[Description of Fig. 1]

1 is a diagram schematically illustrating a mobile communication system equipped with a traffic control apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the mobile communication system includes wireless terminals 50-1 to 50-n, 51-1 to 51-n ', base stations 50 and 51, RNC 20, GSN 30, business computing ( The traffic control apparatus 10 according to an embodiment of the present invention may be connected to the GSN 30 of the core network to obtain data traffic information between the terminal connected to the wireless access network and the external network. In addition, the traffic control apparatus 10 may be connected to the RNC 20 of a wireless access network to transmit an AC Barring (Access Class Barring) request for traffic transmission control to the RNC 20, and is connected to the business computer 40. Data session blocking request for traffic transmission control can be made.

Base stations 50 and 51 are responsible for wireless communication with wireless terminals within a particular cell. In the example of FIG. 1, one base station 50 is responsible for wireless communication with wireless terminals 50-1 through 50-n located in cell A, and another base station 51 is a wireless terminal 51 located in cell B. -1 to 51-n '). Meanwhile, the cell in the present specification refers to a coverage area that can be controlled by one base station with respect to a radio resource used by the radio terminal. For example, a femto cell and a pico cell are used. , Micro cells, macro cells, mega cells, and the like.

Meanwhile, in the wireless terminal, the mobile communication terminal 11 may be a notebook, tablet PC, PDA (Personal Digital Assistant) equipped with a wireless modem, in addition to a cellular phone or a smart phone. Etc.) may be a computing device. The wireless terminals 50-1 to 50-n and 51-1 to 51-n 'may include at least one USIM that stores unique information of the user, and the USIM includes IMSI (International Mobile), which is a subscriber personal identification number. Subscriber Identity) information may be stored.

The RNC 20 is a radio network control station connected to the base stations 50 and 51 and the core network. The RNC 20 performs a radio resource control and a switching function for transferring data transmitted through the radio access network to an appropriate node. 50, 51) can be controlled. In particular, the RNC 20 may perform AC Barring processing on the wireless terminals 50-1 to 50-n and 51-1 to 51-n ′ connected to the base stations 50 and 51. AC barring is a mechanism for preventing access of a wireless terminal through information broadcast from the base station in order to prevent overload of the base station.

The GSN 30, which is one of the elements of the core network, supports the GPRS network of the external network and the mobile communication system such as SGSN (Support GRPS Serving Node) and the Internet, which serve to transmit data packets transmitted or received from the mobile terminal. It consists of a Gateway GPRS Support Node (GGSN) that acts as a connection. In the present embodiment, the GSN 30 may transmit the information about the packet transmitted from the wireless terminal to the external network or transmitted from the external network to the wireless terminal to the traffic control apparatus 10. The packet information may include information about the origin and destination of the packet, information about the size of the packet, and the like. The traffic control apparatus 10 may manage traffic information for each of a wireless terminal and a destination, a wireless terminal and a source, a cell and a destination, or a cell and a source by using the received packet information. For example, if any one of the wireless terminals (wireless terminals 50-1 to 50-n) located in cell A transmits a packet to any server 60 located on the Internet, the packet passes through the GSN to the Internet network. Since the GSN transmits the information about the packet to the traffic control apparatus 10, the traffic control apparatus 10 is transmitted to the wireless terminal or the server 60 that is the cell and the destination to which the wireless terminal belongs. Traffic information can be managed by updating the information of this packet with corresponding traffic information.

Meanwhile, the mobile communication system may further include a sales computer 40 for storing the service information and the security related information of the subscriber and controlling the mobile communication system.

In the above, the schematic configuration of the mobile communication system having the traffic control device 10 according to the present invention has been described. Hereinafter, the configuration of the traffic control apparatus 10 according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3A to 3B.

[Description of Fig. 2]

2, the traffic control apparatus 10 according to an embodiment of the present invention may include a communication unit 100, a control unit 110, and a database 120.

The communication unit 100 may receive packet information from the GSN 30 under the control of the control unit 110, and may transmit a control request to the RNC 20 or the business computer 40.

The database 120 may store, for example, traffic information and information of a cell to which the terminal belongs. 3A and 3B illustrate an example of a table of terminals belonging to a specific cell stored in a database according to the present embodiment, and a table of traffic information for each cell and a destination address. Unlike FIG. 3A, the table may store IMSI information of the terminal instead of the IP information of the terminal. That is, the information stored in this table may be anything as long as it can identify the terminal. The cell-wireless terminal table included in the database 120 shows the RNC, Home Location Register (HLR) or Visitor Location (VLR) when a new wireless terminal is connected to a base station or when an existing wireless terminal is handed over to another base station. It can be updated by the relevant information transmitted from the register.

In addition, the database according to the present embodiment may further include a table for traffic information for each cell and source address similar to that of FIG. 3B.

The controller 110 may receive the packet information through the communication unit 100, update the traffic information stored in the database, and determine which one of the traffic information satisfies a preset limit criterion. That is, when the controller 110 receives the packet information, the controller 110 determines which cell the wireless terminal transmitting the packet belongs to, and reads the traffic information corresponding to the cell and the destination address from the database 120. Thereafter, the traffic information may be updated to reflect the packet information in the read traffic information, and may be stored in the database 120 again. Thereafter, the controller 110 may determine whether the updated traffic information satisfies a preset limit criterion. Here, the limit criterion is a unit of traffic transmitted from a plurality of wireless terminals belonging to a specific cell to one server located in an external network or traffic transmitted from one server located in an external network to a plurality of wireless terminals belonging to a specific cell. The number of packets per hour may be set to exceed a preset threshold or the amount of data per unit time exceeds a preset threshold.

In addition, when the traffic information satisfies the preset threshold, the controller 110 controls the wireless terminal in the cell that satisfies the threshold to no longer transmit the traffic. Or a control request to the business computer 40. When the traffic that satisfies the threshold is outgoing traffic transmitted from a specific cell to an external network, an RNC (connected to a base station controlling the specific cell so that the wireless terminal included in the specific cell can be AC Barringed) 20) will send a control request.

Referring to FIGS. 3A and 3B as an example, when a threshold is set to transmit more than 6500 packets per second by traffic transmitted from a plurality of wireless terminals included in a specific cell to one server, the IP from cell A is set to IP. Since the traffic transmitted to the server of the external network whose address is 63.102.88.1 satisfies the above limit criteria, the control unit 110 has a radio having 182.176.43.2, 182.176.43.9, 182.176.43.71 and 182.176.43.72 included in cell A. The terminal will be AC Barring process.

On the other hand, if the traffic that meets the limit criteria is incoming traffic transmitted from a foreign network to a specific cell, the traffic transmitted to the specific cell is distributed and at least some of the packets included in the traffic are dropped. The control signal may be transmitted to the business computer 40 or the GSN 30 so as to be able to do so. Then, for example, the GSN 30 may distribute traffic transmitted to the specific cell in a manner that gives a different delay for each packet included in the traffic.

The traffic management apparatus and each component according to the present invention may include hardware resources and / or software necessary to implement the technical idea of the present invention, and necessarily mean one physical component or one device. It does not mean. That is, the traffic management apparatus may mean a logical combination of hardware and / or software provided to implement the technical idea of the present invention. If necessary, the traffic management apparatus may be installed in a device spaced apart from each other, And may be implemented as a set of logical structures for implementing the technical idea of the invention. Also, the traffic management apparatus may mean a set of configurations separately implemented for each function or role for implementing the technical idea of the present invention.

The wireless terminal of the AC barring process for a predetermined period (S460). In FIG. 4, the traffic control apparatus 10 transmits an AC Barring request to the RNC 20 (S450), and the received RNC 20 transmits an AC Barring request to the base station (S455). However, there may be an embodiment in which the traffic control device 10 transmits an AC Barring request directly to the base station ().

On the other hand, in the case of data session blocking, in order to block the data session of the GSN 30 set by the corresponding wireless terminal (that is, the plurality of wireless terminals which have transmitted the traffic satisfying the preset limit criteria) for a predetermined period. The traffic control apparatus 10 may make a data session blocking request (S470) to the business computer 40, and the business computer 40 may transmit a session block request (S475) to the GSN 30 again. Then, the GSN 30 blocks the data session of the terminal for a predetermined period, so that the terminal cannot transmit data for the predetermined period (S480). On the other hand, unlike FIG. 4, there may be an embodiment in which the traffic control device 10 makes a request for blocking a data session directly to the GSN 30 without going through the business calculation 40.

Can be delivered (S500).

Then, the traffic control apparatus 10 obtains the destination terminal to receive the packet and the source information of the packet from the packet information (S510). The source information of the packet may be an IP address, and the information of the destination terminal may be IP information or IMSI information of the wireless terminal, and identification information of other terminals.

The traffic control apparatus 10 may search the database 120 to identify information of a cell to which the wireless terminal to receive the packet belongs (S520). The traffic control apparatus 10 reads out traffic information mapped to the cell and the destination address of the packet from a database, and updates the traffic information by reflecting the packet information in the read traffic information (S530).

Thereafter, the traffic control apparatus 10 determines whether the traffic information satisfies a preset limit criterion (S540), and when satisfied, blocks the at least some of the packets included in the traffic in the GSN 30 or packets within the traffic. The control request is transmitted to the GSN 30 via the business computer 40 so as to delay the transmission of at least some of them (S550 and S555).
