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.

The present invention is to solve the above problems, an object of the present invention is the registration, authentication and authentication of the RG to perform the registration, authentication and access management of the RG in conjunction with the central server (HNSN) and RG (regidential gateway) installed in the home It provides a method for access management protocol.

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 Is applied to a system including a gateway (RG) to which the connection is made. The method for registration, authentication, and connection management protocol of the RG of the present invention includes a registration request message including an ID, a password, and an IP at the gateway. Transmitting to; Databaseting a registration request message input through an interface of the central server; Transmitting, at the central server, a registration response message including its IP and port to the gateway; If the registration is made, transmitting the authentication request message including the ID, password, and IP to the central server every set time at the gateway; And updating the database by updating the authentication request message input through the interface of the central server.

At this time, if the gateway does not send an authentication request message, error processing or failure processing is performed. If the gateway is deleted, service stop request and response messages are transmitted and received, and the information of the corresponding user is updated by a database.

Meanwhile, the protocol stack between the central server and the gateway uses SOAP (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 an area for generating a control / control state signal, a network for transmitting and receiving it, an area for performing registration, authentication, and connection management, the Internet, and an area installed in the home. It consists of. In particular, the present invention relates to a protocol relating to interworking between an area for performing the registration, authentication, and access 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 the signal transmitted from the base station 16 and the access point 18 in a wired or wireless manner to receive the registration; It consists of a mobile network 20 to transmit to the area for performing authentication, access management.

The area for performing registration, authentication, and access management is a home network serving node (HNSN) 22 performing a central server function. The HNSN 22 is connected to the Internet 24 to perform registration, authentication, and access management of the 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 registration, authentication, and management functions of the home RG 26. In order to control devices below the RG 26 in the HNSN 22, the network information (IP and Port), and this information is managed by the HNSN 22 through the RG 26 registration process. In addition, the RG 26 continuously sends a message after registration, and the HNSN 22 checks the current state of the RG 26. In addition, all messages between the HNSN 22 and the RG 26 include data for authentication, so that messages from the unauthenticated HNSN 22 or messages from the unauthenticated RG 26 are rejected.

The registration, authentication, and access management operations of the RG using the system configured as described above are described in detail.

5 is a control flow diagram between HNSN and RG. As illustrated in FIG. 5, the RG 26 has information such as ID, password, and IP, and sends a message requesting registration to the HNSN 22 (S1).

<ID> Tom </ ID>

<Password> Tom111 </ Password>

<IP> 123.456.789.1 </ IP>

The message requesting this registration is delivered to the DB 222 through the HnsnRgIF 223 of the HNSN 22 to change the user information database.

The HNSN 22 has its network information (IP and port) and sends a registration response to the RG 26 (S2).

<ns: RegisterResponse>

<hnsnSSDPUR> 234.456.7.8:8001 </ hnsnSSDPUR>

<hnsnGENAUR> 234.456.7.8:8002 </ hnsnGENAUR>

<Result> 1 </ Result>

</ ns: RegisterResponse>

After successful registration, the RG 26 then informs the HNSN 22 of the status by sending an Alive message with information such as ID, password and IP every set time, for example, every minute.

<ID> Tom </ ID>

<Password> Tom111 </ Password>

<IP> 123.456.789.1 </ IP>

HNSN 22 stores the information in the user information DB 222 and updates it.

On the other hand, when the authentication message is not sent every minute, the HNSN 22 determines that a failure has occurred (S3 to S4).

If it is determined that the RG 26 is deleted, that is, the service is no longer performed, the service stop message (Bye) is sent, and the HNSN 22 changes the user information (S5 to S6).

The protocol stack for this uses SOAP (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, the method for registration, authentication, and access management protocol of RG according to the present invention can provide efficient home network service by performing efficient registration, authentication, and access management of RG.
