The present invention relates to a remote software upgrade method in a home network serving node (HNSN). More specifically, the present invention relates to a remote software upgrade method for remotely controlling software updates of a residential gateway (RG) linked to an HNSN system.

The network generally includes a communication link and various devices having communication capabilities connected to the communication link. Such devices include computers, peripherals, routers, storage devices, and electrical appliances having a communication interface with a processor. An example of a network is a home home network with various devices interconnected.

A typical home may include a variety of devices, including personal computers and home devices typically found in homes. The term 'device' typically includes logical devices or other devices having functionality and the ability to exchange data, and may include general purpose computers as well as all home devices.

Household devices may include security systems, theater equipment, televisions, VCRs, stereo equipment, and direct broadcast satellite services (DBSS) known as digital satellite services (DSS), sprinkler systems, lighting systems, Electronic devices such as microwaves, dishwashers, ovens / stoves, washing machines / dryers and processing systems in automobiles.

In general, home devices are used to perform a task of raising the type and standard of living of a homeowner. A dishwasher, for example, performs the task of cleaning dirty dishes and saves homeowners the trouble of having to wash their own dishes. VCRs record TV programs so that homeowners can watch specific programs later. Security systems can protect homeowners' valuables and relieve homeowners of fear of unwanted intrusions.

Household devices, such as home theater equipment, are often controlled using a single common control unit called a remote control device. This single common control unit allows homeowners to control and command a variety of different home devices using a single interface. That is, many producers have developed control units for controlling and commanding household devices from a single interface.

One disadvantage associated with using a remote control unit to command and control home devices is that it provides static command logic to control and command each home device. Therefore, a particular remote control unit can only control and command home devices including the necessary control and command logic.

For example, if the remote control unit includes logic for controlling television (TV), video cassette recorder (VCR), and digital video device (DVD) but does not include logic for compact disc (CD) unit, The remote control device cannot be used to command and control the CD unit. Moreover, as new home appliances are developed, the remote control unit will not be able to control and command new home appliances that require control and command logic that was not known at the time the remote control unit was developed.

Moreover, the remote control unit can only be used to command and control home devices in a single area of the remote control unit. Therefore, the user cannot use the remote control unit from a single area in the home to control and command home devices that are interconnected but located in separate areas of the home.

Another disadvantage associated with using a remote control unit is that the known remote control unit is unable to control a number of different types of devices, and that a number of other capabilities have different capabilities to communicate with each other to complete a task or provide a service. You can't control the devices. Moreover, conventional network systems do not provide a mechanism for software applications in other network devices that automatically communicate with each other to accomplish a task without a user's direct command.

Currently used networks use a centralized user interface (eg, a centralized user interface) without the ability to provide user interface and control of devices and services connected to other different networks (eg, the Internet). 1394 only allows communication and control of the devices connected to it.

In addition, currently used networks do not allow remote communication and control with devices connected to the network (eg, 1394 home network) via other different networks (eg, the Internet).

This prevents remote upgrade of data (software) for various gateways and devices connected to the network.

Accordingly, a need exists for a technology that can provide dynamic control and command of gateways and devices connected to a home network.

The present invention is to solve the above problems, the present invention is a remote software upgrade to remotely control the software update for the RG (Residential Gateway, RG) or the device associated with the HNSN system linked to it The purpose is to provide a method.

As the technical idea for achieving the above object of the present invention

A home network serving node (HNDN) for providing home network services; An indoor gateway (RG) having a plurality of devices used in the home and serving as a gateway; In the Internet-based remote software upgrade method for wireless Internet access between the home network serving node (HNDN) and the home gateway (RG),

1, the present invention provides a user terminal 10 which is a mobile communication terminal including a PCS phone, a cellular phone, CDMA 2000, IMT-2000, W-CDMA and the like; A base station (BTS) 20 which enables wireless communication with the user terminal 10 and transmits and receives a signal to and from a connected base station controller (BSC) 30 located in a transmission path; A packet data serving node (PDSN) 40 for connecting a network 50 with the base station controller 30; An HNDN 100 including an application server 110 for processing a request of each terminal and providing a home network service; An internet 60 having a communication network for wireless internet access; And a plurality of devices 210 including various home appliances, lighting systems, and security systems used in the home, and remotely updating software of each device and rebooting the gateway. It is composed of RG (200) which is an indoor gateway that performs the operation.

FIG. 2 is a detailed configuration diagram of a home network serving node (HNSN) system, which includes an application server 110 interworking with a network 50 including a web / WAP and a virtual machine (VM); HnsnUPnP 120 serving as a home network middleware; A user / device information DB (130); And HnsnRgIF 140 serving as a home network interface. At this time, the HnsnUPnP 120 and HnsnRgIF 140 are linked with the RG 200.

The application server 110 receives and processes the request of each terminal, and converts the response from the HnsnUPnP 120 into a format suitable for the terminal.                     

At this time, each terminal is connected to the WEB server of the HNSN 100, the request of each terminal is analyzed by the user application server 110 using XML and forwarded to the HnsnUPnP (120). In addition, the response from the HnsnUPnP 120 is converted to each terminal using XML and then transmitted to each user application server 110.

The HnsnRgIF 140 is a process that is in charge of RG registration, authentication, and access management, and communicates with RG 200 using SOAP over TCP / IP. In addition, it is a process performed by a daemon, and receives and processes a request from the RG 200.

Here, SOAP is a protocol used to make XML with Simple Object Access Protocol. It is a protocol that connects different things so that any platform can access the server and service using XML and HTTP.

The HnsnUPnP 120 is a process of receiving and processing equipment control and event control commands from the user application server 110. It is a process performed as a daemon and receives a request from the user application server 110 or receives a request from the RG 200 and processes it.

In addition, the device and the service description (description) file is obtained from the RG 200 and stored, and the user application server 110 uses it when controlling equipment.

At this time, each process performs an XML data parsing operation of request and response messages, and performs a task of referring to or changing a user and device related database 130.

Next, referring to FIG. 2, the protocol used between each process and RG in the HNSN is as follows.

The following protocol is used between the application server 110 and HnsnUPnP 120, which is a home network middleware.

1) use HTTP over TCP / IP to view the device list; 2) use SOAP over TCP / IP for device control; 3) Use GENA over TCP / IP for device event control.

In addition, the following protocol is used between the HnsnUPnP 120 and the RG 200.

1) use SSDP / GENA over UDP / IP for device discovery; 2) use HTTP over TCP / IP to maintain device description files; 3) using SOAP over TCP / IP for device control and status monitoring; 4) Use GENA over TCP / IP to control device events.

In addition, the following protocol is used between the home network interface HnsnRgIF 140 and RG 200.

1) use Register SOAP over TCP / IP for RG registration; 2) Use TCP / IP specification Alive / Bye SOAP for RG connection management.

As described above, the HNSN system according to the present invention provides a function of remotely updating an indoor gateway (RG) 200 or remotely updating each device 210 linked to the RG 200. .

When the user selects the Update command of the RG 200 on the web screen, the software update of the RG 200 is performed according to the message flow shown in FIG. 3. This will be described in detail as follows.

First, discovery and description perform a process defined in the UPnP protocol.

That is, the RG 200 is recognized as a UPnP device in the discovery process of the HNSN 100, and the device description file and the software update of the RG 200 are updated in the description process of the HNSN 100. Receive a service description (service description) for (S11 ~ S12).

In that state, when the user selects the software (S / W) update command of the RG 200 in the application, a SOAP request message is sent to the HNSN 100.

The HNSN 100 forwards the received SOAP request message (ACTION-Req: UPDATE) to the RG 200 (S13), and sends the SOAP response message (ACTION-Res) from the RG 200 to the user application. Transfer (S14 ~ S15).

At this time, in the case of a firmware update, the RG 200 is updated, and in the case of a device update, the corresponding device is updated (S16 to S17).

Thereafter, after executing a successful update, the RG 200 and the Device 210 are updated and rebooted (S18 to S19), respectively, and the Simple Service Discovery Protocol (SSDP) message (Alive) to the HNSN 100. Is transmitted (S20).

As described above, the protocol stack for remote software upgrade according to the present invention uses SOAP (HTTP) based on TCP / IP.

As described above, according to the present invention, it is possible to remotely control the software update for the home gateway (RG) or the device associated with the HNSN system.

Thus, it is possible to execute dynamic control and commands for the software of the gateway connected to the home network or the devices linked thereto by remote control of the user from any remote location.
