FIG. 3 is a diagram showing a main configuration of a signal detection apparatus 100 according to an embodiment of the present invention.

In more detail, FIG. 3 shows a signal detection apparatus 100 connected to a communication network or a network through which a plurality of wireless terminal devices 200 and a plurality of servers 300 transmit and receive packets, And the following packet and data are interpreted in the same meaning), and then counts the number of times of traffic channel generation.

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 signal 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, Arranges the packets in the order of packet acquisition or capture time according to unique identification information of each wireless terminal device 200 and confirms whether the time interval between the sorted packets and the previous packet is n seconds or more, , Counts the number of times of traffic channel generation in the wireless terminal device (200) at each occurrence of the interval equal to or longer than n seconds, and then counts the number of times of traffic channel generation in the wireless terminal device The number of signals that occur during the creation and release of a traffic channel between a base station and a device on a communication network including one or more exchange stations is a and b A total number of signal generations in the wireless terminal device is detected by multiplying the sum of a and b by the counted number of traffic channel generations.

Here, the n seconds include a time required for automatically releasing the traffic channel after the generation of the traffic channel through the wireless terminal device 200 and the packet transmission / reception is not performed for a certain period of time and the time period determined by the policy of the communication company system . &Lt; / RTI >

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 signal 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, (50).

Here, the signal detecting apparatus 100 is shown as a single apparatus in the drawing for explaining the embodiment, but each of the constituent units may be configured separately from one or more apparatus 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 verification unit 30 according to the embodiment of the present invention determines whether the time interval with respect to the previous packet for each packet sorted through the preprocessing unit 20 is n seconds (for example, The analysis unit 40 according to the embodiment of the present invention performs a function of checking whether the packet transmission / reception time is longer than the time required to automatically release the traffic channel , And counts the number of times of traffic channel generation in the wireless terminal device 200 at each occurrence of the interval equal to or longer than n seconds, when the interval between the previous packet and the previous packet is more than n seconds.

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. [

The process of transmitting data from the wireless terminal device 200 to the specific server 300 is as shown in FIG. 6, assuming that the time to change to the dormant state is n seconds when there is no data transmission.

6 is continuously repeated according to the state of data transmission in the wireless terminal apparatus 200. Conversely, if the interval between data reception is n seconds or more, the analysis unit 40 determines The wireless terminal device 200 determines that the process of generating a traffic channel is entered, and counts the number of traffic channel generations by one.

For example, the data captured by the GGSN is a TCP / IP packet and their time interval is known. If the interval between the packet and the previous time is longer than n seconds, it is determined that the traffic channel is generated. It is possible to detect how many traffic channels have been generated for communication of one wireless terminal device 200 by applying to the entire packet.

Referring to FIG. 7, if the check unit 30 determines that the interval between the previous packet and the previous packet is n seconds or more, the analyzer 40 determines that the traffic channel The number of times of generation is increased by one.

That is, according to FIG. 7, the packets of (1), (2), and (3) appear at time intervals of n seconds or more with respect to the previous packet, and 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 detects the number of signals generated while the traffic channel between the wireless terminal device 200 and a device on the communication network (a device on a communication network including at least one base station and an exchange) The sum of the a and b is multiplied by the traffic channel generation count counted by the analysis unit 30 to detect the total number of signal generations in the wireless terminal apparatus 200 Thereby enabling monitoring of the number of signal transmissions in the wireless terminal device 200, which is one of the causes of overload of the mobile network.

The detecting unit 50 according to an embodiment of the present invention may be configured to detect whether or not the server of the packet transmission and reception server 300 of the packet collected or captured at the first time after the elapse of the time interval of n seconds or more, And detects the information of the server 300 that generated the first traffic channel in the wireless terminal device 200 by checking the address information of the wireless terminal device 300.

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 detecting unit 50 detects a server 300 of a packet transmission / reception server 300 of a packet to be collected or captured at a first time after a lapse of a time interval of n seconds or more, The first server 300 that has generated the first traffic channel detects the address information and detects the information of the first server 300 that generated the first traffic channel in the wireless terminal device 200. However, The server 300 of the packet transmission / reception server 300 of the packet to be collected or captured at the second time except for the first server 300 when the server 300 is confirmed to be irrelevant to the server 300 ) Address information to detect the information of the second server 300 that has generated the first traffic channel in the wireless terminal device 200.
