摘要： A speed measuring system for measuring the speed of a wireless communication terminal communicating with a base station includes an angle measuring unit, a distance measuring unit, a time measuring unit, and a speed calculator. The base station includes a signal tower and an antenna on the signal tower. The signal tower defines a central longitudinal axis perpendicular to the antenna, and the axis intersects the antenna at a point. The angle measuring unit measures an included angle between signal from the wireless communication terminal at any location and the antenna. The distance measuring unit measures a distance between the wireless communication terminal at any location and the point. The time measuring unit measures the time the wireless communication terminal takes from a first location to a second location. The speed calculator calculates the speed of the wireless communication terminal.

摘要： A communication terminal having a synchronization command to synchronize a clock of the communication terminal is provided. The communication terminal sends a short message to a service center in response to the synchronization command. The communication terminal receives a status report containing time information. The communication terminal retrieves the time information from the status report, and synchronizes the clock of the communication terminal according to the retrieved time information. Moreover, a method for synchronizing the clock of the communication terminal is provided.
