Abstract
The present invention discloses a method and system for monitoring a wireless network clock compared to an absolute time scale using the user mobile stations themselves. The major advantage is the capability to transfer GPS time to a Mobile Station in a wireless network, and thus to decrease the time necessary for the mobile receiver to perform position calculations, with minimal additional hardware required by the network.
Claims20
A method for synchronizing an unsynchronized radio network, comprising:
- determining GPS time at a mobile GPS receiver;
- comparing the determined GPS time to a second time source;
- storing an offset between the GPS time and the second time source;
- and
- using the stored offset to acquire GPS satellites.
2 more elements
A method for synchronizing an unsynchronized radio network, comprising:
- computing an offset between GPS time and a local time source;
- storing the offset;
- and
- using the stored offset at a later time to aid in the acquisition of at least one GPS satellite signal.
