| Abstract(in English) | Cellular equipment gets high-performance, and smartphone gets attention in customizations to add-on native code applications like a PC. Unlike cell phone, it is difficult to avoid threats of compromising smartphone. We use multiple-OS technology to combine open environment like smartphone and secure environment like cell phone. As a result of comparison of several technologies in terms of performance, development cost and power consumption, we select OS Switching that uses Suspend/Resume function. This has a restriction that whenever an OS executed, any other OSes are suspended. Suspend OS cannot receive any mails and phone calls. Cellular equipment must be able to receive mails and phone calls to redirect them from application in executing OS to application in suspend OS by using Inter-OS Communication. However, existing Inter-OS communication method is not suitable for OS switching. Therefore, we propose an Inter-OS communication method to cooperate with application programs in OS Switching. As a result of experimentation, our method is not suitable interactive communication, but suitable for a small mount of data communication without switching OS to notificate incoming mails. |
