Method of automatically replicating data objects between a mobile device and a server
First Claim
1. Method of automatically replicating data objects between a mobile device and a server, connected together via a wireless network, in which the timing of data replication across the network is determined by a network operator applying parameters that make efficient usage of network bandwidth;
- comprising;
creating a change log that lists all objects at the device and/or server to be replicated;
applying, via said network operator, as a first of said parameters, a single weight associated with each object that defines how urgently that object needs to be replicated; and
applying, via said network operator, as a second of said parameters, a threshold that is a function of time, with the single weight of each object being locally compared to the threshold at a given time and the outcome of the comparison determining whether the object is sent for replication or not at that time;
wherein all criteria that are relevant to how urgently an object needs to be replicated are represented by the single weight associated with that object.

Abstract
Network operators can control how data replication services use available bandwidth, in order to make the most efficient usage of that bandwidth, using parameters applied to a data object to be replicated. The parameters may be both time dependent and also relate to how urgently that object needs to be replicated. A change log lists all objects at the device and/or server to be replicated and the parameters then comprise a weight associated with each object that defines how urgently that object needs to be replicated; the weight of each object is then locally compared to a threshold at a given time and the outcome of the comparison determines whether the object is sent for replication or not at that time. This combination of weight and threshold gives a flexible way to control the timing of data replication and hence make the best use of bandwidth.
