<A. Overview>
The present disclosure provides a configuration in which a destination is set according to a communication state as a movement control of a moving body. FIG. 1 is a diagram schematically showing a vehicle 100 including the information processing device 30 according to the present embodiment and its surrounding environment. The vehicle 100 is an embodiment of a “moving body”. In this embodiment, the "mobile" may include public or private or automatic or manual transportation, including at least one of vehicles such as cars or motorcycles, bicycles, robots, personal mobility and the like. .. The information processing device 30 is a computer mounted on a mobile body. This computer is realized, for example, using hardware that follows a general-purpose architecture. Hereinafter, the information processing device 30 is also abbreviated as the device 30.

With reference to FIG. 1, one or a plurality of other moving bodies, the vehicle 110, travel around the vehicle 100.

The vehicle 100 provides a mobility office, which is an office environment constructed in a movable vehicle, and a device 30 mainly controls the mobility office. By using the mobility office, the user can perform work (telework) such as video conferencing in the vehicle while moving in the vehicle 100. The work carried out in the mobility office is not limited to video conferencing.

In FIG. 1, the device 30 of a mobile body (vehicle 100, vehicle 110) communicates with other devices such as a mobile body, a management server 700, an operator terminal of a company, etc. via a plurality of base stations 800 and a network 720. .. The mobile further detects its position on the map by communicating with the GPS (Global Positioning System) satellite 710 and transmits it to other devices such as the management server 700 via the base station 800 closest to the detection position. To do. Therefore, the management server 700 can manage the position of each mobile body. In the present embodiment, the points (for example, the position of the moving body, the destination, the confluence point, the place, etc.) are treated as the positions on the map, but the points can also be treated as a concept unrelated to the map. .. For example, a point may be treated by a place name.

In the above embodiment, the device 30 sets a common destination among the plurality of moving bodies as a destination on the map of the moving body (step T1). While the mobile body is moving to the destination, the device 30 acquires a communication state such as a load applied to communication between the mobile body and the nearest base station 800 (step T2), and whether or not the communication state satisfies a predetermined condition. Is determined (step T3). When the device 30 determines that the communication state does not satisfy the predetermined condition, the device 30 resets the destination by changing the destination so that the communication state acquired by the route to the destination satisfies the predetermined condition ( Step T1).

As a result, in the present embodiment, when the destination shared by the moving body (for example, vehicle 100) with another moving body (for example, vehicle 110) is reset, the moving body is moving to the destination. In the above, the communication state between the mobile body and the nearest base station 800 can be reset to a destination (for example, changed to another destination) so as to satisfy a predetermined condition.

Therefore, when the user performs telework in the mobile body, the destination is set (reset) during the movement so that the communication state between the mobile body and the nearest base station 800 satisfies a predetermined condition. It is possible to reach a destination shared with other mobiles without suffering from the inability to receive work information.

In the present embodiment, as a destination common to a plurality of mobile bodies, a destination whose communication state satisfies a predetermined condition is set, but the destination is not limited to the case common to the plurality of mobile bodies. For example, in the case where one moving body moves to the destination, the present embodiment is similarly applied to the case where the destination is set so that the communication state on the moving path of the moving body satisfies a predetermined condition. Can be applied.

In the present embodiment, the "map" is a so-called road map, which is a reduced route (corresponding to a road) on a part or all of the ground on which a vehicle can move and is expressed on a two-dimensional plane. .. On the map, routes are symbolized and major geographical goals, including buildings, are symbolized at their location on the map. In this embodiment, the "destination" may include such a geographical goal.

For example, the destination setting unit 406 determines (sets or changes) the destination from the output of the communication state determination unit 404, and stores the determined destination information 315 in the HDD 310. When setting the destination, the destination setting unit 406 can refer to the analysis result of the schedule information by the schedule management unit 405. The device 30 outputs the determined destination information 315 to the navigation device 51 via the communication control unit 414, and transmits the determined destination information 315 to the linked mobile unit via the network communication unit 413.

With reference to FIG. 6, the communication state DB701 on the map is associated with each of a plurality of points on the map, and has a point ID (Identifier) 71 such as a name for identifying the point, and a position measured by GPS for the point. Includes a GPS position 72, communication speed (Up) 73, communication speed (down) 74, and date and time 75. The date and time 75 indicates the date and time when the associated communication speed (Up) 73 and communication speed (down) 74 are stored in the communication state DB 701 on the map.

The communication state detection unit 402 of the mobile body instructs the wireless communication information acquisition unit 409 to acquire the communication speed in the communication between the mobile body and the nearest base station 800. The wireless communication information acquisition unit 409 measures the communication speed (Up) and the communication speed (down) from the information communicating with the nearest base station 800 via the wireless communication unit 412 and the wireless communication information acquisition unit 409 in accordance with the instruction. The map DB access unit 403 accesses the map communication status DB 701 of the management server 700 via the network communication unit 413. In the access, the map DB access unit 403 associates the communication speed (Up) and the communication speed (Up) with the point ID 71 corresponding to the ID of the nearest base station 800 received by the wireless communication information acquisition unit 409 in the communication state DB 701 on the map. down) is written (stored) as the communication speed (Up) 73 and the communication speed (down) 74, respectively. In this way, the communication state detection unit 402 periodically outputs the above instruction to the wireless communication information acquisition unit 409 each time it passes through each base station 800, for example.

As described above, the information of the communication state DB 701 on the map is updated every time each mobile body passes the point of the base station 800. Therefore, the management server 700 uses the information of the communication state DB 701 on the map as a communication speed map in which the communication speed measured at each point on the map is recorded at each point on the map, which is information that the mobiles can share with each other. Can be provided.

In the present embodiment, the communication state DB 701 on the map is provided in the management server 700, but it may be stored in the HDD 805 of each base station 800. In this case, the mobile body can acquire a communication speed map recording the communication speed measured at each point on the map from the communication state DB 701 on the nearest base station 800 map. For example, the communication speeds 73 and 74 of the nearest base station 800 can be acquired.

(G2. Destination candidate DB702)
FIG. 7 is a diagram showing an example of the destination candidate DB 702 according to the present embodiment. With reference to FIG. 7, the destination candidate DB 702 stores information associated with each of the plurality of candidates on the map that can be the destination of the moving object.

The destination candidate DB 702 stores the facility ID 61 that identifies the candidate facility, the facility name 62, the facility address 63, the equipment 64 that the facility has, and the purpose of use 65 of the facility in association with each of the plurality of destination candidates. To. Equipment 64 includes, for example, a TV (Television) conferencing system, an MFP, a wireless LAN, and the like. The purpose of use 65 includes, for example, work and actions performed at the user's facility such as a meeting, a meeting, a TV conference, and printing of materials. The facility ID 61 indicates the location information of the facility measured by, for example, GPS.

(G3. Radio base station DB803)
FIG. 8 is a diagram showing an example of the radio base station DB803 according to the present embodiment. With reference to FIG. 8, the radio base station DB803 associates with each base station 800, the base station ID 91 for identifying the base station 800, the GPS position 92 measured by the GPS of the base station 800, and the communication traffic (Up) 93. , Communication traffic (Down) 94, and date and time 95 when communication traffic (Up) 93 and communication traffic (Down) 94 were measured (stored).

The base station 800 periodically stores the communication traffic measured by the communication traffic measuring device 807 in its own base station 800 in the radio base station DB803 and transmits it to another base station 800. The base station 800 also stores the communication traffic received from the other base station 800 in the radio base station DB803. Thereby, each base station 800 can manage the radio base station DB803 so as to show the latest communication traffic value common to the other base stations 800.

The communication traffic represents the band usage amount used for the communication among the predetermined communication bands that each base station 800 has for communicating with the mobile body, and as the communication traffic increases, the band usage amount also increases, and the communication traffic As the number decreases, so does the bandwidth usage. Therefore, when the communication traffic measured by the base station 800 increases, the communication between the mobile body and the base station 800 becomes slow, and when the communication traffic decreases, the communication between the mobile body and the base station 800 Will be fast.

The communication traffic information of each base station 800 of the radio base station DB803 can be used as auxiliary information when the mobile or management server 700 acquires the communication load of the nearest base station 800 of the mobile.

In the present embodiment, the wireless base station DB 803 is provided in the base station 800, but may be stored in the HDD 706 of the management server 700. In this case, the DB management unit 709 of the management server 700 periodically receives the communication traffic 93 and 94 measured by the base station 800 from each of the base stations 800 together with the measurement time, and the received data is wirelessly received by the HDD 706. It is stored in the base station DB 803 in association with the base station ID 91 and the GPS position 92 of the base station 800. As a result, the mobile unit can acquire the communication traffic 93 and 94 of each base station 800 including the nearest base station 800 from the radio base station DB 803 of the management server 700.

Schedule 82 includes date 821 and action 822. The action 822 is an action planned by the user at the destination, and includes, for example, a meeting, a meeting, a TV conference, and the like. Action 822 may include the type and size of file 90 used in the task. The type of action indicated by action 822 corresponds to the type of purpose 65 for which the user uses the facility shown in FIG. 7.

<H. Destination reset due to changes in communication status on the moving route>
FIG. 10 is a diagram schematically showing a case where the destination reset according to the present embodiment is carried out. In FIG. 10, events T1 to T5 that occur during the movement of the moving body are shown. FIG. 11 is a diagram showing a sequence for resetting the destination according to the present embodiment in relation to the processing of each device. With reference to FIGS. 10 and 11, while a mobile body is moving to the destination, the destination is reset according to the communication state in the communication between the mobile body and the nearest base station 800 no longer satisfying the predetermined conditions. The case of (changing) will be explained.

In this case, referring to FIG. 10, a rental office where both users of the mobile body (1) corresponding to the vehicle 100, which is a cooperative mobile body, and the mobile body (2), which is another vehicle 100, are destination facilities ( Move toward the rental office (1) to join in 1). Both users prepare materials in the moving body for the meeting of the rental office (1). The device 30 of each mobile receives the document file 90 from the management server 700. Hereinafter, the processing will be described in association with the events T1, T2-2, T3, T4, T4-2, and T5 of FIG.

(T1: The communication band is reduced due to the congestion of the mobile body (X))
While the mobile body (1) is moving toward the rental office (1), which is the original destination, the communication traffic of the base station 800 on the route causes traffic congestion of the mobile body (X) on the route. (Step S1 in FIG. 11). The mobile body (X) measures the communication speed in the measured communication with the nearest base station 800, and transmits it to the management server 700 together with the position information and the time information of the date and time (step S3). Based on the information received from the mobile body X, the DB management unit 709 of the management server 700 associates the received communication speed with the point ID 71 of the nearest base station 800 and sets the communication speed (Up) 73 to the communication state DB 701 on the map. And stored as the communication speed (down) 74 (update the communication speed (Up) 73 and the communication speed (down) 74) (T2-1, step S5 in FIG. 11). As described above, the communication speed (Up) 73 and the communication speed (down) 74 of the nearest base station 800 decrease due to factors such as traffic congestion. Alternatively, since the communication traffic 93 and 94 of the nearest base station 800 increases, the communication band available in the nearest base station 800 decreases. In the present embodiment, the available communication band can be calculated by subtracting the communication band calculated based on the communication traffic 93 and 94 from the communication band allocated to the nearest base station 800.

(T2-2: Reception of communication band and detection of change)
While the mobile body (1) is moving, it becomes difficult for the communication state between the mobile body (1) and the nearest base station 800 to satisfy a predetermined condition due to the above-mentioned traffic jam.

The mobile body (1) uses the communication band information for communicating with the nearest base station 800 as the communication traffic 93, 94 of the radio base station DB 803 of the nearest base station 800 or the base of the communication state DB 701 on the map of the management server 700. It can be received from the communication speeds 73 and 74 of the station 800. The mobile body (1) can detect the margin in the communication band with the mobile body of the nearest base station 800 based on the communication traffic 93 and 94 received from the management server 700. Further, the mobile body (1) can detect the communication speed between the mobile body (1) and the nearest base station 800 based on the communication speeds 73 and 74 of the base station 800 in the communication state DB 701 on the map.

The wireless communication information acquisition unit 409 of the mobile body (1) receives communication traffic 93 and 94 of the base station from the wireless base station DB 803 of the nearest base station 800 by polling at regular intervals, and also receives the communication traffic 93 and 94 of the base station from the DB of the management server 700. The management unit 709 receives the communication speeds 73 and 74 of the base station 800 referenced (read) from the communication state DB 701 on the map (step S11 in FIG. 11).

(T3: Determine whether the required communication band can be secured (determination of communication status))
The mobile body (1) determines whether or not the communication state with the nearest base station 800 satisfies a predetermined condition (step S13). Specifically, when the destination management unit 400 detects a change in the communication speeds 73 and 74, the communication state determination unit 404 determines whether or not the load applied to the communication with the mobile body of the nearest base station 800 satisfies a predetermined condition. Is determined. More specifically, the communication state determination unit 404 compares the communication speeds 73 and 74 with the threshold value, and determines whether or not the communication speed 73 and 74 exceeds the threshold value based on the comparison result. When the communication speeds 73 and 74 are equal to or less than the threshold value, the communication between the mobile body (1) and the management server 700 is adversely affected, and the mobile body (1) cannot receive the file 90 necessary for the work. Work efficiency is reduced. In order to avoid this, the destination setting unit 406 changes (resets) the destination so that the moving body (1) can move to the destination while securing the communication speeds 73 and 74 exceeding the threshold value. carry out. On the other hand, when the communication speeds 73 and 74 exceed the threshold value, the destination is not reset (YES in step S13). The process returns to step S11.

The determination of whether the communication state satisfies the predetermined condition may be performed based on the communication traffic 93, 94 of the base station 800 received from the nearest base station 800. When the communication traffic 93,94 of the wireless base station DB803 is used for the determination, the communication state determination unit 404 communicates with the nearest base station 800 from the average communication speed of the mobile body (1) and the communication traffic 93,94. In that case, it is possible to predict how much communication speed can be secured. For example, if the average communication speed is 5 MB / sec and the traffic of the nearest base station 800 on the route is increased by 30% from the traffic of the nearest base station 800 immediately before, the communication speed is up to 3.5 MB / sec. It can be calculated when it decreases.

The judgment criterion is the maximum traffic determined from the size of the work file 90 determined from the user's schedule 82, or the maximum traffic required in the work history (communication of the file 90, etc.) or the system 1. (For example, the speed at which a 50 MB file 90 can be received in 10 seconds) is included.

The communication state of the mobile body (1) with the nearest base station 800 does not satisfy the predetermined condition (NO in step S13), that is, the communication state determination unit 404 determines the communication speed of the mobile body (1) with the nearest base station 800. When it is determined that is equal to or less than the threshold value, the destination management unit 400 determines whether the moving body (1) can change the destination.

As described above, the determination of the communication state may include at least one of the determination based on the detection (measurement) of the actual communication state on the moving path and the determination based on the predicted communication state.

(T4: Reset destination)
The destination setting unit 406 resets the destination of the moving body (1). Specifically, the destination setting unit 406 changes the destination of the moving body (1) from the rental office (1), which is the original destination, to another destination.

The destination setting unit 406 receives the position information of the current position of the moving body (2) from the moving body (2) which is a cooperative moving body via the cooperation unit 410 (T4-1 in FIG. 10 and FIG. 11). Step S17), the destination is reset, and the reset destination information is output to the navigation device 51 (T4-2).

(T4-2: Destination resetting process)
In T4-2, the destination setting unit 406 executes the destination resetting process. In the destination resetting process, the destination setting unit 406 reads the schedule 82 of the user of the mobile body (1) from the schedule DB 80 via the schedule management unit 405. The map DB access unit 403 searches for the destination candidate DB 702 based on the read action 822 of the schedule 82. Action 822 is assumed to be a "meeting". Based on the result of this search, candidate information (facility ID 61, name 62, address 63, etc.) of one or more destinations associated with the purpose of use 65 corresponding to action 822 (“meeting”) is read out (step S19). ). According to FIG. 7, for example, the information of the rental office (1X) and the rental office (2) is read out as a candidate.

The destination setting unit 406 sets each candidate as a new destination from the candidates of the destination in the order of the cooperative moving bodies, that is, the candidates having the shortest distance from the current location of the moving bodies (1) and the moving bodies (2). Judge whether or not. Here, the destination setting unit 406 obtains the distance between the moving objects (1) and (2) and each candidate, the current position by GPS acquired by the position information acquisition unit 407 of each moving object, and each candidate. It is calculated from the GPS position indicated by the facility ID 61.

The destination setting unit 406 calculates a candidate route, which is a route on the map from the moving body (1) to the candidate site, for each candidate site in ascending order of distance.

When the moving body (1) moves along the route to the candidate site, the destination setting unit 406 determines whether the communication state between the moving body (1) and the nearest base station 800 satisfies a predetermined condition during the movement. (Step S21). Specifically, the destination setting unit 406 searches the communication state DB701 on the map based on the route position (GPS information), and based on the search result, all the base stations having the GPS position 92 close to the route position. Read out the communication speeds 73 and 74 of 800. The destination setting unit 406 determines whether the communication speed of all the read base stations 800 exceeds the threshold value.

When the destination setting unit 406 determines that the communication speeds of all the base stations 800 read out for the route to the candidate site exceed the threshold value, the destination setting unit 406 determines the candidate site as a new destination (destination after the change). (Step S23). When a plurality of candidate destinations are determined as new destinations, the destination setting unit 406 may display a plurality of destination candidates on the display 372 via the display control unit 401. The user may select one of the plurality of destination candidates and instruct the destination setting unit 406 via the input unit 411.

On the other hand, the destination setting unit 406 cannot determine a new destination and changes the destination when the communication state in the route does not satisfy the predetermined condition and cannot be determined as the destination. Not done. Therefore, the destination setting unit 406 displays a message on the display 372 via the display control unit 401 that there is a section in which the communication speed drops in the route to the destination (rental office (1)).

In the above, the rental office (1X) and the rental office (2) are acquired as one or more candidates for resetting the destination, but the candidates for the destination may be narrowed down based on the equipment 64. Specifically, the destination setting unit 406 includes the types of equipment 64 provided by each of the plurality of destination candidates on the map indicated by the destination candidate DB 702, and the equipment 64 provided by the original destination (rental office (1)). One or more destination candidates to be reset are determined from the plurality of destination candidates based on the comparison result.

More specifically, the destination setting unit 406 compares and compares the equipment 64 of the rental office (1X) and the rental office (2) with the equipment 64 of the rental office (1) which is the original destination. Based on the result of the above, the candidate who does not have the kind of equipment indicated by the equipment 64 of the rental office (1) which is the original destination is excluded from the target of resetting the destination. In the case of FIG. 7, since the equipment 64 of the rental office (1X) does not have the MFP provided in the equipment 64 of the rental office (1) which is the original destination, the destination setting unit 406 aims at the rental office (1X). Remove from candidates for land resetting. Alternatively, if the action (work) performed at the destination is, for example, a TV conference from the user's schedule 82, it can be determined that the work does not use the MFP. If it can be determined in this way, the destination setting unit 406 may also use the rental office (1X) as a candidate for the destination for resetting.

The cooperation unit 410 transmits the reset destination information to the cooperation mobile body (2) (T4-3). The mobile body (2) receives the reset destination information, stores the received information as the destination information 315 in the HDD 310, and sets the received information as the destination information 315 in the navigation device 51 of the travel control system (). Step S29). Further, the destination setting unit 406 of the moving body (1) sets the destination information 315 indicating the changed destination in the navigation device 51 (step S25). As a result, a common destination is reset (changed) between the moving bodies (1) and (2).

(T5: Move to the reset destination)
In the moving body (1) and the moving body (2), the fact that the destination information 315 has been reset (changed) is displayed on the display 372 via the display control unit 401, and the moving body (1) and (2) are displayed. ) Moves to the reset destination (step S27, step S31).

In FIGS. 10 and 11, the destination was reset starting from the case where the mobile body (1) changed the communication speed between the mobile body and the nearest base station 800 during movement, but this was the first time. It may be carried out at the time of setting the destination. For example, the destination setting unit 406 sets the rental office (1) as the destination according to the user operation received via the input unit 411 at the departure point of the moving body (1), but sets the destination at the time of departure. In the destination setting unit 406, it may be determined whether the communication state in the route to the destination specified by the user satisfies a predetermined condition, and another destination may be set based on the determination result. Further, when the destination setting unit 406 determines that there is a non-communicable section such as a tunnel in the route to the destination, the destination setting unit 406 may reset the destination.

In the processes of FIGS. 10 and 11, the destination is reset on the moving body (1) side that operates in cooperation with each other, but the same processing of the destination resetting may be performed on the moving body (2). .. Further, although the number of moving bodies that cooperate with each other is two, that is, the moving body (1) and the moving body (2), three or more moving bodies may cooperate with each other.

<I. Resetting the destination according to the work content on the move>
FIG. 12 is a diagram schematically showing another case in which the resetting of the destination according to the present embodiment is carried out. In FIG. 12, events R1 to R5 that occur during the movement of the moving body are shown. FIG. 13 is a diagram showing another sequence for resetting the destination according to the present embodiment in relation to the processing of each device. FIG. 14 is a diagram schematically showing communication band information 316 according to the present embodiment. FIG. 14 shows a communication band required for communicating information for the work for each work (conference call, TV conference, etc.). With reference to FIGS. 12 and 13, the communication state in the communication between the mobile body and the nearest base station 800 does not satisfy the predetermined condition due to the change in the work performed in the mobile body during the movement. The case of resetting (changing) the destination will be described.

In FIGS. 12 and 13, the management server 700 stores the wireless base station DB803 in the HDD 706, and the mobile body acquires the communication traffic 93 and 94 of each base station 800 by communicating with the management server 700. The mobile unit may acquire communication traffic 93, 94 of each base station 800 from the radio base station DB 803 of the HDD 805 of the nearest base station 800.

In FIG. 12, the mobile body (1) is heading to the rental office (1) for work (R1). The wireless communication information acquisition unit 409 of the mobile body (1) communicates with the management server 700 by polling at regular intervals, and from the wireless base station DB803 of the management server 700, the communication band information of the nearest base station 800 (communication traffic 93, 94) is received (step S7 in FIG. 13).

When the user of the mobile body (1) requests help from the operator terminal in order to promote the work (R1-1), the operator terminal tells the user of the other mobile body (2) to the mobile body (1). An instruction to operate in cooperation is transmitted (R1-2). This instruction includes information that specifies the rental office (1), which is a common destination among the linked mobiles. In response to the instruction, the moving body (2) also starts moving toward the rental office (1).

The mobile body (1) transmits a request for a video conference to the mobile body (2) in the time until it merges with the mobile body (2) (R2, step S8 in FIG. 13). The mobile body (2) accepts the request. As a result, a TV conference is started between the cooperative mobile bodies (mobile body (1) and mobile body (2)).

When the TV conference is started, the destination setting unit 406 of the mobile body (1) determines the communication band required for communication with the nearest base station 800 in order to carry out the TV conference based on the communication band information 316. (R3). For example, the destination setting unit 406 determines that, for example, 5 MB / sec of the communication band of the nearest base station 800 is used before the start of the TV conference based on the communication band information 316, and uses it for the TV conference. The communication band is specified, and for example, 8 MB / sec is determined as the required communication band from the total of these (R3, step S9 in FIG. 13). The wireless communication information acquisition unit 409 of the mobile body (1) receives the communication band information (communication traffic 93, 94) of the management server 700 and the nearest base station 800 from polling at regular intervals (step S10 in FIG. 13).

The destination setting unit 406 determines whether the communication state between the mobile body (1) and the nearest base station 800 satisfies a predetermined condition while moving along the route to the destination (step S14 in FIG. 13). That is, it is determined whether or not the nearest base station 800 of the route can provide the required communication band described above.

For example, the destination setting unit 406 calculates the GPS position of the route to the destination from the map data, searches the radio base station DB803 of the management server 700 based on the calculated GPS position of the route, and uses the search result as the result of the search. Based on this, all base stations 800 having the closest position (GPS position 92) to the GPS position of the route are specified. The destination setting unit 406 reads the communication traffic 93,94 of all the specified nearest base stations 800 from the radio base station DB803 of the management server 700, and from the read communication traffic 93,94, each nearest base station 800 Calculate the available communication band you have. The destination setting unit 406 compares the calculated available communication band of each nearest base station 800 with the required communication band (for example, 8 MB / sec described above), and based on the comparison result, all the nearest base stations. When it is determined that the available communication band of the station 800 is equal to or higher than the required communication band, the communication state between the mobile body (1) and the nearest base station 800 is a predetermined condition when moving the route to the destination. It is determined that the condition is satisfied (YES in step S14). In this case, the destination is not reset (changed), and the process returns to step S10.

On the other hand, when the destination setting unit 406 determines that the available communication band of one or more base stations 800 among the nearest base stations 800 of the route is less than the required communication band based on the result of the above comparison. That is, when it is determined that the communication state does not satisfy the predetermined condition (NO in step S14), the destination resetting process is performed and the destination is changed (R4-2). Since this destination resetting process is the same as the process described in (T4-2) above, the detailed description will not be repeated.

In this destination resetting process (steps S19, S21, S23 in FIG. 13), the current position information is received from the moving body (2) which is a cooperative moving body (R4-1, step S17 in FIG. 13) and received. The current location information is used to determine one or more candidates for the destination. In the above destination resetting process (T4-2), the destination setting unit 406 determines whether the communication state satisfies a predetermined condition based on the communication speed for the route to each candidate's destination. However, in the case of FIG. 12, the destination setting unit 406 determines whether the communication state satisfies a predetermined condition for the route to each candidate destination based on the available communication band of the nearest base station 800 of the route. To judge. The destination setting unit 406 transmits a notification of the changed destination determined by the destination reset process to the moving body (2) (R4-3). For example, the destination setting unit 406 determines the changed destination as the rental office (2).

The moving body (1) and the moving body (2) set the changed destination (rental office (2)) in the destination information 315 (steps S25 and S29 in FIG. 13), and head toward the changed destination. Move (R5, steps S27 and S31 of FIG. 13).

In the cases of FIGS. 10 and 11, the process of resetting the destination by the destination setting unit 406 is when there is a change in the communication state due to an external factor (traffic congestion, existence of a tunnel, etc.) that occurs in the route. In the cases of FIGS. 12 and 13, when the communication band required by the mobile body (1) changes, the destination setting unit 406 performs the destination resetting process. It will be started.

According to FIGS. 12 and 13, when a user performs a moving work in a moving body, it is possible to provide a communication state that satisfies a predetermined condition with respect to the work.

The sequences of FIGS. 12 and 13 have been applied to the case where the moving body (1) merges with the moving body (2) at the destination with the destination as the merging point, but the application case is not limited to this. For example, in the case where only the mobile body (1) is moving to the destination, when the telephone conference or the TV conference is started, the destination is re-established so that the determined required communication band can be used. The setting process may be carried out.

Further, in the destination resetting process, the destination setting unit 406 may determine the changed destination by the combination of the communication speed and the communication band. Further, even if the destination setting unit 406 starts the destination setting process according to the combination of the change in the communication speed of the nearest base station 800 of the route to the destination and the change in the communication band required for the mobile body. Good.

<J. Changing destination setting conditions by task or schedule>
In FIGS. 10 to 13, when the changed destination is determined from one or a plurality of destination candidates in the destination resetting process, the destination setting unit 406 is performed in the moving body (1). The changed destination may be determined according to the work or the user's schedule 82.

For example, in the case of FIG. 10, the user of the mobile body (1) is working by using the local file provided by the user terminal 371, and wireless communication with the base station 800 does not occur. Further, the schedule 82 of the user of the mobile body (1) does not schedule a meeting during movement. It is assumed that the user of the mobile body (2) has a conference call scheduled from 13:00 to 14:00 on Schedule 82. In this case, the destination setting unit 406 determines that it is not necessary to secure the communication speed in the route on which the mobile body (1) moves, and there is no problem even if the non-communication route portion is included. On the other hand, the destination setting unit 406 of the moving body (2) calculates the predicted points from 13:00 to 14:00 on the route to the candidate destination, and predicts even if there is a tunnel on the route. If the point does not correspond to a non-communication point such as a tunnel, the destination setting unit 406 does not exclude the destination from the candidates.

In the present embodiment, the mobile device 30 performs the process for resetting the destination, but even if the information processing devices such as the management server 700, the user terminal 371, and the mobile terminal 379 perform the process. Good.
