Wireless Access on Next Generation Broadband Internet Services

The WiBro is a wireless Internet system toward next generation system designed to be able to provide a variety of information and multimedia contents services through high speed wireless Internet access via various user terminals. In this paper, we introduce the WiBro system and present designed logical structure of WiBro Access Terminal for the system. We propose a stable execution model preventing system failure generated by the inconsistency of the data manipulation. The model has the characteristic of eliminating the data inconsistency with accomplishing by using the delayed tasklet concept. Analytic model shows minimizing the service time for tasklet make the system stable against system failure.
