Abstract

A method and system for extended ordering of collections of data for synchronization over a wireless network, each collection having an existing priority level, the method having the steps of: adding, to each collection, a dependency field having a dependency value; exchanging the priority level and dependency value for each collection; and ordering synchronization of the collections based on priority levels and dependency values of the collections.

Claims

1. A method for extended ordering of collections of data for synchronization over a wireless network, each collection having an existing priority level, the method comprising the steps of:

adding, to each collection, a dependency field having a dependency value;

exchanging the priority level and dependency value for each collection; and

ordering synchronization of the collections based on priority levels and dependency values of the collections.

2. The method of claim 1, wherein the dependency field is eight bits.

3. The method of claim 1, wherein the exchanging is performed in a initialization packet.

4. The method of claim 1, wherein the ordering step orders the synchronization of the collections by priority level first and by dependency value second.

5. The method of claim 1, wherein the exchanging step is performed between a mobile device and a network node in a wireless network.

6. The method of claim 1, wherein the adding step assigns a non-contiguous dependency value from any previously added dependency values to collections.

7. A mobile device adapted for of collections of data for synchronization over a wireless network, each collection having an existing priority level, characterized by:

means for adding, to each collection, a dependency field having a dependency value; and

a communications system adapted to transmit, during synchronization, the priority level and dependency value for each collection.

8. The mobile device of claim 7, wherein the dependency field is eight bits.

9. The mobile device of claim 7, wherein the communications system transmits the priority level and dependency value in a initialization packet.

10. The mobile device of claim 7 wherein the means for adding is further adapted to assign a non-contiguous dependency value from any previously added dependency values to collections.
