Description

Ubiquitous failure handling system and method {SYSTEM AND METHOD FOR PROCESSING FAILURE OF UBIQUITOUS}

The present invention relates to a ubiquitous failure handling system, and more particularly, to a system and method for monitoring a home network system to diagnose and recover a failure.

The present invention is derived from a study conducted as part of the IT new growth engine core technology development project of the Ministry of Information and Communication and the Ministry of Information and Communication Research and Development. [Task Management Number: 2006-S-066-02, Title: High Reliability Ubiquitous Home Adaptive Middleware development technology].

In general, ubiquitous means a human-centered computing environment that embeds computer chips into everything and optimizes the invisible living environment through mutual communication. In order to realize ubiquitous, the advancement of information technology, nanotechnology, and biotechnology that can be applied to all everyday things such as home appliances, furniture, and automobiles is required.

The use of such ubiquitous computing technology in the home is called a ubiquitous home network system, and the operation of the conventional home network system will be described with reference to the accompanying drawings.

1 is an exemplary view showing a conventional ubiquitous home network system.

A typical home network system 100 is constructed through a home gateway (RG) 102 and a local network 104. The local network 104 is implemented via telephone lines, power lines, wireless LANs, and the like. The heterogeneous home network first to third devices 106, 108, and 110 are connected to the local network 104 to share information, or a television receiver, a digital set-top box, an audio speaker, and the like are connected to the AV information. It provides a function to control by replacing or connecting a refrigerator, washing machine, boiler, and the like. The RG 102 is connected to a Home Network Serving Node (HNSN) 114 via the Internet network 112. The HNSN 114 is a device for managing the RG 102 to allow the RG 102 to be connected to the Internet or to receive various additional services. A user application server (UAS; hereinafter referred to as 'UAS') provides a service to the first to third devices 106, 108, and 110 through the Internet network 112. The HNSN 114 remotely controls the first to third devices 106, 108, and 110 managed by the home RG 102. To this end, the HNSN 114 recognizes the first to third devices 106, 108, and 110 through the RG 102 in the discovery process, and the first to third devices 106 in the description process. Receive the device description file and the service description file;

On the other hand, when a user selects a device control command in the UAS 116, a Simple Object Access Protocol (SOAP) request message of the command is transmitted to the HNSN 114. The HNSN 114 then forwards the received SOAP request message to the RG 102, which forwards it to the device and forwards the SOAP response message received from the device to the user application server 116.

Such a conventional home network system can support fault diagnosis and recovery of home network devices through remote control and monitoring of home network devices based on UPnP (universal plug and play) protocol through user application server, HNSN, and RG configuration. Can be. However, this is only possible if the device type or manufacturer is single or limited.

That is, the aforementioned ubiquitous home network has a problem in that it is impossible to control and monitor all devices operating in an environment in which heterogeneous media or heterogeneous protocols are mixed. In addition, if device failure information provided by RG is provided to HNSNs and UASs without device standardization, HNSNs and UASs may not be able to decrypt them, making it impossible to diagnose and recover from device failures.

2 is a block diagram showing the configuration of a ubiquitous failure processing system according to the present invention.

The ubiquitous failure handling system is a mixed failure that can occur in the ubiquitous home, such as misuse, misconfiguration, or resource leakage, as well as device or service failures, to prevent user complaints due to uncomfortable and unreliable environment caused by errors. (Blended-Fault) can also be used to remotely autonomously diagnose and recover the device (201, 202), the RG (210), the operator server (BS; Business Server, hereinafter referred to as 'BS') 220 and AS center server 230 is configured.

The device 201 receives a control signal according to a communication method determined by the ubiquitous home network and performs a corresponding function.

RG 210 collects device and topology / network fault information on ubiquitous home networks, manages download and execution of fault diagnosis services, stores and retrieves fault message logs, handles standard fault messages and standard recovery messages, and develops faults developed by device manufacturers. Tunnel a message to support communication between the diagnostic service and the physical device. In addition, the RG 210 is a device manager 211 tunneling a message, a resource manager (RM) collecting topology and network error information (hereinafter referred to as 'RM') 212 , A service manager (SM) for executing and managing legacy device diagnostic programs (hereinafter referred to as 'SM') 213, and a repository manager (RPM) for collecting failure message log information. It is configured to include a 'RPM' 214, and a failure manager (AFM; hereinafter referred to as 'AFM') 215 for transmitting a message according to the occurrence of the device failure event. Here, the legacy device diagnostic program refers to a program for diagnosing a failure of a passive device having a concept opposite to an intelligent device.

The BS 220 identifies the RG 210 and the AS center server 230, and manages connection management with the RG 210, fault message branches, and transactions.

The AS center server 230 diagnoses and recovers a failure based on a connection management with the BS 220 and a failure message for the received product.

The operation according to the failure diagnosis and recovery of the ubiquitous failure processing system will be described in detail as follows.

3 is an exemplary diagram for describing a device error occurrence message format according to an embodiment of the present invention, Figure 4 is an illustration for explaining the operation of the ubiquitous failure processing system when a device failure according to an embodiment of the present invention It is also.

Referring to FIGS. 2 to 4, a failure occurs in a device 201 such as a home appliance, and a failure message is displayed in the device manager (DM) in the RG 210 (hereinafter, referred to as 'DM') 211. DM 211 transmits a fault code (Raw Fault Code) in the payload (Payload) in the fault message as shown in Fig. 3 (AFM: Autonomous Fault Manager. To send). As shown in FIG. 3, the AFM 215 receives a DM failure message received as a mechanism of operation when a failure event occurs in the device, as shown in FIG. 4. 209 is transferred to the BS 220.

Then, the BS 220 secures and maintains all the device lists supporting remote diagnosis and recovery from the manufacturer AS center server 230 of each device through an initialization operation mechanism with the AS center server 230 as shown in FIG. 5. .

Upon receiving the standardized fault message from the AFM 215, the BS 220 checks the device type, the device manufacturer, the model name, the serial number, and the like in the standard fault message, and the device and AS center server 230 obtained through FIG. On the basis of the mapping table () for the mapping table, the failure message is sent to the manufacturer AS center server 230 of the corresponding device.

In response, the AS center server 230 receiving the failure message from the BS 220 analyzes the failure message to diagnose the cause of the failure, and a standardized failure recovery message for failure recovery as shown in FIG. 210).

The RG 210 converts the received standard failover message into a local failure message that can be recognized by the device 201 and delivers it to the device 201 to recover from the failure.

Meanwhile, the resource manager (RM) 212 in the RG 210 collects error information of various heterogeneous network topologies on the ubiquitous home and transmits a failure message to the AFM 215 when a problem occurs. In other words, RM supports the diagnosis / recovery of mixed failures that can occur in ubiquitous home, such as misuse, misconfiguration, and resource leakage, which are different from fault diagnosis for a specific device / service.

The operation mechanism related to this is the same as the operation mechanism when the device failure described above will not be described in detail.

The Service Manager (SM) 213 can diagnose failures for devices such as legacy devices (e.g. passive devices such as sensors, actuators, etc.) that cannot generate a Pre-Defined Fault. It is responsible for executing and managing the legacy device diagnostic program (216). The legacy device diagnostic program 216 refers to a program for diagnosing a failure state of the legacy device.

When the legacy device is connected, the SM 213 downloads and executes the legacy device diagnostic program 216 through the software download request mechanism shown in FIG. The executed legacy device diagnostic program 216 diagnoses a failure state of the legacy device through communication with the device 201 by using the message tunneling function provided by the DM 211, and sends a failure message to the AFM 215 when a problem occurs. It serves to convey.

RPM 214 stores a log of all failure messages occurring on the ubiquitous home, the failure message log information stored in the RG when the failure log request from the AS center server 230 or BS 220 as shown in FIG. Search and provide.

Meanwhile, the AFM 215 performs various additional functions related to diagnosis / recovery in addition to the above-described message conversion and transfer function. That is, the AFM 215 diagnoses the cause of the error through the information of other components of the adaptive middleware collected through the RPM 214 and delivers only the trouble in question to the AS center server 230 through the BS 220. Provide error filtering. In addition, after receiving a home network diagnosis from a user, a failure diagnosis service program collects context information from the adaptive middleware manager of DM, RM, and SM to determine whether there is a problem with the currently running service, a device in operation, or a network. Based on the error diagnosis, the error cause is diagnosed, and the error is detected and the error message is delivered to the operator / server.

The AFM 215 stores an error class repository that maps the fault types according to the various fault types required in the fault detection phase into a large range of fault classes and a small range of fault classes. Fault Class Repository), and when a fault occurs, the fault class repository is used to determine the formal fault class for the fault type. Based on the determined error class, additional information is gathered in real time, which is necessary to diagnose the cause of the error that can occur within the corresponding error class category and the smaller subclass of error.

First, the AFM 215 includes an information collection unit 215a, a failure diagnosis unit 215b, and a failure classification management unit 215c.

The information collecting unit 215a collects additional information according to the obstacle. The additional information may include information periodically collected and status information collected on demand. Information collected periodically by the information collecting unit 215a may include information such as physical device topology, logic device topology, service topology, home control, and command log. And failure, service status and failure, network status and failure, home control log, and the like.

The failure diagnosis unit 215b detects a failure in the home network, and diagnoses the cause of the failure by receiving additional failure information collected from the information collection unit 215a and a manufacturer-dependent failure message from the DM.

The failure classification management unit 215c manages the failure by classifying the error type according to the failure type of the diagnosed failure cause. The failure classification management unit 215c includes a network situation failure manager 11 that manages error information of a network topology, a configuration failure manager 13 that manages error information according to a device, a network, and a service, an intelligent device, and a legacy device. It is configured to include a device failure manager 15 for managing the error information according to.

As described above, the AFM 215 provides a method of repeatedly finding the root cause of the failure based on an error diagnosis rule. When the cause of the filtered error is diagnosed, the AFM 215 transfers the error cause message to the device manufacturer AS center server 230 via an external operator / only server through an error message-based failure handling framework.
