Description

Integrated terminal device and control method of integrated terminal device {INTEGRATED TERMINAL DEVICE AND CONTROL METHOD THEREOF}

The present invention relates to a terminal device and a control method for integrating and utilizing an Access Point (AP) and a Set-Top Box AI speaker.

Recently, with the use of broadcasting services such as cable TV and IPTV (Internet Protocol TV), the demand for APs (Access Points) and set-top boxes installed within the home has increased. AP is a device that connects to the wireless Internet and transmits and receives Wi-Fi signals. Users can receive Internet services for various devices, including smartphones and PCs, through the AP's Wi-Fi connection. In addition, users can use a set-top box connected to a TV to watch terrestrial broadcasts and IPTV, and install and use an AI speaker that recognizes the user's commands through voice recognition and processes the commands or provides related information. .

Despite the high demand for APs, set-top boxes, and AI speakers, each device is often comprised of a separate terminal. In this case, despite the miniaturization of devices, there is a problem that space utilization in the home is reduced because a separate space is needed for each device. In addition, since power must be supplied separately to each device, multiple power cables are required, which spoils the interior or aesthetics of the home, and there is a problem in that power consumption increases due to the power consumption of each device. In addition, each user must purchase each device separately in order to use each device's services, which increases the cost required to build the related system.

In response to this demand, attempts have been made to integrate the above-mentioned devices into one terminal, but there is a problem in that the efficiency of the method of operating with each other and the format of input and output data is reduced.

In addition, in order to use an integrated device by subscribing to a telecommunication company, an activation process and a firmware upgrade process during use are required. However, in the past, the method of opening or upgrading such an integrated device is not defined, so there is a problem of low usability.

Figure 1 is a configuration diagram of an integrated terminal device 10 according to an embodiment of the present invention.

Referring to FIG. 1, the integrated terminal device 10 may include an AP unit 100, an STB unit 200, and an AI speaker unit 300.

AP stands for Access Point and is a device connected to the Internet through wireless LAN (Wi-Fi). In general, devices that use wireless LAN (laptops, smartphones, tablets, etc.) can access the Internet by connecting to an AP. AP can act as a bridge between wired Internet and wireless LAN.

And, a set-top box is a digital device that connects various media such as TV and the Internet. A set-top box is a device that allows you to watch or record Internet broadcasts on a TV, or watch various content connected to the Internet. It mainly has the function of decoding and watching TV signals, as well as a digital video recorder (DVR) and network media player. It provides various functions such as:

Additionally, an AI speaker is a speaker equipped with artificial intelligence technology and is a device that can interact with the user using voice recognition technology and natural language processing technology. AI speakers provide a variety of functions, including playing music, providing weather information, and controlling smart home devices, and can be operated through voice commands.

When integrating each of the above devices, especially when integrating APs, set-top boxes, and AI speakers, each device must not lose its unique functionality. In addition, when integrating an AP and a set-top box, the set-top box for IPTV and terrestrial broadcasting must be able to use the AP's Internet line, and a linkage method between the AP and the set-top box must be established in order for the set-top box to control the AP.

For example, if a user cannot watch IPTV and wants to check the Internet connection, the user can check the Internet connection status through the AP and change the AP's settings. In this case, the terminal device that integrates the AP and the set-top box must be able to link the IPTV and the AP, and in this process, it must be configured to read the status value of the AP from the IPTV set-top TV and change the existing AP settings.

Additionally, if a user tries to upgrade the firmware of the set-top box, the Internet connection may be terminated while performing the firmware upgrade operation, which may cause the upgrade information to not be properly reflected and cause problems in the operation of the device. Therefore, a terminal device that integrates an AP and a set-top box must be able to control the AP's Internet connection from being terminated or the AP from being rebooted to provide stability when upgrading the set-top box.

In addition, when a user wants to change the AP's settings through an AI speaker, a configuration is required so that the AI speaker reads the status of the AP and informs the user of it so that the user can set it.

The integrated terminal device 10 according to an embodiment of the present invention may appear packaged as a single terminal device from the outside, but may include components that perform the functions of the AP, set-top box, and AI speaker internally. there is. That is, the integrated terminal device 10 can integrate an AP, a set-top box, and an AI speaker into one terminal device.

The performing part will be defined as the AI speaker unit 300.

Referring to FIG. 1, the AP unit 100 may include a WiFi CPU 110. The WiFi CPU (110) is a central processing unit that processes data input for the operation of the AP unit (100) and, depending on the setting or function, receives a wireless signal with a bandwidth of 2.4GHz WiFi (120) or 5GHz WiFi (130). can be provided. Additionally, the WiFi CPU 110 can be connected to a storage device such as flash memory or RAM 140 to input and output data, and can be connected to the power source 150 of the integrated terminal device 100. The WiFi CPU (110) can be connected to WAN, LAN1, LAN2, and LAN3 (160), which are ports for wired data input and output, and can be connected to other devices or devices via wireless LAN through WPS (WiFi Protected Setup) (170) input. there is. Additionally, the WiFi CPU 110 can display whether data is input or output through the LED 180.

The STB unit 200 may include an STB CPU 210. The STB CPU 210 is a central processing unit that processes data input for the operation of the STB unit 200, and can provide a wireless Bluetooth 220 connection or an infrared connection 230 function depending on settings or functions. Additionally, the STB CPU 210 can be connected to a storage device such as flash memory or RAM 240 to input and output data, and can be connected to an external device through the USB 250 port. Additionally, the STB CPU 210 may be connected to the power source 260 of the integrated terminal device 100. In addition, the STB CPU (210) supports ?銹８? for display on the TV through ports (270) such as DC-JACK, S/PDIF, and HDMI. It can be transmitted, and the power can be turned on or off through the On/Off switch 280. At this time, the On/Off switch 280 is formed on the outer surface of the integrated terminal device 100 so that the user can easily control the power to the STB unit 200.

The AI speaker unit 300 may include an AI CPU (310). The AI CPU 310 may correspond to a central processing unit that processes data input for the operation of the AI speaker unit 300. The AI speaker unit 300 can recognize and analyze voice signals input through the microphone 320 and transform them into appropriate text messages, and process preset commands based on these text messages. The AI CPU 310 can transform the processed results or externally input data into a sound signal and output it through the speaker 330. In another embodiment of the present invention, the function of the AI speaker unit 300 may be included in the function of the STB unit 200. That is, a microphone or speaker is connected to the STB CPU 210, and the STB CPU 210 may recognize and process the input voice, transform the processed result into a sound signal, and output it through the speaker.

In an embodiment of the present invention, the AP unit 100 and the STB unit 200 can be connected to each other for Ethernet communication, and can transmit and receive packets to each other through IPC (Inter Process Communication).

In Figure 1, it is illustrated that the AP unit 100 and the STB unit 200 are connected by Ethernet, but other internal interfaces such as SD interface and USB interface other than Ethernet can be configured, and the AP unit 100 and STB unit (200) can be connected in the form of a bus according to IEEE 802.3.

Since the AP unit 100 and the STB unit 200 of the integrated terminal device 10 are physically connected within the integrated terminal device 10 as described above, the connection relationship is not exposed to the outside and the integrated terminal device 10 ), the utilization of space within the home increases, and less damage is done to the interior or aesthetics of the home.

FIG. 2 is a diagram illustrating and illustrating a process for allocating an IP according to DHCP within an integrated terminal device according to an embodiment of the present invention.

The AP unit 100 may initiate home network communication with the STB unit 200 through DHCP (Dynamic Host Configuration Protocol) and assign an IP address to the STB unit 200.

A conventional AP is generally connected to an external Internet network, can be assigned a unique IP address for communication, and can configure Wi-Fi and wired LAN as a lower level terminal connected to the AP. A conventional set-top box is connected to a conventional AP through a wireless or wired LAN device, and as a sub-terminal of the AP, it can be connected to the Internet network through the AP.

The integrated terminal device 10 according to an embodiment of the present invention includes an AP unit 100 and an STB unit 200, and the set-top box configures Ethernet through an Ethernet GPIO interface rather than a home AP and an Ethernet cable in the integrated terminal. It can be configured in a simple form without a direct LAN line, thereby increasing internal space utilization. Through this, the set-top box can receive IPTV packets to the home AP sub-terminal.

Referring to FIG. 2, the AP unit 100 is connected to the STB unit 200 and the integrated terminal device 10 via Ethernet, and the AP unit 100 allocates an IP address to the STB unit 200. You can understand the process.

More specifically, the AP unit 100 may allow the STB unit 200 to receive network configuration information such as an IP address, subnet mask, and default gateway through DHCP (Dynamic Host Configuration Protocol). When the STB unit 200 broadcasts a DHCP discover message through Opt 60 or Opt 77, the AP unit 100, which recognizes this, can transmit a DHCP offer message to the STB unit 200. The STB unit 200 may transmit a DHCP request message to the AP unit 100 through Opt 60 or Opt 77. Afterwards, when the AP unit 100 responds with a DHCP Ack message, a home network is formed between the AP unit 100 and the STB unit 200, and protocols such as IGMP (Internet Group Management Protocol) or RTP (Real-time Transport Protocol) are used. Multimedia streaming becomes possible.

In the embodiment of FIG. 2, the IP allocation method of the AP unit 100 may vary depending on the preset IP allocation method of the AP unit 100. For example, a router mode in which the AP unit 100 allocates different internal IP addresses to lower level terminals of the AP unit 100 and each terminal has one public IP address to the outside, or the AP unit (100) The IP allocation method may vary depending on the bridge mode, which uses ) as a switching hub to have a separate public IP for each device.

FIG. 3 is a diagram illustrating by way of example that the AP unit 100 and the STB unit 200 in the integrated terminal device 10 according to an embodiment of the present invention are interconnected through IPC.

The WiFi CPU 110 of the AP unit 100 and the STB CPU 210 of the STB unit 200 may be connected within the integrated terminal device 10 through IPC (Inter Process Communication). Internal interworking between two CPUs through this connection can be materialized by performing data transmission through an arbitrary port. For example, the WiFi CPU 110 of the AP unit 100 and the STB CPU 210 of the STB unit 200 are connected to each other through port 7654 and can transmit and receive data to each other.

In the example of FIG. 3, it can be seen that the AP unit is assigned an IP address of 10.0.0.2, and the STB unit 200 is assigned an IP address of 10.0.0.8. In the example of FIG. 3, when the Internet network connection method of the AP unit 100 is set to bridge mode, the AP unit 100 may assign a public IP to the lower terminal. In an embodiment of the present invention, the STB unit ( 200) may be configured as a lower terminal of the AP unit 100.

When the AP unit 100 and the STB unit 200 are internally interconnected through IPC, it is possible to prevent ARP Requests from being transmitted to an external public network for 10.0.0.8, which is the IP address of the STB unit 200. If the STB unit 200 transmits an ARP Request to the outside, a response to the ARP Request is received from the AP unit 100, which is unnecessary for the STB unit 200 consisting of the AP unit 100 and its subordinate terminals. Because it is a movement.

The AP unit 100 or the STB unit 200 is configured to allow different devices to transmit and operate status and commands through IPC. For this, the AP unit 100 and the STB unit 200 are connected to the socket of the connection interface. This can always remain open.

Figure 4 is a diagram for illustrating and illustrating a process in which the AP unit and the STB unit in the integrated terminal device transmit and decrypt encrypted data according to an embodiment of the present invention.

Figure 4 illustrates a process of transmitting a request packet generated by the STB unit 200 to the AP unit 100 and transmitting a response packet corresponding to the request packet to the AP unit 100. As will be described later, the data portion of the packet transmitted between the AP unit 100 and the STB unit 200 may be in JSON (JavaScript Object Notation) format. Additionally, the header portion of the request packet of the STB unit 200 may include token information (Channel-Auth-Token) for data encryption. Here, the token information is randomly generated and can have a size of 16 bytes * n.

More specifically, the packet encryption process in FIG. 2 involves the STB unit 200 generating token information in the header part and receiving a separately delivered symmetric key, combining the token information and the symmetric key to perform encryption according to AES-128. It may include encoding and transmitting.

Here, the symmetric key can be set to a size of 16 bytes * n, and if the size is smaller than this, it can be padded with 0x00 to meet the standard of 16 bytes. AES-128 is one of the encryption technologies called Advanced Encryption Standard (AES). It is one of the commonly used symmetric key encryption algorithms and may correspond to the encryption technology adopted in 2001 by the U.S. National Institute of Standards and Technology (NIST). there is. AES 128 encrypts data using a 128-bit long symmetric key, and the secret key is used for both encryption and decryption. AES 128 has features such as secure key generation and management, high security level, and fast processing speed.

In FIG. 4, the decryption process may be performed by decrypting the packet received by the AP unit 100 by combining token information and a symmetric key. Afterwards, the encryption and decryption processes performed when the AP unit 100 generates a response packet in response to the request packet from the STB unit 200 and transmits the response packet may be the same as the above-mentioned process.

In Figure 4, AES-128 is used for data encryption/decryption, but for stronger security, AES-192 or AES-256 may be used, or other encryption/decryption technology may be used.

Figures 5 to 7 are diagrams for illustrating and illustrating a process in which the STB unit performs opening according to an embodiment of the present invention.

Referring to FIG. 5, the AP unit 100 may play a role of delivering a message to be transmitted by the STB unit 200 to the management server 20 during the opening process of the STB unit 200. More specifically, the AP unit 100 can deliver the message provided from the STB unit 200 to the management server 20 through NAT (Network Address Translation) processing, and similarly transmit the message provided from the management server 20. It can be transmitted to the STB unit 200. Here, the management server 20 may refer to a management server for terminals using TR-069. At this time, the AP unit and the STB unit may be linked to the management server through a preset linked URL (for example, “https://box.xxcems.com/device/tr-069”).

In FIG. 5 , when the STB unit 200 transmits self-opening target confirmation information to the AP unit 100, the AP unit 100 may transmit the information to the management server 20. Thereafter, the management server 20 generates self-opening target response information and provides the information to the AP unit 100, and the AP unit 100 sends the self-opening target response information received from the management server 20 to the STB. It can be provided to unit 200.

Referring to FIG. 6, the self-opening process of the STB unit 200 can be seen in more detail through an example. Here, self-opening may refer to a process in which the user performs the opening work on his own without visiting the Internet service provider of the STB unit 200 or a professional technician from a telecommunication company.

In Figure 6, the self-opening process of the STB unit 200 includes a self-opening target confirmation step (S510), a self-opening attempt step (S520), an authentication step (S530), an opening step (S540), and a boot step (S550). You can.

In the self-opening target confirmation step (S510), the STB unit 200 transmits self-opening target confirmation request information to the management server 20 through the AP unit 100, and the STB unit 200 is included in the self-opening target. If so, this may be a process in which the management server 20 generates self-opening target response information and transmits it to the STB unit 200 through the AP unit 100.

In the self-opening attempt step (S520), the STB unit 200 transmits SMS authentication request information to the management server 20 through the AP unit 100 and manages SMS authentication response information including an authentication number for SMS authentication. This may be a process in which the server 20 transmits to the STB unit 200 through the AP unit 100.

In the authentication step (S530), the STB unit 200 transmits self-opening request information including an authentication number to the management server 20 through the AP unit 100, and if the entered authentication number is correct, the management server 20 Authentication success information to allow opening is transmitted to the STB unit 200 through the AP unit 100, or if the authentication number is incorrect, the management server 20 sends authentication failure information to the AP unit 100 to disallow opening. This may be a process of transmitting to the STB unit 200 through .

In the opening step (S540), the STB unit 200 transmits opening request information to the management server 20 through the AP unit 100, and the management server 20 transmits opening response information to the STB via the AP unit 100. This may be a process of transmitting to unit 200.

In the boot step (S550), the STB unit 200 transmits authentication request information to the authentication server 30 through the AP unit 100, and the authentication server 30 transmits information about the authentication result to the AP unit 100. This may be a process of transmitting to the STB unit 200. In addition, in the boot step (S550), the STB unit 200 transmits boot or bootstrap information to the management server 20 through the AP unit 100 and confirms the boot or bootstrap information. And it may include the step of the management server 20 transmitting information about the authentication result to the STB unit 200 through the AP unit 100.

Referring to FIG. 7, the HTTPS triggering opening process of the STB unit 200 can be seen in more detail through an example. Here, HTTPS triggering opening may mean a process in which the Internet service provider or telecommunication company of the STB unit 200 directly accesses the STB unit 200 and opens the service.

In Figure 7, the HTTPS triggering opening process is such that the management server 20 transmits HTTPS opening triggering request information to the STB unit 200 through the AP unit 100, and the STB unit 20 transmits HTTPS opening triggering response information to the AP unit. It may include a process of transmitting to the management server 20 through (100). In addition, in the HTTPS triggering opening process, the STB unit 200 transmits opening request information to the management server 20 through the AP unit 100, and the opening response information management server 20 transmits the opening request information to the AP unit. It may include a process of transmitting to the STB unit 200 through 100.

A message transmitted from the AP unit 100 or the STB unit to the management server 20 during the self-opening process of FIG. 6 or the HTTPS triggering opening process of FIG. 7 may include Product Class and MAC address. In order to inform the management server 20 that the STB unit 200 is a subordinate terminal of the AP unit 100, the STB unit 200 may transmit the MAC address including the MAC address of the AP unit 100. And when the management server 20 attempts to perform terminal control on the AP unit 100 and the STB unit 200 by a method such as UDP Hole Punching, the management server 20 provides the terminal management service types ProductClass and SubProductClass. It can be operated separately. Through this distinction, the integrated terminal device 10 can recognize the AP unit 100 based on ProductClass and the STB unit 200 based on SubProductClass. And, through this distinction, the management server 20 can control the AP unit 100 and the STB unit 200 by viewing them as one integrated terminal device.

Figures 8 and 9 are diagrams for illustrating and illustrating a process in which the STB unit performs a firmware upgrade according to an embodiment of the present invention.

Referring to FIG. 8, the firmware upgrade process of the STB unit 200 is a step in which the STB unit 200 transmits software upgrade request information to the AP unit 100 (S810), and the AP unit 100 sends a software upgrade request. If the STB unit 200 is determined to be in a suitable state for firmware upgrade in response to the information, the upgrade response information is transmitted to the AP unit 100 (S820), and the STB unit 200 is sent to the upgrade server 40. In the step of transmitting software upgrade request information (S830), when the upgrade server 40 determines that software for upgrade can be downloaded to the STB unit 200 in response to the software upgrade request information, it transmits software upgrade response information. Step (S840), the STB unit 200 transmitting software download request information to the upgrade server 40 (S850), and the upgrade server 40 transmitting download response information to the STB unit 200. may include.

On the other hand, in the firmware upgrade process of the AP unit 100, the AP unit 100 can directly communicate with the upgrade server 40 to download the software required for the upgrade.

In this way, in order to upgrade the STB unit 200, sending upgrade request information to the AP unit 100 and receiving upgrade response information ensures that the STB unit 200 is a subordinate device of the AP unit 100 and connects to the Internet. This is to enable the upgrade server 40 or the management server 30 to manage the AP unit 100 and the STB unit 200 in conjunction with each other.

The firmware upgrade process of the STB unit 200 can be completed by performing the steps in FIG. 8 followed by the steps in FIG. 9.

More specifically, referring to FIG. 9, the firmware upgrade process of the STB unit 200 involves sending software deletion result information to the STB unit 200 to notify the upgrade server 41 that the software of the previous version of the upgrade has been deleted.
