Internet of everything (IoE) technology can be an example in which big data processing technology through connection with a cloud server is combined with IoT technology.

In order to implement IoT technology, technology elements such as sensing technology, wired/wireless communication and network infrastructure, service interface technology, and security technology are required, and recently, sensor networks for connection between objects, machine-to-machine communication Various technologies such as (machine to machine: M2M) and machine type communication (MTC) are being studied.

In an IoT environment, an intelligent Internet technology (IT) service that creates new values in human life by collecting and analyzing data generated from connected objects may be provided. IoT technology is a smart home service, smart building service, smart city service, smart car service or connected car service, smart grid service, It can be applied to various services such as health care service, smart home appliance service, or advanced medical service.

Among various services to which IoT technology is applied, in the case of smart home service, various IoT-based services can be provided using various IoT devices.

An electronic device (eg, smart phone) provides location-based services (eg, automation ) service and/or find service). For example, the first external electronic device may include a smart tag (eg, a Samsung Galaxy smart tag), a smart button, and/or a wearable electronic device (eg, a smart watch or ear buds). ) may be included.

In the search service, a target electronic device to be searched for by an electronic device may be a first external electronic device. When the search service is executed, the electronic device may establish a connection (eg, UWB connection) with the first external electronic device based on a short-distance wireless communication method (eg, ultra wide band (UWB) method). The electronic device may obtain a distance and an angle between the electronic device and the first external electronic device through a UWB connection established between the electronic device and the first external electronic device, and may determine the obtained distance and angle between the electronic device and the first external electronic device. Based on this, the location of the first external electronic device may be obtained. The electronic device may display the acquired location of the first external electronic device through a user interface (UI).

When the UWB method is used, the electronic device and the first external electronic device operate as an initiator and a responder, respectively, and through 1:1 communication between the electronic device and the first external electronic device, the electronic device A distance and direction between the and the first external electronic device may be obtained. However, since a UWB antenna generally has a directional radiation pattern, the direction of the electronic device and the direction of the first external electronic device do not match, or an obstacle exists between the electronic device and the first external electronic device, and/or the electronic device. When the distance between the first external electronic device and the first external electronic device is longer than the threshold distance, the electronic device may not be able to receive a UWB signal (eg, a UWB packet) from the first external electronic device. Since the electronic device does not receive a UWB signal from the first external electronic device, stable UWB communication between the electronic device and the first external electronic device may not be guaranteed. For example, when the first external electronic device is attached to a pet such as a dog or cat, the location of the first external electronic device may change very often due to the nature of the pet, which moves a lot. Such very frequent location changes may make it difficult to ensure stable UWB communication between the electronic device and the first external electronic device.

2 is a diagram illustrating an example of a user interface (UI) provided according to a location-based service in a wireless communication network according to various embodiments.

Referring to FIG. 2 , an electronic device (eg, a smart phone) interworks with a first external electronic device and at least one second external electronic device (eg, an IoT device) existing in various spaces within a wireless communication network to determine location based Services (eg, automation services and/or find services) may be provided. For example, the first external electronic device may include a smart tag (eg, a Samsung Galaxy smart tag), a smart button, and/or a wearable electronic device (eg, a smart watch or ear buds). ) may be included.

In the search service, a target electronic device to be searched for by an electronic device may be a first external electronic device. When the search service is executed, the electronic device may establish a connection (eg, UWB connection) with the first external electronic device based on a short-distance wireless communication method (eg, ultra wide band (UWB) method). The electronic device may obtain a distance and an angle between the electronic device and the first external electronic device through a UWB connection established between the electronic device and the first external electronic device, and may determine the obtained distance and angle between the electronic device and the first external electronic device. Based on this, the location of the first external electronic device may be obtained. The electronic device may display the acquired location of the first external electronic device through the UI.

When the UWB scheme is used, the electronic device and the first external electronic device operate as an initiator and a responder, respectively, and through 1:1 communication between the electronic device and the first external electronic device, the electronic device A distance and direction between the and the first external electronic device may be obtained. However, since a UWB antenna generally has a directional radiation pattern, the direction of the electronic device and the direction of the first external electronic device do not match, or an obstacle exists between the electronic device and the first external electronic device, and/or the electronic device. If the distance between the first external electronic device and the first external electronic device is longer than the threshold distance, the electronic device may not be able to receive a UWB signal (eg, a UWB packet) from the first external electronic device. Since the electronic device does not receive a UWB signal from the first external electronic device, stable UWB communication between the electronic device and the first external electronic device may not be guaranteed. For example, when the first external electronic device is attached to a pet such as a dog or cat, the location of the first external electronic device may change very often due to the nature of the pet, which moves a lot. Such very frequent location changes may make it difficult to ensure stable UWB communication between the electronic device and the first external electronic device.

As shown in FIG. 2 , when a search service is executed through an IoT-based application (eg, a Samsung SmartThings application) in an electronic device (210), the electronic device operates on a first external electronic device (eg, a smart tag) may be performed (220). When the electronic device discovers the first external electronic device, the electronic device and the first external electronic device may establish a BLE connection, and information indicating a distance between the electronic device and the first external electronic device through a UI on a BLE finder A message including may be displayed (230). When a UWB connection is established between the electronic device and the first external electronic device, an augmented reality (AR) finder may be executed to perform a scan operation (240). The electronic device may obtain a distance and direction between the electronic device and the first external electronic device through the established UWB connection, and based on the acquired distance and direction between the electronic device and the first external electronic device, control information is provided through a UI on the AR finder. 1 The location of an external electronic device may be displayed (250).

However, since a UWB antenna generally has a directional radiation pattern, the direction of the electronic device and the direction of the first external electronic device do not match, or an obstacle exists between the electronic device and the first external electronic device, and/or the electronic device. If the distance between the first external electronic device and the first external electronic device is longer than the threshold distance, the electronic device may not receive a UWB signal from the first external electronic device (260). In this way, when stable UWB communication between the electronic device and the first external electronic device is not guaranteed, the electronic device cannot acquire the distance and direction between the electronic device and the first external electronic device. If the distance and direction between the electronic device and the first external electronic device are not acquired, the location of the first external electronic device cannot be acquired and the location of the first external electronic device cannot be displayed. Since the location of the first external electronic device is not acquired, the electronic device may perform a search operation for the first external electronic device again (270). For example, when a search operation for the first external electronic device is performed in a state where a BLE connection is not established between the electronic device and the first external electronic device, the electronic device searches for the first external electronic device through the UI, A message (eg, Searching nearby ...) including information indicating that there is may be displayed (270). As another example, when a search operation for the first external electronic device is performed in a state in which a BLE connection is established between the electronic device and the first external electronic device, the electronic device detects the electronic device and the first external electronic device through the UI on the BLE finder. A message including information representing the distance between electronic devices may be displayed (230).

<Equation 1>

11A and 11B are diagrams illustrating another example of a location-based service in a wireless communication network according to various embodiments.

Referring to FIGS. 11A and 11B , the location-based service may be a finding service. The wireless communication network may include the electronic device 101 , a first external electronic device 610 , a second external electronic device 620 , and/or another second external electronic device 1110 . According to an embodiment, the electronic device 101 may be the electronic device 101 of FIG. 1 or 3, the first external electronic device 610 may be the electronic device 102 of FIG. 1, and the second external electronic device 610 may be the electronic device 102 of FIG. The external electronic device 620 and the second external electronic device 1110 cooperate with the electronic device 101 under the control of the electronic device 101 to provide a search service for the first external electronic device 610. can be According to an embodiment, each of the second external electronic device 620 and the other second external electronic device 1110 is an IoT device (eg, a TV, a light, an air conditioner, an oven, or a home appliance such as a speaker) or a user device. (eg, a smart phone or a wearable electronic device). The first external electronic device 610 may provide a search service by interworking with the electronic device 101 . For example, the first external electronic device 610 may be a smart tag (eg, a Samsung Galaxy smart tag), a smart button, or a wearable electronic device (eg, a smart watch or earbuds). According to an embodiment, when a search service is executed through an IoT-based application (eg, Samsung SmartThings application), the electronic device 101 may perform a search operation for the first external electronic device 610 . When the electronic device 101 discovers the first external electronic device 610, it can establish a UWB connection with the first external electronic device 610. In one embodiment, it is assumed that the distance between the electronic device 101 and the first external electronic device 610 may be "a", and the distance a is shorter than a critical distance for establishing a UWB connection. As the UWB connection is established between the electronic device 101 and the first external electronic device 610, an AR finder may be executed to perform a scan operation. The electronic device 101 may acquire the distance and direction between the electronic device 101 and the first external electronic device 610 through the established UWB connection. The electronic device 101 may acquire the location of the first external electronic device 610 based on the obtained distance and direction between the electronic device 101 and the first external electronic device 610, and display the UI on the AR finder. The location of the first external electronic device acquired through this may be displayed (1111).

However, since the UWB antenna has a directional radiation pattern, the direction of the electronic device 101 and the direction of the first external electronic device 610 do not match, or between the electronic device 101 and the first external electronic device 610. When an obstacle exists and/or the distance between the electronic device 101 and the first external electronic device 610 is greater than the critical distance at which a UWB connection can be established, the electronic device 101 may cause the first external electronic device ( 610) may not be able to receive the UWB signal (1113). 11A and 11B, the first external electronic device 610 moves, and accordingly, the distance between the electronic device 101 and the first external electronic device 610 becomes longer than the threshold distance, and thus the electronic device 101 Assume that the UWB signal from the first external electronic device 610 is not received.

When a UWB signal is not received from the first external electronic device 610 for a set time period, the electronic device 101 may select at least one of set helper devices as the second external electronic device 620 . In FIGS. 11A and 11B , it may be assumed that the distance between the electronic device 101 and the first external electronic device 610 is greater than a critical distance that can be measured based on the UWB scheme. Since the distance between the electronic device 101 and the first external electronic device 610 is longer than the critical distance that can be measured based on the UWB method, the electronic device 101 is unable to transmit the UWB from the first external electronic device 610 for a set time. A signal may not be received. In one embodiment, the second external electronic device 620 may be a UWB relay device. The UWB relay device establishes a UWB connection with the first external electronic device 610 according to the request of the electronic device 101 and obtains the location and direction of the first external electronic device 610 through the established UWB connection. It may be an electronic device.

The electronic device 101 may establish a UWB connection with the second external electronic device 620 selected from among set helper devices. In one embodiment, the distance between the electronic device 101 and the second external electronic device 620 may be equal to or shorter than the threshold distance. In one embodiment, the distance between the electronic device 101 and the second external electronic device 620 may be "a". After the electronic device 101 establishes a UWB connection with the second external electronic device 620, the second external electronic device 620 may operate as a UWB relay device for a search service for the first external electronic device 610. It is possible to transmit a first packet requesting that. The first packet may be a packet requesting operation as a UWB relay device for a search service for a target electronic device (eg, the first external electronic device 610). The first packet may be implemented similarly to the first packet described with reference to FIG. 6, and thus a detailed description thereof will be omitted.

Upon receiving the first packet from the electronic device 101, the second external electronic device 620 may establish a UWB connection with the first external electronic device 610 based on the first packet (1115). The distance between the first external electronic device 610 and the second external electronic device 620 is "c", and the distance c between the first external electronic device 610 and the second external electronic device 620 is equal to the threshold distance or or short. After establishing a UWB connection with the first external electronic device 610, the second external electronic device 620 may perform a UWB ranging operation as an initiator based on the first packet. In one embodiment, the second external electronic device 620 is UWB between the second external electronic device 620 and the first external electronic device 610 included in protocol-related information included in the first packet. A UWB ranging operation may be performed as an initiator based on at least one of information related to a ranging protocol to be used for the ranging operation and/or information related to a protocol type supported by the first external electronic device 610 .

As the second external electronic device 620 performs a UWB ranging operation with the first external electronic device 610, the distance and direction between the second external electronic device 620 and the first external electronic device 610 (for example, AoA) can be obtained. After acquiring the distance and direction between the second external electronic device 620 and the first external electronic device 610 , the second external electronic device 620 may transmit a relay packet to the electronic device 101 .

In one embodiment, the third external electronic device 1210 may be the server 108 of FIG. 1 or the third external electronic device 1210 of FIG. 5 . 13A and 13B, a UWB connection may be established between the electronic device 101 and the first external electronic device 610, and the electronic device 101 and the second external electronic device 620 and other second external electronic devices A UWB connection may also be established between each device 1110 .

A BLE GATT connection and a UWB connection are established between the electronic device 101 and the first external electronic device 610, and the electronic device 101 establishes the first external electronic device 610 based on the two-way ranging protocol in operation 1411. ) and UWB communication.

A BLE GATT connection and a UWB connection are established between the second external electronic device 620 and the first external electronic device 610, and the second external electronic device 620 establishes a second external electronic device based on the two-way ranging protocol in operation 1413. 1 UWB communication with the external electronic device 610 may be performed.

In this way, in a state in which a UWB connection is established between the electronic device 101 and the first external electronic device 610 and a UWB connection is established between the second external electronic device 620 and the first external electronic device 610, After establishing a BLE GATT connection with the first external electronic device 610 in operation 1415, the other second external electronic device 1110 may transmit a UWB connection request packet to the first external electronic device 610. In an embodiment, the UWB connection request packet may be a packet requesting a UWB connection based on a two-way ranging protocol.

In one embodiment, it is assumed that the first external electronic device 610 can maintain up to two UWB connections (eg, UWB sessions). Upon receiving a UWB connection request packet requesting a UWB connection based on the two-way ranging protocol from another second external electronic device 1110, in operation 1417, the first external electronic device 610 determines the number of currently established UWB connections. Since the number is two (eg, UWB connection between the electronic device 101 and the first external electronic device 610 and UWB connection between the second external electronic device 620 and the first external electronic device 610), no more It can be seen that it is impossible to establish a UWB connection based on the two-way ranging protocol. Accordingly, the first external electronic device 610 can confirm that the ranging protocol needs to be changed from the two-way ranging protocol to the one-way ranging protocol.

After confirming that the ranging protocol needs to be changed from the two-way ranging protocol to the one-way ranging protocol, the first external electronic device 610 requests the electronic device 101 to change the ranging protocol in operation 1419, which is a 7th packet. packets can be sent. In an embodiment, a packet requesting a ranging protocol change may include information requesting a change of a ranging protocol from a two-way ranging protocol to a one-way ranging protocol. In one embodiment, a packet requesting a ranging protocol change may be transmitted through a BLE GATT connection.

Upon receiving a packet requesting a ranging protocol change from the first external electronic device 610 through the BLE GATT connection, the electronic device 101 converts the ranging protocol of the first external electronic device 610 to a two-way ranging protocol. It can be confirmed that it needs to be changed to a one-way ranging protocol. After confirming that the ranging protocol of the first external electronic device 610 needs to be changed from the two-way ranging protocol to the one-way ranging protocol, the electronic device 101 determines whether to change the ranging protocol in operation 1421. can be performed. In an embodiment, the operation of determining whether to change the ranging protocol may include an operation of displaying a message indicating that the ranging protocol should be changed through a UI. After displaying a message confirming whether or not to change the ranging protocol, the electronic device 101 determines whether information indicating that the ranging protocol will be switched is input or indicating that the ranging protocol will not be switched (eg, will be maintained). You can check if the information is entered.

When information indicating that the ranging protocol will not be switched is input, in operation 1423, the electronic device 101 provides a response to a packet requesting a ranging protocol change from the first external electronic device 610 through the BLE GATT connection. An eighth packet, which is a packet, may be transmitted. A response packet transmitted from the electronic device 101 to the first external electronic device 610 in operation 1423 may include information indicating rejection of the ranging protocol change request.

The first external electronic device 610 receiving the response packet including information indicating rejection of the ranging protocol change request indicates that changing the ranging protocol of the first external electronic device 610 to the one-way protocol is rejected. It can be checked, and in operation 1425, a UWB connection response packet, which is a response packet to the UWB connection request packet, can be transmitted to the other second external electronic device 1110. A UWB connection response packet transmitted from the first external electronic device 610 to the other second external electronic device 1110 may include information indicating that the UWB connection request of the other second external electronic device 1110 is rejected.

In this way, as the information not to switch the ranging protocol is input, the ranging protocol of the first external electronic device 610 does not change from the two-way ranging protocol to the one-way ranging protocol, and thus the electronic device 101 ) and the first external electronic device 610 based on a two-way ranging protocol, and between the second external electronic device 620 and the first external electronic device 610 based on a two-way ranging protocol. is maintained, and the other second external electronic device 1110 cannot establish a UWB connection with the first external electronic device 610 .

In contrast, in operation 1421, when the electronic device 101 displays a message indicating that the ranging protocol needs to be changed through the UI and then inputs information indicating that the ranging protocol will be switched, the electronic device 101 In operation 1427, an eighth packet, which is a response packet to a packet requesting a ranging protocol change, may be transmitted to the first external electronic device 610 through the BLE GATT connection. The response packet transmitted from the electronic device 101 to the first external electronic device 610 in operation 1427 may include information indicating acceptance of the ranging protocol change request.

Upon receiving the response packet including information indicating acceptance of the ranging protocol change request, the first external electronic device 610 indicates that changing the ranging protocol of the first external electronic device 610 to the one-way protocol is accepted. In operation 1429, a ninth packet, which is a packet notifying the ranging protocol change, may be transmitted to the second external electronic device 620. According to an embodiment, a packet notifying a ranging protocol change may include information notifying a changing of a ranging protocol from a two-way ranging protocol to a one-way ranging protocol. In one embodiment, a packet notifying a ranging protocol change may be transmitted through a BLE GATT connection.

After confirming that the changing of the ranging protocol of the first external electronic device 610 to the one-way protocol is accepted, the electronic device 101 notifies the second external electronic device 1110 of the ranging protocol change in operation 1431. A ninth packet may be transmitted. According to an embodiment, a packet notifying a ranging protocol change may include information notifying a changing of a ranging protocol from a two-way ranging protocol to a one-way ranging protocol. In one embodiment, a packet notifying a ranging protocol change may be transmitted through a BLE GATT connection.

In this way, as the ranging protocol is changed, the ranging protocol of the first external electronic device 610 is changed from a two-way ranging protocol to a one-way ranging protocol. Accordingly, in operation 1433, the electronic device 101 and the first A UWB connection based on a two-way ranging protocol between external electronic devices 610 may be converted into a UWB connection based on a one-way ranging protocol. In an embodiment, the UWB connection based on the two-way ranging protocol between the second external electronic device 620 and the first external electronic device 610 is also converted to a UWB connection based on the one-way ranging protocol in operation 1435. can In an embodiment, the second external electronic device 1110 may establish a UWB connection based on the one-way ranging protocol with the first external electronic device 610 in operation 1437 . In an embodiment, the first external electronic device 610 performs UWB connection between the first external electronic device 610 and the electronic device 101 in operation 1439 and the first external electronic device 610 and the second external electronic device ( 620) from a two-way ranging protocol-based UWB connection to a one-way ranging protocol-based UWB connection, and a one-way ranging protocol-based UWB connection with another second external electronic device 1110 can be set.
