If the electric field strength detecting means does not detect a predetermined first electric field strength or higher, the mail is not transmitted. Subsequently, when the electric field strength detecting means detects the first electric field strength or higher, the mail is automatically sent. The mail transmitting / receiving means is controlled so as to transmit, the first electric field strength is detected and the mail is transmitted, and when the number of transmission failures reaches a predetermined number of times, it is greater than the first electric field strength. Control is performed such that mail is automatically transmitted using the second electric field strength as a threshold value.

  According to the fourth aspect of the present invention, when a mail transmission instruction is issued, mail transmission is not performed when the electric field strength is lower than a predetermined value, so that the user need not perform a useless mail transmission operation. In addition, since the mail is automatically transmitted when the electric field strength exceeds a predetermined value, it is not necessary for the user to perform a mail transmission operation.

  According to the fifth aspect of the present invention, when a mail transmission instruction is given, mail transmission is not performed unless the electric field strength is the first, so that the user does not need to perform unnecessary mail transmission. In addition, since the mail is automatically transmitted if the first electric field strength is used for mail transmission, it is not necessary for the user to perform the mail transmission operation one by one.

  A control circuit (control unit) 36 is connected to each of the communication unit 12, the baseband unit 14, and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 controls the audio codec 20 of the baseband unit 14, and the audio codec 20 changes the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30. A ROM 37 is connected to the control circuit 36 and controls each part based on a system program stored in the ROM 37.

  An input unit 44 is connected to the control circuit 36. The input unit 44 includes a numeric keypad 48 for inputting a telephone number, composing mail, and the like, a call key 50 for operating the start of a call, a cut key 52 for terminating a call, and a function key 54. ing.

  A RAM (Randum Access Memory) 38 stores mail created by an input operation from the input unit 44, and stores, for example, a plurality of mails including a mail title, a mail text, a mail address of a mail transmission destination, and the like. . The RAM 38 also stores telephone directory data, and stores a plurality of destination information including the name, phone number, and mail address of the destination. The destination mail address of the outgoing mail can also be selected from this telephone directory data. In addition, it has a reservation transmission flag and a counter, and the reservation transmission flag is a flag for setting whether or not to automatically transmit mail when the mobile phone device moves from outside the service area to within the service area. On the other hand, the counter is a counter that counts the number of times the mail has been automatically sent and automatically sent.

  The apparatus of this embodiment has such a configuration. Next, the operation of the apparatus of this embodiment will be described below.

  First, the first embodiment will be described below.

  In the first embodiment, after a mail is created, if there is an email transmission instruction and the mobile phone device is out of the service area, the user will automatically create it when the mobile phone device enters the service area by giving a transmission reservation instruction. Is to send the mail. In addition, when mail transmission fails even though it has entered the area, the mail is transmitted until the predetermined electric field strength is reached.

  In step S1 of FIG. 2, a mail is created by input from the input unit 44. In the subsequent step S2, the created mail is temporarily stored in the RAM 38. Note that the created mail may be temporarily stored in a buffer memory or a folder that stores a plurality of outgoing mails, such as a mail transmission folder.

  In step S3, when the control circuit 36 determines that there is a mail transmission instruction from the input unit 44, the process proceeds to step S4. At this time, the display 42 displays an inquiry as to whether or not to send a mail as shown in FIG.

  In step S4, based on the electric field strength measured by the baseband unit 14, the control circuit 36 is out of service area (the mobile phone device is in a position where radio waves from the base station do not reach, or there is no electric field strength that can be transmitted / received). ), The process proceeds to step S7; otherwise, the process proceeds to step S5. At this time, the display 42 is displayed to indicate that it is out of service area as shown in FIG.

  In step S5, the control circuit 36 controls the telephone communication unit 12 and the baseband unit 14 to transmit the mail text created in steps S1 and S2 and stored in the RAM 38, and the process proceeds to step S6.

  In step S6, when the control circuit 36 determines that the transmission is successful, the control circuit 36 ends the process. Otherwise, the process returns to step S3.

  In step S 7, the control circuit 36 controls the display 42 to display “out of service area” on the display 42. For example, the characters “out of range” are displayed at the display position of the antenna mark on the display 42, and the process proceeds to step S8.

  In step S8, the control circuit 36 rejects acceptance of the mail transmission instruction in step S3, controls not to perform mail transmission, and proceeds to step S9.

  In step S9, if the control circuit 36 determines that there is a reservation transmission instruction from the input unit 44, the process proceeds to step S10, and if not, the process proceeds to step S11. At this time, an inquiry display as to whether or not to make a reservation transmission is displayed on the display 42 as shown in FIG.

  In step S10, the control circuit 36 turns on the reservation transmission flag stored in the RAM 38, that is, automatically enters a state in which a mail is transmitted when entering the area, and proceeds to step S11.

  In step S11, if the control circuit 36 determines that the reserved transmission flag stored in the RAM 38 is on, the control circuit 36 proceeds to step S15, and if not, proceeds to step S12.

  In step S12, if the control circuit 36 determines that there is a mail transmission instruction from the input unit 44, the process proceeds to step S13, and if not, the process returns to step S9.

  In step S13, the control circuit 36 controls the telephone communication unit 12 and the baseband unit 14 to transmit the mail text created in steps S1 and S2 and stored in the RAM 38, and the process proceeds to step S14.

  In step S14, when the control circuit 36 determines that the transmission is successful, the control circuit 36 ends the process. Otherwise, the control circuit 36 returns the process to step S3.

  In step S15, based on the electric field strength measured by the baseband unit 14, the control circuit 36 is in a range (the mobile phone device is in a position where radio waves reach from the base station, or there is electric field strength that can be transmitted and received). If it is determined that there is, the process proceeds to step S16, and if not, the process proceeds to step S12. At this time, as shown in FIG. 3 (d), the display 42 displays a message indicating that the e-mail is to be transmitted because it is within range.

  In step S16, the control circuit 36 transmits the mail stored in the RAM 38 as in step S11.

  In step S17, if the control circuit 36 determines that the mail has been transmitted normally, the control circuit 36 ends the process. If not, the process proceeds to step S18.

  In step S18, the control circuit 36 counts up the counter stored in the RAM 38 and advances the process to step S19.

  In step S19, when the control circuit 36 determines that the counter stored in the RAM 38 has counted three times, the control circuit 36 proceeds to step S20, and otherwise returns to step S11.

  In step S20, the control circuit 36 has a predetermined electric field strength determined in advance based on the electric field strength measured by the baseband unit 14 (for example, the electric field strength sufficient to send and receive mail and is displayed on the display 42. If, for example, four antennas are displayed, the process proceeds to step S21 if it is determined that the electric field intensity corresponds to the display of all four antennas. At this time, the display 42 displays as shown in FIG. Further, the predetermined electric field strength may be set by the user or may be a value already set at the time of factory shipment. The electric field strength may not be the electric field strength corresponding to the display of all four antennas, but may be the electric field strength corresponding to the display of two or three antennas.

  In addition, if the electric field strength is not a predetermined value in step S20, the mail may be transmitted based on the user's mail transmission instruction.

  In step S21, the control circuit 36 performs mail transmission control similarly to step S13, and proceeds to step S22.

  In step S22, if the control circuit 36 determines that the mail has been transmitted normally, the control circuit 36 ends the process. If not, the process returns to step S20.

  As described above, in the first embodiment apparatus, if the user is out of service area when the mail transmission instruction is given, the mail transmission is not performed. Subsequently, a mail is automatically transmitted when the mobile phone device enters the area. For this reason, useless mail transmission is not necessary. Further, since the mail is automatically transmitted when the mobile phone device enters the area from outside the service area, it is not necessary for the user to perform a mail transmission operation. In addition, when a certain number of email transmission failures occur after entering the service area, a mail is automatically sent when a predetermined electric field strength (for example, the maximum number of antennas is displayed) is reached. It is possible to avoid useless mail transmission in a state where it is not possible to transmit.

  Next, the second embodiment apparatus will be described. The difference between the first embodiment and the second embodiment is in steps S3 to S8 in FIG. 2 and steps S3 to S7 in FIG. Since other parts perform the same operation, description thereof is omitted.

  When a mail is created in step S1 in FIG. 4 and the mail created in step S2 is stored in the RAM 38, in step S3, the control circuit 36 is out of service area (based on the electric field strength measured by the baseband unit 14). If it is determined that the mobile phone device is in a position where radio waves from the base station do not reach or is not in an electric field intensity enough to be transmitted / received, the process proceeds to step S7, and if not, the process proceeds to step S4. . At this time, the display 42 is displayed to indicate that it is out of service area as shown in FIG.

  In step S4, when the control circuit 36 determines that there is a mail transmission instruction from the input unit 44, the process proceeds to step S5.

  In the subsequent step S5, the control circuit 36 controls the telephone communication unit 12 and the baseband unit 14 to transmit the mail text created in the steps S1 and S2 and stored in the RAM 38, and the process proceeds to step S6.

  In step S6, when the control circuit 36 determines that the transmission is successful, the control circuit 36 ends the process. Otherwise, the process returns to step S3.

  In step S 7, the control circuit 36 controls the display 42 to display “out of service area” on the display 42. For example, the characters “out of range” are displayed at the display position of the antenna mark on the display 42, and the process proceeds to step S8.

  The subsequent steps S8 to S21 correspond to steps S9 to S22 in FIG.

  In this way, in the second embodiment apparatus, when the electric field strength after the mail creation is at the out-of-service level, the apparatus waits until the electric field strength reaches the in-range level based on the user's reservation transmission instruction. When the level is reached, the mail stored in the RAM 38 is automatically transmitted, so that it is not necessary for the user to repeatedly perform the mail transmission instruction operation. In addition, even if the electric field strength is within the range, if the e-mail transmission fails a predetermined number of times, the e-mail is transmitted when the electric field intensity corresponding to the four antenna marks is displayed. That is, since the mail is transmitted when the optimal mail transmission environment for the mobile phone device is reached, it is possible to avoid unnecessary mail transmission.

  In this embodiment, when the display 42 is switched from “out of service area” display to antenna mark display, the mail is transmitted. However, when the electric field intensity at a level at which mail can be transmitted is reached, a preset value is set. It is also possible to send a mail when the electric field strength is reached, when the number of antenna marks displayed on the display 42 reaches a predetermined number, or when the maximum number of antenna marks is displayed on the display 42. good.
