1. A method for operating a message exchanging system including a plurality of access points that transmit annunciation signals including their addresses, a portable terminal configured to be connected to a wide area network and to receive the annunciation signals transmitted from the access points, and a message server that is connected to the wide area network and stores a message table in which a message is associated with each set of the addresses of the plurality of access points, in order for the portable terminal to acquire the message from the message server, the method comprising:

  • a first step, effected though the portable terminal, of searching for access points in a vicinity of the portable terminal and receiving the annunciation signal including the address of the access point from each of searched access points;

    a second step, effected though the portable terminal, of transmitting to the message server, a message acquisition request which includes, as a query, a set of the addresses of the searched access points included in the annunciation signals;

    a third step, effected though the message server, of comparing the set of the addresses as the query which is included in the message acquisition request, with a plurality of sets of addresses recorded in the message table stored in the message server, and extracting a message corresponding to a set of the addresses which ranks high among the sets of the addresses that are arranged in descending order of similarity; and

    a fourth step, effected though the message server and the portable terminal, of transmitting the extracted message as a response to the portable terminal such that the portable terminal exchanges messages with other portable terminals which are in a vicinity of the portable terminal.
