Design And Implementation Of Mobile Device Software

With the rapid development of Information Technology(IT), mobile communication terminal unit is becoming more and more important for every country. The main research object of this paper is GSM mobile terminal unit software, i.e. mobile telephone software. Based on the studying of the whole architecture of the handset system, the thesis analyzes the whole structure or the Application Layer, and with the blocking design architecture, the block interfaces which connect MMI(man machine interface) and other blocks are provided; then the paper bring forward a kind of new running mechanism-MCCs which is beneficial to re-develop, on the basic of it, the MMI design is completed. Then, the paper provides how to realize LCD display, the icon display and animation display which are the most important parts of LCD display are designed and completed. Smart Charge, as a important part of mobile telephone software, is also one design object of the paper, the realization of Li-Ion battery charge is provided. Some of the work has been used in a certain style handset, which will come into market soon. At last, the GSM protocol which is the main body of handset protocol architecture is analyzed and designed too, which is a kind of preparatory researching.
