Method and system for causing portable terminal to obtain site page of web server associated with current location

A page acquisition method performed in a system including a plurality of site servers that are connected to a wide area network, a plurality of access points that transmit annunciation signals including their addresses, a portable terminal that is connected to the wide area network and acquires pages from the site servers, and a proxy server that includes an address correspondence table in which an address of a site page is associated with an address of each access point and the proxy server is connected to the wide area network, the method comprising:

• a first step of allowing the portable terminal to search for the access points in a vicinity of the portable terminal, to receive the annunciation signal including the address of the access point from each access point, and to measure a reception level of the annunciation signal;
• a second step of allowing the portable terminal to transmit, to the proxy server, a page acquisition request including list information in which the addresses of a plurality of access points included in the annunciation signals are arranged in descending order of the reception levels;
• a third step of allowing the proxy server to search for the address of the site page corresponding to the address of each access point included in the page acquisition request, using the address correspondence table;
• a fourth step of allowing the proxy server to associate the searched address of the site page with the address of each access point in the list information;
• a fifth step of allowing the proxy server to transmit the list information, which is associated with the addresses of the site pages, as a response to the portable terminal;
• and
• a sixth step of allowing the portable terminal to present the received list information to a user and to transmit one or more page acquisition requests having one or more addresses as destinations to the corresponding site servers.

A system comprising:

• a plurality of site servers that are connected to a wide area network;
• a plurality of access points that transmit annunciation signals including their addresses;
• a portable terminal that is connected to the wide area network and acquires pages from the site servers;
• and
• a proxy server that is connected to the wide area network and includes an address correspondence table in which an address of a site page is associated with an address of each access point and stored,
• wherein the portable terminal includes:
• an annunciation signal receiving element that searches for the access points in a vicinity of the portable terminal, receives the annunciation signal including the address of the access point from each access point, and measures a reception level of the annunciation signal;
• a first page acquisition request transmission element that transmits, to the proxy server, a page acquisition request including the address of each access point included in the annunciation signal and the measured reception level;
• and
• a second page acquisition request transmission element that presents the list information to a user and transmits one or more page acquisition requests having one or more addresses as destinations to the corresponding site servers, and
• the proxy server includes:
• an address search element that searches for the address of the site page corresponding to the address of each access point included in the page acquisition request, using the address correspondence table;
• a list information generation element that generates list information in which the searched addresses of a plurality of site pages are arranged in descending order of the reception levels;
• and
• a list information response element that transmits the list information as a response to the portable terminal.

A system comprising:

• a plurality of site servers that are connected to a wide area network;
• a plurality of access points that transmit annunciation signals including their addresses;
• a portable terminal that is connected to the wide area network and acquires pages from the site servers;
• and
• a proxy server that is connected to the wide area network and includes an address correspondence table in which an address of a site page is associated with an address of each access point and stored,
• wherein the portable terminal includes:
• an annunciation signal receiving element that searches for the access points in a vicinity of the portable terminal, receives the annunciation signal including the address of the access point from each access point, and measures a reception level of the annunciation signal;
• a first page acquisition request transmission element that transmits, to the proxy server, a page acquisition request including list information in which the addresses of a plurality of access points included in the annunciation signals are arranged in descending order of the reception levels;
• and
• a second page acquisition request transmission element that presents the received list information to a user and transmits one or more page acquisition requests having one or more addresses as destinations to the corresponding site servers, and
• the proxy server includes:
• an address search element that searches for the address of the site page corresponding to the address of each access point included in the page acquisition request, using the address correspondence table;
• a list information generation element that associates the searched address of the site page with the address of each access point in the list information;
• and
• a list information response element that transmits the list information, which is associated with the addresses of the site pages, as a response to the portable terminal.
