Abstract:
System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperature-calibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperature-calibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device. The trigger condition can include first use or power-on, charging, presence in an outdoor environment, variation in operating temperature, pre-specified time, and/or user input pertaining to the mobile device.

Claim (Index 2):
A method of temperature-calibrating a non-temperature compensated crystal oscillator (XO) in a mobile device, the method comprising:\n determining that a temperature-calibration status of the XO is not fully temperature-calibrated; detecting a trigger condition related to temperature-calibration of the XO; and initiating a temperature-calibration session, wherein the temperature-calibration session comprises:\n receiving wireless signals based on the trigger condition; and \n temperature-calibrating the XO in a background mode based on the received wireless signals, wherein the mobile device is configured to execute position based applications or global navigation satellite systems (GNSS) based applications, and the background mode is independent from the position based applications or global navigation satellite systems (GNSS) based applications.
