With the functions of mobile phone richer and its uses wider, mobile phone software platform technology gets to be more and more important. The great effect of mobile phone software platform on its development and performance has made it a hotspot in technology. To make the construction, integration and distribution of Linux-based Embedded Software Platform easier, Platform Creation Kit is needed to improve the efficiency of mobile phone software platform. Platform Creation Kit is a graphic user interface for system integration and distribution, functional coverage of the whole process of creating mobile phone software platform. This study analyses the advantage of Linux-based mobile phone software platform, discusses software package management technology, and describes the software architecture of PCK. Finally, it discusses its important role in mobile phone software development.
