METHODS AND APPARATUS FOR PROVIDING LOCATION DATA WITH VARIABLE VALIDITY AND QUALITY
摘要
Methods, systems and computer program products for determining a location of a device based on location information are described. In some implementations, location assist information may be requested so as to determine a location of sufficient quality to satisfy a requesting application. Upon receiving the location assist information, empherides from one or more visible sources may be requested. The location assist information may be used to determine the location of the device until the device has received and decoded the empherides.
