Abstract: 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.

Abstract translation: 提供了使蜂窝网络位置有助于确认使用移动设备的传感器确定的位置的示例。 由于全球定位系统信号由于移动设备在室内行驶而变得不可用，所以移动设备实现基于传感器的位置确定，当移动设备在某个位置上行进时提供移动设备的位置。 为了确认基于传感器的位置确定的可靠性，移动设备在经过时间之后或在旅行一些估计距离之后，请求来自蜂窝网络的定位辅助指示。 移动设备的处理器接收位置辅助指示，并且基于几个位置辅助指示产生方向矢量。 使用方向矢量，处理器确认了推算位置的可靠性。
