Abstract

A scheme for redirecting messages between an Internet Service Provider (ISP) host and a mobile device associated with a user having a mail address at the ISP host. An embodiment comprises one or more of the following: receiving incoming messages directed to the user'"'"'s mail address at the ISP host; responsive to a setting of a redirection trigger associated with the user, encrypting and redirecting the incoming messages from the ISP host to the mobile device via a redirector that is integrated with the ISP host; receiving encrypted outgoing messages that are generated and encrypted at the mobile communications device; decrypting the received encrypted outgoing messages to recover the outgoing messages; and configuring address information of the outgoing messages so that the user'"'"'s mail address is used as an originating address of the outgoing messages.

Claims

1. A method for redirecting messages between an Internet Service Provider (ISP) host system and a mobile device associated with a user, the user having a mail address at the ISP host system, the method comprising:

receiving incoming messages directed to the user'"'"'s mail address at the ISP host system;

responsive to a setting of a redirection trigger associated with the user, encrypting and redirecting the incoming messages from the ISP host system to the mobile device via a redirector host system, wherein the redirector host system is integrated with the ISP host system;

receiving encrypted outgoing messages that are generated and encrypted at the mobile communications device;

decrypting the received encrypted outgoing messages to recover the outgoing messages; and

configuring address information of the outgoing messages so that the user'"'"'s mail address is used as an originating address of the outgoing messages.

2. A system for redirecting messages between an Internet Service Provider (ISP) host and a mobile device associated with a user, the user having a mail address at the ISP host, the system comprising:

means for receiving incoming messages directed to the user'"'"'s mail address at the ISP host;

means, responsive to a setting of a redirection trigger associated with the user, for encrypting and redirecting the incoming messages from the ISP host to the mobile device via a redirector that is integrated with the ISP host;

means for receiving encrypted outgoing messages that are generated and encrypted at the mobile communications device;

means for decrypting the received encrypted outgoing messages to recover the outgoing messages; and

means for configuring address information of the outgoing messages so that the user'"'"'s mail address is used as an originating address of the outgoing messages.
