Abstract: A mobile terminal apparatus checks if a user is a proper user based on the operation of the user and, if the result of authentication is negative, uploads predetermined data, which is part of data stored in a memory, to a predetermined server. After the transmission is completed, the mobile terminal apparatus erases the uploaded data from the memory. It is also possible to instruct the mobile terminal apparatus to upload and erase data from an external source using an electronic mail or a telephone tone signal sequence. This may protect data contained in mobile terminal apparatus that has been lost, from a person who improperly attempts to access the data.

Abstract: A mobile terminal apparatus is provided in order to effectively utilizing more than one display area. At least when a specific application is executed, a mobile terminal apparatus has a first display mode which uses its screen upon dividing its main display into top and bottom display areas and a center display area, and also has a second display mode using the entire screen main display area without division. Based on a key operation as well as execution and termination of the application, the first and second display modes are switched over. In the second display mode, at least part of the contents shown on the top and bottom display areas in the first display mode are exhibited on a sub display area. For example, when under the second display mode, as the contents to be exhibited on the sub display area, the contents shown on the top and bottom display areas as well as the content shown on the sub display section are switched over or shown by scrolling.

Abstract: A task display switching method, a portable apparatus and a portable communications apparatus which, when a plurality of software applications are activated and processed in parallel, make it possible to switch a display between each of the software applications with ease. According to the task display switching method, a portable apparatus capable of processing a plurality of tasks in parallel and of displaying a plurality of display regions for displaying data, an icon associated with a task displayed on a first display region is generated automatically or manually, and the generated icon is displayed in a second display region. When any icon thus generated is selected from a plurality of icons displayed on the second display region, the task associated with the selected icon is restored and displayed in the first display region.

Abstract: An information acquisition section acquires application halfway information, user preference, updated date and time, real-timeness, usage frequency, usage history, radio wave state, remaining battery level, billing information or other information. A controller calculates recommendation values indicating recommended degrees to recommend the use to a user for each of a plurality of applications and for each of the contents of each of the applications, using the information that the information acquisition section acquired. Then, for example, when a specific button is pressed, the controller gives priorities to the plurality of applications and contents based on the recommendation values, causing the applications and contents to be displayed on a display of a display section 15 in the order of priority. Thus, of the various applications and contents, it makes it possible to select one that is more matched to the user preference and suitable for the terminal usage pattern.

Abstract: There are provided a task display switching method, a portable apparatus and a portable communications apparatus which, when a plurality of application software are activated and processed in parallel, make it possible to switch a display between each of the application software with ease. According to the task display switching method, the portable apparatus and the portable communications apparatus of the present invention, in a portable apparatus capable of processing a plurality of tasks in parallel and of displaying a plurality of display regions for displaying data, an icon associated with a task displayed on a first display region is generated automatically or manually, and the generated icon is displayed in a second display region. When any icon thus generated is selected from a plurality of icons displayed on the second display region, the task associated with the selected icon is restored and displayed in the first display region.

Abstract: Channel quality can be detected accurately in a wireless transmission system such as an HSDPA method. In the case of estimating a channel quality of a signal transmitted by a Code Division Multiple Access method and of estimating the channel quality in a system having a synchronization channel not orthogonal to a channel receiving data, a noise component of a desired channel is estimated; degree of a noise component caused by the synchronization channel is estimated with respect to the estimated noise; and a channel quality of a receiving channel is detected based on the estimated degree of the noise component.
