Abstract:
1. A positional information providing method configured to provide positional information on a desired mobile terminal device to an information sending server through the use of a positional information providing server connected through a network to said information sending server, comprising: a position decision request step in which said information sending server transmits desired decision positional information and unique information on a designated mobile terminal device through said network to said positional information providing server; a registration step in which a mobile terminal device transmits unique information thereon through said network to said positional information providing server; a position decision step in which, when said designated unique information and said unique information agree with each other, said positional information providing server decides as to whether there is a point of agreement between said decision positional information and positional information on said mobile terminal device; a positional information providing step in which, when the decision shows there is a point of agreement between said decision positional information and said positional information on said mobile terminal device, said positional information providing server notifies a result of the decision through said network to said information sending server for providing positional information; and a positional information registration step in which a specified terminal device existing in a short-distance radio-communicable range with respect to said mobile terminal device transmits group identification information to be used for grouping mobile terminal devices existing in said short-distance radio-communicable range and positional information thereon through said network to said positional information providing server, wherein said registration step further comprises said mobile terminal device receiving said group identification information transmitted from said specified terminal device through short-distance radio communication unit and transmitting said group identification information and unique information thereon through said network to said positional information providing server for conducting group registration, wherein in said position decision step, when said designated unique information and said unique information agree with each other, said positional information providing server makes a decision as to whether or not there is a point of agreement between said decision positional information and positional information on said specified terminal device, and wherein in said positional information providing step, when the decision shows that there is a point of agreement between said decision positional information and said positional information on said specified terminal device, said positional information providing server notifies a result of the decision through said network to said information sending server for providing the positional information.
