1. Field of the Disclosure


The present disclosure relates generally to a method and an apparatus for activating a scan function of an electronic device, and more particularly, to a method and an apparatus for determining an activation period of a scan function in an electronic device.


2. Description of the Related Art


According to a development of an Internet Protocol version 6 (IPv6), a unique IP may be allocated to an object. After a unique IP is allocated to an object, the object may access an Internet network, and transmit and receive data. Accordingly, an Internet of objects (e.g., an Internet of Things (IoT)) is possible, and research on smart home systems for effectively utilizing an automatic device has been actively pursued. A smart home system refers to a system in which a plurality of devices is registered to one electronic device to effectively and intuitively control the plurality of registered devices.


However, since the types of devices for the Internet of objects vary and have been generalized, power consumption is an issue in managing a plurality of devices in one electronic device. For example, when one electronic device periodically scans a plurality of devices for an Internet of objects, power consumption of the electronic device increases according to the type of device and the scan period.


Therefore, there is a need for a method of effectively managing a plurality of registered devices in an electronic device.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT DISCLOSURE

Hereinafter, various embodiments of the present disclosure are described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In the description below of the accompanying drawings, similar reference numerals may be used to designate similar elements.


As used herein, the expressions “have,” “may have,” “include,” or “may include,” refer to the existence of a corresponding feature (e.g., a numeral, a function, an operation, or a constituent element such as a component), and do not exclude one or more additional features.


As used herein, the expressions “A or B,” “at least one of A and/or B,” or “one or more of A and/or B” may include any or all possible combinations of items enumerated together. For example, the expressions “A or B,” “at least one of A and B” or “at least one of A or B” may include (1) at least one A, (2) at least one B, or (3) both at least one A and at least one B.


The expression “a first,” “a second,” “the first,” or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. The above expressions are used merely for the purpose of distinguishing an element from another element. For example, a first user device and a second user device may indicate different user devices regardless of the sequence or importance thereof. For example, a first element could be referred to as a second element, and similarly, a second element could be referred to as a first element without departing from the scope and spirit of the present disclosure.


When it is indicated that an element (e.g., a first element) is “(operatively or communicatively) coupled with/to or connected to” another element (e.g., a second element), it should be construed that the element is directly connected to the other element or the element is indirectly connected to the other element via yet another element (e.g., a third element). Conversely, when it is indicated that an element (e.g., a first element) is “directly coupled” or “directly connected” to another element (e.g., a second element), it may be construed that no other element exists between the element and the other element.


The expression “configured to” used in the present disclosure may be replaced with, for example, “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may indicate that the device, together with other devices or components, “is able to.” For example, the phrase “processor adapted (or configured) to perform A, B, and C” may refer to a dedicated processor (e.g. an embedded processor) only for performing the corresponding operations or a general purpose processor (e.g., a Central Processing Unit (CPU) or Application Processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.


The terms used in the present disclosure are only used to describe certain embodiments of the present disclosure, and are not intended to limit the present disclosure. A singular expression may include a plural expression, unless the context clearly indicates otherwise. Unless clearly defined otherwise, all terms used herein, including technical terms and scientific terms, may have the same meanings as commonly understood by a person of ordinary skill in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary are to be interpreted to have the meanings equal to the contextual meanings in the relevant field of the art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even a term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.


For example, an electronic device may include at least one of a smartphone, a tablet Personal Computer (PC), a mobile phone, a video phone, an electronic book (e-book) reader, a desktop PC, a laptop PC, a netbook computer, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a Moving Picture Experts Group Audio Layer 3 (MP3) player, a mobile medical appliance, a camera, and a wearable device (e.g., a Head-Mounted-Device (HMD) such as electronic glasses, electronic clothes, an electronic bracelet, an electronic necklace, an electronic appcessory, electronic tattoos, or a smart watch).


According to some embodiments of the present disclosure, the electronic device may be a smart home appliance. The smart home appliance may include at least one of, for example, a television, a Digital Video Disk (DVD) player, an audio player, a refrigerator, an air conditioner, a vacuum cleaner, an oven, a microwave oven, a washing machine, an air cleaner, a set-top box, a home automation control panel, a security control panel, a TV box (e.g., Samsung HomeSync™, Apple TV™, or Google TV™), a game console (e.g., Xbox™ and PlayStation™), an electronic dictionary, an electronic key, a camcorder, and an electronic photo frame.


According to another embodiment of the present disclosure, the electronic device may include at least one of various medical devices (e.g., various portable medical measuring devices (e.g., a blood glucose monitoring device, a heart rate monitoring device, a blood pressure measuring device, a body temperature measuring device, etc.), a Magnetic Resonance Angiography (MRA) machine, a Magnetic Resonance Imaging (MRI) machine, a Computed Tomography (CT) machine, and an ultrasonic machine), a navigation device, a Global Positioning System (GPS) receiver, an Event Data Recorder (EDR), a Flight Data Recorder (FDR), a vehicle infotainment device, an electronic device for a ship (e.g., a navigation device for a ship, and a gyro-compass), avionics, security devices, an automotive head unit, a robot for home or industry, an Automatic Teller Machine (ATM), a Point of Sale (POS) device in a vending location, or a device for the Internet of Things (e.g., a light bulb, various sensors, an electric or gas meter, a sprinkler device, a fire alarm, a thermostat, a streetlamp, a toaster, sporting goods, a hot water tank, a heater, a boiler, etc.).


According to an embodiment of the present disclosure, the electronic device may include at least one of a part of furniture or a building/structure, an electronic board, an electronic signature receiving device, a projector, and various kinds of measuring instruments (e.g., a water meter, an electric meter, a gas meter, and a radio wave meter). An electronic device according to an embodiment of the present disclosure may be a combination of one or more of the aforementioned various devices. An electronic device according to an embodiment of the present disclosure may be a flexible device. Further, an electronic device according to an embodiment of the present disclosure is not limited to the aforementioned devices, and may include a subsequently developed electronic device.


Hereinafter, an electronic device according to an embodiment of the present disclosure is described with reference to the accompanying drawings. In the present disclosure, the term “user” may indicate a person using an electronic device or a device (e.g. an artificial intelligence electronic device) using an electronic device.



FIG. 1 is an illustration of a user device scanning for advertisement messages from two devices on an Internet of Things (IoT) according to an embodiment of the present disclosure.


Referring to FIG. 1, an IoT device, which is a device capable of using the Internet, may transmit an advertisement message according to a period configured in the device for transmitting an advertisement message. For example, a first IoT device broadcasts an advertisement message according to a period for transmitting an advertisement message that is configured in the first IoT device, and a second IoT device broadcasts an advertisement message according to a period for transmitting an advertisement message that is configured in the second IoT device. In this case, the advertisement message transmission period of the first IoT device may be different from the advertisement message transmission period of the second IoT device.


In addition, the user device (e.g., a smart phone) may activate a scan function according to a period of time (e.g. a scan period) configured for a user device in advance, maintain an activation state (e.g., continue to operate the user device) during the scan period when the scan function is activated (e.g. a scan function activation period) to determine whether an advertisement message is received from an IoT device during the scan period.


If a time when a user device scans for an advertisement message from an IoT device is different from a time when the IoT device transmits the advertisement message, the user device cannot receive the desired information (e.g., the advertisement message) from the IoT device. In order to receive the desired information from the IoT device, a scan function activation period of the user device may be changed from short to long. However, this would increase the power consumption of the user device.


In order to resolve such problems, in the present disclosure, a method of reducing power consumption according to scan function performance is described. In the method, the user device detects, in advance, the times when an IoT device will transmit an advertisement message, and, as shown in FIG. 1, the scan function of the user device is activated only when the IoT device transmits the advertisement message.


For convenience of description, a user device is referred to below as a first electronic device and an IoT device is referred to as a second electronic device.



FIG. 2 is a block diagram of a network environment 200 including a first electronic device 201 according to an embodiment of the present disclosure.


Referring to FIG. 2, the first electronic device 201 includes a bus 210, a scan function activating module 220, a processor 240, a memory 250, an input/output interface 260, a display 270, and a communication interface 280.


The bus 210 connects elements of the first electronic device 201 and transfers communication (e.g., a control message) among the elements of the first electronic device 201.


The scan function activating module 220 receives scan time information of the first electronic device 201 and an identification of information to be scanned by the first electronic device 201. In this case, the scan time information includes a time when the scan function of the first electronic device 201 is to be activated (e.g. a time when the first electronic device 201 starts to scan), and a period when the scan function is activated (e.g. a duration of a scan). The identification of information to be scanned by the first electronic device 201 includes a type, a kind, an item and/or a clause related to the information to be scanned, and further includes an identification of a second electronic device that is to transmit the information to be scanned.


Then, the scan function activating module 220 transmits the received scan time information of the first electronic device 201 and the identification of the information to be scanned by the first electronic device 201, where the information to be scanned is by the second electronic device 401, to a server 301 in which at least one second electronic device is registered. That is, the scan function activating module 220 transmits scan time information of the first electronic device 201 and an identification of information to be transmitted by the second electronic device 201 to the server 301 in which the second electronic device 401 is registered, in order for the server 301 to control the second electronic device 401 such that the second electronic device 401 only transmits the information to be scanned by the first electronic device 201 at a time when the scan function of the first electronic device 201 is activated to scan for the information.


Then, the scan function activating module 220 activates the scan function of the first electronic device 201 at the scan time (e.g. the start time for the scan) to receive the information transmitted by the second electronic device 401. In this case, the information transmitted by the second electronic device 401 may be an advertisement message broadcast by the second electronic device 401.


In addition, the scan function activating module 220 deactivates the scan function of the first electronic device 201 when the scan period expires.


The processor 240, for example, receives instructions from other elements (e.g., the scan function activating module 220, the memory 250, the input/output interface 260, the display 270, the communication interface 280, and the like) through the bus 210, decodes the received instructions, and executes an operation or processes data according to the decoded instructions.


The memory 250 stores instructions or data received from the processor 240 or other elements (e.g., the scan function activating module 220, the memory 250, the input/output interface 260, the display 270, the communication interface 280, and the like) or generated by the processor 240 or other elements (e.g., the scan function activating module 220, the memory 250, the input/output interface 260, the display 270, the communication interface 280, and the like). The memory 250, for example, may include programming modules such as a kernel 251, middleware 253, an Application Programming Interface (API) 255, or an application 257. Each of the programming modules may be configured by software, firmware, hardware, or a combination of two or more thereof.


The input/output interface 260 transfers an instruction or data input from a user through an input device (e.g., a sensor, a keyboard, or a touch screen), to the scan function activating module 220, the processor 240, the memory 250, or the communication interface 280 through, for example, the bus 210. For example, the input/output interface 260 provides, to the processor 240, data associated with a touch of a user input through a touch screen.


The display 270 displays various pieces of information (e.g., multimedia data, text data, etc.) to a user. For example, the display 270 displays instructions or data received from the scan function activating module 220, the processor 240, the memory 250 and the communication interface 280 through the bus 210.


The communication interface 280 establishes communication between the first electronic device 201 and an external device (e.g., the server 301 or the second electronic device 401). For example, the communication interface 280 is connected to a network 282 through wireless communication, and communicates with the server 301 or the second electronic device 401. For example, the wireless communication may include at least one of Wireless Fidelity (Wi-Fi), Bluetooth (BT), Bluetooth Low Energy (BLE), Near Field Communication (NFC), a satellite communication (e.g., a GPS), or a cellular communication (e.g., Long Term Evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telephone System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communication (GSM), or the like).


According to an embodiment of the present disclosure, the first electronic device 201 transmits the scan time information of the first electronic device 201 and identification of the information to be scanned by the first electronic device 201 (i.e., the information to be transmitted by the second electronic device 401) to the server 301 through a Wi-Fi module. In addition, the first electronic device 201 receives an advertisement message (i.e., the information to be scanned by the first electronic device 201) from the second electronic device 401 through a Bluetooth Low Energy (BLE) module or a Bluetooth (BT) module.


According to an embodiment of the present disclosure, a protocol (e.g., a transport layer protocol, a data link layer protocol or a physical layer protocol) for a communication among the first electronic device 201, the server 301 and the second electronic device 401 may be supported by at least one of the application 257, the API 255, the middleware 253, and the kernel 251, which is included in the memory 250, or the communication interface 280.



FIG. 3 is a block diagram of a server 301 according to an embodiment of the present disclosure.


Referring to FIG. 3, the server 301 includes a communication interface 303, a processor 305 and a memory 307.


The communication interface 303 establishes a communication between the server 301 and an external device (e.g., the first electronic device 201 or the second electronic device 401). For example, the communication interface 303 is connected to a network through a wireless communication, and communicates with the first electronic device 201 or the second electronic device 401. For example, the wireless communication includes at least one of Wireless Fidelity (Wi-Fi), Bluetooth (BT), Bluetooth Low Energy (BLE), Near Field Communication (NFC), a satellite communication (e.g., a GPS), or a cellular communication (e.g., LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, GSM, or the like).


The communication interface 303, according to an embodiment of the present disclosure, receives the scan time information of the first electronic device 201 (i.e., the times when the first electronic device 201 scans for a transmission sent to it by a second electronic device 401) and the identification of information to be scanned by the first electronic device 201 (i.e., identification of what the second electronic device 401 will transmit to the first electronic device 201), from the first electronic device 201, and transmits the scan time information of the first electronic device 201 and the identification of the information to be scanned by the first electronic device 201 to at least one second electronic device 401 registered in the server 301.


The processor 305 controls the overall operation of the server 301. In this case, the processor 305, according to an embodiment of the present disclosure, controls the server 301 to receive the scan time information of the first electronic device 201 and the identification of the information to be scanned by the first electronic 201 device from the first electronic device 201 and transmits the received information to the second electronic device 401. When the first electronic device 201 attempts to scan for information from two or more second electronic devices 401, the processor 305 controls the server 301 to transmit the identification of the information to be scanned by the first electronic device 201 (i.e., the identification of what a second electronic device is to transmit to the first electronic device 201) and the scan time information of the first electronic device 201 (i.e., the time when the first electronic device will be scanning for a transmission from a second electronic device 401) to two or more second electronic devices 401. For example, as a result of the identification of the information to be scanned by the first electronic device 201, when the first electronic device 201 desires to receive information from a second electronic device “A” 201 (e.g. a transmission from the second electronic device “A” 201) and information from another second electronic device “B′” 201 (e.g. a transmission from the other second electronic device “B” 201), the processor 305 controls the server 301 to transmit to the second electronic device “A” and the other second electronic device “B,” respectively, the scan time information of the first electronic device 201 and the identification of the information to be transmitted by the second electronic device “A” 201 and the identification of the information to be transmitted by the other second electronic device “B” 201. In this case, the scan times may be different for the information to be transmitted by the second electronic device “A” 201 and the information to be transmitted by the other second electronic device “B” 201.


The memory 307 stores instructions or data received from the processor 305 and the communication interface 303 or instructions or data generated by the processor 305 and the communication interface 303. The memory 307 may include programming modules such as a kernel, middleware, an Application Programming Interface (API), or an application. Each of the programming modules may be configured by software, firmware, hardware, or a combination of two or more thereof. The memory 307, according to an embodiment of the present disclosure, stores information for at least one second electronic device 401 registered in the server 301.



FIG. 4 is a block diagram of a network environment 400 including a second electronic device 401 according to an embodiment of the present disclosure.


Referring to FIG. 4, the second electronic device 401 includes a bus 410, an advertisement message transmitting module 420, a processor 440, a memory 450, an input/output interface 460, a display 470, and a communication interface 480.


The bus 410 connects elements of the second electronic device 401 for transferring a communication (e.g., a control message) among the elements of the second electronic device 401.


The advertisement message transmitting module 420 receives scan time information of a first electronic device 201 and identification of information to be scanned by the first electronic device 201 from a server 301. Then, the advertisement message transmitting module 420 determines a time when an advertisement message is to be transmitted to the first electronic device 201 based on the scan time information.


Then, the advertisement message transmitting module 420 transmits the advertisement message which corresponds to the information to be scanned by the first electronic device 201 to the first electronic device 201 at the determined time (e.g. during the scan time of the first electronic device 201). That is, the advertisement message transmitting module 420 broadcasts the advertisement message which corresponds to the information to be scanned by the first electronic device 201 at the determined time (e.g. the scan time of the first electronic device 201) to enable the first electronic device 201 to receive the advertisement message.


The processor 440, for example, receives instructions from other elements (e.g., the advertisement message transmitting module 420, the memory 450, the input/output interface 460, the display 470, the communication interface 480, and the like) through the bus 410, decodes the received instructions, and executes an operation or processes data according to the decoded instructions.


The memory 450 stores instructions or data received from the processor 440 or other elements (e.g., the advertisement message transmitting module 420, the memory 450, the input/output interface 460, the display 470, the communication interface 480, and the like) or generated by the processor 440 or other elements (e.g., the advertisement message transmitting module 420, the memory 450, the input/output interface 460, the display 470, the communication interface 480, and the like). The memory 450, for example, includes programming modules such as a kernel 451, middleware 453, an Application Programming Interface (API) 455, or an application 457. Each of the programming modules may be configured by software, firmware, hardware, or a combination of two or more thereof.


The input interface 460 transfers an instruction or data input from a user through an input device (e.g., a sensor, a keyboard, or a touch screen), to the advertisement message transmitting module 420, the processor 440, the memory 450, or the communication interface 480 through, for example, the bus 410. For example, the input/output interface 460 provides, to the processor 440, data associated with a touch of a user input through a touch screen.


The display 470 displays various types of information (e.g., multimedia data, text data, etc.) to a user. For example, the display 470 displays instructions or data received from the advertisement message transmitting module 420, the processor 440, the memory 450 and the communication interface 480 through the bus 410.


The communication interface 480 establishes communication between the second electronic device 401 and an external device (e.g., the server 301 or the first electronic device 201). For example, the communication interface 480 is connected to a network 482 through wireless communication, and communicates with the server 301 or the first electronic device 201. For example, the wireless communication includes at least one of Wireless Fidelity (Wi-Fi), Bluetooth (BT), Bluetooth Low Energy (BLE), Near Field Communication (NFC), a satellite communication (e.g., a GPS), or a cellular communication (e.g., LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, GSM, or the like).


According to an embodiment of the present disclosure, a protocol (e.g., a transport layer protocol, a data link layer protocol or a physical layer protocol) for communication among the second electronic device 401, the server 301 and the first electronic device 201 is supported by at least one of the application, the API, the middleware, the kernel included in the memory 450, or the communication interface 480.


According to an embodiment of the present disclosure, the second electronic device 401 receives the scan time information of the first electronic device 201 and identification of the information to be scanned by the first electronic device 201 from the server 301 through a Wi-Fi module. In addition, the second electronic device 401 transmits an advertisement message to the first electronic device 201 through a Bluetooth Low Energy (BLE) module or a Bluetooth (BT) module.



FIG. 5 is a flowchart of a method of a first electronic device 201 according to an embodiment of the present disclosure.


Referring to FIG. 5, in step 501, the first electronic device 201 may receive information indicating scan time information of the first electronic device 201 and an identification of information to be scanned by the first electronic device 201. In this case, the scan time may include a time when the scan function of the first electronic device 201 is activated (e.g. a time to start a scan), and a period during which the scan function scans for information (e.g. a duration of the scan). The identification of information to be scanned by the first electronic device 201 may include a type, a kind, an item and/or a clause related to the information to be scanned, and may further include the identity of the second electronic device 401 that is to transmit the information to be scanned.


Next, in step 503, the first electronic device 201 transmits the scan time information and the identification of the information to be scanned to a server. In an embodiment of the present disclosure, the scan time information and the identification of the information to be scanned are transmitted to the server based on a first communication method (e.g., a Wi-Fi communication module).


Then, in step 505, the first electronic device 201 activates the scan function at the scan time.

In step 817, the second electronic devices 805-1 to 805-N identify the scan time information of the first electronic device and the, respective, information to be scanned by the first electronic device 801 (e.g. the information to be transmitted by the second electronic device 805-1 and the information to be transmitted by the other second electronic device 805-2, respectively).


In step 819, the second electronic devices 805-1 to 805-N each determine a time when an advertisement message is transmitted from the second electronic devices 805-1 to 805-N, respectively, based on the scan time information.


In step 821, the first electronic device 801 activates a scan function at the scan time, respectively. That is, the first electronic device 801 activates the scan function at the scan time, respectively, in order to receive the advertisement messages from the second electronic devices 805-1 to 805-N, respectively.


Then, in step 823, the second electronic devices 805-1 to 805-N each broadcast their advertisement message corresponding to the information to be scanned, and the first electronic device 801 receives each corresponding advertisement message.


Then, when a scan period expires, the first electronic device 801, in step 825, deactivates the scan function.
