Patent number: 8229425Abstract: In a Wireless Local Area Network (WLAN), roaming from one access point to another by a mobile station without interruption to network service may be facilitated by frequently performing background scans to find neighboring access points while the mobile station is associated to the WLAN. Frequent background scanning, however, depletes battery life. By dynamically adjusting the background scanning interval during the mobile station's association to the WLAN, the mobile station's immediate need for network connectivity performance may be met, while simultaneously prolonging battery life. For example, by using a shorter background scanning interval during a telephone conversation, network connectivity performance may be maintained throughout the call. Longer background scanning intervals may be used during periods when interruptions to network connectivity may be better tolerated.Type: GrantFiled: June 29, 2010Date of Patent: July 24, 2012Assignee: Research In Motion LimitedInventor: Leonardo Salomone

Patent number: 8140095Abstract: A system comprises a receiver and a transmitter in wireless communication with the receiver. The receiver receives from the transmitter multiple bursts of data on a paging channel. First and second bursts of data comprise channel protocol information and paging mode data. The second burst comprises an encoding dependency that groups paging mode data independently of channel protocol information.Type: GrantFiled: December 4, 2008Date of Patent: March 20, 2012Assignee: Texas Instruments IncorporatedInventors: Francois R. D. Goeusse, Francois Mazard

Patent number: 8135331Abstract: A system for mobile devices that facilitates the creation and dissemination of user interest surveys to a plurality of mobile devices and PCs/laptops that comprise a user interest survey client component. A computer or PC comprising an user interest survey generator is used to generate audio assisted user interest surveys and communicate it to a distribution server for dissemination. Recipient devices, such as PCs and Mobile devices comprise an user interest survey client component to receive and present user interest survey to a user, gather user interest information, and to send it back to the distribution server or an alternate destination.Type: GrantFiled: June 25, 2007Date of Patent: March 13, 2012Inventor: Bindu Rama Rao

Patent number: 8131303Abstract: Embodiments provide a wireless network with several access points connected to a communication infrastructure. Residential or business customers of the Internet are provided an Internet interface (e.g., a digital subscriber line (DSL) modem) having a wireless transceiver. Two or more users may access the Internet or other network through the Internet interface. Each user can be assigned a unique Service Set-Identifier (SSID) with each SSID associated with a type of service (e.g., user video service, backhaul service, etc.). The amount of bandwidth assigned to the type of service (and user) may be governed by the equipment according to the assigned SSID.Type: GrantFiled: January 22, 2009Date of Patent: March 6, 2012Assignee: Qwest Communications International Inc.Inventors: Charles I. Cook, Thomas Schwengler

Patent number: 8131306Abstract: Embodiments of a wireless access network and method for allocation time and frequency resources are generally described herein. Other embodiments may be described and claimed. In some embodiments, a base station allocates contiguous groups of data subcarriers of a downlink subframe to closed-loop user stations, and allocates the remaining data subcarriers of the downlink subframe to open-loop user stations to increase frequency diversity.Type: GrantFiled: March 16, 2007Date of Patent: March 6, 2012Assignee: Intel CorporationInventors: Minnie Ho, Qinghua Li, Xintian E Lin, Vallabhajosyula S. Somayazulu, Shilpa Talwar

Patent number: 8125961Abstract: Systems and methodologies are described that facilitate enabling communication over a time varying channel with time varying interference. According to various aspects, systems and methods are described that facilitate selecting appropriate channels and identifying rates that yield optimal capacity for the selected channels. Such systems and/or methods can evaluate a signal to interference noise ratio (SINR) at a receiving node within a multinode network to facilitate selecting the rates.Type: GrantFiled: March 28, 2006Date of Patent: February 28, 2012Assignee: QUALCOMM IncorporatedInventors: Avneesh Agrawal, David Jonathan Julian, Rajat Prakash

Patent number: 8121602Abstract: A cell reselection method in a wireless communication system is described. A method of performing cell reselection based on priorities by a user equipment (UE) in a wireless communication system includes selecting one or more candidate cells satisfying a first criterion associated with priorities among a serving cell and neighbor cells, and camping on a cell satisfying a second criterion for cell reselection among the one or more candidate cells.Type: GrantFiled: October 30, 2008Date of Patent: February 21, 2012Assignee: LG Electronics Inc.Inventors: Seung June Yi, Young Dae Lee, Sung Duck Chun, Sung Jun Park, Seon Don Lee

Patent number: 8121594Abstract: The present invention provides a method for providing roaming services to one or more subscribers, correspondingly associated with the one or more HPMNs, while the one or more subscribers are registered with the VPMN. The method includes allocating a pool of GTs to a Gateway Location Register (GLR) that is associated with the VPMN, where the pool of Global Titles (GTs) corresponds to at least one of: one or more VLRs associated with the VPMN, one or more SGSNs associated with the VPMN, one or more HPMNs, and one or more HLRs associated with an HPMN from the one or more HPMNs. The method further includes facilitating mobile communication of the one or more subscribers in the VPMN using the allocated pool of GTs.Type: GrantFiled: November 5, 2007Date of Patent: February 21, 2012Assignee: Roamware, Inc.Inventor: John Yue Jun Jiang

Patent number: 8121084Abstract: A transmission area is specified flexibly in accordance with the contents of a flow. An area identification number (SHOG) is specified for each interlaced stream of wireless base stations. The same flow is sent at the same timing (or substantially at the same timing) in the interlaced stream specified for the same SHOG. A wireless terminal determines a neighbor sector or a neighbor wireless base station sending the same flow, in accordance with information given from the wireless base stations, and receives and combines the flows.Type: GrantFiled: April 20, 2010Date of Patent: February 21, 2012Assignee: Hitachi, Ltd.Inventors: Akihiko Yoshida, Shiro Mazawa, Yosuke Takahashi, Daigo Takayanagi

Patent number: 8121637Abstract: A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.Type: GrantFiled: October 15, 2010Date of Patent: February 21, 2012Assignee: Research In Motion LimitedInventors: Wen Zhao, Shahid R. Chaudry, T. L. Trevor Plestid, Hao Xue, Grace T. Y. Yeung, Clifford W. Yanoshewski
