Abstract: A method is provided for prioritizing rule creation for computer-assisted customer care. When a question from a user of a device is received by a customer care analytics engine for which no rule is automatically fired, the question and a related device profile of the device are added to an unfired questions list. The analytics engine parses the question to match terms in other questions in the list. The question is also added to an appropriate category in the list based on the device profile. A prioritization algorithm is used to rank the question among other questions within the list or the category, ranking the question more highly according to the frequency of those terms in the category or the list. According to its rank-wise order, the question is directed for creation of a rule to permit automatic handling of questions having the same or similar terms in the future.

Abstract: A computer-implemented method is provided for providing customer care to a user of an electronic device. After a device profile of the electronic device is received, together with any text added by the user in a query, a customer care case is created with the received parameters from the device profile and the added text from the user. This customer care case is then automatically routed to an appropriate resource or customer care agent channel based on analysis of the parameters and the added text. A separate but related method also relates to the database of expertise and availability parameters that is maintained for a plurality of customer care agents. The database is used for the aforementioned analysis and routing.

Abstract: A method is provided for self-care based customer care for users of devices. A device agent is provided for the device. The device agent is executable on the device and is programmed for gathering information from the device in the form of a device profile and running a diagnosis of the device. The diagnosis process refers to a set of rules stored locally on the device, and aspects of the device profile are reviewed against conditions in these rules. The profile gathering and diagnosis steps are programmed to be triggered and occur on the device.

Abstract: A method is provided for delivering customer care to a user of a mobile device. A first device profile of the mobile device is collected. Based on aspects of this first device profile displayed on a customer care interface, and a problem report, a fix is provided to the mobile device with respect to the problem report. After the fix, a second device profile is collected. The system determines at least one difference between the first device profile and the second device profile. This difference is used to automatically generate a proto-rule for future fixes based on the problem report. In this way, automatic rule-making is possible. An editor is also provided so that the proto-rule can be edited.

Abstract: Circuitry and method for providing a signal indicative of instances of conduction of average inductor current in a DC-to-DC voltage converter. Such signal identifies a time when the instantaneous average current being conducted by the inductor in a DC-to-DC voltage converter can be measured by providing a signal edge approximately halfway through one of the increasing and decreasing current conduction intervals of the inductor.

Abstract: The present invention makes it possible to obtain debug- and other diagnostic information from mobile electronic devices in a system operator network. A Log Management object provides support for logging diagnostic data. A log file is employed to collect information on various device features for which tracing or debugging is turned on in a mobile electronic device such as, for example, a mobile handset, cellular phone, a personal digital assistant, a pager and a personal computer. It is also used to selectively collect information on specific events that are monitored, device specific data being collected, and network performance data, among other items. The diagnostic agent in the mobile device is a client side application that may run on the mobile device when required, or continuously as a monitoring application, and which manages and collects tracing information wirelessly to a server using a cellular data network.
