Description

Remote control system, and method for controlling the same

The present invention relates to a remote control system, and in particular, an administrator remotely manages managed devices anywhere using a data transmission scheme in the form of a mobile oriented-mobile terminated (MO-MT). A control method of a portable remote control system for controlling.

In general, remote control is necessary when the administrator cannot directly control the managed devices.

To this end, portable remote control systems are being used to allow administrators to remotely control managed devices from anywhere.

1 is a view showing the main configuration of a general portable remote control system.

Referring to FIG. 1, a portable remote control system can be largely divided into a manager side and a managed device side, and an infrastructure is a path through which actual data is transmitted for remote control between the manager side and the managed device side. There is (10).

The infrastructure 10, which is a data transmission path, may use a wired network or a mobile communication network that has already been established. If necessary, a new infrastructure may be separately constructed.

Intrastructure Adaptation Part (IAP) (30, 40) is provided on the manager side and the device to be managed, respectively, and the infrastructure adaptation part (IAP) 30, 40 is provided through the infrastructure 10. As a module for using the infrastructure 10, such as transmission, relay, and link connection, the manager side generally includes a human interface part (HIP) 20 to be described later.

In addition to the infrastructure adaptation unit (IAP) 30 on the manager side, a human interface unit (HIP) 20, which is a means for the manager to contact the system, is provided, and in addition to the infrastructure adaptation unit (IAP) 40 on the managed device side. A managing agent part (MAP) 50, which is a means for managing the managed device as a whole, is provided.

In particular, the management agent (MAP) 50 is a device controller (51) for controlling the actual devices by the command input, and a device monitoring unit for detecting abnormal events (monitoring the management target devices ( Device monitor 52).

For example, if a wired or mobile communication network already established as the infrastructure 10 is used, the human interface unit (HIP) 20 and the infrastructure adaptation unit (IAP) 30 on the manager side are one. It becomes a phone, and the administrator issues management commands to the managed devices through an automatic response system (ARS).

However, in the case of constructing and using the new infrastructure 10 separately, the administrator issues a control command through a new interface for the infrastructure 10.

A managed device that can be controlled by such a portable remote control system may be a home automation device, and may be a communication device installed in a place where human traffic is difficult, such as a mountain area, a remote island or a desert area. Other facilities may be. For example, in the case of home automation, home appliances such as television, audio, and video are managed devices. Therefore, there is no restriction of the management target in using the portable remote control system.

The following describes the operation according to the system configuration described above.

The device monitoring unit 52 on the side of the managed device periodically monitors devices to be managed.

Then, if it is detected that an abnormal event occurs in a specific device, the detected event occurrence is transmitted to the manager side through the infrastructure adaptation unit (IAP) 40. For example, if an existing wired network or mobile communication network is used as the infrastructure 10, an alarm is sent to the manager's telephone.

In response to the event occurrence, the manager issues an appropriate control command for the device to be managed through the human interface unit (HIP) 20.

The control command input to the human interface unit (HIP) 20 is transmitted to the management target device side through the infrastructure adaptation unit (IAP) 30.

The management agent (MAP) 50 interprets the control command coming through the infrastructure adaptation unit (IAP) 40 and sends a control command to the corresponding device to be managed, and then the actual control is performed.

The portable remote control system described so far requires security and reliability, and must be implemented to exhibit high efficiency at low cost.

However, conventionally, when a new infrastructure is separately constructed and used without using a wired network or a mobile communication network as an infrastructure, the cost is high and the usable area is limited compared to the existing network. In addition, a human interface unit suitable for the newly constructed infrastructure must be developed separately.

Even if the existing wired network is used as the infrastructure, the remote control system must be connected to the wired network. As a result, remote control of telecommunications equipment or other facilities installed in areas such as mountainous areas, remote islands or desert areas can also be expensive to install.

To reduce the cost of wired line facilities, a mobile communication network can be used. Since the human interface unit is formed based on voice data of an automatic answering system (ARS) as in a wired network, it does not provide an interface such as a string. can not do it. In other words, the ARS can tell you that an abnormal event has now occurred on the managed device because the input must use only ten digits from 0 to 9, but more detailed information about the abnormal event has occurred. Cannot be delivered correctly to

In order to solve this limitation, there is a method of using a short message service (SMS) through a mobile communication network, but this short message service (SMS) has a security mechanism because there is no mechanism for security. Since there is no retransmission and confirmation procedure, it is also less reliable to send control commands.

More precisely, a control command of a user who does not have administrative authority over the managed devices may be accepted, and the command may not be delivered to the managed device side even if an administrator gives a control command.

Accordingly, an object of the present invention is to solve the above problems, by using a mobile communication network as an infrastructure, and by transmitting a short message of the MO-MT type through a mobile communication network using a short message service (SMS) Provided are a portable remote control system and a method of controlling the same, which delivers an abnormal event or control command generated more specifically.

Another object to solve the above problems is presently generated by using the Wireless Application Protocol (hereinafter referred to as WAP) and transmitting MO-MT data on this WAP with a security mechanism applied. The present invention provides a portable remote control system and a control method thereof for reliably delivering abnormal events or control commands.

A feature of the remote control method according to the present invention for achieving the above object, according to the detection of the occurrence of the event in a specific device to be managed, to configure the detected event occurrence in the form of a short message to deliver to the administrator side terminal And transmitting, by the manager terminal receiving the short message, a control command for the generated event in a short message form to the terminal to be managed, and the terminal to be managed by the terminal to be managed. Interpreting the message to control the device on which the event occurred.

Preferably, the short message is delivered to the opposite terminal through the mobile communication network providing the short message service.

In addition, another feature of the remote control method according to the present invention for achieving the above object is, as the occurrence of the event is detected in a specific device to be managed, by the wireless markup language (WML) Configuring the WML data and transmitting the WML data to a manager-side terminal; and receiving, by the manager-side terminal, the WML data, the control command for the generated event in the form of WML data and transmitting the WML data to a terminal to be managed; And controlling, by the terminal to be managed by the device-side device, the transmitted WML data to control the device in which the event is generated.

Preferably, the WML data is transmitted to the opposite terminal through the mobile communication network to which the WAP is applied.

Also, WML data transmitted to the manager terminal and the management device terminal is inserted and transmitted by a security mechanism, respectively, and the WML data transmitted to the manager terminal and the management device terminal are requested by the other party. Is retransmitted accordingly.

Hereinafter, a preferred embodiment of a portable remote control system and a control method thereof according to the present invention will be described with reference to the accompanying drawings.

In the present invention, a control command of an administrator or an abnormal event currently occurring is transmitted in a short message of MO-MT type, or data generated by a wireless markup language (hereinafter, abbreviated as WML) is MO-MT type. Is sent to.

Here, the MO-MT is a data transmission form transmitted by the communication terminal and received by the communication terminal.

2 is a view showing the main configuration of a portable remote control system using a short message transmission of the MO-MT type of the present invention.

Referring to FIG. 2, the portable remote control system according to the present invention can be largely divided into a manager side and a managed device side, and a path through which an actual short message is transmitted for remote control between the manager side and the managed device side is provided. There is an intrastructure 100.

The infrastructure 100, which is a data transmission path, uses a mobile communication network that is already established, and a short message is transmitted through the mobile communication network.

On the manager side and the managed device side, infrastructure adaptation units (IAPs) 120 and 130 are provided, respectively. The infrastructure adaptation units (IAPs) 120 and 130 may transmit short messages through the infrastructure 100, relay and link connections, and the like. As a module for using the infrastructure 100 as described above, in general, the manager side includes a human interface unit (HIP) 110, which will be described later, to become a communication terminal. This communication terminal uses an existing general communication terminal as it is.

In addition to the infrastructure adaptation unit (IAP) 120, the manager side includes a human interface unit (HIP) 110, which is a means for the manager to contact the system. The human interface unit (HIP) 110 is a module in which a short message is input or output.

In addition to the infrastructure adaptation unit (IAP) 130, a management agency (MAP) 140, which is a means for managing the management device as a whole, is also provided on the managed device side.

In particular, the management agent (MAP) 140 is a device controller (141) for controlling the actual devices by the input command, and a device monitoring unit for detecting abnormal events (monitoring the management target devices ( Device monitor 142.

What is unique in the present invention is that a conventional communication terminal is used as it is as a communication terminal of the manager side, but a communication terminal in which a short message service function is added to the general communication function is used as the management target device side. In addition, infrastructure adaptation units (IAPs) 120 and 130 provided on the manager side and the device to be managed are defined by four layers of protocols for short message transmission.

The protocols of these four layers are SMS Teleservice Layer (121,131), SMS Transport Layer (122,132), SMS Relay Layer (123,133), Link Layer (Link) Layer) 124,134.

The SMS communication service layers 121 and 131 define a short message service, and the SMS transport layers 122 and 132 accurately deliver a short message to be transmitted to a desired destination according to the short message service defined by the SMS communication service layers 121 and 131. Hierarchy.

The SMS relay layers 123 and 133 are layers that check the short message length to make it an appropriate message format and provide a channel over which this message will be sent. The link layers 124 and 134 interconnect the channels provided by the SMS relay layers 123 and 133 with the counterpart, and are layers that maintain or release the connection.

The following describes the operation according to the system configuration described above.

The device monitoring unit 142 of the device to be managed periodically monitors devices to be managed.

Thereafter, if it is detected that an abnormal event occurs in a specific device, the detected event occurrence is transmitted to the manager through the infrastructure adaptation unit (IAP) 130.

The infrastructure adaptation unit (IAP) 130 forms the event content in the form of a short message so that the generated event content is delivered to the administrator through the short message service.

The SMS transport layer 132 inserts the source address and the destination address into the short message to be sent, and the SMS relay layer 133 examines the short message length to form an appropriate message format and sets up a call to the channel to which the message is to be sent. do.

The link layer 134 connects the channel set up with the partner link layer 124, and the manager side SMS relay layer 123 receives the short message through the channel set up as the call is connected to the SMS transport layer 122. do.

The manager side SMS transport layer 122 analyzes the received short message to find the source address and the destination address, and then the message content is transmitted to the manager through the human interface unit (HIP) 110.

The administrator who receives the event occurrence through the short message service again issues an appropriate control command to the device to be managed through the human interface unit (HIP) 110.

The control command inputted to the human interface unit (HIP) 110 is transmitted to the managed device side through the infrastructure adaptation unit (IAP) 120. The process of transmitting the control command is the same as the above-described event transmission process. It is transmitted to the management agency (MAP) 140 via.

Thereafter, the management agent (MAP) 140 interprets the short message coming through the infrastructure adaptation unit (IAP) 130 and sends a control command to the corresponding device to be managed, and then the actual control is performed.

In the present invention, the generated event and control command can be represented by numbers and letters by using the short message transmission in the MO-MT format described so far.

In addition, the present invention also provides a remote control procedure for transmitting the event content or control command generated by the WML in the form of MO-MT.

3 is a view showing the main configuration of a portable remote control system using the MO-MT data transmission on the WAP of the present invention.

Referring to FIG. 3, another portable remote control system according to the present invention can also be largely divided into a manager side and a managed device side, and actual WML data is transmitted for remote control between the manager side and the managed device side. There is an infrastructure 200 as a passageway.

The infrastructure 200, which is a WML data transmission path, uses a mobile communication network that is already established, and WAP is applied.

On the manager side and the managed device side, infrastructure adaptation units (IAPs) 220 and 230 are provided, respectively. The infrastructure adaptation units (IAPs) 220 and 230 may transmit WML data through the infrastructure 200, relay and link connections, and the like. As a module for using the infrastructure 200 as described above, in general, the manager side includes a WML browser 210 as described later to become a communication terminal. This communication terminal uses an existing general communication terminal as it is.

In addition to the infrastructure adaptation unit (IAP) 220 on the manager side is provided with a WML browser 210 in charge of the human interface (human interface) as a means for the administrator to contact the system. This WML browser 210 is a module into which WML data is input or output.

In addition to the infrastructure adaptation unit (IAP) 230, a management agent unit (MAP) 240, which is a means for managing the managed device as a whole, is also provided on the managed device side.

In particular, the management agent (MAP) 240 is a device controller (241) for controlling the actual devices by the input command, and a device monitoring unit for detecting abnormal events (monitoring the management target devices ( Device monitor) 242.

What is unique in the present invention is that a conventional communication terminal is used as it is as a communication terminal of the manager side, but a communication terminal in which a WML data transmission service function is added to the general communication function is used as the management target device side. In addition, infrastructure adaptation units (IAPs) 220 and 230 provided on the manager side and the managed device side are defined by four layers of protocols for WML data transmission.

The protocols of these four layers include the Wireless Session Protocol layer (WSP) (221,231), the Wireless Transaction Protocol layer (WTP) (222,232), and the wireless transport security protocol layer (WTLS: Wireless). Transport Layer Security (223,233), and Wireless Datagram Protocol layer (WDP: Wireless Datagram Protocol layer) (224,234).

The wireless session protocol layers 221 and 231 provide a basic logical channel for transmitting WML data. The radio protocol layers 222 and 232 are layers for retransmitting the WML data when the WML data to be transmitted is lost to the desired destination and is lost during transmission.

The radio transmission security protocol layers 223 and 233 are layers to which a security mechanism is applied. In the present invention, all WML data to be transmitted have security through this layer.

The last wireless datagram protocol layers 224 and 234 are layers for creating and transmitting datagrams containing information necessary for communication path designation between the manager side and the managed device side. This eliminates the necessity of establishing a circuit between communication terminals for transmitting WML data.

The following describes the operation according to the system configuration described above.

The device monitoring unit 242 on the side of the managed device periodically monitors devices to be managed.

Thereafter, if it is detected that an abnormal event occurs in a specific device, the detected event occurrence is transmitted to the manager through the infrastructure adaptation unit (IAP) 230.

The infrastructure adaptation unit (IAP) 230 makes the generated event content in the form of WML data.

When a basic logical communication path for WML data transmission is provided by the wireless session protocol layer 231 on the side of the managed device, a password is inserted into the WML data by the security mechanism of the wireless transmission security protocol layer 233.

After that, the wireless datagram protocol layer 234 includes data necessary for communication path designation between the manager side and the managed device side in the WML data inserted with the encryption code, to create a datagram, and the manager through the infrastructure 200. Deliver to the side.

The manager-side wireless datagram protocol layer 224 receives the datagram corresponding to it, and transmits the corresponding WML data to the wireless transmission security protocol layer 223.

The manager side wireless transmission security protocol layer 223 deletes the password from the received data, and then the WML data is transmitted to the manager through the WML browser 210.

The administrator, who receives the event occurrence as WML data, issues an appropriate control command for the device to be managed again through the WML browser 210.

The control command input to the WML browser 210 is transmitted to the management device side through the infrastructure adaptation unit (IAP) 220, and the management agency of the control command is subjected to the same procedure as the event transmission process. (MAP) 240 is passed.

Thereafter, the management agent (MAP) 240 analyzes the WML data coming through the infrastructure adaptation unit (IAP) 230 and sends a control command to the corresponding device to be managed, and then the actual control is performed.

However, in the remote control using the WML data transmission of the MO-MT type, the manager side communication terminal or the management target device side communication terminal has a server function for transmitting a response to the transmitted event or control command.

Therefore, in the present invention, when there is a response that the event information currently generated from the administrator is not normally received or a response that the current control command is not normally received from the managed device side, the WML data to be transmitted is correctly delivered to the desired destination. If not, it is determined that it is lost in the middle of transmission, and the WML data is retransmitted by the radio processing protocol layers 222 and 232.

In the present invention, the generated event and control command can be expressed not only in numbers and letters but also in pictures by using WML data transmission in the MO-MT form described so far.

As described above, according to the portable remote control system and the control method according to the present invention has the following advantages.

First, since the mobile communication network is already built as an infrastructure, there is no need to build a new infrastructure, and thus the cost added to the infrastructure construction is also saved.

Second, when the event or control command generated by using the short message is delivered to the other side, more accurate information can be delivered than before, and when WML data is used, not only accurate information delivery but also security by applying a security mechanism and Reliable information transmission by data retransmission can be added.

Third, the present invention can be applied to various mobile communication systems (CDMA, GSM, IMT-2000, etc.) using various local service networks.
