Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
77 words
A moving body information communication device comprising: a first communication means which receives request information from an information requesting side moving body; and a second communication means which transmits the request information to at least one moving body existing at a predetermined region, wherein when moving body information corresponding to the request information is transmitted from the moving body existing at the predetermined region, the moving body information is transferred to the information requesting side moving body.
Claim 2
Dependent Claim
77 words
A moving body information communication device comprising: a first communication means which receives request information from an information requesting side moving body; and a second communication means which transmits the request information to at least one moving body existing at a predetermined region, wherein when moving body information corresponding to the request information is transmitted from the moving body existing at the predetermined region, the moving body information is transferred to the information requesting side moving body.
Claim 3
Dependent Claim
85 words
A moving body information communication device according to claim 1 , further comprising a memory which stores moving body information which is always being received from each moving body, wherein when the request information is stored in the memory, the moving body information communication device reads the stored information and transfers the same to the information requesting side moving body and when no request information is stored in the memory, the device transmits the request information to the moving body existing at the predetermined region.
Claim 4
Dependent Claim
66 words
A moving body information communication device according to claim 2 , wherein when the request information is not stored in the memory, it is judged whether the communication traffic of the moving body information communication device is within a predetermined allowable value, and when the communication traffic is within the predetermined allowable value, the device transmits the request information to the information requesting side moving body.
Claim 5
Dependent Claim
61 words
A moving body information communication system comprising a plurality of moving body information communication devices connected through a network, wherein each of the moving body information communication devices is constituted according to claim 3 and further comprises a moving body management means which receives moving body identification ID and position information periodically declared by the moving body and manages the same.
Claim 6
Dependent Claim
61 words
A moving body information communication system comprising a plurality of moving body information communication devices connected through a network, wherein each of the moving body information communication devices is constituted according to claim 2 and further comprises a moving body management means which receives moving body identification ID and position information periodically declared by the moving body and manages the same.
Claim 7
Dependent Claim
61 words
A moving body information communication system comprising a plurality of moving body information communication devices connected through a network, wherein each of the moving body information communication devices is constituted according to claim 1 and further comprises a moving body management means which receives moving body identification ID and position information periodically declared by the moving body and manages the same.
Claim 8
Dependent Claim
148 words
A moving body information communication device comprising: a first communication means which receives request information from an information requesting side; a second communication means which transmits the request information to at least one moving body existing at a predetermined region; and a memory which stores moving body information which is always being received from the moving body, wherein when the request information is stored in the memory, the moving body information stored in the memory is classified according to its freshness and when the freshness of the information is within a predetermined freshness threshold value, the moving body information is determined to be transferable to the information requesting side, the moving body information communication device reads the transferable stored information and transfers the same to the information requesting side, and when no request information is stored in the memory, the device transmits they request-information to the moving body.
Claim 9
Dependent Claim
148 words
A moving body information communication device comprising: a first communication means which receives request information from an information requesting side; a second communication means which transmits the request information to at least one moving body existing at a predetermined region; and a memory which stores moving body information which is always being received from the moving body, wherein when the request information is stored in the memory, the moving body information stored in the memory is classified according to its freshness and when the freshness of the information is within a predetermined freshness threshold value, the moving body information is determined to be transferable to the information requesting side, the moving body information communication device reads the transferable stored information and transfers the same to the information requesting side, and when no request information is stored in the memory, the device transmits they request-information to the moving body.
Claim 10
Dependent Claim
63 words
A moving body information communication device according to claim 7 , wherein when the request information is not stored in the memory, it is judged whether the communication traffic of the moving body information communication device is within a predetermined allowable value, and when the communication traffic is within the predetermined allowable value, the device transmits the request information to the moving body.
Claim 11
Dependent Claim
61 words
A moving body information communication system comprising a plurality of moving body information communication devices connected through a network, wherein each of the moving body information communication devices is constituted according to claim 8 and further comprises a moving body management means which receives moving body identification ID and position information periodically declared by the moving body and manages the same.
Claim 12
Dependent Claim
61 words
A moving body information communication system comprising a plurality of moving body information communication devices connected through a network, wherein each of the moving body information communication devices is constituted according to claim 7 and further comprises a moving body management means which receives moving body identification ID and position information periodically declared by the moving body and manages the same.
Claim 13
Independent Claim
158 words
A method of moving body information communication between an information requesting side, a moving body information communication device and a moving body, wherein when the moving body information communication device receives request information from the information requesting side, the device retrieves a memory and when there is moving body information meeting the request information therein, the device returns the moving body information meeting the request information contained in the memory to the information requesting side and when there is no moving body information meeting the request information therein, the device transmits the request information to the moving body, when the moving body which is always collecting moving body information holds the moving body information meeting the received information request, the moving body transmits the holding moving body information to the moving body information communication device, and the moving body information communication device further transmits the moving body information received from the moving body to the information requesting side.
