Description

Protocol for event driven messaging of home network devices

The present invention relates to a method for processing a home network device event protocol, and more particularly, to a method for processing a home network device event protocol when an event occurs in a device of a home network service.

Recently, due to the wide spread of the Internet and the development of communication technology, the field of home network and home automation for connection and utilization of various electric / electronic devices and communication devices in the home or office has been attracting attention.

Conventional home automation is mainly made up of videophones and interphones to check visitors, but various functions including gas leaks and fire alarms are gradually being added. However, such a simple set of functions is not really home automation. In other words, not only some devices are controlled and monitored, but they are configured as a network to control, monitor, and operate all the devices connected to the network, and computer-related devices are configured as data networks to the external Internet. Making the connection available is truly home automation.

In the home network field, standardization and technology development are being actively performed for each communication method such as wireless LAN, Bluetooth, and IrDA communication using a wired LAN such as HomePNA or IEEE1394, and HomeRF. In the field of home automation, so-called Lonwork-based building automation devices are attracting attention.

Integrated standardization of home network and home automation related technologies is still inadequate, and home servers required to perform comprehensive home automation control that can support various protocols and support remote control and home control using wired / wireless communication line or Internet network. The development of the home gateway is also in progress.

On the other hand, corresponding to various communication protocols, a control device capable of integrated management of devices (electric appliances) distributed in the home has also been developed. That is, a control device for a home network that can support all communication protocols such as IEEE1394, USB, IrDA, X-10, and Lonwork is being developed.

However, there is no standardization of an interworking protocol between the HNSN serving as a central server and the RG installed in the home, which is provided for the home network or the home automation as described above.

An object of the present invention is to provide a method for processing a home network device event protocol for processing an event occurring in a device of a home network service.

As a technical idea for achieving the above object of the present invention, the present invention is connected to a mobile network and the central server for transmitting the control and control state of the device, the central server (HNSN) and the network is connected through a plurality of devices Applied to a system comprising a gateway (RG) to which is connected, the home network device event protocol processing method of the present invention comprises: a first step of receiving, at the central server, an event reception request message sent by a user; Delivering the received event reception request message to the gateway, wherein the gateway forwards an event reception request message to a device; Transmitting an event reception response message from the device to the gateway, wherein the gateway forwards an event reception response message to a central server; A fourth step of delivering an event occurrence message generated by the device to a central server through a gateway; And a fifth step of transmitting an event occurrence response message from the central server to the corresponding device via a gateway.

At this time, before the first step, the central server further recognizes the equipment connected to the gateway using the UPnP protocol, and receives the device configuration file and the service configuration file of the device at the central server. do.

In addition, after the fourth step, the generated event is databased, it is preferable to deliver the event message from the central server to the user terminal using a mobile network.

And, after the fifth step, if the user wants to perform the event rejection, receiving the event rejection request message sent by the user at the central server; Delivering the received event rejection request message to the gateway, the gateway forwarding an event rejection request message to a device; And forwarding an event rejection response message from the device to the gateway, wherein the gateway further forwards the event rejection response message to the central server.

Meanwhile, the protocol stack between the central server, the gateway, and the device uses GENA (HTTP) based on TCP / IP.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a schematic view showing the overall system of the present invention. As shown in FIG. 1, the present invention is largely composed of an area for generating a control / control state signal, a network for transmitting and receiving it, an area for performing event management, the Internet, and an area installed in a home. In particular, the present invention relates to a protocol relating to interworking between an area for performing the event management and an area installed in a home.

The area for generating the control / control state signal may use a mobile phone (cdma2000 1x Ev-Do, WCDMA) 10 that generates and transmits a control / control state signal, or provides a control / control state signal. A notebook (WLAN) 12 or a PDA (WCDMA, WLAN) 14 or the like which generate and transmit and receive may be used.

The network that transmits the data transmitted from the mobile phone 10, the notebook 12, and the PDA 14 or the data transmitted from the HNSN 22 receives a control signal transmitted from the mobile phone 10 to receive a network. Or a base station 16 which transmits the transmitted control status signal to the mobile phone 10, and receives a control signal transmitted from the notebook 12 or the PDA 14 to the network or transmits the received control signal. An access point (AP) 18 that transmits a control status signal to the notebook 12 or PDA 14 and a signal transmitted from the base station 16 and the access point 18 in a wired or wireless form to receive the event; It is composed of a mobile network 20 for transmitting to the area for management.

The event management area is a home network serving node (HNSN) 22 performing a central server function. The HNSN 22 is connected to the Internet 24 to perform event management of an area installed in the home. The configuration thereof will be described later in detail.

The area installed in the home may configure all data networks capable of performing control, monitoring, and interlocking operations by interworking with data gateways (RGs) 26 connected to the Internet 24. These devices consist of home appliances, computers, security equipment, remote meter reading equipment, and remote medical equipment. In the reference numerals, the device will be given the same reference numerals for convenience of description.

The present invention relates to the interworking protocol between the HNSN 22 and the RG 26 among the entire system configured as described above, and describes the HNSN 22 that plays an important role.

2 is a configuration diagram of the HNSN. As shown in FIG. 2, the HNSN 22 is largely composed of a user application server 221, a DB 222 (Data Base), an HnsnRgIF 223, and an HnsnUPnP 224.

The user application server 221 receives the control / control state signal transmitted from the mobile network 20, processes it with the corresponding protocol, and transmits the control / control state signal processed by the corresponding protocol to the DB 222. In addition, it is delivered to the HnsnUPnP (224) or directly to the RG (26). At this time, the messages transmitted to the HnsnUPnP 224 are messages regarding a request and a response regarding device recognition, configuration file maintenance, device control and status monitoring, and device event control.

The DB 222 updates and stores data in response to signals transmitted from the user application server 221, the HnsnRgIF 223, and the HnsnUPnP 224, and performs a function of reading stored data.

The HnsnRgIF 223 (HNSN-RG I / F) provides an interface for registration, authentication, and connection management using SOAP, and performs a database operation of updating the DB 222. Its protocol stack is shown in FIG.

The HnsnUPnP 224 (HNSN UPnP) performs device recognition using SSDP / GENA, maintains configuration files using HTTP, monitors device control and status using SOAP, and controls device events using GENA. .

The UPnP is a protocol for exchanging UI and control information between digital devices based on HTML (Hyper Text Markup Language) and XML (Extensible Markup Language) widely used in the Internet 24, as shown in FIG. (Transmission Control Protocol), Internet Protocol (IP), User Datagram Protocol (UDP), General Event Notification Architecture (GENA), Simple Service Discovery Protocol (SSDP), and Simple Object Access Protocol (SOAP).

As such, the HNSN 22 provides a function to control events occurring in the device 28 managed by the home RG 26. The user can control the event reception of the device, and when the event occurs, it can be confirmed in real time not only on the web screen but also on the mobile phone 10, notebook 12 and PDA (14).

The operation between the HNSN, RG and the device in detail using the system configured as described above is as follows.

5 is a control flowchart of HNSN and RG and devices. As shown in FIG. 5, discovery and description perform a process defined in the UPnP protocol. That is, each device is recognized through the RG 26 in the discovery process of the HNSN 22 (S1), and a device configuration file and a service configuration file of each device in the description process. File) (S2).

As such, when the user selects an event receiving command from the user application while the recognition and setting process is completed, the corresponding GENA request message is transmitted to the HNSN 22.

The HNSN 22 forwards the received GENA request message to the RG 26 (S3), and the RG 26 forwards the GENA request message to the corresponding device 28 (S4). Accordingly, the GENA response message from the device 28 is transmitted to the RG 26 (S5), and the GENA response message from the RG 26 is transmitted to the user application server 221 (S6).

Thereafter, the event occurring in the device 28 transmits the GENA request message to the HNSN 22 via the RG 26 (S7 to S8). This forwarded event is stored in the DB 222 and directly informs the user terminal 10, 12, 14. The HNSN 22 transmits the GENA response message of the event to the device 28 through the RG 26 (S9 to S10).

On the other hand, when the user selects the event rejection command in the application, the corresponding GENA request message is transmitted to the HNSN 22.

In response, the HNSN 22 forwards the received GENA request message to the RG 26 and the device 28 (S11 to S12), and sends the GENA response message from the device 28 and the RG 26 to the user application server 221. (S13 to S14). Thereafter, events occurring in the device 28 are not delivered to the HNSN 22.

The protocol stack for this uses GENA (HTTP) over TCP / IP.

The present invention is not limited to the above-described embodiments, and it will be apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.

As described above, in the home network device event protocol processing method according to the present invention, when an event (gas leak, door open, etc.) occurs in a device in a house by a central server, the user can be notified of the situation and control. In addition, it is possible to prevent accidents that can be enlarged in advance.
