Patent number: 9118408Abstract: Methods and apparatus for improving operational and/or cost performance based on filter characteristics. Existing schemes for measuring filter performance are based on a worst case filter performance across a range of frequencies and temperature. Filter performance can be more accurately characterized over one or more frequency ranges. In one exemplary embodiment the frequency is characterized according to a functional (e.g., linear-average) metric. By providing more accurate representation of the reception/transmission filter performance, both network and device optimizations can aggressively manage available power and handle smaller (tighter) margins.Type: GrantFiled: September 27, 2012Date of Patent: August 25, 2015Assignee: APPLE INC.Inventor: Dawei Zhang

Patent number: 9104807Abstract: Systems and methods for providing symbolic information about fields, methods, and/or classes for a target device. A system and method may be used where the runtime processing is split between a host system and a target system. At the target device a test program uses a symbol not defined on the target device. A query is sent from the target device to a symbolic information source. The symbolic information source then provides the target device with information about the undefined symbol. The target device uses the information from the symbolic information source to complete the test program.Type: GrantFiled: August 11, 2014Date of Patent: August 11, 2015Assignee: BlackBerry LimitedInventors: John Fredric Arthur Dahms, Stephen Woodward, David Howes

Patent number: 9077507Abstract: A method and system provide a plurality of femto cells that are deployed within a macro cell of cellular network. The femto cells improve cellular service inside structures, such as residential and commercial structures. Femto base stations convert signals between an airlink-interface and core network to enable data communication between the mobile terminal and an access network to occur through the Internet and a public switched telephone network. The femto base stations are independent of each other and the macro cell. The method and system provide the femto base stations with interference awareness and mitigation techniques to minimize interference with the cellular network.Type: GrantFiled: June 25, 2014Date of Patent: July 7, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Miroslav Budic, Jeffrey Wade Scott

Patent number: RE45671Abstract: A converged IP messaging client transmits a session establishment request for interactive message communication. When a converged IP messaging server receives the request, it determines whether a target client of the interactive message communication uses a converged IP messaging service. If not, the converged IP messaging server transmits the session establishment request to an IWF. If it is determined that the target client is an SM client, the IWF generates an interactive message communication request by transforming a format of the session establishment request into an SMS format and transmits the interactive message communication request to the SM client. If the IWF receives an acceptance response from the SM client in response to the interactive message communication request within an effective response time, a session for the interactive message communication can be established between the converged IP messaging client and the SM client.Type: GrantFiled: February 26, 2013Date of Patent: September 15, 2015Assignee: Samsung Electronics Co., LtdInventors: Seung-Yong Lee, Kyung-Tak Lee, Jae-Kwon Oh, Sang-Kyung Sung, Wuk Kim
