Description

Communication Quality Measurement System and Method for Wireless Internet {Quality Monitoring System for Wireless Internet and Method}

1 is a communication quality measurement system for a wireless Internet according to an embodiment of the present invention.

2 is a screen of a mobile terminal of a communication quality measurement system for a wireless Internet according to an embodiment of the present invention.

3 is a communication quality measurement method for the wireless Internet according to an embodiment of the present invention.

4 is a method for measuring a communication quality for a peer to peer (P2P) service using a communication quality measuring method for a wireless Internet according to an embodiment of the present invention.

The present invention relates to a communication quality measurement system and method for a wireless internet, and more particularly, to consider not only an internet network that provides a wireless internet service but also logical and physical components for realizing a wireless internet service. The present invention relates to a quality measurement system and a method thereof.

The wireless Internet service refers to a service capable of wirelessly communicating with the Internet based on IEEE 802.16 or 802.11. Wireless internet service is divided into three categories: real-time service, non-real-time service, and best-in-class service.

The real-time service is a type of service (voice communication, video communication, two-way game, telnet, etc.) that requires no transmission delay and guarantees resources during the service. Non-real-time services allow for transmission delays, but resources are guaranteed (file transfers, e-commerce, etc.) during those services. Best-practice services are those that allow transmission delays and are not guaranteed resources during the service (messaging services, web browsing, etc.).

Until now, communication quality measurement for Internet service has been led by internet network operators. Internet network operators have been evaluating the communication quality by simply measuring the performance of the internet network regardless of service classification at the application level, and guaranteeing the communication quality to Internet service subscribers based on this.

For example, K, one of the leading Internet network service companies in Korea, is committed to subscribers based on packet loss rate and packet delay rate through 24-hour ping tests (tests to check whether IP datagrams reach other hosts). Determine quality assurance.

However, the communication quality measurement method that simply measures the performance of the internet network itself may have a lot of difference from the level of service actually provided by the user depending on the service usage tendency of the subscriber or the type of application used by the subscriber.

In addition, the communication quality measurement method as described above may cause complaints to the service provider because only the measurement result provided by the service provider is provided in the situation where the service user side does not grasp the possibility of the cause of the communication quality deterioration.

As such, in order to measure the actual performance quality felt by subscribers using a specific content or service, it is necessary to consider not only the Internet network itself but also the logical and physical components that implement the service except the network as a whole.

 For example, when accessing a web page such as Daum or Naver using the wireless Internet, the communication quality is determined based on a query response time of a domain name system (DNS) and a loading time for each content constituting the web.

Therefore, communication quality of web service should be measured by considering physical DNS server configuration (log and capacity), content server physical configuration (server capacity, network interface connected to server) and logical configuration (file management system algorithm). .

Until now, due to the rapid development of the Internet service providing equipment, large equipment makers insist that performance test by other factors than the Internet network is meaningless. Therefore, the quality of the entire communication service is determined based on the communication quality of the Internet network itself. There were many cases.

However, due to the rapid transition from wired environment to wireless environment, the number of users of personal digital assistants in the form of PDA is rapidly increasing, and the performance of personal digital assistants is comparable with those of wired PCs or laptops. Considering the fact that the performance of the wireless section is not influenced by the surrounding structure and the surrounding environment, the new communication quality measuring device and the communication quality measuring method for the wireless Internet are needed.

3 is a communication quality measurement method for the wireless Internet according to an embodiment of the present invention. Figure 3a schematically shows a communication quality measurement method for a wireless Internet according to an embodiment of the present invention.

Referring to the mobile terminal in which the quality measurement is performed, the measurement mode is first selected (S311). If the selected mode is the server mode (S312), the quality measurement schedule is received (S313).

In the server mode quality measurement test execution step (S314), a quality test is performed on a target host (or service) to perform the quality test algorithm according to the quality measurement schedule.

If the user mode is selected (S315), the user directly operates the menu in the user mode quality measurement test step (S316) to perform a quality test algorithm.

The measurement result measured in the server mode and the user mode is transmitted to the quality control server (S317).

According to the present invention, not only the Internet service provider but also the user of the Internet service can measure the quality by themselves.

The server mode is a quality measurement method by an Internet service provider. The server mode receives a quality measurement schedule by a command message of a quality control server that provides a quality measurement schedule, and performs a quality test on a target host to perform a quality test algorithm.

The user mode executes a quality test algorithm against a target host that will perform the quality test algorithm by the Internet service user.

In the transmission step (S317) transmits the quality test measurement results.

Figure 3b shows a communication quality measurement method in the user-driven step (user mode) of the communication quality measurement method for the wireless Internet according to an embodiment of the present invention.

The user of the mobile terminal selects a user mode that is a user-led quality measurement mode to measure communication quality (S321), and transmits the quality measurement result to the quality management server (S322).

The quality management server generates quality information by using the collected quality measurement result of the communication service (S323) and provides it to the user (S324).

Figure 3b shows a communication quality measurement method in the server-driven step (server mode) of the communication quality measurement method for the wireless Internet according to an embodiment of the present invention.

In the server-driven performance stage (server mode), the communication quality is measured using the mobile terminal according to the quality measurement schedule reflecting the will of the Internet service provider.

First, the quality management server transmits a quality measurement schedule to the mobile terminal (S331).

The mobile terminal measures according to the quality test algorithm included in the quality measurement schedule (S332), and delivers the quality measurement results to the quality control server (S333), and the quality management server uses the collected quality measurement results in detail and usefulness. The quality information is generated (S334) and provided to the user (S335).

3d illustrates a method for measuring communication quality by user mode and server mode in a mobile terminal. According to the present invention, the mobile terminal has two modes of quality measurement mode: server mode and user mode.

The server mode is a measurement mode that can measure the communication service quality at the will of the quality control server operator under the control of the quality control server without the involvement of the user using the mobile terminal.

The user mode is a measurement mode that allows the user to directly measure the quality of the communication service at his mobile terminal and immediately know the result.

When the mobile terminal is driven (S3401) and logged in (S3402), the authentication is approved by the quality control server (S3403), and the mobile terminal requests operation setting information necessary for the operation of the mobile terminal (S3404).

The operation setting information is additional information required when the mobile terminal performs a specific quality test algorithm.

For example, in the case of performing a web load test, the quality test algorithm should not be executed continuously even if the network is disconnected and cannot be measured.

In order to prevent this, the setting value of the timer for detecting the above situation and performing another quality test algorithm by the quality measurement schedule corresponds to the operation setting information. In addition, the IP address of the quality measurement server that will transmit the quality measurement results corresponds to the operation setting information.

In response to the request for the operation setting information, the quality management server provides the operation setting information (S3405).

The mobile terminal receiving the operation setting information updates the operation setting information (S3406).

The above process is not the part seen by the mobile terminal user. From the point of view of the user driving the mobile terminal, only the login process is shown.

The user who successfully executes the login can decide which mode the mobile terminal operates in. It is designed to perform communication service quality measurement by internal procedures even if the user does not decide on his own.

When the user selects the server mode (S3407), the mobile terminal informs the quality control server that the user has selected the server mode (S3410).

The quality control server notified of the user's server mode selection from the mobile terminal configures a quality measurement schedule (S3411), and transmits a quality measurement schedule to the mobile terminal (S3412). The mobile terminal receiving the quality measurement schedule measures the quality of the communication service according to the quality measurement schedule (S3413).

The communication quality measurement result of measuring the quality of the communication service based on the quality measurement schedule is transmitted to the quality management server and collected (S3414, S3415).

The mobile terminal transmits the communication quality measurement result and continues the quality measurement according to the next quality measurement schedule. This series of quality measurement and measurement result reporting is automatically executed without any intervention of the mobile user, enabling the quality measurement of a wide range of communication services at the will of the Internet service provider.

The mobile terminal user can monitor the quality measurement status of the server mode through the screen (Fig. 2c) that displays the simple items currently being executed in the server mode.

Further, when the user of the mobile terminal switches the measurement mode to the user mode while the server mode is running (S3422), the mobile terminal determines whether the quality measurement schedule is currently executed (S3426) and stops the quality measurement ( S3427), and transmits the quality measurement result performed up to this time to the quality management server (S3428), saves the log (S3429), and starts the execution of the user mode (S3421).

In user mode, a user of a mobile terminal directly measures communication quality for various types of communication services by using a communication service measurement function in the mobile terminal. When the measurement mode is switched to the user mode (S3409), the quality control server is notified of the user mode switch (S3416).

After notifying the mode conversion, the user of the mobile terminal performs communication service quality measurement using the active measurement quality test algorithm and the P2P measurement quality test algorithm provided by the mobile terminal (S3417).

The results measured by executing each quality test algorithm are transmitted to the quality control server (S3418), and the user of the mobile terminal can immediately see the measurement results on the screen provided in each measurement function window. The mobile terminal user determines whether to continue measuring communication service quality in the user mode (S3420).

If the user of the mobile terminal does not perform any operation, the mobile terminal may forcibly switch the measurement mode to the server mode by operating a timer (S3434).

In addition, it is possible to switch to the server mode at the will of the mobile terminal user during the measurement of the communication service quality of the user mode (S3423).

When the measurement mode is switched at the user's will, the mobile terminal checks whether there is a quality measurement schedule that has been measured before (S3430), and if the quality measurement schedule is in operation, stops measuring the quality of the communication service (S3431). The quality measurement result measured until then is transmitted to the quality management server (S3432), the log is stored (S3433), and the server mode is executed (S3419).

As such, the user of the mobile terminal directly measures the communication service quality using the server mode and the user mode, or supports the communication service quality measurement of the Internet service provider.

In addition, when the mobile terminal starts to log in but does not explicitly select the measurement mode (S3408), the mobile terminal operates a timer according to the operation setting information (S3424), thereby automatically switching to the server mode, thereby allowing the Internet to Support service provider quality measurements.

4 is a method for measuring a communication quality for a P2P service using a communication quality measuring method for a wireless Internet according to an embodiment of the present invention.

The communication quality measuring method according to the present invention provides a communication quality measurement for a P2P service which is specialized in the use of a PDA type mobile terminal in the wireless Internet.

According to the present invention, it is possible to measure not only the communication quality of a specific service between a mobile terminal and a service providing server in a wireless Internet but also the communication quality of a P2P service between the mobile terminal and the mobile terminal.

Figure 4a is a flow of messages sent and received between the quality management server and the mobile terminal for measuring the communication quality of the P2P service in the user mode.

There are two quality test algorithms that can be executed in the user mode: quality test algorithms for active measurement services and quality test algorithms for P2P measurement services. Referring to FIG. 2D, when the P2P icon of the P2P measurement service zone shown in FIG. 2D is clicked, a quality test algorithm for measuring communication quality of the P2P measurement service is executed.

When the quality test algorithm for communication quality measurement of the P2P measurement service is executed, the mobile terminal requests a list of target terminals capable of P2P measurement service from the quality control server (S411). The quality management server transmits the target terminal list to the mobile terminal (S412).

2L is shown in the user's mobile terminal. Referring to FIG. 2L, a target terminal is selected from a user's host list, and a quality test algorithm to be executed with the target terminal is selected. Figure 2L illustrates Ping, UDP, download, and custom tests as a user selectable quality test algorithm.

2M is a screen shown when the UDP quality test algorithm is selected in the P2P measurement service. 2N is a screen shown when the download quality test algorithm is selected in the P2P measurement service. 2o is a screen shown when the Ping quality test algorithm is selected in the P2P measurement service.

After the selection of the target terminal for executing the quality test algorithm as shown in FIGS. 2M, 2N and 2O (S413), when the Start icon is clicked as shown in FIG. 2L, the mobile terminal requests for P2P measurement preparation for the target terminal ( S414), and the target terminal responds (S415).

The mobile terminal receiving the response to accept performs the quality test algorithm of the target terminal and the P2P service (S416).

The mobile terminal stores the quality measurement result and transmits it to the quality control server (S417). On the other hand, the mobile terminal and the target terminal that has performed the quality measurement of the P2P service also store the quality measurement result and transmit it to the quality management server (S418).

4b is a flow of messages exchanged between a quality control server and a mobile terminal for measuring communication quality of a P2P service in server mode.

The quality management server transmits a list of target terminals capable of measuring communication quality of the P2P service to the mobile terminal (S421). The list of target terminals is included in the quality measurement schedule and transmitted.

The mobile terminal inquires whether it is possible to measure the quality of the P2P service for the target terminal (S422), and the target terminal responds thereto (S423).

The mobile terminal receiving the response that it is possible performs the quality test algorithm of the P2P service based on the target terminal and the quality measurement schedule (S424).

The mobile terminal transmits the quality measurement result of the P2P service to the quality management server (S425). The target terminal also stores the quality measurement result of the P2P service and transmits it to the quality management server (S426). The steps S422-S426 continue to execute the target terminals in the target terminal list in order.

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
