More specifically, the present disclosure relates to an electronic device for providing a method for executing a service or application associated with an IoT device and a method for operating the electronic device. Background Art

[0002] The Internet has evolved from a human-centered connection network through which humans generate and consume information to an Internet of Things (IoT) network that exchanges and processes information between distributed elements such as objects. Internet of Everything (IoE) technology, which combines big data processing technology and IoT technology via connections with cloud servers, etc., has also emerged. In order to realize IoT, technical factors such as sensing technology, wired / wireless communication, network infrastructure, service interface technology and security technology are required, and research on technologies such as sensor networks, machine-to-machine (M2M) communication, machine type communication (MTC), etc. for connection between objects has been conducted recently. In the IoT environment, by collecting and analyzing data generated from connected objects, intelligent Internet technology (Internet technology, IT) services for creating new value for people's lives can be provided. IoT can be applied to various fields such as smart homes, smart buildings, smart cities, smart cars or connected cars, smart grids, health care, smart home appliances or high-tech medical services via the integration and combination of existing information technology (information technology, IT) and various industries.

[0003] With the development of wireless communication systems, various services can be provided, and a method for effectively providing these services is required. For example, in medium access control (MAC), a ranging technology for measuring the distance between electronic devices by using ultra-wideband (UWB) can be used. UWB is a wireless communication technology that uses an ultra-wideband of several GHz or more in a baseband without using a radio carrier.

[0063] Figure 2 is a diagram illustrating a communication process of a plurality of electronic devices according to an embodiment of the present disclosure.

[0064] refer to Figure 2, the first electronic device 210 and the second electronic device 220 may perform communication with each other through a device discovery process 203 , a link establishment process 204 , and a data communication process 205 .

[0065] In the device discovery process 203, each of the first electronic device 210 and the second electronic device 220 may search for other electronic devices capable of performing device-to-device (D2D) communication in nearby electronic devices. Thus, each of the first electronic device 210 and the second electronic device 220 may determine whether to establish a link for D2D communication. For example, the first electronic device 210 and the second electronic device 220 may send a search signal for searching for other electronic devices, and discover the other device in response to receiving a response signal sent from an electronic device that has received the search signal. In addition, the first electronic device 210 may receive a response signal sent by the second electronic device 220, and thus confirm that the second electronic device 220 capable of performing D2D communication is within the D2D communication range.

[0066] In the link establishment process 204, each of the first electronic device 210 and the second electronic device 220 may establish a link for data transmission with an electronic device to which data is to be sent among the electronic devices discovered in the device discovery process 203. For example, the first electronic device 210 may establish a link for data transmission with the second electronic device 220 discovered in the device discovery process 203. The wireless connection process of the first electronic device 210 and the second electronic device 220 through the device discovery process 203 and the link establishment process 204 may be referred to as pairing.

[0067] In the data communication process 205, each of the first electronic device 210 and the second electronic device 220 may send data to and receive data from the device for which a link is established in the link establishment process 204. For example, the first electronic device 210 may send data to and receive data from the second electronic device 220 through the link established in the link establishment process 204.

[0068] According to an embodiment of the present disclosure, in the data communication process 205, the second electronic device 220 may send information about the second electronic device 220 to the first electronic device 210, and the information about the second electronic device 220 includes identification information of the second electronic device 220, information about the communication protocol available in the second electronic device 220, and information about the wireless communication method available in the second electronic device 220. The identification information of the second electronic device 220 may be unique identifier (ID) information of the second electronic device 220 to distinguish it from other electronic devices. The communication protocol refers to a system of formats and rules for exchanging messages between the second electronic device 220 and an external electronic device. Examples of the communication protocol include Hypertext Transfer Protocol (HTTP), Secure Hypertext Transfer Protocol (HTTPS), File Transfer Protocol (FTP), Secure File Transfer Protocol (SFTP), Telnet (Terminal Network), Post Office Protocol Version 3 (POP3), Simple Mail Transfer Protocol (SMTP), Secure Shell (SSH), Secure Sockets Layer (SSL), Simple Object Access Protocol (SOAP), and Address Resolution Protocol (ARP), but are not limited thereto. Examples of wireless communication methods include Wi-Fi, Bluetooth, BLE, WFD, UWB, NFC, Zigbee, etc., but are not limited to these.

[0069] In the UWB ranging process 206, UWB ranging may be performed to measure the distance and direction between the first electronic device 210 and the second electronic device 220. For example, in a case where the first electronic device 210 is a smart phone storing a digital key of a vehicle and the second electronic device 220 is a vehicle, the distance between the smart phone and the vehicle may be measured by using a plurality of UWB communication modules installed in the smart phone and the vehicle, and then based on the measurement result, when the vehicle and the smart phone are close to each other within a certain distance or less, the door may be automatically opened, thereby improving the convenience of the user. The vehicle and the smart phone may perform multicast ranging or broadcast ranging. According to an embodiment of the present disclosure, the UWB ranging process 206 may be omitted.

[0070] The electronic device according to an embodiment of the present disclosure may perform ranging by using a ranging frame (RFRAME) and a ranging control frame. Two types of devices related to ranging control may be referred to as "controllers" or "controlled devices".

[0071] First, a controller may be defined as a device that defines and controls ranging parameters by sending a ranging control frame together with a ranging control information element (IE). The ranging control frame is used to set the ranging parameters to be used for ranging. The term "ranging control frame" may be referred to as a "ranging control message".

[0072] A controlled device may be defined as a device that uses ranging parameters received from a controller. At least one controlled device may be managed by a controller. The method of determining the role of a device (eg, as a controller or a controlled device) and selecting ranging parameters may be implemented in various ways.

[0073] Additionally, the two types of devices used for ranging control may be referred to as “initiators” or “responders.” An initiator is a device that starts ranging by sending a poll. A responder is a device that responds to a poll received from an initiator.

[0074] The controller can determine the devices and their types participating in ranging by using the ranging initiator / responder list (IRL) IE or the ranging schedule (RS) IE. The IRL IE and RS IE can be carried by the ranging control frame. For scheduling-based ranging, the RS IE can be configured by the controller to manage resources and indicate the role of the device (i.e., the role of the initiator or responder). The IRL IE can be used in contention-based ranging to determine the role of the device when the RS IE is not used.

[0075] The scheduling mode field of the ranging control IE indicates whether the ranging frame is sent by using contention or by using scheduling. Devices not specified by these IEs cannot participate in ranging. When a polling frame needs to be sent by a device, the device type of the device can be determined as an initiator, and the device that responds to the polling frame can be determined as a responder.

[0076] In contention-based multicast / broadcast ranging, when the controller is the only initiator in ranging and the destination address field in the medium access control (MAC) header of the ranging control frame specifies a responder, the controller may not add the IRL IE to the ranging control frame.

[0077] Because the ranging control frame includes the IRL IE or RS IE, the controller may receive the ranging control frame to identify whether to send a poll. In the case where the device type of the controller is specified as an initiator in the IRL IE or RS IE, the controller may send a polling frame. Each of the controller and the controlled device may serve as an initiator or a responder. Any one of the first electronic device 210 and the second electronic device 220 may serve as a controller, and the other may serve as a controlled device.

[0078] In the application execution process 207, the first electronic device 210 may determine an application executable by the second electronic device 220 based on information about the second electronic device 220 received from the second electronic device 220 (e.g., identification information of the second electronic device 220, information about a communication protocol available in the second electronic device 220, and information about a wireless communication method available in the second electronic device 220). A list of applications executable by the second electronic device 220 may be provided to the user through the display of the first electronic device 210, and the user may select an application to be executed by the second electronic device 220. Information about the application selected by the user may be transmitted from the first electronic device 210 to the second electronic device 220, and the second electronic device 220, which has received the information about the application, may execute the application independently or by interacting with the first electronic device 210.

[0079] In the application execution response process 208, the second electronic device 220 may transmit a response message including information on whether the application information transmitted from the first electronic device 210 is received, or information on a result of executing the application according to the transmitted application information.

[0080] Figure 3 An example of single-sided two-way ranging (SS-TWR) using a ranging control frame according to an embodiment of the present disclosure is shown.

[0081] refer to Figure 3 , when the controller 100 is set to send a polling frame, such as Figure 3 As shown in the flowchart 301 of FIG. 1 , the controller 100 may act as an initiator and send a polling frame. On the other hand, in the case where the controller 100 sets the controlled device 200 to send a polling frame, as shown in FIG. Figure 3 As shown in the flowchart 302 of FIG. 1 , the slave 200 may act as an initiator and send a polling frame.

[0082] In addition, the ranging control frame may include a ranging confirmation IE indicating a ranging response type. A plurality of slaves may be used for multicast / broadcast / many-to-many (M2M) ranging.

[0083] The device according to an embodiment of the present disclosure may perform ranging in units of ranging blocks.

[0084] A ranging block is a time period used for ranging. A ranging block includes a plurality of ranging rounds. A ranging round is a time period required to complete a distance measurement cycle between a pair of ranging devices participating in a ranging exchange. A ranging round includes a plurality of ranging slots. A ranging slot is a time period used to send a ranging frame.
