In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 schematically shows an example of a communication environment of the communication management system 100. The communication management system 100 manages communication between a plurality of communication terminals. Here, an example in which the communication management system 100 manages communication between the mobile phone 30 and the server 60 via the relay station 20, the core network 10, and the Internet 50 will be described.

The relay station 20 may be a radio base station of a mobile communication system. For example, the relay station 20 is any one of a radio base station of a third generation mobile communication system, an LTE (Long Term Evolution) radio base station, and a radio base station of a fourth generation or later mobile communication system.

  The mobile phone 30 and the server 60 are examples of communication terminals. The server 60 is various servers connected to the Internet 50 such as a Web server. Other examples of the communication terminal include a tablet terminal, a PDA (Personal Data Assistance), a PC (Personal Computer), and a wearable computer.

  The communication management system 100 includes a communication management device 200 and a quality evaluation device 300. The communication management system may further include a plurality of relay stations 20. The communication management device 200 and the quality evaluation device 300 belong to the core network 10. The core network 10 may be a network managed by a telecommunications carrier that provides a communication service to the mobile phone 30. Note that the quality evaluation apparatus 300 may not belong to the core network. For example, the quality evaluation device 300 may be connected to the communication management device 200 via the Internet 50.

  The communication management apparatus 200 is an apparatus that relays and analyzes communications of a plurality of communication terminals. The communication management device 200 may be a device that analyzes a packet passing through the communication management device 200. For example, the communication management apparatus 200 is an apparatus having a DPI (Deep Packet Inspection) function. The communication management apparatus 200 is an apparatus that analyzes, for example, QoE (Quality of Experience) of communication of a plurality of communication terminals.

  The communication management apparatus 200 according to the present embodiment measures the response time of communication via the relay station 20 by the communication terminal for each of the plurality of relay stations 20. The quality evaluation apparatus 300 according to the present embodiment evaluates the plurality of relay stations 20 based on the response time measured by the communication management apparatus 200.

  FIG. 2 schematically shows an example of response time measurement processing by the communication management apparatus 200. The communication management apparatus 200 measures response time when relaying data transmitted and received in order to establish a communication connection between one communication terminal and another communication terminal. FIG. 2 illustrates a case where the mobile phone 30 and the server 60 establish a communication connection by a three-way handshake.

  In step (step may be abbreviated as S) 202, the mobile phone 30 transmits a SYN packet addressed to the server 60 to the relay station 20. In S <b> 204, the relay station 20 transmits the SYN packet received from the mobile phone 30 to the communication management apparatus 200. In step S206, the communication management apparatus 200 transmits the SYN packet received from the relay station 20 to the server 60.

  In S208, the server 60 transmits a SYN / ACK packet corresponding to the SYN packet received in S206 to the communication management apparatus 200. In S210, the communication management apparatus 200 transmits the SYN / ACK packet received from the server 60 to the relay station 20. In S <b> 212, the relay station 20 transmits the SYN / ACK packet received from the communication management device 200 to the mobile phone 30.

  In S214, the mobile phone 30 transmits an ACK packet for the SYN / ACK packet received in S212 to the relay station 20. In S <b> 216, the relay station 20 transmits the ACK packet received from the mobile phone 30 to the communication management apparatus 200. In S218, the communication management apparatus 200 transmits the ACK packet received from the relay station 20 to the server 60.

  The communication management device 200 transmits the SYN packet to the server 60 in S206 as the response time of communication through the relay station 20 by the mobile phone 30, and the time until the ACK packet is received from the relay station 20 in S216. May be measured. Accordingly, it is possible to measure the response time that is the sum of the response time of the communication path between the mobile phone 30 and the communication management apparatus 200 and the response time of the communication path between the communication management apparatus 200 and the server 60. In a pseudo manner, the response time of the communication path from the mobile phone 30 to the server 60 can be measured.

  As a method for measuring the response time between the mobile phone 30 and the server 60, a method in which the mobile phone 30 performs Ping on the server 60 is known. However, in order to evaluate a plurality of relay stations 20, it is necessary to ping the mobile phone 30 located in each relay station 20, so that the number of relay stations 20 such as Wi-Fi access points is arranged. Is enormous, and it is difficult to place the evaluation mobile phone 30 in all the relay stations 20. It is also difficult to cause a general user's mobile phone 30 located in each of the plurality of relay stations 20 to ping. On the other hand, according to the communication management apparatus 200 according to the present embodiment, the response time is measured along with the relay of data transmitted and received in order to establish a communication connection between one communication terminal and another communication terminal. The response time can be measured for each of the plurality of relay stations 20.

  The communication management apparatus 200 transmits a SYN / ACK packet to the relay station 20 in S210 as a response time of communication through the relay station 20 by the mobile phone 30, and receives an ACK packet from the relay station 20 in S216. The time until may be measured. The communication path between the mobile phone 30 and the communication management apparatus 200 is composed of a wireless communication path between the mobile telephone 30 and the relay station 20 and a wired communication path between the relay station 20 and the communication management apparatus 200. Is done. The communication path between the communication management device 200 and the server 60 is mostly the Internet 50. As the response time, by measuring the time from the transmission of the SYN / ACK packet to the relay station 20 in S210 to the reception of the ACK packet from the relay station 20 in S216, the degree of relevance with the relay station 20 is increased. The response time of a high communication path can be measured.

  The quality evaluation apparatus 300 displays the response time measured by the communication management apparatus 200 from the transmission of the SYN packet to the server 60 in S206 to the reception of the ACK packet from the relay station 20 in S216 from the communication management apparatus 200. You may receive it. And the quality evaluation apparatus 300 may evaluate the some relay station 20 based on the said response time.

  The quality evaluation apparatus 300 determines the response time measured by the communication management apparatus 200 from the transmission of the SYN / ACK packet to the relay station 20 in S210 to the reception of the ACK packet from the relay station 20 in S216. You may receive from the apparatus 200. FIG. And the quality evaluation apparatus 300 may evaluate the some relay station 20 based on the said response time.

  Here, when a general existing product is used as the communication management apparatus 200, the response time from when the SYN packet is transmitted to the server 60 at S206 until the ACK packet is received from the relay station 20 at S216, Although it is possible to obtain the response time from the transmission of the SYN packet to the server 60 in S206 to the reception of the SYN / ACK packet from the server 60 in S208, the SYN / ACK packet is transmitted to the relay station 20 in S210. It is not possible to acquire the response time from the transmission to the reception of the ACK packet from the relay station 20 in S216. Therefore, the quality evaluation apparatus 300 transmits the SYN packet to the server 60 in S206 from the response time until the ACK packet is received from the relay station 20 in S216 after the SYN packet is transmitted to the server 60 in S206. Then, by subtracting the response time until the SYN / ACK packet is received from the server 60 in S208, the SYN / ACK packet is transmitted to the relay station 20 in S210, and then the ACK packet is transmitted from the relay station 20 in S216. The response time until receiving the signal may be derived.

  The quality evaluation apparatus 300 calculates the average value and standard deviation of the response time for each of the plurality of relay stations 20 in order to evaluate the plurality of relay stations 20. Then, the quality evaluation device 300 classifies the plurality of relay stations 20 based on the average value and the standard deviation.

  The plurality of relay stations 20 can be classified based only on the average value of the response times. In this case, however, the response time is generally short when the majority of response times are short but the number of response times is extremely long. Indistinguishable from long case. The relay station 20 with a long overall response time should be improved more preferentially than the relay station 20 with a short majority of response times but a small number of extremely long response times. The latter cannot be specified by classification based on. On the other hand, since the quality evaluation apparatus 300 according to the present embodiment classifies the plurality of relay stations 20 based on the average value and standard deviation of the response time, the former and the latter can be distinguished, and preferentially The relay station 20 to be improved can be identified.

  The quality evaluation apparatus 300 may generate graph data in which data indicating a plurality of relay stations 20 is arranged on a graph with the average value of response times and the standard deviation as axes. Further, the quality evaluation apparatus 300 classifies the plurality of relay stations 20 into a plurality of categories for each predetermined period based on the average value and standard deviation of response times for each predetermined period, and is determined in advance. Graph data indicating the ratio of each of a plurality of categories for each period in time series may be generated.

  FIG. 3 schematically shows an example of the graph data 400 generated by the quality evaluation apparatus 300. The horizontal axis of the graph data 400 indicates the average response time. The vertical axis of the graph data 400 indicates the standard deviation of response time. Each of the plurality of plots 401 represents each of the plurality of relay stations 20.

  The quality evaluation apparatus 300 may display the generated graph data 400 on a display (not shown) included in the quality evaluation apparatus 300. The quality evaluation apparatus 300 may transmit the generated graph data 400 to another apparatus and display it on the other apparatus. Thereby, a viewer can specify the relay station 20 which should improve preferentially among several relay stations 20. FIG.

  FIG. 4 schematically shows an example of the category of the relay station 20. FIG. 4 exemplifies a case where classification is made into four categories depending on whether the average value of response times is 100 ms or less and whether the standard deviation of response times is 600 ms or less.

  The category A402 is a category of the relay station 20 in which the average response time is smaller than 100 ms and the standard deviation of the response time is smaller than 600 ms. The category B404 is a category of the relay station 20 whose average response time is smaller than 100 ms and whose response time standard deviation is 600 ms or more. The category C406 is a category of the relay station 20 whose average response time is 100 ms or more and whose standard deviation of response time is smaller than 600 ms. The category D408 is a category of the relay station 20 whose average response time is 100 ms or more and whose standard deviation of response time is 600 ms or more.

  FIG. 5 schematically shows an example of the graph data 500 generated by the quality evaluation apparatus 300. Graph data 500 is a category for each day when a plurality of relay stations 20 are classified into category A 402, category B 404, category C 406, and category D 408 for each day based on the average value and standard deviation of response times for each day. The ratio for each is shown.

  The quality evaluation apparatus 300 may display the generated graph data 500 on a display (not shown) provided in the quality evaluation apparatus 300. Further, the quality evaluation apparatus 300 may transmit the generated graph data 500 to another apparatus and display it on the other apparatus. Thereby, the viewer can specify the ratio of the relay stations 20 to be improved among the plurality of relay stations 20. Thereby, for example, it is possible to easily set a specific target such as setting the ratio of category A402 to 95% or more.
