Description

Communication service providing system and control method

The present invention relates to a communication service providing system and a control method thereof, and more particularly, to a communication service providing system and a method of controlling the same, in which an AP providing a short range wireless communication service detects a failure in communication with an APC.

Recent developments in communication technology have allowed each communication terminal to be not only limited to wired communication but also wireless communication.

In particular, the development of short-range wireless communication is prominent, and not only a terminal in which wired communication has traditionally been basic, such as a computer, but also a portable terminal that performs communication through a base station is configured to enable short-range wireless communication.

In order to enable short-range wireless communication, an access point (AP) that communicates through a wireless section with each terminal must be present.

In general, a single access point may be provided in a home, but a plurality of APs may be provided in a public library, a coffee shop, or a crowded public place, and in this case, to control a plurality of APs. Additional APCs may be needed.

The APC is a device that processes user authentication and controls an AP so that a communication connection is made or not to a corresponding communication terminal according to user authentication.

As such, in a system in which a plurality of APs are connected to the APC, at least one of the plurality of APs may not normally communicate with the APC due to various problems on the network.

For example, an APC may not receive data transmitted by a specific AP due to a failure in a wired cable between a specific AP and an APC section.

However, APC has no way of distinguishing whether or not data is not received due to an error in a cable with a specific AP or data is not received because there is no communication through the specific AP itself.

1 is a schematic structural diagram of a communication service providing system according to an embodiment of the present invention;

2 to 3 are control flowcharts of a communication service providing system according to an embodiment of the present invention.

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

Hereinafter, each embodiment according to the present invention is only one example to help understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention may be composed of a combination of at least one or more of individual configurations, individual functions, or individual steps included in each embodiment.

In the communication service providing system according to an exemplary embodiment of the present invention, a plurality of APs (ACCESS POINT) 210, 220, 230 communicating with the communication terminal 300, and APCs (ACCESS POINT CONTROLLER) communicating with each of the plurality of

APs

210, 220, 230 ( 100), including.

The communication terminal 300 is a terminal having a short range wireless LAN communication function, and may correspond to, for example, a portable terminal device having a short range wireless communication module such as a mobile phone or a smart phone as well as a personal computer such as a laptop.

The communication terminal 300 may establish a communication channel with the

APs

210, 220, and 230 to access an external communication network such as the Internet.

AP (210,220,230) is to provide a wireless communication service to the communication terminal 300, the technology for communicating through the wireless section of the AP (210, 220, 230) and the communication terminal 300 corresponds to a known technology, so a more detailed description Omit. However, the

APs

210, 220, and 230 may be, for example, devices that provide a short range wireless LAN service to the communication terminal 300, or may correspond to wireless base stations that provide mobile communication services as part of a mobile communication network. That is, the present invention is not necessarily limited to the WLAN environment.

AP (210,220,230) (hereinafter referred to as the 'error detection AP 210') that detects the abnormality in the connection state with the APC 100 of the plurality of AP (210,220,230) performs a function to generate and send a warning notification signal .

For example, the

APs

210, 220, and 230 transmit an authentication request signal to the APC 100 for authentication, etc., in response to a request of the communication terminal 300, and respond to the authentication request signal within a preset time from the APC 100. If is not received, the AP (210, 220, 230) is to detect that there is an error in the connection state with the APC (100).

This situation may occur when an error occurs in the wired communication cable between the

APs

210, 220, 230 and the APC 100.

In this embodiment, the communication between the AP (210,220,230) and the APC 100 is made by wire, and the wireless communication between the AP (210,220,230) is an example, respectively, an error in the wire between the AP (210,220,230) and APC (100) In this case, the abnormality detection AP 210 may generate a warning notification signal and transmit the warning notification signal.

The alert notification signal may include device information for specifying the abnormality detection AP 210 such as the SSID information of the abnormality detection AP 210.

Also, the abnormality detection AP 210 may receive a reset control signal from another AP 220, and may perform a device reset according to the reset control signal. Here, the device reset may mean a device reboot.

Meanwhile, the warning notification signal transmitted by the abnormal detection AP 210 wirelessly may be received by another AP 220, and the

APs

210, 220, and 230 that receive the warning notification signal (hereinafter referred to as 'other AP 220'). ) May transmit a warning notification message to the APC 100.

That is, the other AP 220 informs the APC 100 that the abnormality detection AP 210 cannot communicate with the APC 100 through the wired section.

The warning notification message transmitted from the other AP 220 to the APC 100 may include SSID (SERVICE SET IDENTIFIER) information of the abnormality detection AP 210 included in the warning notification signal of the abnormality detection AP 210.

In addition, the other AP 220 may receive a reset control transfer signal from the APC 100, as will be described later, in this case also performs a function of transmitting the reset control signal to the abnormal detection AP (210).

The APC 100 performs an authentication process for the communication terminal 300 connected to each of the

APs

210, 220, and 230.

For example, the APC 100 may determine whether the user is a registered user by using an IP address, a mac address, a login ID, and a password received from the communication terminal 300. Since the communication process related to authentication of the APC 100 and the

APs

210, 220, and 230, respectively, is only known technology, a detailed description thereof will be omitted.

In addition, the APC 100 performs a function of determining whether a function failure of each

AP

210, 220, 230 occurs, in particular, whether a communication failure occurs with each

AP

210, 220, 230.

In detail, when the APC 100 receives a warning notification message from another AP 220, a failure occurs by using SSID (Service Set Identifier) information as an example of device information of the abnormality detection AP 210 included in the warning notification message.

APs

210, 220, and 230 may be determined.

In this case, the APC 100 transmits a failure confirmation signal to the

APs

210, 220, 230, that is, the abnormality detection AP 210 corresponding to the SSID information included in the alert notification message, and responds to the failure confirmation signal within a preset time. If no abnormality is detected from the AP 210, a failure of the abnormal detection AP 210 (for example, a failure in the network with the abnormal detection AP 210) may be determined.

When the failure detection of the abnormality detection AP 210 is determined in this way, the APC 100 may transmit a reset control transfer signal to the other AP 220. This is to allow the other AP 220 to transmit the reset control signal to the abnormality detection AP 210 as described above.

The APC 100 may generate an alarm signal when it is determined that a failure occurs. For example, the APC 100 may transmit a warning message in the form of a text message using a registered user terminal phone number, or may transmit a warning message to a connected manager terminal. It may push or output a warning message to a self-contained display device.

Hereinafter, a control flow of a communication service providing system according to an embodiment of the present invention will be described with reference to FIGS. 2 to 3.

2 illustrates a process of informing the APC 100 of the abnormal state of connection through the other AP 220 when the abnormality detection AP 210 detects an abnormal state of the connection with the APC 100.

First, when there is a request from the communication terminal 300, the AP 210 generates an authentication request signal and transmits it to the APC 100 (step S1).

If an authentication response corresponding to the authentication request signal is received from the APC 100 within the preset time (step S3), the abnormality detection AP 210 performs normal processing (step S5). Here, normal processing means controlling the authenticated communication terminal 300 to be connected to an external communication network.

If the authentication response is not received from the APC 100 within the preset time (step S3), the abnormality detection AP 210 determines that a problem has occurred in the wired network with the APC 100 (step S7).

In this case, the abnormality detection AP 210 extracts its SSID (step S9) and transmits a warning alarm signal including the extracted SSID to the wireless section so as to be received by another AP 220 (step S11).

Here, the warning alarm signal may be a signal that may be received by another specific AP, or may be a signal that any AP may receive.

The other AP 220 receiving the warning alarm signal of the abnormality detection AP 210 extracts the SSID of the abnormality detection AP 210 from the warning alarm signal (step S13), and generates a warning notification message including the extracted SSID. Delivering to the APC 100 via the wired section (step S15).

Accordingly, the APC 100 receiving the warning notification message may determine that there is an error in connection with the abnormality detection AP 210.

3 is a diagram illustrating a process performed by the APC 100 after receiving an alert notification message from another AP 220. For reference, FIG. 3 further includes a process of additionally checking the APC 100 without determining that a failure has occurred on the network with the abnormality detecting AP 210 at the time when the APC 100 receives the warning notification message from the other AP 220.

Upon receiving the warning notification message, the APC 100 may transmit a failure confirmation signal to the abnormality detection AP 210 by referring to the SSID information included in the warning notification message (step S21).

When the response signal corresponding to the failure confirmation signal is received from the abnormality detection AP 210 within the preset time (step S23), the APC 100 performs normal processing (step S25). In this case, the normal processing includes determining that the network failure is temporary and performing no further processing related to the failure.

If the response signal corresponding to the failure confirmation signal is not received from the abnormality detection AP 210 within the preset time (step S23), the APC 100 determines the occurrence of the failure (step S27), and generates a reset control transfer signal. (Step S29) The transfer to the other AP 220 through the wired network (step S31).

The other AP 220 transmits the reset control signal to the abnormality detection AP 210 through the wireless communication section according to the reset control transfer signal of the APC 100 (step S33).

The abnormality detection AP 210 performs a reset process according to a reset control signal received from another AP 220 (step S35).

Meanwhile, the APC 100 may generate an alarm signal and transmit a failure to the wired communication network between the abnormal detection AP 210 and the APC 100 to an administrator or the like (step S37).

According to the present invention, when a failure occurs in a wired section between a specific AP and the APC, the APC can quickly check this and automatically perform a separate action according to the failure.
