Description

  The present invention is a portable wireless communication terminal capable of performing data communication such as facsimile communication and e-mail communication using a portable wireless communication network such as for PHS (Personal Handyphone System) and mobile phone. About.

  Recently, with the spread of portable wireless communication terminals such as PHS terminals and the increase in transmission speed of data communication using these portable wireless communication terminals, various data such as text data and image data can be used in addition to voice communication. Wireless data communication services that enable wireless communication have attracted attention.

  For example, in an example using a PHS terminal, data communication is possible at a transmission rate of 32 kbit / s, and a transmission rate of 28.8 kbit / s or 33.6 kbit / s when a modem is used on an analog telephone line. The transmission speed is about the same as that of a second, and an environment in which e-mail exchange, facsimile communication, and the like can be performed from the outside by a portable wireless communication terminal has been established.

  By the way, when a portable wireless communication terminal is provided with a so-called data communication function such as electronic mail communication or facsimile communication and a telephone function for performing voice communication, the user himself has to switch which function is used.

  For example, a switch button switch for switching between a data communication function and a telephone function may be provided in the portable wireless communication terminal so that the data communication function and the telephone function are switched according to the purpose at the time of use.

  However, it is troublesome to switch between the data communication function and the telephone function one by one when using the portable wireless communication terminal. In addition, the intention to switch to the telephone function due to an erroneous operation or foreign object touching the switch button switch has been switched to the data communication function, and no telephone call has been made, and vice versa. The phone function has been switched to, but there may be inconveniences such as inability to receive e-mail and facsimile information.

  In addition, in order to receive e-mail and facsimile information and display the information easily for the user, it is desirable that the display area of the display screen for displaying the information is as large as possible.

  However, when various operation keys are provided on the same surface as the display screen of the main body, the display screen is reduced accordingly. For example, in order to function as a telephone terminal, a speaker (handset), a display (display screen), operation keys such as a dial key, a microphone (transmitter) on the same surface (front surface) of the casing of the portable wireless communication terminal ) Etc., and there is a limit even if it tries to enlarge the display screen.

  In other words, if the display area of the display screen is to be used largely, the part other than the display screen must be reduced and the display area must be increased, or the casing of the portable wireless communication terminal itself must be increased. However, in the former case, for example, when the speaker or the operation key is made small, it may be difficult to hear the other party's voice, the dial operation is difficult to make mistakes, and the usability may be deteriorated. In addition, when the casing is enlarged, the portability is impaired, and the original function of the portable wireless communication terminal that can be used even when away from home is impaired.

  In view of this, a portable wireless communication terminal is connected to a portable personal computer with a cable to display received information on a display screen of the personal computer. However, in that case, it is necessary to carry the portable wireless communication terminal and the portable personal computer at the same time, which is inconvenient.

  In view of the above points, the present invention has a function as a telephone terminal and a data communication function that enables e-mail exchange, facsimile communication, and the like without impairing portability, and is easy to use. A wireless communication terminal is provided.

This is a multi-function device having a function as a PDA (Personal Digital Assistant).

  The portable wireless communication terminal of this embodiment functions as a PDA, and when performing facsimile communication or e-mail communication, it is connected to one common server in a contract relationship through a network, and the portable wireless communication terminal Information transmission from the communication terminal to the desired partner and reception of information addressed to itself are performed by the cooperation of the portable wireless communication terminal and the server device.

[Description of network system]
First, a network system formed by using the portable wireless communication terminal of this embodiment will be described.

  FIG. 5 is a diagram for explaining a conceptual configuration of a communication network system formed by using the portable wireless communication terminal according to the embodiment of the present invention. In FIG. 5, 1 is a contract relationship with a common server device. In this embodiment, the portable wireless communication terminal 2 is a common server device. A plurality of portable wireless communication terminals 1 and a common server device 2 are a network 3 for portable wireless communication terminals, and a dedicated backbone connected to the network 3 through one to a plurality of access points 4. Connected through the network 5.

  Other mobile wireless communication terminals that are not contracted with the common server device 2 are also connected to the mobile wireless communication terminal network 3, but can receive a service of cooperative processing of the common server device 2 as described later. The portable wireless communication terminal is only the portable wireless communication terminal 1 that has been previously contracted with the common server device 2. In order to avoid confusion with portable wireless communication terminals that do not have a contract relationship with the common server device 2, in the following description, portable wireless communication terminals that have a contract relationship with the common server device 2 will be referred to as member terminals.

  Each of the plurality of member terminals 1 and other portable radio communication terminals of the same type is wirelessly connected to a radio base station 6 provided in a predetermined area unit in consideration of, for example, a radio wave reachable range. For example, an optical cable is used in the network 3 for portable wireless communication terminals such as a connection between the wireless base stations 6.

  A network management server device 7 that manages the network 5 is connected to the dedicated backbone network 5. The network management server device 7 manages so-called routing between the common server device 2 and the member terminal 1. Therefore, the common server device 2 can be positioned as one of the terminal devices connected to the dedicated backbone network 5 when viewed from the routing management on the network management server device 7. In this case, the network management server device 7 is also connected to the Internet 8.

  In this embodiment, the network management server device 7 is also directly connected to the common server device 2, and the access history from the member terminal 1 to the common server device 2 is stored in the network management server device. 7 to the common server device 2. In other words, in this embodiment, the common server device 2 is configured to perform comprehensive member management such as charging log collection of the member terminal 1.

  That is, in the case of this embodiment, the member terminal 1 has a contract relationship with the common server device 2 and does not have a contract relationship with the network management server device 7. The common server device 2 entrusts management of the member terminals 1 over the network connection to the network management server device 7, and there is a contract relationship between the common server device 2 and the network management server device 7. . Therefore, the common server device 2 can be connected to other dedicated backbone networks and their network management server devices with the same relationship as the above-described dedicated backbone network 5 and its network management server device 7. .

  In this embodiment, when viewed from the common server device 2, a specific dedicated backbone network is assigned to each member terminal 1, and access to the common server device 2 from each member terminal 1 is as follows: The management is always performed through the dedicated backbone network allocated for the member terminal. However, when viewed from the member terminal 1, the contract relationship between the common server device 2 and the network management server device 7 is completely different. Since it is irrelevant, the member terminal 1 simply accesses only the common server device 2 and is managed only by the common server device 2.

  According to such a network management configuration, for example, by allowing the common server device 2 to have all the service functions of the individual network management server devices 7, the user of the member terminal 1 can manage each individual network management device. In order to receive various services provided by the server device 7, various contracts that the common server device 2 has only by creating a contract relationship with the common server device 2 instead of making a contract with each network management server device 7. It is very convenient to be able to receive services.

  The common server device 2 is connected to the public line network 9, and the member terminal 1 communicates with a communication terminal 10 such as a facsimile terminal or a personal computer connected to the public line network 9 as will be described later. It has a function to enable data transmission / reception.

  Further, in this embodiment, the common server device 2 includes a storage unit that is a part of a database of provided information in order to perform an information providing service for the member terminal 1. In addition, the common server device 2 is connected to the content providing device 11, and obtains the information remaining from the database of information provided to the member from the content providing device 11 and provides the information to the member terminal 1. To do.

  The content providing device 11 is provided by a providing company having unique provision information, and provides the information to the member terminal 1 through the common server device 2 through a contract with a service company having the common server device 2. is there. Although only one content providing device 11 is shown in FIG. 5, there are of course cases where a plurality of content providing devices 11 are connected to the common server device 2.

  The common server device 2 and the content providing device 11 may be connected through a dedicated line or through a network such as the Internet.

  In the case of this embodiment, the information from the content providing apparatus 11 connected to the common server apparatus 2 through these dedicated lines or networks is received when the common server apparatus 2 requests the information provision from the member terminal 1. The content providing apparatus 11 is accessed and acquired, and is provided to the requested member terminal 1.

  Information from the content providing device 11 may be acquired as needed and stored in the internal memory unit of the common server device 2 so that the storage content of the internal memory unit is kept up-to-date.

  In this embodiment, the common server device 2 is connected to one to a plurality of content providing devices 11, collects information from these content providing devices 11, and provides it to the member terminal 1. Therefore, the member terminal 1 does not need to make a contract with each content providing apparatus 11, and the common server apparatus regardless of the format of information from the plurality of content providing apparatuses 11. 2 can receive necessary information.

  As a method of providing content to the common server device 2 by a provider having unique provision information, the content provider is not connected to the common server device 2 through a dedicated line or a network as described above. There is also an aspect in which a recording medium such as a CD-ROM is provided to the common server device 2 and stored in the storage unit of the common server device 2.

  In this embodiment, when a contract between the user of the portable wireless communication terminal 1 and the company that owns the common server device 2 is made, the portable wireless communication terminal 1 becomes the member terminal 1 as described above. For example, the purchase of the member terminal 1 by the user can be a contractual relationship with the common server device 2.

  That is, when a user purchases a portable wireless communication terminal as a member terminal 1, the member terminal 1 has address information of the common server device 2 through a specific dedicated trunk network for each terminal as described above. It is given in advance and stored in a non-volatile memory. The nonvolatile memory also stores identification information indicating that the member terminal 1 is a member terminal that has a contract relationship with the common server device 2. However, the registration of writing to the member terminal 1 such as the address of the common server device 2 may be performed by a terminal salesperson or a purchaser at the time of purchasing the member terminal 1, but is registered in the member terminal 1 in advance. Good. In this case, since an operation for inputting an address or the like is not required at all, the user can use the member terminal 1 without making the user aware of the common server device.

  As will be described later, when the facsimile communication or e-mail communication is started at the member terminal 1, the member having a contract relationship with the previously stored address information and the common server device 2 is preceded. The member terminal 1 automatically executes a process of connecting to the common server device 2 using the identification information indicating that it is a terminal.

  In this embodiment, the member terminal 1 is excellent in portability, and realizes its communication function and its related function by cooperating with the common server device 2.

  That is, the member terminal 1 does not have a large capacity memory. Instead, the common server device 2 includes a memory or a memory area for each member terminal 1. In addition, the member terminal 1 leaves the application for realizing various functions to the common server device 2 except for the application (microcomputer software) for the minimum necessary processing. That is, in the member terminal 1, when the user performs a key operation corresponding to a request for obtaining a target function, for example, the request is sent to the common server device 2, and the common server device 2 The application is executed. Then, the processing result of the application is sent to the member terminal 1.

  The above is the outline of the configuration of the embodiment of the present invention. A more specific configuration will be described below.

  FIG. 6 is a more specific example of the conceptual configuration of the communication network system of FIG. 5 described above. In this case, the member terminal 1 has a configuration of a multifunction device of a PHS telephone terminal and a PDA (Personal Digital Assistance) having a data communication function. In addition to the PHS telephone function, as will be described later, facsimile communication is performed. It has a function and an electronic mail communication function, and also has a function of receiving information provided from the service content stored in the common server device 2 or from the content providing device 11.

  In this example, the network 3 for the portable radio communication terminal to which the radio base station 6 is connected is the PHS / ISDN network 3n. Accordingly, the member terminal 1 can perform telephone communication with another member terminal 1 or a PHS terminal other than the member through the wireless base station 6-PHS / ISDN network 3n-wireless base station 6, and the wireless base station 6-PHS / ISDN. Telephone communication with a general subscriber telephone terminal is possible through the network 3n.

  In this example, the dedicated backbone network 5 is a network managed by an ISP (Internet Service Provider). That is, 5N is an ISP backbone, that is, a network such as a LAN. The ISP backbone 5N and the PHS / ISDN network 3n are PIAFS (PHS, which is an industry standard system for a PHS transmission rate of 32 kbit / s. It is connected through an access point 4P for Internet Access Forum Standard.

  Reference numeral 5N denotes an ISP router, through which the ISP backbone 5N, the ISP server device 7I corresponding to the network management server device 7, and the common server device 2 are connected.

  The ISP server device 7I authenticates when there is an access from the member terminal 1, as described above, on consignment from the common server device 2 side. That is, in the ISP server device 7I, member information (identification information) of the member terminal 1 that accesses the common server device 2 via the ISP server device 7I, for example, an e-mail address is registered in advance. 7I indicates whether or not the terminal that has accessed the terminal connected to the ISP backbone 5N is the member terminal 1 to be connected to the common server device 2 through the ISP backbone 5N. If the authentication is performed and the member terminal 1 is used, the access is made to be received by the common server device 2 through the router 5R. Then, the ISP server device 7I sends the access history (log) of the member terminal 1 to the common server device 2.

  In this example, the content providing apparatus 11 is connected to the common server apparatus 2 through the Internet 8, and information to be provided by the common server apparatus 2 is supplied to the common server apparatus 2 through the Internet 8 and stored. To be. As described above, content information can be provided not through the Internet 8 but through a dedicated line, or stored in an optical disk medium such as a CD-ROM or other storage medium and stored in the common server device 2. It can of course be provided as

In the flash memory 124, the member terminal 1 is a terminal that has a contract relationship with the common server device 2, and can receive a facsimile communication service, an e-mail service, and an information providing service from the common server device 2. In addition to indicating that the terminal can be used, identification information (member information) for identifying each member terminal is also stored.

  The member information is stored in the main server 21 of the common server device 2 and is also managed in the common server device 2. The ISP server device 7I also authenticates whether or not it is a member who has accessed with this member information.

  Further, the flash memory 124 is provided with an area for storing data to be particularly stored among the received data temporarily stored in the DRAM 123.

  The operation of the member terminal 1 having the above configuration will be described below including the operation of the related common server device.

  First, the PHS telephone mode will be described. When the telephone number of the other party is dialed using the numeric keypad 102 with the cover panel 101 closed, a call is made. When the member terminal 1 as the PHS telephone terminal receives a call with the cover panel 101 closed, the user is notified by the buzzer 127, and when the user answers, the telephone call is received. Can talk.

  When a call is received with the cover panel 101 opened, a call can be made at any time by pressing the call key K3, which is one of the key buttons 108. However, the call is made with the cover panel 101 closed.

  Then, during the PHS telephone call, the member terminal 1 transmits a transmission signal and receives a reception signal while the transmission / reception data processing unit 113 receives control from the system control unit 121.

  That is, an audio signal from the microphone 100MC is supplied to the transmission / reception data processing unit 113 via the amplifier 114 and converted into transmission data, and is transmitted to the radio base station 6 through the antenna 111 through the RF processing unit 112. Call voice data from the counterpart side from the radio base station 6 is received by the antenna 111, the received data is processed by the transmission / reception data processing unit 113, and the call voice signal of the other party is restored. The sound is supplied to 100SP and emitted.

  Next, the data communication mode will be described. In this communication mode, the member terminal 1 is configured to realize a facsimile function, an e-mail function, a WWW browser function, a memo function, and the like. A list menu of these functions is displayed on the screen of the main LCD 105M by operating a menu key of the key buttons 108. Then, the user selects and determines a desired function from the list menu displayed on the screen of the main LCD 105M by rotating and pressing the jog dial key 109, so that the member terminal 1 has the function. It will be in the state of executing mode.

  In the member terminal 1 of this embodiment, transmission and reception of facsimile data and transmission and reception of e-mail are all processed via the common server device 2.

  The data exchange between the member terminal 1 and the common server device 2 is performed by a communication method that is compatible with the network 3 and the network 5 regardless of the default communication method as the facsimile communication method. . That is, in the case of this embodiment, the facsimile data and the e-mail data are stored in the PHS network using SMTP (Simple Mail Transfer Protocol), which is a standard procedure used for transferring e-mail over the Internet. Transmission data and reception data are exchanged between the member terminal 1 and the common server device 2 by the utilized PIAFS method.

  In this case, in the member terminal 1, the transmission data is temporarily stored in the DRAM 123, read out by the system control unit 121 by execution of transmission, and transmitted / received data processing unit 113, RF processing unit in the above-described communication protocol and data format. 112 and wirelessly transmitted via the antenna 111 sequentially.

  Also, the reception data from the common server device 2 is received by the antenna 111 and temporarily stored in the DRAM 123 by the system control unit 121 through the RF processing unit 112 and the transmission / reception data processing unit 113. Then, under the control of the system control unit 121, it is sent as display data to the main LCD 105M through the LCD driver 125, and the display content by the received data is displayed.

  The memo function includes a “handwritten memo” that is input using the pen 107 and the touch panel 106, and a “type memo” that displays a keyboard on the screen of the main LCD 105M and creates a document using the display keyboard. There is. In both the handwritten memo and the type memo, the created image or document can be transmitted as facsimile data.

  That is, in either the handwritten memo or type memo mode, a menu bar including a “FAX transmission (facsimile transmission)” icon is displayed on the screen of the main LCD 105M, and this “FAX transmission” icon is displayed. For example, when a selection is made with a pen, an input mode screen such as a telephone number of a partner terminal to be transmitted and a facsimile title is displayed. Then, after inputting the phone number and title of the other party's terminal and selecting the “Send” icon displayed in this mode, the image or document created with the handwritten memo or type memo is sent as facsimile data .

  However, as described above, since the facsimile data is transmitted to the common server apparatus 2 as e-mail data in this case, the image data and document data are not bitmap data for facsimile communication, and the image data is, for example, GIF (Graphics Interchange). Format), and the document data is in a text data format.

  When the destination is other than the member, the common server device 2 converts the received data into bitmap data and performs facsimile transmission to a terminal other than the member. When the destination is the member terminal 1, the common server device 2 stores the received data in the mail box 22M or the FAX box 23M, and each member terminal 1 is addressed to the member terminal 1 through the incoming call notification server 24. Notify that there was an incoming call. This incoming notification is performed not only when receiving facsimile data but also when receiving e-mail data.

  When the on-line connection key K2 of the key buttons 108 is pressed when the facsimile function is selected, the member terminal 1 automatically performs a process for connecting to the common server device 2. That is, the member terminal 1 sends out a request to connect to the common server device 2 using the address data in the flash memory 124. Then, the ISP server 7I, which is a network management server, authenticates whether or not the accessed terminal is a member terminal, and if it is a member terminal, processing to connect to the common server device 2 is performed.

  The common server device 2 recognizes the connected member terminal, creates a list of received facsimile data addressed to the member terminal, and sends it to the member terminal 1. Accordingly, in this example, the online connection key K2 also serves as a request key for the received data list.

  The member terminal 1 receives the data of the list from the common server device 2, temporarily stores it in the DRAM 123, and displays the list on the screen of the main LCD 105M. The user can select desired facsimile reception data from this list by using the jog dial key 109 or the pen 107. When the desired facsimile reception data is selected and the “capture” icon is selected, the member terminal 1 transmits a request for acquisition of the reception data to the common server device 2.

  Upon receiving this request, the common server device 2 extracts the requested facsimile reception data and sends it to the member terminal 1 by SMTP of electronic mail. The member terminal 1 temporarily stores the received data in the DRAM 123, converts it into display data, and displays it on the screen of the main LCD 105M. Therefore, the user can select the necessary facsimile data and view it on the screen of the main LCD 105M.

  When this facsimile data is received and displayed, the member terminal 1 can request the common server device 2 to enlarge or rotate the received data so that the received data can be easily viewed. That is, when the user selects the “enlarge” or “rotate” icon displayed on the screen of the main LCD 105M, the member terminal 1 is requested to process the received data for enlargement or rotation. A reception data request is transmitted to the common server device 2.

  The common server device 2 receives this request, applies the processing corresponding to the request to the facsimile reception data currently provided to the member terminal 1, and makes the request to the member terminal 1 that has made the request. Send to address. The member terminal 1 receives this, temporarily stores it in the DRAM 123, and displays the received data processed as requested on the screen of the main LCD 105M.

  Also, when the e-mail function is selected, when the online connection key K2 of the key buttons 108 is pressed, the member terminal 1 is connected to the common server in the same manner as when the facsimile function is selected. A process for connecting to the apparatus 2 is automatically performed. Then, the common server device 2 creates a list of received e-mail data and sends it to the member terminal 1.

  The member terminal 1 receives the list data and displays the list on the screen of the main LCD 105M. Then, the user can use the jog dial key 109 or the pen 107 to select desired received e-mail data from the list. When the received data of the desired e-mail is selected and the “capture” icon is selected, the member terminal 1 transmits a request for acquisition of the received data to the common server device 2.

  In response to this, the common server device 2 extracts the received data of the requested electronic mail and sends it to the member terminal 1 by SMTP. The member terminal 1 temporarily stores the received data in the DRAM 123, converts it into display data, and displays it on the screen of the main LCD 105M.

  In the case of the WWW browser function, transmission data and reception data are exchanged between the member terminal 1 and the common server device 2 by the PIAFS method using the PHS network using HTTP (Hyper Text Transfer Protocol).

  Also in the e-mail function, when e-mail data is displayed, a request for enlargement, rotation, etc., is sent from the member terminal 1 to the common server device 2 to make the received data easier to see. Similarly to the case of the facsimile function, the common server device 2 performs processing such as enlargement and rotation, and displays the received data on the screen of the main LCD 105M of the member terminal 1 with the requested processing being performed. be able to.

  As described above, in this embodiment, the member terminal 1 does not perform processing such as enlargement and rotation on the received data, and the common server device 2 executes the processing. For this reason, the system control unit 121 of the member terminal 1 does not need to have an application for processing the received data, reduces the burden on the CPU, and allows the terminal 1 to be manufactured at low cost. Become.

  In this embodiment, the member terminal 1 does not need to have an application for the generation process or the processing process regarding the related information related to the received data. That is, as described above, when the facsimile function and the e-mail function are selected from the menu and the online connection key K2 is pressed, the facsimile reception data list and the e-mail reception list addressed to its member terminal are stored in the common server device 2. Generated and sent. The member terminal 1 can select and view the received data to be viewed from this list.

  Further, in this embodiment, the processing of related information such as this list is configured so that the common server device 2 performs the request of the member terminal 1. For example, the list is rearranged in the order of the Japanese syllabary according to the name and title of the sender, not in the order of incoming calls, or the parties with the same telephone number or e-mail address are rearranged together (sorting). You can request a list that extracts only certain items of mail.

  For example, when the reception list is displayed on the screen of the main LCD 105M in the facsimile function or the e-mail function, for example, the user makes the sort request by an operation using an icon on the screen of the main LCD 105M. Then, the member terminal 1 transmits the request signal to the common server device 2. Upon receiving the request signal, the common server device 2 confirms the membership, sorts the requested reception list according to the request, and requests the received list after the sorting process. Send to terminal 1. The member terminal 1 receives this, temporarily stores it in the DRAM 123, displays it on the screen of the main LCD 105M, and provides the user with a sorted reception list.

  Thus, in this embodiment, since the common server device 2 also generates information related to received data and processes it, the member terminal 1 has an application for generating and processing related information. In this respect, the burden on the CPU of the member terminal 1 is reduced.

[Mode switching processing]
Next, a mode switching process for switching between the telephone mode and the data communication mode in accordance with the opening / closing of the cover panel 101 will be described with reference to the flowchart of FIG .
