Abstract

A method for activating a user device's service on the basis of state information is provided to enable a service provider, which provides contents through wire/wireless networks, to remotely maintain and manage the activation state of each user device according to its state information. If a consumer purchases a user device, which is in a "factory initialization" state, for the first time(S21), the purchaser side of the user device makes a connection request to a service provider's DMS(Device Management Server) by directly manipulating the user device or using URL information which is previously and basically stored in the memory(S22). The DMS accepts the user device's connection request(S23). The DMS acquires "./dEVLNFO/*", the basic information of the user device, and registers it with the connected URL address(S24,S25). Then the DMS sends an ACK message to notify the user device that registration has been completed, and changes this registration information into a preset management object value(S26). In this case, the user device becomes a "DMS registration" state.

The present invention relates to a method of activating a service of a user terminal based on state information. More particularly, the present invention relates to a method of activating a user terminal receiving content using a wired / wireless network and a procedure for maintaining and managing the same. The present invention relates to a service activation method of a user terminal based on state information suitable to be executed by a provider's remote control.

Recently, with the development of high-speed Internet, IT convergence, and media technologies, the spread of user terminals receiving various content services over wired and wireless networks has been activated. Representative types of user terminals include mobile phones, PDAs, IP-STBs, and media center PCs.

Conventionally, when a consumer purchases a service terminal provided with content on a network, the user terminal is in a factory initialization state which is commonly set when the product is initially shipped. Therefore, the user or the sales company of the user terminal accesses the server to the service provider that provides the content in a predetermined communication method, inputs necessary information requested by the service provider, performs the initial setup procedure accordingly, and the consumer desires Content can be provided.

However, the initial setting procedure of the user terminal is becoming more and more complicated due to the diversification of contents and the diversification and intelligence of programs using the contents. Therefore, it is a reality that consumers do not directly enter the initial setting procedure, and consumers are asking a group of experts such as a user terminal sales company, a telecommunication company, or a service provider.

In addition, even after the consumer initially sets and opens a purchased user terminal to receive content, the user terminal may be required to receive specific content or a program for executing the content, or to up-date the user terminal. The user terminal was maintained and managed by visiting or requesting a professional group such as a sales company, a telecommunication company, or a service provider.

If the service provider can activate the service of the user terminal remotely using the user information set at the time of purchase of the user terminal and maintain and manage it, it will be very convenient for the consumer.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an active state of a corresponding user terminal according to state information of each user terminal in a service provider that provides content using a wired or wireless network, and thus maintains the activated state of the corresponding user terminal. And it is to provide a service activation method of the user terminal based on the status information that can be remotely managed.

In order to achieve the above object, the service activation method of the user terminal based on the state information according to the present invention, a terminal management server of the service provider side providing specific content to a plurality of user terminals using a wired / wireless network Setting state information of the corresponding user terminal to a terminal management server (DMS) registration state; When the user terminal is a service activation management target of a service provider in the terminal management server, changing the state information management object value of the user terminal to a trust relationship registration state; And performing a service activation setting suitable for a user terminal in a trust relationship registration state using basic information of a user terminal connected from the terminal management server.

Here, the setting of the terminal management server (DMS) registration state may include requesting a connection to a terminal management server of a service provider that provides specific content using a wired / wireless network using a user terminal in an initial state; ; Registering a subscriber in the terminal management server using basic information of the user terminal; When the registration of the user terminal is successful in the terminal management server, it is preferable to change the state information according to the predefined management object value and set the user terminal.

In addition, the step of changing to the trust relationship registration state, the terminal management server (2) is the step of determining whether the user terminal service activation management target of the service provider; When the user terminal is the service activation management target of the service provider, the terminal management server preferably exchanges mutual credentials with the user terminal to form a trust relationship.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a communication system for explaining a service activation procedure of a user terminal based on state information according to the present invention.

Referring to FIG. 1, a plurality of user terminals 1a-1n such as a mobile phone, a PDA, an IP-STB, a media center PC, and the like are connected to a wired / wireless network 5, and the wired / wireless network 5 is a terminal. The service management system (DMS) (2), Subscriber Management System (SMS) (3), Service Activation Management System (Policy System: PC) (4) interworking with each other Connected.

Here, the terminal management agent (DMA) 1-1 of each user terminal 1 exchanges management information with the terminal management server 2 using a management protocol preset through the wired / wireless network 5. Or execute the given command.

In this case, the terminal management agent (DMA) 1-1 has a function of storing and managing a management object value in a parameter form according to the state information of each user terminal 1, and the user terminal 1 and the terminal management server. The management protocol used between (2) uses Simple Network Management Protocol (SNMP) or Open Mobile Alliance Device Management (OMA DM).

In addition, the subscriber information management system 3 stores service application information submitted or inputted by each user terminal 1 at the time of subscription in order to provide the latest service activation state to each user terminal 1, and service activation. The management system 4 defines and integrates and manages the necessary content, a program for executing the content, update information, or bug fix information, etc. according to the user terminal 1 or the service activation state.

Hereinafter, a service activation procedure of a user terminal based on state information according to the present invention will be described in detail with reference to FIGS. 1 to 3.

1 to 3, when a consumer initially purchases a specific user terminal 1a, the user terminal 1a that is purchased is set to an initial state in which service information desired by the user is set or user information is not input (S21). This is referred to as "factory initialization state" (S201 of FIG. 2).

Therefore, the purchaser side of the user terminal 1a directly operates the user terminal 1a in the factory initialization state, or uses the server information (URL) previously stored in the memory by default at the time of factory shipment. Request connection to (2) (S22).

The terminal management server 2 approves the access to the access request of the user terminal 1a which requested the access in step S22 (S23).

The terminal management server 2 acquires the basic information (./dEVLNFO/*) of the user terminal 1a inputted by the user terminal 1a at the time of connection (S24) and registers it with the accessed URL address (S25). .

Subsequently, the terminal management server 2 transmits an ACK message indicating that the registration is completed to the user terminal 1a, and simultaneously displays status information indicating that the user terminal 1a has been successfully registered. Change to the value set in advance in 1) and set (S26). Here, it is preferable that the management object managing the state information of the user terminal is defined as an essential parameter that is basically transmitted every time the terminal management server 2 managing the user terminal 1a is connected. By using this method, the terminal management server 2 can greatly increase the efficiency of acquiring the state value received from the user terminal 1a.

When the step S26 is completed in this way, each user terminal is in the "terminal management server (DMS) registered state" (S202 in Fig. 2). In such a DMS registration state, the terminal management server 2 may acquire a right to access some basic information of the user terminal 1 in its own area and execute a minimum remote diagnosis.

Subsequently, the terminal management server 2 inquires the profile information of the user terminal registered in advance in the subscriber information management system 3 in order to confirm whether the registered user terminal 1a is a service activation management target of the service provider ( S27).

The terminal management server 2 transmits a command to the user terminal 1a when it is determined whether the service provider of the service provider is managed by checking the profile information of the user terminal stored in the subscriber information management system 3. A trust relationship is established by exchanging credential values.

At this time, the registration URL used in step S22 is an open server that is allowed to access all the user terminal is a URL without a security function. Therefore, in order to protect the user terminal 1a and the terminal management server 2 from intentional intrusion through the network in the future, the URL used for access by the user terminal in the future in the relationship of trust formation is changed to the general service URL (S28). .

If such mutual authentication (credential) value exchange and URL change are successfully executed, the terminal management server 2 sets the status information management object value of the terminal management agent 1-1 of the user terminal 1a to " trust relationship registration. State "(S203 in Fig. 2).

Therefore, when the user of the user terminal 1a accesses the terminal management server 2 using the management URL address received from the terminal management server 2 (S29), the terminal management server 2 connects Using the basic information of the user terminal, a service activation setting suitable for the corresponding user terminal registered in the service activation management system (PS) 4 is executed (S30) (S204 in FIG. 2).

Here, the service activation setting refers to a procedure for setting provision or upgrade of essential information (eg, a server URL, an account) and essential software for using a service provided with predetermined content requested by a user.

Subsequently, when the user terminal 1a is rebooted or connected to the terminal management server 2 using a management URL having a security function according to a predetermined service provider's provision such as service activation management expiration (S31), the terminal management server (2) compares the current setting state of the corresponding user terminal with the latest state registered in the service activation management system 4 and executes the synchronization operation (S32).

Therefore, each user terminal 1 can always maintain the best service activation state by remote operation of the service provider side, so that the latest service provided by the service provider can be provided.

FIG. 4 is a hierarchical structure diagram of a state management object (DDF) of a user terminal in the OMA DM protocol used by the user terminal 1a and the terminal management server 2 illustrated in FIG.

1 and 4, in the OMA DM standard, a DevInfo node having minimum information of the user terminal 1a in state management information, and a DMAcc node for establishing a trust relationship between the user terminal 1a and the terminal management server 2 The terminal has additional nodes, DevDetail, and other vendor definitions.

In particular, the DevInfo node is a node that should be taken by default in every packet when the user terminal 1a accesses the terminal management server 2.

As such, when each user terminal 1a accesses the terminal management server 2, the basic information of the user terminal 1a is provided, so that the terminal management server 2 obtains the basic information of the user terminal 1a. The overhead on the protocol / network for reconnecting to terminal 1a can be reduced.

In addition, in the system using SNMP, which is commonly used as a management standard, conventionally, information corresponding to DevInfo is customized as contents of a user-defined PDU (Packet Data Unit) in a trap packet to create the structure shown in FIG. 4. In addition, it may take a method of transmitting in addition.

That is, in the factory initialization step (S201) of FIG. 2, the registration URL of the terminal management server 2 is stored under AppAddr. When the network is activated based on this, the corresponding user terminal 1a is connected to the terminal management server 2. Done.

 In addition, the user terminal 1a has DevInfo information as payload information when a connection request is made. At this time, in the embodiment of the present invention, a managed object called ./DevInfo/Ext/ProvStat is defined and used as an extension node in DevInfo, and the location or name of the node is not limited to the contents of the embodiment of the present invention.

In addition, the ProvStat value is state information of the user terminal 1a and may set a value of whether the current state of the user terminal 1a is a factory initialization state.

If the ProvStat value in the user terminal 1a is a value according to the factory initialization state, the terminal management server 2 additionally adds an additional value necessary for registration of the status management service for the user terminal 1a. ).

At this time, if the user terminal 1a is successfully registered in the terminal management server 2, first, the management object value is changed to the registered state as a result of successful registration in the user terminal 1a.

As the user terminal 1a is exposed to the network, the necessity of security of the management session is very high for the purpose of malicious virus intrusion or hacking and content protection. Accordingly, after successfully registering with the terminal management server 2, the terminal management server 2 will then exchange information with the subscriber information management system to form a trust relationship.

In addition, the terminal management server 2 does not use the registered URL address, but sets a management URL address having a security function in the user terminal 1a for use of the status management service.

Here, the management URL address is an example of a server address, and may be a separate management server address and the like physically and logically divided.

When the setting process is completed, the terminal management server 2 changes the ProvStat value of the corresponding user terminal 1a to a value according to a trust relationship formation state.

Up to this point, the user terminal 1a subsequently accesses the management URL address based on the security information, and receives the latest information specific to the user.

In addition, since the following necessary operations are known between the user terminal 1a and the terminal management server 2 based on the ProvStat information, if the service activation procedures described above are not executed sequentially for a specific reason, the following steps are executed. Because of this, the entire service activation process can be managed efficiently.

As described above, according to the service activation method of the user terminal based on the status information according to an embodiment of the present invention, the service provider for providing content using a wired or wireless network corresponds to the status information of each user terminal. The activation state of the user terminal and thus maintenance and management can be executed remotely.

Through the service activation method of the user terminal based on the state information according to the present invention, it is possible to protect against intentional intrusion that may occur during the service activation of the user terminal, and the user terminal state management can be expanded to be effective even in an unstable network situation. Enable service activation.

The service activation method of the user terminal based on the state information according to the present invention described above is not an open service providing model through a portal, but a semi-closed broker type service providing model through an open service brokerage provider platform, for example Cotton, IP-TV, mobile service, etc.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
