Publication number: 20160061957Abstract: Examples are provided that enable a cellular network location assist to confirm a position determined using a sensor of a mobile device. As a result of global positioning system signals becoming unavailable due to the mobile device traveling indoors, the mobile device implements a sensor-based position determination that provides a position of the mobile device as the mobile device travels about a location. In order to confirm the reliability of the sensor-based position determination, the mobile device, after passage of time or after traveling some estimated distance, requests location assistance indications from the cellular network. A processor of the mobile device receives the location assistance indications and generates a directional vector based on several of the location assistance indications. Using the directional vector, the processor confirms the reliability of the dead reckoning position.Type: ApplicationFiled: August 26, 2014Publication date: March 3, 2016Inventors: Yuk Lun Li, Xin Ren, Zheng Zhao, Nanjun Qian

Patent number: 8943204Abstract: Information is provided to a mobile device while reducing the number of traffic channels established over a predetermined time period. A pull client on a mobile device receives requests for information from applications on the mobile device. The pull client creates a timing list which includes the timing requirements for each application. Applications that have overlapping timing requirements are grouped together into the same timing group. Once the time for creating a traffic channel for one of the groups arrives, a traffic channel is created between the mobile device and a carrier gateway. Information for each respective application within the same timing group is obtained through the network using the same traffic channel. When the requested information is provided to all applications within the same timing group, the traffic channel is released after a predetermined time. The method is repeated for a next timing group entry.Type: GrantFiled: January 23, 2012Date of Patent: January 27, 2015Assignee: Cellco PartnershipInventors: Mauricio Pati Caldeira de Andrada, Xin Ren, Anthony Dennis
