Description

[0001] The present invention relates to a method and apparatus for registering a device in an M2M network via a gateway,

The present invention relates to a method and a gateway device for registering a plurality of M2M devices on an M2M network and more specifically to a method and a gateway device for registering a plurality of M2M devices on an M2M network through an M2M gateway .

The development of modern information and communication technology is changing not only for computers but also for networking of smart phones and portable multimedia devices. Small devices such as computation and communication networking functions used in such computers, smart phones, and the like enable a communication network between objects that are used not only in information devices but also in various objects around human beings to acquire information around them and share them with each other.

One of such technologies is Machine to Machine (M2M) communication. M2M is a technology related to the networking of devices and devices that are widely used in everyday life. M2M communication enables a series of devices to be connected and used from the computer mainframe to everyday products (eg, home appliances, buildings or transportation).

The M2M communication is a concept to construct a network using a small communication device in the M2M device and to share collected information. It started from USN (Ubiquitous Sensor Network), which mainly targets local area without human intervention, As range and purpose vary, various wired / wireless networks can be used for M2M communication. This M2M communication uses low-cost, low-power short-range wireless communication such as Zigbee, Bluetooth, WiFi, etc. and uses cellular-based high-speed mobile communication technology such as 3GPP and LTE for various convergence services such as situation recognition, It is possible.

The M2M network is based on the European Telecommunication Standards Institute (ETSI) standard implementation. According to the ETSI standard, a method of connecting to a network area of an M2M device includes a 'direct connection method' in which an M2M device directly connects directly to an M2M network, and an M2M device is used as a network proxy, And 'indirect connection method' that connects to the network.

1 is a diagram illustrating an example of a structure of a communication system using a general M2M network.

Referring to FIG. 1, the M2M communication system 100 transmits data transmitted from the device area 101 and the M2M devices 111 and 112, which are composed of M2M devices 111 and 112 and / or M2M gateway 113, And a network area 102 composed of a transmission network 114 for delivering through a communication network and an M2M application 115 associated with a transmission network.

At this time, the network area 102 manages the M2M network and manages the configuration, the failure, and the subscriber management of the M2M network. The network manager 116 performs network configuration management, fault management, subscriber management and performance management, And an M2M management unit 117. [

The M2M device area 101 is composed of a direct communication type M2M device 111, an indirect communication type M2M device 112 and an M2M gateway 113.

The direct communication type M2M device 111 includes an M2M function unit 111a and an M2M application unit 111b and can perform one or more application applications through a communication function and directly connect to the M2M network.

On the other hand, the indirect communication type M2M device 112 corresponds to the device using the M2M area network and is for distinguishing the direct communication type M2M device 111 from the direct communication type M2M device 111. For example, equipment used for health care, remote equipment such as offline payment (payment using a card or a smart card), or payment terminal for mobile payment (payment using a smart phone). The indirectly communicating M2M device 112 is indirectly connected to the M2M transmission network 114 via the M2M gateway 113 and to the M2M gateway 113 via the M2M local network which is distinct from the M2M network.

Specifically, the indirect communication type M2M device 112 does not directly access the M2M network and does not include a separate M2M function unit or an M2M application unit, so that it can access the network through a separate gateway or router. That is, the M2M gateway 113 acts as a network proxy for indirectly connecting the indirectly-communicating M2M device 112 to the transmission network 114. [

The M2M gateway 113 connects the indirectly communicating M2M device 112 to the access network 114a via the M2M local network. To this end, the M2M gateway 113 includes an M2M functional unit 113a and an M2M application unit 113b. The M2M gateway 113 connects the indirect communication type M2M device 112 connected through the M2M local network to the access network 114a, Routing, and communication functions. In addition, the M2M gateway 113 can collect device operation data, environment data, sensing data, and the like from the indirect communication type M2M device 112 and transmit it to a remote operation server.

In this manner, the direct communication type M2M device 111 and the M2M gateway 113 provide functions such as data collection and reporting, remote control function, group communication or one-to-one communication function, and transaction processing in order to provide M2M service.

The M2M local network is a network for connecting the indirect communication type M2M device 112 and the M2M gateway 113. The network configuration, communication processing, management, maintenance, and maintenance for ensuring smooth sensing and driving functions of the device are independent , And data processing is performed in the local network.

Local networks include personal area network (PAN) such as IEEE 802.15, ZigBee, Bluetooth, RFID, automotive communication technology, industrial network, building automation communication technology, and communication technology used for home automation.

The transmission network 114 includes an access network 114a, a core network 114b, and an M2M service capability 114c associated with the M2M network access of the M2M device.

The access network 114a is a network configured to access various devices in a communication network in the M2M communication, and includes a wired access network and / or a wireless access network.

In recent years, M2M communication using wireless communication has been mainly performed. The wireless access network includes WCDMA (Wideband Code Division Multiple Access), WiMAX (Worldwide Interoperability for Microwave Access), WiFi (Wireless Fidelity) Can be used.

The core network 114b is a high speed backbone network of a large communication network capable of a large capacity, long distance voice and data service and is connected to a public switched telephone network (PSTN), an integrated information network (ISDN), an IMT-2000, a wide area network (WAN) LAN), and general cable broadcasting (CATV). It mainly uses the Internet backbone network, connecting the Internet, controlling services and networks, providing interconnection and roaming with other networks.

The access network 114a and the core network 114b serve as a transmission network for data communication between the M2M transmission network 114 and the M2M application 115 and the M2M devices 111 and 112, .

The M2M service capability 114c identifies and stores information for providing application functions, performs communication selection, remote object management, security, transaction management, and interworking, and configures the M2M core together with the core network 114b do.

The M2M application 115 performs operations related to the execution of application programs related to various services that can be provided to the M2M device, So that the connection using the network is performed.

If the 'direct connection method' is used in the M2M communication system shown in FIG. 1 as in the direct communication type M2M device 111, the M2M device 111 can perform authentication, authorization, management, And perform the same function.

On the other hand, when the 'indirect connection method' is used like the indirect communication type M2M device 112, the M2M device 112 is connected to the transmission network 114 through the gateway 113, 112, and network provisioning, authorization, and management provisioning.

According to the indirect connection method, in which a device registers indirectly through a gateway, unlike a direct connection method in which the device directly connects to the M2M network, the process of registering the devices in the network takes a number of steps.

FIG. 2 is a flowchart illustrating a process of a device performing communication with a network on a general M2M network. Specifically, FIG. 2 illustrates a process of registering an indirect communication type M2M device in the M2M network.

Referring to FIG. 2, the M2M device registers an application with a Gateway Service Capabilities Layer (GSCL) in a gateway through a Device Service Capabilities Layer (DSCL) in the device (S201).

According to the registration, the GSCL of the gateway performs local communication with the M2M device through the M2M local network and performs local communication with the Network Service Capabilities Layer (NSCL) of the network through the M2M network (S202).

Separately, the M2M network performs a bootstrap process and a predetermined network registration process (S203), and performs a bootstrap and service connection process for a service provided to the M2M devices (S204).

The NSCL of the network configures the GSCL context with respect to the GSCL of the gateway connected through the local communication, and registers the DSCL or the GSCL in the NSCL (S205).

2, steps S201 and S202 correspond to a connection procedure (first connection) between a device and a gateway, and steps S203 to S205 correspond to a connection procedure (second connection) between a gateway and a network.

As each connection process is completed, the M2M device can be registered on the M2M network through the gateway, and specifically, the M2M device can be connected to the NSCL to perform mutual data communication (S206).

2, in order to connect a new M2M device to the access network through the M2M gateway, it is possible to register the new M2M device through a network bootstrap. In the network registration process, instead of the NSCL, And the process of authorization charging. Then, in order for the M2M device to connect to the NSCL through the gateway, the gateway performs the mutual authentication with the NSCL in the process of connecting the service through the service bootstrap. Also, in order to exchange the device configuration information of the M2M device with the NSCL, the M2M gateway performs the service capability layer (SCL) registration procedure of the NSCL.

Accordingly, when a plurality of indirect communication type M2M devices register with the M2M network and perform data communication with the NSCL, the gateway performs the process illustrated in FIG. 2 for each M2M device.

3 is a diagram illustrating a process in which a plurality of M2M devices are registered in the M2M network through a gateway.

3, when n M2M devices 301 register an application in the M2M gateway 302 and the gateway 302 registers n devices 301 in the M2M network, that is, the NSCL 303, , The gateway 302 performs the n network registration process, the n service connection process, and the n SCL registration process with the NSCL 303.

In the N network registration process, N number of IP address assignment, authentication, authorization, and billing procedures are performed. In N number of service connection processes, N number of mutual authentication procedures are performed. In N number of SCL registration processes, N number of device configuration information exchange procedures .

When a plurality of M2M devices are registered in the M2M network through the gateway, network communication resources are wasted in the process of data communication between the M2M device and the NSCL, and data loss occurs in the process of exchanging the device configuration information in the SCL registration process Potential problems may arise in providing M2M services.

Accordingly, various methods for minimizing the process of registering a plurality of devices on a network have been researched.

For example, in the case of "authentication system of home device and its authentication method (Application No. 10-2003-002091)" of the related art, when one device is authenticated in one home network domain, it moves to another home network domain A method for simplifying the device registration process by sharing information between a home gateway in which a device is registered and another home gateway in order to solve problems of management occurring in a device authentication process and increase in management cost in a certification authority I am suggesting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following detailed description, together with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced. The following detailed description includes specific details in order to provide a thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention may be practiced without these specific details.

The present invention relates to a method and system for registering a plurality of M2M devices on an M2M network. Specifically, in order to solve a problem of service failure due to waste of network resources and loss of data in a plurality of M2M device registration and authentication processes, the M2M gateway transmits a plurality of M2Ms to the M2M network based on the device and network information received from the network management server A method and system for registering a device are proposed.

4 is a diagram illustrating an example of a system structure for registering a plurality of M2M devices based on an M2M gateway according to an embodiment of the present invention as an M2M network.

Referring to FIG. 4, a system 400 according to an embodiment of the present invention includes a management server 410 of an M2M network area, an M2M device 420 and an M2M gateway 430 of a user area. Here, the M2M device 420 corresponds to an unregistered device on the M2M network, and network registration is requested to use the M2M communication.

The management server 410 sends the device configuration information to the M2M gateway 420 to the M2M device 420 to be newly registered and the M2M gateway 430 transmits the device configuration information to the M2M device 420 registered in the M2M gateway 430 And registers it in the M2M network system based on the device configuration information received from the management server 410. [

To this end, the M2M gateway 430 includes a wireless communication unit 431 for performing wireless communication with the M2M device 420 and the management server 410, data for storing device configuration information transmitted from the management server 410, A storage unit 432, and a control unit 433 for performing overall control operation on the gateway and determining whether to register on the network of the device based on the device configuration information received from the M2M device 410. [

The wireless communication unit 431 allows the gateway 430 to perform wireless data communication with the M2M device 420 or the management server 410 through the local network or the M2M network.

The data storage unit 432 stores and updates one or more M2M device configuration information or user identification information received from the management server 410 through the wireless communication unit 431. The control unit 433 then stores Provide the necessary data to perform the registration authentication procedure. The M2M device configuration information may include new device information, network identification information, and user identification information.

The controller 433 controls operations and functions of the M2M gateway 430 in general. Specifically, the controller 433 controls the connection to the M2M network side of the gateway 430, the M2M device configuration Provision of information, application registration of the connecting M2M device 420, and network registration proxy.

The control unit 433 includes a comparison and analysis unit 433a that compares configuration information transmitted from the M2M device 420 with information previously received from the management server 410 to determine whether the information is a legitimate object, And a registration / authentication unit 433b for performing a procedure.

When the M2M device 420 is connected to the gateway 430, the comparison and analysis unit 433a verifies the information about the connected M2M device 420 in the network registration process and stores the information and the information stored in the data storage unit 432 Compare and analyze device information.

When the information of the M2M device 420 matches the information of the device transmitted from the management server 410 according to the analysis result of the comparison / analysis unit 433a, the registration / (IP address, etc.) of the network. On the other hand, when the pieces of information do not match, the network registration of the M2M device may be blocked or limited network identification information such as a private IP address may be allocated. In addition, the registration / authentication unit 433b may perform an authentication procedure and a user authentication procedure with respect to the M2M device 420. [

The control unit 430 may register the connection information to the system by notifying the management server 410 of the configuration information about the device 420 after performing the registration and authentication procedure for the M2M device 420. [

As described above, when the M2M gateway according to the embodiment of the present invention is used, even if the network management server 410 does not perform a registration and authentication procedure for directly registering the M2M device 420, 421) is registered. Also, as a network registration

The gateway 422 not only registers the device application with the GSCL, but also directly registers the network based on predetermined device configuration information, thereby assigning the network identification information to the registered M2M device 421 so that the device can perform data communication .

The device registration for the M2M network through the gateway according to the embodiment of the present invention described with reference to FIG. 4 will be described with reference to FIG. 5 to FIG.

5 is a flowchart illustrating an example of a device registration process in a network registration system of an M2M device using a gateway according to an embodiment of the present invention.

5, a gateway according to an exemplary embodiment of the present invention registers a gateway with a network management server. Specifically, a GSCL registered with a gateway application (GA) is registered with a NSCL registered with a network application. (S501).

After the connection between the GA and the GSCL and the connection between the GSCL and the NSCL are completed, the GSCL and the NSCL are communicated, and the GSCL and the NSCL can exchange the mutual device configuration information.

For example, the management server may store and manage information about at least one or more M2M devices that are currently in the unrecorded state, scheduled to be used, or usable in a predetermined database, and the information about the M2M device may be stored in the predetermined database in association with the device configuration information and the user And identification information.

The management server derives configuration information on one or more M2M devices included in the management category of each gateway based on the information of the registered gateway based on the database, and transmits the configuration information to the gateway (S503). The configuration information on the M2M device may include at least one of device identification information, device configuration information, user identification information, and network identification information (e.g., public IP address, private IP address, etc.).

The steps S501 to S503 show the SCL registration process.

Through the SCL registration process, the management server transmits the M2M device configuration information to the gateway, and the gateway provisions the received M2M device configuration information (S504).

Thereafter, when a new M2M device in an unregistered state enters the M2M network system, the new M2M device registers DSCL in the GSCL of the M2M gateway (S505). For example, when a user purchases a new M2M device and drives a predetermined function using the M2M network, a new M2M device that is not registered in the M2M network system enters the device, and the device transmits the SCL registration to the gateway detected by the user input signal Can be performed.

As the DSCL of the new M2M device registers with the GSCL of the gateway, the gateway confirms the connected M2M device information and compares it with the M2M device configuration information provisioned in the previous step (S504) (S506).

As a result of the comparison, when the M2M device configuration information transmitted from the management server matches the new M2M device information connected thereto, the gateway derives the network identification information corresponding to the device identification information based on the device configuration information and assigns it to the new M2M device (S507). &Lt; / RTI > As described above, the network identification information may correspond to a network ID such as a public IP address or a private IP address.

On the other hand, if the connected M2M device information does not match the new M2M device configuration information as a result of comparison, registration of the corresponding M2M device may be blocked or private network identification information such as a private IP address may be allocated (S508).

When the network registration of the new M2M device in the gateway is completed, the gateway notifies the registered new M2M device configuration information to the management server and bind the connection information (S509).

For example, the gateway notifies the management server of the device configuration information in real time by registering the new M2M device, or may notify the management server of the device configuration information periodically or non-periodically at predetermined intervals.

Notification of new M2M device configuration information corresponds to SCL registration update.

After the registration of the M2M device, the gateway registration process of the application in the device is performed.

Next, the gateway determines whether or not the predetermined M2M service provided by the gateway of the M2M device is allowed to be used. If the M2M device configuration information matches the M2M device information and the service status information stored in the gateway, In the GSCL of the gateway (S510, S511).

After completing the registration of the device application, the gateway notifies the device configuration information to the management server and update the SCL registration for the changed items (S512).

According to an embodiment of the device registration process illustrated in FIG. 5, the gateway according to the embodiment of the present invention reserves device configuration information and user authentication information in advance for network registration, The communication procedure between the gateway and the management server can be minimized.

On the other hand, when the user tries to connect to the M2M network using the M2M device not pre-registered in the M2M system, or when the user holds the first M2M device using the first M2M service, Or a situation where a user tries to connect to the first gateway and connect the M2M device in use to the second gateway to which another user's device is connected.

That is, according to the embodiment of the present invention, since the gateway performs the device registration on behalf of the network management server, it is necessary to manage not only the device to be managed by the gateway but also the devices that are out of the management target. For example, when a new M2M device to which a gateway has not received information from a network node is connected, the gateway can manage the corresponding M2M device in an unregistered state even if the corresponding M2M device is registered in a network terminal through another gateway .

A method of connecting the M2M device, which uses a service other than the currently registered service, or a service unused state to the network as described above will now be described with reference to FIG.

FIG. 6 is a flow chart illustrating another example of a device registration process in a network registration system of an M2M device using a gateway according to an embodiment of the present invention. More specifically, when a user selects an unused M2M service registered in the M2M device The device network registration method will be described.

Referring to FIG. 6, a series of SCL registration processes (S601 to S603) for registering an M2M device as an M2M network through a gateway is the same as the SCL registration process (S501 to S503) described above with reference to FIG.

When the SCL registration process is completed, the gateway provisions the M2M device configuration information received from the management server (S604).

Thereafter, when an unregistered M2M device enters the M2M network system, for example, when the user connects to the first gateway and tries to use the M2M device in use by connecting to the second gateway, the second gateway receives the M2M device from the management server The received M2M device configuration information does not include information related to the M2M device, so that the corresponding M2M device can be managed as an unregistered device.

The gateway compares and verifies the M2M device information based on the M2M device configuration information provisioned in the previous step (S604) with respect to the M2M device that registered the DSCL with the GSCL of the M2M gateway (S605, S606).

If it is determined that the gateway device is included in the device configuration information provisioned by the M2M device to be connected, the gateway performs network registration through network identification information (S607). However, even if the corresponding M2M device is included in the device information transmitted from the management server, the corresponding M2M device may not be managed by the gateway. Accordingly, in this case, whether the application is registered or not is determined according to whether the service is used or not.

Similarly, if the M2M device is determined to be not included in the device configuration information, the gateway may provide limited network identification information such as blocking network registration or assigning a private IP address (S608).

When the network registration of the new M2M device in the gateway is completed, the gateway notifies the registered new M2M device configuration information to the management server and bind the connection information (S609).

Next, the gateway determines whether or not the M2M service of the M2M device is used. According to the above-described embodiment, when the M2M device registered in the network does not use the M2M service provided by the gateway (i.e., (Step S610), the gateway may block the application registration of the M2M device (step S611).

Accordingly, the user can block other users' devices from accessing their own gateways, and the gateways can determine whether or not the other user's devices are authorized, thereby reducing the number of unnecessary communications between the gateway and the network.

Further, the device registration method using the gateway according to the embodiment of the present invention can be applied to the case of additionally purchasing an M2M device using the same M2M service while the user uses a predetermined M2M service through the registered M2M device have.

FIG. 7 is a flowchart illustrating another example of a device registration process in a network registration system of an M2M device using a gateway according to an embodiment of the present invention. More specifically, Method.

Referring to FIG. 7, a series of SCL registration processes (S701 to S703) for registering an M2M device as an M2M network through a gateway is the same as the SCL registration process (S501 to S503) described above with reference to FIG.

However, in the process of registering the GSCL of the gateway with the NSCL of the network management server and exchanging the configuration information (S701), not only a device information list including configuration information on a plurality of M2M devices but also a plurality of user information May also be interchanged.

When the SCL registration process is completed, the gateway provisions the list of the M2M device information and the list of the user information received from the management server (S704).

Thereafter, in step S705, a smart card capable of displaying user identification information such as a UICC (Universal IC Card) is attached to the new M2M device purchased by the user, or the gateway is connected with the phone number registration.

Here, it is assumed that the new M2M device is for additionally registering the registered M2M device with the same M2M device as the M2M device that the user has previously registered with the management server and used the predetermined M2M service. Hereinafter, do.

The gateway confirms that the additional M2M device connected to the gateway is an unregistered device according to the user request signal based on the provisioned M2M device information list, and notifies the additional M2M device that it is not registered (S706).

In step S705, the additional M2M device transmits a registration request message requesting device registration to the gateway together with the user identification information and the device configuration information set in the device in step S707.

In step S708, the gateway determines whether it matches the user identification information transmitted from the additional M2M device based on the user information list received from the management server in step S701.

If the user information received from the management server matches the user information of the additional M2M device according to the determination result, the gateway performs application registration of the additional M2M device (S709). Accordingly, the additional M2M device can be connected to the network management server through the gateway and use a predetermined M2M service.

The gateway can notify the management server of the device configuration information as the device application registration is completed (S710). At this time, the gateway can notify in real time according to the device application registration, or collect and notify one or more device configuration information registered in a predetermined period.

On the other hand, if the user information does not match, if the gateway is confirmed to be included in the device configuration information provisioned by the M2M device to which the connection is to be made, limited network identification information such as a network registration is blocked or a private IP address is assigned (S711).

According to the embodiment illustrated in FIG. 7, the user can connect the M2M device to the gateway more conveniently through the automatic registration procedure of the self-purchased M2M device by the M2M gateway, and can more conveniently use the M2M service .

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present invention are not intended to limit the scope of the present invention but to limit the scope of the present invention. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents thereof should be construed as being included in the scope of the present invention.
