  FIG. 5 shows a communication quality measurement sequence using the application 31 of the mobile phone 10. In this sequence, first, when the user starts the application 31, the measurement management unit 61 displays the screen D1 of FIG. 6 in step S1. In this screen, when the user operates the operation unit 12 to select each function 1 to 7 displayed on the display device 13, the screen transitions to a screen for executing each function. Here, “1. HTTP measurement mode” is a mode for measuring response time of communication using HTTP communication, and “2. SMS measurement mode” and “3. MMS measurement mode” are SMS and This is a mode for measuring the delivery time of MMS mail communication. Further, “4. SMS / MMS measurement mode” is a measurement mode for performing both SMS measurement and MMS measurement, and “5. All measurement mode” is a mode for performing measurement for all of HTTP, SMS, and MMS. It is. The measurement in each measurement mode is repeatedly performed at the time interval set on the screen “D4. Also, the SMS / MMS transmission destination and the HTTP communication access destination are determined at random from a plurality of transmission destinations set on the screen D4 at the same time, and measurement is performed.

  Returning to the screen D1 in FIG. 6, when the user selects “7. Setting”, as shown in the screen D4 in FIG. Measurement time intervals in the measurement mode, settings of a plurality of SMS / MMS transmission destinations, a plurality of access destinations of HTTP communication, transmission timing of measurement reports, and the like are displayed, and settings can be made for each item. Here, the set local telephone number and model name become part of the data of the measurement report transmitted after the measurement. In addition, the measurement report transmission timing is set to be transmitted when there are two or more measurement reports to be transmitted. When the user selects “6. Device information”, as shown in the screen D3 of FIG. 6, the local phone number of the mobile phone 10 set on the screen D4 of “7. In addition to the model name, information on the mobile phone such as the electric field strength of the radio wave received by the mobile phone 10 and the latitude and longitude indicating the current position is displayed.

  Returning to FIG. 5, when the user selects “5. All measurement modes”, in step S <b> 2, the measurement management unit 61 displays the screen D <b> 2 of FIG. 6, and performs measurement for all of HTTP, SMS, and MMS. Measurement mode. On the screen D2, the current time, the set measurement interval, the number of successes and failures of the measurement performed so far, the number of successful transmissions and failures of the measurement report, the number of times outside the communication range at the time of measurement, the current measurement The status of whether or not there is, the access speed in the last measurement, and the like are displayed. Even when a measurement mode other than the all measurement mode is selected, a screen having the same contents as the screen D2 is displayed.

  Returning to FIG. 5, when the set time elapses, the timer unit 34 notifies the measurement management unit 61 that the set time has elapsed. The measurement management unit 61 notified of the elapse of the timer time first executes the mail transmission measurement report processing S3 for measuring the SMS and MMS mail transmission and transmitting the report, and 10 minutes later, the SMS and the MMS A mail reception measurement report process S4 is performed for measuring the MMS mail reception and transmitting the report. Further, 10 minutes later, HTTP communication measurement report processing S5 is performed for measuring the HTTP communication and transmitting the report. Below, each of these measurement process S3-S5 is demonstrated.

  In the mail transmission measurement report process S3, as shown in FIG. 7, first, the measurement management unit 61 requests the SMS / MMS transmission measurement process S31 from the mail communication measurement unit 62, and the mail communication measurement unit 62 executes the SMS / MMS. The transmission measurement process S31 is started. In the SMS / MMS transmission measurement process S31, as shown in FIG. 8, first, it is confirmed whether or not the time synchronization process is completed. Here, the time synchronization process is a process that is performed only once after the application 31 is activated, and the time synchronization process is performed only when the time synchronization process has not yet been performed. In this case, since it is determined that the time synchronization process is not performed, the mail communication measurement unit 62 requests the timer unit 34 for the time synchronization process. The timer unit 34 requested to perform time synchronization processing performs time synchronization processing S11. In the time synchronization processing S11, as shown in FIG. 9, first, the timer unit 34 acquires and stores the time T1 of the clock inside the mobile phone 10, and the NTP (Network Time) is transmitted via the transmission / reception unit 22 and the gateway server 45. The server time ST is acquired from the quality management server 52 having a Protocol function. The timer unit 34 that has acquired the server time acquires again the time T2 of the clock inside the mobile phone 10, and calculates the time difference DT of the mobile phone 10. Here, the time difference DT is calculated by the following equation in order to consider the communication time with the quality management server 52.

算出された時刻のずれＤＴは、携帯電話１０の内部の時計の現在時刻に加えられることにより、内部の時計の時刻が補正される。

The calculated time difference DT is added to the current time of the internal clock of the mobile phone 10 to correct the time of the internal clock.

  Returning to FIG. 8, the timer unit 34 that has finished the time synchronization process S <b> 11 notifies the mail communication measurement unit 62 of the completion of the time synchronization process. The mail communication measuring unit 62 that has received the completion of the time synchronization process requests the environment measuring unit 65 for the environment measuring process S12 in order to measure the current communication environment of the mobile phone 10. The environment measurement unit 65 that has received the request for the environment measurement process S12 performs the environment measurement process S12. In the environment measurement process S12, as shown in FIG. 10, first, the environment measurement unit 65 requests the current position acquisition unit 33 to acquire the current position. The current position acquisition unit 33 requested to acquire the current position receives the radio wave from the GPS satellite by the GPS radio wave reception process, and calculates the current position. The calculated current position is notified to the environment measurement unit 65. Subsequently, the environment measuring unit 65 acquires the current electric field strength value held by the electric field intensity acquiring unit 32 from the electric field intensity acquiring unit 32, and further, the battery remaining amount measuring unit from the battery remaining amount measuring unit 35. The value of the remaining battery level held by 35 is acquired. Finally, the communication state of the mobile phone 10 is acquired from the communication state management unit 36 that manages the communication state of the mobile phone 10, and the environment measurement process S12 is ended.

  Returning to FIG. 8, when the environment measurement process S <b> 12 ends, the environment measurement unit 65 notifies the mail communication measurement unit 62 of the measured environment measurement value. The mail communication measuring unit 62 determines whether measurement is possible from the notified environmental measurement value. Here, the requirements for enabling measurement are that the mobile phone 10 is not communicating from the acquired communication state and that the acquired value of the electric field strength is equal to or greater than a predetermined value. If it is not determined that measurement is possible, the SMS / MMS transmission measurement process S31 is terminated without creating or transmitting the mail. On the other hand, when it is determined that measurement is possible, a transmission time for writing in the mail is acquired from the timer unit 34, and a transmission mail is created. Here, as shown in FIG. 11, the text of the created mail includes the acquired transmission time, the preset local phone number and model name, the latitude and longitude that are the acquired current position, and the electric field. The strength, the remaining battery level, and a mail transmission destination address are described. The mail transmission destination address is selected and determined at random from a plurality of SMS transmission destination addresses set in advance. Here, it is assumed that the address of the mobile phone 44 is selected. Returning to FIG. 8, the created mail is transmitted to the mobile phone 44 via the transmission / reception unit 22 and the SMS server 43 as an SMS mail.

  After completing the transmission of the SMS mail, the mail communication measuring unit 62 acquires the time as in the case of the SMS and transmits a plurality of MMSs whose mail destination addresses are set in advance in order to transmit the MMS mail. Randomly selected from the destination addresses. Here, it is assumed that the quality management server 52 is selected as the mail transmission destination. Subsequently, as in the case of SMS, a mail to be transmitted is created. The text of the created mail has almost the same content as that of the SMS mail, but the time acquired anew as the transmission time is described, and the address of the quality management server 52 is described as the transmission destination address. Thereafter, the MMS mail is transmitted from the transmission / reception unit 22 and converted into an e-mail by the MMS server 47. The converted mail is delivered to the quality management server 52 via the Internet network 50. In the quality management server 52, an email reception process S13 is performed.

  In the e-mail reception process S13, as shown in FIG. 12, in the mail communication unit 74 of the quality management server 52 that has received the e-mail, first the reception time is recorded in the e-mail, and then whether it is a measurement e-mail. Judgment is made. Whether or not it is a measurement mail is determined by whether or not a predetermined character indicating that it is a measurement mail is included in the title or text. Here, if it is not a measurement mail, the process is terminated as it is. On the other hand, in the case of a measurement mail, the mail communication unit 74 requests the mail delivery time calculation unit 75 to calculate the mail delivery time. The mail delivery time calculation unit 75 requested to calculate the mail delivery time calculates the mail delivery time from the transmission time and the reception time described in the mail, and notifies the mail communication unit 74 of the delivery time. The mail communication unit 74 notified of the delivery time notifies the statistical processing unit 76 of the content described in the body of the mail and the measurement data that is the notified delivery time. The statistical processing unit 76 performs statistical processing together with the measurement data received and accumulated by the measurement data receiving unit 73. Here, when the statistical processing unit 76 detects data indicating an abnormality such as a number of communication failures in the same region, the statistical processing unit 76 notifies the abnormality notification unit 77 that there is an abnormality, and has received the notification. The abnormality notification unit 77 notifies the administrator of the abnormality.

  Returning to FIG. 7, when the SMS / MMS transmission measurement process S31 in the mobile phone 10 is completed, the mail communication measurement unit 62 completes the SMS / MMS transmission measurement process S31 together with the SMS and MMS mail transmission results. 61 is notified. Here, the measurement management unit 61 determines whether transmission of SMS or MMS mail has failed. If it is determined that transmission of at least one of SMS and MMS has failed, the measurement report processing unit 64 is requested to process the measurement report. The measurement report processing unit 64 requested to process the measurement report performs measurement report processing S6.

  In the measurement report process S6, as shown in FIG. 13, first, a measurement report for notifying the quality management server 52 is created based on the measurement data notified accompanying the request for the measurement report process. Here, since the created measurement report is a measurement report when mail transmission fails as shown in FIG. 14, only information that can be acquired on the mail transmission side is described. Specifically, the type of whether the failed mail is SMS or MMS, the address of the mobile phone 10 that is the transmission source, the error code, the transmission time that is the content described in the mail text, etc. are described. Yes. Here, the error code is an identifier indicating the cause of the failure to send the mail.

  Next, since transmission of the measurement report is set to be transmitted when there are two or more reports to be transmitted on the screen D4 in FIG. Determine if there is a report. Here, when there is an untransmitted measurement report, both the untransmitted measurement report and the current transmission failure measurement report are transmitted. The transmitted measurement report is transmitted to the quality management server 52 through the transmission / reception unit 22 and the gateway server 45 by HTTP communication. The measurement data receiving unit 73 of the quality management server 52 receives the measurement report and notifies the statistical processing unit 76 of the measurement data described in the measurement report. When the statistical processing unit 76 performs statistical processing together with the already accumulated measurement data and detects data indicating an abnormality such as a number of failed communications in the same region, as in the email reception processing S13. In this case, the abnormality notification unit 77 is notified that there is an abnormality, and the abnormality notification unit 77 that has received the notification notifies the administrator of the abnormality. On the other hand, when transmission of a measurement report fails, it accumulate | stores as an unsent report and is transmitted with another measurement report in the next transmission. Further, even if there is no untransmitted measurement report, it is accumulated as an untransmitted measurement report until another measurement report is created. Returning to FIG. 7, the measurement report processing unit 64 that has finished the measurement report processing S6 notifies the measurement management unit 61 of the completion of the measurement report processing.

  Next, the process of the mail reception measurement report process S4 of FIG. 5 will be described. In the mail reception measurement report processing S4, as shown in FIG. 15, first, the measurement management unit 61 requests the mail communication measurement unit 62 to perform SMS / MMS reception measurement processing. The mail communication measuring unit 62 that has received the request for the SMS / MMS reception measurement processing performs measurement processing when receiving the SMS measurement email and performs measurement when receiving the SMS reception measurement state and the MMS measurement email. Set to “MMS reception measurement state” for processing. The processing in this state is described in FIGS. 16 and 18 as SMS reception measurement processing S41 and MMS reception measurement processing S42, respectively. In FIG. 16, the mobile phone 44 performs environment measurement processing S <b> 12 and SMS mail creation processing in the same manner as the SMS / MMS transmission measurement processing S <b> 31 described above, and transmits a measurement mail to the mobile phone 10. The transmitted mail is received by the mail communication measuring unit 62 via the SMS server 43 and the transmitting / receiving unit 22 of the mobile phone 10. The mail communication measuring unit 62 that has received the mail first obtains the current time from the timer unit 34, writes it in the mail as the reception time, and subsequently determines whether the content of the mail is a command.

  Here, the command is a command to the application 31 that is used when the application 31 is controlled from the outside via mail. With this command, even when the cellular phone 10 is not at hand, it is possible to execute each measurement mode and change the setting of the measurement interval and the mail address of the report transmission destination.

  If it is determined that the command is a command, the mail communication measuring unit 62 executes the processing of the command and continues to wait for mail reception. If it is determined that it is not a command, it is determined whether or not it is a measurement mail. Whether or not it is a measurement mail is determined by whether or not a predetermined character representing a command is included in the title or body. Here, in the case of not being a measurement mail, as in the case of command processing, the mail reception wait state is continued. On the other hand, in the case of a measurement mail, the mail communication measurement unit 62 calculates a mail delivery time. Here, the mail delivery time is calculated from the reception time and the transmission time described in the mail. After completing the calculation of the delivery time, the mail communication measuring unit 62 requests the environment measuring unit 65 for the environment measuring process S12, and the environment measuring unit 65 performs the environment measuring process S12 described in FIG. When the environmental measurement process S12 is completed, the environmental measurement unit 65 notifies the mail communication measurement unit 62 of the environmental measurement value.

  Returning to FIG. 15, the mail communication measurement unit 62 that has finished the SMS reception measurement process S41 cancels the “SMS reception measurement state” and notifies the measurement management unit 61 of the completion of the SMS reception measurement. The measurement management unit 61 notified of the completion of the SMS reception measurement requests the measurement report processing unit 64 to process the measurement report. The measurement report processing unit 64 performs the above-described measurement report processing S6 of FIG. Here, as shown in FIG. 17, the created measurement report includes the information of the mobile phone 10 on the receiving side and the calculated distribution in addition to the content of the measurement report when the mail transmission in FIG. 14 fails. Includes time. When the measurement report process S6 ends, the measurement management unit 61 is notified of the completion of the measurement report process.

  Subsequently, when an MMS mail is received in the “MMS reception measurement state”, the MMS reception measurement process S42 is performed. In FIG. 18, the mail communication unit 74 of the quality management server 52 creates an e-mail for measurement and transmits it to the mobile phone 10. The transmitted e-mail is delivered to the MMS server 47 via the Internet network 50 and converted into MMS mail in the MMS server 47. The converted MMS mail is delivered from the mobile communication network 40 to the mail communication measurement unit 62 via the transmission / reception unit 22 of the mobile phone 10. The delivered MMS mail is obtained by the mail communication measurement unit 62 in the same manner as in the SMS reception measurement process S41 of FIG. 16 to confirm whether it is a command and a measurement mail. However, when it is not a command but a measurement mail, a delivery time calculation process is performed. After completing the calculation of the delivery time, the mail communication measuring unit 62 requests the environment measuring unit 65 for the environment measuring process S12, and the environment measuring unit 65 performs the environment measuring process S12 described in FIG. When the environmental measurement process S12 is completed, the environmental measurement unit 65 notifies the mail communication measurement unit 62 of the environmental measurement value.

  Returning to FIG. 15, the mail communication measurement unit 62 that has finished the MMS reception measurement process S 42 cancels the “MMS reception measurement state” and notifies the measurement management unit 61 of the completion of the MMS reception measurement. Thereafter, as in the case of SMS reception, a request for measurement report processing by the measurement management unit 61, a measurement report processing S6 by the measurement report processing unit 64, and a notification of completion of the measurement report processing are performed.

  Next, the HTTP communication measurement report process S5 will be described. In the HTTP communication measurement report processing S5, as shown in FIG. 19, first, the measurement management unit 61 requests the HTTP communication measurement unit 63 for the HTTP communication measurement processing S51. The HTTP communication measurement unit 63 that has received the request for the HTTP communication measurement process S51 performs the HTTP communication measurement process S51. As shown in FIG. 20, the HTTP communication measurement process S51 first checks whether or not the time synchronization process has been completed, as in the SMS / MMS transmission measurement process S31. If the time synchronization process has not yet been performed, the mail communication measuring unit 62 requests the timer unit 34 for the time synchronization process, and the timer unit 34 executes the time synchronization process S11. On the other hand, if the time synchronization process has already been performed, the process proceeds to the next process without requesting the time synchronization process.

  In this case, since the time synchronization process S11 is performed when the SMS / MMS transmission measurement process S31 is executed, it is determined that the time synchronization process is completed, and the process proceeds to the next process. Subsequently, as in the SMS / MMS transmission measurement process S31, the HTTP communication measurement unit 63 requests the environment measurement process S12, the environment measurement unit 65 performs the environment measurement process S12, and the notification of the measured environment measurement value is sent to the HTTP communication. This is performed on the measurement unit 63.

  The HTTP communication measurement unit 63 that has received the notification of the environmental measurement value determines whether or not measurement is possible. Here, the requirements for enabling measurement are that the mobile phone 10 is not in communication and that the acquired electric field strength value is equal to or greater than a predetermined value, as in the SMS / MMS transmission measurement process S31. is there. If it is not determined that measurement is possible, the HTTP communication measurement process S51 ends.

  On the other hand, when it is determined that measurement is possible, the HTTP communication measurement unit 63 acquires the current time from the timer unit 34 and sets it as the communication start time. Subsequently, the HTTP communication measurement unit 63 selects an address at random from preset connection destination addresses of HTTP communication. The HTTP communication measurement unit 63 then requests content data from the Internet content server 51 that is the access destination of the selected address via the transmission / reception unit 22 and the gateway server 45 of the mobile phone 10. The Internet content server 51 traces the requested content data in reverse on the same route and notifies the mobile phone 10. The HTTP communication measuring unit 63 of the mobile phone 10 receives the notified content data. The HTTP communication measurement unit 63 that has completed the acquisition of the content data acquires the current time from the timer unit 34, sets the communication end time, and calculates the communication time from the difference between the communication end time and the communication start time.

  Returning to FIG. 19, the HTTP communication measurement unit 63 that has calculated the communication time notifies the measurement management unit 61 of completion of the HTTP communication measurement process S51. Upon receiving the notification of completion of the HTTP communication measurement process, the measurement management unit 61 requests the measurement report processing unit 64 to process the measurement report. The measurement report processing unit 64 requested to process the measurement report performs the measurement report processing S6 in the same manner as after the SMS reception measurement processing. Here, as shown in FIG. 21, the measurement data included in the created measurement report includes information of the mobile phone 10 such as a set telephone number, information acquired by the environment measurement process S12, access destination URL, communication The start time, the end time, the communication time calculated from these times, the acquired data amount, and the communication speed calculated from the communication time and the acquired data amount. When the measurement report process S6 ends, the measurement management unit 61 is notified of the completion of the measurement report process. Thereafter, similarly, the measurement management unit 61 executes the mail transmission measurement report process S3, the mail reception measurement report process S4, and the HTTP communication measurement report process S5 every time the measurement time elapses.

  As described above, in the present embodiment, in the application 31 that measures the communication quality installed in the mobile phone 10, first, the e-mail transmission measurement report process S <b> 3 is performed as the timer set time elapses. In the mail transmission measurement report process S3, the current position, electric field strength, etc., which are the environment of the mobile phone 10, are measured. Next, SMS and MMS mails are sent with information such as the address of the mobile phone 10 and environmental measurement values such as electric field strength as the body of the mail. If the email transmission is successful, the email transmission measurement report processing S3 ends. If the email transmission fails, a measurement report is created that contains the content of the body of the email that was attempted to be sent. When two or more created measurement reports are accumulated, it is transmitted to the quality management server 52. The quality management server 52 that has received the notification of the measurement report performs statistical processing together with the content of the previously reported measurement report, and notifies the administrator if there is an abnormality. In addition, when the mail transmission destination is the quality management server 52, the quality management server 52 that has received the mail performs statistical processing as in the case of the measurement report. Notice.

  Next, the application 31 performs mail reception measurement report processing S4 when the timer set time elapses. In the mail reception measurement report processing S4, the application 31 receives an email for measurement which is an SMS or MMS mail and includes the measured value of the environment of the transmitted mobile phone as a body, calculates its delivery time, and receives it. Measure the environment. Subsequently, a measurement report is created with the content of the text of the received mail, the delivery time, the reception environment, etc. as the content of the measurement report. When two or more created measurement reports are accumulated, it is transmitted to the quality management server 52. The quality management server 52 that has received the notification of the measurement report performs statistical processing together with the content of the previously reported measurement report, and notifies the administrator if there is an abnormality.

  Finally, the application 31 performs HTTP communication measurement report processing S5 as the timer set time elapses. In the HTTP communication measurement report processing S5, after measuring the environment of the mobile phone 10, the address on the Internet is accessed, communication using the HTTP protocol is performed, and the response time is measured. Subsequently, a measurement report is created with the accessed address, response time, measurement environment, etc. as the content of the measurement report. When two or more created measurement reports are accumulated, it is transmitted to the quality management server 52. The quality management server 52 that has received the notification of the measurement report performs statistical processing together with the content of the previously reported measurement report, and notifies the administrator if there is an abnormality.

  Therefore, according to the present embodiment, the communication quality provided to the user of the mobile communication terminal device can be measured, and the measured data can be easily collected.
