Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

In embodiments and examples of the present invention, the term 'traffic' may be replaced with 'usage'.

In addition, the measurement index may mean a measurement index for the Internet. Thus, the 'measurement indicator' may be replaced with 'internet indicator' or 'internet measurement indicator'.

The mobile terminal refers to a device that transmits and receives information through a wireless network.

Wireless networks include, for example, Generation G mobile networks, fourth generation mobile networks, WiBRO, wireless Wi-Fi, and the like.

The mobile terminal may include a smartphone, a feature phone for setting a network environment, a portable computer capable of wireless communication, a tablet capable of wireless communication, and the like.

The mobile terminal may exchange information via a wired network such as an Ethernet and a universal serial bus.

In addition, an "application" refers to a program that exchanges information through a wireless network operating in a mobile terminal. For example, an application includes a web browser, an app, and a program for a mobile terminal. In addition, an application may mean some of the components of an operating system (OS) of a mobile terminal.

As described above, basically, the measurement indices for the wired network can be used as the measurement indices of the mobile network, and the measurement indices specific to the mobile network can be calculated.

For example, metrics of various mobile networks may be used, such as the number of times the application is run and usage traffic for each site on the web screen running within the application (eg, total usage time, UU, PV, QC, etc.).

In addition, due to the characteristics of an application for a mobile network, the amount of usage (eg, usage time) when the application uses only embedded functions without being connected to the Internet may also be included as a measurement index of the mobile network. Which mobile network the mobile terminal uses may be a measure of the mobile network.

1 is a table comparing the mobile traffic measurement technology according to an embodiment of the present invention.

In FIG. 1, for each of the virtual private network (VPN) scheme 110, the meter scheme 120, the carrier cooperative scheme 130, and the description scheme 140, according to the type of traffic data. The traffic measurement possibility of the mobile network is shown.

"○" of symbols displayed for traffic data indicates that measurement is possible. That is, the "○" is displayed on the web general index for the VPN method 110 means that the web general index can be measured through the VPN method 110. The symbol "Ⅹ" indicates that the measurement is difficult or impossible. The symbol "Δ" indicates that some measurement is possible but some measurement is difficult or impossible.

In the following, the VPN method 110, the meter method 120, the service provider cooperation method 130, and the questionnaire method 140 for calculating the measurement index are reviewed, respectively.

The VPN method 110 measures network traffic based on packets transmitted through the VPN.

In general, a VPN is established by a subject (hereinafter, abbreviated as a measuring subject) that measures traffic of a mobile network.

The measurement subject may subscribe a certain number of panels as a user of the VPN network. Each of the subscribed users may be mapped to an IP (internet protocol) address of the VPN network.

The measurement subject may extract the usage history of each of the panels based on a packet transmitted from each of the panels (that is, a packet transmitted from the terminal used by each of the panels).

Based on the extracted usage history, a measurement index may be calculated. In addition, the measurement index may be calculated by applying a population proportional expansion factor to the usage history of each of the panels. In general, the VPN method 110 may measure web general indicators, web search QCs, application search QCs, and start pages among data types, and may partially measure traffic for each application.

That is, the VPN method 110 may check traffic for a connected application, but may not be suitable for calculating a measurement index for stand-alone that does not use a network. You may not be able to.

The meter method 120 measures network traffic based on a user's usage history (ie, activity) recorded by a meter operating in a mobile terminal.

In the meter system 120, a meter is used. A meter is an application that monitors a usage pattern of a mobile terminal (eg, details of transmission and reception of information through a network).

In order to use the meter method 120, a certain number of panels recruited by the measurement subject install a meter on their mobile terminal. The mobile terminal can download the meter over the network.

In order to use the metering scheme 120, a default web browser installed within the mobile terminal may be set to record the URL on the meter during web calls and movements. That is, the meter may record the usage history of the user of the mobile terminal.

The meter calls the unique resource locator (URL) of the default web browser by referring to an application programming interface (API) (hereinafter, referred to as a built-in API) basically provided by an operating system of a mobile terminal. And you can see the changes.

The meter can measure web-related metrics based on these calls and confirmations.

In addition, the meter can monitor the memory status (that is, what occupies the memory) with a resident program to check whether the application is running. That is, the meter can determine whether the application is executed by checking the memory of the mobile terminal, and measure the measurement index related to the application.

In general, the meter runs in the background on the mobile terminal. In fact, other applications that send and receive information over the network run in the foreground.

Therefore, a mobile terminal that does not support multitasking or uses an operating system that only partially supports multitasking may not use the metric system 120 at its source.

The mobile terminal (or meter) may transmit the usage history of the recorded user (that is, the user of the mobile terminal among the panels) to the server of the measurement subject.

The measurement subject may calculate the measurement index based on the usage history transmitted. In addition, the measurement subject may calculate a measurement index by applying a population proportional expansion coefficient to each usage history of the panels.

In general, the meter method 120 may measure web general indicators, web search QCs, and start pages among data types, and may partially measure traffic for each application. In addition, the meter method 120 may not be suitable for measuring the application search QC or may not measure the application search QC.

That is, when the meter method 120 is used, only some measurement indicators such as usage time and the number of accesses may be checked for each application.

The carrier alliance scheme 130 is a method of receiving a usage history (ie, a network usage history of an individual telecommunication company) of individual telecommunication company users through an alliance with telecommunication companies and measuring network traffic based on the provided usage history. The above usage history may be all data.

In order to use the carrier alliance scheme 130, an alliance between the measurement subject and the carriers is required in advance. Thus, affiliation needs of carriers for measuring network traffic are required.

In general, the carrier association method 130 may measure web general indicators, web search QCs, application search QCs, and start pages among data types, and may partially measure traffic for each application.

The survey method 140 is a method of obtaining a response according to one's memory from a user of a mobile network through a questionnaire asking a usage behavior and calculating a measurement index based on the obtained response.

When the survey method 140 is used, all data types can be measured. However, the response obtained due to the nature of the questionnaire method 140 has a limitation in accuracy. Thus, the data types measured by the questionnaire method 140 may be inaccurate compared to the data types measured by the other methods.

2 is a table comparing in detail the VPN method 110 and the meter method 120 according to an embodiment of the present invention.

First, the characteristics of the VPN method 110 will be described in detail.

When the measurement method is the web, the VPN method 110 may measure all the measurement indicators without restriction on the web browser used.

If the measurement target is an application, the VPN method 110 may measure most measurement indicators. However, the measurement target of the VPN method 110 may be limited to the connected application. VPN method 110 may measure the total amount of search application QC. Among the URLs over the network, the total amount of the corresponding URLs can be checked by designating in advance the QC URL having the code of the search application.

The meter method 120 may measure a measurement index related to the web only when a web browser using the URL check API is used when the measurement target is the web. That is, when a browser using a URL check API is used, the meter method 120 may not measure a web-related measurement indicator. Such URL checking API is generally provided by an operating system or the like.

Next, the characteristics of the meter system 120 will be described in detail.

When the measurement object is an application, the meter method 120 may measure the measurement indicator in the memory resident state regardless of the communication state (that is, whether the device is connected).

When the meter method 120 is used, a unique user for each application, a total use time for each application, a driving count for each application, and an active user for each application may be measured by a resident program (that is, a meter).

The meter method 120 may not measure the total amount of PV and search application QC for each application.

As described above, the meter method 120 may measure the measurement indicator only for the web browser using the URL check API. Therefore, URL information in an application using other APIs other than the built-in URL check API may not be measured by the meter method 120.

Therefore, the advantages and disadvantages of the VPN method 110 and the meter method 120 can be summarized as follows.

When the VPN scheme 110 is used, data for mobile traffic measurement is obtained by a VPN server or the like. Thus, the limitations of individual mobile terminals can be overcome. For example, even for traffic generated by a mobile terminal using an operating system that does not support or partially supports multitasking, data for mobile traffic measurement may be collected.

In addition, the VPN method 110 may measure mobile traffic through a consistent measurement method without distinguishing between applications and web browsers operating in the mobile terminal.

VPN method 110 may also check the URL used in the application. Thus, the search QC and PV indicators of all services can also be calculated. In particular, in the mobile environment (ie, mobile terminal), it is generally known that the search portion through the application is higher than the wired environment (ie, a terminal that operates by wire such as a PC).

Due to the characteristics of mobile traffic measurement, the total amount of PV and search application QC by application accounts for a large portion of the total measurement indicators. 120 may be considered superior.

In addition, two programs (that is, an application for transmitting and receiving actual information and a meter) must be executed in order for the meter method 120 to be used. On the other hand, the VPN scheme 110 only requires that a VPN be established in the mobile terminal. Thus, when the VPN scheme 110 is used, the load on the mobile terminal may be less.

The aspect of usage of network bandwidth of the mobile terminal is examined. Even if the mobile terminal is set to use a VPN, only the destination (i.e., the VPN server) to which the mobile terminal transmits the information is changed, and the amount of information transmitted by the mobile terminal itself does not change (large).

Thus, even if the VPN scheme 110 is used, the user does not have to bear additional communication charges. On the other hand, when the metric system 120 is used, information for measuring traffic generated in the mobile terminal should be transmitted to an external server for statistics. Thus, by using the metric system 120, additional communication costs May occur.

3 illustrates a VPN according to an embodiment of the present invention.

The VPN may be roughly composed of a mobile terminal 310, a VPN server 320 and an external server 330.

The mobile terminal 310 is connected to the Internet through the wireless network or the wired network described above. The mobile terminal 310 exchanges information with an external server 330 through the Internet.

The external server 330 may be a web server that provides a specific service to the mobile terminal 310 and a personal computer (PC), such as a web server of a search site.

If the mobile terminal 310 does not use a VPN (that is, no VPN is set in the mobile terminal 310), the mobile terminal 310 directly accesses the external server 330 through the Internet and downloads data. Give and take

On the other hand, when the mobile terminal 310 uses a VPN (that is, when the mobile terminal 310 is set to use the VPN provided by the VPN server 320 by a user or the like), the mobile terminal is connected to an external server through the Internet. Information exchanged with the 330 is via the VPN server 320.

That is, information that should be transmitted to the external server 330 by the mobile terminal 310 is first transmitted from the mobile terminal 310 to the VPN server 320, and then the information transmitted by the VPN server 320 is transferred to the external server ( 330). In addition, information that the external server 330 needs to transmit to the mobile terminal 310 is first transmitted from the external server 330 to the VPN server 320, and then, the information transmitted by the VPN server 320 is transmitted to the mobile terminal. Forward to 310.

Information transmitted and received between the mobile terminal 310 and the external server 330 may be transmitted in the form of a packet. The VPN server 320 may monitor packets transmitted and received between the mobile terminal 310 and the external server 330 in the above-described delivery process.

The packet may be a TCP / IP packet, and the VPN server 320 may monitor URL and agent information of a header of the TCP / IP packet.

4 is a flowchart illustrating a traffic measuring method of a mobile network according to an embodiment of the present invention.

This embodiment may be performed by the VPN server 320 or another server linked with the VPN server 320.

The mobile terminal 310 has been set up to communicate via a VPN.

In operations 410 and 420, authentication for the mobile terminal 310 is performed.

In operation 410, a request for authentication required to use a VPN is received from the mobile terminal 310. The request may include identification information (eg, an ID and password) for identifying the mobile terminal 310 and / or the user of the mobile terminal 310.

In operation 415, authentication is performed using the identification information, and if authentication is successful, authentication is granted to the mobile terminal 310 or the user of the mobile terminal 310.

In operation 420, the mobile terminal 310 is assigned an IP address on the VPN.

The IP address may be a reserved IP (ie, static IP or static IP).

In operation 430, a packet is received from the mobile terminal 310 via a VPN.

The packet is generated by one or more applications installed in the mobile terminal 310. The application includes an app installed through a web browser, a market, etc. installed in the mobile terminal 310, and a program installed through a network or a memory card.

In operation 435, measurement information collected by the mobile terminal is received from the mobile terminal 310.

For example, when the mobile terminal 310 is equipped with a meter, the mobile terminal 310 may collect meter measurement information by a meter measurement method, and in operation 435, meter measurement collected from the mobile terminal 310. Information can be transmitted.

In operations 440-460, network traffic is measured based on the received packet.

In operation 440, the header of the received packet is analyzed.

The header of the packet analyzed in operation 440 may be a header of a packet transmitted through an HTTP request.

In operation 450, traffic measurement information for traffic measurement is extracted in the received packet based on the above analysis.

The traffic measurement information includes an IP address on the VPN given to the mobile terminal 310, a user ID on the VPN given to the user of the mobile terminal 310, an application in the mobile terminal 310 that generated the packet, and the mobile terminal 310. One or more of a user agent of (i. E., A mobile terminal 310 operating system and / or a browser of the mobile terminal 310) and a time stamp of the packet.

In operation 460, network traffic is measured by counting packets that meet a particular condition based on the analysis above.

The specific condition may mean whether the packet corresponds to a specific string. That is, the packet satisfying the specific condition may be a packet corresponding to the specific string.

For example, in operation 460, network traffic may be measured by counting packets corresponding to (or comprising, a particular string) based on the analysis above.

In addition, the specific condition may mean whether the packet corresponds to a specific URL pattern. That is, the packet satisfying the specific condition may be a packet corresponding to the specific URL pattern.

For example, in operation 460, network traffic may be measured by counting packets corresponding to a particular URL pattern based on the analysis above.

A string or a specific URL pattern for measuring network traffic can be arbitrarily specified.

The above specific conditions may be one or more. That is, in operation 460, network traffic may be measured for each of the one or more conditions by counting packets that satisfy a particular condition for each of the one or more conditions.

By using the measured network traffic for each of the one or more conditions, network traffic can be analyzed on a conditional basis, and metrics can be generated.

In addition, the specific URL pattern (or string) may be one or more. That is, network traffic may be measured for each of the one or more URL patterns by counting a corresponding packet for each of the one or more URL patterns in operation 460.

By using the measured network traffic for each of the one or more URL patterns, network traffic may be analyzed for each URL pattern, and measurement metrics may be generated.

For example, network traffic may be analyzed based on the packet's IP address, URL pattern, user agent, and time stamp. Also, instead of the IP address of the packet, a user ID on the VPN can be used.

Network traffic may be measured based on the traffic measurement information described above. In addition, network traffic may be classified and measured according to the above-described traffic measurement information. For example, one or more network traffic may be measured according to a particular operating system or web browser.

Network traffic may be measured by additionally using the measurement information collected by the mobile terminal 310.

The measurement information collected by the mobile terminal 310 may be meter measurement information collected by a meter measurement method. That is, the VPN method 110 and the meter method 120 may be mixed to measure network traffic.

Operations 450 and 460 may be performed simultaneously. For example, the IP address, URL pattern, user agent and time stamp of the packet can be extracted at the same time.

In operation 470, one or more measurement metrics are generated based on the measured network traffic.

This embodiment uses a VPN scheme 110. Thus, as described above with reference to FIG. 1, a search QC may be included among the one or more measurement metrics generated at operation 470.

The measured network traffic can be provided in various forms. For example, the measured network traffic may be provided in the form of a log.

If network traffic is measured per panel, the population proportional expansion factor for the panels may be applied in generating measurement metrics. Logic for applying one or more proportional expansion coefficients may be defined, and measurement indicators may be generated by applying a population proportional expansion coefficient generated according to the defined logic.

Technical contents according to an embodiment of the present invention described above with reference to FIGS. 1 to 3 may be applied to the present embodiment as it is. Therefore, more detailed description will be omitted below.
