Method for file update in home network system

The present invention relates to a home network system, and more particularly, to a method for updating data of a portable device entering a home network.

The home network is the next generation IT technology that is attracting the most attention and is a collection of technologies for maximizing the convenience of life by combining with the Internet based on the control, management, integration and interworking of the home appliances. The home network is divided into lower network technology for physical data transmission, middleware technology for interworking with upper applications, and information home appliance technology applied to each home appliance according to its technical layer. It is now expanding into ubiquitous computing, combined with broadband communications, wireless Internet, and sensor technologies.

Universal Plug and Play (UPnP), Jini, Open Service Gateway Initiative (OSGi), and Home Audio / Video Interoperability (HAVi), which are currently the interface between the underlying network layer and the application layer for control and management of information appliances. The various home network middlewares coexist without any technical advantage. These various home network middlewares control, manage, and integrate information appliances in the home in their own way, and there is no method for exchanging each information.

In these home networking technologies, the technology for automatically storing and managing rapidly increasing personal data is not yet provided.

In particular, digital photographs using digital cameras and camera phones are frequently made by users, and the digital photographs thus generated are stored in individual portable equipment (eg, digital cameras and camera phones, etc.).

However, as these portable devices can be easily taken and individual portable devices have become smaller, their portability increases the frequency of taking pictures. It is true.

Also, in order to download photos, you must have a flash memory reader or cable, and since the file names are repeatedly attached to the pictures on the camera, you may make a mistake that may overwrite an existing image. This is a hassle to create a new folder.

On the other hand, data files such as cash registers, memo pads, diaries, etc. of individual users are often created through portable devices (eg, mobile communication terminals, PDAs, etc.). In order to take a lot of trouble.

In addition, portable devices have a limited storage capacity of the data, but the reality is that the amount of data to be stored is increasing.How to automatically update the data from the portable device to the home PC using home networking Research on the situation is required.

The present invention has been proposed to meet the above demands, and provides a method of updating a file in a home network system in which a file is updated accordingly when a portable device enters a home network using log data. Its purpose is to.

In addition, the present invention, because the data of the portable device is automatically transmitted to the server of the home network, the object is to solve the inconvenience of file transfer.

In addition, an object of the present invention is to facilitate the operation of the limited storage space of the portable device because the data of the portable device is automatically transmitted to the server of the home network.

According to an aspect of the present invention, there is provided a method of updating a file in a home network system, wherein the home network server discovers a predetermined device entering the home network and includes the predetermined device as a node of the home network. Making a first step; A second step of determining whether a predetermined device included as a node of the home network in the first step includes data to be updated to the home network server and notifying the home network server of this; And a third step of the home network server checking the download setting of the predetermined device and downloading the data to be updated according to the set download mode.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the same components in the drawings are represented by the same reference numerals and symbols as much as possible even though they are shown in different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In the present invention, the home network system is illustrated to be limited to a home network system using UPnP middleware. However, the present invention is not limited thereto. That is, the algorithm according to the present invention can be used in all home network systems using various home network middleware such as Jini, Open Service Gateway Initiative (OSGi), and Home Audio / Video Interoperability (HAVi).

1 is a configuration diagram of an embodiment of a home network system to which the present invention is applied.

As shown in FIG. 1, a home network system to which the present invention is applied includes a home network 11 supporting networking between respective devices in a home environment, home appliances 12 which are client devices of a home network system, and an information device ( 13), a home communication server 14 and a home network server 15 that operates as a server of the home network 11 and is connected to a subscriber network including a wired and wireless network.

Each home network system configured as described above supports home network middleware, so that a home application for a home service can communicate without considering details of devices supporting the home network middleware. In the standpoint of individual devices, only home network middleware can be connected to all service applications supporting the home network middleware.

2 is a block diagram of a communication layer of a home network system to which the present invention is applied.

As shown in FIG. 2, a communication layer of a home network system to which the present invention is applied is largely divided into a home application layer 21, a middleware layer 22, and a device layer 23.

Here, the home application layer 21 is a layer that supports application programs for home service. And, the middleware layer 22 is a layer that supports middleware for various home networks such as Jini, Open Service Gateway Initiative (OSGi), Home Audio / Video Interoperability (HAVi), and illustrates that UPnP middleware in an embodiment of the present invention. have. The device layer 23 is a layer for physical connection including a PHY layer 231 and a second layer 232, which are lower layers of an OSI (Open Systems Interconnection) 7 layer.

Each of the devices connected to the home network system to which the present invention is applied consists of such a home application layer 21, a middleware layer 22, and a device layer 23.

3 is a signal flow diagram of an embodiment of a networking process of a home network system to which the present invention is applied.

According to an embodiment of the present invention, a signal flow diagram of a networking process of a home network system to which the present invention is applied is shown in FIG. 3, when the portable device 31 enters a home network and the home network server 32 detects it. It's about making the client work.

When the home network server 32 finds the portable device 31 on the network (301), it assigns an address (302). Then, the device is recognized (Discovery) 303, the specification of the device (Description) 304, and the operation of the Event (Event) / Control (Presentation) (305).

Looking at each process, since the middleware UPnP according to an embodiment of the present invention is an IP (Internet Protocol) based network, IP is required for each device connected to the network. Accordingly, IP allocation, that is, address allocation ( 302 is first performed.

If each device is assigned an IP address through the address assignment 302, it is then necessary to recognize the devices to be controlled. To this end, the controller recognizes the device using a protocol called Simple Service Discovery Protocol (SSDP) (303). At this time, the controller searches for the devices of interest and the controller responds. In addition, when the controller is connected to the network, the controller automatically notifies other devices of the fact that the controller is connected, and periodically informs whether the connection is continued.

When the device is recognized (303), it is necessary to know what services are to be performed for each device. To do this, when the controller finds a controller, the controller sends a Uniform Resource Locator (URL) containing the specification of the device, and the controller gets the equipment specification in XML (eXtensible Markup Language) document from the controller. This document contains manufacturer information, product information (model, serial number,…), and a list of services.

The controller then takes the device specification from the controlled device, analyzes the service of the described device, and then sends an appropriate command to the controlled device to control it. The protocol used here is XML (eXtensible Markup Language) / SOAP (Simple Object Access Protocol). This is called control.

In the home network, the state of the device is often changed according to the surrounding environment. Sometimes these changes can be important to the user, so UPnP defines events. The controller pays attention to the state of the controller, and the controller delivers an event message to the controller when its state changes. Events are a pair of (name, value), and the protocol used in the event is GENA (Generic Event Notification Architecture) in XML format. This is called an event.

The controller may read an HTML page of the control text. This HTML page shows the user interface related to the use of the device, which also controls the device or shows its status. This is called a presentation.

4 is a signal flow diagram of an embodiment of an automatic update process upon recognition of a portable device by a home network server according to the present invention.

When the home network server 32 finds the portable device 31 entering the home network (301), the process of address assignment 302, device recognition 303, and device specification verification 304 as shown in FIG. Do this. At this time, the home network server according to the present invention transmits log data to the portable device 31 (401). In this case, the log data refers to time data when the last networking between the portable device 31 and the home network server 32 is performed.

Accordingly, the portable device 31 checks whether there is data after the date / time included in the log data (402). At this time, it is possible to confirm this through the entire data, but in general, it is assumed that only the data format previously set for the update function is checked.

On the other hand, the portable device 31 may be set to store such log data. In this case, the process 402 may be directly performed through the log data stored in the portable device 31 without having to receive log data from the home network server 32.

And, if there is data after the date / time included in the log data, it notifies that there is a file to be downloaded (Eventing) (403), and the home network server 32 is a mode for downloading to the portable device (31). Check (404). In this case, there are two modes for downloading, a manual mode for determining whether to download manually and an automatic mode for automatically downloading all the identified files.

Then, in accordance with the confirmed download mode, it downloads (405).

Thus, according to the present invention, the new data of the user's portable device 31 is updated to the home network server 32, the user can easily transmit the data of the portable device 31, and as the data is transmitted, The performance of the portable device 31 can be improved.

5a to 5d are detailed flowcharts of an embodiment of an automatic update process upon recognition of a camera device by a home network server according to the present invention.

5A to 5D will be described in detail using a home network system using UPnP as a middleware, specifically, a method of automatically downloading a photo of a portable device (camera phone or digital camera).

FIG. 5A illustrates a process in which a portable device (camera phone or digital camera) is added to a home network. Through the middleware, the home network recognizes that a new device has appeared in the network (301). In addition, an IP address is assigned in the address assignment process 302, and the portable device 31 assigned the address transmits an advertisement message for recognizing its existence to another device or the home network server 32. In operation 501, an authentication process is performed for the portable device 31 found in the device discovery step, and a user ID request is made through a control-query variable in operation 502.

The portable device 31 then responds (ID response) to the control request variable (Control-Query variable) (503).

In addition, if the portable device 31 checks whether the portable device 31 has access authority in the corresponding home network through the ID matching through the responded ID (504), and if the ID of the portable device 31 does not match, An abnormal process is performed (505).

When the IDs match and are authenticated, the home network server 32 requests a description of the device (506), and the portable device 31 has its own detailed information and service made of XML (eXtensible Markup Language). After providing the information (Description file) (507), the switch to the home mode (51) enables communication and control with other devices through the UPnP in the home network. In addition, the home network server 32 also recognizes the corresponding service of the device (52). Here, the home mode means that the corresponding device operates as one node of the home network.

FIG. 5B is a flowchart illustrating a method of automatically downloading a picture from the portable device 31. When the portable device 31 has a photo file to be downloaded (509), in the state 508 of switching to the home mode, FIG. The portable device 31 first sends an event message of the eventing step to the home network server 32 to notify the existence of the file to download (510).

In this case, log data of the home network server 32 may be transmitted through the process of FIG. 5A, or log data may be stored in the portable device 31 to confirm that there is a picture file to be downloaded to the portable device 31. It costs. If there is a photo file after the time of log data, it is recognized as a photo file to be downloaded.

Then, the user of the portable device 31 can select whether or not to set the automatic down mode on the portable device 31, if the automatic down mode, it can be downloaded without the user's operation. Therefore, when the home network server 32 sends a message for checking whether the portable device 31 is set to the auto-down mode through a control-query variable (511), the portable device 31 The UE transmits a response to the down mode setting through a control-query variable according to its state (512).

In response to the down mode setting from the portable device 31 being determined, if the auto down mode is set, the home network server 32 operates in the auto down mode (522).

In this case, the message indicating that the automatic down mode is transmitted includes the setting value of the automatic down mode previously set by the user of the portable device 31.

Here, the setting value of the auto-down mode preset by the user of the portable device 31 is set by the user of the portable device 31 and is a folder for setting data to be stored in the home network server. A setting field and a file remaining status setting field for setting whether to delete data to be downloaded from the portable device 31 at the time of downloading from the portable device 31.

In the preferred embodiment of the present invention, if the portable device 31 is set to the automatic down mode, the folder creation field is limited to creating a new folder accordingly. Because the automatic down mode requires that the setting from the portable device 31 be generated as little as possible by the presentation message. When the existing folder is used, a process of selecting and receiving the folder list is required. Because. Then, the file remaining status setting field for setting whether to leave the data to be downloaded to the home network server 32 in the portable device 31 at the time of downloading, copies the data to a value set by the user of the portable device 31. Set whether to copy or move. The home network server 32 automatically downloads the photo file without the presentation message to the portable device 31 by using the setting value of the automatic down mode preset by the user of the portable device 31 as described above. Will be made.

On the other hand, if the response 512 to the signal of 511 is not in the automatic down mode, the home network server 32 asks whether to download the picture to the portable device 31 (513). In this case, since a user's selection is required, a presentation message is transmitted along with a control-query variable so that the user can browse the portable device 31 for the user's selection.

If the response is not to download, the process is terminated. If it is to be downloaded, the process proceeds to the next step (514).

In addition, if it is confirmed that the download is performed through the process of 514, the home network server 32 sends a message for confirming whether to create a new folder for downloading the corresponding file through a control-query variable. Pass (515). At this time, since the control-query variable used is determined by whether the portable device 31 is selected, a request for adding a function of browsing an interface for user selection through a presentation message is requested. (515).

Then, the interface by the presentation message is browsed through the screen of the portable device 31, and the user of the portable device 31 can easily view and select the result, and control the result of the control-query variable. (516).

The home network server 32 then creates a new folder if the user's choice is to create a new folder (517). At this time, the new folder is created in the home network server 32 in the photo directory in the home network server 32 in which a folder named by a user in a predetermined format such as a date is created.

On the other hand, when not creating a new folder will be described with reference to Figure 5c to be described later.

In operation 518, the portable device 31 inquires whether the file to be downloaded is to be moved or copied. This relates to whether or not the memory of the portable device 31 is reset. In this case, a presentation message is transmitted along with a control-query variable so that browsing for the user's selection is performed on the portable device 31.

In operation 519, the user's selection for the operation 518 is received. That is, the control request variable (Control-Query variable) according to the user's selection is passed to the home network server (32).

When the home network server 32 requests the download of the photo file as a control action message (520), the portable device 31 uses a transmission method adopted by the portable device 31 rather than UPnP. The photo file is transmitted through out of band transfer through a wireless LAN (WLAN), ultra-wideband communication (UWB), Bluetooth, and the like (521).

5C is a flowchart illustrating an embodiment of a case of downloading using an existing folder.

As shown in Fig. 5C, when the response to the signal of 515 does not create a new folder, the home network server 32 transmits the existing folder list to the portable device 32 so that the user can enter the existing folder. One can be specified (523). In this case, since a user's selection is required, a presentation message is transmitted along with a control-query variable so that the user can browse the portable device 31 for the user's selection.

When the folder is selected (524), the transfer of the photo file is performed through the process of 518 to 521, and the file name is changed and stored so as to be stored (525). In other words, the user downloads the picture to a folder designated by the user. Since the file name of the portable device may be repeated periodically, the original stored picture file may be overwritten, and the file name is changed by adding the date and time.

5D is a flowchart illustrating an embodiment of a process of immediately outputting a downloaded picture.

5A through 5C, when the download of the picture is completed, the user of the portable device 31 may select one of the display devices connected to the home network and view the downloaded picture file through the display device.

That is, the user of the portable device 31, upon completion of the download, requests the home network server 32 to immediately output the screen (526).

In response to the request of 526, the home network server 32 transmits a list of display devices to be output (527), and when the user designates an output display device through the list for the transmitted display devices (528). The picture data may be transmitted through a home network that is already formed, and may be directly displayed through a screen of the selected output display device (529).

Meanwhile, according to the setting, the home network server 32 transmits a message to the portable device 31 that prompts the user to immediately output the downloaded picture along with a message indicating that the download is completed. In response, the process of 527 to 529 may be performed.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, because the data of the portable device is automatically transmitted to the server of the home network, there is an effect of eliminating the inconvenience of file transfer by not using unnecessary connectors and the like.

In addition, since the data of the portable device is automatically transmitted to the server of the home network, the present invention has an effect of easily managing the limited storage space of the portable device.
