SYSTEM AND METHOD FOR OBTAINING LOCATION ASSISTANCE DATA |
摘要 |
<p>An electronic device such as a cellular telephone, for example, includes a receiver that receives broadcast radio signals transmitted by a commercial broadcast radio station. The broadcast radio signals include information that identifies a location of the radio station, an antenna associated with the radio station, or the radio station. The device also includes positioning circuitry to allow the device to determine its current location. A controller in the device extracts the information identifying the radio station from the received broadcast signal, and acquires one or more satellites of a navigational system based on the information.</p> |
