Description

Wireless Internet access management system and method linked to higher network access quality

The present invention generally relates to a technology for stably guaranteeing communication quality of a wireless network by controlling a wireless network connection of a user equipment in a customer premises in response to a communication situation by a customer premises device (CPE).

In particular, in the present invention, the customer premises device (CPE) detects the speed and state of the upper network in real time and controls wireless network access of the home user equipment in the lower network in response thereto. It relates to a wireless Internet access management technology for stabilizing communication quality of a wireless network by pseudo-uniformly distributing traffic.

In recent years, as digital content playback devices such as smartphones, tablet PCs, laptop computers, and IP set-top boxes have become widespread, and Internet content services such as Netflix, YouTube, Google Movies, and Apple Music have become commonplace, wireless Internet in a certain space (home). The technology that enables users to use the device at high speed has become very important.

In order to provide wireless Internet service in a certain space, such as a house, a cafe, a hotel, an airport, etc., a person who manages the space requests a broadband Internet service from a communication service company. Then, the installation staff of the communication service company visits the place, installs various network devices, and performs initial setup and device registration so that they can operate normally. When the service subscription and opening process is completed, broadband Internet access becomes possible, and wireless Internet access becomes possible by installing a wireless router for the space. In the past, broadband wired network service was common, but recently, it is also possible through 4G and 5G mobile communication networks.

1 is a diagram showing an example of an Internet access environment to which the present invention is applied. One or more in-house user devices, such as various mobile devices and smart devices, are located in each space. In this way, in order for in-house user equipment to wirelessly access the broadband Internet, a small network relay device that provides wireless communication coverage for a corresponding space is required. These are commonly referred to as CPE, AP, ROUTER, Small-Cell, Femtocell, etc., and are collectively referred to as Customer Premises Equipment (CPE). For convenience of explanation, in this specification, the present invention is described on the assumption of an AP router.

When wireless access devices are concentrated in a certain space where wireless Internet service is provided, the customer premises device (CPE) accepts wireless access to devices attempting to access it within its performance limit. For example, assuming that the number of customers in a cafe suddenly increases from 10 to 100, the CPE installed in the cafe suddenly receives a wireless connection request from 150 smartphones. In this case, the CPE will accommodate all 150 additional connection requests if its chipset capabilities allow.

However, the quality of the CPE's lower network service is generally degraded by the operation of the customer premises equipment (CPE). Although it is physically located near the CPE and the radio signal strength (RSSI) is very high, there is a situation in which the quality of actual Internet service experience is very deteriorated.

2 is a diagram illustrating an example of a network speed standard for an Internet video service. The specific numbers are slightly different for each OTT service provider due to differences in streaming and video compression technologies. In FIG. 2, examples of YouTube and Netflix, which are used most in the world, are given. Referring to FIG. 2, a user can use these video services only when the effective speed of a wireless connection provided to an in-house user device is 2.5 Mbps or 3 Mbps or more. In addition, a wireless connection speed of 564 Kbps or higher must be provided to enable playback of 270p, the lowest quality of Naver video, and a wireless connection speed of 400 Kbps or higher must be provided to enable streaming music listening and normal web surfing.

However, when there are many wireless Internet users in a specific space, the minimum wireless access speed may not be reached. In particular, even if the total number of wireless Internet users existing in the corresponding space is less than the limit, the same problem occurs when these users are densely present. In this case, the customers of the space tend to be very dissatisfied.

An object of the present invention is to provide a technology for stably guaranteeing communication quality of a wireless network by generally controlling a wireless network connection of a user equipment in a customer premises in response to a communication situation by a customer premises device (CPE).

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

In the wireless Internet access management system according to the present invention, in order to provide wireless Internet access to a plurality of in-house user devices that are generally present in a fairly large space, a plurality of customer premises equipment (CPE) is distributed and arranged in the space. It is a technology that stabilizes the communication quality of a wireless network by effectively distributing or restricting access to wireless traffic.

In general, the wireless coverage of customer premises equipment (CPE) is only tens of meters even when there are no obstacles, and there is a limit to the number of wireless connections that can be accommodated by one CPE. Should be installed. For example, in a 500 ㎡ store, 3 CPE units should be placed, and in a 1500 ㎡ space, 10 units should be placed, and a larger place, such as 2000, can be accommodated. If you can do it, you'll need dozens of hotel convention centers. These customer premises equipment (CPE) is a device that provides wireless Internet access to a plurality of in-house user equipment existing in a corresponding space.

3, the wireless Internet access management system includes a plurality of customer premises devices (CPE1 to CPEn) (101 to 103: 100) providing wireless Internet access in a corresponding space, and these customer premises devices 100 are each managed. It is configured to include a connection management server 200 for synchronizing the connection management table. At this time, a set of in-house user devices connected to each of the customer's in-house devices 101 to 103 and using the wireless Internet through this is indicated as a subgroup.

Observing the conventional wireless Internet usage pattern, it is common that in-house user devices are concentrated in some subgroups, while in-house user devices are not very much in other subgroups. In the former case, the customer's premises equipment (CPE) allows wireless access to the maximum number of premises user equipments within its own performance limit. For example, if the chipset's capabilities permit, it allows wireless access to 150 in-house user devices. In this case, since these 150 in-house user devices share the connection speed of the upper network of the customer premises equipment (CPE), each wireless communication speed will be very slow. On the other hand, in the latter case, for example, 7 in-house user devices are connected to a customer in-house device (CPE), so that very comfortable wireless Internet communication can be enjoyed. However, in this case, the ability of the customer premises equipment (CPE) to provide wireless Internet communication is wasted.

In order to solve such a conventional problem, in the present invention, the customer premises equipment (CPE) appropriately limits the number of wireless Internet access of the premises user equipment in consideration of the connection quality of the upper network. In the case of more connection requests, other customer premises devices (CPEs) existing in the corresponding space can be linked to provide wireless Internet access, and if all accommodation spaces are full, the existing devices are used through queue management. When leaving the space, the customer's premises equipment (CPE), where the idle capability has occurred, provides wireless Internet access in standby order.

An operation method of such a wireless Internet access management system will be described in detail with reference to FIG. 4.

4 is a flow chart showing the entire process of a wireless Internet access management method linked to a higher network connection quality performed by the wireless Internet access management system in the present invention.

Step (S110): First, the first customer premises device (CPE) sets a specific minimum guaranteed speed (eg, 1 Mbps) for the sub-network. In this specification,'lowest guaranteed speed' means the minimum network speed quality that the customer's premises device (CPE) tries to provide to wireless Internet accessors in consideration of the type of wireless Internet service and the nature of the content that people will mainly use in the space. do. For convenience of calculation, in this specification, the lowest guaranteed rate is assumed to be 1 Mbps.

Step (S120): There are a plurality of in-house user devices in the corresponding space, among which a first in-house user device performs wireless Internet search to discover a first customer in-house device (CPE) and requests wireless Internet access.

Steps (S130, S140): The first customer premises device (CPE) acquires an access speed of a higher network to which it is currently connected, for example, WAN, 4G, 5G, and the like. The measurement of the connection speed may be performed through the own hardware of the first customer premises device (CPE), or may be performed using a quality measurement server for each communication company or a NIA server (http:/ /speed.nia.or.kr). For convenience of explanation, it is assumed that the current high-level network access speed of the first customer premises device (CPE) is 80 Mbps. Meanwhile, even in a plurality of customer premises devices (CPEs) arranged in the same space, different access speeds of a higher network may be obtained according to different circumstances or different types of networks. However, for convenience of explanation, it is assumed in this specification that the connection speed of the upper network for all CPEs is 80 Mbps.

Then, the first customer premises equipment (CPE) is the instantaneous capacity of the first customer premises equipment (CPE) from the obtained upper network connection speed (e.g. 80 Mbps) and the lowest guaranteed speed (e.g. 1 Mbps). instantaneous capacity). In the example above, the instantaneous capacity is 80. That is, it means that the first customer premises device (CPE) can allow wireless Internet access of the premises user equipment only up to 80 units in the sub-network. If the connection speed of the upper network increases or decreases, the instantaneous capacity increases or decreases in connection with it.

Meanwhile, in FIG. 4, after a wireless Internet access request is received from a lower network, the connection speed of the upper network is measured and the instantaneous capacity is calculated, but the order is not limited thereto. The connection speed of the upper network may be stable, or the process of calculating the instantaneous capacity may be performed in advance immediately after booting the device (CPE) for convenience of product implementation.

Steps (S150 to S170): The first customer premises device (CPE) allows wireless Internet access up to its instantaneous capacity, that is, up to 80 units, to a request for wireless Internet access from a lower network by the first in-house user device. do. In-house user devices that are allowed access in this way are guaranteed to have a wireless Internet connection quality of at least the lowest guaranteed speed (eg, 1 Mbps). If the number of connected devices is less than the instantaneous capacity, a more comfortable connection quality can be enjoyed. An important point in the present invention is that even if the quality of wireless Internet access decreases due to an increase in congestion, it does not drop below the minimum guaranteed speed (eg, 1 Mbps).

Then, the access device list is managed by reflecting the fact that the first in-house user device is wirelessly connected to its access management table. In addition, since the first in-house user device may be managed in a standby state by another customer in-house device (CPE), the connection management table synchronization is performed between a plurality of customer in-house devices (CPEs) arranged in the corresponding space. Remove. This process will be described in detail with reference to FIGS. 5 to 7.

Step (S180): On the other hand, when the first customer CPE reaches its instantaneous capacity, that is, when 80 units are already accessing the wireless Internet, it temporarily rejects the wireless Internet access request from the first in-house user device. Then, queue management is performed by assigning a connection waiting sequence number to the first in-house user device and adding a corresponding device item to its own connection management table in a standby state. In this case, the first customer's premises equipment (CPE) is a user equipment of the first premises through its own or a service server, and it notifies information that wireless Internet service is temporarily unavailable because there are many current users through SMS or Push Message. It is desirable.

Step (S190): The first in-house user device, whose wireless Internet access request is temporarily denied by the first customer in-house device (CPE), searches whether there is another non-attempt customer in-house device (CPE) in the corresponding space. That is, it is to search whether a customer premises device (CPE) that has no record of temporarily rejecting a wireless Internet access request within a preset time (eg, 5 seconds) exists in the corresponding space.

Step (S200): If another non-attempt customer premises device (CPE) is found as a result of the above search, the process proceeds to step (S130) and the above process is repeatedly performed for the corresponding non-attempt customer premises device (CPE).

Step (S210): On the other hand, as a result of the above search, if it fails to find another non-attempt customer premises device (CPE), all customer premises devices capable of physically wireless communication with the first in-house user device in the corresponding space ( CPE) has requested wireless Internet access, but has been temporarily denied, so the first in-house user device enters the connection standby state. In this case, the first in-house user equipment is queue-managed in a connection standby state in several customer in-house devices (CPEs).

Steps (S220, S230): Referring to FIG. 3, in-house user devices are individually connected to a plurality of customer in-house devices (CPEs) in the corresponding space. When the user leaves the corresponding space or disables the wireless communication function, the wireless Internet connection of the in-house user device may be disconnected. In this specification, for convenience of description, these are referred to as a customer premises device (CPE) and a second premises user device, respectively.

When the second customer premises device (CPE) identifies the disconnection of the second in-house user device connected to the sub-network, the second customer premises device (CPE) is The list of connected devices is organized by deleting the in-house user devices, and accordingly, there is room to allow one more access. Accordingly, the second customer premises equipment (CPE) enters a state in which wireless Internet access is allowed to the premises user equipment in the queue according to the connection waiting order. At this time, for convenience of explanation, the in-house user device in the access management table of the second customer in-house device (CPE), the in-house user device that has the most advanced connection waiting order, is called a third in-house user device.

Steps (S240, S170): The second customer in-house device (CPE) permits wireless Internet access to a specific third in-house user device in response to the connection waiting sequence number. In-house user devices in the waiting state for connection in the corresponding space periodically (e.g., once a second) to request wireless Internet access while periodically (e.g., once a second) around customer premises devices (CPE), the second customer premises device (CPE) is a third The wireless Internet access request from the in-house user device is allowed, while other in-house user devices are denied even if a wireless Internet access request is made earlier than the third in-house user device.

Then, the second customer premises device (CPE) manages the access device list by reflecting the fact that the third premises user device is wirelessly connected to its access management table. In addition, since the third in-house user device may be managed in a standby state in another customer in-house device (CPE), the connection management table is synchronized between a plurality of customer in-house devices (CPEs) arranged in the corresponding space. Remove. This process will be described in detail with reference to FIGS. 8 to 10.

FIG. 5 is a diagram illustrating a first embodiment of a process in which a plurality of customer premises devices (CPEs) 100 perform a cooperative connection in the present invention. FIG. 6 is a diagram illustrating a state in which an in-house user device connects to a specific subgroup wireless Internet and synchronizes a connection management table accordingly, and FIG. 7 is a diagram illustrating a state in which a connection management table is managed at this time. .

First, referring to FIG. 5, n customer premises equipment (CPE) are arranged in a corresponding space, each of which provides wireless Internet access to in-house user equipment within their own coverage and instantaneous capacity limits. In FIG. 5, the CPEn 103 has not reached its instantaneous capacity because there are only 74 in-house user devices connected to the wireless Internet, and the rest of the customer's in-house devices all reach their instantaneous capacity and queue several units each. It is in a state of having.

In this state, as someone enters the space, the in-house user device 11 possessed by that person tries to access the wireless Internet. Although a wireless Internet connection was requested to the CPE1 (101), the in-house user device 11 was the 87th terminal that requested a wireless Internet connection to the CPE1 (101). Accordingly, 80 in-house user devices were connected to the CPE1 101 wirelessly, and 6 were in the queue before, but the in-house user devices 11 were added to the queue of CPE1 101 with the connection waiting number 7 .

Since the in-house user device 11 has been temporarily rejected by the CPE1 101, it searches for the existence of another non-attempt customer in-house device (CPE) in the corresponding space, and finds the CPE2 102 accordingly. The in-house user device 11 requested wireless Internet access from the CPE2 102, but the in-house user device 11 was the 103rd terminal requesting wireless Internet access from the CPE2 102. Accordingly, 80 in-house user devices were connected to CPE2 (102) with wireless Internet access, and 22 were previously in the queue, but the in-house user devices 11 were added to the queue of CPE2 (102) with the connection waiting number 23. .

As described above, the process of searching a non-attempt customer's premises equipment (CPE), requesting a wireless Internet connection, temporarily rejecting and managing a queue, is repeated, and then the CPEn 103 allows a wireless Internet connection request. Accordingly, the in-house user device 11 is connected to the CPEn 103 by wireless Internet and joins the subgroup n.

In this case, the present invention must synchronize the access management table to ensure uniformity of management data.

6, the CPEn 103 adds the in-house user device 11 to the access device list of its own connection management table, and sends a device join message (Join_MAC) for the in-house user device 11 to a connection management server ( 200). Upon receiving the device join message (Join_MAC), the access management server 200 transmits a device deletion message (Delete_MAC) for the in-house user device 11 to one or more customer in-house devices (CPE) that are mutually related in the corresponding space. Do it. Upon receiving the device deletion message (Delete_MAC), the in-house devices CPE1, CPE2, ..., respectively, search the queue of their own access management table and delete the in-house user device 11.

Referring to FIG. 7, 3A-F2-12-34, which is the identification information of the in-house user device 11, was queued with the connection waiting number 7 in the access management table of CPE1 101, and the access management of CPE2 102 In the table, the queue was managed with the connection waiting number 23. However, after the in-house user device 11 is wirelessly connected to the CPEn 103, the identification information of the in-house user device 11 is identified in the access management table of the CPE1 101 and CPE2 102 through synchronization of the access management table. 3A-F2-12-34 has been deleted.

FIG. 8 is a diagram illustrating a second embodiment of a process in which a plurality of customer premises devices (CPEs) 100 perform a cooperative connection in the present invention. FIG. 9 is a diagram illustrating a state in which an in-house user device accesses the wireless Internet to a specific subgroup and synchronizes a connection management table accordingly, and FIG. 10 is a diagram illustrating a state in which a connection management table is managed at this time. .

First, referring to FIG. 8, n number of customer premises equipment (CPE) are arranged in a corresponding space, each of which provides wireless Internet access to the premises user equipment within the limits of their coverage and instantaneous capacity. In FIG. 8, all of the n customer premises equipment (CPE) have reached their instantaneous capacity and each has several queues.

In this state, as someone enters the space, the in-house user device 12 possessed by that person attempts to access the wireless Internet. Although a wireless Internet connection was requested to the CPE1 (101), the in-house user device 12 was the 81st terminal that requested a wireless Internet connection to the CPE1 (101). Accordingly, 80 in-house user devices were connected to the CPE1 101 by wireless Internet access, and the in-house user devices 12 were added to the queue of the CPE1 101 with the connection waiting number 1.

Since the in-house user equipment 12 has been temporarily rejected by the CPE1 101, it searches for the existence of another non-attempt customer in-house equipment (CPE) in the corresponding space, and finds the CPE2 102 accordingly. The in-house user device 12 requested wireless Internet access from the CPE2 102, but the in-house user device 12 was the 103rd terminal that requested wireless Internet access from the CPE2 102. Accordingly, 80 in-house user devices were connected to the CPE2 (102) wirelessly and 22 were in the queue, but the in-house user devices 12 were added to the queue of CPE2 (102) with the connection waiting number 23. .

In this way, the process of searching the customer's premises equipment (CPE), requesting wireless Internet access, temporarily being denied, and managing the queue is repeated. The in-house user device 12 requested wireless Internet access to the last CPEn 103, but the in-house user device 12 was the 97th terminal that requested wireless Internet access to the CPEn 103. Accordingly, 80 in-house user devices were connected to the CPEn 103 wirelessly and 16 were in the queue, but the in-house user devices 12 were added to the queue of CPEn 103 with the connection waiting number 17. .

After that, the in-house user device 12 does not detect other non-attempt customer in-house devices (CPEs) in the corresponding space, and accordingly enters a connection standby state and stops access attempts for a certain period of time. Referring to FIG. 10, 76-3C-EF-21, which is the identification information of the in-house user device 12, is queue-managed as the connection waiting number 1 in the connection management table of CPE1 101, and the connection management of CPE2 102 In the table, the queue is managed with the connection waiting number 23, and in the connection management table of the CPEn 103, the queue is managed with the connection waiting number 17.

In this state, referring to FIG. 9, the occurrence of an event in which the in-house user device 13 included in the subgroup 1 of the CPE1 101 is disconnected is identified. The CPE1 101 deletes the in-house user device 13 from the list of access devices in its access management table, and thus, there is room for one wireless Internet connection.

One or more in-house user devices located in the corresponding space periodically (e.g., once a second) to request wireless Internet access while periodically (e.g., once a second) around customer premises devices (CPEs), and accordingly, CPE1 101 also requests wireless Internet access from these in-house user devices. Requests for wireless Internet access are continuously received.

Referring to FIG. 10, the CPE1 101 identifies the fact that the identification information of the in-house user equipment having the highest priority according to the connection waiting order in the queue of its connection management table is 76-3C-EF-21. Accordingly, the CPE1 101 allows wireless Internet access to the in-house user equipment 12 having the highest priority, and denies the wireless Internet access request to other in-house user equipments. The in-house user equipment 12 is connected to the CPE1 101 by wireless Internet and joins the subgroup 1.

As described above, when the customer premises device (CPE) allows wireless Internet access to the premises user device, the connection management table must be synchronized to ensure uniformity of management data.

Referring to FIG. 9, CPE1 101 adds an in-house user device 12 to the list of access devices in its own access management table, and sends a device join message (Join_MAC) to the in-house user device 12 to a connection management server ( 200). Upon receiving the device join message (Join_MAC), the access management server 200 transmits a device deletion message (Delete_MAC) for the in-house user device 12 to one or more customer in-house devices (CPE) that are mutually related in the corresponding space. Do it. Upon receiving the device deletion message (Delete_MAC), the customer premises devices CPE1, CPE2, ..., respectively, search the queue of their own connection management table and delete the in-house user device 12.

Referring to FIG. 10, the identification information 76-3C-EF-21 of the in-house user device 12 was queued as the connection waiting number 1 in the connection management table of the CPE1 101, and the 80th item in the connected device list. Was inserted as. Below that, a state in which in-house user devices temporarily denied access to the wireless Internet after requesting a wireless Internet connection to the CPE1 101 are managed in a queue is shown. In addition, the identification information 76-3C-EF-21 of the in-house user equipment 12 was queued as

connection waiting numbers

23 and 17 in the connection management tables of CPE2 102 and CPEn 103, but was deleted.

On the other hand, in FIG. 8, when the in-house user device 12 is denied a wireless Internet connection request from the customer's in-house device (CPE) 101 to 103, it is preferable that a function of checking how much it is in a queue is provided.

As an embodiment, an embedded web server mounted on a customer premises device (CPE) and a web browser of the premises user device 12 may be configured to perform query and response. When the web browser of the in-house user device 12 queries the queue status related to it, the embedded web server of the customer's in-house device (CPE) refers to the queue in the connection management table managed by the corresponding CPE. It is to provide a response with the connection waiting number. To this end, the customer premises equipment (CPE) must reserve some traffic to communicate with the premises user equipment waiting to be connected. Through this, the web browser and the embedded web server communicate periodically, and the web browser display is modified in real time according to the CPE's visitor and queue changes.

In addition, the customer premises device (CPE) collects queue information from other CPEs in the corresponding space and provides it to the in-house user device 12, and the in-house user device 12 is based on this information. It is desirable to display and display a button UI that can be accessed by switching to the shortest CPE. When the user touches and clicks the corresponding button on the terminal screen, the in-house user device 12 is configured to concentrate the wireless Internet access request to the corresponding CPE.

An example of a process in which the in-house user device 12 receives queue information from the CPE1 101 and checks its own waiting state is as follows.

First, the in-house user device 12 transmits a waiting inquiry message to the embedded web server of the CPE1 101.

Upon receiving the queue inquiry message, the CPE1 101 interacts with other CPEs that are related to each other in the corresponding space to collect their respective queue states. The CPE1 101 checks the number of times the in-house user equipment 12 is waiting for connection in each CPE by inquiring the collected queue state, which is referred to as a'connection waiting sequence for each CPE' for convenience of explanation. At this time, the CPE1 101 identifies the customer premises equipment (CPE) indicating the minimum connection waiting order number for the in-house user equipment 12 based on the connection waiting order number for each CPE, which is denoted as'CPE_k' for convenience of explanation. . Then, the CPE1 101 responds to the in-house user device 12 with the CPE-specific connection waiting sequence and CPE_k identification information for the in-house user device 12.

Based on the information provided in this way, the in-house user device 12 displays information on the waiting sequence for each CPE on the device screen. Through this, the user can check his or her standby status. In addition, the in-house user device 12 may display a UI on the device screen of a customer in-house device having the lowest connection waiting order, that is, a network switch connection button UI to CPE_k.

When the user touches and clicks the button and the in-house user device 12 identifies a user operation on the network switch access button UI, the wireless Internet connection is periodically requested by focusing on CPE_k. Accordingly, when there is a room for wireless Internet access in CPE_k, there is a high possibility that the in-house user device 12 immediately succeeds in connecting to the wireless Internet. In order to efficiently perform such an operation, the in-house user device 12 includes a client connection processing unit, which is a dedicated software module.

Meanwhile, the present invention may be implemented in the form of a computer-readable code on a computer-readable nonvolatile recording medium. Various types of storage devices exist as such non-volatile recording media, such as hard disks, SSDs, CD-ROMs, NAS, magnetic tapes, web disks, cloud disks, etc., and codes are distributed and stored in multiple storage devices connected through a network. It can be implemented and executed form. In addition, the present invention may be implemented in the form of a computer program stored in a medium in order to execute a specific procedure by being combined with hardware.
