Various modifications and variations to the components included in the control system may be applicable. 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 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 adaptive non-real-time traffic control by 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. In this case, the terminal 110 generates a non-real-time traffic request signal including charging identification information. 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. In addition, the billing identification information may be in the form of an information capsule encapsulating non-real time traffic identification information or real time traffic identification information. The terminal 110 transmits a policy request signal to the policy providing device 130, receives a policy response signal in response to the policy request signal, and selects one of the path networks 122, 124, 126, and 128 based on the policy response signal. Recognize the network status of one).

The terminal 110 downloads the 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, or 128, or in the terminal 110. While pre-stored content is uploaded to the content providing device 140, the download or upload (traffic) is controlled based on the network state when 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 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.

Ⓑ At this time, the threshold is adaptively adjusted according to the number of terminals located in the transmitters 210 and 220, the traffic transmission status of the terminal, the transmission request time of the terminal, etc. (for example, the threshold is transmitted by the terminals located in the base station). If the request time is old based on the request time, the threshold value is lower than that of the terminal having a short 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.
