing an association between at least two of the encryption key, the messaging account, an identifier of the second device, and the displayed service activation code.

14. The first mobile device of claim 1, wherein the encrypted message is sent to the second device through an intermediate device.

15. The first mobile device of claim 1, wherein a control message is received from the second device upon user interaction with the encrypted message.

16. The first mobile device of claim 1, wherein the encrypted message is sent to the second device over the cellular access network.

17. The first mobile device of claim 1, wherein the first mobile device is operable for establishing the encryption key for the second device.

18. The first mobile device of claim 1, wherein the first mobile device is operable for receiving the encryption key for the second device.

19. The first mobile device of claim 1, wherein the encryption key is unique for the second device.

20. The first mobile device of claim 1, wherein the message is addressed to a user of the first mobile device.

21. The first mobile device of claim 1, wherein the message is received from an e-mail server.

22. A method implemented on a first mobile device for sharing a messaging account, the method comprising:

authenticating a the first mobile device for access to the messaging account;

optically receiving a displayed service activation code from a second device;

registering the second device for access to the messaging account based on the displayed service activation code;

receiving a message for the messaging account;

encrypting the message using an encryption key; and

sending the encrypted message wirelessly to the second device, wherein;

the first mobile device is authenticated to access the messaging account prior to optically receiving the displayed service activation code; and

the first mobile device is configured to communicate over a cellular access network with a messaging centre.

23. The method of claim 22, wherein the displayed service activation code allows messaging access to the messaging account for the second device.

24. The method of claim 22, wherein the messaging account is an e-mail account.

25. The method of claim 22, wherein the second device is a mobile device.

26. The method of claim 22, wherein the displayed service activation code is received by the first mobile device in response to user input at the second device.

27. The method of claim 22, wherein the displayed service activation code is received by the first mobile device in an off-line communication.

28. The method of claim 26, wherein the off-line communication involves a local connection.

29. The method of claim 26, wherein the off-line communication prevents eavesdropping of the displayed service activation code.
