Description

[0001] The present invention relates to a wireless LAN bandwidth control method for an IP address unit corresponding to an Internet site,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention generally relates to a technology for estimating the characteristics of contents in use in an individual device in a wireless LAN network in real time and controlling the bandwidth allocation state for each device correspondingly.

More particularly, the present invention identifies an Internet site accessed by an individual device via a wireless LAN in a wireless LAN network, and estimates characteristics of content currently being used by the device. And then dynamically changing the wireless LAN bandwidth allocation state in units of IP addresses of the wireless LAN device in accordance with the estimated content characteristics.

The WLAN bandwidth control technology of the present invention can be preferably applied to a technical field such as a wireless LAN access point or a video bridge.

In recent years, personal digital devices such as smart phones, tablet PCs, and notebook PCs have become widespread, and wireless LAN technology to conveniently connect these devices to the Internet has become widespread. A wireless LAN access point is installed in a cafe, a restaurant, a reading room, a train, etc. as well as in a company or a home, and most digital devices existing in the space are connected to a wireless LAN.

Also, in recent years, the usage forms of streaming multimedia contents through a wireless LAN network are becoming common. It is very popular to access various videos through YouTube. In addition, it is common in recent years for a tablet PC or a notebook PC to access a portal site with a crop browser to watch sports broadcasts or game broadcasts. As the communication speed increases, high-quality real-time video streaming becomes possible through wireless LAN.

On the other hand, broadcast contents provided through IPTV or IP set-top box have been able to be enjoyed only in a wired environment in the past. In other words, IP broadcasters such as SK Broadband (B-TV), Katy (Olle TV) and LG U + TV (U + TV) provided broadcast contents to a set-top box connected to a broadband network. The dedicated set-top box displayed content playback screen only on the display device connected by HDMI or the like.

However, in recent years, it has become possible to enjoy such broadcast contents in a wireless LAN environment. IP broadcasters have begun to provide IP set-top boxes that re-transmit IP broadcast contents to a wireless LAN in the surrounding space. In a wireless LAN coverage, broadcast contents can be viewed on a mobile device or a sub-set-top box. At this time, since the local coverage of the wireless LAN network is very small, the wireless LAN coverage may be extended by using a video bridge or a wireless LAN extender.

However, a wireless LAN uses a certain amount of wireless bandwidth divided by a plurality of devices. It is not possible to predict how many people will use the wireless LAN, and it is a disadvantage in that it can not be controlled in any form. As a result, the wireless LAN communication situation may suddenly become poor. If you are listening to Internet lectures through a wireless LAN, listening to high-definition content, or downloading large files, the wireless LAN environment of other devices becomes very uncomfortable.

The wireless LAN has the disadvantage that the quality of the communication service is not guaranteed. The disadvantage is that in most applications, Internet search results are a bit late or the YouTube screen resolution is slightly lower. For IP broadcasters, however, this can not be ignored and must be solved. In other words, it is desired that the quality of the wireless LAN communication is always guaranteed for the device watching the broadcast contents of the IP broadcasting company through the wireless LAN. This is true even if the video bridge participates in wireless LAN communication or acts as a wireless LAN access point.

Meanwhile, there is a method for improving the communication quality of the wireless LAN. If a combination of the Traffic Class field and the Flow label field of the IPv6 or the TOS field of the IPv4 is used, a slight quality guarantee (QoS) effect can be expected. However, since these prior art approaches to preempt some packets in case of IP packet collision, there is practically no effect if the same level of field manipulation is performed in another Internet service.

Accordingly, there is a need for a technique capable of solving the problems of the related art and ensuring an appropriate level of wireless LAN communication quality for services related to video audio, in particular, broadcasting contents of IP broadcasting companies.

SUMMARY OF THE INVENTION An object of the present invention is to provide a technique for real-time estimating of the characteristics of a content being used by an individual device in a wireless LAN network and controlling the bandwidth allocation state for each device in response to the estimation.

In particular, it is an object of the present invention to provide a method and apparatus for identifying an Internet site connected to an individual device via a wireless LAN in a wireless LAN network, roughly estimating the characteristics of the content currently being used by the device, And dynamically changing a wireless LAN bandwidth allocation state in units of an IP address of the wireless LAN device.

In order to achieve the above object, the present invention provides a method of controlling a bandwidth of a wireless LAN in an IP address unit corresponding to an Internet site according to the present invention, A first step of identifying a content category; A second step of identifying an IP address for one or more devices connected to the wireless LAN network; A third step of identifying an Internet site connected through an external network for each IP address; A fourth step of estimating a content category in which the device uses the wireless LAN for each IP address corresponding to the identified Internet site; And a fifth step of setting a wireless LAN bandwidth allocation amount corresponding to the estimated content category for each IP address.

The method of controlling a bandwidth of a wireless LAN according to the present invention includes: proceeding to a second step when a connection event of a new device to a wireless LAN network is identified; And if the monitoring timeout event is identified for a predetermined time period, proceeding to the third step.

In the present invention, the content category includes a non-broadcast category in which the assignment of the wireless LAN bandwidth is a predetermined value and a priority category in which the priority of the wireless LAN bandwidth allocation is relatively lower than that of the broadcast category. At this time, the non-broadcast category may include at least one of a video streaming category, an audio streaming category, and a normal data category in a descending order of priority of the WLAN bandwidth allocation. In addition, the IP address may include an internal local IP address and an IPv6 unique IP address.

The fifth step of the present invention may include configuring a bandwidth for each of the first bandwidth allocation values preset for the one or more IP addresses estimated in the broadcast category.

In operation 512, the remaining bandwidth allocated in operation 51 is calculated from the total bandwidth of the wireless LAN. And setting the bandwidth of each of the second bandwidth allocation values preset to be smaller than the first bandwidth allocation value within the limit of the remaining bandwidth for one or more IP addresses estimated in the non-broadcast category.

In operation 512, the remaining bandwidth allocated in operation 51 may be calculated from the total bandwidth of the wireless LAN. The method further comprises a step 523 of setting a bandwidth for each of the one or more IP addresses estimated in the non-broadcast category by dividing the remaining bandwidth by a ratio.

Meanwhile, a computer-readable nonvolatile recording medium according to the present invention records a program for causing a computer to execute a wireless LAN bandwidth control method for an IP address unit corresponding to an Internet site as described above.

According to the present invention, it is possible to control the bandwidth allocation in units of individual devices in a wireless LAN network. By estimating the content characteristics of currently connected Internet sites and adjusting the bandwidth according to the bandwidth characteristics, So that it can be stabilized.

The present invention is advantageous in that the content wireless retransmission function of the video bridge can be stably operated even if the number of people increases in a wireless LAN network environment in which a plurality of people share.

According to the present invention, a video bridge, which is linked with a service provider for a service providing a kind of broadcasting contents such as IPTV or IP set-top box (for example, B-TV, OleTV, LG U + There is an advantage that it is possible to guarantee that the content service can be always provided stably.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a conceptual diagram illustrating the overall configuration of a wireless LAN network system to which a bandwidth control technique according to the present invention is applied.

Referring to FIG. 1, a plurality of wireless LAN devices 210 to 260 use the Internet through a wireless LAN access point 100. The B-TV 320, the Ole TV 330, the U + TV 340, and the U-TV 340 shown in FIG. 1 are connected to the Internet service servers 310 to 350 through the Internet. , And the YouTube 350 are examples.

These Internet service servers 300 provide various kinds of contents according to their respective business models. The neaver 310 mainly provides general data (normal data) because it provides a search service or an information providing service. The B-TV 320, the Ole TV 330, and the U + TV 340 provide broadcast content as a server of an IP broadcaster. In addition, YouTube 350 provides general video streaming. Other types of content can be defined besides these. For example, Internet sites that mainly provide high-quality digital audio (for example, FLAC) are emerging.

At this time, the broadcasting contents and the video streaming are slightly different in character. Broadcasting content is generally a paid service and it is very important to make it possible to enjoy the contents in the most pleasant environment. It is hardly understood that the video resolution is repeatedly low or buffering happens frequently. On the other hand, video streaming is free, or at very low cost, and it is sufficient to provide the best effort video. Sometimes the video resolution goes down or buffering happens, but you can get away without complaining.

In FIG. 1, the wireless LAN coverage that the wireless LAN access point 100 can cover is the area indicated by # 1. For example, because the house is quite large, the wireless LAN access point 100 placed in the living room does not provide wireless LAN communication to a small room placed at the last corner of the house. 1, the two wireless LAN devices 250 and 260 perform wireless LAN communication via the video bridge 240. The video bridge 240 is connected to the video bridge 240 via the video bridge 240. [ In this specification, devices that perform wireless LAN communication provided by a specific wireless LAN access point 100 may be referred to as 'internal devices'.

Each of these wireless LAN devices 200 is assigned an IP address. These IP addresses are IP addresses that are temporarily allocated locally by the wireless LAN access point 100 as a kind of Internet router, that is, internal local IP addresses. However, since the IP address is abundant in the IPv6 system, each device can be assigned a unique IP address. Accordingly, some of the IP addresses of the wireless LAN device 200 may be IPv6 specific IP addresses.

In the present invention, it is assumed that a plurality of wireless LAN devices 210 to 260 jointly use the wireless LAN bandwidth provided by the wireless LAN access point 100 and use various types of Internet contents. It is an object of the present invention to guarantee a wireless LAN communication of an appropriate quality for a wireless LAN device using an Internet service related to video audio. Especially, it is an important goal to always guarantee the quality of wireless LAN devices watching broadcast contents.

As described above, the present invention manages the quality of the wireless LAN in units of devices. Since the device itself is not important and the characteristics (category) of the content viewed by the device are important, the wireless LAN access point 100 transmits the IP address So that the wireless LAN device can be distinguished. This is because the IP address does not change while the wireless LAN communication is maintained, and the wireless LAN access point 100 can effectively refer to the IP address because the IP address is input in the header area.

FIG. 2 is a block diagram illustrating an internal functional configuration of a wireless LAN access point 100 to which a bandwidth control technique according to the present invention is applied. FIG. 3 is a diagram illustrating an IP FIG. 4 is a flowchart illustrating an overall process of a wireless LAN bandwidth control method in an address unit; FIG.

2, the WLAN access point 100 includes a site category identification unit 110, an internal IP address identification unit 120, an access site identification unit 130, a content category estimation unit 140, A LAN bandwidth allocation unit 150, an event identification unit 160, and an Internet site database unit 170.

Meanwhile, the bandwidth control technique according to the present invention can be applied to devices such as a video bridge and a wireless LAN extender in addition to a wireless LAN access point.

The overall process of the method of controlling the wireless LAN bandwidth in units of IP addresses corresponding to the Internet site according to the present invention will be described in detail.

Step S110: First, the site category identification unit 110 refers to the Internet site database unit 170 and identifies a content category corresponding to an average characteristic of the content to be served to a plurality of Internet sites.

In the present invention, the content category relates to whether or not it includes video audio and the content characteristics according to the importance of the content.

In one embodiment, the content category may be defined as a broadcast category and a non-broadcast category. The broadcast category means content provided by an IP broadcasting company, and is a content category in which the allocation of the wireless LAN bandwidth should be ensured as a preset value. Also, the non-broadcast category means other contents, and the priority of the wireless LAN bandwidth allocation is lower than that of the broadcast category. At this time, the non-broadcast category includes a video streaming category (e.g., YouTube, Naver TV, etc.), an audio streaming category (e.g. Naver Music, Bucks etc.), a normal data category , Next, Google, etc.). Within the non-broadcast category, the video streaming category has the highest priority and the normal data category has the lowest priority.

In the present invention, the content category is previously set for various Internet sites in correspondence with the characteristics of the content mainly provided in the site, and is stored in the Internet site database unit 170. At this time, if the wireless LAN access point 100 is a device provided by a specific IP broadcasting service provider, the content category of the Internet site of the corresponding IP broadcasting service provider and the Internet site of the other IP broadcasting service provider may be set separately. For example, the content category of the Internet site of the other IP broadcasters can be set to the video streaming category of the non-broadcasting category.

Step S120: The internal IP address identifying unit 120 identifies an IP address to one or more internal devices 200 connected to the wireless LAN network. The wireless LAN access point 100 is often configured to be able to discovery the IP addresses of associated wireless LAN devices.

Steps S130 and S140: The connection site identification unit 130 identifies the Internet sites connected through the external network for each IP address. That is, it identifies which Internet site each of the wireless LAN devices 200 accesses.

The content category estimating unit 140 determines that the corresponding internal devices 210 to 260 are in correspondence with the identified Internet site by referring to the information that the site category identifying unit 110 identifies the content category for each Internet site And estimates a content category using the wireless LAN.

Step S150: The wireless LAN bandwidth allocating unit 150 sets a wireless LAN bandwidth allocation amount corresponding to the estimated content category for each IP address. The wireless LAN bandwidth to such a degree that the high-definition broadcast contents can be enjoyed without any problem is preferentially allocated to the broadcast category. And allocates the wireless LAN bandwidth for the non-broadcast category using the remaining bandwidth allocated to the broadcast category.

A process of setting a wireless LAN bandwidth allocation amount according to a content category in the present invention will be described later with reference to FIGS. 4 and 5. FIG.

Meanwhile, in the present invention, when the wireless LAN access point 100 sets the bandwidth in the wireless LAN network, the airtime of the wireless LAN communication is actually controlled to effectively implement the bandwidth setting. For the technique, refer to Applicant's patent application No. 10-2015-0094474 (filed on July 2,1205, 201) entitled " Air Time Control Method in WLAN Network and Recording Medium therefor ".

Steps S160 and S170: The event identifying unit 160 monitors whether or not an event for the wireless LAN network is generated. If a new device is connected to the wireless LAN network, the process proceeds to step S120. It is preferable to completely reset the allocation state of the wireless LAN bandwidth from the beginning since the new internal device can not know in advance which site to connect to.

In addition, if the monitoring timeout event for the preset time period (for example, 60 seconds) is identified, the event identifying unit 160 proceeds to step S130. It is preferable that the connection state of the Internet site changes every moment, so it is preferable to identify the connection state of the Internet site at a predetermined time and to reflect the result.

4 is a flowchart illustrating a first embodiment of a process in which a wireless LAN access point 100 allocates a bandwidth in accordance with a content category set in an Internet site to which the wireless LAN device 200 is currently connected according to the present invention . The process of FIG. 4 corresponds to step S150 in the flowchart of FIG. 3.

Step S210: First, the wireless LAN bandwidth allocation unit 150 sets bandwidths for the first bandwidth allocation values previously set for one or more IP addresses estimated in the broadcasting category in step S140. The wireless LAN bandwidth to such an extent that the high-definition broadcast contents can be enjoyed without any problem is preferentially allocated to the broadcast category such as the broadcast content of the IP broadcast provider. The first bandwidth allocation value is set for each IP address estimated in the broadcast category, that is, for each wireless LAN device.

On the other hand, step S210 is sufficient in the embodiment focused on ensuring smooth appreciation of broadcast contents of an IP broadcaster. On the other hand, in the embodiment in which overall quality of service is guaranteed for viewing multimedia contents such as YouTube or Naver TV, the following steps are performed.

Step S220: The wireless LAN bandwidth allocation unit 150 calculates the remaining bandwidth allocated and remaining in the entire wireless LAN bandwidth in step S210. The total wireless LAN bandwidth that the wireless LAN access point 100 can provide is limited. For example, 802.11a / b / g / n / ac, a wireless LAN standard, provides bandwidths of 54 Mbps, 11 Mbps, 54 Mbps, 300 Mbps, and 867 Mbps, respectively. The remaining bandwidth allocated in step S210 is calculated from the total wireless LAN bandwidth, and this remaining bandwidth is a margin to be allocated to the remaining wireless LAN devices.

Steps S230 to S260: The wireless LAN bandwidth allocator 150 allocates a second bandwidth allocation value smaller than the first bandwidth allocation value within the upper limit of the remaining bandwidth for one or more IP addresses estimated in the non-broadcast category Set the bandwidth.

As described above, since the request for maintaining the communication quality is low for the non-broadcast category, it may be sufficient to allocate the first band allocation value to the broadcast category in step S210.

However, when a stable service is required for a video streaming service such as YouTube or Naver TV, a non-broadcast category video streaming category (eg, YouTube, Naver TV, etc.), an audio streaming category (eg Naver Music, A wireless LAN bandwidth preset for each device is assigned to an IP address estimated to be a data category (e.g., Naver, Next, Google, etc.), i.e., a wireless LAN device. At this time, the higher the priority of the wireless LAN bandwidth allocation is, the more the wireless LAN bandwidth is allocated even in the non-broadcast category.

If the wireless LAN bandwidth allocation for the remaining wireless LAN devices 200 is performed within the remaining bandwidth limit, the process proceeds to step S250 and the bandwidth allocation process is regarded as successful.

On the other hand, if it is determined that the wireless LAN bandwidth allocation for the remaining wireless LAN devices 200 can not be performed with respect to the remaining bandwidth limit, the process proceeds to step S260, and the bandwidth allocation according to the above process is regarded as inoperable. In this case, the process of adjusting the second bandwidth allocation value may be performed, or the first embodiment of FIG. 4 may be abandoned and the process may proceed to the second embodiment of FIG.

5 is a flowchart illustrating a second exemplary embodiment of a process in which the wireless LAN access point 100 allocates a bandwidth according to a content category set in an Internet site to which the wireless LAN device 200 is currently connected according to the present invention . The process of FIG. 5 corresponds to step S150 in the flowchart of FIG. 3.

Step S310: First, the WLAN bandwidth allocation unit 150 sets a bandwidth for each of the first bandwidth allocation values previously set for one or more IP addresses estimated in the broadcasting category in step S140. The wireless LAN bandwidth to such an extent that the high-definition broadcast contents can be enjoyed without any problem is preferentially allocated to the broadcast category such as the broadcast content of the IP broadcast provider.

Step S320: The WLAN bandwidth allocation unit 150 calculates the remaining bandwidth allocated and remaining in the entire WLAN bandwidth in step S310. The total wireless LAN bandwidth that the wireless LAN access point 100 can provide is limited. The residual bandwidth allocated in step S310 is calculated from among the total wireless LAN bandwidths, and the remaining bandwidth is a margin to be allocated to the remaining wireless LAN devices.

Step S330: The wireless LAN bandwidth allocating unit 150 divides the remaining bandwidth of the one or more IP addresses estimated in the non-broadcast category, that is, the remaining wireless LAN devices, by appropriate ratios to set bandwidths.

As described above, since the request for maintaining the communication quality is low for the non-broadcast category, it may be sufficient to allocate the first band allocation value to the broadcast category in step S310. However, in an embodiment in which a stable service is provided for a video streaming service such as YouTube or Naver TV, the IP address estimated by the video streaming category, the audio streaming category, and the normal data category, which are non-broadcast categories, .

Since the number of remaining wireless LAN devices can not be predicted in advance, the remaining bandwidth is appropriately distributed in step S330. At this time, preferably, the distribution ratio is set to be higher as the priority of the wireless LAN bandwidth allocation is higher, even in the non-broadcast category.

6 to 8 are conceptual diagrams illustrating a change in the allocation state of the wireless LAN bandwidth in the present invention in response to which Internet site the wireless LAN devices 200 access in the wireless LAN network.

First, a wireless LAN bandwidth (for example, 25 Mbps) sufficient to listen to high-definition broadcast content to a wireless LAN is preferentially allocated to an IP address connecting an Internet site belonging to a broadcast category, for example, the OleTV TV 330. [

In addition, a wireless LAN bandwidth (for example, 10 Mbps) is allocated to an IP site that connects to an Internet site belonging to the video streaming category, for example, the YouTube 350, to enjoy a certain amount of video contents. If there are not enough wireless LAN devices 200 or the amount of generated wireless LAN traffic is small, the IP address connected to the YouTube 350 may be allocated to the allocated bandwidth of 10 Mbps Or more. However, even when the amount of generated wireless LAN traffic is larger than the capacity of the entire wireless LAN bandwidth, the IP address connected to the YouTube 350 is guaranteed to have the allocated bandwidth of 10 Mbps.

In addition, a wireless LAN bandwidth (for example, 5 Mbps) is allocated to an Internet site belonging to the normal data category, for example, an IP address connecting the neighbor 310, to the extent that a minimum internet connection is possible. Depending on the implementation, it may be configured not to allocate the wireless LAN bandwidth for the normal data category.

Meanwhile, the present invention can be embodied in the form of computer readable code on a computer-readable non-volatile recording medium. Such a non-volatile recording medium includes all kinds of storage devices for storing computer-readable data such as a hard disk, an SSD, a CD-ROM, a NAS, a magnetic tape, a web disk, a cloud disk, The code may be distributed and stored in the storage device of the computer.
