Title: Oscillator calibration
Inventor: MULLEN SEAN
IPC: H04L69/40
Filed: 2007-11-23
Granted: 2012-09-19
Abstract: A basestation for a cellular communication system has an interface, for connection to a computer network, and also includes an oscillator, for generating wireless transmit and receive frequencies. A controller receives timestamped response messages from a time server over the computer network, each response message being subject to a network propagation delay, which is a sum of a minimum network propagation delay and a jitter component. For each received response message an apparent network propagation delay is determined as a function of a difference between a first timestamp applied by the time server and a second timestamp based on a clock derived from said oscillator. A subset of the received response messages are selected, whose network propagation delays include minimal jitter components. The frequency accuracy of the oscillator is then determined based on changes over time in the apparent network propagation delays of the selected received response messages. The oscillator can then be adjusted based on this frequency accuracy.
