[0049]
FIG. 4 is a flowchart of the advertisement setting process. In the mobile device 10, the control means 11 accepts an advertisement necessity / unnecessary setting from the user (S1). The setting may be accepted by, for example, displaying a selection menu indicating whether an advertisement is necessary / unnecessary on the display unit 14 in accordance with the operation of the input unit 13 by the user, and allowing the user to select. Next, the control means 11 displays a setting confirmation on the display means 14 and accepts a confirmation input from the user (S2). As a result, if the setting is incorrect, the setting returns to S1 again. On the other hand, if the setting is correct, the necessary / unnecessary advertisement setting content is transmitted from the communication means 17 to the center device together with the preset user ID (S3). The user ID is stored in the memory 16 in advance. Next, in the center device 20, the control means 21 that has received the setting information for advertisement necessity / unnecessary and the user ID of the transmission source connects to the accounting DB 29 and updates the advertisement necessity / unnecessary data of the corresponding user (S 4). S5).
[0050]
FIG. 5 is a flowchart of the route request process. In the mobile device 10, the control means 11 accepts input of information related to the destination from the user (S11). The information regarding the destination includes the address and telephone number of the destination. For the address, for example, a prefecture name, city name, etc. are selected from the menu and input, and an address is input from the numeric keypad of the input means 12. The telephone number is input from, for example, a numeric keypad of the input unit 12. Subsequently, the control unit 11 receives an input of a motive (desired to be performed at the destination) from the user toward the destination (S12). Motivation is input by selecting from a menu, for example. Subsequently, the control means 11 calculates the current position of the mobile body based on the output of the current position detection means 12 (S13), and the center device 20 together with the user ID and the information on the destination, the motivation, and the current position information. (S14).
[0051]
Next, in the center device, the control means 21 that receives these pieces of information (S15) executes a route search process (S16) from the current position of the moving body to the destination and an advertisement search process (S17). .
[0052]
The route search process is executed as follows. The control means 21 searches the destination DB 27 using the information (phone number or address) relating to the destination sent from the mobile device 10 as a search key, and acquires the location information of the destination. A route search is executed based on the location information of the destination, the current location information of the mobile unit received from the mobile unit 10 and the data in the route search DB 25. Here, the center apparatus 20 acquires real-time information such as accident information and traffic jam information from the outside. Acquisition of real-time information is performed via the network 40, for example. In route search, an optimum route is searched in consideration of this real-time information.
[0053]
In addition, the advertisement search process is executed as follows. First, the control means 21 confirms whether or not the user who has requested the route search desires to transmit an advertisement by referring to the advertisement necessity / unnecessary setting in the accounting DB 29. As a result, if the advertisement is not desired, the process is terminated. On the other hand, when an advertisement is desired, the following processing is executed. That is, first, the destination DB 27 is searched using information (phone number or address) about the destination sent from the mobile device 10 as a search key, and for example, the name of the destination is acquired. Next, the corresponding advertisement information is searched from the advertisement database using the destination name and the motivation information received from the mobile device 10 as search keys. For example, in FIG. 2, when the destination “XX amusement park” and the motivation “eat” are specified, advertisement “XX restaurant / tomato spaghetti” in or around the amusement park premises is used as advertisement information. "Set / 800 yen" is searched. Here, the advertisement information may be accompanied by image data or video data.
[0054]
Next, the control means 21 searches the map DB 24 for map data of the surrounding area of the current position based on the current position information of the moving body, and also based on the result of the previous route search. Guidance data necessary for route guidance in the area is retrieved from the guidance DB 26, and the destination data of the destination designated this time is retrieved from the destination DB 27 (S18). Then, the advertisement information and map data searched in S17 and S18 and the portion of the route data searched in S16 within a certain area from the current position of the mobile are transmitted to the mobile device 10 collectively. (S19).
[0055]
The control unit 11 of the mobile device 10 that has received this transmission (S21 in FIG. 6) stores the received data in the memory 16 and displays the received advertisement information on the display unit 14 (S23). Further, route guidance processing within a certain area is executed from the current position based on the sent map data, guidance data, route data, etc. (S22). Then, when the mobile body travels along the route and reaches the end point of the route in the certain area received first, the control unit 11 requests the center device 20 to transmit the next route (S24). In response to this request, the mobile device 11 obtains the current position of the mobile device calculated based on the output of the current position detection means 12 and the destination data (destination location information) received in the memory 16 earlier. Send to.
[0056]
Upon receiving this request, the control means 21 of the center device 20 starts from the current position based on the received destination and current position information, real-time information updated at this time, and information in the route search DB 25. A route search to the destination is executed (S25). Further, as in S18 of FIG. 5, map data and guidance data within a certain area are read from the DB from the current position of the moving body (S26), and transmitted from the current position together with route data within the certain area to the moving body device 10. (S27). Thereafter, the processing from S21 is repeated. In response to the second and subsequent route search requests (S24), the control means 21 of the center device 20 searches for new advertisement information in the same manner as in S17, and in S27, along with the route data, map data, and guidance data described above. It may be transmitted to the mobile device 10.
[0057]
Next, FIG. 7 is a flowchart of packet transmission processing executed by the control means 21 of the center apparatus 20. Each time the control unit 21 transmits a packet to the mobile device 10, the control unit 21 performs a billing process according to the transmission amount of the packet for the user of the transmission destination (S31, S32). The billing process is performed as follows. The control means 21 searches the charging DB using the ID of the user who transmitted the packet as a key, and confirms the advertisement necessity / unnecessary setting of the record of the corresponding user. Then, the amount obtained by multiplying the charge unit price corresponding to this setting by the number of transmitted packets is added to the value of the charge amount field of the user record. The billing amount is settled and reset at regular intervals. Further, when advertising information is transmitted to the user, an advertising agency fee is charged to a charging DB for each advertiser (not shown).
[0058]
Here, the various processes of the mobile apparatus and the center apparatus described above are processed by multitasking.
[0059]
Next, another embodiment will be described with reference to FIG. The system configuration is the same as in FIG. The user may select an advertisement by specifying a genre. In this case, the control means 11 of the mobile device 10 receives the advertisement genre designation and the sub-genre designation from the input means 13, and transmits this designation to the center apparatus 20 (S41, S42, S43). The genre and sub-genre can be input by downloading a list of genres and sub-genres from the center device 20 to the memory 16 and allowing the display unit 14 to select a menu of genres and sub-genres by the user. It is done. Here, the designation of the sub-genre may be arbitrary.
[0060]
The control means 21 of the center apparatus 20 that has received the designation of the genre and sub-genre searches the advertisement DB 28 using the genre and sub-genre as search keys (S44, S45). For example, in FIG. 2, when the genre “concert” and the sub-genre “pops” are designated, “11/11/18: 00- / AAA concert” of xx amusement park is also searched as one of the advertising information. The In the main search, there is a possibility that a plurality of advertisement information having the same genre and sub-genre are searched. The control means 21 transmits the searched advertisement information to the mobile device 10 alone or together with other data such as map data, guidance data, and route data as in the previous embodiment (S45).
[0061]
The control means 11 of the mobile device 10 receives the sent advertisement information in the memory 16 and displays it on the display means 14. The display method may be a slide show format in which advertisements are switched every predetermined time if they are images, or scroll display if they are text advertisements. In addition, a list of advertisements may be displayed on the display unit 14 to allow the user to select.
[0062]
According to the embodiment described above, charging is performed according to the amount of information transmitted to the user. Therefore, the capital collected as sales of media such as DVDs and in-vehicle devices is referred to as an information fee for information distributed from the center device. It can be recovered in the form. On the other hand, the user of the mobile device can narrow down the advertisement information received from the center device to only the necessary advertisements according to the destination, motivation or genre. The inconvenience of being charged can be avoided. In addition, when the display of the advertisement is obstructive, the transmission of the advertisement information from the center device can be rejected by setting whether the advertisement is necessary or unnecessary. In this case, the operator of the center apparatus may reduce the advertising revenue from the advertiser. Therefore, the advertising revenue can be changed by changing the billing unit price for each user according to whether the advertising is required / not required by the user. It is also possible to compensate for this decrease.
[0063]
In addition to this, route data, map data, guidance data, etc. are transmitted to the mobile device only within a certain area from the current position of the mobile body. If all the route data from the current position to the destination, map data and guidance data of the entire process accompanying it are sent to the mobile device, if the mobile device leaves the route on the way, The transmitted map data, guide data, and the like are wasted, and the user has paid a useless information fee. However, as in this embodiment, if data is transmitted only to a certain area and the next data is transmitted whenever necessary, the waste of data can be minimized even if the route is departed on the way. This is highly beneficial for the user.
[0064]
Further, when sending the advertisement data, the necessary data out of other map data, guidance data, route data, destination data, etc. are sent together to the mobile device 10 so that it is dead in the data storage space of the packet. The probability of creating a space can be reduced, the ratio of the amount of information to the packet unit price can be increased, and there are high benefits for the user.
[0065]
As described above, according to this embodiment, it is possible to adjust the profit of the information provider and the profit of the user.
[0066]
Here, the present invention is not limited to the above embodiment. For example, a part of the DB of the center device may be held on the mobile device side. When the advertisement information is transmitted from the center device, the type of data transmitted together with the advertisement information is arbitrary. Further, only the advertisement information may be transmitted. The transmission of the route from the center device to the mobile device may be performed by transmitting all routes from the current position to the destination. A destination DB is provided in the mobile device, and the mobile device allows the user to select the name and motive of the destination, transmits the location information and motive of the selected destination to the center device, and searches the route on the center device side. An advertisement search may be performed. The billing amount may be larger when an advertisement is required than when it is not required. For example, it is a case where advertisement information selected according to a destination or motivation is considered information with high added value.
[0067]
【The invention's effect】
  The present inventionSince the charge amount corresponding to the amount of information is varied for each user according to whether the advertisement information is necessary / unnecessary, the user's profit can be adjusted.
