Research And Implementation Of MAC Layer Management Control Function In CNGI Mobile Terminal

In the CNGI(China's Next Generation Internet) mobile terminal , the realization of MAC layer's functions determines the mode and efficiency of terminals'accessing to the media. Meanwhile, the realization of management controlling functions determines whether the station can access to the CNGI network hierarchy normally. Therefore, the design and implementation of MAC layer's management controlling functions has a very important meaning.The thesis firstly presented important concepts of MAC protocol in detail, including the infrastructure of network construction, the model of protocol, working modes, frame formats , etc ,and also gave the protocol and management control functions which should be realized. Then it put emphasis on studying the concrete operation theories and realization methods of synchronization, scanning, joining, authentification, association, and power management in management controlling blocks. Finally, this thesis figured out the concrete realization methods, and gave out testing methods and the results.The result showed that the design and implementation of the MAC management control founctions reached the real needs and the initial design.
