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

The communication network 10 connects between the Over-The-Air (OTA) server 20, the subscriber terminal 30, and the Home Subscriber Server (HSS) through wired, wireless and/or the Internet to enable mutual communication. It may be a single or complex communication network, but in this embodiment, an LTE network including a Mobility Management Entity (MME) 11 will be described as an example.

The OTA server 20 is to provide an over-the-air (OTA) service, and the OTA service is the most common form of a wireless communication service that transmits data requested by a terminal subscriber. The OTA service is a service that transmits the requested data from the OTA server 20 of the service customer center to the subscriber's communication terminal when a subscriber applies for data such as subscriber information or an application program to the OTA server 20 of the service customer center. . A subscriber can receive desired data through his or 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 is equipped with a UICC (Universal Integrated Chip Card) to enable voice communication, video communication, message communication, data communication, and/or Internet communication, etc. A mobile communication terminal, smart phone, M2M device, IoT device, etc. indicates.

The HSS 40 is a server for subscriber/terminal information management, location registration, etc., and in this embodiment, the HSS 40 is a specific terminal (hereinafter, LTE only device) capable of only LTE service for the corresponding subscriber terminal 30 during location registration. It is possible to provide information on whether or not it is the OTA server 20 to the OTA server 20 .

2 is a configuration diagram of a server for network-based remote terminal management according to an embodiment of the present invention. As an example, it is a detailed configuration diagram applied to the OTA server 20 of FIG. 1 , and as shown in the diagram, terminal confirmation It may include a unit 21 , a server connection request unit 23 , a download unit 25 , a storage unit 27 , and a recognition unit 29 .

The terminal check unit 21, for example, when a ULR (User Location Request) message as a registration request message is received from the MME 11 according to an attempt to access the LTE network 10 from the subscriber terminal 30, the received URL message It is checked whether the terminal information (eg, IMSI, IMEI, etc.) in the terminal information is the terminal information before opening, and if it is terminal information before opening, whether the corresponding subscriber terminal 30 is a specific terminal capable of only LTE service, that is, an LTE only device. or not, and as another example, for the subscriber terminal 30 that has been connected to the LTE network 10, the terminal data change from the IT, operator, service provider, etc. When a terminal management request message is received, it can communicate with the HSS 40 to check whether the corresponding subscriber terminal 30 is an LTE only device.

When the corresponding subscriber terminal 30 is identified as an LTE only device through the terminal confirmation unit, the server access request unit 23 is configured to perform profile provisioning, remote application management of the terminal, and remote control of the terminal. To transmit a server access request message for remote device management including at least one of remote file management to the corresponding subscriber terminal 30 through the MME 11, the server access request message may include a Downlink NAS Transport message.

The download unit 25 sends a remote terminal to the connected subscriber terminal (or UICC) 30 when the corresponding subscriber terminal 30 is connected on the basis of the server access request message transmitted through the server connection requester 23 . For downloading data for management (device management), data for remote device management includes opening profile provisioning data, remote application management data of the terminal, and remote of the terminal It may be at least one of remote file management data, and the download message may include a Hyper Text Transfer Protocol (HTTP) type message.

The storage unit 27 is for storing the first terminal number information to be used before the opening and the second terminal number information to be used after the opening allocated for the new subscriber, for example, provisioned from the business computer server 60 and stored therein. The number information may include pseudo-IMSI information as information about a phone number of a subscriber terminal to be used temporarily before opening, and the second terminal number information is information on a phone number of a subscriber terminal to be used after opening, and is information about an international mobile phone number (IMSI). Subscriber Identity) information may be included.

The recognition unit 29 determines whether 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 . This is to recognize whether or not the opening is necessary.

As another example, the recognition unit 29 may be included in the HSS 40 . In this case, when the HSS 40 recognizes the need for opening, the OTA server 20 transmits an opening request message to the OTA server 20 . It can be made to recognize whether an opening is necessary.

3 is a flowchart of a method for network-based remote terminal management according to an embodiment of the present invention, a flowchart for LTE network-based remote opening profile provisioning, and is applied to the apparatus of FIGS. 1 to 2 It will be described in parallel with the operation of the device.

When an application for opening a new USIM with a phone number requested by a customer is requested by new subscription to a telecommunication company or replacement of USIM, the sales computer server (IT) uses the same network (NW) remote SIM opening system as the OTA (20). Subscriber information is provisioned (S301), and accordingly, the OTA 20 provides subscriber information including an IMSI Profile before opening (eg, first terminal number information) and a phone number Profile to be used after opening (eg, second terminal number information). to store (S302).

After mounting the USIM (or referred to as UICC) in the terminal 30 before opening, when the power is turned on, the terminal (UICC / UE) 30 attaches to the LTE network 10 with at least the first terminal number information before opening (Attach) is attempted (S303), and the MME 11 registers SMS in MME-related information (SMS-Register-Request, MME-Number-for-MT-SMS, etc.) and first terminal information (IMEI) A ULR message as a request message is transmitted to the OTA 20 (S304). Here, the OTA 20 may perform the role of the HSS.

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

After the LTE network acquisition is successful, the OTA 20 performs IMSI information (Pseudo-IMSI range check) that defines in advance whether the corresponding subscriber is a subscriber in need of opening based on the terminal number information (IMSI) included in the ULR message of step S304. (1st terminal number information) is judged according to whether or not the subscriber is in need of opening, device capability is checked with the IMEI information received from the MME 11, and if the corresponding subscriber terminal 30 is an LTE-only device, it is opened Transmits a TFR (MT Forward Short Message Request) message for progress to the MME 11 (S307), and receives a TFA (MT Forward Short Message Answer) message in response to the TFR message from the MME 11 (S308) .

In the present embodiment, since the OTA 20 can perform the role of the HSS (providing the S6a Interface function), the TFR to the MME 11 in step S307 without sending the S6c message to the HSS (Send Routing Info for SMS Procedure). message can be sent.

Next, the MME 11 transmits OTA access request information for opening to the subscriber terminal 30 by loading it in a Downlink NAS Transport message (S309). In this embodiment, the NAS message of step S309 is used as a trigger for HTTP access, but is not limited thereto. When the size of the opening data is small, the NAS message of step S309 can be transmitted by loading the opening data. .

When the NAS message is used as a trigger in step S309, the OTA 20 transmits the data including the subscriber terminal (or UICC) 30 and a predefined service identification ID to classify the data to be downloaded.

Next, the subscriber terminal (USIM) 30 attempts an HTTP connection request to the OTA 20 based on the NAS message received from the OTA 20 through the MME 11, and at this time, in step S309 to the OTA 20 The received service identification ID is included in the HTTP message and transmitted (S310).

As in step S310, returning the service identification ID in the terminal trigger message to the OTA without changing the terminal (USIM) may facilitate service scalability.

The OTA 20 determines whether it is an opening data download request based on the service classification 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 station (USIM) 30 completes the opening with the new number (S312), it attempts to access the network with the changed number (S313).

4 is a flowchart of a method for network-based remote terminal management according to another embodiment of the present invention, and is a flowchart for LTE network-based remote terminal management (device management). It will be described in parallel with the operation of the device.

In the state where the subscriber terminal (UICC / UE) 30 is successfully connected to the LTE network and registered in the HSS 40 (S401), the OTA 20 is an external business computer server (IT), network operator (Network Operator) , or when a terminal management request message for data change of the subscriber terminal 30 is received from the service provider (S402), the subscriber terminal communicates with the HSS 40 through an SPR/SPA message (S403) (30) It is checked whether this is a specific terminal capable of only LTE service (S404).

For example, in step S402, when the network operator needs to change device data (eg, PLMN) for network operation or service provision, or when the service provider needs to change device data, provision device data to the OTA 20 ( device data provisioning) can be requested. Device data change in this embodiment may include Remote File Management, Remote Applet Management, and the like.

In addition, in step S403, the OTA 20 transmits/responses an SPR/SPA message with the HSS 40 to transmit a NAS message for device data provisioning, in which case the HSS 40 is an LTE-only device. The information may be transmitted to the OTA 20 in an SPA message.

Next, when it is confirmed in step S404 that the subscriber station 30 is an LTE only device, the OTA 20 sends a server access request message for remote device management to the corresponding subscriber station 30 through the MME 11 . It is transmitted to (S405~S407).

For example, the OTA 20 transmits a TFR (MT Forward Short Message Request) message to the MME 40 (S405), and the MME 40 sends a TFA (MT Forward Short Message Answer) message to the OTA 20. After sending and responding to the TFR message (S406), a Downlink NAS Transport message is transmitted to the subscriber terminal 30 (S407).

When the NAS message is used for the trigger purpose in step S407, the OTA 20 transmits the terminal (USIM) 30 or the application and the predefined service identification ID in the TFR message and the NAS message, and , the service classification ID is for classifying data that the OTA 20 needs to download to the subscriber terminal 30 .

The process of steps S405 to S407 described above describes an example of using a NAS message as a trigger for HTTP connection because the size of device data is large as in the case of a specific applet delete of UICC. When the size of the device data is small, the device data can be directly loaded and transmitted in the TFR message and the NAS message in steps S405 to S407.

Subsequently, the subscriber terminal (USIM) 30 attempts an HTTP (Hyper Text Transfer Protocol) connection request to the OTA 20 while processing the NAS message received from the OTA 20 through the MME 11 , in this case In the above process, the service identification ID received from the OTA 20 is included in the HTTP (Hyper Text Transfer Protocol) message and transmitted (S408). It is easy to extend the service by returning OTA without changing the service identification ID in the terminal trigger message in the terminal (USIM).

Finally, the OTA 20 downloads device data (ie, 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 network-based remote terminal management according to an embodiment of the present invention may be implemented as a computer-readable recording medium including program instructions for performing various computer-implemented operations. The computer-readable recording medium may include program instructions, local data files, local data structures, etc. alone or in combination.
