Abstract

A route search system includes mobile terminals provided with wireless communications function, and a route supply server. The route supply server includes a route map database that stores a route map; a positional information obtaining section that obtains respective pieces of positional information of the mobile terminals; a point and route calculating section that searches the route map database based on the respective pieces of positional information of the mobile terminals obtained by the positional information obtaining section, and determines a meeting point for users carrying the mobile terminals, respectively, and respective moving routes to the meeting point for the users; and a point and route notifying section that provides notification of the meeting point and each of the moving routes to the meeting point determined by the point and route calculating section to each of the mobile terminals carried by each of the users.

Claims

1. A route search system comprising:

a plurality of mobile terminals provided with wireless communications function; and

a route supply server comprising;

a route map database that stores a route map,

a positional information obtaining section that obtains respective pieces of positional information of the plurality of mobile terminals,

a point and route calculating section that searches the route map database based on the respective pieces of positional information of the plurality of mobile terminals obtained by the positional information obtaining section, and determines a meeting point for a plurality of users carrying the plurality of mobile terminals, respectively, and respective moving routes to the meeting point for the plurality of users as well, and

a point and route notifying section that provides notification of the meeting point and each of the respective moving routes to the meeting point determined by the point and route calculating section to each of the mobile terminals carried by each of the users.

2. The route search system according to claim 1, wherein the route map database stores a route map including point names with positional information and a railroad map that links one point with another point.

3. The route search system according to claim 2, wherein the route map database stores a route map including station names with positional information and a public train map that links one station with another station.

4. The route search system according to claim 1, wherein the mobile terminal includes a GPS function that obtains positional information, and transmits the obtained positional information to the route supply server by using the GPS function.

5. A mobile terminal including wireless communications function, the mobile terminal comprising:

a point and route search request section that specifies a mobile terminal carried by other user and requests searching of a meeting point with the other user carrying the mobile terminal and a moving route to the meeting point, wirelessly to a route supply server that determines a meeting point for a plurality of users carrying a plurality of mobile terminals, respectively, as well as respective moving routes to the meeting point for the plurality of users, and notifies each of the mobile terminals carried by each of the users; and

a point and route notification section that receives the meeting point and the moving routes transmitted from the route supply server, in response to the request by the point and route search request section, and notifies a user carrying the mobile terminal.

6. The mobile terminal according to claim 5, further comprising a GPS function that obtains positional information, and

wherein the point and route search request section notifies the route supply server of positional information obtained by using the GPS function, to request searching of the meeting point and a moving route to the meeting point.

7. A route supply server comprising:

a route map database that stores a route map;

a positional information obtaining section that receives, from a mobile terminal, a request in which other mobile terminal is specified, of searching a meeting point with a user of the other mobile terminal and a moving route to the meeting point, and obtains respective pieces of positional information of the mobile terminal and the other mobile terminal;

a point and route calculating section that searches the route map database based on the respective pieces of positional information of the mobile terminal and the other mobile terminal obtained by the positional information obtaining section, and determines a meeting point of the users carrying the mobile terminal and the other mobile terminal, respectively, as well as respective moving routes to the meeting point for each of the users; and

a point and route notifying section that provides notification of the meeting point and each of the respective moving routes to the meeting point determined by the point and route calculating section to the mobile terminal and the other mobile terminal carried by each of the users.
