FIG. 3 is a block diagram illustrating a main part of a traffic channel detecting apparatus 100 according to an embodiment of the present invention. Referring to FIG.

3 shows a detailed configuration of a traffic channel detecting apparatus 100 according to an embodiment of the present invention. Referring to FIG. 3, a traffic channel detecting apparatus 100 is connected to a communication network or a network through which a plurality of wireless terminal apparatuses 200 and a plurality of servers 300 transmit / And the following packet and data are interpreted in the same meaning) is collected or captured, and then the number of times of traffic channel generation is counted.

Each of the configurations shown in FIG. 3 is a configuration for explaining an embodiment of the present invention, and the technical features of the present invention are not limited only by the implementation method shown in FIG.

According to an embodiment of the present invention, the traffic channel detecting apparatus 100 collects or captures a plurality of packets transmitted and received between a plurality of wireless terminal apparatuses 200 and a plurality of servers 300 through a communication network, And arranges the received packets in the order of packet collection or capture time according to the unique identification information of each wireless terminal device 200. The time interval with respect to the previous packet for each sorted packet is a dormant time, After confirming that the time required for automatically releasing the traffic channel is longer than the time required to transmit / receive the packet for a certain period of time after the traffic channel checked through the system, it is checked that the interval between the previous packet and the previous packet is longer than the dormant time If it is determined that the number of traffic channel generation times in the wireless terminal device 200 is one Counting.

Here, the dormant time may be a fast dormant time for releasing a traffic channel directly from the wireless terminal device and a network control fast dormant time for releasing a traffic channel of the wireless terminal device in a device of a communication network, .

The unique identification information of the wireless terminal device 200 may include at least one of an IP (Internet Protocol), a port, a telephone number, and a MAC of the wireless terminal device 200.

Referring to FIG. 3, a traffic channel detecting apparatus 100 according to an embodiment of the present invention includes a collecting unit 10, a preprocessing unit 20, an identifying unit 30, an analyzing unit 40, And a detection unit 50.

Here, although the traffic channel detecting apparatus 100 is shown as a single apparatus in the drawing for explaining the embodiment, each of the constituent units may be configured separately from one or more apparatuses or servers.

Referring to FIG. 3, the collecting unit 10 collects or captures a plurality of packets transmitted and received between a plurality of wireless terminal devices 200 and a plurality of servers 300 through a communication network.

According to an embodiment of the present invention, when the wireless terminal device 200 communicates with the server 300 (game, web, chat, YouTube, etc.), the packet generated in the wireless terminal device 200 is basically transmitted to the GGSN IP protocol through the gateway GPRS Support Node and transmitted to the corresponding server 300. The packet is transmitted to the server 300 without causing a problem in communication between the wireless terminal 200 and the server 300. [ It should be analyzed that the collecting unit 10 copies the packet, and then transmits the copied packet to the preprocessing unit 20.

Referring to FIG. 4, which is an embodiment showing a process of generating and releasing a traffic channel in a conventional wireless terminal device 200, the wireless terminal device 200 transmits a Cell_DCH (in case of 3G) or a Cell_DCH in a basic state (idle) ECM Connected (in the case of 4G) state. A change in status means that a traffic channel has been created through communication over a signal with a device on the network (a device on the network or a core network that includes one or more base stations and an exchange) it means.

In a state where a traffic channel is generated, user data can be exchanged between the wireless terminal device 200 and a device on the communication network without any separate signal communication. When the generated traffic channel does not move for a predetermined time, (200) is automatically changed to the idle state, which is referred to as a dormant state.

There are two methods of entering the dormant state. One is FD (Fast Dormancy) in which the wireless terminal device 200 directly changes to the dormant state, and the other is the FD (Fast Dormancy) in which the wireless terminal device 200 enters the dormant state in the core network. There is an NCFD (Network Controlled Fast Dormancy) scheme that instructs.

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 / reception state, and when the data is not moved for a predetermined time after the data transmission, And the traffic channels are repeatedly generated and released. The traffic channel creation and cancellation process is a main cause of the load on the wireless network. When it is detected that the number of traffic channels is generated , And can be used as basic data to solve the load problem on the wireless network.

The preprocessing unit 20 according to the present invention plays a role of arranging the packets collected or captured by the collecting unit 10 in the order of packet collection or capture time according to unique identification information of each wireless terminal device 200.

A packet exchanged between the wireless terminal device 200 and the server 300 in the communication network is a packet between the specific wireless terminal device 200 and the specific server In order to identify the traffic channel formed between the wireless terminals 200 and 300, the packets collected or captured by the collecting unit 10 must be classified according to the unique identification information of each wireless terminal 200. In the pre-processing unit 20, The packets collected or captured by the collecting unit 10 are classified according to unique identification information (for example, IP) of the wireless terminal 200, and sorted and sorted in the order of packet collection or capture time.

5 is an embodiment showing one of the preprocessing processes according to an embodiment of the invention.

As shown in FIG. 5, the preprocessor 20 sorts a plurality of packets collected by the collecting unit 10 according to cooperative identification information of the wireless terminal 200, and arranges them in the order of packet collection or capture time.

The confirmation unit 30 according to the embodiment of the present invention determines whether the time required for automatically releasing a traffic channel due to a dormant time occurring due to a dormant time occurring due to no transmission / And checks whether the time interval between the packet and the previous packet is equal to or greater than the dormancy time for each of the packets sorted through the preprocessing unit 20. In the embodiment of the present invention, If the time interval between the previous packet and the previous packet is more than the dormant time as a result of the checking by the checking unit 30, And counts the number of generations one by one.

To accurately determine whether a traffic channel has occurred, it is necessary to know the dormant time accurately. Since the time for changing to the dormant mode by FD or NCFD differs for each communication company, terminal, and region, In this case, the confirmation time of the dormant time through the confirmation unit 30 is determined by comparing the previous packet with each packet sorted by the preprocessing unit 20 in the confirmation unit 30 Regardless of whether or not the time interval is greater than or equal to the dormant time.

6 to 7 are diagrams illustrating an example of a process for counting traffic channel generation counts according to an embodiment of the present invention through the verification unit 30 and the analysis unit 40. [

6 shows a series of processes for transmitting data from the wireless terminal device 200 to a specific server 300. It is assumed that the time when the data is not transferred, that is, the time to change to the dormant state is a dormant time.

6 is continuously repeated according to the state of data transmission in the wireless terminal device 200. Conversely, if the interval between data reception is more than dormant time, The wireless terminal device 200 determines that the process of generating a traffic channel is entered and counts the number of traffic channel generation by one.

For example, the data captured by the GGSN can be known as a TCP / IP packet, and if the gap between the previous time and the previous time is greater than the dormant time, it is determined that the traffic channel is generated. By applying this to all packets, it is possible to detect how many traffic channels have been generated for communication of one wireless terminal device 200.

Referring to FIG. 7, if the check unit 30 determines that the interval between the packet and the previous packet is equal to or greater than the dormancy time, and the analyzing unit 40 is out of the designated time range, It can be seen that the number of times the channel is generated is increased by one.

That is, according to FIG. 7, the packets (1), (2), and (3) are displayed at time intervals equal to or longer than the previous packet and dormant time. In this case, information indicating that three traffic channels are generated and released can be detected .

The detection unit 50 according to the embodiment of the present invention may be configured to detect the presence or absence of a packet of the packet collected or captured at the first time after the elapse of the dormancy- 300) address information to detect information of the server 300 that generated the first traffic channel in the wireless terminal device 200.

That is, the detecting unit 50 confirms the information of the specific server 300 to which the wireless terminal 200, which is the object of the traffic channel generation, And to provide basic data for controlling traffic channel generation between the terminal devices 200.

According to the present invention, the detection unit 50 detects the presence or absence of the server 300 of the packet transmission / reception server 300 of the packet collected or captured at the first time after the elapse of the dormancy time interval exceeded by the confirmation unit 30 The first server 300 that generates the first traffic channel detects the first server 300 information that has generated the first traffic channel in the wireless terminal device 200 by checking the address information, The server 300 of the packet transmission / reception server 300 of the packet collected or captured at the second time except for the first server 300 when the server 300 is identified as a server 300 irrelevant to the wireless network load 300) address information to detect information of the second server 300 that has generated the first traffic channel in the wireless terminal device 200.

FIG. 8 is a diagram illustrating a process of detecting information on a server 300 that causes traffic channel generation according to an embodiment of the present invention.

8, assuming that data in which a specific wireless terminal device 200 communicates with a plurality of servers 300 exists and a, b, c, d, etc. in the box are specific servers 300 , If a total of five traffic channels are generated as shown in FIG. 8, a server 300 generates a total of three traffic channels, and the b server 300 generates a total of two traffic channels.
