An USSD transporting method (200) and mobile computing device (410) are described. The method (200) can include the steps of: providing a data pushing operation (210) over a universal supplementary services data (USSD) channel from the application server to the mobile device client; and initiating a data pulling operation (220) over an internet protocol (IP) channel by the mobile device client, in response to the pushing operation. Advantageously, for short data transfers, such as application server push notifications, USSD messages require lower power drain than packet data, due to the longer time to transition to an RRC idle state after the data transfer is completed. Also, push notifications can be sent over USSD without an open IP session, thereby saving the client from having to maintain a persistent IP session, while employing alternate pulling transport means such as wireless LAN which require lower power drain than a wide area network. |
