Description

Technical Field

[0001] The present disclosure relates to an electronic device and a method thereof for sending a response message in a Bluetooth network environment. Background Art

[0002] The Bluetooth standard technology defined by the Bluetooth Special Interest Group (SIG) defines a protocol for short-range wireless communications between electronic devices. In a Bluetooth network environment, electronic devices can send or receive data packets containing content (such as text, voice, images, or video) in a specified frequency band (e.g., approximately 2.4 gigahertz (GHz)).

[0003] For example, a user equipment (UE) such as a smartphone, tablet, desktop computer or laptop computer can send data packets to another user terminal or an accessory device. The accessory device can include at least one of, for example, earphones, headphones, speakers, a mouse, a keyboard or a display device.

[0004] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art to the present disclosure. Summary of the invention

[0005] Technical Solution

[0006] The topology representing the Bluetooth network environment may include one user device (e.g., device under test (DUT)) that sends data packets and multiple devices that receive data packets from the user device. For example, when an earphone (or headset) is connected to a smartphone, the earphone worn on the user's left ear and the earphone worn on the user's right ear can receive data packets from the smartphone.

[0007] Unless the multiple devices receiving the data packets are connected to each other in a wired manner, each of the multiple devices receiving the data packets may form a separate link with the user device. In this case, the user device needs to create multiple links to send the data packets, thus consuming resources, consuming power, and increasing the complexity of the user device. In addition, as the number of devices to which the user device must send data increases, the power consumption in the user device increases, and the time it takes for the data packet to reach the device increases.

[0008] Aspects of the present disclosure are intended to solve at least the above problems and / or disadvantages and provide at least the advantages described below. Accordingly, one aspect of the present disclosure is to provide an electronic device and method thereof for solving problems in a Bluetooth network.

The memory can store instructions, and when the instructions are executed, at least one processor: creates a link with an external electronic device based on the Bluetooth network through the wireless communication circuit; sends a data packet including content to the external electronic device through the wireless communication circuit; identifies whether the external electronic device supports a resource control function; when the external electronic device does not support the resource control function, receives at least one response message to the data packet through a pre-allocated first time resource; and when the external electronic device supports the resource control function, receives multiple response messages to the data packet through a second time resource obtained by changing at least a portion of the first time resource.

[0011] According to another aspect of the present disclosure, an electronic device is provided. The electronic device includes a wireless communication circuit supporting a Bluetooth network, at least one processor, and a memory operably connected to the at least one processor. The memory can store instructions, which, when executed, enable at least one processor to: create a first link with a first external electronic device based on the Bluetooth network through the wireless communication circuit; send resource control information to the first external electronic device to change the resources used to send data packets; create a second link with a second external electronic device based on the Bluetooth network, and send information associated with the first link to the second external electronic device; receive a data packet including content from the first external electronic device; and send a response message to the data packet to the first external electronic device based on the resource control information, by changing the second time resource obtained by at least a portion of the pre-allocated first time resource.

[0012] According to another aspect of the present disclosure, an electronic device is provided. The electronic device includes a wireless communication circuit supporting a Bluetooth network, at least one processor, and a memory operably connected to the at least one processor. The memory can store instructions that, when executed, cause at least one processor to: create a first link with a first external electronic device based on a Bluetooth network; receive information associated with a second link formed between the first external electronic device and the second external electronic device from the first external electronic device; based on at least a portion of the information associated with the second link, receive a data packet including content by monitoring the second link; and based on at least a portion of the information associated with the second link, send a response message in response to the data packet to the second external electronic device.

[0056] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. The communication module 190 may include one or more communication processors that operate independently of the processor 120 (e.g., an application processor (AP)) and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include 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) or 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 be connected via a first network 198 (e.g., such as Bluetooth TMThe wireless communication module 192 can communicate with an external electronic device in a first network 198 or a second network 199 (for example, a short-range communication network such as a wireless cellular network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (for example, a single chip), or can be implemented as multiple components (for example, multiple chips) separated from each other. The wireless communication module 192 can use the subscriber information (for example, the International Mobile Subscriber Identity (IMSI)) stored in the subscriber 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).

According to an embodiment, the antenna module 197 may include a plurality of antennas. In this case, for example, the communication module 190 (e.g., the wireless communication module 192) may select at least one antenna suitable for a communication scheme used in a communication network (such as the first network 198 or the second network 199) from a plurality of antennas. Then, the signal or power may be sent or received between the communication module 190 and the external electronic device via the selected at least one antenna.

[0061] It should be understood that the various embodiments of the present disclosure and the terms used therein are not intended to limit the technical features set forth herein to specific embodiments, but rather include various variations, equivalents, or substitutes of the corresponding embodiments. With respect to the description of the accompanying drawings, similar reference numerals may be used to refer to similar or related elements. As used herein, each of phrases such as "A or B," "at least one of A and B," "at least one of A or B," "A, B or C," "at least one of A, B and C," and "at least one of A, B or C" may include any one or all possible combinations of the items listed together in a corresponding phrase. As used herein, terms such as "first" and "second" or "1st" and "2nd" may be used to simply distinguish a corresponding component from another component, and do not limit the component in other respects (e.g., importance or order). It should be understood that if an element (e.g., a first element) is referred to as being “coupled with another element (e.g., a second element)”, “coupled to another element (e.g., the second element)”, “connected with another element (e.g., the second element)”, or “connected to another element (e.g., the second element)” with or without the term “operably” or “communicatively”, it means that the element can be coupled with the other element directly (e.g., by wire), wirelessly, or via a third element.

[0062] As used herein, the term "module" may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with other terms, such as "logic," "logic block," "component," or "circuit."

[0066] Figure 2is a diagram showing the topology of a Bluetooth network environment according to an embodiment of the present disclosure.

[0067] refer to Figure 2 The user device 201 and the devices 202-1, 202-2 and 202-3 included in the topology 200 may include Figure 1 At least some components of the electronic device 101 shown are the same or similar, or at least some functions that are the same or similar to the functions of the electronic device 101. For example, the user device 201 and the devices 202-1, 202-2, and 202-3 can perform short-range wireless communication through a Bluetooth network defined by the Bluetooth SIG. The Bluetooth network may include a Bluetooth traditional network and a Bluetooth low energy (BLE) network. The user device 201 and the devices 202-1, 202-2, and 202-3 perform wireless communication through one or both of the Bluetooth traditional network and the BLE network.

[0068] The user device 201 may include, for example, a user terminal such as a smartphone, a tablet computer, a desktop computer, or a laptop computer, and the devices 202-1, 202-2, and 202-3 may include accessory devices such as earphones, headphones, speakers, mice, keyboards, or display devices. The devices 202-1, 202-2, and 202-3 may pre-identify a counterpart device (e.g., a first device 202-1, a second device 202-2, or a third device 202-3), or store information (e.g., address information) on the paired device in advance. For example, when the first device 202-1 and the second device 202-2 are paired (sets) of accessory devices (e.g., earphones), the first device 202-1 and the second device 202-2 may pre-identify each other or pre-store each other's address information.

[0069] User device 201 can function as a master device, and devices 202-1, 202-2, and 202-3 can function as slave devices. The number of devices functioning as slave devices is not limited to Figure 2 The master device or the slave device may be determined in the process of creating a link between the devices (e.g., reference numerals 205, 215-1, or 215-2). According to another embodiment of the present disclosure, one of the first device 202-1 and the second device 202-2 (e.g., the first device 202-1) is used as the master device, and the remaining one of the first device 202-1 and the second device 202-2 is used as the slave device.

[0070] The master device can control the physical channel. For example, although the master device can send data packets, the slave device can send data packets to the master device only after receiving the data packets. In another example, channel resources (e.g., frequency hopping channels) for sending data packets can be generated based on the clock of the master device. In a Bluetooth traditional network, time resources (e.g., time slots) can be determined based on the clock of the master device. The time slot can be, for example, 625 μs (microseconds). In a BLE network, the master device and the slave device can send data packets at specified intervals, and if a data packet is received, a response is made after a specified time (e.g., inter-frame space (T_IFS), approximately 150 μs).

[0071] The user device 201 may send data packets including content such as text, voice, image or video to the devices 202-1, 202-2 and 202-3. Even at least one of the devices 202-1, 202-2 or 202-3 may send data packets like the user device 201, depending on the type of content included in the data packets. For example, when music is reproduced in the user device 201, data packets may be sent only by the user device 201. When the user device 201 makes a call, even at least one of the devices 202-1, 202-2 or 202-3 may send data packets including content (e.g., voice data) to the user device 201 like the user device 201. When only the user device 201 sends data packets, the user device 201 may be referred to as a source device, and the devices 202-1, 202-2 and 202-3 may be referred to as sink devices.

[0072] When the user device 201 creates (or establishes) multiple links with devices 202-1, 202-2, and 202-3 to send data packets, resource consumption and power consumption in the user device 201 may increase. Accordingly, the user device 201 may only establish a first link 205 with the first device 202-1, and may send data packets to the first device 202-1 through the first link 205. In this case, at least one other device (e.g., reference numeral 202-2 or 202-3) may monitor the first link 205 to receive data packets including content. In this case, the user device 201 may be referred to as a device under test (DUT), the first device 202-1 may be referred to as a primary earbud (PE) or a primary equipment (PE), and at least one other device (e.g., reference numeral 202-2 or 202-3) may be referred to as an auxiliary earbud (or auxiliary equipment).

[0073] According to an embodiment of the present disclosure, the first device 202-1 may establish a second link 215-1 with the second device 202-2. The first device 202-1 may send information associated with the first link 205 to the second device 202-2 through the second link 215-1, so that the second device 202-2 monitors the first link 205 and sends a response message to the user equipment 201. The information associated with the first link 205 may include address information (e.g., a Bluetooth address of a master device of the first link 205, a Bluetooth address of the user equipment 201, and / or a Bluetooth address of the first device 202-1), piconet clock information (e.g., a local clock (CLKN) of the master device of the first link 205), logical transport (LT) address information (e.g., information allocated by the master device of the first link 205), use channel mapping information, link key information, service discovery protocol (SDP) information (e.g., service and / or profile information associated with the first link 205), and / or supported feature information. The information associated with the first link 205 may also include, for example, an extended inquiry response (EIR) packet. The EIR packet may include resource control information of the first link 205 and / or information about the manufacturer. The second device 202-2 may determine the hopping channel or frequency hopping channel of the first link 205 based on the address information and the clock information, and may decrypt the encrypted data packet based on the link key information. The second device 202-2 may generate an access code or a channel access code and address information (e.g., LT address information) corresponding to the first link 205 based on the information associated with the first link 205, and send a response message including the generated access code and address information to the user device 201. Even if the user device 201 does not establish a link with the second device 202-2, the user device 201 may determine whether to retransmit the data packet based on the response message sent from the second device 202-2.

[0074] In the same manner, the first device 202-1 can establish a third link 215-2 with the third device 202-3, and can send information associated with the first link 205 to the third device 202-3 through the third link 215-2. According to the embodiments described below, operations performed between the first device 202-1 and the second device 202-2 and principles associated with these operations can be applied to the first device 202-1 and the third device 202-3.

[0075] According to another embodiment of the present disclosure, when the first device 202-1 and the second device 202-2 support the same user account or similar user accounts (e.g., family accounts), the first device 202-1 and the second device 202-2 can share information associated with the first link 205 based on the same or similar user accounts through an external device (e.g., an external server 203) interconnected with the first device 202-1 or the second device 202-2. In this case, the topology 200 may further include the external server 203. For example, the first device 202-1 sends the information associated with the first link 205 to the external server 203, and the external server 203 sends the information associated with the first link 205 to the second device 202-2.

[0076] According to another embodiment of the present disclosure, the second device 202-2 may share information associated with the first link 205 with the user device 201. For example, the user device 201 may send information associated with the first link 205 to the second device 202-2 through a separate link (not shown), and may release the separate link when the sending of the information associated with the first link 205 is completed.

[0077] The first device 202-1 and the second device 202-2 may send a response message to the user equipment 201 to notify that the data packet is received normally. The response message may include a positive confirmation (ACK) message indicating that the data packet is received normally and a negative confirmation (NACK) message indicating that the data packet is not received normally. The response message may include, for example, 1 bit of information. When an ACK message is received after the data packet is sent, the user equipment 201 may send the next data packet. When a NACK message is received or a response message is not received within a specified time, the user equipment 201 may send the same data packet.

[0078] Although the second device 202-2 can send a response message to the first device 202-1 through the second link 215-1, the first device 202-1 can use a portion of the allocated resources to receive data packets from the user device 201. Accordingly, resources may be wasted. When a portion of the resources of the first device 202-1 are used, the user device 201 may not receive a response message, or the reception of the response message may be delayed. Accordingly, the performance of data packet transmission may be reduced or power consumption may increase. In addition, as the number of devices (e.g., 202-2 and 202-3) that have no link with the user device 201 increases, the time taken for the first device 202-1 to confirm that the data packet is received from other devices (e.g., 202-2 and 202-3) may increase.

[0079] The first device 202-1 and the user device 201 may change a portion of the pre-allocated resources so that the second device 202-2 sends a response message to the user device 201 without passing through the first device 202-1. For example, in a Bluetooth traditional network, half of the time slot (e.g., 0.625ms) pre-allocated to the first device 202-1 may be allocated to the second device 202-2. In another example, in a BLE network, at least some of the pre-allocated parameters may be changed to send data packets. For example, the parameters may include a parameter indicating an interval at which data packets are sent (e.g., TintV), a parameter indicating the number of devices receiving data packets (e.g., Npeers), a parameter indicating the time allocated to the device receiving the data packet (e.g., Tpeers), a parameter indicating the start instance of the data packet sending (e.g., Tstartinstance), a parameter indicating the order of the devices allocated to the received data packets (e.g., NpeersIndex), and a parameter indicating the timeout for the next data packet to be sent (e.g., TrdaTimeout). The above method can prevent performance degradation and power consumption of data packet transmission, and can cause the power of the first device 202-1 and the second device 202-2 to be consumed substantially evenly.

[0080] Figure 3 is a signal flow chart of sending a response message according to an embodiment of the present disclosure.

[0081] refer to Figure 3 In operation 305, the user device 201 may establish a first link with the first device 202-1 (eg, Figure 2 first link 205).

[0082] The user equipment 201 and the first device 202-1 may establish the first link 205 according to a procedure based on the Bluetooth standard. For example, the user equipment 201 and the first device 202-1 may perform procedures such as a baseband paging procedure for identifying a paired device, a link manager protocol (LMP) version, a clock offset, an LMP procedure for identifying supported functions (e.g., supported features), a host connection / response (request / response) procedure for confirming connectivity, an authentication procedure for verifying whether the paired device is a trusted device, an encryption procedure, and a setup completion procedure for notifying the host that the connection (e.g., the first link 205) is completed.

[0083] In operation 310, the first device 202-1 may send resource control information to the user equipment 201 to change at least a portion of the pre-allocated resources for sending data packets. For example, in a Bluetooth legacy network, the resource control information may indicate that the first device 202-1 supports a resource control function, or may indicate that the second device 202-2 is added. In another example, in a BLE network, the resource control information may include at least one parameter for sending data packets. The first device 202-1 may, when establishing a first link (e.g., Figure 2 The resource control information is sent before establishing the first link 205 or during establishing the first link 205.

[0084] In operation 315, the first device 202-1 may establish a second link with the second device 202-2 (eg, Figure 2 According to one embodiment, the first device 202-1 may establish the second link 215-1 with the second device 202-2 before establishing the first link 205 to the user equipment 201.

[0085] The first device 202-1 and the second device 202-2 may establish the second link 215-1 according to the Bluetooth standard-based procedure for establishing the first link 205. For example, the first device 202-1 and the second device 202-2 may perform a baseband paging procedure, an LMP procedure, a host connection / response procedure, an authentication procedure, an encryption procedure, and a setup completion procedure.

[0086] In operation 320, the first device 202-1 may send information associated with the first link 205 to the second device 202-2. The information associated with the first link 205 may include, for example, at least one of address information, clock information, channel information, SDP result information, information about supported functions, link key information, or an EIR packet. In another example, the information associated with the first link 205 may also include a parameter containing resource control information. The first device 202-1 may send information associated with the first link 205 to the second device 202-2 before establishing the second link 215-1 or during establishing the second link 215-1.

[0087] The first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message. For example, in a Bluetooth legacy network, the first device 202-1 and the second device 202-2 may determine that the first half of the pre-allocated time slot (e.g., Fig. 12A The device sending the response message in the second interval 1212) and the device sending the response message in the second half time slot (e.g., Fig. 12AIn another example, in the BLE network, the first device 202-1 and the second device 202-2 may negotiate at least one parameter (eg, TintV, Npeers, Tpeers, Tstartinstance, NpeersIndex, or TrdaTimeout).

[0088] The first device 202-1 and the second device 202-2 may negotiate resource information based on a device acting as a master device or a device (e.g., the first device 202-1) that transmits information associated with the first link 205. For example, when the first device 202-1 acts as a master device, the first device 202-1 and the second device 202-2 may determine that the first device 202-1 uses the first half-time slot. In another example, when the second device 202-2 receives information associated with the first link 205, the first device 202-1 and the second device 202-2 may determine that the second device 202-2 uses the second half-time slot.

[0089] The first device 202 - 1 and the second device 202 - 2 may negotiate resource information for sending a response message based on resource control information included in the information associated with the first link 205 .

[0090] The first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message separately from the resource control information. For example, the first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message during or after performing operation 315. In this case, the device sending the response message in the first half-time slot may be determined as a device (e.g., the first device 202-1) acting as a master device or a device (e.g., the second device 202-2) acting as a slave device (e.g., the second device 202-2). In another example, the first device 202-1 and the second device 202-2 may negotiate resource information based on a subject sending information associated with the first link 205. In this case, the device sending the response message in the first half-time slot may be determined as a device (e.g., the first device 202-1) sending information associated with the first link 205 or a device (e.g., the second device 202-2) receiving information associated with the first link 205.

[0091] In operation 325 , the user device 201 may transmit a data packet including content to the first device 202 - 1 through the first link 205 .

[0092] In operation 330, the second device 202-2 may monitor the first link 205 based on at least a portion of information associated with the first link 205 (e.g., address information or clock information). The second device 202-2 may receive the same data packet as the data packet received by the first device 202-1 through monitoring. Operation 330 may be referred to as shadowing or snooping.

[0093] In operation 335, the first device 202-1 may send a response message to the received data packet to the user equipment 201 through the first link 205. The response message may include, for example, an acknowledgement (ACK) message or a negative acknowledgement (NACK) message. The first device 202-1 may send the response message of the first device 202-1 based on the resources (hereinafter referred to as the second resources) obtained by changing at least a part of the pre-allocated resources (hereinafter referred to as the first resources) to avoid conflict with the response message sent by the second device 202-2. The second resource may be changed based on the resource control information sent from the first device 202-1 to the user equipment 201.

[0094] In operation 340, the second device 202-2 may send a response message to the data packet received in operation 330 to the user equipment 201 based on the information associated with the first link 205 received in operation 320. For example, the second device 202-2 may send the response message including the access code corresponding to the first link 205 through the resources indicated based on the resource control information (or resource information negotiated between the second device 202-2 and the first device 202-1).

[0095] Figure 4 is another signal flow diagram of sending a response message according to an embodiment of the present disclosure.

[0096] refer to Figure 4 , the external server 203 may include an external device interconnected with the first device 202-1 or the second device 202-2 based on a user account that is the same as or similar to a user account of the first device 202-1 or the second device 202-2.

[0097] refer to Figure 4 In operation 405, the user device 201 may establish a first link with the first device 202-1 (eg, Figure 2 first link 205).

[0098] In operation 410, the first device 202-1 may transmit resource control information to change at least a portion of pre-allocated resources for transmitting data packets to the user equipment 201. The first device 202-1 may transmit the resource control information before or during establishment of the first link 205.

[0099] In operation 415, the first device 202-1 may establish a second link with the second device 202-2 (eg, Figure 2 The first device 202-1 may establish the second link 215-1 with the second device 202-2 before establishing the first link 205 with the user equipment 201. The first device 202-1 and the second device 202-2 may optionally skip operation 415.

[0100] In operation 420, the first device 202-1 may send information associated with the first link 205 to the external server 203. The first device 202-1 may send information associated with the first link 205 to the external server 203 before establishing the second link 215-1 or during establishing the second link 215-1. The information associated with the first link 205 may include, for example, at least one of address information, clock information, channel information, SDP result information, information about supported functions, link key information, or an EIR packet. In another example, the information associated with the first link 205 may also include a parameter containing resource control information.

[0101] In operation 425 , the external server 203 may transmit information associated with the first link 205 to the second device 202 - 2 .

[0102] The first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message.

[0103] The first device 202 - 1 and the second device 202 - 2 may negotiate resource information for sending a response message based on resource control information included in the information associated with the first link 205 .

[0104] The first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message separately from the resource control information. For example, the first device 202-1 and the second device 202-2 may negotiate resource information for sending a response message during or after performing operation 415. In this case, the device sending the response message in the first half-time slot may be determined as a device (e.g., the first device 202-1) acting as a master device or a device (e.g., the second device 202-2) acting as a slave device (e.g., the second device 202-2). In another example, the first device 202-1 and the second device 202-2 may negotiate resource information based on a subject sending information associated with the first link 205. In this case, the device sending the response message in the first half-time slot may be determined as a device (e.g., the first device 202-1) sending information associated with the first link 205 or a device (e.g., the second device 202-2) receiving information associated with the first link 205.

[0105] According to another embodiment of the present disclosure, the external server 203 may determine resource information for sending a response message, and may send the resource information to the first device 202-1 and the second device 202-2. For example, the external server 203 may determine that a device acting as a master device (e.g., the first device 202-1) or a device acting as a slave device (e.g., the second device 202-2) sends a response message in the first half time slot. In another example, the external server 203 may negotiate resource information based on a subject that sends information associated with the first link 205. In this case, the device that sends the response message in the first half time slot may be determined as a device that sends information associated with the first link 205 (e.g., the first device 202-1) or a device that receives information associated with the first link 205 (e.g., the second device 202-2).

[0106] In operation 430 , the user device 201 may transmit a data packet including content to the first device 202 - 1 through the first link 205 .

[0107] In operation 435 , the second device 202 - 2 may receive the same data packet as that received by the first device 202 - 1 by performing shadowing based on at least a portion of information associated with the first link 205 received from the external server 203 (eg, address information or clock information).

[0108] In operation 440, the first device 202-1 may send a response message to the received data packet to the user equipment 201 through the first link 205. The first device 202-1 may send the response message of the first device 202-1 based on the second resource obtained by changing at least a part of the pre-allocated first resource to avoid conflict with the response message sent by the second device 202-2. The second resource may be changed based on resource control information sent from the first device 202-1 to the user equipment 201.

[0109] In operation 445, the second device 202-2 may send a response message to the data packet received in operation 435 to the user equipment 201 based on the information associated with the first link 205 received in operation 425. For example, the second device 202-2 may send a response message including an access code and address information corresponding to the first link 205 through a resource indicated by the resource control information (or resource information negotiated between the second device 202-2 and the first device 202-1).

[0110] Despite Figure 4 Not shown, but in response to receiving the response message indicating NACK, the user equipment 201 may directly resend the same data packet, or the first device 202-1 may relay the data packet. In this case, the user equipment 201 may request the first device 202-1 to relay the data packet.

[0111] Figure 5 is a flowchart illustrating an operation of an electronic device receiving a response message according to an embodiment of the present disclosure. Figure 5 The embodiment shown can be Figure 2 The user equipment 201 may be executed by at least one component included in the user equipment 201, by at least one component (for example, Figure 1 The processor 120 or the wireless communication module 192) is used to perform the operations in the flowchart.

[0112] refer to Figure 5 In operation 505, the electronic device may establish communication with an external electronic device (eg, Figure 2 The first device 202-1) has a link (eg, Figure 2 first link 205).

[0113] In operation 510, the electronic device may transmit a data packet including content to an external electronic device through a processor and a wireless communication circuit. The electronic device may transmit the data packet based on a first resource (eg, at least one of a time resource or a channel resource) defined in a process of establishing a link.

[0114] In operation 515, the electronic device may identify, through the processor, whether the external electronic device supports the resource control function. The electronic device may identify, based on the resource control information, whether the external electronic device supports the resource control function. The resource control information may be received from the external electronic device before, during, or after the link is established. Figures 8 to 11 Various embodiments of identifying whether an external electronic device supports a resource control function are described.

[0115] The electronic device may perform operation 515 before sending a data packet (operation 505 or operation 510). For example, the electronic device may perform operation 515 before starting to send a data packet including content. In another example, the electronic device may perform operation 515 after sending a data packet including a certain content (e.g., video) and before sending a data packet including another content (e.g., audio). In another example, when the electronic device and the external electronic device have a history of establishing a link or interconnecting with each other through the same user account or a similar user account (e.g., a family account), the electronic device may recognize that the external electronic device performs a resource control function without performing operation 515. In this case, the electronic device may perform operation 525 after operation 510.

[0116] When the external electronic device does not support the resource control function, in operation 520, the electronic device may receive a response message from the external electronic device through the pre-allocated first resource through the processor and the wireless communication circuit. In this case, even if multiple external electronic devices (e.g., Figure 2 The first device 202-1 and the second device 202-2) send multiple response messages, and the electronic device can only receive the sent response messages through the pre-allocated first resource.

[0117] When the external electronic device supports the resource control function, the electronic device can receive multiple response messages through the second resource obtained by changing at least a part of the first resource through the processor and the wireless communication circuit in operation 525. In addition to the external electronic device that establishes a link with the electronic device, multiple response messages can also be received from another external electronic device (e.g., the second device 202-2 or the third device 202-3) that supports the Bluetooth network.

[0118] When establishing a link with an external electronic device based on a Bluetooth conventional network, the electronic device may reallocate the first resource by dividing the pre-allocated first resource (e.g., time slot) according to the number of different external electronic devices. For example, when a different external electronic device is provided, the electronic device may receive a response message from the external electronic device through half (e.g., 0.3125 ms) of the pre-allocated time slot (e.g., 0.6625 ms), and may receive a response message from a different external electronic device in the remaining half of the time slot.

[0119] When establishing a link with an external electronic device based on a BLE network, the electronic device may change at least a portion of a first resource (e.g., TintV, Npeers, Tpeers, Tstartinstance, Npeersindex, or TradTimeout), which is included in the resource control information and is pre-allocated to send data packets.

[0120] Figure 6 Detailed description is a flowchart illustrating an operation of an electronic device sending a response message according to an embodiment of the present disclosure. Figure 6 The illustrated embodiment may be executed by a device (eg, the first device 202-1) to create a Figure 2 The first device 202-1 can be connected to the user equipment 201 through at least one component (for example, Figure 1 The processor 120 and the wireless communication module 192) perform operations according to the flowchart 600.

[0121] refer to Figure 6 In operation 605, the electronic device may establish a connection with a first external electronic device (eg, Figure 2 of the user equipment 201) (eg, Figure 2 first link 205).

[0122] In operation 610, the electronic device may transmit resource control information to the first external electronic device through the processor and the wireless communication circuit. The electronic device may transmit the resource control information to the first external electronic device before or when the first link is created.

[0123] The resource control information may indicate whether the electronic device can support the resource control function, or whether another second external electronic device is added. According to another embodiment, the resource control information may indicate at least one parameter for transmitting the data packet.

[0124] Whenever another second external electronic device is added, the electronic device may send resource control information to the first external electronic device. The electronic device may send resource control information to the first external electronic device in each specified period. The electronic device may send resource control information to the first external electronic device after receiving a data packet, or may send resource control information to the first external electronic device after receiving some data packets or before receiving another data packet.

[0125] In operation 615, the electronic device may establish a connection with a second external electronic device (eg, Figure 1 The second link of the second device 202-2) (eg, Figure 2 The electronic device may establish a second link with the second external electronic device while maintaining the first link. The electronic device may establish a first link with the first external electronic device after establishing the second link with the second external electronic device.

[0126] In operation 620, the electronic device may send information associated with the first link to the second external electronic device through the processor and the wireless communication circuit. The information associated with the first link may include, for example, at least one of address information, clock information, channel information, SDP result information, information about supported functions, link key information, or EIR packets. In another example, the information associated with the first link may also include parameters containing resource control information.

[0127] The electronic device may send information associated with the first link to the second external electronic device before or when the second link is created. Whenever resource control information of information associated with the first link is updated, the electronic device may send the updated information to the second external electronic device. The electronic device may send the updated information to the second external electronic device through an external server (e.g., Figure 4 The external server 203) sends information associated with the first link to the second external electronic device.

[0128] In operation 625, the electronic device may receive a data packet from the first external electronic device through the processor and the wireless communication circuit. For example, the electronic device may receive the data packet through the first link.

[0129] In operation 630, the electronic device may send a response message to the first external electronic device by changing the second resource obtained by at least a portion of the pre-allocated first resource based on the resource control information. The electronic device may send the response message through the processor and the wireless communication circuit. The electronic device may generate an access code and address information (e.g., LT address information) corresponding to the first link, and may send a response message including the generated access code and the generated address information.

[0130] Figure 7 is another flowchart illustrating an operation of an electronic device sending a response message according to an embodiment of the present disclosure. Figure 7 The embodiment shown can be created without Figure 2 The second device 202-2 may be configured to connect to the user equipment 201 through at least one component (eg, Figure 1 The processor 120 and the wireless communication module 192) perform operations according to the flowchart 700.

[0131] refer to Figure 7 In operation 705, the electronic device may establish a connection with a first external electronic device (eg, Figure 2 The second link (eg, Figure 2 of the second link 215-1).

[0132] In operation 710, the electronic device may receive a communication with the first external electronic device and the second external electronic device (eg, Figure 2 A first link (eg, Figure 2 The information associated with the first link 205) may include, for example, at least one of address information, clock information, channel information, SDP result information, information about supported functions, link key information, or an EIR packet. In another example, the information associated with the first link may also include parameters containing resource control information.

[0133] The electronic device may receive information associated with the first link from the first external electronic device before or when the second link is created. The electronic device may receive resource control information of the information associated with the first link from the first external electronic device separately from another information. The electronic device may receive resource control information of the information associated with the first link from the first external electronic device from an external device (e.g., Figure 2 The external server 203 or the third device 202-3) receives information associated with the first link.

[0134] In operation 715, the electronic device may receive a data packet based on at least a portion of the information associated with the received first link through the processor and the wireless communication circuit. For example, the electronic device may determine the hopping channel of the first link through the address information and the clock information, and monitor the determined hopping channel to receive the data packet received from the second external electronic device.

[0135] In operation 720, the electronic device may send a response message to the second external electronic device to the data packet received based on at least a portion of the information associated with the first link through the processor and the wireless communication circuit. For example, the electronic device may generate an access code corresponding to the first link, and may send a response message including the generated access code to the second external electronic device.

[0136] According to the above method, the electronic device can receive (e.g., shield) a data packet from the second external electronic device using information associated with the first link without creating a link with the second external electronic device, and can send a response message to the second external electronic device to the data packet received through the changed second resource. Because the electronic device does not create a link with the second external electronic device, the electronic device can reduce power consumption and delay time spent on creating a link.

[0137] Figures 8 to 11 Various embodiments of the present disclosure are shown in which the user equipment 201 identifies whether the first device 202-1 supports a resource control function.

[0138] Figure 8 A graph illustrating a query process according to an embodiment of the present disclosure is shown.

[0139] refer to Figure 8 , the user equipment 201 and the first device 202-1 may perform an inquiry process based on a Bluetooth legacy standard (eg, Institute of Electrical and Electronics Engineers (IEEE) 802.xx (xx is a natural number)) to discover a paired device to establish a first link (eg, Figure 2 first link 205).

[0140] The horizontal axis of the graph 800 may indicate time (unit: μs). In the graph 800, the first time slot 811 may indicate an interval at which the user equipment 201 transmits data, and the second time slot 812 may indicate an interval at which the first device 202-1 transmits data. According to an embodiment, the first time slot 811 and the second time slot 812 may include a specified interval (e.g., 625 μs).

[0141] The user equipment 201 may transmit an identification (ID) packet in at least a certain interval of the first time slot 811. The ID packet may include, for example, a device access code (DAC) or an inquiry access code (IAC) of the user equipment 201. According to an embodiment, the ID packet may be transmitted at a specified interval (e.g., 68 μs).

[0142] The first device 202-1 may activate wireless communication circuitry (e.g., Figure 1The first device 202-1 may establish a link with the user equipment 201 and perform monitoring of the first time slot 811 to receive the ID packet. In response to receiving the ID packet, the first device 202-1 may send a frequency hopping synchronization (FHS) packet to the user equipment 201 in at least a certain interval of the second time slot 812. The FHS packet may include control information (e.g., clock information or address information) for establishing the first link 205.

[0143] After sending the FHS packet, the first device 202-1 sends an extended query response (EIR) packet to the user equipment 201 in at least one interval of the next second time slot 812. The EIR packet may include resource control information. For example, the EIR packet may indicate whether the first device 202-1 can support the resource control function with 1 bit. The user equipment 201 can identify that the first device 202-1 can support the resource control function through the EIR packet.

[0144] Fig. 9 The data format of the EIR packet according to the embodiment of the present disclosure is shown. Some data formats of the EIR packet can be based on the Bluetooth legacy standard specification.

[0145] refer to Fig. 9 , EIR packet 900 may include a first part 901 and a second part 902. First part 901 may include a sequence of data structures (e.g., EIR data structure 1, EIR data structure 2, ..., and EIR data structure N; N is a natural number). The data structure may include a length field 911 indicating a length value of the data and a data field 912. Data field 912 may include an EIR data type field 914 indicating a type of EIR data and an EIR data field 916. First device 202-1 may insert resource control information into EIR data field 916.

[0146] Fig.10 1000 is a signal flow diagram of sharing feature information according to an embodiment of the present disclosure.

[0147] refer to Fig.10 Operations 1005 to 1010 may be performed upon establishing a first link (eg, Figure 2 The process of the first link 205) is performed. Fig.10 An embodiment is shown in which the user device 201 requests feature information. However, according to various embodiments, the first device 202-1 may request feature information.

[0148] In operation 1005, the user equipment 201 may send a request message for requesting feature information to the first device 202-1. The request message may include, for example, a Link Manager Protocol (LMP)_features_req message based on the Bluetooth legacy standard or the BLE standard.

[0149] In operation 1010, the first device 202-1 may send a response message including feature information of the first device 202-1 in response to the request message. The response message may include, for example, an LMP_features_res message based on the Bluetooth legacy standard or the BLE standard. The first device 202-1 may insert the resource control information into the response message. The user equipment 201 may recognize that the first device 202-1 supports the resource control function through the response message.

[0150] Fig.11 A flowchart of a negotiation process according to an embodiment of the present disclosure is shown.

[0151] refer to Fig.11 , the user equipment 201 and the first device 202-1 may establish a first link in operation 1105 (eg, Figure 2 After establishing the first link 205 of the BLE protocol and before sending data packets (e.g., operations 1115-1, 1115-2, ...), a negotiation process is performed based on the BLE standard in operation 1110. For example, whenever a link is established with another device (e.g., the second device 202-2) (e.g., Figure 2 When the second link 215-1 is established, the first device 202-1 may send a request for negotiation to the user equipment 201.

[0152] In the negotiation process (operation 1110), the user device 201 and the first device 202-1 may negotiate at least one parameter for sending data packets. The at least one parameter may include, for example, TintV, Npeers, Tpeers, Tstartinstance, NpeersIndex, or TrdaTimeout. For example, when N (N is a natural number) devices are added in addition to the first device 202-1, the number of times the user device 201 receives a response message increases by N, so the maximum amount of data sent by each device may be reduced inversely proportional to N.

[0153] The user equipment 201 can be Figures 8 to 11 The method shown is to identify whether the first device 202-1 can support the resource control function.

[0154] For example, after creating the first link 205, the user equipment 201 may identify whether the first device 202-1 supports the resource control function by sharing resource control information about the logical link control and adaptation layer protocol (L2CAP) layer based on the Bluetooth standard.

[0155] In another example, the user equipment 201 may share resource control information via a network other than a Bluetooth network (eg, cellular, WiFi, WiFi Direct, IrDA, or Ultra Wideband (UWB)).

[0156] In another example, the user device 201 may receive a user input for requesting to perform a resource control function (or requesting to add another device).

[0157] In another example, the first device 202 - 1 can send the resource control information through an advertisement.

[0158] In another example, when the device name of the first device 202 - 1 is a pre-designated device name, the user equipment 201 may determine that the first device 202 - 1 performs a resource control function.

[0159] In another example, when the manufacturer of the user equipment 201 is the same as the manufacturer of the first device 202 - 1 , the user equipment 201 may determine that the first device 202 - 1 performs the resource control function.

[0160] FIG. 12A to FIG. 12C and FIG. 13A to FIG. 13C An embodiment of controlling resources for transmitting data packets based on resource control information according to various embodiments of the present disclosure is shown.

[0161] FIG. 12A to FIG. 12C An example of associated time resources in a Bluetooth legacy network according to various embodiments of the present disclosure is shown.

[0162] Fig. 12A An embodiment is shown in which the user equipment 201 receives response messages indicating ACK from the first device 202-1 and the second device 202-2. Fig. 12B An embodiment is shown in which the user equipment 201 receives a response message indicating NACK from the first device 202-1. Fig. 12C An embodiment is shown in which the user equipment 201 does not receive a response message from the first device 202-1.

[0163] refer to FIG. 12A to FIG. 12C, the horizontal axis of the graphs 1201, 1202, and 1203 indicates time. The user equipment 201 may send a data packet including content (e.g., data 1) in the first interval 1211, and may receive a response message after the first interval 1211 and before an interval (e.g., the sum of the second interval 1212 and the third interval 1213) for sending the next data packet (e.g., data 2). For example, the interval (e.g., the second interval 1212 and the third interval 1213) for receiving the response message based on the Bluetooth traditional standard may correspond to one time slot (e.g., 625ms). Based on the response messages received in the second interval 1212 and the third interval 1213, the user equipment 201 may retransmit the data packet in the fourth interval 1214 or send the next data packet.

[0164] When it is identified that the first device 202-1 supports the resource control function, the user equipment 201 can divide the interval for receiving the response message according to the number of devices receiving the data packet, thereby changing the time resource. For example, when there are two devices receiving the data packet, such as FIG. 12A to FIG. 12C As shown, the user equipment 201 can receive a first response message from the first device 202-1 within a second interval 1212 corresponding to half of the time slot (e.g., 0.3125ms), and can receive a second response message from the second device 202-2 within a third interval 1213 corresponding to the remaining half. FIG. 12A to FIG. 12C An embodiment is shown in which the first device 202-1 sends a response message within the second interval 1212. However, according to another embodiment, the second device 202-2 may send a response message within the second interval 1212, and the first device 202-1 may send a response message within the third interval 1213.

[0165] The user equipment 201 may send the next data packet (eg, data 2) after the reception of the plurality of response messages indicating ACK is completed. Fig. 12A , when the first response message indicating ACK is received within the second interval 1212 and the second response message indicating ACK is received within the third interval 1213, the user equipment 201 may send the next data packet.

[0166] In another example, when Fig. 12B When receiving at least one response message (eg, the first response message) indicating NACK among the multiple response messages, the user equipment 201 may resend the same data packet (eg, data 1). Fig. 12CAs shown, when at least one response message (e.g., a first response message) among multiple response messages is lost or the first device 202-1 fails to send a response message due to a failure to receive a data packet (e.g., Data 1), the user device 201 can resend the same data packet (e.g., Data 1).

[0167] When the size of the first response message sent from the first device 202-1 is larger than the size of the second interval 1212, the second device 202-2 may not send the second response message. In this case, the user equipment 201 may resend the same data packet (e.g., data 1) or may resend the next data packet (e.g., data 2).

[0168] Based on the limitation of physical distance or communication volume, the reception of the response message indicating ACK may not be completed. In order to prevent the delay time from increasing as the data packets are continuously retransmitted, the user equipment 201 can set a timer, and even if the reception of the response message indicating ACK is not completed when the set time expires, the next data packet (e.g., data 2) can be sent.

[0169] The first device 202-1 or the second device 202-2 may request the user equipment 201 to disable the resource control function based on a specified condition. For example, when the second link 215-1 between the first device 202-1 and the second device 202-2 is released, the reception state of the data packet is less than a threshold, or the communication state of the first link 205 is less than a threshold, the first device 202-1 or the second device 202-2 may request to disable the resource control function. When receiving the request to disable the resource control function, the user equipment 201 may not divide the interval for receiving the response message.

[0170] When the second link 215-1 between the first device 202-1 and the second device 202-2 is released, the first device 202-1 or the second device 202-2 may send a response message multiple times instead of requesting to disable the resource control function. For example, the first device 202-1 may send a response message within the second interval 1212 and may send a response message within the third interval 1213.

[0171] FIG. 13A to FIG. 13C Examples of parameters for sending data packets in a BLE network according to various embodiments of the present disclosure are shown. FIG. 13A to FIG. 13B shows the parameters used to send a data packet, and Fig. 13C The operation of sending data packets based on these parameters is shown.

[0172] refer to FIG. 13A to FIG. 13C, the horizontal axes of the graphs 1301, 1302, and 1303 indicate time. The user equipment 201 and the devices 202-1 and 202-2 may transmit data packets of a specified size and a specified number based on instances, intervals, and sequences according to parameters defined in the BLE standard.

[0173] refer to Fig.13A , TintV may indicate an interval at which the user device 201 may send a data packet at least once. For example, the user device 201 may send a data packet in each interval indicated by TintV. Multiple devices 202-1 and 202-2 may receive the data packet of "TintV" and may send a response message in response to receiving the data packet. "Npeers" may indicate the number of devices (e.g., two) that receive data packets from the user device 201. "Tpeers" may indicate the maximum amount of data (e.g., response message) (or maximum time) sent by each of the multiple devices 202-1 and 202-2. "NpeersIndex" may indicate the sequence in which the multiple devices 202-1 and 202-2 send response messages. For example, when the value of "NpeersIndex" of the first device 202-1 is 1 and the value of "NpeersIndex" of the second device 202-2 is 2, the first device 202-1 may send a response message first. "TrdaTimeout" may indicate the interval or frequency at which the first device 202-1 sends the same data packet. For example, when data packet 2 is transmitted and a response message indicating "NACK" is received from the first device 202-1 or the second device 202-2, the user device 201 may retransmit data packet 2. In this case, when the interval or frequency indicated by "TrdaTimeout" expires after data packet 2 is retransmitted, the user device 201 may transmit the next data packet (e.g., data packet 3) without transmitting data packet 2 even if a response message indicating "NACK" is received from the first device 202-1.

[0174] refer to Fig. 13B , “Tstartinstance” may indicate a time point or instance at which the added device (e.g., the second device 202-2) may send a data packet. For example, when the second device 202-2 is added after the user device 201 sends a specific data packet (e.g., data packet 1, 2, 3, or 4), the user device 201 and the first device 202-1 may send a data packet through a negotiation process (e.g., Fig.11The negotiation process 1110 of the first device 202-1 determines the time point indicated by "Tstartinstance" (for example, the time point at which the data packet 5 is sent). The first device 202-1 may send the "Tstartinstance" included in the information associated with the first link 205 to the second device 202-2. The second device 202-2 may send response data to the data sent by the user equipment 201 to the first device 202-1 from the time point indicated by "Tstartinstance".

[0175] refer to Fig. 13C , when receiving data packet 1 from user equipment 201, first device 202-1 and second device 202-2 may send a response message indicating "ACK". When the value indicated by "Npeers" is 2 and when two response messages are received, user equipment 201 may send data packet 2 within the next interval of "TintV".

[0176] When at least one of the multiple response messages indicates "NACK", the user equipment 201 can retransmit the same data packet within the interval indicated by "TintV". The user equipment 201 can determine whether to retransmit the data packet based on the response message corresponding to the sequence (or time point) indicated by "NpeersIndex".

[0177] For example, when the "NpeersIndex" of the first device 202-1 is 1 and the "NpeersIndex" of the second device 202-2 is 2 and when the user device 201 receives a response message indicating "NACK" in a sequence (or time point) in which NpeersIndex indicates "2", the user device 201 may retransmit the data packet. In this case, when the first device 202-1 receives the retransmitted data packet, the first device 202-1 may ignore the retransmitted data packet.

[0178] In another example, when the user equipment 201 receives a response message indicating "NACK" at a time point where "NpeersIndex" indicates 1 and indicates 2, the user equipment 201 may retransmit the data packet. In this case, the first device 202-1 and the second device 202-2 may send a response message for the data packet retransmitted based on the sequence indicated by "NpeersIndex".

[0179] The user equipment 201 may resend the data packet until the time (or number of times) indicated by "TrdaTimeout" has passed.

[0180] As mentioned above, electronic devices (e.g. Figure 2The user equipment 201 may include wireless communication circuitry supporting a Bluetooth network (eg, Figure 1 at least a portion of the wireless communication module 192 of the present invention), at least one processor operably connected to the wireless communication circuit (e.g., Figure 1 processor 120) and a memory operatively connected to at least one processor (e.g., Figure 1 The memory 130 may include instructions that, when executed, cause at least one processor to: establish a connection with an external electronic device (e.g., Figure 2 The first device 202-1) has a link (eg, Figure 2 a first link 205); sending a data packet including content to an external electronic device through a wireless communication circuit; identifying whether the external electronic device supports a resource control function; when the external electronic device does not support the resource control function, receiving at least one response message to the data packet through a pre-allocated first time resource; and when the external electronic device supports the resource control function, receiving multiple response messages to the data packet through a second time resource obtained by changing at least a portion of the first time resource.
