Abstract
A method and system for transmitting electronic messages. The system includes a messaging application executing on a computer. The messaging application is operable to receive from a message sender an electronic message having an attachment associated therewith, operable to communicate the electronic message to the mobile communication device via a first wireless data path and operable to communicate the attachment associated with the electronic message to the mobile communication device via a second wireless data path having a higher bandwidth than the first wireless data path.
Claims16
A method of operating a mobile communication device, the method comprising:
- maintaining a first wireless data path to an application server via a first wireless packet data service network, the first wireless data path being a secure end-to-end continuous communication link;
- receiving an electronic message and an attachment notification via the first wireless data path;
- and
- in an automatic mode, establishing a second wireless data path for transmission of the attachment to the mobile communication device when the mobile communication device is within a coverage area for a given radio access technology with which the device is configured to establish the second wireless data path;
- wherein the second wireless data path is a secondary PDP context of higher quality of service than the first wireless data path.
A mobile communication device comprising:
- a communications subsystem containing a transmitter and a receiver;
- a module operable to maintain a first wireless data path to an application server via a first wireless packet data service network, the first wireless packet data service network being a secure, end-to-end continuous communications link;
- a module operable to receive an electronic message and an attachment notification via the first wireless data path;
- and
- a module operable, in an automatic mode, to establish a second wireless data path for transmission of the attachment responsive to determining that to the mobile communication device the mobile communication device is within a coverage area for a given radio access technology with which the device is configured to establish the second wireless data path
- wherein the second wireless data path is a secondary PDP context of higher quality of service than the first wireless data path.
