  FIG. 2 is a diagram illustrating an example of a data structure of message information registered in the message storage unit 38. FIG. 2 shows an example in which n message information items 1 to n are registered in the message storage unit 38.

  The message information shown in the figure is obtained by adding message management information for managing the message message to the message message inputted by voice by the user. Specifically, the p-th message information (Mp) registered includes message management information and a message message as data items. The message management information includes data items such as a message registration telephone number (Np), a message registration date (Dip), a last message reproduction date (Dop), and a personal identification number (PWp). Note that the personal identification number (PWp) is set only for message registration using a personal identification number, and is a space in the case of message registration not using a personal identification number.

  FIG. 3 is a flowchart showing an example of a message registration process performed by the message dial center device 3 of the present embodiment.

  The message registration process is a process of registering (storing) the message message transmitted from the user terminal 1 in the message storage unit 38 of the message dial center device 3. In accordance with the guidance transmitted from the message dial center device 3, the user designates his / her telephone number or the phone number of the other party to be contacted, and registers the message message in the message dial center device 3.

  In the present embodiment, the message registration unit 35 registers the message message corresponding to the telephone number of the disaster area and the telephone number other than the disaster area without determining whether the telephone number is the disaster area. That is, the message message registered in the present embodiment is not limited to the one corresponding to the telephone number of the fixed telephone in the disaster area, but the telephone number of the fixed telephone other than the disaster area and the telephone number of the mobile terminal (smartphone or the like). It corresponds to and is registered.

  For example, a user in a disaster area can register a message message by specifying a telephone number of his / her mobile terminal, and can tell his / her family and friends that it is safe. In addition, the user specifies the telephone number of the other party's landline or mobile terminal that he / she wants to contact in the disaster area or outside the disaster area (for example, near the disaster area, etc.) You can register a message.

  In the illustrated message registration process, a call transmitted from the user terminal 1 is received by the call processing unit 31 of the message dial center apparatus 3, and after the call processing unit 31 performs the call processing, the user receives guidance. Therefore, it is performed when message registration (message recording) is selected. The guidance output unit 34 transmits a message registration guidance to the user terminal 1 via the call processing unit 31, and prompts the user to input various operations (such as input of a telephone number and a message message). Note that transmission / reception of data between the message processing unit 33 and the user terminal 1 is performed via the call processing unit 31.

  The message registration unit 35 of the message dial center device 3 receives the message registration request transmitted from the user terminal 1 (step S11). If the message registration request is message registration using a password, the password transmitted from the user terminal 1 is received. The user inputs the personal identification number into the user terminal 1 in accordance with the guidance transmitted by the guidance output unit 34.

  And the message registration part 35 ensures the storage area | region of the message information (Mp) corresponding to the message registration request received by step S11 in the message memory | storage part 38 (step S12). And the message registration part 35 registers the message registration telephone number (Np) transmitted from the user terminal 1 in the storage area of the message memory | storage part 38 ensured by S12 (step S13). Specifically, it is registered as message management information of the message information shown in FIG.

  Then, the message registration unit 35 determines whether or not the password is received together with the message registration request in step S11 (step S14). If the password is received (step S14: YES), the password (PWp) ) Is registered in the message storage unit 38 as message management information (step S15). On the other hand, if the code number is not received, that is, if the message registration request does not use the code number (step S14: NO), the message registration unit 35 proceeds to step S16.

  Then, the user inputs a message message to the user terminal 1 according to the guidance transmitted by the guidance output unit 34, and the user terminal 1 transmits the input message message to the message dial center device 3.

  When the message registration unit 35 receives the message message transmitted from the user terminal 1, the message registration unit 35 converts the data using the voice data conversion unit 32, and registers the converted message message in the message storage unit 38 (step S16). That is, the message registration unit 35 records a message message. The audio data conversion unit 32 converts the normal streaming audio file (message message) transmitted from the user terminal 1 into, for example, a WAV (RIFF waveform Audio Format) file format, and the message registration unit 35 converts the file. The message message is stored in the message storage unit 38 in the file format.

  In addition, the message registration unit 35 sets today's date (Dt) as the message registration date (Dip) and the last message reproduction date (Dop) as message management information of the message, and registers the message in the message storage unit 38 (step). S17). Thus, in this embodiment, the date of the message registration date is set as the last message reproduction date (Dop) at the time of message registration.

  By the message registration process described above, the message storage unit 38 of the message dial center device 3 stores the message message of the user in association with the message management information such as the telephone number and the last message reproduction date (Dop). 38.

  FIG. 4 is a flowchart showing an example of a message reproduction process performed by the message dial center apparatus 3 of the present embodiment.

  The message reproduction process is a process of reproducing a message message of message information stored in the message storage unit 38 in response to a request from the user terminal 1. The user listens to the message message by designating the telephone number of the other party who wants to hear the message according to the guidance transmitted from the message dial center device 3.

  In the message reproduction process shown in the figure, a call transmitted from the user terminal 1 is received by the call processing unit 31 of the message dial center apparatus 3, and after the call processing unit 31 performs the call processing, the user follows the guidance. Performed when message playback is selected. The guidance output unit 34 transmits message playback guidance to the user terminal 1 via the call processing unit 31 and prompts the user to input various operations (such as input of a telephone number). Note that transmission / reception of data between the message processing unit 33 and the user terminal 1 is performed via the call processing unit 31.

  The message reproduction unit 36 of the message dial center device 3 receives the message reproduction request transmitted from the user terminal 1 (step S21). It is assumed that a telephone number is specified in the message playback request. If the message playback request is a message playback request using a password, the password transmitted from the user terminal 1 is received. The user inputs the personal identification number into the user terminal 1 in accordance with the guidance transmitted by the guidance output unit 34.

  Then, the message reproduction unit 36 determines whether or not message information (Mp) having the same message registration telephone number (Np) as the telephone number specified in the message reproduction request exists in the message storage unit 38 (step S22). ).

  When the message information (Mp) that matches the designated telephone number does not exist in the message storage unit 38 (step S22: mismatch), the message reproduction unit 36 indicates that the message message of the designated phone number is not registered. An error message (voice message) is transmitted to the user terminal 1, and the process returns to step S21 to prompt the user to re-enter the telephone number.

  On the other hand, when the message information (Mp) that matches the designated telephone number exists in the message storage unit 38 (step S22: match), the message playback unit 36 has received the code number together with the message playback request in S21. Is determined (step S23). If the code number has not been received, that is, if the message reproduction request does not use the code number (step S23: NO), the message reproduction unit 36 proceeds to step S25.

  On the other hand, when the code number is received (step S23: YES), the message playback unit 36 determines whether or not the received code number matches the code number set in the message storage unit 38 at the time of message registration (step S23). S24). Specifically, the message playback unit 36 reads the message information (Mp) of the message registered telephone number (Np) that matches the telephone number specified in S21 from the message storage unit 38, and sets the message information (Mp). It is determined whether or not the received personal identification number (PWp) matches the personal identification number received in S21.

  If the passwords do not match (step S24: mismatch), the message playback unit 36 sends an error message to the user terminal 1 indicating that the specified password is incorrect, and prompts the user to re-enter the password. In order to prompt, return to step S21.

  When the code numbers match (step S24: match), the message playback unit 36 plays back and uses the message message of the message information (Mp) of the telephone number specified in S21 (that is, the registered telephone number (Np)). Is transmitted to the person terminal 1 (step S25). In this embodiment, when the message message is reproduced, the message reproduction unit 36 converts the voice data (message message) stored in the message storage unit 38 after being converted into a file format such as WAV in step S16 of FIG. Then, the audio data conversion unit 32 is used to perform reverse conversion into a normal streaming audio file.

  Thereby, the reproduced message message is sent to the user terminal 1, and the user can listen to the message message.

  Then, the message playback unit 36 sets today's date (Dt) as the last message playback date (Dop) of the message information (Mp) read from the message storage unit 38, and updates the message information (Mp) (step). S26).

  By the message reproduction process described above, the message message stored in the message storage unit 38 of the message dial center device 3 is reproduced, and the last message reproduction date added to the message message is reproduced every time the message message is reproduced. Updated.

  In this embodiment, as shown in FIG. 2, the message playback date is one of the last message playback dates, and the date of the last message playback date is updated every time playback is performed. It is not limited. For example, the message management information may include a plurality of message reproduction date data items, and the message reproduction date may be added and stored each time reproduction is performed.

  FIG. 5 is a flowchart showing an example of message deletion processing performed by the message dial center device 3 of the present embodiment. This processing is executed at a predetermined timing. For example, the predetermined timing may be a fixed time (such as midnight) once a day.

  In the illustrated example, it is assumed that there are n message information (Mp) registered in the message storage unit 38 at the time of execution of this process.

  First, the message deletion unit 37 sets 1 to p (step S31).

  Then, the message deletion unit 37 determines whether p is smaller than n + 1 (step S32). If p matches n + 1, that is, all of the n message information stored in the message storage unit 38. When the processing of steps S33 to S35 is finished (step S32: NO), this processing ends.

  When p is smaller than n + 1 (step S32: YES), the p-th message information (Mp) is read from the message storage unit 38, and the last message reproduction date (Dop) of the message information (Mp) is referred to (step S33). .

  Then, the message deletion unit 37 determines whether today's date (Dt) is equal to “last message reproduction date (Dop) + message storage period (T) +1” (step S34). The message storage period (T) is a predetermined number of days set in advance, and is a period in which message information is stored in the message storage unit 38 starting from the last message reproduction date.

  When today's date (Dt) is equal to “last message playback date (Dop) + message storage period (T) +1”, that is, when the message storage period (T) has elapsed from the last message playback date (step S34: YES) ), The message deletion unit 37 deletes the message information (Mp) from the message storage unit 38 (step S35).

  On the other hand, if today's date (Dt) is not equal to “last message playback date (Dop) + message storage period (T) +1”, that is, if message storage period (T) has not elapsed since the last message playback date (Step S34: NO), the message deletion unit 37 proceeds to Step S36 without deleting the message information (Mp).

  Then, the message deletion unit 37 adds 1 to p (step S36), proceeds to step S31, and repeats the subsequent processing until p matches n + 1.

  With the message deletion process described above, all message information that has passed the message storage period (T) is deleted on the basis of the date when the message message was last reproduced.

  When the message management information of the message information includes a plurality of message reproduction date data items, and the message reproduction date is added and stored every time reproduction is performed, the message deletion unit 37 sets the message reproduction date that has been set. From the inside, the last (latest) message playback date is the last message playback date.

  In the present embodiment described above, it is determined whether or not each message information (message message) registered in the message storage unit 38 is to be deleted using the last message playback date that was last played, and the message that has been determined to be deleted is determined. The message is deleted from the message storage unit 38. In other words, in the present embodiment, it is determined whether or not to delete based on the last message reproduction date.

  Conventionally, the message information storage period is uniformly limited, and when the uniform storage period expires, it is automatically deleted, and if the playback request continues after the storage period expires, the user can It is necessary to repeat the operation for recording.

  On the other hand, in this embodiment, since the storage period is flexibly set for each message message in accordance with the reproduction status or necessity of the message message with reference to the last message reproduction date, the user can There is no need to re-register, and convenience for the user can be improved. That is, in the present embodiment, the message storage period is not uniform, and the message can be stored according to the reproduction frequency for each message.

  Further, in the present embodiment, messages that are not reproduced are deleted after a predetermined message storage period (T) has elapsed, and therefore the data storage area of the message storage unit 38 is shortened by shortening the message storage period (T). It can be expected to avoid early depletion.

  In this embodiment, the message message corresponding to the telephone number of the disaster area and the telephone number other than the disaster area is registered without determining whether the telephone number is the disaster area.

  Conventionally, the telephone numbers that can be registered for messages are limited to the landline telephone numbers in the disaster area, and the area code is used to determine whether the message is registered from the landline telephone numbers in the disaster area. This is done depending on whether the area number is in the affected area. However, the area code and administrative area of the affected area do not always match. In addition, when a wide-area disaster occurs in a metropolitan area with a dense population, it is assumed that registration requests will be concentrated in a short time, so it is essential to minimize the time required for each process. Processing across or between multiple operators should be avoided. In addition, considering that the number of mobile terminals is increasing dramatically and there are not a few victims who do not have a landline telephone, it is required that the 0A0 number band be subject to the message registration number in the future. In this case, processing linked to GPS position information is assumed, but cooperation with other systems such as a position information database is required, complicating message registration processing, and increasing the processing load on the system.

  On the other hand, in this embodiment, it is possible to reduce the processing load of the message registration process by not determining whether or not the telephone number is in the disaster area. Without being limited to the above, even if the telephone number of the landline telephone and the portable terminal other than the stricken area is the target of the message registration telephone number, the convenience of the user can be improved.

  In addition, this invention is not limited to the said embodiment, Many deformation | transformation and application are possible within the range of the summary.
