DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.
[0015]
FIG. 1 is a diagram illustrating an overall configuration of an electronic mail system including an electronic mail server apparatus according to an embodiment. The information center 10 which is an electronic mail server device of the present embodiment includes a first electronic mail server 12 which is a first electronic mail processing means for the mobile terminal 30 and a second electronic mail for general terminals such as offices and homes. A second e-mail server 14 as processing means is provided. The first e-mail server 12 performs e-mail processing in response to access from the mobile terminal 30. That is, an electronic mail exchanged using mobile communication by access from the mobile terminal 30 is handled. The first memory 16 connected to the first e-mail server 12 stores e-mail accessed from the mobile terminal 30. On the other hand, the second e-mail server 14 handles e-mail exchanged by normal wired communication. The second memory 18 connected to the second e-mail server 14 stores e-mail for general terminals. A map database 20 is connected to the first and second electronic mail servers 12 and 14.
[0016]
A communication server 22 is connected to the first e-mail server 12. The communication server 22 controls communication with the outside and is connected to the mobile terminal 30 via the mobile communication line 28. The mobile communication line 28 includes a public telephone line, a radio base station, and the like, and a mobile terminal is connected via the radio base station. The second electronic mail server 14 is connected to a WWW server 24 that manages Internet homepages. The second electronic mail server 14 and the WWW server 24 are connected to the Internet 42 via the gate 26.
[0017]
The mobile terminal 30 has a mobile phone 32, and this mobile phone 32 is connected to a public telephone line via a wireless base station by wireless communication. Therefore, communication between the mobile terminal 30 and the information center 10 becomes possible by making a call to the information center 10 using the mobile phone 32. An ECU 34 is connected to the mobile phone 32. The ECU 34 is connected to a display 36 for displaying as an output unit and an input unit 40. The input unit 40 includes normal operation buttons and the like, but mainly uses a touch panel formed on the front surface of the display 36. Accordingly, various inputs can be made by touching the display 36 with various buttons and keys displayed on the display 36. It is also preferable to use a voice recognition device. Further, it is also preferable to provide a speech synthesizer or a speaker as an output device and perform a process for reading out an e-mail.
[0018]
An Internet 42 is connected to the gate 26, and a provider's e-mail server 46 is connected to the Internet 42 via a gate 44. Then, a general terminal 48 in the office or home is connected to the electronic mail server 46 of the provider via a public telephone line. Accordingly, the general terminal 48 is connected to the information center 10 via the Internet 42.
[0019]
Next, the exchange of electronic mail in such a system will be described. First, when an electronic mail message is sent from the mobile terminal 30 to the general terminal 48, the user operates the input unit 40 and makes a call to the information center 10 using the mobile phone 32. Thereby, the mobile terminal 30 and the information center 10 are connected. Here, the first electronic mail server 12 is connected to access to the information center 10 using the mobile communication line 28.
[0020]
This recognition is performed based on the caller's telephone number. That is, it recognizes whether it is a mobile telephone apparatus such as a cellular phone by the telephone number. In the information center 10, the telephone number to the first electronic mail server 12 and the telephone number to the second electronic mail server 14 may be set differently. Further, when connecting via the Internet 42, it may be connected to the second mail server 14, and when a direct telephone call is made via a public line, it may be connected to the first electronic mail server 12. Further, it may be registered whether or not the mobile communication is performed according to the user ID, or it may be selected whether to connect to the first or second e-mail server 12 or 14 in the connection procedure. Good.
[0021]
In the case of a telephone call from the mobile terminal 30, the mobile terminal 30 is connected to the first electronic mail server 12 through the communication server 22 as described above. Then, the mobile terminal 30 transmits an e-mail created in advance to the information center 10.
[0022]
The transmitted e-mail has a configuration as shown in FIG. That is, it consists of a mail title, type (a reply, CC, TO, etc.), destination, mail text, and position data. The e-mail is input using the input unit 40.
[0023]
Here, the e-mail includes position data. This position data is input using a navigation device mounted on the vehicle. That is, a map screen is displayed on the display 36 using the data of the map database 38. In this screen, the position data (latitude, longitude) is captured by inputting the position with the cursor and attached to the e-mail. For example, in the map display as shown in FIG. 3, when the target facility is clicked, position data including the latitude and longitude of the target facility is input.
[0024]
The e-mail sent from the mobile terminal 30 is received by the first e-mail server 12 and stored in the first memory 16 as it is. On the other hand, this e-mail is also supplied to the second e-mail server 14. The e-mail is stored in the second memory 18. At this time, map graphic data is created from the position data using the map data in the map database 20. That is, the position data received from the mobile terminal 30 indicates latitude and longitude. Therefore, based on this position data, the surrounding map data is read from the map database 20, and a mark is added to a point specified by the position data to create map graphic data. For example, the graphic data is as shown in FIG.
[0025]
Therefore, when the information center 10 is accessed from the mobile terminal 30, the first electronic mail server 12 responds, and when downloading of the electronic mail addressed to the terminal is requested, the information shown in FIG. The same email message data is provided. On the other hand, when there is an access from a general terminal 48 at home or office, the second e-mail server 14 responds, and when download of e-mail addressed to that terminal is requested, as shown in FIG. An electronic mail containing map graphic data instead of the position data is provided.
[0026]
Further, in response to a download request from the mobile terminal 30, an e-mail including the position data stored in the first memory 16 is supplied to the mobile terminal 30 as it is. Therefore, this communication is a short-time communication using a relatively small amount of data. The mobile terminal 30 refers to its own map database 38 based on the position data of the received message data, and displays the position specified by the position data together with the map display on the display 36. On the other hand, the general terminal 48 at home or office receives map graphic data and displays it on the display 36. Therefore, appropriate data can be provided according to the type of terminal. Further, since the information center 10 is provided with the e-mail servers 12 and 14 separately, a quick response can be performed.
[0027]
In particular, when accessing from the mobile terminal 30, there are various restrictions. For example, there is a restriction that communication is interrupted due to a communication failure or the memory capacity cannot be increased. Therefore, as described above, it is very effective to shorten the communication time by exchanging position data. Further, for access from the mobile terminal 30, data on the free memory capacity in the mobile terminal 30 is obtained, and an e-mail to be transmitted is selected according to this capacity, or only a list is transmitted. Is preferred. According to the information center 10 of the present embodiment, the first electronic mail server 12 is a server dedicated to the mobile terminal 30, and such processing can be appropriately performed.
[0028]
In the configuration of FIG. 1, the first and second e-mail servers 12 and 14 and the first and second memories 16 and 18 are physically separated. Can be combined into one. In this case, the data stored in the memory may have one overlapping portion, and the data to be read may be controlled depending on which function is used for reading. The servers themselves may be separated and only the memory may be collected.
[0029]
Furthermore, in the mobile terminal 30, various program data, graphic data, and the like are often not decipherable. Therefore, the first e-mail server 12 deletes the program data and the like when attached, and attaches only the “present” and “none” information of the attached file to the first memory 16. Remember it. Then, in response to a download request from the mobile terminal 30, those obtained by deleting these attached materials are provided. On the other hand, the second electronic mail server 14 stores the attached material as it is in the second memory 18 and provides it to the general terminal 48.
[0030]
In the above example, all e-mails are stored in the two memories 16 and 18, but may be registered in advance and stored in both only the user. That is, depending on the user, it is registered whether one or both types of terminals (general terminals and mobile terminals) are used, and only when both types of terminals are used, two types of data are stored. Store in memory.
[0031]
Further, when the WWW server 24 is accessed via the Internet 42, an electronic mail addressed to itself can be viewed after authentication in communication with the WWW server 24. Further, the WWW server 24 transmits an e-mail having an address of the Internet 42 to the e-mail server 46 of the provider. The transmission data is basically the same as that transmitted by the second electronic mail server 14.
[0032]
Here, the mobile terminal 30 may specifically be an in-vehicle terminal mounted on a vehicle, or a mobile computer such as a portable information terminal or a notebook computer.
[0033]
Moreover, although the example in which data is exchanged between the first e-mail server 12 and the second e-mail server 14 has been described above, the present invention also applies to the case where data is exchanged between the first e-mail server 12 and the WWW server 24. This is a category. In this case, when information with position data is included in the WWW home page data and the home page data is to be viewed from a mobile terminal such as an in-vehicle terminal or a portable information terminal, the information in the acquired home page is transferred to the mobile terminal. It can be displayed on a mobile terminal linked to an information map.
