  • Publication number: 20070207800
    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.
