Patent number: 8103301Abstract: A wireless device configured to support a wireless networking protocol may utilize signal processing techniques that can mitigate the effects of jammer signals. For example, when a measured power associated with a digital sample of a received wireless signal is greater than a threshold, the wireless device may determine if the wireless signal corresponds to a wireless networking packet to be demodulated. If the wireless signal does not correspond to a wireless networking packet to be demodulated, the wireless device may adjust the threshold so that the power associated with the digital sample is less than the threshold. In other words, if the signal is a jammer signal, the wireless device may adjust its noise floor upward so that continuous reception of the same jammer signal does not trigger demodulation a second time.Type: GrantFiled: April 11, 2003Date of Patent: January 24, 2012Assignee: QUALCOMM, IncorporatedInventors: Daniel F.

Patent number: 8045974Abstract: A method for establishing an optimized communication link between mobile network nodes. An interface management module of a first mobile network node checks the mobile network node for available network interfaces and establishes a look-up table with the available network interfaces. Based on the look-up table at least one signalling channel is set up for configuration data with communication parameters and/or security parameters via one of the available network interfaces with a second mobile network node. Based on the look-up table with the communication parameters and the security parameters at least one data channel is established between the first mobile network node and the second mobile network node. Both the at least one signalling channel and the at least one data channel are able to be set up via one or more network interfaces.Type: GrantFiled: August 17, 2004Date of Patent: October 25, 2011Assignee: Swisscom AGInventors: Marc Danzeisen, Michael Schaedler, Daniel Rodellar

Publication number: 20110256863Abstract: Generating a radio frequency test signal for a mobile wireless communication device from a set of scanned radio frequency data that represents a plurality of radio frequency channels over a sequence of time intervals. A segment of the set of scanned radio frequency data over a time interval is classified into one of several radio frequency environments. A subset of the segment of scanned radio frequency data is selected based on the classified radio frequency environment. A segment of the radio frequency test signal is generated using the selected subset of scanned radio frequency data. The steps of classifying, selecting and generating are repeated for each time interval in the sequence of time intervals. Classifying the segment of scanned radio frequency data into a radio frequency environment includes comparing a set of statistics extracted from the segment of scanned radio frequency data to pre-defined classification ranges.Type: ApplicationFiled: April 15, 2010Publication date: October 20, 2011Applicant: APPLE INC.Inventors: Venkatasubramanian Ramasamy, Srinivasan Vasudevan

Publication number: 20110250883Abstract: A network monitoring system includes data source routers, data servers, and user interface modules for depicting visual data presentations that show call activity within a satellite-based communication network. The data source routers capture signaling data from a terrestrial portion of the network and supply the signaling data to the data servers. The user interface modules request selected data from the data servers based on selected display filtering settings and generate the visual data presentations, including a geo view, a satellite activity grid, and a message view. The geo view shows a time progression of live or recorded call activity data on a map. The satellite activity grid organizes a time-progression of live or recorded call activity on a two-dimensional grid representing each satellite spot beam in the system. The message view shows a detailed listing of individual messages that have occurred within selected call flows in the network.Type: ApplicationFiled: April 8, 2010Publication date: October 13, 2011Applicant: ITT MANUFACTURING ENTERPRISES, INC.Inventors: Christopher D.

Patent number: 8032132Abstract: Several system diagnostic and network management tools are disclosed that, as a primary goal, support the consumer's ability to self diagnose and solve an existing problem. A non-intrusive diagnostic tool is provided that exposes system parameters of a consumer system for remote analysis by qualified personnel. Important data parameters of a given radio receiver are preferably predetermined and gathered directly at the receiver. Then, they are uploaded via the Internet from a removable memory placed into an Internet terminal (e.g., PC), or through a temporary docking station connected to an Internet terminal. This leads toward quick and efficient problem resolution with a properly informed customer service representative that is crucial to enriching the consumer's experience. The data collected relating to relevant system parameters may be used by service providers to enhance or even in some cases enable services.Type: GrantFiled: September 21, 2004Date of Patent: October 4, 2011Assignee: Agere Systems Inc.Inventors: Roger A.

Publication number: 20110223906Abstract: In a cellular wireless system, power thresholds used for determining whether or not to add or drop servers held in a set of servers, such as an active set, for serving a user equipment are determined on the basis of the motion of the respective user equipment. A lower threshold may be used with respect to the adding or dropping of a given server to or from a set of servers for serving a fast moving user equipment than would be used for the same server with respect to its adding or dropping to or from a set of servers for serving a slow moving user equipment, while maintaining a given quality of service. As a result, the average number of servers held in sets is reduced in a typical network that comprises a plurality of user equipments moving at different speeds, compared to a situation in which the threshold is set irrespective of the motion of a user equipment.Type: ApplicationFiled: May 25, 2011Publication date: September 15, 2011Applicant: NORTEL NETWORKS LIMITEDInventors: Steven Hall, Steven Baines, David Bevan, Andrew Jeffries
