[Description of quality state detection method]
FIG.3 and FIG.4 is a schematic diagram of the quality state detection method which the management apparatus 300 which concerns on this Embodiment performs. FIG. 3 schematically shows the point P at which the communication terminal 200 has measured the quality information on a map. The acquisition unit 311 of the management device 300 acquires quality information indicating communication quality and position information indicating the position at which the communication quality is measured, from the communication terminal 200 used by the user via the communication unit 320 (a) . The acquisition unit 311 stores the acquired quality information and position information in the storage unit 330 (b).

  Specifically, the acquisition unit 311 is a communication terminal 200 at the time of measuring the communication quality measured using the quality information indicating the communication quality measured by the communication terminal 200 with the base station 10 and the positioning signal from the GPS satellite. Get the position (coordinates) of. Although RSSI or SNR is used as the communication quality in the present embodiment, other indicators capable of indicating high or low communication quality or poor may be used. Also, the communication quality may indicate that the communication has been terminated normally or has been abnormally terminated (disconnected).

  The communication terminal 200 may measure communication quality in either voice communication or data communication, or may measure communication quality by limiting to communication using a specific software. The communication terminal 200 may measure the communication quality in each communication, or may measure the communication quality in the communication when a predetermined time has elapsed since the previous measurement.

  Moreover, the measurement of the position by the communication terminal 200 is not limited to a specific method. For example, the communication terminal 200 may estimate the position of the communication terminal 200 at the time of communication quality measurement based on the position of the cell of the communicable base station 10. The communication terminal 200 measures the position at the time of communication quality measurement, at the start, at the end, or at the end of the communication at which the communication quality was measured. Communication terminal 200 transmits quality information and position information to management device 300 via communication unit 210 included in communication terminal 200.

  The communication terminal 200 transmits a message (for example, the messages M1 and M2 in FIG. 3) input by the user to the message server 100 that provides a message transmission / reception service via the communication unit 210 of the communication terminal 200. When the message server 100 acquires the message transmitted from the communication terminal 200 (c), the message server 100 stores the message in a storage unit (not shown) included in the message server 100 (d).

  FIG. 4 schematically shows the messages M1 and M2 acquired by the message server 100 on the display screen. The acquisition unit 311 searches the message server 100 for a message including a predetermined keyword via the communication unit 320 (e). The acquiring unit 311 includes, for example, a keyword (for example, communication and radio waves) indicating that the content is related to communication, and a keyword (for example, bad and broken etc.) indicating that the content is negative for communication quality. Search for a message

  The acquiring unit 311 may determine whether or not a keyword (for example, an accident, a weather, an event, or the like) related to a factor affecting the communication quality is included in the message in addition to the above-described keyword. By doing this, the acquiring unit 311 can more easily determine whether the communication carrier needs to take measures to improve the communication quality.

  The acquisition unit 311 acquires a message including a predetermined keyword related to communication quality from the message server 100 based on the search result (f). At this time, in addition to the message, the acquisition unit 311 acquires identification information that identifies the user who has posted the message, and the posting time at which the message was posted. The acquisition unit 311 inputs the acquired identification information to the identification unit 312 described later.

  The identifying unit 312 identifies the user who has posted the message acquired by the acquiring unit 311 (g). Specifically, the identifying unit 312 identifies the user using the identification information. The identification information is information used by the message server 100 to manage information on the user posting the message, and is, for example, a user ID. The management device 300 stores the identification information managed by the message server 100 in association with the information on the user who uses the communication terminal 200. The identifying unit 312 acquires, from the storage unit 330, information related to the user associated with the user ID acquired by the acquiring unit 311.

  The information used by the identifying unit 312 to identify the user is not limited to the user ID. For example, the identifying unit 312 may identify the user who has posted the message based on the IP address assigned to the communication terminal 200 using the communication line by the communication carrier. Specifically, when the acquiring unit 311 acquires from the message server 100 the IP address of the communication terminal 200 that has transmitted the message, the identifying unit 312 stores information on the user associated with the acquired IP address. It may be acquired from 330. By doing this, the identifying unit 312 can identify the user who posted the message even when the communication carrier does not know the user ID of the message server 100. The identifying unit 312 inputs information on the identified user to the acquiring unit 311.

  The acquisition unit 311 acquires, from the storage unit 330, the quality information acquired from the communication terminal 200 corresponding to the user based on the information on the identified user. Specifically, when the acquisition unit 311 specifies the user who has posted the message, the communication quality measured by the communication terminal 200 corresponding to the user within a predetermined time including the post time when the message was posted Is acquired from the storage unit 330. The predetermined time is, for example, 10 minutes from the time 5 minutes before the posting time to the time 5 minutes after the posting time. A predetermined time is preset in the management device 300.

  By the way, when the acquiring unit 311 acquires from the storage unit 330 the quality information acquired from the communication terminal 200 corresponding to the specified user, there is no quality information indicating the communication quality measured in the time close to the posting time. There is. Therefore, when the identifying unit 312 identifies the user who has posted the message, the acquiring unit 311 indicates the quality of communication quality measured by the communication terminal 200 corresponding to the user within a predetermined time including the posting time at which the message was posted. When there is no information, the communication terminal 200 may be requested to transmit quality information. The acquiring unit 311 acquires the quality information indicating the communication quality measured at the time closest to the posting time, transmitted from the communication terminal 200 that has received the transmission request. By doing this, the acquisition unit 311 can more accurately understand the communication quality for the posted message.

  The quality determination unit 313 determines whether the communication quality at the position indicated by the position information is normal based on the quality information (h). Specifically, based on the quality information, the quality determination unit 313 determines whether the communication quality in a predetermined range from the position indicated by the position information is normal. For example, when the value of RSSI or SNR as the communication quality indicated by the quality information exceeds a predetermined value, the quality determining unit 313 indicates that the communication quality in a predetermined range from the position indicated by the position information corresponding to the quality information is normal. It is determined that On the other hand, when the value of the RSSI or SNR is equal to or less than a predetermined value, the quality determination unit 313 determines that the communication quality in a predetermined range from the position indicated by the position information corresponding to the quality information is abnormal.

  Here, the predetermined range is a fixed range centered on the position indicated by the position information. The quality determination unit 313 may change the predetermined range according to the type of the keyword related to the factor that has influenced the communication quality included in the message acquired by the acquisition unit 311. For example, when an event such as a concert or a fireworks display is held, the quality determination unit 313 determines whether the communication quality is normal, with the venue indicated by the position information as a predetermined range.

  The quality determination unit 313 may determine whether the communication quality is normal based on the number of messages acquired by the acquisition unit 311. Specifically, based on the number of messages posted by the user corresponding to communication terminal 200 that has measured communication quality at a position included in one predetermined range, quality determination unit 313 determines the number in the one predetermined range. It may be determined whether the communication quality is normal. For example, as shown in FIG. 3, the quality judging unit 313 manages the number of messages posted by the user corresponding to the communication terminal 200 whose communication quality has been measured at the position included in the predetermined range A1. When the number is less than or equal to the predetermined number set in the device 300, it is determined that the communication quality in the predetermined range A1 is normal. On the other hand, when there are a large number of messages posted by the user corresponding to communication terminal 200 whose communication quality has been measured at a position included in predetermined range A2, quality determination unit 313 determines the predetermined range when the number exceeds the predetermined number. It is determined that the communication quality in A2 is abnormal. The threshold of the number of messages is set in advance in the management apparatus 300.

  When the quality determination unit 313 determines that the communication quality is abnormal, the weighting unit 314 notifies the user specified by the specification unit 312 based on the type of the predetermined keyword included in the message acquired by the acquisition unit 311. The position indicated by the position information corresponding to the quality information acquired from the corresponding communication terminal 200 is weighted (i). The type of the predetermined keyword is, for example, a keyword indicating that communication can not be performed, and a keyword indicating that communication is delayed. In the management device 300, priorities of predetermined keyword types are set in advance.

  Here, it is assumed that the keyword indicating that the communication can not be performed has a higher priority than the keyword indicating that the communication is in a delayed state. In addition, as shown in FIG. 3, the message M1 associated with the point P1 in which the communication quality is determined to be abnormal is “radio wave is bad” and the point P2 in which the communication quality is determined to be abnormal. It is assumed that there is a message "communication is disconnected" which is the associated message M2.

  In this case, the weighting unit 314 indicates a low priority keyword (that is, communication is delayed) with respect to the point P2 corresponding to the message M2 including a high priority keyword (that is, a keyword indicating a state in which communication can not be performed). Weighting with higher importance than the point P1 corresponding to the message M1 including the On the other hand, the weighting unit 314 weights the point P1 corresponding to the message M1 including the low priority keyword lower in importance than the point P2 corresponding to the message M2 including the high priority keyword. By doing this, when there are a plurality of points where there is an abnormality in the communication quality, the weighting unit 314 can cause the communication carrier to recognize points that need to be prioritized.

  The output unit 315 outputs the quality state detected by the quality judgment unit 313 judging that the communication quality is abnormal. Specifically, when the quality determining unit 313 determines that the communication quality at the position indicated by the position information is abnormal, the output unit 315 determines the message acquired by the acquiring unit 311 and the user identified by the identifying unit 312. The quality information acquired from the communication terminal 200 corresponding to B, the position information corresponding to the quality information, and the information on the position (point) weighted by the weighting unit 314 are associated and output (j). By doing this, in response to the management apparatus 300 acquiring a message including a predetermined keyword from the message server 100, the quality based on the communication quality measured by the communication terminal 200 corresponding to the user who has posted the message. The state can be detected.

  The output unit 315 may output information on a map as shown in FIG. 3 or a message including a predetermined keyword, quality information and information indicating a point (for example, latitude and longitude, or an address). It may be output as a message. For example, when outputting information on a map as shown in FIG. 3, the output unit 315 displays information on each point P according to the degree of importance as information on the points weighted by the weighting unit 314 (for example, Output in different colors, shapes, patterns, etc. depending on the importance. The output unit 315 may display the output information on a display (not shown) included in the management apparatus 300, or may display the output information on a management terminal managed by the provider via the communication unit 320.

  The output unit 315 may output the message and the quality information on condition that an output for a predetermined range from the position indicated by the position information corresponding to the quality information has passed a predetermined time since the last output. The predetermined time is the minimum time (for example, 10 minutes from the immediately preceding output) in which it is assumed that the factor leading to the determination that the communication quality is abnormal continues. A predetermined time is preset in the management device 300. By doing this, the output unit 315 can suppress repeated output of messages having the same content at the same place.

[Operation of Communication System S]
FIG. 5 is a sequence diagram showing the flow of the operation of the communication system S according to the present embodiment. Communication terminal 200 transmits quality information indicating communication quality and position information indicating a position at which communication quality is measured, to management device 300 via communication unit 210 of communication terminal 200. The timing at which the communication terminal 200 transmits the quality information and the position information to the management apparatus 300 may be when the communication quality is measured, or may be at a predetermined interval (for example, once a day). The acquisition unit 311 acquires the quality information indicating the communication quality transmitted from the communication terminal 200 and the position information indicating the position at which the communication quality is measured, and stores the acquired information in the storage unit 330.

  The acquisition unit 311 searches the message server 100 for a message including a predetermined keyword (S11). The timing at which the acquisition unit 311 searches for a message may be a predetermined interval (for example, once in one hour), or the predetermined interval may be changed according to a time zone (for example, the predetermined interval may be shortened in the daytime, In the nighttime, the predetermined interval may be increased. The acquisition unit 311 acquires a message including a predetermined keyword related to communication quality from the message server 100 based on the search result. At this time, the acquisition unit 311 acquires identification information and a posting time.

  The identifying unit 312 identifies the user who has posted the message acquired by the acquiring unit 311 using identification information (S12). If the specifying unit 312 can not specify the user using the identification information (NO in S13), the processing ends. On the other hand, when the identifying unit 312 can identify the user using the identification information (in the case of YES in S13), the acquiring unit 311 determines the communication terminal 200 corresponding to the user based on the information on the identified user. The quality information acquired from is acquired from the storage unit 330 (S14).

  The quality determination unit 313 determines whether the communication quality at the position indicated by the position information is normal based on the quality information acquired by the acquisition unit 311 (S15). If the quality determination unit 313 determines that the communication quality is normal (YES in S16), the process ends.

  On the other hand, when it is determined that the communication quality is abnormal (in the case of NO in S16), the weighting unit 314 determines the communication corresponding to the identified user based on the type of the predetermined keyword included in the acquired message. Weighting is performed on the position indicated by the position information corresponding to the quality information acquired from the terminal 200 (S17).

  Then, the output unit 315 determines, as the quality state, the message acquired by the acquisition unit 311, the quality information acquired from the communication terminal 200 corresponding to the user specified by the identification unit 312, and the position information corresponding to the quality information. The weighting unit 314 associates information with the point on which the weighting is performed and outputs the information (S18).

[Effect of this embodiment]
As described above, the management device 300 identifies the user who has posted the message acquired by searching the message server 100 based on the predetermined keyword, and the quality acquired from the communication terminal 200 corresponding to the user It is determined whether the communication quality indicated by the information is normal. Then, when the management device 300 determines that the communication quality is abnormal, a message including a predetermined keyword acquired from the message server 100, and quality information acquired from the communication terminal 200 corresponding to the user who has posted the message. And outputting position information indicating a position at which the communication quality indicated by the quality information is measured. According to such a configuration, in response to acquiring a message regarding communication quality from the message server 100, the management device 300 detects a position where there is an abnormality in the communication quality, and outputs information for verifying the communication quality. can do. As a result, the communication carrier can associate and verify the message posted by the user to the message server 100 and the communication quality actually measured.

  For example, when the user posts a message such as “bad radio wave” by specifying the user who has posted the message including the predetermined keyword, the communication company can communicate with the user corresponding to the user. The state of communication quality can be objectively grasped based on the quality information acquired from the terminal 200. Furthermore, when the management apparatus 300 acquires a message from the message server 100, it is not necessary to install an application on the communication terminal 200 side, so that the operation delay of the communication terminal 200 and the increase in battery consumption can be prevented. .
