Abstract: Content is automatically provided to a mobile web browsing device from a web server, by the following process: (a) receiving at a computer, remotely connected to the device, a log of data identifying content that has been viewed by the device; (b) automatically sending updated content stored on the web server to the device; (c) causing that updated content to be automatically stored in device memory. Because user activity is replicated back from the device to the remote computer, the content cached on a given device can be completely optimised for the user of that device and no-one else.

Abstract: A mobile telephone can be configured to interact with external services by using a client application on the telephone that interacts with several external services via an intermediary server. The server sends, to the mobile telephone, configuration information to enable or disable defined sets of functionality in the application, the configuration information depending on and appropriate to the particular external service selected on the mobile telephone and being sent automatically to the mobile telephone over-the-air. An implementation of the invention enables a single client application on the mobile telephone to automatically configure features on / off, and modify the terminology used in resources (such as menus, text strings, bitmap images, sounds, sonic effects etc.) depending on the external system or service that the client is connected to via the intermediary server.

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.

Abstract: A wireless information device automatically replicates data held on the device to a remote server over a wireless network. An application on the device (a) automatically determines the battery level of the device; (b) prevents sending data over the wireless network if the battery level is below a first threshold.

Abstract: Where a first computing device is given responsibility for determining whether data that is time stamped by a second computing device is replicated or not, then the first device can compare a time stamp from the second device against a time signal from its own internal clock to determine a delta and use that delta to deduce the correct delta to apply to time stamps associated with later data from the second computing device.
