First Claim
1. A wireless mobile communication device, comprising:
- a communication receiver in the wireless mobile communication device;
a positioning system receiver in the wireless mobile communication device;
an absolute time signal received at the positioning system receiver of the wireless mobile communication device;
a network time signal received at the communication receiver of the wireless mobile communication device;
a controller in signal communication with the position system receiver and the communication receiver, where the controller is configured to determine an offset of the absolute time signal from the network time signal;
a memory that stores the offset of the absolute time signal from the network time signal; and
a transmitter in the wireless mobile communication device that transmits the offset for receipt by another wireless mobile communication device.

Abstract
A wireless communications device comprises a communication receiver and a positioning system receiver in the wireless mobile communication device. An absolute time signal is received at the positioning system. A network time signal is received at the communication receiver of the wireless mobile communication device. A controller is in signal communication with the position system receiver and the communication receiver. The controller is configured to determine an offset of the absolute time signal from the network time signal and generates a timing mark. The timing mark is tagged by the positioning system receiver with an internal clock value wherein the timing mark has a known relationship with the absolute time signal. A memory stores the offset of the absolute time signal from the network time signal. A transmitter in the wireless mobile communication device transmits the offset for receipt by another wireless mobile communication device.
