Abstract: A messaging architecture is disclosed which enables a single messaging application, handling non-transport specific attributes and operations, to manipulate any commonly known message type (such as fax, e-mail, pager, SMS, voice mail) using dynamically loadable plug-ins which contribute the ability to handle all transport specific attributes and operations. This architecture results in a single in-box being presented to a user for browsing all incoming messages, irrespective of message type.

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 over a wireless network, 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 over the wireless network; (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: 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: 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.
