Abstract: Disclosed are a simulation hardware button operation method and a touch screen terminal. In the touch screen terminal, the network node of at least one pixel in the upper boundary region of a touch screen is arranged on the inner side surface of the terminal housing outside of the touch screen, and when a detection reporting unit detects a touch sensing unit sensing through the network node an user operating the touch button of the terminal, the detection reporting unit reports the corresponding pixel information of the sensed network node; an operation confirmation unit confirms the function of the operation to the touch button by the user according to the report of the detection reporting unit. Thus the location of the simulation hardware button of the touch screen terminal can be flexibly arranged at any location on the housing of the terminal outside of the touch screen.

Abstract: Embodiments of the present invention provide a method and an apparatus for generating a FOTA upgrade package, a software upgrade method, and a mobile terminal. The method for generating a FOTA upgrade package includes: generating transition software according to comparison of file names and file binary formats of software of two to-be-upgraded versions among at least two to-be-upgraded versions; and generating a FOTA upgrade package according to comparison of file names and file binary formats between the transition software and final-version software. Using the foregoing technical solutions, a software version provider may use a same FOTA upgrade package to upgrade a plurality of early versions, which meets a requirement of upgrading a plurality of early versions of different mobile users to a latest version by using a same FOTA upgrade package, and reduces development and maintenance costs for the software version provider at the same time.
