The mail received by the packet communication control unit 29 can also be stored in the SIM card 53.

  The operation of the mobile phone 1 configured as described above will be described below. First, the operation during standby of the mobile phone 1 in the present embodiment will be described. The standby is processing that is performed at a time other than during a call, connection to a network, or packet communication, and includes location registration processing and paging processing.

  FIG. 5 is a flowchart showing an example of the procedure of the location registration process of the mobile phone 1 of the present embodiment. FIG. 7 is a timing chart for explaining the reception timing of the paging channel signal in the mobile phone 1 of the present embodiment. Hereinafter, description will be made with reference to FIGS. 1, 5, and 7.

  First, when the power of the mobile phone 1 is turned on, or when the mobile phone 1 moves to another area and the nearest base station changes, the location registration process starts. The mobile phone 1 can recognize the nearest base station from the base station group constituting the mobile communication system on the basis of the radio wave intensity and the like. The mobile phone 1 is informed of where the mobile phone 1 is.

  First, the location registration unit 23 of the main control unit 21 searches for a base station capable of wireless communication with the mobile phone 1 via the wireless unit 5 (step S11). If there is a corresponding base station (YES in step S13), the location registration unit 23 establishes synchronization with the base station via the wireless unit 5 (step S15).

  After synchronization is established, the location registration unit 23 recognizes the SIM card 53 installed in each card slot 51 through the card interface unit 43 and reads the terminal information 80 recorded on each SIM card 53. The location registration unit 23 reads the telephone number A of the SIM card 53a installed in the card slot 51a and the telephone number B of the SIM card 53b installed in the card slot 51b, and sends the telephone number A and the telephone number to the base station. B location registration is performed (step S17). In other words, every time a location registration operation such as changing the location registration area is performed when the power is turned on, the location registration processing is sequentially performed with the phone number A and the phone number B. In this case, even when there is an incoming mail, the mobile communication system side can recognize where the mobile phone 1 with the SIM card, which is registered with the telephone number, is located.

  In step S17, the terminal information 80 of each telephone number is read from the SIM card 53 after the synchronization with the base station is established. However, the present invention is not limited to this. The terminal information 80 of each telephone number is read from the SIM card 53 at the time of power-on or at an arbitrary time, stored in advance in the telephone number information 90 of the memory unit 41, and thereafter read from the telephone number information 90 as needed. it can.

  In step S17, the base station allocates a paging channel for telephone number A and a paging channel for telephone number B, and sends system information including these information to the terminal. Note that paging channel allocation is performed in units of groups including the telephone numbers of other terminals that have requested location registration. In this embodiment, since one terminal has two telephone numbers, two paging channels of a group including the telephone number A and two paging channels including a telephone number B are allocated as shown in FIG. Become. Then, in the cellular phone 1, the position registration unit 23 of the main control unit 21 receives this system information transmitted from the base station via the radio unit 5 (step S19).

  Subsequently, based on the system information received in step S19, the paging unit 25 sets the timing of the paging channel for the telephone number A and the paging channel for the telephone number B (step S21). The set timing is stored for each telephone number in the telephone number information 90 of FIG. A paging process described later is executed at the set timing (step S23). In the present embodiment, it is assumed that the timing of each telephone number is as shown in FIG. In FIG. 7, the telephone number A and the telephone number B are at different timings, but may be the same timing. In that case, the cellular phone 1 determines the priority of processing after receiving the paging channel signal, and processes each telephone number according to the priority.

  In this way, the location registration is performed on the network side for both the telephone number A and the telephone number B by the two SIM cards 53a and the SIM card 53b. As shown below, the two telephone numbers are set respectively during standby. By performing the paging process at the same timing, both telephone numbers A and B can be simultaneously waited.

  FIG. 6 is a flowchart showing an example of the procedure of the paging process of the mobile phone 1 of the present embodiment. Hereinafter, description will be made with reference to FIGS. 1, 4, 6 and 7.

  First, the paging unit 25 of the main control unit 21 monitors reception of the paging channel at a reception timing corresponding to the telephone numbers A and B in a predetermined cycle (steps S31 and S33). The reception timing is the timing set in step S19 in FIG. 5, and follows the reception timing stored for each telephone number in the telephone number information 90 in FIG. When the reception timing of the paging channel corresponding to the telephone number A is reached (YES in step S31), the receiving circuit 13 of the wireless unit 5 is turned on to receive the paging channel signal (step S35). The paging channel signal includes a plurality of telephone numbers of a group including the telephone number A. Therefore, the paging unit 25 determines whether or not the telephone number A is included in the paging channel signal. If the telephone number A is included (YES in step S37), the paging unit 25 sends a mail to the incoming unit 27 of the main control unit 21. Notify that there was an incoming call.

  The incoming call unit 27 receives the incoming call notification information 100 from the server via the wireless unit 5 (step S41). The incoming call unit 27 recognizes the telephone number (mail address) at which an incoming mail has been received based on the received incoming call notification information 100. On the other hand, if the paging channel signal does not include the telephone number A (NO in step S37), the main control unit 21 turns off the receiving circuit 13 (step S39) and returns to step S31 until the next reception timing. Wait (NO in step S31 and NO in step S33).

  When the reception timing of the paging channel corresponding to the telephone number B is reached (YES in step S33), the main control unit 21 turns on the receiving circuit 13 and receives the paging channel signal at that time (step S35). . The paging channel signal at this time includes a plurality of telephone numbers of a group including the telephone number B. Accordingly, the paging unit 25 determines whether or not the telephone number B is included in the paging channel signal. If the telephone number B is included (YES in step S37), the mail is sent to the incoming unit 27 of the main control unit 21. Notify that there was an incoming call. The incoming call unit 27 receives the incoming call notification information 100 from the server via the wireless unit 5 (step S41). The incoming call unit 27 recognizes the telephone number (mail address) at which an incoming mail has been received based on the received incoming call notification information 100.

  On the other hand, if the paging channel signal does not include the telephone number B (NO in step S37), the main control unit 21 turns off the receiving circuit 13 (step S39) and returns to step S31 until the next reception timing. Wait (NO in step S31 and NO in step S33).

  In this way, it is possible to check whether there is a call from the base station at a timing corresponding to each of the telephone number A and the telephone number B, and to perform incoming processing of the telephone number that has been called. In this case, as shown in FIG. 7, while the telephone number A and the telephone number B are not checked, the mobile phone 1 enters a sleep state.

  In step S41, when the incoming mail notification is recognized at either the telephone number A or the telephone number B, the incoming call unit 27 uses the notification function such as the speaker 67 to confirm that the user has received an incoming mail. Notification is made (step S43). The incoming call unit 27 can also notify an incoming call with a predetermined vibration pattern by a vibration unit (not shown). Further, the receiving unit 27 can display a message to the effect that the incoming telephone number (mail address) is A or B on the LCD 61 to notify the user. Alternatively, it is also possible to notify and notify whether a mail has arrived and to which telephone number (mail address) by a predetermined lighting color or blinking pattern of an LED display (not shown). The incoming call notification process in step S43 is performed according to the operation setting information for incoming mail stored in the telephone number information 90 of FIG. In this way, different operation settings for incoming calls can be made for each telephone number.

  After that, when the user gives an instruction to receive an incoming mail, the key input unit 69 accepts the instruction (step S45), and the main control unit 21 sends an email acquisition request signal to the base station via the wireless unit 5. Send. This mail acquisition request signal includes information included in the above-described incoming notification information 100. The packet communication control unit 29 of the main control unit 21 acquires the mail transmitted from the base station via the reception circuit 13 of the wireless unit 5 (step S47). The packet data is received by the receiving circuit 13 via the antenna 11, amplified in signal level, converted to an arbitrary frequency, and digital demodulated, and then input to the baseband unit 7.

  The acquired mail is stored in the memory unit 41 in association with the telephone number. The received mail can be stored in the memory unit 41 by dividing the folder for each telephone number (mail address), or can be stored in one folder at a time. It is also possible to store each telephone number (mail address) in the SIM card. When the acquisition of the mail is completed, the packet communication control unit 29 sends a signal notifying that the acquisition is completed to the base station via the wireless unit 5 (step S49). The mail server deletes the mail that has received the notification of completion.

  The mail stored in the memory unit 41 can be sent to the LCD control unit 33 via the main control unit 21 and displayed as character information on the LCD 61 by a user operation, if necessary.

  As described above, according to the mobile phone 1 of the present embodiment, by performing paging processing for two telephone numbers at the set timings, it is possible to wait for two telephone numbers at the same time. In this embodiment, one mobile phone 1 has two telephone numbers (mail addresses). Even if mails are received simultaneously for both mail addresses, the mail server temporarily Since the mails can be collectively received by the mail acquisition request from the mobile phone 1 after the mails are accumulated, there is no need to particularly consider the contention and the priority order at the time of simultaneous reception. However, if there is an incoming voice call to the other phone number during packet communication with one phone number, the network side will not accept the incoming call if the incoming call processing is not performed. The numbered mobile phone 1 appears to be powered off. If packet communication and voice call are received simultaneously, there is no contention on the mobile phone 1 side, so both may be set to communicate simultaneously.

  Next, the operation at the time of mail transmission of the mobile phone 1 in the present embodiment will be described. In the mail transmission process, the user inputs a destination mail address by key entry or the like and performs a mail transmission procedure. At this time, the telephone number A and the telephone number B registered in the two SIM cards 53a and the SIM card 53b, that is, which of the different mail addresses can be selected, can be selected, so that two different contracting parties can be selected. That is, it is possible to distinguish the communication charge request destination. Specifically, for example, it corresponds to changing the billing destination by e-mail for work and private use.

  In addition to the above configuration, the mobile communication terminal (mobile phone 1) of the present embodiment has a transmission mail reception unit (key input unit 69, main control unit 21) that receives an instruction to create a transmission mail including a destination and a mail text. A transmission source reception unit (key input unit 69, main control unit 21) that receives a transmission source telephone number of a transmission mail selected from a plurality of telephone numbers, and a transmission using the telephone number received by the transmission source reception unit And a transmission unit (packet communication control unit 29, wireless unit 5) for transmitting mail.

The processing procedure when sending mail is as follows.
(1) Select SIM card (2) Input mail contents (destination, title, text)
(3) Press the send button (4) Send processing using the selected SIM card

  For procedure (1), the main control unit 21 instructs the LCD control unit 33 to display on the LCD 61 a SIM card selection screen that allows the user to select one of the two SIM cards 53. The user selects one of the SIM cards 53 by key operation, and the key input unit 69 accepts it. In this case, the SIM card type is associated with the telephone number or address registered therein, such as “SIM card 53a = phone number A = address A” and “SIM card 53b = phone number B = address B”. Displayed. The user arbitrarily selects either one of the displayed telephone numbers (mail addresses) and performs from the creation of the mail to the outgoing operation. It is also possible to set in advance so that any one of the SIM cards 53 is preferentially selected.

  With regard to the procedure (2), the e-mail address of the transmission destination may be directly input, or can be selected and designated from a pre-registered telephone book (address book). It is also possible to record a different phone book (address book) for each SIM card 53 in advance and acquire the phone book from the SIM card 53 selected in the procedure (1). Each telephone directory can also be shared or have a function of copying its contents.

  As for the procedure (3) and the procedure (4), the same transmission processing as usual is performed with the telephone number (mail address) of the selected SIM card 53. The communication fee is charged for the telephone number of the selected SIM card 53.

  Here, the processing at the time of mail transmission will be described in more detail. FIG. 8 is a flowchart illustrating an example of a mail transmission process procedure in the mobile phone 1 according to the present embodiment. Similar to the above standby mode, the SIM card 53a and the SIM card 53b are respectively mounted in the card slot 51a and the card slot 51b of the mobile phone 1, and the telephone numbers (mail addresses) thereof are “A” and “B”. ”Will be described.

  First, at the time of mail creation, the main control unit 21 recognizes the two SIM cards 53a and the SIM card 53b that are currently mounted, and the LCD control unit 33 displays the SIM card selection screen on the LCD 61 (step S61). In this SIM card selection screen, a telephone number (email address) registered in the currently installed SIM card and information related thereto are displayed, and the user selects any SIM card from among them by key operation, The key input unit 69 accepts the selection (YES in step S63).

  Then, the user inputs a destination mail address (step S65). The destination e-mail address may be input directly by character input by key operation. If a telephone book (address book) is registered in the SIM card 53, it is recorded in the SIM card 53 selected in step S63. You may select an e-mail address from the existing phone book. The destination mail address input or selected by the user by key operation or the like is received by the key input unit 69, transferred to the main control unit 21, and temporarily stored in the memory unit 41.

  Subsequently, the user inputs the subject and text of the mail by a key operation or the like, which is received by the key input unit 69 and temporarily stored in the memory unit 41 via the main control unit 21 (step S67). Subsequently, when the user gives an instruction to send an e-mail by pressing an operation button or the like, the key input unit 69 accepts the instruction (YES in step S69), and the main control unit 21 reads the SIM card 53 selected in step S63. The telephone number is read (step S71), and it is determined whether the telephone number is A or B (step S73).

  When the telephone number is A (A in step S73), the main control unit 21 first confirms in the wireless unit 5 whether or not the communication using the telephone number B is being performed (step S75). When the communication using the telephone number B is not performed (YES in step S75), the main control unit 21 transmits to the base station that the terminal is a terminal having the telephone number A via the wireless unit 5, and the destination. The mail address is sent to perform mail transmission processing (step S77). On the other hand, when the communication with the telephone number B is in progress (NO in step S75), the transmission process is stopped (step S85), and the state returns to the state before the mail transmission (step S69).

  When the telephone number is B (B in Step S73), the main control unit 21 first confirms whether the wireless unit 5 is performing communication with the telephone number A (Step S81). When communication using the telephone number A is not being performed (YES in step S81), the main control unit 21 transmits to the base station that the terminal is a terminal having the telephone number B via the wireless unit 5, and The mail address is sent to perform mail transmission processing (step S83). On the other hand, when the communication with the telephone number A is in progress (NO in step S81), the transmission process is stopped (step S85), and the state before the mail transmission (step S69) is returned.

  In this way, according to the SIM card 53 selected by the user in step S63, mail can be transmitted to the other party using the telephone number (mail address) registered in the SIM card 53. The communication fee at this time is charged to the telephone number of the SIM card 53 used at the time of mail transmission.

  If the created mail is not transmitted (NO in step S69), the LCD control unit 33 displays a screen for confirming whether or not to save the mail on the LCD 61 (step S87). When the key input unit 69 receives an instruction to save the mail (YES in step S87), the created mail is stored in the memory unit 41. Here, the telephone number of the selected SIM card 53 may be associated with the telephone number, or may be stored without being associated. In the latter case, when a stored mail is transmitted, a telephone number used for transmission is newly selected. When the key input unit 69 receives an instruction to discard the mail (NO in step S87), the created mail is discarded and the display returns to the SIM card selection screen display (step S61).

  As described above, according to the mobile phone 1 of the present embodiment, it is possible to select a billing destination contracted separately for each telephone number in accordance with the contents of the mail and the other party. Without adding a phone number, it is possible to simultaneously listen to each registered telephone number (mail address), and the same convenience as carrying a plurality of terminals can be realized. Furthermore, since it can be realized only by a device on the terminal side without modifying the processing on the network side, a new service can be provided while using an existing network as an infrastructure.

(Second embodiment)
The mobile phone 1 of the present embodiment is different from the above embodiment in that it registers the location of at least one phone number among a plurality of phone numbers and sets the reception timing of the paging channel signal for at least one phone number. The paging process is different. The configuration of the mobile phone 1 according to the present embodiment is the same as that shown in FIG.

  The mobile communication terminal (mobile phone 1) of the present embodiment is a mobile communication terminal capable of mounting at least one SIM card (SIM card 53) in which a plurality of telephone numbers are registered, and is registered in the SIM card. For each of a plurality of telephone numbers, an identification unit for identifying a plurality of telephone numbers (main control unit 21, card interface unit 43 and card slot 51), and making a location registration request to a base station (not shown), Location registration request unit (location registration unit 23) for notifying one of a plurality of telephone numbers as a reference number, and corresponding to the telephone number notified as a reference number from the base station after the location registration of the telephone number in the base station is completed. A system information receiving unit (location registration unit 23) that receives system information including paging channel allocation information, and a system information receiving unit A setting unit (position registration unit 23) for setting the reception timing of the paging channel from the base station based on the paging channel allocation information for the reference number of the system information, and paging for receiving the paging channel for the reference number according to the reception timing When the channel receiving unit (paging unit 25) and the paging channel receiving unit receive the paging channel, it is determined whether any of the plurality of telephone numbers identified by the identifying unit is included, and An incoming call detection unit (paging unit 25, incoming call unit 27) for detecting an incoming mail, and an incoming call storage unit (incoming unit 27, memory unit 41) for storing incoming information of a telephone number for which an incoming mail has been detected by the incoming call detection unit; .

  Specifically, in the present embodiment, the location registration unit 23 not only notifies the base station of each telephone number, but also notifies them that they are waiting together, and one of a plurality of telephone numbers. One as a reference number. For example, the location registration unit 23 uses the telephone number A of the SIM card 53a installed in the card slot 51a as the reference number of the terminal, and the telephone number B (three or more slots) of the SIM card 53b installed in the other card slot 51b. In this case, the base station is notified as incidental information of the telephone number A). In the telephone number information 90, the reception timing can be stored only in the telephone number registered as the reference number, or a flag indicating a representative telephone number can be stored.

  As a result, the network side can grasp that a plurality of terminals on the same system are simultaneously waiting on one terminal. Using this, it is defined that the timing of the paging channel corresponding to the telephone number A and the telephone number B is unified for the terminals. That is, a common paging channel is assigned to two telephone numbers A and B. On the terminal side, for example, as shown in FIG. 10, the paging timing of another telephone number B is processed in accordance with the telephone number A with the telephone number A as a reference.

  FIG. 9 is a flowchart illustrating an example of a procedure during the paging process of the mobile phone 1 of the present embodiment. Hereinafter, the paging process of the mobile phone 1 according to the present embodiment will be described with reference to FIG. 1, FIG. 9, and FIG.

  First, the paging unit 25 of the main control unit 21 monitors reception of the paging channel at a reception timing corresponding to the telephone number A in a predetermined cycle (step S111). When it is time to receive the paging channel (YES in step S111), the receiving circuit 13 of the wireless unit 5 is turned on to receive a paging channel signal (step S113). In this embodiment, the base station knows that the terminal is waiting at two telephone numbers A and B, and the paging channel signal is inserted with the telephone number that received the mail. It is transmitted to the mobile phone 1. Accordingly, the paging unit 25 determines whether or not the telephone number A is included in the paging channel signal. If the telephone number A is included (YES in step S115), the paging unit 25 sends a mail to the incoming unit 27 of the main control unit 21. Notify that there was an incoming call. The incoming call unit 27 receives the incoming call notification information 100 from the server via the wireless unit 5 (step S41). The incoming call unit 27 recognizes the telephone number (mail address) at which an incoming mail has been received based on the received incoming call notification information 100.

  On the other hand, if the paging channel signal does not include the telephone number A (NO in step S115), it is further determined whether the paging channel signal includes the telephone number B, and if the telephone number B is included ( YES in step S117), the incoming call unit 27 of the main control unit 21 is notified that an incoming mail has been received.

  The incoming call unit 27 receives the incoming call notification information 100 from the server via the wireless unit 5 (step S119). The incoming call unit 27 recognizes the telephone number (mail address) at which an incoming mail has been received based on the received incoming call notification information 100. If the telephone number B is not included in the paging channel signal (NO in step S117), the main control unit 21 turns off the receiving circuit 13 (step S121), returns to step S111, and waits for the next reception timing. (NO in step S111).

  In this way, it is possible to check whether or not there is a call from the base station at the timing based on the telephone number A, and to perform incoming processing of the telephone number that has been called. In the present embodiment, as shown in FIG. 10, the cellular phone 1 is in a sleep state during a time other than the time for checking the presence / absence of a paging channel signal at the timing based on the telephone number A. As a result, while waiting for two telephone numbers, it is possible to ensure a sleep time substantially equal to that for one telephone number. As a result, current consumption during standby can be suppressed.

  In step S119, when the incoming mail notification is recognized at either the telephone number A or the telephone number B, the incoming call unit 27 uses the notification function such as the speaker 67 to confirm that the user has received an incoming mail. Notification is made (step S123). In addition, the receiving unit 27 can display a message indicating that the incoming telephone number (mail address) is A or B on the LCD 61 to notify the user. Alternatively, it is also possible to notify and notify whether a mail has arrived and to which telephone number (mail address) by a predetermined lighting color or blinking pattern of an LED display (not shown). The incoming notification process in step S123 is performed according to the operation setting information at the time of incoming mail stored in the telephone number information 90 of FIG. In this way, different operation settings for incoming calls can be made for each telephone number.

  After that, when the user gives an instruction to receive an incoming mail, the key input unit 69 accepts the instruction (step S125), and the main control unit 21 sends an email acquisition request signal to the base station via the wireless unit 5. Send. This mail acquisition request signal includes information included in the above-described incoming notification information 100. The packet communication control unit 29 of the main control unit 21 acquires the mail transmitted from the base station via the reception circuit 13 of the wireless unit 5 (step S127). The packet data is received by the receiving circuit 13 via the antenna 11, amplified in signal level, converted to an arbitrary frequency, and digital demodulated, and then input to the baseband unit 7.

  The acquired mail is stored in the memory unit 41 in association with the telephone number. The received mail can be stored in the memory unit 41 by dividing the folder for each telephone number (mail address), or can be stored in one folder at a time. It is also possible to store each telephone number (mail address) in the SIM card. When the mail acquisition is completed, the packet communication control unit 29 sends a signal notifying that the acquisition is completed to the base station via the wireless unit 5 (step S129). The mail server deletes the mail that has received the notification of completion. The mail stored in the memory unit 41 can be sent to the LCD control unit 33 via the main control unit 21 and displayed as character information on the LCD 61 by a user operation, if necessary.

  As described above, according to the mobile phone 1 of the present embodiment, the timing based on a specific telephone number among a plurality of telephone numbers is set, and paging for each telephone number is simultaneously performed at this timing. Thus, not only can a plurality of telephone numbers be waited on, but a sleep time when the mobile phone 1 is on standby can be secured, and current consumption can be suppressed.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.

  For example, in the above embodiment, the configuration in which one telephone number is registered in one SIM card 53 is described, but the present invention is not limited to this. Even if a plurality of telephone numbers are registered in one SIM card 53, the present invention can be realized. In this case, terminal information 80 of a plurality of telephone numbers is recorded in one SIM card 53 so as to be identifiable, and the terminal information 80 of a plurality of telephone numbers is identified and read from the SIM card 53 in the mobile phone 1. be able to.

  In the above embodiment, the configuration in which the two SIM cards 53 are mounted on the mobile phone 1 has been described. However, the present invention is not limited to this, and a process similar to that described above is performed by mounting a plurality of SIM cards. It is also possible to perform.

  In the above embodiment, a case where one mail address is registered for one telephone number has been described. However, one telephone can be registered by registering a plurality of mail addresses for one telephone number on the server side. It is possible to send and receive mails of a plurality of mail addresses with respect to the number. On the server side, when mail arrives at a plurality of registered mail addresses, an incoming notification is sent to the terminal having the corresponding telephone number. Regarding email transmission via other business operators or the Internet, when one main email address is registered in advance in the server from multiple email addresses, and an email is sent from the terminal with the corresponding phone number The electronic mail is transmitted with the registered main mail address as the transmission source.
