Description

  The present invention relates to a throughput measurement technique for measuring the throughput of a data communication terminal.

  With the spread of data communication services using cellular phones, communication environment maintenance work based on the throughput measurement of cellular phones is being performed. For example, it is possible to evaluate the communication environment, functionality, etc. by measuring the throughput of each mobile phone between different mobile phone operators or between different mobile phones and quantifying and comparing the measurement results it can.

  FIG. 9 shows an example of a conventional throughput measurement system. The measurement target mobile phones k1 to k3 are connected to the PCs 1 to 3 that execute the throughput measurement process, respectively, and can be connected to the measurement servers s1 to s3 via the Internet 1, respectively. Note that the mobile phones k1 to k3 are connected to the Internet via a RAS server (not shown) installed in each business operator. Each of the PCs 1 to 3 measures the throughput value of the communication environment in each of the mobile phones k1 to k3 by exchanging data with the measurement servers s1 to s3.

  A radio wave quality measuring apparatus that measures radio wave quality for a plurality of mobile phones using a single measuring apparatus is known (for example, see Patent Document 1).

  However, in the method of measuring the throughput value shown in FIG. 9, in principle, one PC is required to measure the throughput of one mobile phone. This is because there is only one IP address of the default gateway that can be connected to the Internet 1 on the PC side that performs the throughput measurement. In other words, it is because there cannot theoretically be two gateway IP addresses designated as defaults.

  On the other hand, it is possible to perform throughput measurement for each mobile phone by connecting a plurality of mobile phones to one PC. In this case, since the IP address of the most recently connected mobile phone is used as the default gateway on the PC, it is difficult to measure the throughput of multiple mobile phones at the same time, and each mobile phone is connected to the Internet. However, there was no choice but to perform throughput measurement for each connection.

The throughput measurement program 2091 performs various processes according to the throughput measurement system of the present invention in response to an operation instruction from the operator. This program is installed by reading the program recorded on the CD-ROM 212 via the CD-ROM drive 211. The installation may be performed using a program downloaded from a network such as the Internet. In the memory 205, a route table 2051 and a correspondence table 2053 are recorded. Here, the route table 2051 indicates a gateway IP address used to connect to a predetermined computer, and the correspondence table 2053 indicates a relationship between the mobile phone and the measurement server IP address.

  The connection request unit a1, the path information acquisition unit a2, the path table recording unit a3, and the throughput measurement unit a4 that constitute the measurement PCa are realized by functions of the throughput measurement program 2091.

The response means b constituting the measurement servers b1 to b3 is realized by each function by the response program 3091.

1-2-3. Mobile phone (data communication terminal)
The mobile phone has only to have a communication port for connecting to the USB port of the measurement PC and can be connected to the Internet 1 by dial-up connection to a predetermined RAS server by wireless communication.

1-3. Processing Details Processing details in this embodiment will be described with reference to FIGS. In the present embodiment, an example will be described in which a measurement PC to which a plurality of mobile phones are connected measures the throughput of each mobile phone by accessing a measurement server on the Internet via each mobile phone.

1-3-1. Route Table Creation Processing FIG. 4 is a flowchart for creating a route table 2051 (routing table) in the throughput measurement system of this embodiment. When the operator performs a program activation operation using the keyboard / mouse 207 of the measurement PCa, the CPU 203 of the measurement PCa activates the throughput measurement program 2091 recorded in the hard disk 209 (step S401).

  The CPU 203 searches the USB port 215 and recognizes the mobile phone connected to the USB port (step S403). For example, the mobile phone c1 is recognized by searching the USB port u1.

  When the CPU 203 recognizes that the mobile phone is connected (step S405), it makes a connection request to the Internet to the mobile phone (step S407). For example, the CPU 203 sends an AT command to the mobile phone c1 to make a connection request to the Internet.

  In response to the connection request, the mobile phone starts connection to the RAS server having a gateway function for connecting to the Internet (step S421). For example, the mobile phone c1 connects to the RAS server based on connection information set in advance.

  When the connection to the RAS server is completed, the mobile phone transmits a connection completion code to the measurement PC (step S423). For example, when an AT command is used, a result code indicating a successful connection is transmitted.

  Upon receipt of the transmission, the CPU 203 of the measurement PCa acquires route information (step S409). For example, as shown in FIG. 6A, in the case of a Windows (trademark) OS, it is possible to acquire route information related to the mobile phone c1 connected to the Internet by the “ipconfig” command. In FIG. 6, the identification name of the mobile phone c1 is “KEITAI_A”, the global IP address and the default gateway are “219.108.47.128”, and the subnet mask is “255.255.255.255”. Has been.

  When the route information is acquired, the CPU 203 starts connection to a predetermined measurement server (step S411). For example, when connecting to the measurement server b1, the CPU 203 accesses the preset IP address “12.34.56.101” via the mobile phone c1.

  The CPU 203 records the relationship between the mobile phone connected in the above and the measurement server connected via the Internet in the correspondence table 2053 (step S413). For example, as shown in FIG. 6B, the mobile phone “KEITAI_A” and the measurement server IP address “12.34.56.101” are recorded.

  The CPU 203 records the route information regarding the measurement server connected via the Internet in the route table 2051 (step S415). For example, based on the route information shown in FIG. 6A, using the “route” command shown in FIG. 7B, the measurement server IP address “12.34.56.101” is stored in the route table 2051 of the measurement PC. ”Is recorded as the gateway address“ 219.108.47.128 ”. The gateway address “219.108.47.128” is obtained from the global IP address of the mobile phone “KEITAI_A” or the default gateway “219.108.47.128” shown in FIG.

  FIG. 7A shows an example of the route table 2051. The route information related to the record 701 is added by the “route” command. The route information record 701 includes “Network Destination” 71 indicating connection destination information, “Netmask” 73 indicating netmask information, “Gateway” 75 serving as a transmission destination gateway when connecting to the connection destination, and the like. The Accordingly, when connecting to the measurement server b1 (IP address “12.34.56.101”), the mobile phone c1 can be used based on the gateway IP address “219.108.47.128”.

  When the recording of the route table 2051 is completed, the CPU 203 determines whether or not the mobile phone has been searched for all the USB ports. If there is an unsearched USB port (NO in step S417), the process returns to step S403. The same processing as described above is performed for the mobile phone. For example, the processes of steps S403 to S415 are performed for the mobile phone c2 and the measurement server b2 (IP address “12.34.56.102”), and records are added to the correspondence table 2053 and the route table 2051, respectively.

  When the CPU 203 determines that the mobile phone has been searched for all the USB ports (u1 to u3), the CPU 203 ends the processing (step S417, YES).

1-3-2. Throughput Measurement Processing FIGS. 5 and 5a are flowcharts in the case where the throughput measurement in the plurality of mobile phones is simultaneously performed using the route table 2051 (routing table) in the throughput measurement system of the present embodiment. FIG. 8 shows an example of a throughput measurement screen 800 displayed on the display 201 of the measurement PCa when the throughput measurement program 2091 is started.

  In FIG. 5, when the operator presses the measurement start button 801 with the keyboard / mouse 207 of the measurement PCa, the CPU 203 of the measurement PCa reads all the mobile phones with reference to the correspondence table 2053 (steps S551 to S553). For example, in the correspondence table shown in FIG. 6B, all the identification names “KEITAI_A”, “KEITAI_B”, and “KEITAI_C”, which are identification names of mobile phones, are read.

  The CPU 203 simultaneously executes the throughput measurement process shown in FIG. 5a for each of the read mobile phones (steps S555 to S559). In FIG. 5a, the CPU 203 obtains from the correspondence table 2053 the IP address of the measurement server recorded in association with the selected mobile phone (step S571, FIG. 5a). For example, in the case of the mobile phone “KEITAI_A”, the measurement server IP address “12.34.56.101” is acquired from the correspondence table shown in FIG.

  The CPU 203 reads the measurement method selected on the throughput measurement screen 800 (step S573). For example, in the throughput measurement screen 800 shown in FIG. 8, when “FTP (File Transfer Protocol)” in the measurement method selection field 802 is selected, “FTP” is read as the measurement method.

  The CPU 203 acquires a gateway IP address for connecting to the measurement server acquired in step S571 from the path table 2051 (step S575). For example, for the IP address “12.34.56.101” of the measurement server corresponding to the mobile phone “KEITAI_A”, the gateway IP address “219.108.47” is based on the record 701 in the routing table shown in FIG. .128 ".

  The CPU 203 accesses the measurement server based on the measurement method read in step S573 and transmits a measurement command (step S577). For example, when accessing the measurement server having the IP address “12.34.56.101”, the FTP “get” command is sent via the gateway IP address “219.108.47.128” acquired in step S575. Sent with user authentication information. That is, the packet is transmitted to the IP address “219.108.47.128”.

  For this reason, even if the IP address of the most recently connected mobile phone is set as the default gateway on the measurement PC, communication can be performed using the gateway IP address associated with the measurement server in the route table. . That is, the gateway IP address assigned to each mobile phone can be used reliably.

  At this time, the CPU 203 of the measurement PC requests the measurement server to download the predetermined file by designating the predetermined file in the “get” command.

  In response to the transmission of the measurement command, the CPU 303 of the measurement server transmits a predetermined file in response to the measurement command by the FTP daemon program which is a response means (step S591). For example, a predetermined file read from the hard disk 309 based on the file name specified in the “get” command is transmitted to the measurement PCa.

  Upon receiving the transmission, the CPU 203 of the measurement PCa measures the throughput value while downloading (receiving) the predetermined file transferred from the measurement server via the mobile phone (step S579). For example, the throughput of the cellular phone c1 (“KEITAI_A”) is measured using a program that can monitor the number of packets transmitted and received at the communication port u1.

  For example, if the packet size is 1024 bits and the average number of packets received per second is 10, the transfer rate (bps), which is one of the throughput values, is calculated as 10240 bps (10.24 kbps). Can do. Note that an OS performance monitor function may be used instead of the program capable of monitoring the number of packets.

  The CPU 203 displays the measured throughput value on the display 201 as a measurement result (step S581). For example, the measurement result of a predetermined file received from the measurement server b1 connected via the mobile phone c1 is displayed in the measurement result display field 803.

  The measurement result display field 803 includes “RAS Status” 8031 indicating the status of remote connection, “FtpHost” 8032 indicating the IP address of the FTP connection destination, “Gateway” 8033 indicating the gateway IP address at the time of FTP connection, and the reception size. “Recv kbps” 8034 indicating “Bytes Transmitted / Sec” 8035 indicating the number of transmitted bytes per second, “Bytes Received / Sec” 8036 indicating the number of received bytes per second, and the like are displayed. In addition, a measurement time 8039 when the throughput measurement is performed by transmitting the “FTP” command is also displayed. The measurement time may be obtained from the system clock.

  On the other hand, in the graph display field 805 on the right side of the measurement result display field 803, “Bytes Transmitted / Sec” 8035 indicating the number of transmitted bytes per second and “Bytes Received / Sec” 8036 indicating the number of received bytes per second. The situation about etc. is displayed in a graph. In this graph display, the line l indicates the number of transmitted / received bytes at the current time, and is displayed so that the dot of the graph moves to the left as time passes. As a result, the operator can visually recognize the status of the throughput measurement.

  The CPU 203 records the data content displayed in the measurement result display field 803 on the hard disk 209 as a response result of the measurement method (step S583). For example, “RAS Status” 8031, “FtpHost” 8032, “Gateway” 8033, “Recv kbps” 8034 indicating reception size, “Bytes Transmitted / Sec” 8035, “Bytes Received / Sec” 8036, measurement time 8039, etc. Record the data content about.

  The CPU 203 determines whether or not the measurement stop button 804 has been pressed, and if it has been pressed, ends the processing (step S585, YES). On the other hand, if the measurement stop button 804 is not pressed, the following step S587 is executed.

  In step S587, the CPU 203 determines whether or not the response from the measurement server is completed. If not completed, the CPU 203 returns to step S579 and repeats the same processing (step S587, NO). For example, if the file transfer process by the FTP command is not completed, the throughput measurement per unit time is continued, and the measurement result is displayed on the display 201 and recorded on the hard disk 209.

  On the other hand, if the response from the measurement server is completed, the process returns to step S577, and a new measurement command is transmitted to the measurement server, so that the throughput measurement is performed again (YES in step S587). For example, when “FTP” is selected as the measurement method, “get”, which is a command for receiving a file, is executed again as a measurement command.

  In FIG. 5, the CPU 203 of the measurement PC executes the throughput measurement process shown in steps S571 to S587 for all mobile phones in parallel. For example, the throughput measurement for the mobile phones “KEITAI_B” and “KEITAI_C” in the correspondence table 2053 is executed in parallel, and the execution results are displayed in the measurement result display field 803 and the graph display field 805 on the throughput measurement screen 800, respectively. .

  In this way, by simultaneously performing throughput measurement on all mobile phones connected to the measurement PC, each measurement result can be compared in real time.

1-4. Summary As described above, according to the present invention, a plurality of mobile phones can be connected to one PC device, and throughput measurement can be easily performed without complicating the device configuration. In addition, it is possible to avoid the phenomenon that “the IP address of the most recently connected mobile phone is set as the default gateway on the PC”, which has become a bottleneck when a plurality of mobile phones are connected to one PC. .

  That is, it is possible to simultaneously measure the throughput of each mobile phone while holding one personal computer device and a plurality of mobile phones and moving an arbitrary point.

2-3. Processing Details Processing details in this embodiment will be described with reference to FIG. Note that the route table creation processing is the same as the flowchart shown in FIG. 4 in the first embodiment.

  In FIG. 5b, the CPU 203 of the measurement PCa that has selected the mobile phone acquires the IP address of the measurement server corresponding to the mobile phone, and acquires a predetermined file by the FTP command. At this time, the throughput is measured based on the transfer status of the file being acquired (steps S571 to 579). The measurement result is displayed in the measurement result display field 803 on the display 201, and the measurement time acquired from the system clock is displayed.

  The CPU 203 acquires position information indicating the current throughput measurement point from the GPS receiver 217 (step S580). For example, “NL (north latitude): 34 ° 45′21 ″” and “EL (east longitude): 135 ° 29′51 ″” are acquired as GPS data.

  The CPU 203 displays the acquired GPS data as measurement position data in the measurement result display field 803 together with the measurement result data and the measurement time (step S581). For example, as shown in the measurement result display field 803 of FIG. 8a, the measurement position 8040 is displayed. Further, map information based on GPS data is displayed on the lower right side of the measurement result display field 803. As a result, the operator can visually recognize the throughput measurement position. In addition, the map generation program which inputs GPS data and outputs the positional information on a map should just be used for the display of the said map information.

3. Other Embodiments In the above embodiment, an example in which “FTP” is selected as a measurement method when performing data exchange processing has been described. However, other measurement methods may be used as long as they are effective for throughput measurement. For example, the measurement may be performed based on the execution result of the measurement method of “HTTP (HyperText Transfer Protocol)” or “PING (Packet Internet Groper)”. Further, throughput measurement may be performed using a plurality of measurement methods simultaneously.

  In the above embodiment, one measurement server is associated with each mobile phone. However, if a plurality of IP addresses can be assigned to the measurement server, the system is configured using one measurement server. Also good. That is, a plurality of communication ports may be provided in the measurement server and connected to the measurement PC via each port.
