Patent number: 8452281Abstract: 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 25, 2012Date of Patent: May 28, 2013Assignee: Research In Motion LimitedInventor: Leonardo José Silva Salomone

Patent number: 8432858Abstract: To provide a technique of making it possible to shorten a time taken by channel switching. Further, to provide a technique of enabling simplification of a channel switching procedure. A radio network controller for assigning, to each wireless terminal connected to a wireless network, one of an individual channel exclusively used by the wireless terminal and a common channel shared with at least one wireless terminal different from the wireless terminal as a communication channel, includes: a determination portion for determining that an individual channel is to be assigned to a wireless terminal; and an assignment portion for, when the assignment of the individual channel has been determined, assigning an individual channel resource secured and held before the determination to the wireless terminal.Type: GrantFiled: July 26, 2006Date of Patent: April 30, 2013Assignee: Fujitsu LimitedInventors: Kazunari Kobayashi, Tomonori Kumagai, Daisuke Nitta, Hajime Hasegawa

Patent number: 8428023Abstract: A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes receiving a plurality of packets that collectively includes video data from a group of pictures comprising a sequence of video frames, wherein the sequence includes one Intra frame at the beginning of the group of pictures followed by a plurality of Predictive frames. For each packet, the packet processing function: determines the corresponding frame that includes the video data; applies a bearer selection process to select one of multiple bearers for transporting the packet over an access network, wherein each bearer has a different quality of service level which influences the probability of the transported packets being dropped, wherein the bearer selection process is based on the position of the frame within the sequence of frames; and provides, to an access network entity, an indication of the selected bearer.Type: GrantFiled: October 22, 2010Date of Patent: April 23, 2013Assignee: Motorola Solutions, Inc.Inventors: Tyrone D. Bekiares, Trent J. Miller, Steven D. Tine

Patent number: 8429515Abstract: An apparatus and a method for transmitting and receiving control information in a Multiple Input Multiple Output (MIMO) system are provided. A method of a base station for transmitting control information to a terminal in the MIMO system includes transmitting first control information for every transmission mode except for a Multiple-User (MU)-MIMO mode, to the terminal over a control channel of a subframe, and transmitting second control information for the MU-MIMO mode to the terminal over a data channel of the subframe.Type: GrantFiled: April 28, 2011Date of Patent: April 23, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-Su Han, Hi-Chan Moon, Jun-Sung Lim, Seong-Woo Ahn

Patent number: 8427983Abstract: Techniques are described for permitting uplink feedback for downlink transmission over downlink-only RF carriers to occur using uplink control channels belonging to another fully-configured RF carrier herein known as a primary carrier. Uplink feedback channels can be allocated for the downlink-only RF carriers in the uplink control regions of a fully-configured RF carrier immediately following the uplink control channels for the primary carrier are allocated. The uplink feedback channels for downlink-only RF carriers can be allocated based on global or local index number of each downlink-only RF carrier in sequential order based on ascending or descending sorting of the index numbers.Type: GrantFiled: October 12, 2010Date of Patent: April 23, 2013Assignee: Intel CorporationInventors: Sassan Ahmadi, Shahrnaz Azizi

Patent number: 8423055Abstract: A method of using an intercom on a cordless telephone during an active call. The active call is put on hold while the intercom is in use. Once the call is re-activated, the intercom is shut off. This system may be designed for a cordless telephone with one handset or a plurality of handsets.Type: GrantFiled: February 7, 2012Date of Patent: April 16, 2013Assignee: Agere Systems LLCInventors: Joseph M. Cannon, James A. Johanson

Patent number: 8423066Abstract: A method, wireless communication device, and computer program product are provided for scheduling wireless communication between a base station and one or more mobile wireless communication devices. Signals indicative of motion are obtained and utilized to facilitate scheduling operations. In some embodiments, signals indicative of motion are used in estimation or prediction of variable conditions of the common radio medium, and scheduling, such as opportunistic scheduling, is performed based at least in part on the estimates or predictions. Signals indicative of motion may be obtained from GPS data, accelerometer data or other data generated at a mobile wireless communication device.Type: GrantFiled: February 23, 2010Date of Patent: April 16, 2013Assignee: Research In Motion LimitedInventor: Michael Joseph DeLuca
