  Embodiments of a mobile terminal emulation system according to the present invention will be described below with reference to the accompanying drawings.

  In FIG. 1, a mobile terminal composed of a mobile phone 1 is held over a reader / writer provided in a PC terminal 2 (notebook personal computer in this example) such as a notebook personal computer or a desktop personal computer so that the PC terminal 2 is artificially connected to the mobile phone 1. A system configuration example of a portable terminal emulation system is shown.

  The mobile phone 1 is equipped with a well-known non-contact type IC chip 3 and an antenna 4. The non-contact type IC chip 3 includes a terminal including terminal model identification information such as a user agent and a unique ID. Unique information is stored.

  The PC terminal 2 includes an input unit 5 such as a full keyboard and a mouse, an output unit such as a monitor 6, a reader / writer 7 that performs wireless communication processing with the non-contact type IC chip 3, and a control unit 8 that controls these. At least. The control unit 8 of the PC terminal 2 includes a general-purpose operating system (general-purpose OS) 9 such as Windows (registered trademark), and is connected via a fixed communication network 10 and a mobile communication network 11. A mobile phone application program 13 for accessing the mobile phone, and an individual authentication program 15 for acquiring an individual authentication ID of the mobile phone from the authentication server for individual authentication service 14 connected via the fixed communication network 10 and the mobile communication network 11. . Further, the control unit 8 is interposed between the general-purpose operating system 9, the mobile phone application program 13 and the individual authentication program 15 to cause the PC terminal 2 to function in a pseudo manner as the mobile phone 1. Middleware (emulator) 16 for executing the application program 13 and the individual authentication program 15.

This middleware includes a linking control unit that links the PC terminal 2 and the mobile phone 1 recognized via the reader / writer 7. In this system configuration example, the unique ID of the contactless IC chip 3 mounted on the mobile phone 1 recognized through license authentication of the PC terminal 2 in which client software such as anti-virus software is installed or the reader / writer 7 is recognized. Is connected to the PC terminal 2 via the fixed communication network 10, and the PC terminal 2 authenticated here and the mobile phone 1 on which the non-contact IC chip having the unique ID is mounted. The back-end system 18 is notified via the secure server 17 of the tied information.
Reference numeral 19 denotes a terminal authentication server for authenticating a unique ID of the non-contact IC chip 3.

Next, the operation of the mobile terminal emulation system configured as described above will be described based on the flowcharts shown in FIGS.
First, the client software of the portable emulation system is installed in the PC terminal 2 in advance (step S01), and if the reader / writer is externally connected, the reader / writer 7 is connected to the PC terminal 2 (step S02). The mobile phone 1 is set in a standby state (step S03).

  In this state, as shown in FIG. 4A, when the cellular phone 1 is held over the reader / writer 7 (step S04), the PC terminal 2 confirms that the cellular phone 1 is held over the reader / writer 7. The menu selection screen shown in FIG. 4B is activated (step S05), and the presence or absence of an execution request for the emulation function is confirmed. In response to this, the user selects a selection button of the “mobile emulation” icon 20 from the menu selection screen and double-clicks to confirm the execution request of the emulation function, and the mobile emulation software is executed. Start (step S06).

  At the same time, the PC terminal 2 performs license confirmation and authentication with the secure server 17 for the PC terminal 2 into which the portable software for the mobile emulation system is installed (step S07). This license confirmation / authentication is realized by confirming the license of anti-virus software installed in the PC terminal 2 or the like.

  Thereafter, the PC terminal 2 is stored in the non-contact type IC chip 3 via the reader / writer 7 in order to recognize the mobile phone 1 on which the non-contact type IC chip 3 held over the reader / writer 7 is mounted. The terminal unique information of the mobile phone 1 including the terminal model identification information (user agent) and the unique ID of the contactless IC chip 3 is read (step S08), and client software is introduced based on the read terminal unique information. Association information (PC terminal = cell phone) for associating the license-authenticated PC terminal with the mobile phone 1 held over the reader / writer 7 is formed (step S09), and the association information is recognized by the secure server 17 (Step S10), and notifies the back-end system 18 via the secure server 17 (step S11).

  Thereafter, the back-end system 18 requests the terminal authentication server 19 to authenticate the unique ID read from the non-contact IC chip 3 of the mobile phone 1 (step S12). When the authentication of the unique ID of the non-contact type IC chip 3 is permitted (step S13), the authentication permission notification of the unique ID is notified to the secure server 17 via the back-end system 18 (step S14). From the association information, the “mobile emulation” client software is normally activated for the PC terminal 2 associated with the cellular phone 1 on which the non-contact IC chip 3 having this unique ID is mounted. Display of the top screen is permitted (step S15).

  In response to this, the PC terminal 2 displays the top screen shown in FIG. 5 on the monitor of confidence (step S16). The user sees this display, selects a desired application from the menu, and activates it (step S17).

  As a result, the selected application program is started on the middleware, and after confirming the association of “PC terminal = mobile phone”, the selected application is connected to the application site (mobile phone application server 12). (Step S18), terminal type identification information (user agent) is notified to the connected application site. For this reason, the mobile phone site is displayed on the monitor 6 of the PC terminal 2 in an operable manner with the terminal model identification information (user agent) and can be used.

  The display on the monitor 6 of the PC terminal 2 has the same display width as the display on the mobile phone on the monitor with the scroll screen to be displayed on the mobile phone 1 as shown in FIG. In addition, the image is continuously displayed in the vertical direction so that the entire image can be viewed without scrolling or scrolling as much as possible.

  Thereafter, the PC terminal 2 is connected to the individual authentication service authentication server 14 by the mobile phone individual authentication program 15 and acquires the individual authentication ID of the held mobile phone 1 in preparation for transition to the application site. (Step S19).

  As a result, when a request for transition of the screen of the mobile phone application started on the PC terminal is made together with a request for using the individual authentication ID (step S20), the individual authentication is performed from the individual authentication service authentication server 14 to the application server that is the transition destination. The ID is notified (step S21), and by permitting individual authentication in response to the screen transition request from the PC terminal 2, the screen transition is performed without inputting an ID or password separately (step S22).

  At this time, as shown in FIG. 6, the display on the monitor 6 of the PC terminal 2 displays the transitioned screen in parallel on the monitor together with the screen before the transition. That is, in this example, by selecting “Category Search” from the top screen shown in FIG. 6B, the category search screen shown in FIG. 6C is displayed so that it can be operated in parallel while leaving the top screen. Furthermore, by selecting “Chaku-Uta Full Video Clip” from the category search screen, the Chaku-Uta full video clip screen shown in FIG. 6D is displayed so that it can be operated in parallel while leaving the previous screen. Each time, a new window is opened while leaving the previous window, and each window has a scroll screen to be displayed on the mobile phone 1 with the same display width as the display on the mobile phone on the monitor, and It is displayed continuously in the vertical direction.

  The series of operations described above is performed only while the mobile phone 1 is held over the reader / writer 7. When the mobile phone 1 is moved away from the reader / writer 7, all the applications related to mobile emulation are terminated at that time. The emulation function of the PC terminal 2 ends.

  Therefore, according to the above-described configuration, simply holding the mobile phone 1 over the reader / writer 7 of the PC terminal 2, the PC terminal 2 becomes the mobile phone 1 held up (the PC terminal 2 virtually becomes the mobile phone 1). ), The PC terminal 2 can perform the same behavior as when the mobile phone 1 accesses the mobile phone site.

  In addition, since a monitor 6, a full keyboard, a mouse, and the like larger than the mobile phone 1 can be used, a multi-window that cannot be realized with a small screen of the mobile phone 1 and a continuous display that does not require repeated scrolling. It can be done, and comfortable input with a full keyboard and mouse is possible. This makes it possible to display a new screen with the past screen displayed, making it easier to grasp the history of the visited site, and to quickly switch between screens by operating the full keyboard or mouse. Can be performed.

In addition, the continuous display and the multi-window display make it possible to notice the existence of content in a deep hierarchy that has been often overlooked when using the mobile phone 1, and increase the recognition and usage frequency of the content. Is possible.
Furthermore, since the PC terminal is recognized and authenticated as a mobile phone, the mobile phone individual authentication ID is acquired and a screen transition is requested. It is possible to use the system to be used.

  In the above-described configuration, an example in which the reader / writer 7 for a non-contact type IC chip is externally attached to the PC terminal 2 is shown, but it may be built in the PC terminal 2. Moreover, although the case where the PC terminal is configured by a notebook personal computer is shown in the above configuration, the PC terminal may be a desktop personal computer.
