Description

  The present invention relates to a communication terminal device such as a personal computer, a portable information terminal, and a mobile phone, and more particularly to a communication terminal device having a function of receiving electronic mail such as Internet mail or mail unique to a communication carrier.

  In general, the conventional e-mail delivery service method receives an e-mail transmitted from a terminal device on the transmission side by a mail server and temporarily accumulates it, and then the header information, the body text, and the The attached data is downloaded as a set to the destination terminal device.

  However, when such an e-mail delivery service is used, the full text of the e-mail is unconditionally downloaded to the receiving terminal device regardless of the e-mail text or the amount of attached file data. For this reason, depending on the memory capacity of the terminal device on the receiving side, the memory may soon fill up. This is a big problem particularly in a portable terminal such as a cellular phone having a relatively small memory capacity. Even if the contents of the e-mail body or the attached file are unnecessary advertisements or malicious data, they are received unconditionally. In such a case, the user on the receiving side must bear a communication fee for the download of the unnecessary electronic mail, which is very undesirable because it suffers a great disadvantage.

  On the other hand, as another e-mail delivery service system, for example, a system called IMAP4 (Internet Message Access Protocol-Version 4), the mail server configures the e-mail according to the download format requested by the terminal device on the receiving side. There is a method in which header information, which is an element, a text, and an attached file are divided and downloaded (see, for example, Patent Document 1).

If such a method is adopted, the receiving side terminal device selectively receives the constituent elements of the e-mail so as to receive only the header information or only the header information and the text in consideration of the memory capacity or the like. It becomes possible to do.
JP-A-9-130423

  However, when the method described in Patent Document 1 is used, the user on the receiving side must manually download all e-mails addressed to him and specify the contents of the download. For this reason, the operation of receiving an e-mail becomes extremely complicated.

  The present invention has been made paying attention to the above circumstances, and its purpose is to perform a special operation for an e-mail from a necessary sender while avoiding the occurrence of insufficient memory capacity and receiving unnecessary mail. It is an object of the present invention to provide a communication terminal device having an e-mail receiving function that ensures easy operability without fail and automatically and reliably.

  In order to achieve the above object, the present invention connects to a mail server having a function of dividing an electronic mail transmitted from a transmission source into a plurality of components and selectively downloading them to a destination communication terminal device. In the communication terminal device to be used, a transmission source storage means for storing first transmission source identification information for identifying a desired mail transmission source in advance, and an e-mail addressed to itself from the mail server in a standby state When a specific component including the transmission source identification information has arrived among a plurality of components constituting the second transmission element, the second transmission source identification information included in the specific configuration element is stored in the transmission source storage unit A collation means for collating with the first transmission source information, and when the second transmission source identification information matches the first transmission source identification information as a result of the collation by the collation means, the mail Sending a download request to the server to obtain other components constituting the self-addressed e-mail, and configuring the self-addressed e-mail acquired by the mail automatic reception control means And display means for displaying other components.

Further, the present invention provides the communication used by connecting to a mail server having a function of dividing an electronic mail transmitted from a transmission source into a plurality of components and selectively downloading them to a destination communication terminal device In the terminal device,
Transmission source storage means for preliminarily storing first transmission source identification information for identifying an undesired mail transmission source, and transmission among a plurality of components constituting the self-addressed e-mail from the mail server in a standby state When a specific component including the original identification information arrives, the second transmission source identification information included in the specific component is collated with the first transmission source information stored in the transmission source storage unit. When the second transmission source identification information does not match the first transmission source identification information as a result of the verification by the verification unit and the verification unit, a download request is sent to the mail server, As a result of collation by the automatic mail reception control means for acquiring other components constituting the electronic mail and the collation means, the second transmission source identification information matches the first transmission source identification information. If the user performs an operation for requesting download in response to the notification of the message by the notification means, the download request is sent to the mail server and the self It is also characterized by comprising a mail manual reception control means for receiving an e-mail addressed thereto.

  Therefore, according to these inventions, the e-mail from the sender registered in advance can be automatically received without any operation by the receiving user, including the attached file, by the receiving user. The operational complexity is eliminated. On the other hand, the full text of e-mails from general senders will not be downloaded unconditionally, which makes it possible to use this limited memory capacity more effectively when the memory capacity is small. Further, it is possible to avoid a problem that unnecessary advertisements and malicious data are received unconditionally.

  That is, according to the present invention, it is possible to automatically and reliably receive an e-mail from a necessary sender without performing a special operation while avoiding the occurrence of insufficient memory capacity and receiving an unnecessary mail. Thus, it is possible to provide a communication terminal device having an e-mail receiving function that ensures good operability.

  FIG. 1 is a schematic configuration diagram of a mobile communication network system to which a mobile terminal which is an embodiment of a communication terminal apparatus according to the present invention is connected.

  A plurality of base stations BS1 to BSn are distributed in a service area covered by the system, and these base stations BS1 to BSn each form a radio zone called a cell. The base stations BS1 to BSn are each connected to the mobile communication network NW via a wired line. The mobile communication network NW is connected to a computer network such as a wired communication network or the Internet (not shown).

  The mobile terminals MS1, MS2,... Are connected to the base stations BS1 to BSn forming the radio zone in the radio zone via a radio channel, and further connected to the mobile communication network NW from the base stations BS1 to BSn. . The mobile communication network NW is exchange-controlled so that it can be connected to other portable terminals in the system or other wired terminals connected to the wired communication network. It becomes.

  In addition to the exchange control function, the mobile communication network NW includes an Internet mail distribution service function for performing an electronic mail distribution service. This Internet mail distribution service function is to transfer and distribute an electronic mail (E-mail) that is a source or destination of the mobile terminals MS1, MS2,... Via the Internet according to the TCP / IP protocol. For this purpose, a mail server SV is provided.

  The mail server SV receives the electronic mail sent from the terminal on the transmission side, temporarily stores it, and distributes the electronic mail to the destination mobile terminal according to the protocol defined by IMAP4. The IMAP 4 divides the header information, body, and attached file, which are constituent elements of the e-mail, according to the download format requested by the destination mobile terminal, and downloads these constituent elements in any combination.

  As a download combination pattern, for example, header information, body text, and attached file are downloaded in response to separate download requests after mail arrival notification, and header information is first downloaded in response to a download request after mail arrival notification. After downloading the body and attached file together in response to another download request, download the header information and body in response to the download request after notification of incoming mail, and then download the attached file in response to another download request There is something to do. It is also possible to divide a plurality of elements constituting the header information and selectively download them in response to a download request.

By the way, the portable terminals MS1, MS2,... Are configured as follows. FIG. 2 is a block diagram showing the functional configuration.
Radio frequency signals transmitted from the base stations BS1 to BSn are received by the antenna 1 and then input to the receiving circuit (RX) 3 via the antenna duplexer 2 (DUP). In the reception circuit 3, the radio frequency signal is mixed with the reception local oscillation signal output from the frequency synthesizer (SYN) 4 and converted into an intermediate frequency signal. The frequency of the reception local oscillation signal generated from the frequency synthesizer 4 is instructed by a control signal SYC from the control unit 12.

  The received intermediate frequency signal is despread in the CDMA signal processing unit 6 using a spreading code (PN code) assigned to the receiving channel, and then subjected to, for example, orthogonal demodulation corresponding to the QPSK modulation method. Thus, the data is converted into demodulated data in a predetermined format corresponding to the data rate. The converted demodulated data is input to the compression / decompression processor 7.

  The compression / decompression processing unit 7 performs a decompression process on the demodulated data output from the CDMA signal processing unit 6 according to the reception data rate notified from the control unit 12, and then performs a decoding process using Viterbi decoding or the like In addition, error correction decoding processing is performed to reproduce baseband received voice data or received packet data. The received voice data is output to the PCM code processing unit 8, and the received packet data is output to the control unit 12.

  The PCM code processing unit 8 performs PCM decoding on the received voice digital data output from the compression / decompression processing unit 7 and outputs an analog received signal. The analog reception signal is amplified by the reception amplifier 9 and then output from the speaker 10 as a loud voice.

  The control unit 12 depackets the received packet data output from the compression / decompression processing unit 7 and stores it in the storage unit 13, and also reads out the received packet data from the storage unit 13 and displays it on the display unit 15 in accordance with a user display operation by the input unit 14. To do. When a personal computer such as a personal digital assistant (PDA) or a notebook personal computer is connected to the mobile terminals MS1, MS2,..., An external interface (not shown) is used for the received packet data. In some cases, the data is output to this personal computer.

  On the other hand, the speaker's input voice signal input to the microphone 11 during voice communication is amplified to an appropriate level by the transmission amplifier 18 and then subjected to PCM encoding processing by the PCM code processing unit 8 to transmit the transmission voice. The data is input to the compression / decompression processing unit 7 as data. Further, packet data such as e-mail created by the control unit 12 is input from the control unit 12 to the compression / decompression processing unit 7.

  At the time of voice communication, the compression / decompression processing unit 7 detects the energy amount of the input voice from the transmission voice data output from the PCM code processing unit 8, and determines the data rate based on the detection result. Then, the transmission voice data is compressed into a signal having a format corresponding to the data rate, further subjected to error correction coding processing, and then output to the CDMA signal processing unit 6. On the other hand, at the time of packet data transmission, the transmission packet data output from the control unit 12 is subjected to error correction coding processing and output to the CDMA signal processing unit 6.

  The CDMA signal processing unit 6 performs, for example, QPSK modulation on the carrier signal with the transmission data compressed in the compression / decompression processing unit 7, and uses the PN code assigned to each transmission channel for the modulated carrier signal. Apply spread spectrum processing. Then, the spread coded transmission signal is output to the transmission circuit (TX) 5.

  The transmission circuit 5 combines the spread-encoded transmission signal with a transmission local oscillation signal generated from the frequency synthesizer 4 and converts the frequency into a radio frequency signal. The transmission circuit 5 amplifies only the effective portion of the radio frequency signal based on the transmission data rate notified by the control unit 12 and outputs the amplified signal as a transmission radio frequency signal. The transmission radio frequency signal output from the transmission circuit 5 is supplied to the antenna 1 via the antenna duplexer 2 and transmitted from the antenna 1 to the connected base station.

  The input unit 14 is provided with a key group such as a dial key, a call key, a power key, an end key, a volume control key, and a mode designation key. The display unit 15 is provided with an LCD display and an LED lamp. The LCD display displays the telephone number of the communication partner's terminal and the operating state of the terminal itself, as well as sent / received mails. The LED lamp is used to display the discharge state of the battery 16. Reference numeral 17 denotes a power supply circuit, which generates a predetermined operating power supply voltage Vcc based on the output of the battery 16 and supplies it to each circuit unit.

  Incidentally, the storage unit 13 is provided with a received mail storage unit 13a and a transmission source identification information storage unit 13b in addition to an address book and a data storage unit for voice recording / playback. Among these, the received mail storage unit 13a is used for storing received electronic mail addressed to itself. The transmission source identification information storage unit 13b is used to store transmission identification information of a specific sender who desires automatic reception of mail. As the sender identification information, for example, an e-mail address or a sender telephone number or both are used.

  The control unit 12 includes a microprocessor as a main control unit. The control function includes a communication link control function for establishing a communication link with the base station in response to outgoing / incoming calls, and a control function for recording / reproducing the voice of the other party using the storage unit 13 during voice communication. In addition to a normal control function such as a mail manual reception control function in which the receiving user manually downloads an e-mail, a new function related to the present invention is a sender verification function 12a, an automatic mail reception control function 12b, And an inquiry display control function 12c.

  The sender verification function 12a stores in advance the sender identification information included in the mail arrival notification in the sender identification information storage unit 13b of the storage unit 13 when a mail arrival notification arrives from the mail server SV. It is checked against the source identification information of a specific sender, and the presence or absence of matching information is determined. Further, when the sender identification information is not included in the mail arrival notification, a header information download request is transmitted to the mail server SV, and the request is transmitted from the header information transmitted from the mail server SV. The original identification information is extracted and the above verification is performed.

  The automatic mail reception control function 12b, when the sender identification information matching the received sender identification information is stored as a result of the verification by the sender verification function 12a, A request for downloading undelivered components, that is, a body and an attached file, and a body and an attached file downloaded from the mail server SV in response to the download request, together with the header information received earlier, the received mail storage unit of the storage unit 13 Store in 13a.

  The inquiry display control function 12c downloads the e-mail text and attached file when the transmission source identification information that matches the received transmission source identification information is not found in the storage unit 13b as a result of the verification by the transmission source verification unit 12a. Is displayed on the display unit 15 for inquiring of the user whether or not to perform the operation immediately.

  Next, the automatic mail reception control operation by the portable terminals MS1, MS2,... Configured as described above will be described. FIG. 3 is a flowchart showing the control procedure and contents, and FIG. 4 is a sequence diagram showing a signal transmission procedure among the transmission side terminal, the mail server and the reception side terminal.

  Prior to the reception of mail, each user registers the mail address of the sender who desires automatic reception of mail in the transmission source identification information storage unit 13b of the storage unit 13 in each mobile terminal MS1, MS2,. This registration is performed by key-inputting the mail address of the sender who wishes to receive mail automatically at the input unit 14 in a state where the control unit 12 is set to the sender registration mode by the key operation of the input unit 14. FIG. 5 shows an example of the registration result.

  Now, it is assumed that an electronic mail is transmitted from the mobile terminal MS1 to the mobile terminal MS2. The user of the portable terminal MS1 inputs his / her source address, destination mail address and message as header information by operating the input unit 14 and creates an e-mail body, and further, for example, a still image of his / her face Attach the data or audio data defined as your own ringtone as an attached file. Then, this electronic mail is transmitted.

  Then, the electronic mail is transferred to the mail server SV via the base station BS1 and the mobile communication network NW as shown in FIG. 1, and is received and temporarily stored by the mail server SV. When an e-mail arrives, the mail server SV first transmits a mail arrival notification to the destination mobile terminal MS2 based on the destination e-mail address described in the header information of the e-mail as shown in FIG. .

  On the other hand, in the standby state, the destination mobile terminal MS2 monitors incoming calls, and monitors the arrival of an incoming mail notification in step 3a as shown in FIG. In this state, when a mail arrival notification arrives, the sender identification information, that is, the mail address of the sender in this case is extracted from this mail arrival notification.

  However, the sender identification information may not be included in the incoming mail notification depending on the system configuration and the type of sender identification information used. Therefore, the control unit 12 of the portable terminal MS2 determines whether or not the sender identification information is included in the mail arrival notification in step 3b. If not, the header information is sent to the mail server SV in step 3c. Request for download, that is, a download request. When the header information is downloaded from the mail server SV in response to the download request, the header information is received in step 3d, and the sender identification information is extracted from the header information.

  Then, when the sender identification information is extracted, the control unit 12 of the portable terminal MS2 next, in step 3e, from the incoming mail notification or the contents of the header information, the photo in which the electronic mail has inserted image data or audio data into the attached file. It is determined whether the mail is a specific mail called mail or the like. If it is not a specific mail, the process shifts to a normal mail manual reception control operation in which an electronic mail is downloaded according to a manual operation by the user.

  Now, suppose that the target e-mail is a photo mail. Then, the control unit 12 of the mobile terminal MS2 determines that the electronic mail is a target for automatic download, and moves to Step 3f where the transmission source mail address previously extracted from the mail arrival notification or header information is stored in the storage unit 13. The sender mail address stored in the sender identification information storage unit 13b is collated.

  Then, as a result of this collation, if a sender email address that matches the sender email address extracted from the email arrival notification or header information is stored in the sender identification information storage unit 13b, the process proceeds to step 3j. Then, a request for downloading the body of the electronic mail addressed to itself and the attached file is transmitted to the server SV. In response to the download request, when the body and attached file of the e-mail addressed to itself are downloaded from the mail server SV, the body and the attached file are received and stored together with the header information received earlier. Stored in the received mail storage unit 13a. At the same time, the stored text and attached file are read out and displayed on the display unit 15 in step 3k.

  At this time, for example, the display order is set so that the attached file is displayed first, and the text is displayed after a certain period of time or according to the user's operation. In this case, in the case of a photo mail, the sending user's face image data inserted in the attached file is displayed first, so that the receiving user can immediately recognize the sending user from this face image. Become.

  When audio data uniquely determined by the transmitting user is inserted in the attached file, the audio data is reproduced and output as a ringing melody from a speaker or a sounder instead. For this reason, the receiving user can immediately recognize the transmitting user by this incoming melody.

  On the other hand, it is assumed that, as a result of the collation in step 3g, a sender email address that matches the sender email address extracted from the email arrival notification or header information is not stored in the sender identification information storage unit 13b. In this case, the control unit 12 of the mobile terminal MS2 generates a message for inquiring the receiving user whether or not to immediately download the body of the e-mail and the attached file in step 3h, and causes the display unit 15 to display this inquiry message. . When displaying the inquiry message, a sound indicating that the inquiry message is displayed may be generated at the same time.

  While the inquiry message is displayed, the control unit 12 monitors the operation by the receiving user in step 3i. Then, when the receiving user inputs that he / she wants to download the email immediately within a certain time after the display of the inquiry message, the control unit 12 proceeds to step 3j, where the text is as described above. In addition, the download control of the attached file is executed, and the display control of the text of the electronic mail and the attached file downloaded in step 3k is executed.

  If the receiving user inputs that he / she does not wish to immediately download the e-mail or does not perform any operation within a certain time after the start of the display of the inquiry message, the control unit 12 performs normal mail manual operation. Transition to reception control operation.

  As described above, in this embodiment, the mail address of the sender who wishes to receive mail automatically is registered in advance in the sender identification information storage unit 13b of the storage unit 13, and a mail arrival notification is received from the mail server SV. In this case, the mail address of the sender included in the incoming notification is collated with the sender mail address stored in the sender identification information storage unit 13b. If the matching sender mail address is stored in the storage unit 13b, a download request is transmitted to the mail server SV to automatically download the text and attached file and display them on the display unit 15. I have to.

  Therefore, according to this embodiment, the e-mail from the sender registered in advance can automatically receive the body text and the attached file without any operation by the receiving user. The above complication is eliminated. On the other hand, the full text of e-mails from general senders will not be downloaded unconditionally, which makes it possible to use this limited memory capacity more effectively when the memory capacity is small. Further, it is possible to avoid a problem that unnecessary advertisements and malicious data are received unconditionally.

  Also, when the sender identification information is not included in the incoming mail notification received from the mail server SV, a request for downloading the header information of the email is sent to the mail server SV, and the request is downloaded from the mail server SV. The sender identification information included in the header information is collated with the sender mail address stored in the sender identification information storage unit 13b.

  Therefore, even if the sender identification information is not included in the incoming mail notification depending on the system configuration and the sender identification information type, the sender can be verified. Automatic download can be performed.

  Further, when a matching transmission mail address is not found as a result of collation of the transmission source mail address, the user is inquired whether to immediately download the body of the electronic mail and the attached file. When the receiving user inputs a request for immediate download of the e-mail in response to the inquiry, download control of the text and attached file is executed, and display control of the downloaded text and attached file is executed. Yes.

  Therefore, the receiving user can automatically download and display an e-mail from a sender who has not registered a sender e-mail address as needed without ignoring it.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the transmission unit identification information storage unit 13b is provided in the storage unit 13, and the transmission source email address of the sender who wishes to receive mail automatically is registered therein. In the case where it is already provided in the storage unit 13, a sender who wishes to receive mail automatically may be registered using these address data.

  FIG. 6 shows an example of the registration method. A column for writing an automatic reception flag F is provided in the address book, and a sender who wants automatic reception of mail among a plurality of senders registered in the address book. The automatic reception flag F is stored in the column.

  In this way, since the existing transmission / reception history and address book can be used, the transmission source identification information storage unit 13b can be dispensed with, and the storage unit 13 can be used effectively accordingly.

  In the above embodiment, the e-mail to be automatically downloaded has been described by taking a specific e-mail called a photo e-mail in which image data or audio data is inserted in the attached file as an example. It may be a normal e-mail with data inserted therein.

  Furthermore, in the above-described embodiment, the Internet mail has been described as an e-mail, but the present invention can be similarly applied to other types of e-mail. For example, some systems have a message notification service function unique to a carrier. This message notification service function is called a short message service or the like. By using a message server connected to the network of the telecommunications carrier, the length of a message that can be transmitted between mobile terminals that subscribe to its own network. Saga transmits text messages shorter than Internet mail according to the carrier's own protocol. In this case, the present invention can be implemented by providing the message server with a function for dividing and downloading each component of the message following the mail arrival notification such as IMAP4.

  In the embodiment, the mail address of the sender who wishes to receive mail automatically is registered in advance. However, if the sender's email address that does not wish to receive emails is registered in advance, and the sender identification information is not found in the registered email address when the email is received, The attached file may be automatically downloaded.

  Furthermore, in the above-described embodiment, the mobile terminal MS1, MS2,... Such as a mobile phone has been described as an example of the communication terminal device. However, if it is a communication terminal having an electronic mail receiving function, a personal digital assistant (PDA) ), Notebook personal computers, and the like.

  In addition, the type and configuration of the communication terminal device, the type of electronic mail, the procedure and contents of automatic mail reception control, and the like can be variously modified without departing from the scope of the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
