The cloud connection device control system according to the embodiment of the present invention may be configured such that the access device control server 300 operating on virtualization basis receives a call generated through the access device 200 supporting the connection of the communication network 1000 to the terminal 100 Processes traffic, authentication, and billing, and controls the traffic of the terminal 100 connected to the access device 200.

Referring to FIG. 1, components of the cloud connection device control system of the present invention will be schematically described. The terminal 100 is connected to any one of the connection devices 200, Refers to a user apparatus that is connected to the communication network 1000 through the connected connection apparatus 200 and is capable of transmitting and receiving various data.

Herein, the terminal 100 may search for one or more access devices 200 located within a predetermined radius in an active or passive manner according to the IEEE 802.11 protocol, and perform a procedure for performing a connection with the discovered access device 200 have. When the connection with any one of the access devices 200 is completed, the terminal 100 can be connected to the communication network 1000, that is, a core network (not shown) And various kinds of information can be transmitted and received.

The connection device 200 refers to a device that supports connection of the communication network 1000 of the terminal 100 according to the embodiment of the present invention. For example, an access point may correspond to the connection device 200 of the present invention. However, the present invention is not limited thereto, and any device capable of supporting the connection of the communication network 1000 of the terminal 100 can operate as the connection device 200 of the present invention.

Particularly, the connection device 200 according to the embodiment of the present invention can constitute a site covering at least a certain range. Here, a site may be a point having the same logical characteristics as a company or a school, and may mean a range of a certain size, such as within a radius of 100 m. One site may preferably be composed of a plurality of connection devices 200.

In the prior art, a connection controller, which is a control device for processing various messages generated in connection with connection to the connection device 200 of the terminal 100, is allocated for each site, and one or more access devices 200 located in the site It had to be physically connected. For example, if there are 100 sites, there would also be a need for 100 connection controllers to control the access device 200 in each site. In addition, the number of connection devices 200 constituting the first site and the second site may be different from each other. The construction of the control device considering the characteristics of the site including the number of different connection devices 200 There is a problem in that it is impossible to organically control the apparatus according to the number of the receiving and connecting apparatuses 200. [

However, in the cloud connection device control system according to the embodiment of the present invention, the connection device control server 300 generates a connection controller which is a control device for processing various signaling messages generated through the connection device 200 by using the virtualization technology And it is possible to control traffic to the terminal 100 together with processing of various signaling messages generated through the access device 200. [

The access point control server 300 supports the process of creating, changing and deleting access controllers for processing various messages generated through the access device 200 in the site for each site by using virtualization technology as described above, And supports the entire process of processing various messages generated through the device 200 by the connection controller. That is, various messages generated according to a procedure such as call processing and authentication for accessing the communication network 1000 of the terminal 100 may be processed through a connection controller implemented in a virtualization technology. In addition, it can perform various functions for billing, such as statistical processing on data packets generated in association with the terminal 100.

At this time, the messages transmitted and received between the access controllers 200 and the access controllers in the access point control server 300, which are allocated in advance to the sites constituted by the access points 200, are transmitted and received according to a predetermined protocol. Here, the predetermined protocol means a protocol defined in advance between the access device 200 and the access point control server 300 according to the embodiment of the present invention, and the message at this time is transmitted to the access point control server 300 And the IP address information of the access controller allocated to the access device 200. The term " tunneling message " In other words, the message transmitted / received between the access point 200 and the access point 200 is a general message compliant with the TCP / IP protocol, while the message transmitted / received between the access point 200 and the access point 200 is predefined Refers to a tunneling message in which a tunneling header is added to a message transmitted / received between the AT 100 and the access point 200 according to the UDP protocol. The tunneling header at this time includes the port information (for example, 2233) corresponding to the access point control server 300 and the IP address information of the access controller 200 allocated to the access point 200, A virtual tunneling period (referred to as an R6 tunneling period in the present invention) may be formed so that a message generated through the tunneling period can be transmitted to a corresponding access controller of the access point control server 300. [

In particular, the access point control server 300 according to the embodiment of the present invention can perform a traffic control function for the terminal 100 as described above. To this end, the access point control server 300 calculates the effective traffic amount, and can control the traffic of the terminal 100 connected to the access device 200 allocated to the access controller according to the effective traffic amount.

At this time, the access point control server 300 of the present invention includes a communication apparatus that can operate through a separate operating system (OS). The communication apparatus at this time calculates the effective traffic amount of the terminal 100 , And control traffic of the terminal 100 according to the calculated effective traffic amount. In other words, the connection controller of the access point control server 300 can process various messages generated in connection with call processing, authentication, billing, etc. between the access points 200, and the communication device of the access point control server 300 And to control traffic to the terminal 100. A configuration in which the access point control server 300 calculates the effective traffic through the communication device and controls the traffic of the terminal 100 using the calculated effective traffic will be described later.

In addition, the access point control server 300 of the present invention creates and registers a connection controller in cooperation with the integrated management server 400, and provides information on the access point 200 located in the site to the access controller in advance Registration process can be performed.

Here, the integrated management server 400 is a component supporting the overall management process for the access point control server 300 according to the embodiment of the present invention. In particular, the integrated management server 400 according to an exemplary embodiment of the present invention generates a connection controller for a site composed of a plurality of access devices 200 in accordance with a virtualization scheme in consideration of available resources of the access point control server 300 . Then, information on the connection device 200 constituting the site covered by the connection controller is stored and registered in response to the generated connection controller. For example, if there are 50 access devices 200 in one site, the integrated management server 400 allocates resources in the access point control server 300 to accommodate 50 access devices 200, You can create a controller. By providing information on the 50 access devices 200 to the access controller and registering them, the access controller 200 can support the processing of messages generated between the registered access devices 200 and traffic control processing. For example, if there are 100 access devices 200 in one site, the integrated management server 400 allocates resources in the access point control server 300 to accommodate 100 access devices 200 A connection controller is created and the connection device 200 is registered.

In addition, the integrated management server 400 according to the embodiment of the present invention can support the approach of the administrator managing the cloud access point device control system of the present invention. That is, the administrator can input a control command for controlling various configurations including the access device 200 through the integrated management server 400. [ For example, the administrator may input a control command for setting a traffic volume limitation function for traffic control of the terminal 100 through the integrated management server 400. [

In addition, the integrated management server 400 of the present invention can send and receive information according to the TCP / IP protocol with the access point control server 300. The integrated management server 400 and the access point control server 300 generate a tunneling interval according to the designated protocol and send and receive messages between the access point 200 and the access point control server 300. The integrated management server 400 and the access point control server 300 transmit / And transmits and receives information according to the information. However, at this time, instead of creating and terminating the TCP session whenever necessary, the TCP session is continuously maintained.

As described above, it is possible to construct a connection controller that can organically control the connection device 200 in consideration of the number of the connection devices 200 constituting the site through the cloud connection device control system according to the embodiment of the present invention In addition, by building a connection controller through virtualization technology, rather than building a connection controller physically connected to the site, the system availability can be improved when the cost of system construction and maintenance is reduced.

Although the integrated management server 400 and the access point control server 300 are implemented separately from each other in the embodiment of the present invention, May be implemented as a single cloud solution system and may exist as a single module of a single cloud solution system.

Although only one integrated management server 400 and one access point control server 300 are shown in the drawing, a plurality of access point control servers 300 managed by one integrated management server 400 may exist .

More specifically, a traffic control method in the access device control server 300 will be described later, and a processor mounted in each device constituting the cloud access point device control system according to the embodiment of the present invention can execute the method according to the present invention Lt; RTI ID = 0.0 > commands.

Further, the processor is capable of processing instructions stored on a memory or storage device.

In addition, the communication network 1000 according to the embodiment of the present invention refers to a communication network for transmitting and receiving information between the respective components. In particular, the communication network 1000 according to an embodiment of the present invention includes various types of communication networks, such as an intranet network, The communication network implemented using the wired / wireless communication technology of the type can be mixed. In addition, the communication network 1000 according to the embodiment of the present invention may refer to the same intra-company network based on the site where the connection device 200 is located, or may refer to an external network.

Hereinafter, the main configuration and operation of the access point control server according to the embodiment of the present invention will be described in more detail.

FIG. 2 is a block diagram showing a main configuration of a connection device control server according to an embodiment of the present invention, and FIG. 3 is a block diagram illustrating a configuration of a communication device of a connection device control server according to an embodiment of the present invention .

Referring first to FIG. 1 and FIG. 2, the access point control server 300 according to an embodiment of the present invention refers to a virtualization server operating through virtualization technology. The access device control server 300 may include at least one or more virtual machines, such as a connection controller 330, a host OS 320, and a peripheral device 310.

The host OS 320 and the peripheral device 310 refer to the host machine. Here, the host machine refers to an actual physical server capable of creating an access controller based on virtualization technology, and the host OS 320 means an OS running on the host machine. In addition, the peripheral device 310 may be configured to include various hardware resources such as the communication device 311 and the storage device 312 as actual physical hardware resources of the host machine. For convenience of description, the present invention will be described by taking as an example that the peripheral device 310 comprises a communication device 311 that performs a function of transmitting and receiving information, and a storage device 312 that performs a function of storing information. But is not limited thereto.

Among them, the host OS 320 may include a hypervisor 321. The hypervisor 321 can create and manage a plurality of connection controllers 330 under the control of the integrated management server 400. The hypervisor 321 according to the embodiment of the present invention may be various virtualization methods such as full virtualization and semi-virtualization, and may be called a virtual machine monitor. In particular, the hypervisor 321 according to an embodiment of the present invention may be implemented in a Linux kernel-based virtual machine (KVM) and may be replaced with other hypervisors providing equivalent or similar effects / effects. In addition, the hypervisor 321 may include an emulator (not shown) that imitates the hardware of the virtual machine 300. The emulator (not shown) requests the hypervisor 321 to generate the connection controller 330 and resource allocation, which are virtual machines, and performs input / output (I / O) processing with the connection controller 330. The emulator (not shown) may be mapped and operated according to the connection controller 330, and the emulator (not shown) mapped to each connection controller 330 may be implemented as a different emulator.

The hypervisor 321 according to the embodiment of the present invention can transmit information on available resources to the integrated management server 400 according to a request of the integrated management server 400, And generates the connection controller 330 using the resource information. When information on at least one connection device 200 constituting a site mapped to the connection controller 330, that is, IP information, is received from the integrated management server 400, the generated connection controller 330 corresponds to the generated connection controller 330 And then storing the data. When the hypervisor 321 receives a message from the access device 200 through the communication device 311 of the peripheral device 310, the hypervisor 321 accesses the connection controller 330 that can process the received message, It is possible to confirm the pre-stored connection speed controller 330 corresponding to the connection controller 200 and support the process of transmitting the message to the connection controller 330 that has been confirmed.

In addition, the hypervisor 321 of the present invention can support the traffic control process for the terminal 100 through the communication device 311 of the peripheral device 310. For example, when information on the amount of traffic used by the terminal 100 is received from the communication device 311, the connection controller 330 transmits the information on the amount of traffic used by the terminal 100 to the connection controller 330, It can support the process to perform the billing process.

The traffic control method according to the embodiment of the present invention can be performed by the communication device 311. [ Here, the communication device 311 may be implemented as an independent device, such as a network interface card, which may be operated by a separate OS from the host OS 320. [ In this case, the communication device 311 can be physically or logically connected to the host OS 320 in the access point control server 300. In another embodiment, the communication device 311 may operate independently of the access point control server 300 in the form of a communication server.

3, the communication device 311 of the present invention includes a function setting module 311a, a terminal confirmation module 311b, A transmission rate confirmation module 311c, and a traffic control module 311d.

First, the function setting module 311a sets a rate limit function according to a command of the integrated management server 400. [ That is, the function setting module 311a sets a traffic volume limitation function according to the command, when a command for setting the traffic volume limitation function transferred from the connection management controller 400 is received from the connection controller 330. [ The function setting module 311a of the communication apparatus 311 performs the traffic volume limitation function in accordance with the command of the integrated management server 400. However, It is possible to automatically check whether or not the traffic volume limitation function setting is necessary and to set the traffic volume limitation function without intervention of the integrated management server 400 when it is determined to be necessary.

The terminal confirmation module 311b and the transmission rate confirmation module 311c are responsible for confirming information necessary for calculating the effective traffic amount of the present invention. That is, the terminal confirmation module 311b counts the number of terminals in the active state among the terminals 100 connected to each of the access devices 200 by checking the traffic amount limitation function through the function setting module 311a do. At this time, the terminal confirmation module 311b may count the number of active terminals in a predetermined period (for example, 3 seconds). Here, the active terminal 100 may refer to a terminal receiving traffic from an external Internet network (not shown), that is, a terminal 100 in which downlink traffic exists.

On the other hand, the transmission rate confirmation module 311c can confirm the transmission rate between the connected access devices 200 as the traffic volume limitation function is set through the function setting module 311a. At this time, the transmission rate confirmation module 311c checks the connection device 200 connected to the active terminal 100 identified by the terminal confirmation module 311b, and determines the transmission rate between the connected connection devices 200 You can count. That is, the terminal 100 counts the transmission rate from the external Internet network (not shown) to the connected device 200 to which the downlink traffic exists.

In one embodiment of the present invention, it is preferable to check the transmission speed for each access device 200, but depending on the system implementation method, the site to which the access device 200 to which the active terminal 100 is connected belongs It is also possible to confirm the transmission speed between all the access devices 200 in the site and then check the average value of the transmission speeds between all the access devices 200 that have been confirmed by the transmission speed between the access devices 200. [

The traffic control module 311d checks the validity of the terminal using the number of active terminals identified through the terminal confirmation module 311b and the transmission rate between the access devices 200 confirmed through the transmission rate confirmation module 311c Calculates the traffic volume, and controls the traffic to be delivered to the terminal 100 according to the calculated effective traffic volume. At this time, the traffic control module 311d of the present invention may apply a predetermined weight factor when calculating the effective traffic amount. Here, the weight may be a value that can be applied differently depending on the packet service type served by the terminal 100 and the service site type connected to the terminal 100. For example, it is possible to apply an embodiment such that a weight is differentiated according to a terminal 100 using a broadcasting service and a terminal 100 using a streaming service by confirming the type of packet service currently used by the terminal 100 Do.

The traffic control module 311d controls the traffic to be transmitted to the terminal 100 according to the calculated effective traffic amount. For example, when the traffic transmitted from the external Internet network (not shown) to the terminal 100 is 10 Mbps, the traffic control module 311d transmits 2 Mbps traffic to the terminal 100 according to the calculated effective traffic amount Can be controlled.

In addition, the communication device 311 configured by the above-described modules may be configured to include a multicore processor in one embodiment. At this time, the communication device 311 may operate by allocating individual cores for each connection controller 330. For example, a core for four data transmission can be allocated to the A-connection controller, a core for two data transmission can be allocated to the B-connection controller, and the connection device 200 corresponding to each of the connection controllers 330 can be allocated. The traffic of the terminal 100 connected to the terminal 100 can be processed by the corresponding core.

On the other hand, in another embodiment, a plurality of the communication devices 311 may exist. In this case, the A communication device is allocated to the A connection controller, the B communication device is assigned to the B connection controller, and the traffic of the terminal 100 connected to the connection device 200 corresponding to each connection controller is allocated to the communication device (311).

The meaning of the " communication device set in correspondence with the connection controller " described in the present specification is a concept including both of the above two cases.

Referring again to FIG. 2, at least one connection controller 330 operates in the access point control server 300 applied to the server virtualization environment, as described above. Here, the number of connection controllers 330 is not limited, and a plurality of connection controllers 330 may be generated in the available resource environment.

In particular, the connection controller 330 of the present invention is allocated for each site constituted by a plurality of access devices 200 as described above, and can support a signaling message processing process between the assigned access devices 200 and the like. For example, when the number of connected devices in the mapped site is 50, the connection controller 330 is generated by allocating resources that can be interlocked with 50 access devices under the control of the hypervisor 321, The connection device 200 can support the processing of the message transmitted from the access device 200. At this time, when the message according to the predetermined protocol is delivered through the hypervisor 321, the connection controller 330 removes the tunneling header of the message, checks the content of the message, An authentication procedure through interworking, etc., generates a response message according to the generated response message, and tunnels the generated response message to support the process of delivering the response message to the access device 200.

When the command for setting the rate limit function is received from the integrated management server 400, the connection controller 330 of the present invention transfers the command to the corresponding communication device 311, 311) to perform the traffic volume limitation function. When information on the amount of traffic used by the terminal 100 from the communication device 311 is transmitted via the hypervisor 321, the connection controller 330 determines whether the traffic amount of the terminal 100 Process can be performed.

The connection controller 330 may be configured to include a guest OS (not shown) and an application (not shown) for message processing, though it is not shown in the figure. The guest OS (not shown) in each connection controller 330 can be implemented by different kinds of OSs, and the type and number of applications (not shown) held by each connection controller 330 can be controlled by the corresponding connection controller 330 May vary depending on the type and number of connection apparatuses 200 to be processed.

In addition, the access point control server 300 according to the embodiment of the present invention further includes a security management apparatus (not shown) for detecting a network internal illegal access device and a terminal, and performing a function of detecting and automatically blocking a hacking attack threat .

The traffic control method in the access point control server 300 according to the embodiment of the present invention can be more clearly understood through a flowchart to be described later.

Hereinafter, the traffic control method will be described in more detail with reference to the access point control server 300 according to the embodiment of the present invention.

4 is a flowchart illustrating a traffic control method according to an embodiment of the present invention.

Referring to FIGS. 1 and 4, a traffic control method according to an embodiment of the present invention may be performed in the access point control server 300. To this end, the access point control server 300 confirms the number of terminals in the activated state (S103) and confirms the transmission speed between the connected access points 200 (S105). Thereafter, the effective traffic amount is calculated using the number of confirmed active terminals and the transmission speed between connected connected devices 200 (S107). The effective traffic amount can be calculated by applying a predetermined weight to a value obtained by dividing the number of active terminals by the transmission rate between the access points 200. [

Herein, each of the above steps may be performed in sequence, but may be performed inversely or concurrently. In other words, even if the traffic volume limiting function is not set, the number of terminals in the active state can be checked and the transmission speed between the access devices can be checked. If the traffic volume limitation function is set, the effective traffic volume can be calculated It is possible. Also, it is possible to check the transmission speed between the connected access devices and check the number of active terminals, and at the same time, confirm the information.

Then, the access point control server 300 can control the traffic of the terminal 100 according to the calculated effective traffic amount (S109).

The above-described traffic control method of the present invention will be described in more detail with reference to FIG.

5 is a flowchart illustrating a traffic control method according to an exemplary embodiment of the present invention.

Prior to description, it is assumed that a state in which the terminal 100 is connected to the connection device 200 and receives a packet from any content providing server (not shown) of the Internet network 2000 via a core network . Assume that the amount of traffic received by the terminal 100 at this time is 10 Mbps.

In this state, the access point control server 300 receives a command for setting the traffic volume limitation function from the integrated management server 400 (S201). The access point control server 300 that has received the command sets the traffic amount limitation function according to the command (S203). In one embodiment, the command may be entered by an administrator. In another embodiment, the access point control server 300 may automatically set the traffic volume limitation function without the intervention of the integrated management server 400 according to conditions such as the state of the access point 200 managed by the access point control server 300. [

As the traffic volume limitation function is set, the access point control server 300 confirms information necessary for calculating the effective traffic volume of the present invention. That is, the number of active terminals connected to the access point 200 is counted and checked (S205). The access point control server 300 can count the number of active terminals in a predetermined period (for example, three seconds). Here, the active terminal 100 may be the terminal 100 receiving traffic from the external Internet 2000. In other words, the terminal 100 in which downlink traffic exists may be counted to the terminal 100 in an active state, but the present invention is not limited thereto, and UPLINK traffic may exist The terminal 100 can be counted to the terminal 100 in the active state.

Then, the access point control server 300 checks the transmission rate with the connected access point 200 to check it (S208 to S209). At this time, the access point control server 300 can count the transmission rate between the connected access points 200 connected to the terminal 100 having the confirmed active state, and the process of checking the transmission rate can use various known configurations.

In one embodiment of the present invention, it is preferable to check the transmission speed for each access device 200, but depending on the system implementation method, the site to which the access device 200 to which the active terminal 100 is connected belongs It is also possible to confirm the transmission speed between all the access devices 200 in the site and then check the average value of the transmission speeds between all the access devices 200 that have been confirmed by the transmission speed between the access devices 200. [

Thereafter, the access point control server 300 calculates the effective traffic amount (S211). The effective traffic volume can be calculated using the inter-access device transmission rate and the number of active terminals identified in steps S205 and S209. That is, the access point control server 300 calculates the effective traffic amount of the terminal connected to the access device by applying a predetermined weight factor to the value obtained by dividing the number of active terminals by the transmission rate between the access points can do. Here, the predetermined weight factor may be differently applied depending on the packet service type serviced by the UE 100 and the type of the service site accessed by the UE. For example, it is possible to apply different weights according to the terminal 100 using the broadcasting service and the terminal 100 using the streaming service by checking the packet service type currently used by the terminal 100. [

When the effective traffic volume is calculated through this process, the access point control server 300 controls the traffic delivered to the terminal 100 according to the calculated effective traffic volume. That is, even if traffic (10 Mbps) is transmitted from the external Internet 2000 to the terminal 100, the access point control server 300 determines that the terminal 100 can accept (2Mbps) traffic is transmitted (S213).
