Description

Electronic device providing distance-based service and operation method thereof

Various embodiments of the present disclosure relate to an electronic device providing a distance-based service (DBS) and an operating method thereof.

Recently, with the development of information communication technology, various wireless communication methods and various services are being developed. In particular, the ultra wide band (UWB) method is a communication method capable of transmitting and receiving signals using very short pulses (eg, several nanoseconds) with low power over a wide band. In the past, the UWB method was used for military purposes such as military radar and remote sensing, but since the US Federal Communications Commission (FCC) permitted commercial use of UWB by limiting it to the field of indoor wireless communication, the UWB method has been used in various fields.

The UWB method is drawing attention as a method capable of recognizing and tracking the precise location of an electronic device in an Internet of Things (IoT) environment or a ubiquitous environment in the future. The UWB method can be used in various fields such as indoor and outdoor location tracking, indoor navigation, asset tracking, disaster-related industrial robots, home and building automation, vehicle and home smart key services, or unmanned payment systems.

As the UWB method is used, a distance between electronic devices can be accurately measured with an error within several cm. As relatively precise distance measurement becomes possible according to the UWB method, demand for a distance-based service (DBS) as well as a location-based service (LBS) is increasing.

A location-based service is a location-based service that provides information based on a network installed in a specific location. In order to provide a location-based service, it is necessary to build an infrastructure suitable for the location-based service.

The distance-based service is a service based on distance and may be based on real-time precision distance measurement. Representative examples of distance-based services include a lost & found service and a smart car key service.

In the case of a lost and found service, as a service for tracking the location of a target electronic device, it is performed between a plurality of electronic devices including registered target electronic devices, and is a non-real time service. In order to provide a lost and found service, it is necessary to build a map and infrastructure for registering/tracking the location of a target electronic device.

The smart car key service is a 1:1 service performed between a vehicle electronic device built into a vehicle and a driver electronic device owned by a driver, and may be provided only between registered electronic devices (eg, a vehicle electronic device and a driver electronic device). Since the distance-based service is performed only between registered electronic devices, electronic devices related to the distance-based service must perform a registration procedure related to the distance-based service in advance. This registration process may limit the expansion of distance-based services.

Various embodiments of the present disclosure may provide an electronic device providing a distance-based service and an operating method thereof.

Various embodiments of the present disclosure may provide an electronic device that provides a distance-based service based on real-time distance measurement and an operating method thereof.

Various embodiments of the present disclosure may provide an electronic device that provides a distance-based service based on a multi-object ranging scheme and an operating method thereof.

According to various embodiments of the present disclosure, an electronic device includes a communication circuit and at least one processor operatively connected to the communication circuit, wherein the at least one processor: selects a role of the electronic device as a tag initiating a distance-based service, selects at least one external electronic device to perform a distance measurement operation with the electronic device based on confirmation that a condition for initiating the distance-based service is satisfied, and sends a first message including information related to the distance-based service through the communication circuit transmitting, receiving a second message in response to the first message from the at least one external electronic device through the communication circuit, and based on receiving the second message from the at least one external electronic device, performing a ranging operation with the at least one external electronic device through the communication circuit to estimate a distance between the electronic device and the at least one external electronic device.

The communication module 190 may support establishment of a direct (e.g., wired) communication channel or wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108), and communication through the established communication channel. The communication module 190 may include one or more communication processors that operate independently of the processor 120 (eg, an application processor) and support direct (eg, wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (eg, 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 (eg, a local area network (LAN) communication module or a power line communication module). A corresponding communication module among these communication modules may communicate with the external electronic device 104 through a first network 198 (eg, a short-range communication network such as Bluetooth, wireless fidelity (Wi-Fi) direct, or an infrared data association (IrDA)) or a second network 199 (eg, a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a long-distance communication network such as a computer network (eg, LAN or WAN)). These various types of communication modules may be integrated as one component (eg, a single chip) or implemented as a plurality of separate components (eg, multiple chips). The wireless communication module 192 may identify or authenticate the electronic device 101 within a communication network such as the first network 198 or the second network 199 using subscriber information (eg, International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network after a 4G network and a next-generation communication technology, for example, NR access technology (new radio access technology). NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), minimization of terminal power and access to multiple terminals (massive machine type communications (mMTC)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module 192 may support a high frequency band (eg, mmWave band) to achieve a high data rate, for example.

In connection with the description of the drawings, like reference numbers may be used for like or related elements. The singular form of a noun corresponding to an item may include one item or a plurality of items, unless the relevant context clearly dictates otherwise. In this document, each of the 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 of the items listed together in the corresponding phrase, or all possible combinations thereof. Terms such as "first", "second", or "first" or "secondary" may be used simply to distinguish a corresponding component from other corresponding components, and do not limit the corresponding components in other respects (e.g., importance or order). When a (e.g., a first) component is referred to as “coupled” or “connected” to another (e.g., a second) component, with or without the terms “functionally” or “communicatively,” it means that the component may be connected to the other component directly (e.g., by wire), wirelessly, or through a third component.

The term "module" used in various embodiments of this document may include units implemented in hardware, software, or firmware, and may be used interchangeably with terms such as, for example, logic, logical blocks, parts, or circuits. A module may be an integrally constituted part or a minimum unit or part of the above parts that performs one or two or more functions. For example, according to one embodiment, the module may be implemented in the form of an application-specific integrated circuit (ASIC).

Various embodiments of this document may be implemented as software (eg, program 140) including one or more instructions stored in a storage medium (eg, internal memory 136 or external memory 138) readable by a machine (eg, electronic device 101). For example, a processor (eg, the processor 120 ) of a device (eg, the electronic device 101 ) may call at least one command among one or more instructions stored from a storage medium and execute it. This enables the device to be operated to perform at least one function according to the at least one command invoked. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The device-readable storage medium may be provided in the form of a non-transitory storage medium.

According to one embodiment, the method according to various embodiments disclosed in this document may be included and provided in a computer program product. Computer program products may be traded between sellers and buyers as commodities. A computer program product may be distributed in the form of a device-readable storage medium (eg, compact disc read only memory (CD-ROM)), or may be distributed (eg, downloaded or uploaded) online, through an application store (eg, Play Store ^TM ) or directly between two user devices (eg, smartphones). In the case of online distribution, at least part of the computer program product may be temporarily stored or temporarily created in a device-readable storage medium such as a manufacturer's server, an application store server, or a relay server's memory.

According to various embodiments, each component (eg, module or program) of the above-described components may include a single object or a plurality of objects, and some of the multiple objects may be separately disposed in other components. According to various embodiments, one or more components or operations among the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (eg modules or programs) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by a corresponding component of the plurality of components prior to the integration. According to various embodiments, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, may be omitted, or one or more other operations may be added.

Various embodiments may provide an electronic device that provides a distance-based service (DBS) in a wireless communication network and an operating method thereof. In one embodiment, the distance-based service may be based on real-time distance measurement based on a UWB method and may not require a separate pairing procedure. Since the distance-based service according to an embodiment does not require a separate pairing procedure, it may be referred to as an anonymous distance-based service. A distance-based service according to an embodiment may be performed between a plurality of unspecified electronic devices, and thus may be based on a multi-object ranging scheme. The multi-object ranging method may not be a one-to-one UWB ranging method in which two electronic devices that have performed a pairing procedure transmit and receive a UWB ranging request message and a UWB ranging response message, but a many-to-many UWB ranging method in which a plurality of electronic devices that have not performed a pairing procedure transmit and receive UWB ranging request messages and UWB ranging response messages.

Characteristics of services based on the UWB scheme may be as shown in Table 1 below. Services based on the UWB scheme may include an unspecified distance based service, an identified distance based service (identified DBS), an unspecified location based service (LBS), and a specific location based service.

<Table 1>

As shown in Table 1, services based on the UWB scheme may be classified into unspecified distance-based services, specific distance-based services, unspecified location-based services, and specific location-based services according to their characteristics.

First, an unspecified distance-based service will be described.

A typical application of the unspecified distance-based service may include a pedestrian safety service. In the case of an unspecified distance-based service, service pairing (eg, a pairing procedure) is not required, and thus may have an unspecified (or unplanned) characteristic in terms of service pairing. Since service pairing is not required in the case of an unspecified distance based service, UWB roles of electronic devices participating in the unspecified distance based service may not be fixed. Since UWB roles of electronic devices participating in the unspecified distance-based service may not be fixed, electronic devices participating in the unspecified distance-based service may not know each other's UWB roles. A non-specific distance-based service may support a many-to-many relationship, such that multiple electronic devices may form relationships with multiple other electronic devices. Since the many-to-many relationship is supported in the unspecified distance based service, electronic devices participating in the unspecified distance based service can be dynamically changed. Since a large number of electronic devices participate in an unspecified distance-based service, faster real-time distance measurement may be required. In an unspecified distance-based service, a ranging cycle unit may be millisecond (msec).

Second, a specific distance-based service is described as follows.

Representative applications of a specific distance-based service may include a smart car key service and/or a lost & found service. In the case of a specific distance-based service, service pairing is required, and thus may have a planned characteristic in terms of service pairing. Since service pairing is required in the case of a specific distance-based service, UWB roles of electronic devices participating in the specific distance-based service may be fixed. Since UWB roles of electronic devices participating in a specific distance-based service may be fixed, electronic devices participating in a specific distance-based service may know each other's UWB roles. A specific distance-based service may support a one-to-one relationship, and thus two electronic devices may form a one-to-one relationship. In a specific distance-based service, a ranging cycle unit may be several seconds (supra-sec).

Thirdly, an unspecified location-based service will be described as follows.

Representative applications of unspecified location-based services may include indoor positioning services. In the case of unspecified location-based services, service pairing is not required, and thus may have unspecified (or unplanned) characteristics in terms of service pairing. Since service pairing is not required in the case of an unspecified location based service, UWB roles of electronic devices participating in the unspecified location based service may not be fixed. Since UWB roles of electronic devices participating in the unspecified location based service may not be fixed, electronic devices participating in the unspecified location based service may not know each other's UWB roles. The non-specific location-based service may support a one-to-many relationship, and thus, one electronic device and a plurality of electronic devices may form a one-to-many relationship. In an unspecified location-based service, a ranging cycle unit may be several seconds.

Fourth, a specific location-based service is described as follows.

Representative applications of specific location-based services may include home Internet of Things (IoT) services. In the case of a specific location-based service, service pairing is required, so it may have a planning characteristic in terms of service pairing. Since service pairing is required in the case of a specific location-based service, UWB roles of electronic devices participating in a specific location-based service may be fixed. Since UWB roles of electronic devices participating in a specific location-based service may not be fixed, electronic devices participating in a specific location-based service may know each other's UWB roles. Certain location-based services may support a one-to-many relationship, and thus one electronic device and multiple electronic devices may form a one-to-many relationship. In a specific location-based service, a ranging cycle unit may be several seconds.

A distance-based service proposed in various embodiments of the present disclosure may be an unspecified distance-based service. As described in Table 1, the unspecified distance-based service may be based on a real-time UWB measurement operation (eg, a real-time distance measurement operation) between a plurality of unspecified electronic devices.

Various embodiments of the present disclosure can provide an electronic device that can support a real-time distance measurement operation between a plurality of unspecified electronic devices, can guarantee service quality while a plurality of unspecified electronic devices participate, can easily apply and expand a service because a separate infrastructure is not required, and provide a distance-based service that enables immediate participation because a pairing procedure is not required, and an operating method thereof.

In an embodiment, the external electronic device 220 may also estimate the distance between the external electronic device 220 and the electronic device 101 based on the UWB method.

As the Bluetooth pairing procedure is performed between the vehicular electronic device 500 and the electronic device 101, the vehicular electronic device 500 and the electronic device 101 may share a mutual recognition key defined in the Bluetooth standard (eg, a Bluetooth identity resolving key (IRK)). In one embodiment, the Bluetooth IRK may be a key shared through a Bluetooth pairing procedure between two electronic devices. Since FIG. 6 assumes that the vehicular electronic device 500 and the electronic device 101 work together to provide a distance-based service, a Bluetooth pairing procedure is performed between the vehicular electronic device 500 and the electronic device 101 in operation 613. However, when the electronic device 101 independently provides a distance-based service without the vehicular electronic device 500, the Bluetooth pairing procedure in operation 613 may be omitted.

After the Bluetooth pairing procedure is performed between the vehicular electronic device 500 and the electronic device 101, the electronic device 101 may initialize a distance-based service in operation 615. In an embodiment, the electronic device 101 may initialize a distance-based service as a tag. The external electronic device 101 may initialize a distance based service in operation 617 . In an embodiment, the external electronic device 101 may initialize a distance-based service as a node.

According to an embodiment, in an unspecified distance-based service, a UWB device may support multiple UWB roles, and the UWB role of the corresponding UWB device may be variable. Therefore, a method of reducing (eg, minimizing) power consumption and selecting a service-friendly UWB role may be required. An embodiment may provide a method for selecting a UWB role in a distance-based service, and a method for selecting a UWB role will be described below.

In the method of selecting a UWB role according to an embodiment, the time point at which the UWB role is selected may include one of the following points of time.

(1) Manufacturing point of UWB device (fixed point)

(2) When the UWB device is powered on

(3) When distance-based service is initialized

For example, a time point at which the distance-based service is initialized may include a time point at which an application corresponding to the distance-based service is started.

(4) When distance-based service ends

For example, the point in time when the distance-based service ends may include a point in time when the UWB device leaves the vehicle. A point in time when the UWB device leaves the vehicle may include a point in time when a driver who owns the UWB device gets out of the vehicle.

(5) When the UWB device performs a pairing procedure (eg Bluetooth pairing procedure) with another UWB device

For example, when a UWB device owned by a driver enters a vehicle, a pairing procedure with the UWB device built into the vehicle may be performed, and the time point at which the pairing procedure is performed may be the time point at which the UWB role is selected.

(6) Algorithm-based viewpoint

For example, the time point based on the algorithm may include a time point when a trigger value set in the algorithm is satisfied. In one embodiment, the trigger value may be set variably as needed.

In a method for selecting a UWB role according to an embodiment, the UWB role may be selected as one of the following UWB roles.

(1) UWB roles can be selected (fixed roles) to suit distance-based services when manufacturing UWB devices.

(2) A UWB role may be selected corresponding to UWB role information provided by another UWB device.

For example, when a UWB device performs a pairing procedure with another UWB device, a UWB role of the UWB device may be selected corresponding to UWB role information provided from the other UWB device.

For another example, a UWB role of a UWB device may be selected corresponding to UWB role information broadcast in a service area (eg, a distance-based service area).

(3) A UWB role of a UWB device may be selected corresponding to a device type of a UWB device for which a pairing procedure is performed.

For example, if the distance-based service is a child collision risk notification service that informs of a risk of collision between a vehicle and a child in a child protection area, and another UWB device for which a UWB device performs a pairing procedure is the vehicular electronic device 500 or the electronic device 101, the UWB role of the UWB device may be selected as a node.

For another example, if the distance-based service is a child collision risk notification service and the other UWB device for which the UWB device performs a pairing procedure is another external electronic device associated with the external electronic device 220 (eg, a parent's smart phone and/or a wearable device), the UWB role of the UWB device may be selected as a tag.

(4) A UWB role of a UWB device may be selected based on an algorithm.

For example, when the value of a variable monitored by the UWB device exceeds a threshold value, the role of the UWB device may be selected as the set UWB role. In one embodiment, the variable and/or threshold may be variably set as needed.

For another example, the UWB device may monitor the surrounding environment of the UWB device and select a UWB role suitable for the monitored surrounding environment.

If the distance-based service is always executed in the electronic device 101 or the external electronic device 220, a relatively large amount of power may be consumed unnecessarily. The reason for this is that since the ranging cycle unit of the distance-based service is msec, the UWB measurement operation is performed in msec cycles, and thus power due to the UWB measurement operation may be consumed even when the actual distance-based service does not need to be provided.

In order to prevent such unnecessary power consumption, the electronic device 101, which is a tagged UWB device, may check whether a set first condition (eg, a distance-based service starting condition) is satisfied in operation 619. When the first condition is satisfied, the electronic device 101 may initiate a distance-based service. The first condition according to an embodiment may be a condition for starting a distance-based service, and may include a condition that the electronic device 101 exists in a service area (eg, a distance-based service area) and that the electronic device 101 is moving. For example, even if the electronic device 101 exists in the service area, starting the distance-based service when the vehicle in which the vehicular electronic device 500 is installed is not driving may cause unnecessary power consumption. Therefore, the first condition for starting the distance-based service may include a condition that the electronic device 101 exists in the service area and the electronic device 101 is moving. In an embodiment, the electronic device 101 can confirm existence in the service area based on a message received from a separate electronic device installed in the service area or information related to a service area set in a distance-based service. In an embodiment, the electronic device 101 can confirm existence in the service area based on GPS information of the electronic device 101 and information related to the service area. For example, if the verified GPS information corresponds to the service area, the electronic device 101 can confirm that the electronic device 101 exists in the service area.

Since it is assumed in FIG. 6 that the street-based service is a pedestrian safety service, the first condition includes a condition that the electronic device 101 exists in a service area and the electronic device 101 is moving. However, if the street-based service is a service other than the pedestrian safety service, the first condition may be changed to suit the corresponding service.

When it is confirmed in operation 619 that the first condition is satisfied, the electronic device 101 may select at least one target node UWB device to perform a UWB measurement operation based on a second condition (eg, a UWB measurement operation start condition) set in operation 620. Although FIG. 6 illustrates a case in which one node UWB device (eg, the external electronic device 220) exists for convenience of description, a plurality of node UWB devices for distance-based services may exist. Accordingly, the electronic device 101 may select at least one target node UWB to perform a UWB measurement operation with the electronic device 101 based on the second condition.

In an embodiment, the second condition may be a condition for starting a UWB measurement operation, and may also be a condition for selecting a target node UWB device to perform a UWB measurement operation. The second condition is explained as follows.

In one embodiment, when a plurality of unspecified UWB devices perform communication using UWB broadcast messages, an issue may occur in which some unspecified UWB devices monopolize UWB measurement opportunities. In an embodiment, an anti-monopoly scheme may be provided to address the issue that some unspecified UWB devices monopolize UWB measurement opportunities. The antitrust scheme may include a scheme in which a responder UWB device selectively responds to UWB broadcast messages transmitted from a requester UWB device. For example, in the antitrust scheme, the responder UWB device may transmit UWB response messages for only some UWB broadcast messages (e.g., one UWB broadcast message) rather than for all UWB broadcast messages transmitted from the initiator UWB device.

According to an embodiment, a broadcast address pool may be operated in an antitrust scheme. A broadcast address pool may contain two or more broadcast addresses. In an antitrust scheme, all UWB devices may use a common pool of broadcast addresses.

In an embodiment, a requester UWB device (eg, a tagged UWB device) may transmit a UWB broadcast message for only one broadcast address per unit time period. The requester UWB device may sequentially select only one broadcast address for each unit time interval from all broadcast addresses included in the broadcast address pool, and transmit a UWB broadcast message including the selected broadcast address.

In one embodiment, a responder UWB device (eg, a node UWB device) may respond only to one configured broadcast address. For example, the responder UWB device may transmit a UWB response message only for a UWB broadcast message including a broadcast address set in the responder UWB device among UWB broadcast messages transmitted from the requestor UWB device. Since the monopoly prevention method will be described with reference to FIGS. 9 and 10 below, a detailed description thereof will be omitted.

In the case of a UWB measurement method based on the UWB method, it may be difficult to increase the number of UWB devices capable of participating in real-time distance measurement. The UWB scheme may be based on an Aloha scheme in which each UWB device transmits a packet when necessary in the same radio channel and waits for an acknowledgment (ACK) packet for the transmitted packet. In the case of the UWB scheme based on the Aloha scheme, when the number of UWB devices participating in communication on the same radio channel increases, the probability of collision or a high received signal strength (e.g., the UWB device) may increase the probability that the target UWB device monopolizes the radio channel. When a collision occurs, time for resolving the collision may occur, and the time for resolving the collision may make real-time distance measurement for a plurality of UWB devices difficult. In the case of a UWB ranging protocol in the UWB scheme, since two UWB devices must transmit/receive a UWB ranging request message and a UWB ranging response message, the number of UWB devices capable of participating in real-time distance measurement per unit time period may be limited. In order to solve the collision issue, the channel monopoly issue, and/or the issue of limiting the number of UWB devices that can participate in real-time distance measurement per unit time interval in the distance measurement method based on the UWB method, a UWB multi-object ranging method may be proposed.

In the UWB multi-object ranging method according to an embodiment, a tracking zone management method may be used to reduce (e.g., minimize) the probability of collision between UWB devices participating in communication on the same radio channel and to perform real-time distance measurement. Since a tracking zone management method according to an embodiment will be described with reference to FIG. 11 below, a detailed description thereof will be omitted. In the UWB multi-object ranging method according to an embodiment, an indirect ranging method may be used to increase (eg, maximize) the number of UWB devices participating in communication per unit time on the same radio channel. Since an indirect ranging method according to an embodiment will be described with reference to FIG. 12, a detailed description thereof will be omitted here.

The electronic device 101 that selects the target node UWB device to perform the UWB measurement operation based on the second condition may initiate the UWB measurement operation, and FIG. 6 shows the case where the external electronic device 220 is selected as the target node UWB device to perform the UWB measurement operation based on the second condition.

The electronic device 101 may transmit (eg, broadcast) a UWB broadcast message based on a set period (eg, periodically) in operations 621-1 to 621-N. Since the distance-based service according to an embodiment is provided for unspecified targets (a plurality of unspecified UWB devices), the UWB broadcast message may include information related to the distance-based service, and among a plurality of unspecified UWB devices receiving the UWB broadcast message, only unspecified UWB devices related to the distance-based service may perform an operation related to the distance-based service. In one embodiment, information related to the distance-based service may include a service code indicating the distance-based service. As an example, the UWB broadcast message may be implemented as a frame specified in the IEEE 802.15.4/4z standard, and the format of the UWB broadcast message will be described with reference to FIG. 7 below, so a detailed description thereof will be omitted.

While the electronic device 101 transmits UWB broadcast messages in operations 621-1 to 621-N based on the set period, the external electronic device 220 may confirm that the first condition is satisfied in operation 623. The first condition and the operation of confirming that the first condition is satisfied may be implemented in a similar or substantially identical manner to that described in operation 619, and thus a detailed description thereof will be omitted.

After confirming that the first condition is satisfied, the external electronic device 220 may receive the UWB broadcast messages transmitted by the electronic device 101 in operations 621-1 to 621-N based on the set period, determine whether information (eg, service code) related to the distance-based service included in the received UWB broadcast messages is the same as information related to the distance-based service initiated by the external electronic device 220, and the received UWB broadcast messages. It may be checked whether the included broadcast addresses are the same as broadcast addresses set in the external electronic device 220 . When the information related to the distance service included in the received UWB broadcast messages is the same as the information related to the distance-based service initiated by the external electronic device 220, and the broadcast addresses included in the received UWB broadcast messages are the same as broadcast addresses set in the external electronic device 220, the external electronic device 220 may transmit a UWB response message, which is a response message to the received UWB broadcast messages, in operation 625.

According to an embodiment, based on an antitrust method, the external electronic device 220 receives a UWB response only to the first received UWB broadcast message among the corresponding UWB broadcast messages, even though the external electronic device 220 receives a plurality of UWB broadcast messages including information related to the same service as information related to the distance-based service initiated by the external electronic device 220 and including a broadcast address identical to that set in the external electronic device 220. message can be sent. In one embodiment, the UWB response message may be implemented as a frame specified in the IEEE 802.15.4/4z standard, and the format of the UWB response message will be described with reference to FIG. 8 below, so a detailed description thereof will be omitted here.

The external electronic device 220 that has transmitted the UWB response message may register the broadcast address of the tagged UWB device (eg, the electronic device 101) included in the UWB broadcast message in operation 627 . After registering the broadcast address, the external electronic device 220 may not transmit a UWB response message even if a UWB broadcast message including the registered broadcast address is received. In an embodiment, that the external electronic device 220 has registered a broadcast address may mean that the external electronic device 220 has already received a UWB broadcast message including the corresponding broadcast address and has transmitted a UWB response message to the corresponding UWB broadcast message.

Upon receiving the UWB response message from the external electronic device 220, the electronic device 101 may confirm that the transmission of the UWB broadcast message was successful in operation 629, and accordingly, may determine to initiate a UWB ranging operation. The electronic device 101 may transmit a UWB ranging request message to the external electronic device 220 in operation 631 . In one embodiment, the UWB ranging request message may be implemented as a frame specified in the IEEE 802.15.4/4z standard. Upon receiving the UWB ranging request message from the electronic device 101, the external electronic device 220 may transmit a UWB ranging response message, which is a response message to the UWB ranging request message, to the electronic device 101 in operation 633. In one embodiment, the UWB ranging response message may be implemented as a frame specified in the IEEE 802.15.4/4z standard.

Upon receiving the UWB ranging response message from the external electronic device 220, the electronic device 101 may estimate the distance between the electronic device 101 and the external electronic device 220 based on the received UWB ranging response message in operation 635. For example, the electronic device 101 may estimate the distance between the electronic device 101 and the external electronic device 220 based on a time difference of arrival (TDoA) method.

The external electronic device 220 that has transmitted the UWB ranging response message to the electronic device 101 may estimate a distance between the external electronic device 220 and the electronic device 201 in operation 637 . For example, the external electronic device 220 may estimate a distance between the external electronic device 220 and the electronic device 101 based on the TDoA method.

After estimating the distance between the electronic device 101 and the external electronic device 220, the electronic device 101 may check whether the distance between the electronic device 101 and the external electronic device 220 estimated in operation 639 is equal to or less than a threshold distance. When the estimated distance between the electronic device 101 and the external electronic device 220 is less than or equal to the threshold distance, the electronic device 101 may perform a setting operation. In an embodiment, the setting operation may include an operation of providing information notifying a risk of collision between a vehicle and a pedestrian. In an embodiment, when the estimated distance between the electronic device 101 and the external electronic device 220 is less than or equal to a threshold distance, the electronic device 101 may output a message informing of a risk of collision between a vehicle and a pedestrian.

After estimating the distance between the external electronic device 220 and the electronic device 101, the external electronic device 220 may check whether the distance between the external electronic device 220 and the electronic device 101 estimated in operation 641 is equal to or less than a threshold distance. When the estimated distance between the external electronic device 220 and the electronic device 101 is less than or equal to the threshold distance, the external electronic device 220 may perform a setting operation. In an embodiment, the setting operation may include an operation of providing information notifying a risk of collision between a vehicle and a pedestrian. In one embodiment, when the estimated distance between the external electronic device 220 and the electronic device 101 is less than or equal to a threshold distance, the external electronic device 220 may output a message informing of a collision risk between a vehicle and a pedestrian.

In FIG. 6, since it is assumed that the electronic device 101 selects the external electronic device 220 as the target node UWB device to perform the UWB measurement operation, the case in which operations 631 to 641 are performed between the electronic device 101 and the external electronic device 220 is illustrated. However, when the electronic device 101 includes a plurality of target node UWB devices including the external electronic device 220 as target node UWB devices to perform a UWB measurement operation, the electronic device 101 may perform operations similar to or substantially the same as operations 631 to 641 with each of the plurality of target node UWB devices.

9 is a diagram illustrating an example of an operation process between UWB devices according to an antitrust scheme in a wireless communication network according to various embodiments.

Referring to FIG. 9, the electronic device 101 (eg, the electronic device 101 of FIGS. 1, 2, or 3) may transmit (eg, broadcast) UWB broadcast messages 911 and 941 based on a set period (eg, periodically). In FIG. 9 , the electronic device 101 may be a tagged UWB device whose UWB role is a tag in the distance-based service.

The external electronic device 220 (eg, the electronic device 102 of FIG. 1 or the external electronic device 220 of FIG. 2 or 4 ) may receive the UWB broadcast message 911 transmitted by the electronic device 101 . In FIG. 9 , the external electronic device 220 may be a node UWB device whose UWB role is a node in a distance-based service. Upon receiving the UWB broadcast message 911, the external electronic device 220 may check in operation 921 whether information related to the distance-based service included in the user payload field included in the received UWB broadcast message 911 matches information related to the distance-based service provided by the external electronic device 220.

If information (e.g., service code) related to the distance-based service included in the UWB broadcast message 911 does not match information related to the distance-based service provided by the external electronic device 220, the external electronic device 220 may not perform any further operation.

When information related to the distance-based service included in the UWB broadcast message 911 matches information related to the distance-based service provided by the external electronic device 220, in operation 921, it may be determined whether the broadcast address included in the destination address field included in the UWB broadcast message 911 is a broadcast address set in the external electronic device 220. According to an embodiment, when the antitrust method is used, since the node UWB device uses one of the broadcast addresses included in the broadcast address pool, the external electronic device 220 can check whether the broadcast address included in the destination address field included in the UWB broadcast message 911 is the broadcast address set in the external electronic device 220.

If the broadcast address included in the destination address field included in the UWB broadcast message 911 is not the broadcast address set in the external electronic device 220, the external electronic device 220 may not perform any further operation.

When the broadcast address included in the destination address field included in the UWB broadcast message 911 is a broadcast address set in the external electronic device 220, it can be checked whether the broadcast address included in the UWB broadcast message 911 is registered in the external electronic device 220. In an embodiment, that the external electronic device 220 has registered a broadcast address may mean that the external electronic device 220 has already received a UWB broadcast message including the corresponding broadcast address and has transmitted a UWB response message to the corresponding UWB broadcast message.

If the broadcast address included in the UWB broadcast message 911 is registered in the external electronic device 220, the external electronic device 220 may not perform any further operations.

If the broadcast address included in the UWB broadcast message 911 is not registered in the external electronic device 220, the external electronic device 220 may register the broadcast address included in the UWB broadcast message 911 in operation 921. After registering the broadcast address included in the UWB broadcast message 911 , the external electronic device 220 may transmit a UWB response message 931 that is a response message to the UWB broadcast message 911 .

After transmitting the UWB response message 931, the external electronic device 220 may receive the UWB broadcast message 941 transmitted by the electronic device 101 based on a set period. Upon receiving the UWB broadcast message 941, the external electronic device 220 may perform an operation similar to or substantially the same as that performed in operation 921 in operation 951. However, since the external electronic device 220 has already received the UWB broadcast message 911 transmitted by the electronic device 101 and registered its broadcast address in operation 921, it may not perform any further operations (e.g., it may not transmit a UWB response message). Since the external electronic device 220 may not transmit a UWB response message that is a response message to the UWB broadcast message 941 despite successfully receiving the UWB broadcast message 941, it is possible to reduce (e.g., minimize) the probability of a collision occurring in the same unit time interval in the same radio channel, and provide an opportunity for another node UWB device to be discovered by the tagged UWB device (e.g., the electronic device 101).

Referring to FIG. 11, the tracking zone management method reduces (e.g., minimizes) the probability of collision between UWB devices participating in communication on the same radio channel in the UWB multi-object ranging method and enables real-time distance measurement. It may be a method. According to an embodiment, in the tracking zone management method, the tracking zone may be set by a requester UWB device (eg, a tagged UWB device). The requester UWB device may configure tracking zones based on the number of responder UWB devices (eg, node UWB devices) participating in the UWB measurement operation. In one embodiment, the requester UWB device may reset the tracking zones while operating the tracking zones. In an embodiment, tracking zones may be reset based on the number of responder UWB devices participating in a UWB measurement operation and/or the number of responder UWB devices belonging to each tracking zone.

In one embodiment, when a plurality of tracking zones exist, a priority according to a distance-based service may be assigned to each of the plurality of tracking zones. Priorities assigned to a plurality of tracking zones may be different, and accordingly, differential UWB measurement opportunities may be assigned to each tracking zone.

In an embodiment, each of the responder UWB devices participating in the UWB measurement operation may belong to one tracking zone among a plurality of tracking zones, and each responder UWB device may be assigned a UWB measurement opportunity capable of performing a UWB measurement operation only during a UWB measurement period (e.g., a slot) allocated to a tracking zone to which each responder UWB device belongs. Responder UWB devices belonging to one tracking zone may have equal measurement opportunities. According to an embodiment, information related to a tracking zone may be included in a UWB ranging request message. For example, the requestor UWB device may include information related to the tracking zone to which the responder belongs in the UWB ranging request message, and the responder UWB device receiving the UWB ranging request message may check whether information related to the tracking zone included in the UWB ranging request message matches information related to the tracking zone to which the responder UWB device belongs. In an embodiment, the information related to the tracking zone may include an ID of the tracking zone and information (eg, slot number) of a UWB measurement period set in the corresponding tracking zone.

In FIG. 11 , the electronic device 101 (eg, the electronic device 101 of FIGS. 1, 2, or 3) may set tracking zones for a distance-based service. In FIG. 11 , the electronic device 101 may be a tagged UWB device whose UWB role is a tag in a distance-based service.

The external electronic devices 220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-7, and 220-8 (eg, the electronic device 102 of FIG. 1 or the external electronic device 220 of FIG. 2 or 4) may perform a UWB measurement operation with the electronic device 101. In FIG. 11 , each of the external electronic devices 220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-7, and 220-8 may be a node UWB device having a UWB role in a distance-based service.

In FIG. 11 , the electronic device 101 may set a total of four tracking zones (eg, tracking zone #1 1110, tracking zone #2 1120, tracking zone #3 1130, and tracking zone #4 1140). As shown in FIG. 11, slot #1, slot #2, slot #3, and slot #4 are set as UWB measurement intervals for tracking zone #1 (1110), slot #5 and slot #6 are set as UWB measurement intervals for tracking zone #2 (1120), slot #7 is set as UWB measurement interval for tracking zone #3 (1130), and tracking zone #4 (1140) Slot #8 is set as the UWB measurement period for .

In FIG. 11, a case where the measurement ratio for tracking zone #1 1110, tracking zone #2 1120, tracking zone #3 1130, and tracking zone #4 1140 is 50:25:12.5:12.5 is shown. The tracking zone management scheme shown in FIG. 11 may be suitable for a distance-based service in which the risk increases as the distances between the electronic device 101 and the external electronic devices 220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-7, and 220-8 get closer. For example, if the distance-based service is a pedestrian safety service, the electronic device 101 may be a smartphone or/or wearable device owned by the driver, and each external electronic device (220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-8) each is a smartphone owned by pedestrians. And/or wearable devices. In this case, the risk increases as the distances between the electronic device 101 and the external electronic devices 220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-7, and 220-8 get closer. Therefore, when the UWB measurement operation is performed according to the tracking zone management method as described in FIG. 11, the probability of collision occurrence is reduced (eg, minimized). , real-time distance measurement can be made possible.

In an embodiment, the electronic device 101 measures the UWB measurement operation among the external electronic devices 220-1, 220-2, 220-3, 220-4, 2205-, 220-6, 220-7, and 220-8, and then, in the case of the external electronic devices whose positions are moved, the tracking zone to which the corresponding external electronic devices belong may be changed.

12 is a diagram illustrating an example of an operation process between UWB devices according to an indirect UWB ranging scheme in a wireless communication network according to various embodiments.

Referring to FIG. 12 , in the UWB multi-object ranging method, an indirect ranging method may be used to increase (eg, maximize) the number of UWB devices participating in communication per unit time period in the same radio channel.

In the UWB ranging operation, a distance between UWB devices included in a pair may be estimated based on a difference in packet arrival time generated when exchanging a UWB ranging request message (eg, a UWB ranging request packet) and a UWB ranging response message (eg, a UWB ranging response packet). UWB devices included in a pair can directly perform a UWB ranging operation, and a distance between UWB devices can be measured through this UWB ranging operation. If there is a pair of UWB devices directly performing a UWB ranging operation, and there is a UWB device (eg monitoring UWB device) capable of monitoring (eg, overhearing) the UWB ranging request message and the UWB ranging response message exchanged by the pair of UWB devices, the monitoring UWB device is the UWB ranging request message and UWB ranging response exchanged by the UWB devices directly performing the UWB ranging operation. You can overhear the message.

However, the times at which the UWB ranging request message and the UWB ranging response message arrive to UWB devices directly performing the UWB ranging operation and the times at which the UWB ranging request message and the UWB ranging response message arrive at the monitoring UWB device may be different. The difference between the arrival times of the UWB ranging request message and the UWB ranging response message to the UWB devices directly performing the UWB ranging operation and the arrival times of the UWB ranging request message and the UWB ranging response message to the monitoring UWB device may vary depending on the distance between the monitoring UWB device and the UWB devices directly performing the UWB ranging operation.

According to an embodiment, it is possible to determine how close a monitoring UWB device is located to which UWB device among UWB devices directly performing a UWB ranging operation, based on a difference between arrival times of the UWB ranging request message and UWB ranging response message to UWB devices directly performing the UWB ranging operation and arrival times of the UWB ranging request message and UWB ranging response message to the monitoring UWB device.

In the case of the indirect UWB ranging method according to an embodiment, since it is based on a method of monitoring a UWB ranging request message and a UWB ranging response message exchanged according to the direct UWB ranging method, there may be no restriction on the number of UWB devices capable of participating in a UWB measurement operation. The indirect UWB ranging method, which does not limit the number of UWB devices that can participate in the UWB measurement operation, can be operated more efficiently when a distance-based service is required in an environment where a large number of UWB devices are concentrated.

In an embodiment, whether to perform a UWB measurement operation based on a direct UWB ranging method or an indirect UWB ranging method may be determined according to characteristics of a distance-based service. For example, it may be more efficient to use an indirect UWB ranging method rather than a direct UWB ranging method in a distance-based service in which the number of users provided with the distance-based service and/or real-time are more important than accuracy of the distance.

As shown in FIG. 12, a UWB ranging operation may be performed directly between the electronic device 101 (eg, the electronic device 101 of FIGS. 1, 2, or 3) and the external electronic device 220 (eg, the electronic device 102 of FIG. 1 or the external electronic device 220 of FIG. 2 or 4). In FIG. 12 , the electronic device 101 may be a tagged UWB device whose UWB role is a tag in the distance-based service. In FIG. 12 , the external electronic device 220 may be a node UWB device whose UWB role is a node in the distance-based service. The monitoring UWB device 1200 may be a monitoring UWB device capable of receiving a UWB ranging request message and a UWB ranging response message exchanged in a direct UWB ranging operation between the electronic device 101 and the external electronic device 220 .

In FIG. 12 , t2 may represent a system delay time, and t1 may represent a propagation delay time. As shown in FIG. 12 , when the electronic device 101 transmits the UWB ranging request message, the external electronic device 220 may transmit a UWB ranging response message, which is a response message to the UWB ranging request message, after a system delay time t2. The monitoring UWB device 1200 may overhear a UWB ranging request message transmitted from the electronic device 101 to the external electronic device 220, and may overhear a UWB ranging response message transmitted from the external electronic device 220 to the electronic device 101. However, the propagation delay time t1' between the monitoring UWB device 1200 and the electronic device 101 may be longer than the propagation delay time t1 between the electronic device 101 and the external electronic device 220 .
