Description

트래픽 채널 검출장치 및 방법과 기록매체Traffic channel detection device and method and recording medium
본 발명은 무선 네트워크 부하의 주요 원인인 무선단말장치에서의 트래픽 채널 생성을 검출하기 위한 것이다.The present invention is to detect the traffic channel generation in the wireless terminal device which is the main cause of the wireless network load.
스마트폰의 보급 이후 개인의 단말 사용 패턴은 음성통화에서 데이터 통신위주로 급속히 전환되고 있다.Since the spread of smartphones, personal terminal usage patterns have been rapidly shifting from voice calls to data communication.
도면 1의 모바일(무선) 데이터 트래픽 지표에서 보는 바와 같이, 향후 10~15년간 약 26배의 모바일 트래픽 증가가 예상되며, 2010년 개인이 하루에 사용하는 모바일 데이터량은 15MB수준이었으나, 2020년에 1GB에 이르게 될 수 있다.As shown in the mobile (wireless) data traffic indicator of FIG. 1, mobile traffic is expected to increase by about 26 times over the next 10 to 15 years, and the amount of mobile data used by individuals in 2010 was 15MB, but in 2020 It can reach 1GB.
이러한, 모바일 트래픽 증가는 이동통신사의 수익성 및 서비스 품질에 직접적으로 영향을 미치는 요인으로 작용하며, 서비스 사업자인 이동통신사의 장비증설을 수반하며, 이에 따른 수익악화가 불가피한 실정이며, 모바일 네트워크를 이용하는 사용자 또한 데이터 통신 속도 지연에 따른 서비스 불만족이 증가하게 된다. This increase in mobile traffic directly affects the profitability and service quality of mobile carriers, and involves the expansion of equipment of mobile carriers as service providers. As a result, profit deterioration is inevitable. In addition, service dissatisfaction is increased due to data communication speed delay.
이에 따라, 이동통신사들은 투자부담 감소와 서비스 품질보장을 위해 네트워크 인프라를 효율적으로 활용해야 하는 과제에 봉착했으며 현재의 솔루션에는 한계가 존재하므로 예측가능성과 실시간 통제가 보장되는 대안이 필요한 실정이다.As a result, mobile operators face the challenge of efficiently utilizing network infrastructure to reduce investment and ensure quality of service, and current solutions have limitations, requiring alternatives that guarantee predictability and real-time control.
한편, 도면 2에서 보는 바와 같이, 모바일 네트워크 혼잡의 주요 요인은 무선단말장치에 설치된 각종 애플리케이션을 통한 통신망 상의 서버와의 트래픽 채널 생성이다.On the other hand, as shown in Figure 2, the main factor of mobile network congestion is the generation of traffic channels with the server on the communication network through various applications installed in the wireless terminal device.
즉, 무선단말장치에서 통신망 상의 서버와 하나의 트래픽 채널을 생성하기 위해서는 기지국의 위치확인 등 통신망 상의 장치들과 수십여번의 시그날 통신이 선행되어야 하며, 이러한 시그날 통신은 대용량의 패킷 전송보다 통신망 상에 더 커다란 부하를 유발한다.That is, in order to generate a traffic channel with a server on a communication network in a wireless terminal device, dozens of signal communication must be preceded by devices on the communication network such as the location of a base station, and such signal communication is performed on the communication network rather than a large packet transmission. Cause a greater load.
또한, 데이터 폴링을 시행하는 애플리케이션들은 짧게는 수분에서 수십분 간격으로 애플리케이션 서버와 트래픽 채널을 생성하고 해제하는 과정을 반복하게 되는 바, 모바일 네트워크 과부하의 주요 요인으로 작용하고 있는 실정이다. In addition, applications that perform data polling repeatedly create and release application servers and traffic channels every few minutes to several tens of minutes, which is a major factor in overloading mobile networks.
결론적으로, 네트워크 혼잡에 따른 이동통신 사업자의 막대한 비용소모와 무선단말장치 사용자들의 서비스 불만족을 해결해야 하며, 무선단말장치에 구비된 복수개의 애플리케이션을 통한 과도한 트래픽 채널 생성 및 해제와 이를 통한 과도한 시그널 통신 부하를 제어하기 위해서는 무선단말장치와 특정 서버들 간 트래픽 채널 생성 횟수와 과도한 트래픽 채널 생성을 유도하는 서버 정보와 트래픽 채널 생성 및 해제에 따른 시그널 통신 부하량 등을 모니터링 할 수 있어야 하나, 통신망 시스템 상에서 이러한 모니터링을 보다 쉽고 편리하게 처리할 수 있는 방안이 전무한 실정이다. In conclusion, it is necessary to solve the enormous cost consumption of mobile operators and the service dissatisfaction of users of wireless terminal devices due to network congestion, and to create and release excessive traffic channels through multiple applications in wireless terminal devices and excessive signal communication through them. In order to control the load, it is necessary to monitor the number of traffic channel generation between the wireless terminal device and specific servers, server information inducing excessive traffic channel generation, and signal communication load due to traffic channel creation and release. There is no way to handle the monitoring more easily and conveniently.

도면 3을 참조하면, 본 발명의 실시 방법에 따른 트래픽 채널 검출장치(100)는, 수집부(10)와, 전처리부(20)와, 확인부(30)와, 분석부(40)와, 검출부(50)를 포함하여 구성된다.Referring to FIG. 3, the traffic channel detecting apparatus 100 according to the embodiment of the present invention includes a collecting unit 10, a preprocessor 20, a confirming unit 30, an analyzing unit 40, It is comprised including the detection part 50.
여기서, 상기 트래픽 채널 검출장치(100)는 실시예 설명을 위해 도면 상에는 단일 장치로 도시되어 있으나, 상기 각각의 구성부가 각각 하나 이상의 장치 또는 서버로 분리되어 구성될 수 있다.Here, the traffic channel detection apparatus 100 is illustrated as a single device in the drawings for the purpose of describing the embodiments, but each of the components may be separately configured into one or more devices or servers.
도면 3을 참조하면, 상기 수집부(10)는, 통신망을 통해 복수개 무선단말장치(200) 및 복수개 서버(300) 간 상호 송수신하는 복수개 패킷을 수집 또는 캡쳐하는 역할을 수행한다.Referring to FIG. 3, the collection unit 10 collects or captures a plurality of packets transmitted and received between the plurality of wireless terminal devices 200 and the plurality of servers 300 through a communication network.
본 발명의 일 실시방법에 따르면, 무선단말장치(200)가 서버(300)(게임, 웹, 채팅, 유튜브 등)와 통신을 할 때, 기본적으로 무선단말장치(200)에서 발생된 패킷은 GGSN(Gateway GPRS Support Node)을 거치면서 TCP/IP프로토콜로 변환되어 해당하는 서버(300)로 전달되는데, 무선단말장치(200)와 서버(300) 간에 주고 받던 통신에 문제를 발생시키지 않으면서 패킷들을 분석해야 하는 바, 상기 수집부(10)는 패킷을 복제한 후, 복제된 패킷을 전처리부(20)로 전달하는 것이 바람직할 것이다.According to the exemplary embodiment of the present invention, when the wireless terminal device 200 communicates with the server 300 (game, web, chat, YouTube, etc.), the packet generated by the wireless terminal device 200 is basically GGSN. (Gateway GPRS Support Node) is converted to the TCP / IP protocol and transmitted to the corresponding server 300, the packets are transmitted without causing problems in the communication between the wireless terminal device 200 and the server 300 As it should be analyzed, it is preferable that the collection unit 10 replicates the packet and then transfers the duplicated packet to the preprocessor 20.
종래 무선단말장치(200)에서의 트래픽 채널 생성 및 해제 프로세스를 보여주는 일실시예도인 도면 4를 참조하면, 무선단말장치(200)는 데이터 송수신시 기본상태(idle)에서 Cell_DCH(3G의 경우) 또는 ECM Connected(4G의 경우)상태로 변경되는데, 상태가 변경이 되었다는 것은 통신망 상의 장치(기지국과 교환국을 하나 이상 포함하는 통신망 상의 장치 내지 코어네트워크)와의 시그널을 통한 통신을 통해서 트래픽 채널이 생성되었다는 것을 의미할 수 있다.Referring to FIG. 4, which is an exemplary view illustrating a process of generating and releasing a traffic channel in a conventional wireless terminal device 200, the wireless terminal device 200 may transmit Cell_DCH (in case of 3G) in a basic state when transmitting and receiving data. It changes to ECM Connected (4G) state, which means that a traffic channel is created through communication with a device on a network (device or core network on a network that includes one or more base and switching stations). Can mean.
트래픽 채널이 생성된 상태에서는 무선단말장치(200)와 통신망 상의 장치 간 별도의 시그널 통신 없이 사용자 데이터를 주고받을 수 있으며, 이렇게 생성된 트래픽 채널은 일정 시간 동안 데이터가 이동하지 않을 경우, 무선단말장치(200)는 자동으로 idle상태로 변경되며 이를 도먼트(dormant)상태라고 할 수 있다.In the state where the traffic channel is generated, user data can be transmitted and received without a separate signal communication between the wireless terminal device 200 and the device on the communication network. When the traffic channel is not moved for a predetermined time, the wireless terminal device The 200 is automatically changed to the idle state, which may be referred to as a dormant state.
여기서, 도먼트 상태로 진입하는 방식은 여러가지가 존재할 수 있다. 예를 들어, 무선단말장치(200)가 직접 dormant상태로 변경하는 FD(Fast Dormancy)와, 코어네트워크에서 무선단말장치(200)가 dormant상태로 들어가도록 지시하는 NCFD(Network Controlled Fast Dormancy)방식이 예시될 수 있다.Here, there may be various ways of entering the doping state. For example, FD (Fast Dormancy) that the radio terminal device 200 changes to the dormant state directly, and NCFD (Network Controlled Fast Dormancy) method for instructing the radio terminal device 200 to enter the dormant state in the core network May be exemplified.
즉, 무선단말장치(200)는 데이터 송수신 상태에 따라서 idle상태에서 Cell_DCH(또는 ECM Connected)상태로 변환하면서 트래픽 채널을 생성하고, 데이터 전송 이후 일정시간 동안 데이터의 이동이 없을 시 다시 idle상태(트래픽 채널을 해제)로 계속해서 변화하면서 트래픽 채널의 생성 및 해제를 반복하는데, 이러한 트래픽 채널 생성 및 해제 과정은 무선 네트워크 상의 부하의 주요 원인으로 작용하는 바, 몇 번의 트래픽채널이 생성되었는지를 검출하게 되면, 무선 네트워크 상의 부하 문제를 해결할 수 있는 기초 자료로 활용 가능하게 된다.That is, the wireless terminal device 200 generates a traffic channel while converting from the idle state to the Cell_DCH (or ECM Connected) state according to the data transmission and reception state, and again idles when there is no data movement for a certain time after the data transmission. The channel is repeatedly created and released while the channel is continuously released. This traffic channel creation and release process is a major cause of the load on the wireless network. When the number of traffic channels is detected, As a result, it can be used as a basic data for solving the load problem on the wireless network.
본 발명에 따른 전처리부(20)는, 상기 수집부(10)가 수집 또는 캡쳐하는 패킷들을 각각의 무선단말장치(200) 고유 식별정보별로 패킷 수집 또는 캡쳐 시간 순으로 정렬하는 역할을 수행한다.The preprocessing unit 20 according to the present invention serves to sort the packets collected or captured by the collection unit 10 in order of packet collection or capture time for each unique identification information of the wireless terminal device 200.
통신망에서 무선단말장치(200)와 서버(300) 간 주고받는 패킷은 여러 무선단말장치(200)와 여러 서버(300)간의 통신패킷들이 섞여있기 때문에, 특정 무선단말장치(200)와 특정 서버(300) 간 형성되는 트래픽 채널을 확인하기 위해서는 상기 수집부(10)가 수집 또는 캡쳐하는 패킷들을 각각의 무선단말장치(200) 고유 식별정보별로 먼저 분류해야 하는 바, 상기 전처리부(20)에서 상기 수집부(10)가 수집 또는 캡쳐하는 패킷을 무선단말장치(200) 고유 식별정보(예를들면, IP)별로 분류하되, 패킷 수집 또는 캡쳐 시각 순으로 정렬하여 분류하는 것이다.Since the communication packets between the wireless terminal device 200 and the server 300 in the communication network are mixed with the communication packets between the various wireless terminal device 200 and the server 300, the specific wireless terminal device 200 and the specific server ( In order to identify the traffic channel formed between 300, the packets collected or captured by the collection unit 10 should be first classified by the unique identification information of each wireless terminal device 200. In the preprocessing unit 20, Packets collected or captured by the collector 10 are classified according to the unique identification information (for example, IP) of the wireless terminal device 200, and sorted in the order of packet collection or capture time.

Confirmation unit 30 according to the embodiment of the present invention, for each of the packets arranged through the preprocessor 20 serves to determine whether the time interval with the previous packet is n seconds or more. The analysis unit 40 according to the embodiment of the present invention, if the section is confirmed that the time interval with the previous packet is n seconds or more, as a result of the confirmation of the check unit 30, the wireless terminal device every time the section is generated for more than n seconds ( And counting the number of traffic channel generations in step 200).
그리고, 본 발명의 다른 일 실시방법에 따른 확인부(30)는, 통신사 시스템을 통해 도먼트 타임(Dormant Time)-트래픽 채널 생성 후 일정 시간동안 패킷 송수신이 미발생하여 자동으로 트래픽 채널을 해제하는데 소요되는 시간-정보를 확인하고, 상기 전처리부(20)를 통해 정렬된 각각의 패킷들에 대하여 이전 패킷과의 시간 간격이 도먼트 타임 이상인지를 확인하는 역할을 수행하며, 본 발명의 실시방법에 따른 분석부(40)는, 상기 확인부(30)의 확인결과, 이전 패킷과의 시간 간격이 도먼트 타임 이상인 구간들이 확인되면, 상기 도먼트 타임 이상인 구간 발생시마다 상기 무선단말장치(200)에서의 트래픽 채널 생성 횟수를 한 개씩 카운팅하는 역할을 수행할 수 있다.In addition, the identification unit 30 according to another embodiment of the present invention automatically releases the traffic channel due to no transmission / reception of packets for a predetermined time after generating a Dormant time-traffic channel through a communication company system. It checks the time-information required, and checks whether the time interval with the previous packet is greater than the dome time for each packet arranged by the preprocessor 20, the method of the present invention The analysis unit 40 according to the check result, when the section is confirmed that the time interval with the previous packet is greater than the dome time, as a result of the check, the wireless terminal device 200 each time the interval occurs more than the dome time It can serve to count the number of times the traffic channel is generated in.
여기서, 트래픽 채널이 발생했는지를 산정하려면 도먼트 타임을 정확히 알아야 하는데, FD, 혹은 NCFD로 dormant 모드로 변경되는 시간은 통신사, 단말, 지역별로 상이하기 때문에 상기 확인부(30)에서 통신사 시스템을 통해 도먼트 타임을 확인할 수 있는 것이며, 이 경우, 확인부(30)를 통한 도먼트 타임 확인 시점은 상기 확인부(30)에서 상기 전처리부(20)를 통해 정렬된 각각의 패킷들에 대하여 이전 패킷과의 시간 간격이 상기 도먼트 타임 이상인지를 확인하기 이전 어느 시점이든 무관하다. Here, in order to calculate whether a traffic channel has occurred, it is necessary to know the dormant time exactly. Since the time of changing to the dormant mode by FD or NCFD is different for each communication company, terminal, and region, the confirmation unit 30 uses a communication company system. It is possible to check the doment time, in this case, the time of confirmation of the dome time through the confirmation unit 30 is the previous packet for each of the packets arranged by the preprocessor 20 in the confirmation unit 30 It is irrelevant at any point before checking whether the time interval with is greater than or equal to the doment time.
한편, 본 발명의 다른 일 실시 예에서는 통신사 시스템을 통해 획득되는 도먼트 타임을 타임 정보로서 이용하는 것을 설명하고 있으나 기타 다른 시간 정보를 이용하는 것도 가능할 수 있다. 예를 들어, 확인부(30)는 통신사 시스템을 통해 획득되는 다른 시간 정보에 기반하여 비교 확인할 수 있다. 예를 들어, 확인부(30)는 이전 패킷과의 시간 간격이 통신사 시스템을 통해 획득되는 시간 정보 이상인지를 확인할 수 있다.Meanwhile, although another embodiment of the present invention describes the use of the dome time obtained through the telecommunication company system as the time information, other time information may be used. For example, the verification unit 30 may compare and confirm based on other time information obtained through the telecommunication company system. For example, the checker 30 may check whether a time interval with a previous packet is greater than or equal to time information obtained through a communication company system.
도면 6 내지 도면 7은 상기 확인부(30)와 분석부(40)를 통해 본 발명의 실시 방법에 따른 트래픽 채널 생성 횟수를 카운팅하기 위한 과정 중 하나를 보여주는 일실시예도이다.6 to 7 illustrate one example of a process for counting the number of traffic channel generations according to the embodiment of the present invention through the checker 30 and the analyzer 40.
무선단말장치(200)에서 특정 서버(300)로 데이터를 전송하는 일련의 과정을 도면 6과 같으며, 데이터의 전송이 없을 경우, 즉 dormant 상태로 변경되는 시간을 n초라고 가정하거나, 도먼트 타임이라고 가정할 수 있다.6 shows a series of processes for transmitting data from the wireless terminal device 200 to a specific server 300. If there is no data transmission, that is, the time to change to the dormant state is assumed to be n seconds, or dome. It can be assumed that it is time.
무선단말장치(200)에서 데이터 전송의 상태에 따라서 도 6과 같은 상황이 계속해서 반복되며, 역으로 생각하면 데이터 수신 간의 간격이 n초 이상이거나 도먼트 타임 이상이라면, 상기 분석부(40)는 데이터와 데이터 중간에 무선단말장치(200)에서 트래픽 채널을 생성하는 과정이 들어갔다고 판단하고, 트래픽 채널 생성 횟수를 1개씩 카운팅할 수 있다.According to the state of data transmission in the wireless terminal device 200, the situation as shown in FIG. 6 is repeated repeatedly. In contrast, if the interval between data reception is equal to or longer than n seconds or more than doment time, the analyzer 40 It may be determined that the process of generating a traffic channel in the wireless terminal device 200 between data and data is counted, and the number of traffic channel generations may be counted one by one.
예를들면, GGSN에서 캡쳐한 데이터는 TCP/IP 패킷으로 이들의 시간 간격은 알 수 있으며, 각각의 패킷에 대해서 이전 시간과의 간격이 n초 이상 또는 도먼트 타임 이상 벌어진다면 트래픽 채널이 생성이 되었다고 판단하며, 이를 전체 패킷에 대해서 적용하면 하나의 무선단말장치(200)의 통신을 위해서 몇 번의 트래픽 채널이 생성이 되었는지를 검출할 수 있다.For example, the data captured by GGSN are TCP / IP packets and their time intervals are known, and for each packet a traffic channel can be generated if the interval between the previous times is longer than n seconds or more than doment time. If it is determined that this is applied to the entire packet, it is possible to detect how many traffic channels are generated for communication of one wireless terminal device 200.
도 7을 참조하면, 상기 확인부(30)에서 각각의 패킷에 대해서 이전 패킷과의 간격이 n초 이상이거나 도먼트 타임 이상인지를 확인하고, 확인결과, 지정된 시간범위를 벗어나면, 분석부(40)에서 트래픽 채널이 생성된 횟수를 1증가 시키는 것을 볼 수 있다.Referring to FIG. 7, the identification unit 30 checks whether the interval between the previous packet is n seconds or more than the dormant time for each packet, and if it is out of the designated time range, the analysis unit ( In 40, it can be seen that the number of times the traffic channel is generated increases by one.
즉, 도 7에 따르면, (1), (2), (3)패킷이 이전 패킷과 n초 이상 또는 도먼트 타임 이상의 시간 간격으로 나타나며, 이 경우 3번의 트래픽 채널이 생성 및 해제되었다는 정보를 검출할 수 있게 된다.That is, according to FIG. 7, packets (1), (2), and (3) appear at a time interval of more than n seconds or more than doment time with the previous packet, and in this case, information indicating that three traffic channels have been created and released is detected. You can do it.
