20080319940 | Message Log Analysis for System Behavior Evaluation - A technique is disclosed that enables the run-time behavior of a data-processing system to be analyzed and, in many cases, to be predicted. In particular, the illustrative embodiment of the present invention comprises i) transforming the messages that constitute an unstructured log into a numerical series and ii) applying a time-series analysis on the resultant series for the purpose of pattern detection. Indeed, it is recognized in the illustrative embodiment that the problem really is to detect patterns that depict aspects of system behavior, regardless of the textual content of the individual log messages. In other words, by analyzing the totality of the messages in the log or logs—as opposed to looking for pre-defined patterns of the individual messages—system behavior can be mapped and understood. The mapping helps in characterizing the system for the purposes of predicting failure, determining the time required to reach stability during failure recovery, and so forth. | 12-25-2008 |
20090082062 | Integrating a Cellular Phone with a Speech-Enabled Softphone - A method is disclosed that enables access to the paired combination of a personal computer and cellular telephone, the access being provided through voice commands from a Bluetooth headset or other type of wireless headset. Through the headset, a user is able to invoke a speech-recognition engine during a call in progress that involves the cell phone with which the personal computer has been paired. The set of phrases that can be recognized by the engine, which is resident at the personal computer, are based on the current call-processing state of the call that is being handled by the paired cell phone. Some of the phrases correspond to commands to retrieve one or more entries from a database, such as one stored at the cell phone. One or more of the commands can be for controlling the cell phone or a softphone application that executes at the personal computer. | 03-26-2009 |
20090285123 | Method and apparatus for content-based routing and filtering at routers using channels - Channels between routers for use in packet routing via payload inspection. The channels constitute logical connections between routers and include subjects and attributes. Publishers create channels for routing particular types of content as defined by the subjects and attributes. The publishers also create proxies and notifications on the channels. The channel definitions for routers identify packet or message structures so that the routers can locate attributes in the packets for content-based routing. The routers apply the packet attributes to filters encapsulating subscriptions in order to perform the content-based routing in the network core. The routers also locally cache content, providing distributed caching of content throughout the network core. | 11-19-2009 |
20100056111 | Automated Retrieval and Handling of a Second Telecommunications Terminal's Voicemail by a First Terminal - An apparatus and method are disclosed that enable a terminal such as a computer-based softphone to retrieve and handle, transparently for its user, the voicemail that has been left by calling parties who called the user's cell-phone number.

20110239120 | ON-DEMAND FEATURE SERVER ACTIVATION IN THE CLOUD - A feature activation system provides a mixed computing environment that includes a server and cloud computing. The hybrid model splits the execution of a communication feature between the cloud and the enterprise server installed at or with the enterprise. Service activation is linked to a portal that can communicate with either an intermediary system or directly with an entity executing computer programs in the cloud. When the customer desires to use a feature, the customer accesses the portal and activates the feature the enterprise desires. In the background, the portal instantiates a virtual machine, on any cloud platform, and then installs the feature with virtual machine on that cloud server. To execute feature, the enterprise server and the virtual machine exchange information between the server and the cloud and allow the feature to access the enterprise server or enterprise data. When the user has completed feature execution, the instance of the feature may be stopped and discarded and any data may be saved either at the enterprise or within the cloud. | 09-29-2011 |
