E-mail messaging to/from a mobile terminal
View Patent ↗Systems and methods for sharing an e-mail address between a host system ( 100 ) and a mobile terminal ( 102 ) addressable by a temporary wireless identity ( 122 D) in an access network ( 114 ). A terminal identifier ( 122 A) is assigned to the mobile terminal ( 102 ) or its user. The system comprises a connectivity function ( 600 ) and a messaging centre ( 110 ) that collectively maintain an association ( 610, 612 ) between the terminal identifier ( 122 A), encryption information ( 122 C) and the temporary wireless identity ( 122 D). When detecting an e-mail message addressed to the terminal identifier ( 122 A), the connectivity function encrypts the e-mail message with the encryption information ( 122 C). The messaging centre determines the temporary wireless identity ( 122 D) of the mobile terminal and transmits the encrypted e-mail message to the mobile terminal which receives and decrypts the encrypted e-mail message.
1. A system for forwarding an e-mail message, the system comprising:
a connectivity application executable by a processor in a data network to:
detect the e-mail message at an e-mail server,
encrypt at least part of the e-mail message, and
send the encrypted e-mail message; and
a messaging centre configured to receive the encrypted e-mail message from the connectivity application and to transmit the encrypted e-mail message via an access network to a mobile terminal for decryption, the access network establishing a tunnel between the messaging centre and the mobile terminal, the mobile terminal having an e-mail address under the e-mail server and a permanent terminal identity assigned to the mobile terminal and a temporary identity in the access network, the temporary identity based on an identifier of the tunnel to the mobile terminal.
2. The system of claim 1 , wherein the messaging centre is further configured to pack the at least part of the e-mail message before transmission to the mobile terminal and to unpack the at least part of the e mail message after transmission to the mobile terminal.
3. The system of claim 2 , wherein the messaging centre is further configured to pack the at least part of the e-mail message by omitting the e-mail address.
4. The system of claim 1 , further comprising the mobile terminal, the mobile terminal being configured to generate encryption information and to convey the encryption information via a secure channel to the connectivity application after authentication.
5. The system of claim 1 , wherein the mobile terminal is further configured to generate a control message relating to the e-mail message and indicating one of the following operations: marking the e-mail message as read or unread or deleting the e-mail message and wherein the e-mail server responds to the control message by marking the e-mail message as read or unread when the control message indicates marking the e-mail message as read or unread and moving the email message to a folder containing deleted e-mail messages when the control message indicates deleting the messages.
6. The system of claim 1 , wherein the messaging centre is further configured to identify the e-mail message using the e-mail address the permanent terminal identity, and the temporary identity.
