Systems and methods for virtually synchronizing unsynchronized or loosely synchronized networks for position location determination

摘要

Methods of operating a position network center, which includes at least one server, may include receiving timing-error data corresponding to a plurality of unsynchronized or loosely synchronized transmitters from at least one position network receiver. Moreover, the methods may include transmitting data indicating a plurality of timing errors by the plurality of unsynchronized or loosely synchronized transmitters to a wireless user device that receives signals from the plurality of unsynchronized or loosely synchronized transmitters. Related position network centers, position network receivers, and wireless user devices are also described.

1. A method of operating a position network center comprising at least one server, the method comprising:
receiving, at the position network center, timing-error data corresponding to a plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters, from at least one position network receiver; and transmitting, from the position network center, data that indicates a plurality of timing errors by the plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters and corresponds to a lack of synchronization between different networks, to a wireless user device that receives signals from the plurality of unsynchronized or loosely synchronized cellular or Wi-Fi transmitters, after receiving the timing-error data from the at least one position network receiver at the position network center.
