    • In a location identifying method, the sight of users of mobile communication terminals is estimated by calculating directions of the users based on position information of the mobile communication terminals, and the location where the lines of sight of the users are concentrated is identified based on the estimated sight. By identifying a location where the lines of sight of the users of the mobile communication terminals are concentrated, it is possible to identify an installation location where high advertising effectiveness can be achieved. Moreover, since only acquisition of the position information of the mobile communication terminals is needed, it is possible to efficiently identify an installation location of an advertisement, etc. Therefore, it is possible to efficiently identify an installation location of an advertisement or a billboard where high advertising effectiveness can be achieved.
    • 在位置识别方法中,通过基于移动通信终端的位置信息计算用户的方向,并且基于用户的视线集中的位置来识别移动通信终端的用户的视线, 估计视力 通过识别移动通信终端的用户的视线的集中位置,可以识别可以实现高广告效果的安装位置。 此外,由于仅需要获取移动通信终端的位置信息,因此可以有效地识别广告的安装位置等。因此,可以有效地识别广告或广告牌的安装位置,其中 可以实现高广告效果。

    • The present invention provides a packet communication system including a mobile host, a home agent, a correspondent host, and a mobility agent, where the mobility agent operates in such a way that when the mobile host is in an active mode and has no need for buffering packets, the mobility agent forwards packets received from the home agent or the correspondent host to the mobile host; and alternatively, in the case when the mobile host is in an active mode, but requires buffering of packets, the mobility agent buffers the packets, and further in the case when the mobile host is in an idle mode, the mobility agent buffers the packet and notifies the mobile host of arrival of the packet, in order to prevent the loss of a packet addressed to a mobile host thus decreasing the traffic and the transmission frequency of Binding Update packets.
