Abstract

Efficient distribution of work from a server to remote/mobile nodes is provided by a hierarchy of Session Work Objects into which events can be assigned. Session Work Objects can also be assigned to other Session Work Objects in the hierarchy. Session Work Objects can then be assigned to sessions, nodes, or users. Small numbers of related events can be grouped together, thereby simplifying the distribution of work.

Claims

1. A method for distributing work from a data processing server to a plurality of remote/mobile data processing nodes which are temporarily and intermittently linked to said server for communication therebetween, said work distributing method comprising the steps of:

providing in said server a plurality of events, each of which define at least one action which is performed in a remote/mobile communication between said server and a node;

grouping selected events into Electronic Software Distribution Session Work Objects for regularly updating files which are distributed during remote/mobile communications;

grouping selected events into Worklist Session Work Objects for defining tasks to be performed during remote/mobile communications;

grouping selected Electronic Software Distribution Session Work Objects and selected Worklist Session Work Objects into Group Session Work Objects;

defining a plurality of sessions to specify times for linking a node to said server for remote/mobile communications therebetween;

assigning selected Group Session Work Objects to sessions such that said selected Group Session Work Objects execute when a session is executed;

assigning selected Group Session Work Objects to selected nodes, such that said selected Group session Work Objects execute when a node is linked to said server for remote/mobile communications therebetween; and

causing said Electronic Software Distribution, Worklist and Group Session Work Objects to execute on said server to thereby effect remote/mobile communications between said server and said nodes.

2. A method according to claim 1 further comprising the steps of:

grouping selected Electronic Software Distribution Session Work Objects and selected Worklist Session Work Objects into Application Session Work Objects;

assigning selected Application Session Work Objects to selected users; and

assigning selected users to selected nodes;

wherein said causing step comprises the step of causing said selected Application Session Work Objects to execute on said server.

3. A method according to claim 1 further comprising the step of:

assigning selected Electronic Software Distribution and Worklist Session Work Objects directly to sessions such that said selected Electronic Software distribution and Worklist Session Work Objects also execute when a session is executed.

4. A method according to claim 3 further comprising the step of:

assigning selected Electronic Software Distribution and Worklist Session Work Objects directly to nodes such that said selected Electronic Software distribution and Worklist Session Work Objects also execute when a node is linked to said server for remote/mobile communications therebetween.

5. A method according to claim 2 further comprising the steps of:

grouping selected Application Session Work Objects into Group Application Session Work Objects; and

assigning selected Application Group Session Work Objects to selected users.

6. A method according to claim 1 further comprising the step of grouping selected Worklist Session Work Objects into selected Group Session Work objects.

7. A method according to claim 1:

wherein said providing step comprises the step of providing a plurality of events including file transfer events, operating system events, session control events and server events;

wherein said step of grouping selected events into Electronic Software Distribution Session Work Objects comprises the step of grouping selected file transfer events into Electronic Software Distribution Session Work Objects;

and wherein said step of grouping selected events into Worklist Session Work Objects comprises the step of grouping selected file transfer events, operating system events, session control events and server events into Worklist Session Work objects.

8. A method according to claim 1 further comprising the step of assigning a priority value to said Electronic Software Distribution, Worklist and Group Session Work Objects, and wherein said causing step comprises the step of causing said Electronic Software Distribution, Worklist and Group Session Work Objects to execute on said server in priority order to thereby effect remote/mobile communications between said server and said nodes.

9. A method according to claim 1 further comprising the step of assigning an execution time period to said Electronic Software Distribution, Worklist and Group Session Work Objects, and wherein said causing step comprises the step of causing said Electronic Software Distribution, Worklist and Group Session Work Objects to execute on said server during the assigned execution time period to thereby effect remote/mobile communications between said server and said nodes.

10. A method according to claim 1 further comprising the step of assigning an activation and deactivation time to said Electronic Software Distribution, Worklist and Group Session Work Objects, and wherein said causing step comprises the step of causing said Electronic Software Distribution, Worklist and Group Session Work Objects to execute on said server from the assigned activation time until the assigned deactivation time, to thereby effect remote/mobile communications between said server and said nodes.

11. A method according to claim 1 further comprising the step of causing said sessions to execute on said server to thereby effect remote/mobile communications between said server and said nodes.

12. A method according to claim 11 wherein said step of grouping Selected events into Electronic software Distribution Session Work objects further comprises the step of tagging each of said events for execution before a remote/mobile communication link is established, while said remote/mobile link is established or after said remote/mobile communications link is disconnected.

13. A method according to claim 12 wherein said step of causing said sessions to execute on said server comprises the steps of:

executing events which are tagged for execution before a remote/mobile link is established;

establishing a remote/mobile link;

executing events which are tagged for execution while said remote/mobile link is established;

disconnecting said remote/mobile link; and

executing events which are tagged for execution after said remote/mobile link is disconnected.

14. A system for distributing work from a data processing server to a plurality of remote/mobile data processing nodes which are temporarily and intermittently linked to said server for communication therebetween, said work distributing system comprising:

a plurality of events in said server, each of which define at least one action which is performed in a remote/mobile communication between said server and a node;

means for grouping selected events into Electronic Software Distribution Session Work Objects for regularly updating files which are distributed during remote/mobile communications;

means for grouping selected events into Worklist Session Work Objects for defining tasks to be performed during remote/mobile communications;
