Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication apparatus that communicates with a distant fixed station via a plurality of mobile bodies to realize inquiry and acquisition of information.
[0002]
[Prior art]
Conventionally, when obtaining information from a mobile unit, when the mobile unit requests information from a nearby fixed station wirelessly, the fixed station accesses the information server via the network, and the information server directs response information to the mobile unit. A method for replying is known.
[0003]
However, in this case, it is necessary to provide a fixed station in a range where communication from a mobile body at an arbitrary position is possible, so that there is an extra time for maintenance management of a large number of fixed stations separately from the maintenance management of the information server. It will hang.
[0004]
On the other hand, unlike the method of requesting information from a fixed station, as shown in the following (a) to (c), a mobile communication device of a method of requesting information from another mobile is known.
[0005]
(A) In the mobile communication device described in Japanese Patent Application Laid-Open No. 10-32538, information that two mobile units CR1 and CR2 hold each other when a mobile unit CR1 and a mobile unit CR2 approach each other at a communicable distance. To the other mobile units CR2 and CR1. Each of the mobile units CR2 and CR1 displays a portion important to itself among the received information on the display device.
[0006]
(B) In the mobile communication device described in Japanese Patent Application Laid-Open No. 9-180094, the traffic information held by the own vehicle is transmitted to and received from the same system installed in another vehicle. For example, the own vehicle requests one or more other vehicles for the presence or absence of traffic information. Other vehicles in the reception area of the request return the traffic congestion information to be held.
[0007]
(C) In the mobile communication device described in Japanese Patent Application Laid-Open No. 11-68643, an area on the map is designated, and information is obtained from the mobile moving in the area by inter-mobile communication. Specifically, the request for information reaches a mobile body in a predetermined area by communication between the mobile bodies. On the other hand, a reply from a moving body in a predetermined area is obtained when a moving body that has traveled in an opposite lane and approached from the predetermined area enters the communication range of the own moving body.
[0008]
[Problems to be solved by the invention]
However, in the mobile communication device as described above, according to the consideration of the present inventor, the following problems (a ′) to (c ′) may occur, and the convenience is low. Yes.
[0009]
(A ′) The mobile communication device of (a) can acquire desired information in real time only when the information held by the counterpart mobile units CR2 and CR1 matches the information desired by itself. It is. Thereby, each mobile body CR1, CR2 generally cannot acquire desired information in real time.
[0010]
(B ′) Since the mobile communication device of (b) can communicate only with other vehicles within the communication range of the own vehicle, it is difficult to obtain information on a distant point from the own vehicle in real time.
[0011]
(C ′) The mobile communication device of the above (c) cannot obtain desired information in real time because the mobile body in the opposite lane transports information when replying. In addition, since an inquiry is made in an area designated on the map, an inquiry having no designated area, such as an inquiry “where is the nearest gas station”, cannot be handled.
[0012]
The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a mobile communication device that can acquire information that is not held by another mobile in real time and can improve convenience.
[0013]
Another object of the present invention is to be able to acquire information outside of its own communication range in real time and improve convenience.
[0014]
Furthermore, another object of the present invention is to be able to acquire information in real time without specifying an area on a map, and to improve convenience.
[0015]

This is a function for sending the inquiry path information, inquiry information, and continuation range to the communication control device 24c.
[0032]
Here, the query input method is arbitrary, but from the viewpoint of simplifying the configuration, a method for selecting a desired fixed sentence from a plurality of preset fixed sentences, or in addition to this, included in the selected fixed sentence A method including selection of a query sentence (or query word or the like) set in advance, such as a method of inputting a name or a continuation range in an input area to be displayed is preferable. Further, a method that allows a desired fixed sentence to be assigned to a button or a method that is assigned in advance may be used. Alternatively, not only an input method using a fixed sentence but also a method in which necessary information is individually selected or key-inputted, such as a name input mode and a continuous range input mode. Necessary information here refers to inquiry information, continuation range and inquiry route such as facility name, accuracy of response information (outline or detail), relay continuation range, road (route) designation information, etc. Information that is a component of information.
[0033]
The continuation range is information indicating a range in which the query process is continued. In other words, the continuation range is information for ending the query process and shifting to a response process when the query process is not in the continuation range. (Eg, latitude / longitude limits), (b) time range (eg, within 30 seconds), (c) inquiry frequency range (eg, within 20 times the number of times passing through other mobile objects) , (D) the first response (or the range of the number of responses), (e) any combination of (a) to (d) above. Whether or not the continuation range is a continuation range, for example, (b) the inquiry start time when time is used as a condition, or (c) the number of times via a mobile object when the number of inquiries is used (updated for each route). It is created including information for continuation determination for determining whether or not. The continuation range may be set in advance, except for the range of the position (a).
[0034]
When the inquiry relay function receives the inquiry information transmitted from the rear moving body from the communication control device 24c via the communication device 25, the inquiry relay function does not relay the same inquiry information and is in the continuation range. This is a function for transmitting inquiry information to a mobile body ahead via the communication control device 24c and the communication device 25 by relaying information and sending it to the communication control device 24c. However, if the same inquiry information is not relayed but is not within the continuation range, a response process is executed, and the response information collected so far is sent to the communication control device 24c so that the response information is It also includes a function for sending to mobiles. Note that the response information or the like means a continuation range, response path information, inquiry information, and response information.
[0035]

Here, each route information may be information that can specify a range of position information corresponding to the route Ro, as shown in FIGS. 5 and 6 with an example of a more complicated route than FIG. In the case of the inquiry route information, as shown in FIG. 5, the current location information p1 of the inquiry transmission source, the location information p2 designating the route tip location, and the road designation information r1, r2 between the location information p1, p2 A pair is available. However, instead of the position information p2 of the route tip position, information for designating that the roads are r1 and r2 ahead from the current position information p1 (eg, road identification information, direction information, latitude / longitude condition information, etc.) May be used. This is a case where the query processing is executed when the own path information corresponds to the query path information and the own status corresponds to the continuation range. This is because even if the end of the path is undecided, it does not affect the execution / cancellation of query processing. Note that the information for designating the road ahead is necessary from the viewpoint of eliminating the meaningless process of relaying the inquiry information between the mobile bodies behind and propagating it.
[0038]
On the other hand, in the case of the response route information, as shown in FIG. 6, in the inquiry route information, the location information p2 of the route tip position is updated to the current location information p3, p4,. It has become. Note that the current position information p1, p2,... In both route information is input from the position measuring device 21 to the route processing device 24b, so that input by the operator is unnecessary.

[0044]
Next, the operation of the mobile communication system configured as described above will be described.
(Inquiry transmission processing)
Now, as shown in FIGS. 1, 4 and 7, in the mobile object A, an inquiry about desired information is input to the mobile communication apparatus 20A by the operation of the input device 23 by the user (ST1).
[0045]
In the mobile communication device 20A, the inquiry / response processing device 24a analyzes the input inquiry (ST2), and sends the inquiry information created by this analysis to the route processing device 24b.
[0046]
The route processing device 24b creates inquiry route information based on this inquiry information (ST3), and sends the obtained inquiry route information to the inquiry / response processing device 24a.
[0047]
The inquiry / response processing device 24a creates an inquiry continuation range based on the inquiry route information (ST4), and sends the obtained continuation range, inquiry route information, and inquiry information to the communication control device 24c.
[0048]
The communication control device 24c transmits the continuation range, inquiry route information, and inquiry information toward the moving body B ahead through the communication device 25 (ST5).
[0049]
(Relay processing of inquiry)
In the mobile unit B, as shown in FIG. 8, when the continuation range, inquiry route information, and inquiry information from the rear mobile unit A are received by the communication device 25 (ST11), the received content is changed to the communication control device 24c. Is input to the inquiry / response processing device 24a.
[0050]
The inquiry / response processing device 24a analyzes the inquiry information out of the continuation range, inquiry route information, and inquiry information (ST12), and inquires about the current inquiry information in response to whether the same inquiry information has already been relayed. It is determined whether or not to discard (ST13).
[0051]
If the same query information has already been relayed as a result of the determination in step ST13, the current query information and the like are discarded and the process is terminated. If the same query information has not been relayed yet, the query / response process is performed. The device 24a sends an on-route determination request and inquiry route information to the route processing device 24b.
[0052]
When the route processing device 24b receives the on-route determination request, the route processing device 24b determines whether or not it is on the inquiry route based on the inquiry route information and the position information from the position measuring device 21 (ST14). Is sent to the inquiry / response processor 24a.
[0053]
The inquiry / reply processing device 24a ends the process when the determination result indicates that it is not on the inquiry path, but when the determination result indicates that the determination result is on the inquiry path, the inquiry / reply processing device 24a enters the continuation range based on the continuation range. It is determined whether or not there is (ST15).
[0054]
If the result of the determination in step ST15 is that the self is not in the continuation range, the process proceeds to step ST21 to execute a reply process. If the self is in the continuation range, the inquiry information is sent to the communication control device 24c, so An inquiry is made to the fixed station 10pa in the object (ST16).
[0055]
After step ST16 is completed, the inquiry response processing device 24a sends the route creation request, the inquiry route information, and the continuation range to the route processing device 24b regardless of whether or not response information is received from the fixed station 10xx to be inquired. .
[0056]
When the route processing device 24b receives the route creation request, the route processing device 24b grasps its own position based on the position information from the position measuring device 21 and the map data in the map data storage unit 22 (ST17). Based on the position, the inquiry route information and the continuation range are used to update the inquiry route (ST18), and the updated inquiry route information is sent to the inquiry / response processing device 24a.
[0057]
Upon receiving the inquiry route information, the inquiry / response processing device 24a updates the continuation range (ST19), and sends the new continuation range, inquiry route information, and inquiry information to the communication control device 24c.
[0058]
The communication control device 24c transmits the continuation range, inquiry route information, and inquiry information toward the moving body C ahead via the communication device 25 (ST20).
[0059]
The front moving body C performs the processes of steps ST11 to ST20 in the same manner as described above. Similarly, each mobile unit D,... Sequentially transmits the updated continuation range and inquiry path information and the above-described inquiry information to the front mobile units E,.
[0060]
If any mobile object X indicates that the determination result of step ST15 is not within the continuation range, a response process is executed (ST21), and response information and the like are transmitted toward the rear mobile object. Here, the response information or the like means a continuation range, response path information, inquiry information, and response information. The response information is not limited to one, but means all response information collected when each mobile object is in the continuation range. Next, the relay process in the rear mobile body that has received the response information from the front mobile body will be described.
[0061]
(Reply of response)
For example, as shown in FIG. 9, in the mobile unit D, when response information or the like is received from the mobile unit C ahead by the communication device 25 (ST31), the received content is sent to the inquiry / response processing device via the communication control device 24c. 24a is input.
[0062]
When the inquiry / response processing device 24a receives the response information, the inquiry / response processing device 24a sends a route determination request and response route information to the route processing device 24b.
[0063]
Upon receiving the on-route determination request, the route processing device 24b determines whether or not it is on the response route based on the response route information and the position information from the position measuring device (ST32), and determines the determination result. It is sent to the inquiry / response processor 24a.
[0064]
The inquiry / reply processing device 24a ends the process when the determination result indicates that it is not on the response path, but when the determination result indicates that the determination result is on the response path, the inquiry / response processing device 24a already has the same response information based on the response information. It is determined whether or not to discard the current reply information in response to whether or not the message is relayed (ST33).
[0065]
If the same response information has already been relayed as a result of the determination in step ST33, the current response information and the like are discarded and the processing ends. If the same response information is not relayed yet, the inquiry / response processing is performed. The device 24a analyzes the inquiry information (ST34), and transmits the inquiry information to the fixed station 10ho of the nearby building via the communication control device 24c and the communication device 24 (ST35).
[0066]
Thereafter, when the new response information is received from the communication control device 24c via the communication device 25, the inquiry / response processing device 24a stores the new response information in the temporary storage memory 26 (ST36). Subsequently, the inquiry / reply processing device 24a compares the reply information to be relayed with the reply information in the temporary storage memory 26. If necessary, the reply information to be relayed is used as the reply information in the temporary storage memory 26. Update (ST37).
[0067]
Thereafter, the inquiry / response processor 24a determines whether or not it is a response destination based on the response path information (ST38). If the result of determination is that it is the response destination, the process proceeds to step ST41 and is displayed. The response information is displayed on the device 27. When the device 27 is not the response destination, the route creation request and the response route information are sent to the route processing device 24b.
[0068]
When the route processing device 24b receives the route creation request, the route processing device 24b grasps its own position based on the position information from the position measuring device 21 and the map data in the map data storage unit 22, and based on the grasped own position. Then, the return route information is updated to new contents (ST39), and the updated response route information is sent to the inquiry / response processing device 24a.
[0069]
When the inquiry / response processing device 24a receives the response route information, it sends the response route information, the response information, and the inquiry information to the communication control device 24c.
[0070]
The communication control device 24c transmits the response path information, the response information, and the inquiry information to the moving body C behind the communication device 25 (ST40).
[0071]
The rear moving body C executes the processes of steps ST31 to ST40 as described above. Similarly, each mobile unit B,... Transmits the updated response path information, response information, and inquiry information to the subsequent mobile units A,.
[0072]
Then, in the mobile unit A that has transmitted inquiry information for the first time, when the determination result in step ST38 is "self is a response destination", the response information is displayed on the display device 27 of the mobile communication device 20A (ST41), and a series of The process ends.
[0073]
As described above, according to the present embodiment, since information is acquired from the distant fixed station 10xx through the relay process for each mobile unit B, C,..., The other mobile units B, C,. Information can be acquired in real time, and convenience can be improved. Similarly, information outside the communication range of the user can be acquired in real time, and convenience can be improved.
[0074]
Furthermore, since information is acquired from the fixed station 10xx as response information to the inquiry information, information can be acquired in real time without specifying an area on the map, and convenience can be improved.
[0075]
Since the response route information is updated for each mobile unit D, C,... On the response route, the inquiry is made as if the mobile unit on the inquiry route is absent on the response route due to a right turn or a left turn. Even if the response path is fluidly changed with respect to the path, the processing can be realized. In other words, the mobile communication system according to the present embodiment executes the inquiry process and the reply process regardless of the match / mismatch between each mobile body constituting the inquiry path and each mobile body constituting the reply path. Can do.
[0076]
(Second Embodiment)
FIG. 10 is a schematic diagram for explaining the second embodiment of the present invention, and specifically shows an example in which the mobile communication system according to the first embodiment is applied to the inquiry of the nearest gas station gs. ing.

[0077]
First, as shown in FIG. 11 (a), in the mobile unit A, an inquiry “I want information on the nearest gas station” is input to the mobile unit communication device 20A by the operation of the operator (ST1). ).
[0078]
Subsequently, as shown in FIG. 11 (b), the mobile communication device 20A creates inquiry route information indicating the route Ro based on the inquiry (ST2 to ST3), as shown in FIG. 11 (c). The continuation range Qr of the inquiry is created (ST4). The continuation range Qr is “first response”, and since the end point is not determined because of examining the nearest one, the right end in the figure is an open end.
[0079]
Thereafter, the mobile communication device 20A transmits the continuation range Qr, the inquiry path information Ro, and the inquiry information to the front mobile body B (ST5).
[0080]
In the mobile unit B, as shown in FIG. 12A, the mobile communication device 20B determines whether or not to discard (relay) the inquiry information by analyzing the received content (ST11 to ST13). Since the same inquiry information or the like has not been relayed before, a determination result indicating that the inquiry information or the like is relayed can be obtained.
[0081]
Further, when the mobile communication device 20B is located on the inquiry path and is in the continuation range, the mobile communication device 20B makes an inquiry to the fixed station 10gs of the gasoline station gs to be inquired (ST14 to ST16). The reply information from the fixed station 10gs of gs is not received, and as shown in FIG. 12 (b), the updated continuation range, inquiry path information, and inquiry information are transmitted to the mobile unit C ahead (ST17- ST20).
[0082]
The front moving body C performs the processes of steps ST11 to ST20 in the same manner as described above. Next, in the moving body D in front of the moving body C, when the moving body transmitting device 20D receives the response information from the fixed station 10gs of the gas station gs as a result of step ST16, it satisfies the “first response” in the continuation range. Therefore, after the same steps ST17 and ST18 as described above, in step ST19, the continuation range is updated so that the self is not in the continuation range, and an inquiry is transmitted to the next mobile unit E (ST20).
[0083]
The next mobile unit E executes the processing of steps ST11 to ST15 as described above. However, as a result of step ST15, the mobile unit E is not in the continuation range of the inquiry, so the process moves to step ST21 and is shown in FIG. As described above, the response route information indicating the response route Ro ′ is created, and the response information and the like are transmitted toward the rear mobile unit D.
[0084]
In the mobile unit D, when the mobile communication device 20D receives this response information, the mobile unit D determines that it is located on the response path and has not relayed the same response information before (ST31 to ST33). A determination result for relaying the response information or the like is obtained.
[0085]
Subsequently, the mobile communication device 20D transmits the inquiry information (ST34, ST35), but cannot receive the response information (ST36, ST37) because the inquiry is “where is the nearest gas station gs”. ), And proceeds to step ST38.
[0086]
Here, the mobile communication device 20D determines whether or not the mobile communication device 20D is a response destination (ST38). Since the mobile communication device 20D is not the response destination, the mobile communication device 20D updates the response path information as shown in FIG. Then, response information and the like are transmitted toward the rear moving body C (ST39, ST40).
[0087]
As described above, the rear mobile unit C executes steps ST31 to ST40, and transmits the updated response path information, response information, and inquiry information to the rear mobile unit B as shown in FIG. . Similarly, the rear mobile unit B performs steps ST31 to ST40 and transmits response information and the like to the rear mobile unit A.
[0088]
The mobile communication device 20A of the mobile unit A executes steps ST31 to ST37 as described above, and then determines that “self is a reply destination” in step ST38. As shown in FIG. Reply information is displayed (ST41), and a series of processing is terminated.
[0089]
As described above, according to the present embodiment, in addition to the effects of the first embodiment, in a specific example of an inquiry that does not specify an area on a map, such as an example in which the nearest gas station gs is inquired, Information can be acquired in real time, and convenience can be improved.
[0090]
(Third embodiment)
FIG. 14 is a schematic diagram for explaining the third embodiment of the present invention, and specifically shows an example in which the mobile communication system according to the first embodiment is applied to information propagation. Here, as information to be propagated, emergency information such as natural disasters will be described as a representative. Needless to say, guidance information with low urgency may be propagated instead of emergency information.
[0091]
Specifically, the information to be propagated includes, in the inquiry information, in addition to the contents of the inquiry (eg, where is the nearest evacuable place), the emergency information and the propagation display necessity / unnecessary flag. If the necessity / unnecessary flag for propagation display is set to “necessary”, the inquiry is made to the display device 27 of each mobile communication device 20A, 20B,... Information is displayed.
[0092]
Similarly, as a result of step ST38, the propagated information passes through the display on the display device 27 in step ST41 and proceeds to the update of the route in step ST39 even if the reply destination is not self. . In this case, it is assumed that the propagation of information will be terminated sometime by setting the continuation range set in advance to be valid.
[0093]
In other words, the inquiry / response processing device 24a has a function of causing the display device 27 to display the inquiry information when the necessity / unnecessity flag of the propagation display is “necessary” in the inquiry information. In the case of reply processing, this function works in the same way even when the necessity / unnecessary flag in the attached inquiry information is “necessary”. In this case, the response information is displayed on the display device 27 together with the inquiry information. Works to let you.
[0094]
With the above configuration, in addition to the effects of the first embodiment, inquiry information and response information can be displayed on the mobile communication devices 20B, 20C,... Of the mobile bodies B, C,. Desired information can be propagated. Further, as shown in FIG. 14, since inquiry information and response information can be displayed on the mobile communication devices 20B, 20C,... Of the moving bodies F, G,. Can be realized.
[0095]
(Fourth embodiment)
FIG. 15 is a schematic diagram for explaining the fourth embodiment of the present invention. Specifically, an example in which the mobile communication system according to the first embodiment is applied to an inquiry in a shared area of tourist destination information. Is shown. Here, the sightseeing spot information means response information provided from each facility such as the house ho, the castle ca, the park pa, the dining room re, and the museum mu in the first and second shared areas 31 and 32. . In the present embodiment, a case where information on each facility included in the second shared area 32 is acquired will be described as an example.
[0096]
First, as shown in FIG. 16 (a), in the mobile unit A, an inquiry to the effect that "I want rough information on the second shared area 32" is input to the mobile unit communication device 20A by the operator's operation. (ST1).
[0097]
Subsequently, as shown in FIG. 16 (b), the mobile communication device 20A creates inquiry route information indicating the route Ro based on the inquiry (ST2 to ST3), as shown in FIG. 16 (c). The continuation range Qr of the inquiry is created (ST4). In this case, information (eg, address information or latitude / longitude information) for designating “range from the current position to the far boundary position of the second shared area 32” is used as the continuation range Qr.
[0098]
Thereafter, the mobile communication device 20A transmits the continuation range Qr, the inquiry path information, and the inquiry information to the front mobile body B (ST5).
[0099]
In the mobile unit B, as shown in FIG. 17A, the mobile communication device 20B determines whether to discard (relay) the inquiry information or the like by analyzing the received content (ST11 to ST13). Since the same inquiry information or the like has not been relayed before, a determination result indicating that the inquiry information or the like is relayed can be obtained.
[0100]
Further, when the mobile communication device 20B is located on the inquiry route Ro and is in the continuation range Qr, the mobile communication device 20B executes an inquiry toward the fixed station 10pa or the like of the second shared area 32 to be inquired ( ST14 to ST16), response information from the fixed station 10pa in the second shared area 32 is not received, and the updated continuation range, inquiry path information, and inquiry information are moved forward as shown in FIG. 17B. It transmits toward the body C (ST17 to ST20).
[0101]
Since the mobile unit C in the front is in the second shared area 32, the process of steps ST11 to ST16 is sequentially executed as described above, and the response information is obtained from the fixed station 10pa in the second shared area 32. The processing of ST17 to ST20 is executed.
[0102]
Further, since the other front mobile bodies D and E are also in the second shared area 32, the processes of steps ST11 to ST16 are sequentially executed as described above, and responses are received from the fixed stations 10re and 10mu in the second shared area 32. After obtaining the information, the processes of steps ST17 to ST20 are executed.
[0103]
Next, the mobile body F in front of the mobile body E executes the processing of steps ST11 to ST15 as described above. However, as a result of step ST15, the mobile body F is outside the second shared area 32, so that mobile communication is performed. It is determined that the device 20F is not within the inquiry continuation range, and the process proceeds to step ST21.
[0104]
Thereafter, as shown in FIG. 17C, the mobile communication device 20F creates response route information indicating the response route Ro ′, and transmits the response information and the like toward the rear mobile unit E.
[0105]
In the mobile unit E, when the mobile communication device 20E receives this response information, it determines that it is located on the response path and has not relayed the same response information or the like before (ST31 to ST33). A determination result for relaying the response information or the like is obtained.
[0106]
Subsequently, the mobile communication device 20E transmits inquiry information (ST34, ST35), receives response information from the fixed station 10mu in the second shared area 23 (ST36, ST37), and proceeds to step ST38.
[0107]
Here, the mobile communication device 20E determines whether or not it is the reply destination (ST38), and updates the reply path information as shown in FIG. 17 (d) because it is not the reply destination. Then, response information and the like are transmitted toward the rear moving body D (ST39, ST40).
[0108]
Each of the rear mobile bodies D to B executes steps ST31 to ST40 as described above, and sequentially moves the updated reply path information, reply information and inquiry information to the rear as shown in FIG. Send to bodies C-A.
[0109]
The mobile communication device 20A of the mobile unit A executes steps ST31 to ST37 as described above, and then determines that “self is a reply destination” in step ST38. As shown in FIG. Reply information is displayed (ST41), and a series of processing is terminated.
[0110]
However, the response information displayed in step ST41 is general information based on step ST1. Therefore, the mobile communication device 20A may inquire detailed information by designating a specific facility in the second shared area 32 by the operation of the operator.
[0111]
As described above, according to the present embodiment, in addition to the effects of the first embodiment, even in an inquiry specifying a collection of facilities instead of each facility, as in the example in which information on the second shared area 32 is queried. Information can be acquired in real time, and convenience can be improved.
