Position data notification system and position data notification method

A position search server utilized for a position data notification system and capable of communicating with communication terminals through a network, said server comprising:

• a receiving section for receiving a requests and information data from communication terminals;
• a transmitting section for transmitting information data to the communication terminals;
• an email message creating section for creating an email including information, that differs depending on which communication terminal receives the email, according to the request and information received by the receiving section;
• and
• a map creating section for creating a map indicating a current position of the communication terminal;
• wherein, when said receiving section receives a position search request for requesting for searching a current position of a second communication terminal and address data of the second communication terminal from a first communication terminal, said email message creating section prepares an email including information suitable for said second communication terminal, and said transmitting section transmits said email created by said email message creating section to said second communication terminal, and
• wherein, when said receiving section receives a current position information of the second communication terminal by performing. a predetermined process to said email by the second communication terminal, said map creating section creates a map indicating the current position of said second communication terminal according to the current position information.

A position data notification method, for providing a notification of the current position of a communication terminal, using a position data notification system that includes said communication terminal and a server that communicates with said communication terminal via a network, comprising:

• an email transmission step of said server, upon receiving from a first communication terminal a position search request for the performance of a search for the current position of a second communication terminal and for destination data to be used for connecting with said second communication terminal, transmitting to said second communication terminal an email including information that differs, depending on which communication terminal receives said email;
• a current position information notification step of said second communication terminal performing a predetermined process for an email received from said server and transmitting to said server current position data for said second communication terminal;
• and
• a map creating step of said server employing said current position data to create a map indicating the current position of said second communication terminal.
