If the error can be checked and corrected, the measurement data or the sensing data corrected for the error is received from the M2M gateway 20 and stored. If the error cannot be corrected, the measured data or sensing data in which the error occurred is stored and the Data generation before the time of generation of the failed measurement data or detection data The error correction is performed among a plurality of manufacturer servers (that is, servers operated by a manufacturer who manufactures a plurality of M2M terminals) (not shown) connected to the M2M server 30 after rolling back the switch. The repair request message for the at least one or more M2M terminals may be transmitted to the manufacturer server corresponding to the at least one or more M2M terminals that are impossible.

To this end, the M2M server 30 stores a first database in which the measurement data or the sensing data, the measurement data and the sensing data in which the error is corrected, and the second data in which the measurement data or the sensing data in which the error occurs are stored separately. It may include a base.

In addition, the M2M server 30 is each operation information from the plurality of M2M terminals (10a, 10b, 10c) received from the M2M gateway 20, the received measurement data or sensed data, the measurement data corrected the error Alternatively, a virtual operating environment based on an application program interface (API) is generated for each of the plurality of M2M terminals 10a, 10b, and 10c by using the sensed data and the measurement data or the sensed data in which the error occurs, and the M2M server 30 The API-based virtual operating environment generated for each of a plurality of M2M terminals 10a, 10b, and 10c may be provided to the plurality of manufacturer servers connected to the M2M server 30 by a network, and the plurality of manufacturer servers may be By using the API-based virtual operating environment for the repair process of the M2M terminal that generated the measurement data or the sensing data in which the error occurs, or the manufacturing process of the M2M terminal later.

As a result, the stability of the M2M system can be improved. It becomes possible.

At this time, the M2M server 30 and the M2M gateway 20 may be connected to the network by a core network and an access network, where the access network is a network that can communicate with the core network xDSL, HFC, FTTH, PLC, Satellite network, GERAN, UTRAN, eUTRAN, Wireless LAN, or WiMAX (Wibro) may include, the core network is IP connection, access network control, network service control, interconnection with other networks, roaming function And the like, which may include 3GPP CN, ETSI TISPAN CN, 3GPP2 CN, IMS, and the like.

In addition, the M2M server 30 determines whether an error occurs in the collected data or the sensed data transmitted from the M2M gateway 20 or a plurality of M2M terminals 10a, 10b, and 10c received from the M2M gateway 20. A detailed process of generating a virtual operating environment for each of the plurality of M2M terminals 10a, 10b, and 10c by using each operation information will be described in detail with reference to FIGS. 2 to 6.

2 is a flowchart of a method of verifying data reliability based on M2M according to a preferred embodiment of the present invention, and FIG. 3 is a reference diagram of a method of verifying data reliability based on M2M according to a preferred embodiment of the present invention.

As shown in FIGS. 2 and 3, the M2M server 30 stores the measured data and the sensed data transmitted from the plurality of M2M terminals 10a, 10b, and 10c according to a predetermined period in S100. Collect through.

If the M2M server 30 determines whether an error occurs in the measurement data or the sensing data in S200, and if no error occurs in the measurement data or the sensing data, the M2M server 30 reads the measurement data or the sensing data in S300. When the measurement data or the sensing data has an error in the first database, the M2M server 30 transmits the measurement data or the sensing data in which the error occurs among the plurality of M2M terminals 10a, 10b, 10c in S400. Check whether error correction is possible in at least one or more M2M terminals.

In this case, in S200, the M2M server 30 compares the measurement data or the sensing data with a pattern of a plurality of previous time measurement data or the sensing data previously stored in the M2M server 30, and then the measurement data or It may be determined whether an error of the sensed data occurs.

For example, a plurality of M2M terminals for measuring the state of the sea wave was measured at 16 o'clock on February 20, 2013 while transmitting data within an error range compared to the data collected in the past until 15 o'clock on 20 February 2013. When the period and the wave data are suddenly changed, the M2M server 30 may include a pattern of a plurality of previous time data (that is, a plurality of wave periods and wave data collected at a previous time) previously stored in the first database. It is possible to determine whether an error occurs by comparing wave period and wave data measured at 16:00 on February 20, 2013.

In addition, the detailed process of S400 will be described in more detail with reference to FIGS. 4 and 5.

If it is determined in S400 that error correction in the at least one or more M2M terminals is impossible, in S500, the M2M server 30 stores the measurement data or the sensing data in which the error occurs in the second database, and in S400, If it is determined that error correction is possible in the at least one or more M2M terminals, the M2M server 30 transmits the measured or corrected data in which the error is transmitted from the at least one or more M2M terminals in S600 to the M2M gateway 20. After receiving through) and stores in the first database.

At this time, after S500, the M2M server 30 transfers the first database before the generation time of the measurement data and the detection data in which the error occurs (in other words, at a period before the generation cycle of the measurement data or the detection data in which the error occurs). At least one M2M to a manufacturer server corresponding to at least one M2M terminal generating the measurement data or the detection data that cannot be corrected error among the plurality of manufacturer servers connected to the M2M server 30 and the network connected to the M2M server 30. The method may further include transmitting a repair request message to the terminal.

In S700, after the M2M gateway 20 collects operation information of each of the plurality of M2M terminals 10a, 10b, and 10c from the plurality of M2M terminals 10a, 10b, and 10c, the collected plurality of M2M terminals 10a, 10b and 10c) transmit operation information to the M2M server 30.

In this case, the respective operation information in S700 may be information on a method of generating the measurement data or the sensing data in a plurality of M2M terminal (10a, 10b, 10c).

M2M server 30 at S800 the operation information of each of the plurality of collected M2M terminals (10a, 10b, 10c), the measurement data or sensing data stored in the M2M server 30 at S300, M2M server 30 at S500 The virtual operating environment for each of a plurality of M2M terminals 10a, 10b, and 10c by using the measurement data or the sensed data in which the error is stored, and the measurement data or the sensed data in which the error is corrected in the M2M server 30 in S600. When you create a shutdown is done.

At this time, the M2M server 30 at S800 is measured data or sensed data stored in the first database at S300, measurement data or sensed data having an error stored at the second database at S500, and the first data at S600. A plurality of M2M terminals are classified in such a manner that the error-corrected measurement data or sensing data stored in the base are classified according to the generation location and the generation time and then matched with the operation information of each of the collected plurality of M2M terminals 10a, 10b, and 10c. Since the virtual operating environment for each of the (10a, 10b, 10c) can be generated, it is possible to determine the cause of the error of the measurement data or the detection data in which the error occurs in the virtual operating environment (for example, a specific M2M terminal is The measurement data or the sensing data in the humidity error, or the measurement data due to network problems in the M2M terminal located in a specific area Alternatively, the sensing data may generate an error, or measurement data or sensing data generated by a specific M2M terminal at a specific time may be determined to be an error), and the M2M server 30 sets the virtual operating environment as the M2M server 30. After providing to a plurality of manufacturers server connected to the network and the plurality of manufacturers server it is possible to minimize the frequency of occurrence of data generation error in the M2M terminal to be manufactured later using the virtual operating environment.

As shown in FIGS. 4 and 5, the M2M server 30 transmits an error correction request message to the M2M gateway 20 in S410.

If the M2M gateway 20 checks whether the at least one M2M terminal can correct its own error according to the error correction request message in S420, and if self error correction is impossible, the M2M gateway 20 cannot correct the error in S430. Is transmitted to the M2M server 30, the M2M server 30 performs the S500 according to the error correction impossible message.

In addition, when the M2M gateway 20 checks whether the at least one M2M terminal may correct its own error in S420, when the self error correction is possible, the measurement data or the sensing data in which the error is corrected by the at least one M2M terminal in S440. Generates and transmits the M2M gateway 20 to the M2M gateway 20, and when the M2M gateway 20 transmits the error-corrected measurement data or the sensed data to the M2M server 30 in S450, S600 performs the M2M server 30. do.

At this time, the self error correction in the S450 is the measurement data or detection at the time before the determination of the error of the measurement data or the detection data in the at least one or more M2M terminal, as shown in Figure 6 M2M server 30 When there is an auxiliary operation unit that can replace the function of the main operation unit that generated the data, the auxiliary operation unit may generate measurement data or sensed data in which the error is corrected by operating the auxiliary operation unit. The change of the negative operation may be performed by a remote entity management (REM) process for the at least one or more M2M terminals of the M2M gateway 20.

In the M2M-based data reliability verification method of the present invention, the M2M server 30 determines whether an error occurs in the measurement data or the sensing data transmitted from the plurality of M2M terminals 10a, 10b, and 10c according to a predetermined period. If it does not occur, the measurement data or the sensing data is stored, and if an error occurs, the M2M gateway 20 checks whether the self error can be corrected. If the error cannot be corrected, the measurement data or the sensing data having an error are stored, and the database is rolled back before the generation time of the measurement data or the sensing data having the error.

The M2M server 30 receives the operation information of each of the plurality of M2M terminals 10a, 10b, and 10c through the M2M gateway 20, and then the respective operation information, the measurement data or the sensing data, and the error. A plurality of M2M servers 30 connected to the M2M server 30 by creating a virtual operating environment of each of the plurality of M2M terminals 10a, 10b, and 10c using the modified measurement data or the sensed data and the measurement data or the sensed data in which the error occurs. Each of the virtual operating environment is provided to the server of the manufacturer.

Accordingly, it is possible to improve the reliability of the M2M system since it is possible to determine whether an error occurs in the data transmitted from the plurality of M2M terminals on the M2M system and correct the error data in real time in the M2M server.

In addition, the M2M server generates a virtual operating environment for each M2M terminal by using the result values accumulated in the process of determining whether an error occurred in the data transmitted from a plurality of M2M terminals on the M2M system and correcting the data that has occurred. The result values accumulated in the manner provided to the terminal manufacturer side are reflected in the repair process of the M2M terminal that generated the error data or the development process of the M2M terminal later, thereby minimizing the time required for repair of the error-producing M2M terminal or manufacturing later. The occurrence of data generation error in the M2M terminal can be minimized, and as a result, the reliability of the M2M system can be improved.

For example, in the conventional case, the M2M corrected the error through a process such as the number of M2M terminals that generated the error data, the cause of the failure, the correction according to the cause, and the test using a simulation robot. Although the terminal has been rearranged, according to the present invention, the above-described process can be quickly performed through the virtual operating environment of the corresponding M2M terminal generated in the M2M server 30, thereby minimizing the time required for repair of an error-prone M2M terminal. Will be.

In addition, in the case of manufacturing the M2M terminal in the conventional case, the first manufacturer's test and the second operator's test can be carried out separately to ensure quality, and the manufacturing cost is reduced by omitting the first test process according to the present invention. At the same time, the operator test, which was conducted in the second stage, can be directly reflected in the development process of the manufacturer, thereby ensuring the quality of the M2M terminal and operating environment such as operating environment variable, natural environment variable, and user pattern variable compared to the existing test process. Test data for can be directly reflected in product development.
