The present invention relates to a home network system using a service bundle based on the home networking standard OSGi, which is a home gateway middleware. More specifically, the present invention relates to an existing service bundle. When creating a new OSGi service, the present invention relates to a home network system and a home networking method for creating a new service by dynamically linking an existing service bundle without having to create a new Java program bundle for the service.

In general, in the home networking field, various domestic and international standard activities are progressing due to various application environments, and OSGi is also developing as a major standard in the home networking field.

In terms of the domestic and international technology, the specification is led by the OSGi Alliance, and other companies and individuals are introducing technologies that apply it. The OSGi specification mainly defines service bundles programmed in Java that run on OSGi middleware and middleware, and how to distribute service bundles from remote servers to gateways with OSGi middleware installed. Focus on how to.

As a related art related to such home networking technology, there is, for example, Korean Patent Publication No. 10-2005-0066066. The prior art comprises a device on a plurality of home networks loaded with various middleware, a home gateway equipped with a plurality of middleware bundles for supporting the OSGi platform and various middleware, and a service provider for providing interoperability services between middleware. Therefore, OSGi bundle, which integrates and converts functions of different middleware on the user's home network, can be downloaded to the home gateway and operated on the OSGi platform, thereby providing services suitable for individual characteristics of the service user.

In addition, Korean Patent Laid-Open No. 10-2005-0073015 includes a service role setting unit for determining a service role for sharing a predetermined standard service through an election algorithm, and a service role setting unit for sharing a service on a network. It is disclosed that the service request processing unit is configured to include a service request processing unit for requesting processing of a standard service required for supporting a predetermined service to an OSGi service platform of an externally designated device according to the determined service role.

However, the prior arts have many advantages in that they use a standardized standard when applying the OSGi platform to home networks and telematics. However, each new service bundle is required in FIG. As shown, there is a drawback to creating bundles with complex Java programming each time.

If you go through a Java program, you need programming, compilation, installation on the OSGi platform of the gateway, and error checking in advance. This process is very difficult to do without an expert.

As a result, new service development is inconvenient, and when Java developers who are fluent in the OSGi standard are not supported, service development and modification are impossible. Other conventional techniques of the above-mentioned conventional documents also use a method of implementing through Java programming to implement the OSGi service bundle, there is no improvement method for this.

In order to solve the problems of the above-described prior arts, the new service is configured only with dynamic linkage information of existing bundles already installed as basic component bundles without going through a complicated Java program for OSGi, while maintaining compatibility within OSGi specifications. An object of the present invention is to provide a home network system in which services can operate and a method of operating the system.

The present invention provides a home network device including a plurality of OSGi middleware, a home gateway equipped with an OSGi platform and a plurality of OSGi middleware bundles, and an external network connected to the home gateway. In the network system, the home gateway, Dynamic linkage service storage unit for storing a plurality of dynamic linkage service; And a master bundle for OSGi that reads the information of the dynamic linkage service from the dynamic linkage service storage and executes the dynamic linkage service.

In addition, the dynamic linkage service is managed only by a master bundle independently of OSGi middleware, and is composed of a plurality of component bundles 5b, and the dynamic linkage information for configuring the dynamic linkage service is a component bundle. It is characterized by consisting of name, sequence number, execution method, execution condition.

The master bundle for OSGi may further include: an execution command detecting unit detecting a dynamic interlocking service execution command from a user, a loading unit reading information of a dynamic interlocking service from the dynamic interlocking service storage unit, and the loaded dynamic An OSGi standard conversion unit for converting an interlocking service according to the OSGi standard, and a dynamic interlocking service control unit for controlling the dynamic interlocking services converted to the OSGi standard.

In addition, a home network device equipped with a plurality of OSGi middleware, a dynamic interlocking service storage unit for mounting the OSGi platform and a plurality of OSGi middleware bundle, and stores a plurality of dynamic interlocking services; Operation of a home network system comprising a home gateway having a master bundle for OSGi for reading the information of the dynamic link service from the dynamic link service storage unit and executing the dynamic link service, and an external network connected to the home gateway. A method comprising: detecting a service execution request from a user from an execution command detecting unit of the master bundle, determining whether there are lower component bundles to be executed by analyzing the detected service information, and performing lower component bundles to be executed Loading the information on the dynamic linkage service from the dynamic linkage service storage unit, converting the dynamic linkage service to the OSGi standard from the loaded information, and executing the dynamic linkage service converted to the OSGi standard. Characterized in that consists of do.

Hereinafter, a home network system and a method of operating the same according to the present invention will be described in detail with reference to the accompanying drawings.

The home network system according to the present invention comprises a home network device (not shown), a home gateway, and an external network (not shown). The home network apparatus is equipped with a plurality of OSGi middleware, and the external network is connected to the home gateway 1 as in the prior art.

1 to 5, the home gateway 1 according to the present invention includes a hardware, an operating system, a Java virtual machine, an OSGi middleware 7, a plurality of existing OSGi middleware bundles 2, It consists of the master bundle 3 for OSGi, and the dynamic interlocking service storage part 4. As shown in FIG.

The OSGi framework of the home gateway 1 according to the present invention includes hardware, an operating system, a Java virtual machine, OSGi middleware, and a plurality of OSGi middleware bundles as shown in FIG. This is the same as the OSGi framework, so a detailed description thereof will be omitted. The home gateway according to the present invention further comprises a master bundle 3 for OSGi and a dynamic interlocking service storage unit 4 in addition to the above-described prior art configuration.

The dynamic linkage service storage unit 4 stores a plurality of dynamic linkage services 5. As shown in FIG. 2, the plurality of dynamic interlocking services 5 are managed only by the master bundle 3 independently of the OSGi middleware 7.

Each dynamic interlocking service 5a is composed of a plurality of basic component bundles 6 constituting sub-components, as shown in FIG. 4, and the plurality of basic component bundles 6 constitute one dynamic interlocking service. As shown in FIG. 5, for example, the dynamic linking information may include a component bundle name, an execution sequence indicating an execution sequence of the corresponding component bundle, an execution method indicating an input variable value of the corresponding component bundle, an execution time of the corresponding component bundle, or the like. It consists of execution conditions that indicate device status or the status of other dynamic interlocking services.

In addition, the home gateway 1 according to the present invention includes a master bundle 3 for OSGi. 1 and 2, the master bundle 3 manages the information of the dynamic interlocking service 5, and executes the dynamic interlocking services according to OSGi standards for starting, terminating and registering services. .

As shown in FIG. 9, the master bundle 3 for OSGi includes an information loading unit 3a, an OSGi standard conversion unit 3b, a dynamic interlocking service control unit 3c, and an execution command detecting unit 3d. It consists of. When the execution command detecting unit 3d detects a dynamic interlocking service execution command from the user, the detected service information is interpreted to determine whether there are lower component bundles to execute, and if the lower component bundles to execute exist, the information loading unit. (3a) loads the information of the dynamic linkage service from the dynamic linkage service storage unit 4, and the OSGi standard converting unit 3b converts the dynamic linkage service from the loaded information according to the OSGi standard. In addition, the dynamic linkage service control unit 3c executes the dynamic linkage service converted to the OSGi standard.

That is, if a predetermined event (fire, external intrusion) or a command is delivered to the user to operate a specific dynamic linkage service through a command button or a web screen of the remote controller, the execution command detecting unit 3d detects this and loads the information. After reading the corresponding dynamic interlocking service from the dynamic interlocking service storage unit 4 through the unit 3a and reconverting the information according to the OSGi standard operable in the OSGi middleware through the OSGi standard converting unit 3b, The basic bundles designated as the respective basic components are controlled through the dynamic linkage service control unit 3c.

As described above, the home network system according to the present invention provides a method of executing a new service through a master bundle in order to dynamically operate an existing component service bundle to form an information and to operate it as an OSGi standard service.

In the prior art, when a new service is added, such a new service is always programmed with a new Java program for OSGi that conforms to the OSGi standard, a Java program compilation process, and stored in the OSGi home gateway. And while the process to install as a bundle in the OSGi middleware, but as shown in Figure 6, in the present invention, a new service can be created without the Java programming.

For example, in the prior art, when Java programming is performed, as shown in FIG. 12, a professional programming process is required. However, in the present invention, as shown in FIG. 7, the new service is configured in the form of interworking information. Rather, it can be created by simply linking information dynamically.

That is, for example, when the new service is set to 'outing mode', the new service sets 'light off' and 'TV off' as component bundles to be interlocked, and designates the sequence number as '1' as interworking information. Since the new service can be configured in the form of interworking information by inputting the number of extinctions as the execution method and the execution time as the execution condition, the information is dynamically linked without the need for Java programming of the component bundles. Can be made through the process.

The dynamic linkage service information generated through this process includes the dynamic linkage information related to each subcomponent in the dynamic linkage service as shown in FIG. 8 by the master bundle 3 for OSGi complying with the service start, end, and registration process according to the OSGi standard. Will be executed according to

For example, when a new service is called outing mode, when a user goes out in a home where a home gateway is installed, a bundle that turns off a light through the home gateway, a bundle to stop the air conditioner, a bundle to close the curtain, and a bundle to turn off the audio device It is necessary to operate all at once. Through the present invention, the bundle is linked to and stored in one dynamic linkage service as a component of the dynamic linkage service without relying on Java programs for OSGi. Press the button on the remote control or web screen to operate.

As another example, when a new service is called a fire response mode, a control bundle that walks the curtain in the event of a fire, a control bundle that sounds an alarm, a control bundle that locks all gas valves, and a control to open the front door should be made at once. . In the conventional OSGi middleware environment, a new bundle that integrates all of these bundles must be made into a Java program of the OSGi standard. However, the present invention does not depend on the Java program, but simply designates the interlocking bundles in the dynamic interlocking service. Through this, it is possible to create and execute a dynamic interlocking service for overall fire response.

As another example, when a new service is called a sleep mode, the main lamp turns on a bundle that turns off the lights, the sleeper turns on a bundle that turns on the lights, and the air conditioner turns off the bundles and audio devices that control the sleep mode. Control bundles should be operated at once, and in such a case, a new dynamic linkage service called sleep mode can be defined by binding basic bundles such as light control bundle and air conditioner control bundle as interworking information without writing new OSGi standard Java program. When the user goes to bed, only one command of the sleep mode is transmitted to the remote controller to control all the basic bundles to execute the sleep environment.

As described above, according to the present invention, since the new service can be configured in the form of interworking information, it can be made through a process of dynamically interworking information without the need for Java programming of the component bundles.

The embodiments and drawings attached to this specification are merely to clearly show some of the technical ideas included in the present invention, and those skilled in the art can easily infer within the scope of the technical ideas included in the specification and drawings of the present invention. It is apparent that all modifications and specific embodiments that can be included in the scope of the technical idea of the present invention.

In the past, technologies related to the OSGi platform have been composed of service bundles as Java programs conforming to the OSGi standard according to the specifications of the OSGi Association. Therefore, OSGi and OSGi are required when new services are needed after the home server is installed in each home. We had to find a Java expert who was familiar with the existing home server and OSGi middleware. In addition, the process of compiling and distributing them has to go through a professional process, and due to the nature of the program, it has to be installed in each home again and error checking is performed.

According to the present invention, the newly developed service has a master bundle for OSGi so that the newly developed service operates within the OSGi standard, and the new service is configured by dynamically associating a bundle of each component type already supplied in the home gateway. By running it as an OSGi master bundle, you can:

1. When developing new services, complicated processes can be omitted when programming, compiling, distributing, and installing Java.

Conventionally, in order to make an OSGi service, Java bundles of the OSGi standard had to be made through Java programming. However, through the present invention, the OSGi service standard is maintained by the master bundle, but the new service is simply made up of dynamic linkage information of existing services. The specialized process of programming and compiling Java is omitted.

2. When installed as a new service, error verification can be simplified.

Particularly, in the case of a new service developed as a Java program in the related art, since there are Java codes newly added or created in the program, it becomes a completely new program different from the existing one, so after installation on the home gateway, an error verification operation must be strictly performed. The new service developed through the program is in the form of interworking information, not a program, and since the existing bundle of each component has already been verified, error verification is simplified. That is, after only the master bundle that executes the dynamic interlocking service is initially verified, new dynamic interlocking services created afterwards do not need to be verified.

3. You can create new services universally independently of OSGi middleware and Java Virtual Machine (JVM).

OSGi middleware and Java virtual machine (JVM) that runs Java also have many types, so if you make a bundle by programming in Java as in the past, the code in the program may have some dependent parts according to each product type. If the new bundle is developed in the form of information executed by the master bundle, it can be independently developed and distributed to various types of OSGi middleware and JVM.
