The adaptive non-real time traffic control system includes only the terminal 110, the traffic control application 112, the network 120, the policy providing device 130, the content providing device 140 and the billing gateway 150 However, it will be appreciated that those skilled in the art will appreciate that variations and modifications may be made without departing from the essential characteristics of the present invention, It will be possible to variously modify and adapt the constituent elements included in the control system. Here, traffic refers to the amount of data that flows within a certain period of time on the transmission path of the network 120.

The terminal 110 is a terminal capable of transmitting and receiving various data via the network 120 according to a key operation or a command of the user. The terminal 110 may be a tablet PC, a laptop, a personal computer Computer, a smart phone, a personal digital assistant (PDA), and a mobile communication terminal. In addition, the terminal 110 may be a cloud computing terminal that supports cloud computing that can use services such as data reading, writing, storing, network, and content usage through the network 120.

That is, the terminal 110 is a terminal that performs voice or data communication using the network 120 and includes a memory for storing a program or a protocol for communicating with the content providing apparatus 140 via the network 120, And a microprocessor for executing and controlling the program. That is, the terminal 110 may be any terminal as long as it can perform server-client communication with the content providing apparatus 140, and it is a broad concept including all communication computing devices such as a notebook computer, a mobile communication terminal, and a PDA. The terminal 110 includes a plurality of communication modules and performs voice or data communication through the path networks 122, 124, 126, and 128, which are used as paths of non-real-time traffic in the network 120 And may communicate with the content providing device 140 via the route network 122, 124, 126 and 128. [ The terminal 110 manages data to store contents in the terminal 110 or to send traffic of the terminal 110 to the contents providing apparatus 140 for traffic processing. Although the terminal 110 is described as being implemented as a separate apparatus from the policy providing apparatus 130 in the present embodiment, the terminal 110 includes all of the policy providing apparatus 130 (Stand Alone) device.

The terminal 110 according to the present embodiment can implement the adaptive non-real time traffic control by loading the traffic control application 112. [ That is, the terminal 110 may drive the traffic control application 112 by a user's operation or command, and may control the adaptive non-real time traffic control through the traffic control application 112. More specifically, the traffic control application 112 refers to an application installed after being downloaded through an application store, if the terminal 110 is a smart phone, (Feature Phone) refers to an application running on a VM (Virtual Machine) downloaded through a communication company server.

The traffic control application 112 may be installed in the terminal 110 according to the embodiment of the present invention. The terminal 110 may be implemented in a state in which the traffic control application 112 is mounted in an embedded form , An OS (Operating System) mounted in the terminal 110, or installed in an OS in the terminal 110 by a user's operation or command. The traffic control application 112 loaded on the terminal 110 in the manner described above is linked to the basic application (e.g., a text sending application, a voice call sending / receiving application, a data sending / receiving application, a messenger application, etc.) However, the present invention is not limited thereto, and can be implemented to operate as an independent function without interlocking with the basic application.

Hereinafter, an operation of adaptively and non-real-time traffic control of the terminal 110 according to the present embodiment will be described. The terminal 110 generates a non-real-time traffic request signal based on an input user operation or command. Here, the non-real-time traffic request signal is a kind of traffic request signal. When the user inputs a command for requesting specific contents by operating the terminal 110, the terminal 110 transmits the contents to the contents providing apparatus 140 The terminal 110 controls the traffic according to the network state of the path network 122, 124, 126, and 128, so that when the network state is congested, the non-real- Traffic request signal. Meanwhile, the same concept can be applied to the non-real-time traffic response signal corresponding to the non-real-time traffic request signal.

The terminal 110 transmits a policy request signal including data related information to the policy providing apparatus 130, receives a policy response signal in response to the policy request signal, and transmits the policy response signal to the path networks 122, 124, 126 < / RTI > and 128). Here, the data-related information includes data usage and related information, and includes Charging Data Record (CDR) start information, CDR interim information, and CDR stop information. That is, the data-related information includes the CDR start information when the initial data download is started for the specific content, and the CDR interleave information is included during the data download for the content. When the data download for the content is completed CDR stop information. The data-related information is information including at least one of the number of data packets and the data packet usage information for each number of data packets.

The terminal 110 downloads a non-real-time traffic response signal corresponding to the non-real-time traffic request signal from the content providing apparatus 140 via the path network 122, 124, 126 and 128, Uploads the previously stored contents to the content providing device 140, and controls downloading or uploading (traffic) based on the network status upon downloading or uploading.

A process of recognizing the network status of the path networks 122, 124, 126, and 128 to which the terminal 110 communicates will be described. The terminal 110 recognizes the network state as one of a congestion state, a normal state, and a smooth state based on the propagation environment signals received from the path networks 122, 124, 126, and 128. [ At this time, the terminal 110 recognizes the network state by comparing at least one parameter among the parameters included in the propagation environment signal, Rx, Tx, Ec / Io, RSSI, In addition, the terminal 110 compares the parameter with the network state threshold, and recognizes the network state as a congestion state when the parameter exceeds the network state threshold. Also, the terminal 110 compares the parameter with the network state threshold, and recognizes the network state as smooth if the parameter is below the network state threshold. In addition, the terminal 110 compares the parameter with the network state threshold, and recognizes the network state as a normal state when the parameter is included in the tolerance range of the network state threshold.

Meanwhile, the terminal 110 can determine the order of the generated traffic request signal when transmitting the generated traffic request signal to the content providing apparatus 140. Specifically, it is as follows. The terminal 110 determines the transmission order of the non-real-time traffic request signal transmitted to the content providing apparatus 140 according to the input operation of the user or the order of the command or the priority information based on the type of the content. Also, the terminal 110 transmits a non-real-time traffic request signal to the contents providing apparatus 140 based on the determined transmission order.

Here, the policy response signal received by the terminal 110 from the policy providing apparatus 130 is a signal including at least one of policy request period information, a threshold value, and priority information according to the network status. At this time, the threshold value is information including respective threshold values for a plurality of parameters related to traffic control. In addition, the threshold value may include at least one of the number of terminals assigned to the transmitter 210, 220 in the path network 122, 124, 126, and 128, the traffic transmission status of each terminal, It is a value that is set adaptively according to information. In addition, the threshold value has a value that limits the number of terminals allocated for each transmitter in the path network (any one of 122, 124, 126, and 128) to within a predetermined range. On the other hand, the priority information has priority values based on the values set to transmit the traffic preferentially at the shortest time (the time at which the call is generated the least during the day) or the type of the route network (any of 122, 124, 126 and 128) . That is, the traffic parameters may include Rx, Tx, Ec / Io, rate, number of assigned terminals, and the like.

Hereinafter, a process in which the terminal 110 recognizes the network state and adaptively controls the non-real time traffic will be described in detail. The terminal 110 compares the transmission rate with the threshold value included in the policy response signal at the time of downloading or uploading, and when the transmission rate is less than the threshold value, the terminal 110 recognizes that the network status is congested and stops download upload (traffic). That is, when the key quality indicators of Rx and Tx among the parameters related to the traffic control included in the policy response signal are less than the threshold value, the terminal 110 recognizes that the network status is congested and stops downloading or uploading (traffic) . The terminal 110 may also determine that the distance between the location of the terminal assigned to the transmitter 210, 220 in the path network 122, 124, 126 and 128 and the transmitter 210, 220 exceeds a predetermined distance It stops downloading or uploading (traffic) for resource efficiency of the path networks 122, 124, 126 and 128. [ In addition, the terminal 110 stops downloading or uploading (traffic) when the terminal battery status is below the threshold value or when the terminal temperature exceeds the threshold value.

Hereinafter, a process of retrying non-real time traffic of the terminal 110 will be described. The terminal 110 operates to repeat the download or upload (traffic) retry according to the policy response signal. That is, the terminal 110 performs a download or upload (traffic) retry when a preset timer time elapses. In addition, the terminal 110 performs a download or upload (traffic) retry if the path network 122, 124, 126 and 128 is changed to another network. In addition, the terminal 110 performs a download or upload (traffic) retry when a new non-real-time traffic request signal is received.

Hereinafter, a driving method of the traffic control application 112 will be described.

In addition, the traffic control application 112 may operate in conjunction with pre-installed applications in the terminal 110.

The traffic control application 112 may also be installed within the terminal 110 to determine whether the traffic control application 112 is to perform the traffic control application 112. For example, And the like), and manages the adaptive data traffic based on the recognized network state.

To describe this operation of the traffic control application 112 more specifically, the traffic control application 112 generates a non-real-time traffic request signal by an operation or an instruction of the inputted user. The traffic control application 112 transmits a policy request signal including data related information to the policy providing device 130, receives a policy response signal corresponding to the policy request signal, and transmits the policy response signal to the path networks 122, 124, 126, and 128). The traffic control application 112 downloads a non-real-time traffic response signal corresponding to the non-real-time traffic request signal from the content providing device 140 via the path network 122, 124, 126 and 128, ) To the content providing apparatus 140, and controls downloading or uploading (traffic) based on the network status upon downloading or uploading the content.

The network 120 may include a cloud computing network that can be coupled to the content providing apparatus 140 to store computing resources such as hardware and software and to provide the computing resources required by the client to the terminal 110 can do. Here, cloud computing refers to a computer environment in which information is permanently stored on a server on the Internet and temporarily stored in a client terminal such as a desktop, a tablet computer, a notebook, a netbook, or a smart phone. Cloud computing, Refers to a computer environment access network that stores information on a server on the Internet and makes the information available anytime and anywhere through various IT devices. The network 120 will be described in detail with reference to FIG. Here, the network 120 includes an accounting gateway 150.

The policy providing device 130 recognizes the network status of each terminal assigned to the path networks 122, 124, 126, and 128, and determines and manages policies related to data traffic based on the detected network status Function. That is, when the policy providing apparatus 130 receives the policy request signal from the terminal 110, the policy providing apparatus 130 interlocks with the terminal 110 via the network 120. When the policy providing apparatus 130 receives the policy request signal from the terminal 110, Generates a policy response signal corresponding to the request signal, and transmits the policy response signal to the terminal 110. The policy providing apparatus 130 may use a 3G PCRF (Policy Charging and Rules Function) 218 or a 4G PCRF 230.

Hereinafter, the process of the policy providing apparatus 130 recognizing the path networks 122, 124, 126, and 128 will be described. The policy providing apparatus 130 recognizes the network state as one of a congestion state, a normal state, and a smooth state based on a propagation environment signal received from the path network 122, 124, 126, and 128. [ In other words, the policy providing apparatus 130 transmits at least one parameter among the parameters Rx, Tx, Ec / Io, RSSI (Received Signal Strength Indication), transmission rate, Thereby recognizing the network state. At this time, the policy providing device 130 compares the parameter with the network state threshold, and recognizes the network state as a congestion state when the parameter exceeds the network state threshold. In addition, the policy providing device 130 compares the parameter with the network state threshold, and recognizes the network state as smooth if the parameter is less than the network state threshold. In addition, the policy providing device 130 compares the parameter with the network state threshold, and recognizes the network state as a normal state when the parameter is included in the error tolerance of the network state threshold.

Hereinafter, a process of generating the policy response signal corresponding to the policy request signal received from the terminal 110 will be described. The policy providing device 130 checks the network status to generate a policy response signal, and generates a policy response signal including at least one of policy request period information, a threshold value, and priority information according to the network status. At this time, the threshold value is information including respective threshold values for a plurality of parameters related to traffic control. That is, the threshold value may be set to be equal to or greater than at least one of the number of terminals assigned to the transmitter 210, 220 in the path network 122, 124, 126 and 128, the traffic transmission state of each terminal, It is a value that is set adaptively according to information. In addition, the threshold value has a value that limits the number of terminals allocated for each transmitter in the path network (any one of 122, 124, 126, and 128) to within a predetermined range. On the other hand, the priority information has a priority value based on the type of the route network (any one of 122, 124, 126, and 128) or a value set to transmit traffic at a minimum at a minimum. The policy providing apparatus 130 periodically transmits the policy response signal to the terminal 110.

The content providing apparatus 140 is a kind of server that performs content storage and management for transmitting or receiving data traffic of the terminal 110.

That is, the IP (Internet Protocol) of the policy providing apparatus 130 can be checked through the module implemented in software (S / W) at the input terminal of the billing gateway 150, and the device transmitting the CDR can be identified. For example, the serving gateway (Serving G / W) IP may be seen on the charging field. Meanwhile, a hardware card (for example, a DAG card as an Ethernet network monitoring card) that receives actual data, which is a module implemented in hardware (H / W), at the input terminal of the charging gateway 150 can be separately accommodated . If you remove these hardware cards, you can physically act as a single device, but actually two devices. That is, the data processing route in the charging gateway 150 is divided into two. In addition, the billing gateway 150 transmits billing data to an external device in a billing domain. In this case, since the billing domain can manage a plurality of directories by dividing a single directory, A directory for billing data can be separately generated and managed. At this time, the existing packet can be managed by the existing packet directory.

7 is an exemplary diagram illustrating a traffic control method according to the present embodiment.

The traffic control application 112 is installed in the terminal 110 to recognize the status of the path network 122, 124, 126, and 128 with which the terminal 110 is communicating, It is a kind of program that manages data traffic. The policy providing device 130 recognizes the network status of each terminal assigned to the path networks 122, 124, 126, and 128, and determines and manages policies related to data traffic based on the detected network status Function. The content providing apparatus 140 is a kind of server that performs content storage and management for transmitting or receiving data traffic of the terminal 110. The traffic processing module refers to a communication processing unit provided in the terminal 110. The traffic processing module shown in FIG. 7 is a kind of communication processing module included in the terminal 110, and stores the contents received from the contents providing apparatus 140 or transmits the data traffic stored in the terminal 110 to the contents providing apparatus 140).

7 shows that a non-real-time traffic transmission request signal is generated according to the user's selection, operation, or user type input from the terminal 110. [ That is, the terminal 110 generates a non-real-time traffic request signal based on an input user operation or command.

7, the generated non-real-time traffic transmission request signal is managed by the traffic control application 112 installed in the terminal 110, and a traffic transmission request Order adjustment. That is, the terminal 110 can determine the order of the generated traffic request signal when transmitting the generated traffic request signal to the content providing apparatus 140. In other words, the terminal 110 determines the transmission order of the non-real-time traffic request signal transmitted to the content providing apparatus 140 according to the input operation of the user or the order of the command or the priority information based on the type of the content. Also, the terminal 110 transmits a non-real-time traffic request signal to the contents providing apparatus 140 based on the determined transmission order.

The '③' shown in FIG. 7 indicates that the terminal 110 inquires about the traffic transmission to the policy providing apparatus 130. The policy providing apparatus 130 then determines the status of the terminal 110 and returns a policy request period and a traffic control related threshold value. That is, the terminal 110 transmits a policy request signal to the policy providing apparatus 130 and receives a policy response signal corresponding to the policy request signal. Here, the policy response signal received by the terminal 110 from the policy providing apparatus 130 is a signal including at least one of policy request period information, a threshold value, and priority information according to the network status.

(A) The policy providing device 130 transmits a threshold value for a plurality of parameters for determining traffic transmission control in order to determine whether or not the network is in a network state. That is, the threshold value is information including respective threshold values for a plurality of parameters associated with traffic control.

The threshold value is adaptively adjusted according to the number of terminals located in the transmitters 210 and 220, the traffic transmission state of the terminal, the transmission request time of the terminal, and the like (e.g., If the request time is older than the request time, the threshold value is lower than that of the shorter request time. That is, the threshold value may be set to be equal to or greater than at least one of the number of terminals assigned to the transmitter 210, 220 in the path network 122, 124, 126 and 128, the traffic transmission state of each terminal, It is a value that is set adaptively according to information.

The policy providing apparatus 130 manages the number of traffic transmission terminals per base station to prevent unnecessary congestion. That is, the threshold value has a value that limits the number of terminals allocated for each transmitter in the path network (any one of 122, 124, 126, and 128) to within a predetermined range.

(D) The policy providing device 130 has time (priority transmission at the shortest time) and network type (priority transmission, for example, Wi-Fi network). That is, the priority information has a priority value based on the type of the route network (any one of 122, 124, 126, and 128) or a value set to transmit the traffic with priority at the minimum.

The '④' shown in FIG. 7 indicates a non-real-time traffic request URL (Uniform Resource Locator) and a data transmission request and transmission to the contents providing apparatus 140. That is, the terminal 110 transmits a non-real-time traffic request signal to the content providing apparatus 140 corresponding to the URL.

In the case of download, '⑤' shown in FIG. 7 is requested to download from the content providing device 140 and stored in a storage space according to the type of the content. When the content is uploaded, the content is requested to be uploaded to the content providing device 140, And indicates transmission to the content providing apparatus 140. That is, the terminal 110 downloads the non-real-time traffic response signal corresponding to the non-real-time traffic request signal from the content providing apparatus 140 via the path network 122, 124, 126, or 128, To the content providing apparatus 140. The content providing apparatus 140 receives the content, At this time, when the terminal 110 downloads the non-real-time traffic response signal from the content providing device 140, the terminal 110 downloads the non-real-time traffic response signal to the preset storage area according to the data type of the non-real-

The '⑥' shown in FIG. 7 indicates the determination of whether or not the traffic transmission is controlled by recognizing the network state during the traffic transmission of the terminal. That is, the terminal 110 recognizes the network status of the path networks 122, 124, 126, and 128 based on the policy response signal, and determines whether or not to control the traffic based on the network status that is recognized at the time of downloading or uploading , And controls downloading or uploading (traffic) based on the determined traffic control.

If the current transmission rate is lower than the threshold value, it is determined that the network status is congested and the traffic transmission is stopped (for example, threshold value = 200 kbps, transmission rate of current download and upload is less than 200 kbp If the network status is not good). That is, the terminal 110 compares the transmission rate with the threshold value included in the policy response signal at the time of downloading or uploading, and if the transmission rate is less than the threshold value, the terminal 110 recognizes that the network state is congested and stops download upload (traffic).

If the main quality indicator of the RF layer and physical layer for Rx and Tx of the terminal 110 is lower than the threshold value, it is determined that the network state is bad and the traffic transmission is stopped (e.g., when the Ec / Io value is low, If the wireless state is not good, and the Tx headroom value is low, the wireless state of the upload is bad. That is, if the key quality indicators of Rx and Tx among the parameters related to the traffic control included in the policy response signal are less than the threshold value, the terminal 110 recognizes that the network state is congested and stops downloading or uploading (traffic) .

If it is relatively far from the transmitters 210 and 220 according to the position of the terminal 110, the transmission of traffic for resource efficiency of the network is stopped (for example, the level of the Modulation Coding Scheme (MCS) If it is determined that the transmitters 210 and 220 are far from the terminal 110, the network status is determined to be bad). That is, if the distance between the position of the terminal assigned to the transmitter 210, 220 in the path network 122, 124, 126, and 128 and the transmitter 210, 220 exceeds a predetermined distance It stops downloading or uploading (traffic) for resource efficiency of the path networks 122, 124, 126 and 128. [

(For example, when the battery state is lower than the threshold value, when the temperature of the terminal 110 is high, the transmission is stopped). That is, the terminal 110 stops downloading or uploading (traffic) when the terminal battery status is less than the threshold value or when the terminal temperature exceeds the threshold value.

7 shows transmission of network control information to the policy providing apparatus 130 according to a threshold value and a policy query period transmitted by the policy providing apparatus 130 according to the network status. That is, the terminal 110 transmits a policy request signal to the policy providing apparatus 130 according to the policy request period information included in the policy response signal.

Thereafter, the policy providing apparatus 130 performs a traffic transmission retry according to the transmitted policy (policy response signal) in step (8), and repeats the processes of (3) to (7). That is, the process of retrying the non-real-time traffic of the terminal 110 will be described. The terminal 110 operates to repeat the download or upload (traffic) retry according to the policy response signal.

(A) Retry after Timer: Retry transmission of a traffic after a specific waiting time (transmitted by the policy providing device 130) after stopping the traffic transmission. That is, the terminal 110 performs a download or upload (traffic) retry when the preset timer expires.

B) Retry in accordance with network modem change: Retries when changing the network modem to the wireless LAN network 126, the 3G network 122, the 4G network 124, and the like. That is, the terminal 110 also performs a download or upload (traffic) retry when the path network 122, 124, 126 and 128 is changed to another network.

Ⓒ When a new non-real time traffic transmission is requested, retry: Retry if user's selection / operation or user type is added. That is, the terminal 110 performs a download or upload (traffic) retry when a new non-real-time traffic request signal is received.
