    • Intelligently caching global positioning system (GPS) location information from GPS satellites based on cellular radio signal strength received at a portable device. The GPS satellites broadcasts signals to the portable device and the cellular radio signal strength is at a first level indicative of a low GPS reception strength. A second level, at the portable device, of the cellular radio signal strength is detected, and the second level is indicative of an increase in GPS reception strength. GPS location information is speculatively read from the GPS satellites associated with the portable device in response to the detected second level and the increase of the GPS reception strength. The GPS location information is cached on the portable device such that the GPS location information is available to the portable device when the first level of the cellular radio signal strength is less than the second level.
    • 基于在便携式设备处接收到的蜂窝无线电信号强度,从GPS卫星智能缓存全球定位系统(GPS)位置信息。 GPS卫星向便携式设备广播信号,并且蜂窝无线电信号强度处于表示低GPS接收强度的第一级。 在便携式设备处检测蜂窝无线电信号强度的第二级,并且第二级指示GPS接收强度的增加。 响应于检测到的第二级别和GPS接收强度的增加,从与便携式设备相关联的GPS卫星推测性地读取GPS位置信息。 GPS位置信息被缓存在便携式设备上,使得当蜂窝无线电信号强度的第一级小于第二级时,GPS位置信息可用于便携式设备。
