Method and apparatus for updating frame number
First Claim
1. A method for maintaining and broadcasting frame numbers in a digital system, the digital system monitoring a frame number controller through a central controlling unit to broadcast a new frame number of a next data frame, the method comprising the steps of:
- the frame number controller obtaining the new frame number during a transmission period of a current data frame;
broadcasting information related to the new frame number to frame number receivers installed in operational components of the digital system; and
generating a frame boundary signal when each frame number receiver completely receives the new frame number, so the corresponding operational component can start using the new frame number.

Abstract
A method and system thereof for maintaining and broadcasting frame numbers in a digital communication system. The system monitors a frame number controller through a central controlling unit. The frame number controller maintains the frame numbers required by the system, as well as broadcasts the frame number for the subsequent data frame to each frame number receiver in the operational components. Each frame number receiver generates a frame boundary signal when a complete frame number is received from the frame number controller, and notifies the corresponding operational component to start using the frame number just received. The operational component can also determine if unfinished work according to the frame boundary signal exists, and report the error to the system. The aim is to provide a simple mechanism to maintain the synchronization of the system, and utilizes the serial port to transmit information related to the new frame number.

11. A system for maintaining and broadcasting frame numbers in a digital system, comprising:
-
a central controlling unit for monitoring the frame numbers used in the digital system;
a frame number controller controlled by the central controlling unit, obtaining a new frame number corresponding to a next data frame during a transmission period of a current data frame, and broadcasting information related to the new frame number; and
a frame number receiver installed in each operational component of the digital system, for receiving the information related to the new frame number, and generating a frame boundary signal when the new frame number is completely received, so the corresponding operational component can start using the new frame number. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
