Abstract

An information processing device, method thereof and recording medium for communication regardless of the status of the terminal device. A domain name server stores the node identifier, and address for one or more mapping agents 121 corresponding to the host name of a terminal device. The domain name server receives a transmit request for the node identifier of terminal device 11 and the address of the mapping agent, sent from a terminal device, along with the host name or node identifier of terminal device 11. The domain name server 144 selects the node identifier for terminal device and address for mapping agent when the transmit request is received. The domain name server sends the node identifier for terminal device 11 and address for mapping agent to the terminal device.

a transmit step to transmit the first data and third data selected by the selection means, to the second terminal device.

3. A recording medium recorded with a computer-loadable information processing program of an information processing device for storing a first data for designating a first terminal device corresponding to the host name or node identifier of the first terminal device, as well as for storing a third data showing the position of one or more provision devices for providing a second data showing the current position of the first terminal device, comprising:

a receive step to receive a transmit request for the third data and the first data corresponding to the first terminal device, transmitted along with the host name or node identifier of the first terminal device from the second terminal device;

a selection step to select a first data corresponding to the first terminal device stored in the storage means and to select a third data showing the position of one more provision devices when the transmit request is received from the receive means; and

a transmit step to transmit the first data and third data selected by the selection means, to the second terminal device.

4. An information processing device, comprising:

first transmit means for transmitting a transmit request for a second data showing the position of one or more first provision devices, as well as a first data designating a terminal device, to a second provision device along with the name or node identifier of the terminal device;

first receive means for receiving a second data showing the position of one or more first provision devices as well as a first data for designating the terminal device from the second terminal device;

second transmit means for transmitting a request for transmission of a third data designating the position of the terminal device, along with a first data designating the terminal device, to any of the one or more first provision devices; and

second receive means for receiving the third data designating the position of the terminal device from any of the one or more first provision devices.

5. An information processing method comprising:

a first transmit step to transmit a request for a second data showing the position of one ormore first provision devices, as well as a first data designating a terminal device, to a second provision device along with the name or node identifier of the terminal device and,

a first receive step to receive a second data showing the position of one or more first provision devices as well as first data for designating the terminal device from the second terminal device;

a second transmit step for transmitting a request for transmission of a third data designating the position of the terminal device, along with a first data designating the terminal device, to any of the one or more first provision devices; and

a second receive step for receiving the third data designating the position of the terminal device from any of the one or more first provision devices.

6. A recording medium recorded with a computer-loadable information processing program, wherein said computer-loadable information processing program comprises:
