In the wake of continued development in Internet and wireless communication technologies, fixed location access of the Internet has expanded into mobile access. While the cost of mobile access is sharply falling, the speed of accessing data is rapidly rising. Therefore, a broadband network has been formed and is becoming the new network infrastructure. With fewer accesssite limitations and plenty of types of access terminals, mobile Internet access with broadband adoption has a high speed, low cost, and a wide range, providing favorable support for achieving on-demand data access time for users. Therefore, mobile devices that developed based on traditional mobile communication devices are now mainstream components of the mobile Internet. This extends from basic phone capability to intelligent equipment that is able to meet the demand of processing large amounts of data. With the rapid development of the mobile Internet, users have become more and more dependent on mobile devices. Traditionally, desktop computers have been used as devices for accessing the Internet. With advances in mobile technology, mobile devices have become a bridge between users and application environments, and now, mobile access has become the primary network access. Relying on these advances, many application environments based on the Internet are quickly transferring to the mobile Internet.
