In the drawings, like reference numerals are used to denote like elements in the drawings, even if they are shown in different drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a block diagram of a system for managing a remote terminal based on a communication network according to an embodiment of the present invention. As shown in the figure, a communication network 10, an over-the-air (OTA) server 20, (30), and a Home Subscriber Server (HSS).

The communication network 10 connects the over-the-air (OTA) server 20, the subscriber terminal 30, and the HSS (Home Subscriber Server) by wire, wireless, and / Alone or a composite communication network. In this embodiment, an LTE network including an MME (Mobility Management Entity) 11 will be described as an example.

The OTA server 20 is an OTA (over-the-air) service, and the OTA service is the most common type of wireless communication service for transferring data requested by a subscriber. The OTA service is a service to transmit data requested by the subscriber to the communication terminal of the subscriber from the OTA server 20 of the service customer center when the subscriber requests data such as subscriber information or application program to the OTA server 20 of the service customer center . The subscriber can receive desired data at his / her communication terminal using the OTA service, and the operator can transmit various data to the communication terminal using the OTA service.

The subscriber terminal 30 includes a mobile communication terminal, a smart phone, an M2M device, an IoT device, and the like which are equipped with a Universal Integrated Chip Card (UICC) and can perform voice communication, video communication, message communication, data communication, .

The HSS 40 is a server for subscriber / terminal information management, location registration, and the like. In this embodiment, when the HSS 40 registers a location, the subscriber terminal 30 transmits a specific terminal Quot;) to the OTA server 20. The OTA server 20 may provide information to the OTA server 20. [

FIG. 2 is a detailed configuration diagram of a server for managing a remote terminal based on a communication network according to an embodiment of the present invention, which is applied to the OTA server 20 of FIG. 1, for example. A server connection request unit 23, a download unit 25, a storage unit 27,

The UE confirmation unit 21 receives a ULR (User Location Request) message as a registration request message from the MME 11 according to an attempt to access the LTE network 10 from the subscriber terminal 30, for example, (E.g., IMSI, IMEI, etc.) in the mobile terminal is information about the terminal before opening. If it is the terminal information before opening, the subscriber terminal 30 confirms whether the terminal is an LTE only device Another example is to change the terminal data from the business computer server IT, operator, service provider or the like to the subscriber terminal 30 that has been connected to the LTE network 10 It is possible to confirm whether the subscriber terminal 30 is an LTE only device by communicating with the HSS 40 when the terminal management request message for the subscriber terminal 30 is received.

When the subscriber terminal 30 is confirmed as an LTE only device through the terminal confirmation unit 23, the server connection request unit 23 transmits a profile request for profile provisioning, remote application management of the terminal, (MME) 11 to a corresponding subscriber terminal 30 for a remote device management including at least one of a server connection request message and a file management (Remote File Management) May include a Downlink NAS Transport message.

The download unit 25 accesses the connected subscriber terminal (or UICC) 30 when the subscriber terminal 30 is connected based on the server connection request message transmitted through the server connection request unit 23, Data for device management is downloaded for data management. The data for remote device management includes profile provisioning data, remote application management data of the terminal, And Remote File Management data, and the download message may include a Hyper Text Transfer Protocol (HTTP) message.

The storage unit 27 stores the first terminal number information to be used for the new subscriber and the second terminal number information to be used after the opening, for example, from the sales data server 60, The number information may include pseudo-IMSI information as information on a telephone number of a subscriber terminal to be temporarily used before the opening, and the second terminal number information may include an IMSI Subscriber Identity) information.

The recognition unit 29 determines whether or not the terminal number information in the registration request message generated due to the registration request from the subscriber terminal 30 matches any of the first and second terminal number information stored in the storage unit 27 It is therefore necessary to recognize the necessity of opening.

In this case, when the HSS 40 recognizes the necessity of opening, it transmits an opening request message to the OTA server 20, and the OTA server 20 transmits the opening request message to the OTA server 20 It is possible to recognize the necessity of opening.

FIG. 3 is a flowchart of a method for managing a remote terminal based on a communication network according to an embodiment of the present invention, and is a flowchart for profile provisioning of a remote activation profile based on an LTE network and is applied to the apparatuses of FIGS. 1 to 2 The operation of the apparatus will be described in parallel.

When a customer requests to open a new USIM to a telephone number requested by a new subscriber or a USIM replacement, the business computing server (IT) can use the remote wakeup system of the network (NW) such as the OTA 20 The OTA 20 prepares the subscriber information including the IMSI profile (for example, the first terminal number information) before the opening and the subscriber information including the telephone number Profile (for example, the second terminal number information) to be used after the opening (S302).

After the USIM (or UICC) is inserted into the terminal 30 before power-up, the UICC / UE 30 transmits the first terminal number information to the LTE network 10, (MME-Number-for-MT-SMS, etc.) and the first terminal information IMEI (S303) And transmits an ULR message as a request message to the OTA 20 (S304). Here, the OTA 20 can perform the role of the HSS.

The OTA 20 can deliver an APN list necessary for opening based on the IMEI information transmitted from the MME 11 or deliver an APN list necessary for opening defined before checking the IMEI information. The OTA 20 transmits an SMS in MME-related profile to the ULA message and transmits it to the MME 11. That is, in step S304, the OTA 20 transmits an APN list (for example, OTA) to the MME 11 based on the International Mobile Equipment Identity (IMEI) information transmitted through the ULR (User Location Request) message from the MME 11 of the LTE network (Access information) to the MME 11 of the LTE network through a ULA (User Location Answer) message, or transmits an APN list required for the predefined opening to the MME 10 without checking the IMEI information (S305) , The MME 11 transmits an Attach Accept message to the terminal 30, and the terminal 30 succeeds in accessing (acquiring) the LTE network (S306).

After the successful acquisition of the LTE network, the OTA 20 performs Pseudo-IMSI range check (IMSI information) which defines in advance whether the subscriber is a subscriber requiring opening based on the terminal number information (IMSI) included in the ULR message of step S304, (First terminal number information). If the subscriber terminal 30 is a subscriber requiring opening, the device capability is confirmed with the IMEI information received from the MME 11. If the subscriber terminal 30 is an LTE Only device, The MME 11 transmits a MT Forward Short Message Request (TFR) message to the MME 11 in response to the TFR message from the MME 11 (S308) .

In this embodiment, since the OTA 20 can perform the role of the HSS (providing the S6a interface function), it does not send the S6c message to the HSS (Send Routing Info for SMS Procedure) Message can be transmitted.

Then, the MME 11 transmits OTA connection request information for opening to the subscriber terminal 30 in a Downlink NAS Transport message (S309). In this embodiment, the NAS message in step S309 is used for a trigger for the HTTP connection. However, if the size of the opening data is small, the NAS message in step S309 can be transmitted with the opening data .

If the NAS message is used for triggering in step S309, the OTA 20 transmits a service ID including a predefined service ID to the subscriber terminal (or the UICC) 30 for the data to be downloaded by the OTA 20.

The USIM 30 then attempts to make an HTTP access request to the OTA 20 based on the NAS message received from the OTA 20 via the MME 11 and then at step S309 the OTA 20 And transmits the service ID included in the HTTP message (S310).

Returning the service classification ID in the terminal Trigger message to the OTA without changing in the terminal (USIM) as shown in step S310 may facilitate service scalability.

The OTA 20 determines whether it is a request for downloading the opening data based on the service category ID in the HTTP message received from the subscriber terminal (USIM) 30, and downloads the corresponding opening data to the subscriber terminal (USIM) 30 S311).

When the subscriber terminal (USIM) 30 completes the opening of the new number (S312), the subscriber terminal (30) attempts to access the network with the changed number (S313).

FIG. 4 is a flowchart of a method for managing a remote terminal based on a communication network according to another embodiment of the present invention. FIG. 4 is a flowchart for remote terminal management based on an LTE network and is applied to the apparatus of FIGS. The operation of the apparatus will be described in parallel.

When the subscriber terminal (UICC / UE) 30 is successfully connected to the LTE network and is registered in the HSS 40 (S401), the OTA 20 is connected to an external business computer IT, a network operator, (S402), the subscriber terminal 30 transmits a SPR / SPA message to the HSS 40 (S403). When the subscriber terminal 30 receives the terminal management request message from the service provider (S402) (S404) whether the terminal 30 is a specific terminal capable of only LTE services.

For example, in step S402, when the network operating network operator needs to change the device data (e.g., PLMN) for network operation or service provisioning, or when the service provider needs to change device data, device data provisioning. In this embodiment, the device data change may include Remote File Management, Remote Applet Management, and the like.

In step S403, the OTA 20 transmits / responds to the HSS 40 and the SPR / SPA message for transmission of a NAS message for device data provisioning. In this case, the HSS 40 transmits / Information to the OTA 20 in a SPA message.

If it is determined in step S404 that the subscriber terminal 30 is an LTE only device, the OTA 20 transmits a server connection request message for device management to the corresponding subscriber terminal 30 through the MME 11, (S405 to S407).

For example, the OTA 20 transmits a MT Forward Short Message Request (TFR) message to the MME 40 in step S405, and the MME 40 transmits an MT Forward Short Message Answer (TFA) message to the OTA 20 After transmitting the TFR message (S406), the downlink NAS transport message is transmitted to the subscriber terminal 30 (S407).

In step S407, when the NAS message is used as a trigger, the OTA 20 transmits the service ID included in the TFR message and the NAS message to the terminal (USIM) 30 or the application in advance , The service classification ID is for data classification that the OTA 20 should download to the subscriber terminal 30.

The process of steps S405 to S407 described above is an example of the case where the size of the device data is large and the NAS message is used as a trigger for the HTTP connection as in the case of the specific applet delete of the UICC. If the size of the device data is small, the corresponding device data can be immediately transmitted to the TFR message and the NAS message in steps S405 to S407.

Subsequently, the subscriber terminal (USIM) 30 attempts to request a Hyper Text Transfer Protocol (HTTP) connection to the OTA 20 while processing the NAS message received from the OTA 20 via the MME 11, In the above-described process, the service classification ID received from the OTA 20 is included in the Hyper Text Transfer Protocol (HTTP) message and transmitted (S408). The service classification ID in the terminal Trigger message can be easily extended to service extensions by returning to the OTA without modification at the terminal (USIM).

Finally, the OTA 20 downloads device data (i.e., remote terminal management data) corresponding to the service ID in the HTTP message received from the subscriber terminal (USIM) 30 to the subscriber terminal 30 in step S408.

As described above, the method for managing a remote terminal based on a communication network according to an embodiment of the present invention can be implemented as a computer-readable recording medium including program commands for performing various computer-implemented operations. The computer-readable recording medium may include a program command, a local data file, a local data structure, or the like, alone or in combination.
