Description

なお、上述する各実施の形態は、本発明の好適な実施の形態であり、本発明の要旨を逸脱しない範囲内において種々変更実施が可能である。例えば、通信端末１０、通信端末２０、サーバ３０、アクセスポイント１１およびアクセスポイント２１の機能を実現するためのプログラムを各装置に読込ませて実行することにより各装置の機能を実現する処理を行ってもよい。さらに、そのプログラムは、コンピュータ読み取り可能な記録媒体であるＣＤ−ＲＯＭまたは光磁気ディスクなどを介して、または伝送媒体であるインターネット、電話回線などを介して伝送波により他のコンピュータシステムに伝送されてもよい。また、各装置の機能が他の装置によりまとめて実現されたり、追加の装置により機能が分散されて実現される形態も本発明の範囲内である。なお、３Ｇは無線ＷＡＮ（ＷｉｄｅＡｒｅａＮｅｔｗｏｒｋ）通信規格の一例であって、Ｗ−ＣＤＭＡ（Ｗｉｄｅｂａｎｄ−ＣｏｄｅＤｉｖｉｓｉｏｎＭｕｌｔｉｐｌｅＡｃｃｅｓｓ）、ＬＴＥ（ＬｏｎｇＴｅｒｍＥｖｏｌｕｔｉｏｎ）など他の無線ＷＡＮ通信規格に置き換えても同様に実施可能なことは言うまでもない。 Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, a program for realizing the functions of the communication terminal 10, the communication terminal 20, the server 30, the access point 11, and the access point 21 is loaded into each device and executed, thereby executing a process for realizing the function of each device. Also good. Further, the program is transmitted to another computer system by a transmission wave via a computer-readable recording medium such as a CD-ROM or a magneto-optical disk, or via a transmission medium such as the Internet or a telephone line. Also good. In addition, it is also within the scope of the present invention that the functions of each device are realized by other devices collectively or the functions are distributed by additional devices. Note that 3G is an example of a wireless WAN (Wide Area Network) communication standard, and can be similarly replaced with other wireless WAN communication standards such as W-CDMA (Wideband-Code Division Multiple Access) and LTE (Long Term Evolution). Needless to say, it can be implemented.
