Currently, PDA devices run software for items such as PIM (Personal Information Management) and email. An example of a program that runs on a PDA and provides PIM and email support is the WEA (Websphere Everyplace Access) client. On these devices the PDA user must initiate a "sync" whenever he/she wants to synchronize data from the server. A full scale data sync can take an enormous amount of time. If there are not updates on the server then this time was wasted. Proposed disclosure describes a method where information server will alert the client for updates are needed.

Server initiated alerts to improve PDA user efficiency.

This invention describes a method for an information server to initiate an alert to a client in the situation when there is new data on the server, such as a new email message. The client can then provide a visual clue to the end user telling him/her that they should provide a data sync with the server.

The following describes a possible implementation that could provide this enhancement would be to run a UDP socket server on the WEA (Websphere Everyplace Access) server. When the WEA client first comes up it sends a UDP message over to the server informing it of its existence and provides a UDP port that it is listening on. Whenever the server had new data that is directed for that client it can send a simple UDP message that serves as an alert to the client. The client can provide a visual cue to the end user that tells the user that it should synchronize with the server.

Although at a high level INS (Intelligent Notification Service) and proposed method have similarities, but there are several key differences between two and they are described as follows.

Today two systems, one being a client and the other a server, coordinate (synchronize) transfers of information based on long, negotiated synchronization protocols. These synchronization protocols often take minutes to establish. Once established, the synchronization between the two systems can initiate.
