For example, the electronic device 101 may provide a service together with the external electronic device 102 using wireless communication. For example, the service may include a continuity service. For example, the continuous service may represent a service provided based on two or more electronic devices including the electronic device 101 and the external electronic device 102 sharing context with each other. For example, the continuous service may include the function of displaying or processing content (e.g., web pages and/or electronic documents) displayed or processed within the electronic device 101 within the external electronic device 102. You can. For example, the state of the content displayed or processed within the external electronic device 102 may correspond to the state of the content displayed or processed within the electronic device 101. For example, the continuous service provides a function (e.g., paste) to apply clipboard data acquired using the electronic device 101 to content in the external electronic device 102. It can be included. For example, the continuous service may include a function of controlling the external electronic device 102 using an input means (eg, keyboard and/or mouse) connected to the electronic device 101. However, it is not limited to this.

For example, since the continuous service is provided based on transmitting information, data, and/or content within the electronic device 101, which may be private, to an external electronic device 102, the continuous service For security purposes, the user account used within the electronic device 101 may be provided on the condition that the user account used within the external electronic device 102 corresponds to the user account used within the external electronic device 102. For example, since the continuous service is provided based on transmitting the information, the data, and/or the content, which may be private, to an external electronic device 102, the continuous service is provided using BLE (Bluetooth low BLE communication based on resolving the address of the external electronic device 102 within the electronic device 101 based on the identity resolving key (IRK) of energy (e.g., the IRK of the external electronic device 102) It can be provided through connection. For example, the continuous service is based on interpreting the address of the electronic device 101 within the external electronic device 102 based on the IRK of BLE (e.g., the IRK of the electronic device 101), BLE communication It can be provided through connection.

For example, the IRK of the external electronic device 102 used within the electronic device 101 may be obtained from the server 103. The server 103 may be a server that provides cloud services. For example, the server 103 may be a server that provides a service for managing two or more electronic devices including the electronic device 101 and the external electronic device 102. However, it is not limited to this. For example, the server 103 may send the external electronic device 102 to the connected electronic device 101 based on a user account corresponding to (or the same as) the user account used within the external electronic device 102. A list 150 containing one or more IRKs including the IRK may be provided. For example, the list 150 may be provided through the connection 113 between the electronic device 101 and the server 103. For example, communication techniques for connection 113 can be set in various ways. For example, the connection 113 may be established based on cellular communication, based on wireless local area network (WLAN), or based on BLE communication. However, it is not limited to this.

For example, the IRK of the electronic device 101 used within the external electronic device 102 may be obtained from the server 103. For example, the server 103 includes the IRK of the electronic device 101 to an external electronic device 102 connected based on a user account corresponding to the user account used within the electronic device 101. A list 155 containing one or more IRKs may be provided. For example, list 155 may be the same as list 150 or may be at least partially different from list 150. For example, list 155 may be provided through connection 123. For example, communication techniques for connection 123 can be set in various ways. For example, connection 123 may be established based on cellular communications, established based on WLAN, or established based on BLE communications. However, it is not limited to this.

For example, the IRK of the electronic device 101 and/or the IRK of the external electronic device 102 may be changed. For example, the IRK of the electronic device 101 may be used to initialize the electronic device 101 (e.g., factory reset), reboot the electronic device 101, and/or It may change depending on the turn-off of the power. For example, the IRK of the external electronic device 102 is activated according to initialization of the external electronic device 102, rebooting of the external electronic device 102, and/or turning off the power of the external electronic device 102. , can be changed.

For example, when the list 150 including the IRK of the external electronic device 102 before being changed is received from the server 103 to the electronic device 101 through the connection 113, the electronic device 101 It may be impossible to provide the connection service with the external electronic device 102. For example, when the list 155 including the IRK of the electronic device 101 before being changed is received from the server 103 to the external electronic device 102 through the connection 123, the external electronic device 102 ) may be impossible to provide the connection service together with the electronic device 101.

For example, the state of server 103, the state of connection 113, and the state of connection 123 may change. For example, even if the list 150 includes the IRK of the external electronic device 102 after being changed, the quality of communication from the server 103 is relatively poor or the status (or quality) of the connection 113 is poor. In a relatively poor case, it may be impossible for the electronic device 101 to provide the connection service with the external electronic device 102. For example, even if the list 155 includes the IRK of the electronic device 101 after being changed, the quality of communication from the server 103 is relatively poor or the status (or quality) of the connection 123 is relatively poor. If it is defective, it may be impossible for the external electronic device 102 to provide the connection service together with the electronic device 101.

For example, the electronic device 101 may obtain the IRK of the external electronic device 102 through the connection 112 from the external electronic device 102. For example, connection 112 may be established based on cellular communications, established based on WLAN, or established based on BLE communications. However, it is not limited to this. For example, because the IRK of the external electronic device 102 is obtained via connection 112, the electronic device 101 can determine the quality of communication from the server 103, the status of the connection 113, and the list. Independently of the status of the IRK of the external electronic device 102 within 150, the continuous service may be provided with the external electronic device 102.

For example, the external electronic device 102 may obtain the IRK of the electronic device 101 through the connection 112 from the electronic device 101. For example, because the IRK of the electronic device 101 is obtained via connection 112, the external electronic device 102 can determine the quality of communication from the server 103, the status of the connection 123, and the list. Independently of the status of the IRK of the electronic device 101 within 155, the continuous service may be provided with an external electronic device 102.

The above descriptions and the descriptions below will illustrate that the service is the continuous service, but the operations illustrated below may be applied to other types of services that are distinct from the continuous service.
