[0002] By Bluetooth TM Bluetooth SIG TM The standard technology defines the protocol for short-range wireless communication between electronic devices. TM In a network environment, electronic devices may transmit or receive data packets containing content such as text, voice, image, or video in a designated frequency band (eg, approximately 2.4 gigahertz (GHz)).

[0003] For example, a user equipment (UE) such as a smartphone, tablet, desktop, or laptop computer can send data packets to another UE or an accessory device. The accessory device can include, for example, at least one of an earphone, a headset, a wearable device, a speaker, a mouse, a keyboard, and / or a display device. Summary of the invention

[0004] Technical issues

[0005] In the Bluetooth TM In the topology of the network environment, the electronic device can query at least one external electronic device and display the query result through the display. Because the electronic device can perform queries on multiple external electronic devices within a specified time, the electronic device can display a query list including multiple queried external electronic devices.

[0006] Electronic devices can be based on Bluetooth TM The electronic device may establish a link with the external electronic device desired by the user among the multiple queried external electronic devices.

The communication module 190 may include one or more communication processors CP capable of operating independently from the processor 120 (e.g., AP), and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 includes a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) and a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth (Bluetooth)). TM), Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)), or a second network 199 (e.g., a long-distance communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))) to communicate with an external electronic device. These various types of communication modules can be implemented as a single component (e.g., a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can use the user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify and authenticate the electronic device 101 in the communication network (such as the first network 198 or the second network 199).

[0051] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, a general purpose input output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0052] According to an embodiment, a command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 and the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type from the electronic device 101.

[0053] Figure 2 is a Bluetooth according to an embodiment TM Block diagram of a topology 200 of a network environment.

[0054] refer to Figure 2 , the first device 201 and the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 included in the topology 200 may perform functions that are the same as or similar to those of the electronic device 101, and may include components that are the same as or similar to those of the electronic device 101. For example, the first device 201 and the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 may include user devices such as smartphones, tablet computers, desktop computers, or laptop computers, or accessory devices such as earphones, headphones, speakers, mice, keyboards, or display devices.

[0055] The first device 201 and the second device 202-1, 202-2, 202-3, 202-4, and 202-5 may include a Bluetooth TM Bluetooth SIG definition TM In this case, the wireless communication circuit may include BluetoothTM Module and / or Bluetooth TM At least one of the chips. Bluetooth TM Protocols may include, for example, Bluetooth TM Traditional protocol and BLE protocol. The wireless communication circuit can support Bluetooth TM One or both of the traditional protocol and the BLE protocol.

[0056] The first device 201 can be based on Bluetooth TM The first device 201 is connected to at least one of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 by a protocol to provide various services to the user. For example, when at least one second device 202-1, 202-2, 202-3, 202-4, or 202-5 connected to the first device 201 is an accessory device, the first device 201 can provide at least one function of health care, hands-free calling, media playback, file sharing, and / or notification through at least one of the connected second devices 202-1, 202-2, 202-3, 202-4, or 202-5.

[0057] Before the first device 201 is connected to at least one of the second devices 202-1, 202-2, 202-3, 202-4, or 202-5, the first device 201 may connect to the at least one second device 202-1, 202-2, 202-3, 202-4, or 202-5 based on Bluetooth. TM The first device 201 may query (or discover) the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 through the query process within a specified time. For example, the first device 201 may query (or discover) the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 based on the Bluetooth protocol during a specified period of time. TM The conventional protocol sends an identification (ID) packet including an inquiry access code (IAC), and receives an FHS packet in response to the ID packet from the second devices 202-1, 202-2, 202-3, 202-4, and 202-5. For example, the first device 201 can receive an advertising packet or a scan response (SCAN_RSP) packet based on the BLE protocol from the second devices 202-1, 202-2, 202-3, 202-4, and 202-5.

[0058] As described in more detail below Figure 3 or Figure 4 As shown, the first device 201 may output a query list indicating query results of the second devices 202 - 1 , 202 - 2 , 202 - 3 , 202 - 4 , and 202 - 5 through the display device 160 .

[0059] The first device 201 can establish a link 210-1 or 210-2 with at least one second device 202-1 or 202-2, respectively, the at least one second device 202-1 or 202-2 selected by user input from the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 included in the query list, and send or receive data through the established link. At least one of the second devices 202-3, 202-4, and 202-5 that do not have a link established with the first device 201 can monitor (or sniff) the link 210-1 or 210-2 established between the first device 201 and another second device 202-1 or 202-2 to receive data from the first device 201. In this case, at least one of the other second devices 202-3, 202-4, or 202-5 may receive information (eg, channel information and address information) associated with the link 210-1 or 210-2 from the second device 202-1 or 202-2 and monitor the link using the received information.

[0060] Figure 3 and Figure 4 User interfaces 310 and 410 showing query results are shown according to an embodiment.

[0061] refer to Figure 3 , the first device 201 may output a user interface 310 indicating the query results of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 through the display device 160 to inform the user of the external electronic devices that can establish a link with the first device 201. For example, the user interface 310 may have a list form in which the query results of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 are listed in a designated direction (e.g., a downward direction).

[0062] The first device 201 may indicate the query results of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 using information included in the FHS packet, the advertising packet, or the scan response packet received during the query process. For example, the user interface 310 may include a device name (e.g., device A, device B, device C, or device D), a manufacturer name, a Bluetooth TM The addresses or information of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 are included in the FHS packet, the advertisement packet, or the scan response packet.

[0063] The first device 201 may sequentially and descendingly display a plurality of queried second devices 202-1, 202-2, 202-3, 202-4, and 202-5 based on a specified condition. The specified condition may be based on, for example, at least one of received signal strengths (e.g., received signal strength indicators (RSSIs)) of FHS packets, advertising packets, or scan response packets received from the plurality of second devices, alphabetical order of device names, device types, and / or clock values.

[0064] When the first device 201 displays the query results of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 in order based on the received signal strength, because the strength of the transmitted signal of one of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 (e.g., a laptop computer that is always powered) may be high, the query result of the laptop computer may be displayed above the query result of one of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 (e.g., a headset) that the user wants to use. In this case, the readability or visibility of the second device that the user wants to use may be low for the user.

[0065] The first device 201 may display the query results based on the clock value sequence of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5. For example, when the order of the difference between the clock value and the specified value is the first clock value, the second clock value, the third clock value, and the fourth clock value from the smallest difference to the largest difference, and when device A has the third clock value, device B has the first clock value, device C has the fourth clock value, and device D has the second clock value, then the first device 201 may output the query results of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 in descending order according to the order of device B, device D, device A, and device C. Because based on Bluetooth TM The CLKN (local clock) of the protocol supports Bluetooth TMThe operation starts at the time point when the wireless communication circuit of the protocol is powered on, so it can indicate that one of the second devices 202-1, 202-2, 202-3, 202-4 and 202-5, whose value indicated by CLKN is close to 0x00, is a device in which the wireless communication circuit is turned on for user use (or connected to the first device 201). For example, because one of the second devices 202-1, 202-2, 202-3, 202-4 and 202-5 that receives user input in the second devices 202-1, 202-2, 202-3, 202-4 and 202-5 can change the operating clock to a specified value, it can indicate that one of the second devices 202-1, 202-2, 202-3, 202-4 and 202-5 whose clock value is close to the specified value is a device to be connected to the first device 201.

[0066] refer to Figure 4 , the first device 201 may output the query result considering at least one condition among the clock values, received signal strengths, alphabetical order of the device names, and / or device types of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5. For example, the first device 201 may sort the first group (e.g., device E, device F, device G, and device H) whose received signal strengths are greater than or equal to a first threshold (e.g., -65dBm), the second group (e.g., device A and device B) whose received signal strengths are less than the first threshold and greater than or equal to a second threshold (e.g., -80dBm), and the third group (e.g., device C and device D) whose received signal strengths are less than the second threshold. Thereafter, the first device 201 may arrange the devices included in each group in alphabetical order of the device names. Thereafter, the first device 201 may display the query result of the device (e.g., device F) having a clock value close to the specified value among the queried second devices 202-1, 202-2, 202-3, 202-4, and 202-5 at the top. although Figure 4 An embodiment is shown in which the first device 201 displays the queried second devices in the order of received signal strength, alphabetical order of device name, and order of clock value in the specified condition, but the order of considering the specified condition is only an example, and the order of considering the specified condition may be changed. Figure 4 An embodiment using multiple thresholds (eg, a first threshold and a second threshold) is shown. However, the first device 201 may use one threshold (eg, one of the first threshold and the second threshold) to sequentially display the queried second devices 202-1, 202-2, 202-3, 202-4, and 202-5.

[0070] The master and slave devices can align the packet transmission and reception points in time based on the clock. TM The clocks of the protocol may include a reference clock (CLKR), a local clock (CLKN), an estimated clock (CLKE), and a master clock (CLK). CLKR is a system clock generated by the system of the electronic device, which can be used as a reference for other clocks. CLKN can start from 0x0 with CLKR as a reference at the time when the wireless communication circuit is powered on. For example, the master device and the slave device can operate CLKN by applying a time_base_offset to CLKR.

[0071] CLK can be used for synchronization between electronic devices. In this case, channel resources (e.g., frequency hopping channels) for sending packets can be generated based on the CLKN of the master device. TM In a conventional network, time resources (eg, time slots) may be determined based on the CLKN of the master device. The time slot may be, for example, 625 us (microseconds). The slave device is synchronized by applying an offset to the CLKN of the master device, and the CLKN of the master device may be CLK.

[0072] Figure 6 is a signal flow diagram 600 for displaying a query list based on clock information according to an embodiment. The second device 202 may be one of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5.

[0073] refer to Figure 6 In step 605, the second device 202 may enable a query mode. The query mode may indicate a mode for performing a query process. The enabling of the query mode may indicate, for example, enabling a Bluetooth-based TM Inquiry scanning of traditional protocols or advertising based on BLE protocol.

[0074] The second device 202 may enable the inquiry mode in response to powering on the second device 202, powering on the wireless communication circuit of the second device 202, or opening of a housing device including the second device 202. TM When a user input of a protocol request service is received, an application associated with the first device 201 is installed on the second device 202, or the application is executed, the second device 202 may enable the query mode. When the query mode is enabled, the clock (e.g., CLKN) of the second device 202 may start operating. The clock may start from a specified value (e.g., 0x0).

[0075] In step 615, when the clock is running, the second device 202 may receive a first control packet for the query process from the first device 201. For example, the first control packet may include a Bluetooth-based TM The first control packet may include an ID packet of a traditional protocol or a scan request (SCAN_REQ) packet based on a BLE protocol. The first control packet may include an IAC. The first device 201 may broadcast the first control packet.

[0076] In step 620, the second device 202 may send a second control packet in response to the first control packet to the first device 201. The second control packet may include, for example, a Bluetooth-based TM The FHS packet of the traditional protocol or the scan response packet based on the BLE protocol. The second device 202 can insert clock information about the clock operated from step 605 into the second control packet. For example, the second device 202 can identify the clock value operated based on step 605 in response to the reception of the first control packet. The identified clock value can be inserted into the second control packet.

[0077] In step 625, the first device 201 may display a query list indicating the query results of the second device 202 based on the clock information included in the second control packet. For example, the first device 201 may display at the top the query result of one of the second devices 202-1, 202-2, 202-3, 202-4, and 202-5 having a clock value close to the designated value among the clock values ​​of the second device 202 and the clock values ​​of the other second devices 202-1, 202-2, 202-3, 202-4, and 202-5.

For example, the first device 201 may send (e.g., broadcast) an ID packet multiple times (e.g., twice) during a time slot (e.g., a TX time slot), and then attempt to receive an FHS packet during a next time slot (e.g., a RX time slot). For example, the ID packet may be generated based on a general IAC (GIAC).

[0080] The first device 201 may perform the query process based on the conditions for starting the query process. For example, the first device 201 may respond to the first device 201 entering the Bluetooth setting application. TM The query process is performed by selecting a menu, receiving a user input requesting a specific service (e.g., file sharing), installing an application associated with the second device 202 on the first device 201, or executing the application. The first device 201 can perform a query process of repeatedly sending an ID packet (e.g., a TX operation) and opening a receiving time slot (e.g., a RX operation) for a specified time (e.g., 12.8 seconds).

[0081] In step 705, the second device 202 may enable inquiry scanning. When the inquiry scanning is enabled, the second device 202 may attempt to receive an ID packet including a GIAC by opening a receiving time slot.

[0082] When the second device 202 is powered on, the wireless communication circuit of the second device 202 is powered on, or the housing device including the second device 202 is opened, the second device 202 can enable the inquiry scan. In this case, when the inquiry scan is enabled, the CLKN of the second device 202 can start operating from a specified value (e.g., 0x0). The second device 202 can enable the inquiry scan when a user input requesting a specific service (e.g., file sharing) with the first device 201 is received, an application associated with the first device 201 is installed on the second device 202, or the application is executed. In this case, the second device 202 can reset the CLKN value that has been running to the specified value.

[0084] In step 715, the second device 202 may send an FHS packet in response to the ID packet to the first device 201. The second device 202 may insert clock information (e.g., CLKN) into the FHS packet. For example, the second device 202 may insert an increasing CLKN value into the FHS packet starting from when the inquiry scan is enabled until the ID packet is received (or until the transmission of the FHS packet starts).

[0085] In step 720, the first device 201 may receive FHS packets from at least one second device 202-1, 202-2, 202-3, 202-4, and 202-5, and display a query list including at least one second device 202-1, 202-2, 202-3, 202-4, and 202-5 based on a CLKN value included in the received FHS packet.

[0087] refer to Figure 8 The data format of the FHS packet 800 may be a first data format 850 including a parity bit field 801 to a page scan mode field 812 , or a second data format 860 further including an additional field 813 in the first data format 850 .

[0088] At least some of the field types and bit sizes of the first data format 850 may be based on Bluetooth TM For example, the FHS packet 800 may include a parity bit field 801 (e.g., 34 bits), a lower address part (LAP) field 802 (e.g., 24 bits), an extended inquiry response (EIR) field 803 (e.g., 1 bit), a reserved field 804 (e.g., 1 bit), a scan repetition (SR) field 805 (e.g., 2 bits), a scan period (SP) field 806 (e.g., 2 bits), an upper address part (UAP) field 800, a non-significant address part (NAP) field 808 (e.g., 16 bits), a device type field 809 (e.g., 24 bits), a logical transfer (LT) address (LT_ADDR) field 810 (e.g., 3 bits), a CLK27-2 field 811 (e.g., 26 bits), and a page scan mode field 812 (e.g., 3 bits).

[0089] The parity bit field 801 may be located at the front of the FHS packet and may be used for error detection. The EIR field 803 may indicate whether the second device 202 supports the EIR packet transmission function. The reserved field 804 may indicate whether the Bluetooth TMThe fields not defined by the standard. The UAP field 807 and the NAP field 808 indicate the manufacturer's code (e.g., an organizational unique identifier (OUI)), while the LAP field 802 may indicate a code assigned by the manufacturer. The SR field 805 may indicate the interval between consecutive page scan windows. The SP field 806 may indicate a scan period. The device category field 809 may indicate the category of the second device 202 (e.g., headphones, headsets, wearable devices, speakers, mice, keyboards, or display devices). The LT address field 810 may indicate a logical transmission address for a connection or role switching between the first device 201 and the second device 202. The CLK27-2 field 811 may indicate the CLKN value of the second device 202. The page scan mode field 812 may indicate which scan mode the second device 202 uses.

[0090] Because the first device 201 can display the query list based on the CLKN value of the second device 202 inserted into the CLK27-2 field 811, the first device 201 can identify the device that the user wants to use even when the second device 202 does not insert the additional data bit. When the FHS packet 800 includes the additional field 813 based on the second data format 860, the second device 202 can insert the reset clock value into the additional field 813.

[0096] When active scanning is used, in step 915, the first device 201 may send a scan request packet (SCAN_REQ) to the second device 202. From when advertising is enabled until the scan request packet (SCAN_REQ) is received (or until the transmission of the scan request packet (SCAN_REQ) begins), the second device 202 may insert an increasing clock value into the scan request packet (SCAN_REQ), and in step 920, may send a scan response packet (SCAN_RSP) to the first device 201.

[0097] In step 925 , the first device 201 may display a query list based on a clock value included in a scan response packet (SCAN_RSP) received from at least one of the second devices 202 (eg, 202 - 1 , 202 - 2 , 202 - 3 , 202 - 4 , and 202 - 5 ).

In step 1105, the second device 202 may be powered on, or the wireless communication circuit of the second device 202 may be powered on. When the second device 202 is powered on or when the wireless communication circuit of the second device 202 is powered on, the clock may start operating. For example, when the second device 202 is powered on, CLKR may start operating. For example, when the wireless communication circuit of the second device 202 is powered on, CLKN may start operating. When the pairing mode is activated, the wireless communication circuit of the second device 202 may be powered on. For example, when a user input (e.g., a long touch) of pressing a button placed on one side for a specified time is received while the second device 202 is powered on, the wireless communication circuit of the second device 202 may be powered on. When the second device 202 or the wireless communication circuit of the second device 202 is powered on, the clock may start operating from 0x0.

[0102] In step 615, the second device 202 may receive a first control packet for a query process from the first device 201 when the clock is operating.

[0103] refer to Fig.12 , at least one accessory device 1202-1 or 1202-2, which may be the second device 202, may be inserted into the housing device 1203. The accessory device 1202-1 or 1202-2 may include, for example, a wireless headset. In step 1205, the housing device 1203 into which the at least one accessory device 1202-1 or 1202-2 is inserted may be opened. When the housing device 1203 is opened, the clock of the at least one accessory device 1202-1 or 1202-2 may start operating. When the at least one accessory device 1202-1 or 1202-2 is separated from the housing device 1203, or when a user input (e.g., a long touch) is received by pressing a button provided on one side of the housing device 1203 for a specified time, the clock of the at least one accessory device 1202-1 or 1202-2 may start operating. The clock may start operating from 0x0.

In step 620, at least one accessory device 1202-1 or 1202-2 may send a second control packet corresponding to the first control packet to the first device 1201. At least one accessory device 1202-1 or 1202-2 may insert clock information about the clock that starts operating at a time point in step 1205 (or at a time point at which at least one accessory device 1202-1 or 1202-2 is separated from the shell device 1203 or at a time point at which a user input of pressing a button on a side of the shell device 1203 is received) into the second control packet. In step 625, the first device 1201 may display a query list indicating a query result of the at least one accessory device 1202-1 or 1202-2 based on the clock information included in the second control packet.

[0105] Fig.13a and 13b An operation scenario 1300 of resetting a clock according to an embodiment is shown. The first device 1301 and the second device 1302 may each be a user equipment.

[0106] refer to Fig.13a , the first device 1301 may receive a user input 1310 requesting to share a file with the second device 1302. The second device 1302 may receive a user input 1320 accepting sharing of the file with the first device 1301. Fig.13a In the example, the first device 1301 requests file sharing, but the second device 1302 may request file sharing, and the first device 1301 may accept file sharing. In response to receiving the user input 1320, the second device 1302 may reset the clock (eg, CLKN) operated in step 1330 to a specified value.

[0107] For example, the first device 1301 may display a plurality of images in response to a user input for executing a gallery application. The first device 1301 may receive a user input for selecting at least one of the plurality of displayed images, and receive a user input 1310 for querying the second device 1302 to share at least one selected image. The second device 1302 may execute the gallery application, and receive a user input 1320 for requesting to receive at least one image from the first device 1301 while displaying an execution screen of the gallery application.

The request message may include, for example, at least one of an ID packet and a scan request packet, or may include separate packets. The first device 1301 may send the request message in response to receiving the user input 1310.

[0109] In response to receiving the request message, in step 1350, the second device 1302 may send a reset clock value to the first device 1301. For example, the second device 1302 may send the clock value via an FHS packet, an advertisement packet, or a scan response packet, or via a separate packet. In this case, the second device 1302 may send an increased clock value from when the clock is reset until when the request message is received.

For example, the second device 1302 may reset the clock in response to receiving the user input 1320 in step 1330, and send the reset clock value to the first device 1301 without waiting for the request message. After the second device 1302 resets the clock in response to receiving the user input 1320 in step 1330, the first device 1301 may receive the user input 1310 and then send the request message to the second device 1302 in step 1340. When the first device 1301 sends the request message in response to the user input 1310 in step 1340, the second device 1302 that receives the request message may receive the user input 1320 of accepting file sharing in step 1330 to reset the clock, and send the reset clock value to the first device 1301 in step 1350.

[0111] refer to Fig.13b , the first device 1301 can use the received clock value to display the query result of the second device 1302 on the display. For example, when the clock value of the second device 1302 is closest to the specified value, the first device 1301 can output the query result of the second device 1302 above the query results of other devices (e.g., device A and device B).

[0112] In step 1360, the first device 1301 may receive a user input 1360 selecting the second device 1302 through the display. In step 1370, in response to the user input 1360, the first device 1301 may TM The protocol establishes a link with the second device 1302. When the establishment of the link is completed, in step 1380, the first device 1301 and the second device 1302 can send data to another person's device through the link.

[0116] In step 1415, the electronic device may identify the clock value of the external electronic device included in the second control packet through the processor. For example, when the wireless communication circuit receives the second control packet, the wireless communication circuit may send the second control packet (or the clock value included in the second control packet) to the processor.

[0117] In step 1420, the electronic device may display a user interface indicating the query results of the plurality of external electronic devices based on the clock value identified by the processor. For example, the electronic device may display the query results of the external electronic devices sequentially, vertically, and descendingly in the order of the difference between the clock value and the specified value, from the smallest difference to the largest difference.
