Abstract
Methods for synchronizing PIM data between a wireless telephone and a synchronization server. A communication in interface is established between the telephone and the server, using a wireless network and the Internet. The telephone initiates the synchronization by placing a data call to the server and logging on to the server. A sync client within the telephone sends recent changes to its dataset to the server and requests an acknowledgement of these changes. In an acknowledgement message, the server specifies which changes were actually received. Based on this acknowledgment, the client continues resending changes until it receives confirmation that the server has received all of its changes. The server performs conflict and duplicate resolution between the changes received from the client and other changes of which the server is aware, and enters into its dataset those changes that survive the resolutions. The client also requests that the server send changes that have been made to the server's dataset. The server identifies all changes that should be sent to the client and that have survived the conflict and duplicate resolutions. The server then sends its changes to the client…
