Abstract:
1. A wireless terminal method comprising: (a) providing a memory on the wireless terminal which, in an on-line mode occurring when there exists a session over an active link between the wireless terminal and a server, is adapted to be treated as local virtual memory by an application program running on the server to read and write data in the virtual memory related to the application program; and (b) providing a local application program on the wireless terminal which, in an off-line mode occurring when there does not exist a session over an active link between the wireless terminal and the server, has read and write access to the data in the virtual memory; wherein in the off-line mode, when the application program running on the server modifies data at the server, the application program running on the server thereafter establishes a data session with the wireless terminal and updates corresponding data in the virtual memory, and when the local application program modifies particular data in the virtual memory, the local application program initiates a data session with the server and outputs a message to the server, the message comprising updates for at least some of the particular data.
