The input means 37 includes a touch pen, a jog dial, a keyboard, a micro switch, and the like. Interface 41
Performs interface processing to the internal bus 40 of various circuits and devices. Note that the audio output unit 38 and the position information acquisition unit 39 will be described later.

Next, FIG. 3 shows a block diagram of a hardware configuration of the server 15. CPU 50, ROM 51 and R
The function of the AM 52 is the same as that described above in the mobile terminal 10. The server 15 has a storage unit 56.
The storage unit 56 is a storage device that can store various programs and files, information and data including large-capacity images, and can read out the data as appropriate. These data and programs can be written to the RAM 52 as necessary to perform various types of information processing. The input means 55 is a keyboard,
It is constituted by a mouse, etc., and gives a command for causing the server 15 to perform various types of information processing. Interface 58
Performs interface processing to the internal bus 57 of various circuits and devices. The display unit 54 includes a CRT or an LCD, and displays characters, graphics, and images. The communication control unit 53 controls a communication function for transmitting and receiving data and the like via an external public communication network.

FIG. 4 shows an outline of the configuration of a communication network that enables data transfer between the portable terminal 10 and the server 15. The mobile terminal 10 is connected to the base station 11 by wireless communication by its PHS function. The base station 11 is an ISDN network 1 which is one of public networks.
2 is connected. On the other hand, the server 15 is connected to a LAN (local area network) 14 and
An access point 13 that provides a connection to the ISDN 12 is assigned to 4. As a result, a physical communication network is formed between the mobile terminal 10 and the server 15.

The functions of the portable terminal 10 and the server 15 according to the present invention will be described with reference to FIGS. When the user of the mobile terminal 10 captures a digital photograph through the camera input unit 34, information of the captured still image is stored in the RAM 33 as digital still image data. Once the still image data is written into the RAM 33, the CPU 31 of the mobile terminal 10 automatically or in response to an input command from the input unit 37 from the user, receives the input command from the wireless communication processing unit 36.
Makes a call to the access point 13, and the mobile terminal 10 and the server 15 form a physical communication network. CPU 31 via a physical communication network
Transfers the still image data to the server 15. Here, if the storage capacity of the RAM is equivalent to two still image data, the still image data shot each time one image is shot is stored in the server 1.
5, while the next still image can be photographed. The server 15 that has received the still image data stores the still image data in the storage unit 56 of the server 15.

Thus, using the communication network,
By transmitting and storing the captured still image data to the server 15, the portable terminal 10 may use the RAM 33 having the minimum capacity, and a new method for storing a large amount of large-capacity image data may be used. No RAM is required. Therefore, even in the case of a simple portable terminal device for which cost and reduction in size and weight are strongly desired, a large amount of still image data can be handled and stored while having the function of a digital still camera.

Here, by making the communication protocol used by the server 15 and the portable terminal 10 common, mutual transmission and reception of data becomes possible. Here, HTTP (HyperText Transfer Protocol) is used as this communication protocol.
By using l), data can be transmitted and received in the same operation method as a WWW browser such as Microsoft Explorer or Netscape Navigator manufactured by Microsoft in the United States, which is generally used today. HTTP defines a common procedure for transmitting and receiving hypertext. When data transmission and reception between the server 15 and the mobile terminal 10 are performed by HTTP, the mobile terminal 10 converts the image data into HTML (HyperText Markup Language) file data and transmits it to the server 15.

The communication protocol is an e-mail protocol such as SMTP (Simple Mail Transfer Protocol), which is conventionally known, and is commonly used by the portable terminal 10 and the server 15, so that the following new functions are provided. Have.

Conventionally, an e-mail created by the portable terminal 10 is temporarily transmitted by using a transmission instruction of an e-mail application program of the portable terminal 10.
The mail is transmitted to a so-called mail server which is a component of the server 15. The mail server transmits the stored e-mail to another portable terminal when there is an access for reading the e-mail from another portable terminal to be transmitted. Even when the still image data is attached to the e-mail and transmitted, the still image data obtained by the portable terminal 10 is stored in the conventional RAM 03 (FIG. 1) as necessary, and the stored image data is stored. Was read from the RAM 03 and attached to the electronic mail as binary data.

However, in the present invention, after the still image data obtained above is temporarily stored in the RAM 33,
The information is transmitted to the server 15 via the communication network. The server 15 stores the still image data in the storage unit 56. On the other hand, the mobile terminal 10 creates an e-mail according to the e-mail application program,
The e-mail is transmitted to the mail server via the communication network. At this time, the e-mail includes the address of the still image data to be attached and the name of the binary file. Therefore, when an e-mail is accessed from another information processing device such as a portable terminal, the mail server can transmit the still image data as binary attached data. By doing so, the number of still image data that can be handled depends on the storage capacity allocated to the mobile terminal 10 of the server 15 and the RAM 33 of the mobile terminal 10
Because it does not depend on the storage capacity of the user, a large amount of image data can be transmitted to another user who desires. In the above description, the mail server has been described as a component of the server 15, but it can be easily inferred that the present invention can be applied even when the mail server and the server 15 are connected via a communication network. right.

The storage means 56 stores the image data as described above, or in place of the image data, performs processing for receiving e-mail, facsimile and other information received by the portable terminal 10 for each portable terminal. Can be stored. The server 15 performs the process on behalf of the portable terminal 10 or mediates according to the stored processing content.

First, a case where an e-mail is received will be described as an example. The server 15 automatically transfers the e-mail from the user A to the portable terminal, and automatically responds to the e-mail from the user B with a reply message stored in advance in the storage unit 56 as a reply mail. The setting is registered so that the e-mail is transmitted and no response is made to e-mails from others. When receiving the e-mail, the server 15 analyzes the e-mail address of the sender and performs processing based on the registered processing contents. If the electronic mail is from the user A, the electronic mail is immediately transmitted to the registered portable terminal 10. On the other hand, if the email is from the user B,
Is returned to the user B with the absence message attached to the absence message stored in.

Next, a telephone addressed to the portable terminal 10 is sent to the server 15.
Will be described. The server 15 transfers the call from the telephone number of the user A to the portable terminal 10, and the telephone 15 from the user B or any other telephone number has the absence message stored in the storage unit 56 in advance. Registered to send messages. Where I
In the case of the SDN network, since there are two communication channels, one channel is used by the server and another user, and the other channel is used by the server 15 and the portable terminal 10, so that the telephone call from the user A can be used. Is transferred from the server 15 to the portable terminal 10 by using another channel of. On the other hand, if it is not possible to identify who the user B or the caller telephone number is from, the absence message is transferred. The above-described response processing of the server 15 can be similarly performed for a facsimile addressed to the mobile terminal 10. In the case of FAX, if the FAX protocol is used as the transfer protocol to the portable terminal 10, the FAX processing means must be provided in the portable terminal 10, and the throughput of the data transfer rate deteriorates. Further, when the user moves, the electric field strength decreases and F
There is a problem that AX cannot be received. Therefore, the FAX received by the server 15 is once converted into a binary mail by the server 15 and transmitted to the mobile terminal 10, so that the same processing as the electronic mail can be performed. Furthermore, not only telephone, e-mail, fax, but also information registered by the user himself,
For example, if the above-described method is used for the schedule management information, the user having the mobile terminal 10 can be notified anytime and anywhere.

Next, a case where multimedia information such as music is downloaded from the server 15 will be described. In this case, the portable terminal 10 is used as a device for performing audio reproduction by another application program stored in the ROM 32. Therefore, the portable terminal 10 has a new voice output unit 38 as shown in FIG. Here, the audio output unit 38 has a function of expanding a physical sound source device such as a speaker and compressed music data, and reproducing an audio signal from the sound source and pitch data of the music data. On the other hand, the storage means 56 of the server 15
Here, the apparatus comprises various devices for recording and reproducing music, such as an optical disk for storing compressed music data to be transmitted to the portable terminal 10 and a recording and reproducing device of a data streamer system, or a combination of them. Specifically, it refers to a medium such as a so-called compact disk (CD: trademark), a mini disk (MD: trademark), and a tape recorder. Further, the server 15 has the media information for specifying the medium and the music information stored for each medium, so that the music data stored in the storage unit can be identified. It should be noted that the music information is, specifically, in the case of an MD or a CD-EXTRA (a CD-ROM extended so as to be able to record music and video), these music information are stored for management. , Which is obtained by reading the text information by the server 15. In the case of a medium such as a CD or a tape in which music titles cannot be managed, the server 15 does not have music information.

On the other hand, the RAM 33 of the portable terminal 10 temporarily stores the music data stored in the storage means,
Under the control of the PU 31, the audio output means 38 reproduces music based on the stored music data.

FIG. 5 is a schematic diagram showing the flow of processing between the portable terminal 10 and the server 15 up to the music reproduction. First, the mobile terminal 10 performs a line connection process with the server 15 to acquire music data stored in the storage unit (S700). When the line is connected, the request for acquiring the list information of the media and music information described above is transferred to the server (S701). Upon receiving the list information acquisition request, the server 15 transmits text information for identifying the music title recorded on the CD-EXTRA or MD to the CD-EXTRA or the MD.
Read from EXTRA or MD, along with media information,
The information is converted into information that can be processed by the mobile terminal 10 and transmitted to the mobile terminal 10 (S702). If there is no music information, only the media information is transmitted to the portable terminal 10 (S702). Here, the information that can be processed by the mobile terminal 10 is, for example, information according to HTTP. When data transmission and reception between the server 15 and the mobile terminal 10 are performed by HTTP, the server 15 converts media information and music information into the format of the HTTP data. The converted media information and music information are transmitted to the mobile terminal 10 so that the user of the mobile terminal 10
By displaying the media and music information managed by 5 on its display means 35, the contents can be confirmed. Further, when one or a plurality of music titles or media to be requested is selected from the input device by the input unit 37, the mobile terminal 10 transmits a specific music data or media acquisition request to the server 15 (S70).
3). In response to the acquisition request, the server reads the specified one or a plurality of music data or the first music data of the medium from the storage unit, and transmits the read music data to the mobile terminal 10 (S704). The music data is received by the portable terminal 10 and stored correctly in the RAM 42, and then the line is disconnected (S705). If all the music data cannot be recorded in the RAM 42 due to its capacity, the next music data to be reproduced is overwritten on the recording of the music data after the music reproduction is completed, so that the music reproduction is performed without interruption. It can be performed. In this case, new music data to be reproduced is sequentially transmitted from the server 15 to the portable terminal 10 each time (S704 '). Note that the method for the mobile terminal 10 to select a music title and receive necessary music data by using HTTP is to use a normal WWW browser, select a portion linked to a file, and apply This can be performed in exactly the same way as the method of reading a file.

Next, a case where map data required by the navigation function is downloaded from the server 15 will be described. In this case, the mobile terminal 10 is connected to another navigation application stored in the ROM 41.
It is used as a device for giving instructions on a map by a program. For this reason, the portable terminal 10 has a new position information acquisition unit 39 as shown in FIG.

The position information obtaining means 39 will be described.
There are various specific technical means for acquiring position information at present. However, the portable terminal 10 having a digital telephone function such as PHS can roughly know its current position by knowing the ID number of the base station 11 (FIG. 4) at the time of telephone communication. For example, in PHS, each base station 11
Is located so as to be able to communicate with any of the base stations at any position, and specifically, as shown in FIG. 6, an area having a radius of about 100 meters. A base station 11 is provided for each. And
By setting it as a jurisdiction area that can be managed by the base station, the base station can determine that the mobile terminal 10 with which it is wirelessly communicating exists in the jurisdiction area of the base station. In general, a receiving base station that has received the strongest electric field strength of a radio wave transmitted from the mobile terminal 10 among the base stations determines that the mobile terminal 10 is located in an area controlled by the receiving base station. Is done. Further, each base station 11
, An identification number for identifying the base station (hereinafter, referred to as a base station ID) is assigned in advance. Therefore,
The location information acquisition unit 39 of the mobile terminal 10 obtains the ID number of the base station performing the wireless communication, so that the mobile terminal 10 itself determines which jurisdiction area the mobile terminal 10 is currently in. Can be. As described above, the position data of each base station is fixed and known, and the position of each information terminal 10 can be easily known by assuming the current position of the mobile terminal 10 as its receiving base station position. It is.

On the other hand, the server 15 stores various information such as sports and other entertainments in addition to map information and information such as stores and business contents shown in the map in its storage means 56. It has multimedia information. The map information includes the ID of each base station at the position
(Ie, the base station indicated by the base station ID is mapped on the map information), and by specifying the base station ID, a map around the base station and a map around the base station can be obtained from the map information. Information such as stores on the map can be searched.

Hereinafter, the flow of processing between the server 15 and the portable terminal 10 until the multimedia information is acquired by the portable terminal 10 will be described with reference to FIG. First, when acquiring multimedia information including map information, the mobile terminal 10 performs a line connection process with the server 15 (S900).
After the line connection processing, a multimedia information acquisition request indicating which area of the map and multimedia information the user wants to acquire is transmitted to the server 15 (S901). The multimedia acquisition request includes the base station ID, which is the location information acquired by the location information acquisition unit 39 of the mobile terminal 10 described above, or the multimedia information desired by the user through the mobile terminal 10. Contains specified data to be specified. The server 15 that has received the base station ID or the designated data reads out the necessary multimedia information from the storage unit 56 based on the base station ID or the designated data, and sends it to the portable terminal 10 (S902). Since the multimedia information downloaded to the RAM 33 of the mobile terminal 10 is displayed on the display means of the mobile terminal 10, the user of the mobile terminal 10 can obtain information such as a map near the place where the user is located or a store in the area. In addition, other multimedia information obtained by the specified data can be viewed. As described above, the mobile terminal 10 arbitrarily receives only information necessary for performing navigation from the server 15 and does not need to perform communication with the server 15 during navigation. There is also the effect that there is no charge. Note that the mobile terminal 10
The method of selecting multimedia information requested by the mobile terminal 10 and receiving necessary music data by using the HTTP described above as an example of a protocol for transmitting and receiving multimedia information between the server and the server 15 is usually WWW
Using a browser, a part linked to a file is selected, and the file can be read out in exactly the same manner as the method of reading out the file. In this example, the position information obtaining means 39 obtains the base station ID of the PHS and specifies its position.
System) It is also possible to obtain information on the vicinity of the place by specifying the position using the calculation means. GPS
The calculating means receives and demodulates positioning signals transmitted from a plurality of low-orbit satellites, and calculates and calculates the longitude and latitude of the current position. Therefore, when the mobile terminal 10 has the GS
By having the antenna for P, the reception circuit, the demodulation circuit, and the arithmetic circuit, the server 15 can transmit its own longitude and latitude to the server 15. At this time, the map data and related information around the position can be transmitted to the mobile terminal 10.

[0030]

As described above, the image data acquired by the portable terminal or the multimedia information to be used by the portable terminal is stored by the storage means on the server side, and the portable terminal needs the data for processing. By transmitting the data to the storage means or receiving the data from the storage means every time, the mobile terminal only needs to have the minimum storage capacity, and the hardware of the mobile terminal is reduced and the large-capacity data processing is performed. And now, by expanding its server, it is possible to handle almost unlimited information on its mobile device. Furthermore, by providing processing according to each user on the server side,
