[0023] FIG. 1 is a diagram illustrating an example of a communication system according to various embodiments.

[0024] Referring to FIG. 1, FIG. 1 illustrates an electronic device (101), a public land mobile network (PLMN) (102), and a standalone non-public network (SNPN) (103) in a communication system.

[0025] The electronic device (101) is a device used by a user and communicates with a base station of a PLMN (102) via a wireless channel. The link from the base station of the PLMN (102) to the electronic device (101) is referred to as a downlink (DL), and the link from the electronic device (101) to the base station of the PLMN (102) is referred to as an uplink (UL). In addition, although not shown in FIG. 1, the electronic device (101) can communicate with another electronic device (e.g., a wearable device (201) of FIG. 2) via a wireless channel. At this time, the D2D link (device-to-device link) between the electronic device (101) and the other electronic device is referred to as a sidelink, and the sidelink can be used interchangeably with the PC5 interface. In various embodiments, the electronic device (101) can be operated without the intervention of a user. For example, the electronic device (101) may be a device that performs machine type communication (MTC) and may not be carried by a user. In addition, for example, the electronic device (101) may be an NB (narrowband)-IoT (internet of things) device.

[0026] The electronic device (101) may be referred to as a 'terminal', 'user equipment (UE)', 'customer premises equipment (CPE)', 'mobile station', 'subscriber station', 'remote terminal', 'wireless terminal', 'electronic device', or 'user device' or other terms having equivalent technical meanings.

[0027] PLMN (102) refers to a cellular network deployed by a cellular provider in a specific geographical location. For example, an electronic device (101) can connect to a PLMN (102) based on a subscriber identity module (SIM) profile. For example, a state in which the electronic device (101) is connected to a PLMN (102) may be referred to as a PLMN access mode. For example, the electronic device (101) can receive services from network functions in the PLMN access mode. For example, the electronic device (101) can receive voice service through the PLMN (102). In one example, the voice service may correspond to IMS voice (internet protocol multimedia subsystem voice over PS session). For example, the electronic device (101) can receive emergency service through the PLMN (102).

[0028] SNPN (103) refers to a private network configured separately from PLMN (102). For example, a state in which an electronic device (101) is connected to SNPN (103) may be referred to as SNPN access mode. For example, SNPN (103) may not support voice services. In another example, SNPN (103) may support voice services. For example, SNPN (103) may not support emergency services. In another example, SNPN (103) may support emergency services.

[0029] For example, the electronic device (101) may include dual SIMs. The electronic device (101) including dual SIMs may be connected to the PLMN (102) and the SNPN (103) simultaneously. However, the electronic device (101) may include a single SIM. The electronic device (101) including a single SIM may connect to the SNPN (103). If the SNPN (103) does not support voice (or emergency) services, the electronic device (101) may disconnect from the SNPN (103) and connect to the PLMN (102) to receive voice (or emergency) services. However, disconnecting from the SNPN (103) and connecting to the PLMN (102) is time-consuming. Below, an electronic device, a method, and a non-transitory computer-readable storage medium are described that support voice (or emergency) services through linkage with a wearable device (201) while the electronic device (101) is connected to an SNPN (103) that does not support voice (or emergency) services.

[0044] FIG. 3 is a flowchart illustrating an example of the operations of an electronic device for providing a voice service through a wearable device according to various embodiments. The operations of FIG. 3 may be performed by the electronic device (101) of FIGS. 1 and 2 . For example, at least some of the operations may be controlled by the processor (211) of the electronic device (101). In the following description, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed. For example, at least two operations may be performed in parallel.

[0045] Referring to FIG. 3, in operation 301, the electronic device (101) can identify whether the SNPN (103) supports a voice service based on a voice service indicator received from the SNPN (103).

[0046] In one embodiment, the electronic device (101) may receive (or obtain) a voice service indicator from the SNPN (103) during a registration procedure for the SNPN (103). For example, the voice service indicator may indicate whether a voice service is supported by the SNPN (103). In one example, the voice service indicator may indicate whether IMS voice over PS session is supported by the SNPN (103). For example, the electronic device (101) may identify whether the SNPN (103) supports a voice service based on the received voice indicator. In one example, the electronic device (101) may receive (or obtain) the voice service indicator from an access and mobility function (AMF) associated with the SNPN (103). However, this is merely an example, and the present disclosure is not limited thereto.

[0047] In operation 302, the electronic device (101) can perform voice communication with an external electronic device through the SNPN (103). For example, the electronic device (101) can perform voice communication with the external electronic device through the SNPN (103) based on the identification that the SNPN (103) supports a voice service. For example, the electronic device (101) can transmit a call connection request message to request a call connection with the external electronic device through the SNPN (103). The electronic device (101) can receive a call connection response message through the SNPN (103) in response to the call connection request message. By establishing a call connection in response to the call connection response message, the electronic device (101) can perform voice communication with the external electronic device through the SNPN (103). In another example, the electronic device (101) can receive a call connection request message from an external electronic device via the SNPN (103). The electronic device (101) can perform voice communication with the external electronic device via the SNPN (103) by establishing a call connection in response to the call connection request message.

[0048] In operation 303, the electronic device (101) may transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using a public land mobile network (PLMN) (102).

[0049] In one embodiment, the electronic device (101) may identify whether a first condition is met. For example, the electronic device (101) may identify that the first condition is met based on the identification that the SNPN (103) does not support voice services. In another example, the electronic device (101) may identify that the first condition is not met based on the identification that the SNPN (103) supports voice services.

[0050] In one embodiment, the electronic device (101) can identify whether a second condition is met. For example, the electronic device (101) can identify whether the connection between the electronic device (101) and the wearable device (201) is a connection based on a first radio access technology (RAT) (e.g., Bluetooth).

[0051] For example, the wearable device (201) may be connected to the electronic device (101) via a first RAT (e.g., Bluetooth) prior to receiving the message. The wearable device (201) may be configured to deactivate a second RAT (e.g., long term evolution (LTE), new radio (NR)) while connected to the electronic device (101) via the first RAT. In one example, an operation mode of the wearable device (201) that deactivates the second RAT while the electronic device (101) and the wearable device (201) are connected via the first RAT may be referred to as a flight mode. However, this is merely an example, and the present disclosure is not limited thereto. The wearable device (201) may be configured to deactivate the second RAT in the operation mode. For example, in the operating mode, the wearable device (201) may deactivate (or turn off) at least a portion of the communication circuit (223) of the wearable device (201) associated with the second RAT. Since at least a portion of the communication circuit (223) of the wearable device (201) is deactivated in the operating mode, the power consumption of the wearable device (201) may be reduced. However, since the communication of the wearable device (201) through the second RAT is deactivated in the operating mode, the wearable device (201) cannot connect to the network of the PLMN (102) using the second RAT. Therefore, the electronic device (101) may identify whether the connection between the electronic device (101) and the wearable device (201) is a connection based on the first RAT.

[0052] For example, the electronic device (101) may identify that the second condition is met based on the identification that the connection between the electronic device (101) and the wearable device (201) is a connection based on the first RAT. In another example, the electronic device (101) may identify that the second condition is not met based on the identification that the connection between the electronic device (101) and the wearable device (201) is not a connection based on the first RAT.

[0053] In one embodiment, the electronic device (101) can identify whether the third condition is met. For example, the electronic device (101) can identify whether the subscriber identity module (SIM) profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. If the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different, an additional procedure (e.g., operation (601) of FIG. 6) may be required for call forwarding to the wearable device (201). Therefore, the electronic device (101) can identify whether the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same.

[0054] For example, the electronic device (101) may identify that the third condition is met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. In another example, the electronic device (101) may identify that the third condition is not met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different.

[0055] In one embodiment, the electronic device (101) may transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102) upon identification that the first condition, the second condition, and the third condition are met. However, the present disclosure is not limited thereto. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the first condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the second condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the third condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) based on the identification that at least two of the first to third conditions are met. For example, the message may cause the wearable device (201) to activate the second RAT. For example, the message may cause the wearable device (201) to deactivate an operation mode that deactivates the second RAT. For example, the message may cause the wearable device (201) to perform a registration procedure for the PLMN (102) via the second RAT.

[0056] In operation 304, the electronic device (101) may perform voice communication with an external electronic device through a wearable device (201) connected to a network of a PLMN (102). For example, the electronic device (101) may transmit a call connection request message to the network of the PLMN (102) through the wearable device (201) to request a call connection with the external electronic device. The electronic device (101) may receive a call connection response message through the wearable device (201) in response to the call connection request message. The electronic device (101) may perform voice communication with the external electronic device through the wearable device (201) by establishing a call connection in response to the call connection response message. In another example, the electronic device (101) may receive a call connection request message from an external electronic device through the wearable device (201). The electronic device (101) can perform voice communication with an external electronic device through the wearable device (201) by establishing a call connection in response to a call connection request message.

[0057] FIG. 4 is a diagram illustrating an example of providing a voice service through a wearable device according to various embodiments.

[0058] In the example illustrated in FIG. 4, the electronic device (101) includes a single subscriber identity module (SIM). Since the electronic device (101) includes a single SIM, it cannot be simultaneously connected to a public land mobile network (PLMN) (102) and a standalone non-public network (SNPN) (103). In the example illustrated in FIG. 4, the SNPN (103) does not support voice services.

[0059] Referring to FIG. 4, the access mode of the electronic device (101) may be changed from the PLMN access mode to the SNPN access mode. For example, the PLMN access mode may indicate a state in which the electronic device (101) is connected to the PLMN (102). For example, the SNPN access mode may indicate a state in which the electronic device (101) is connected to the SNPN (103). In one example, the electronic device (101) may change the access mode of the electronic device (101) from the PLMN access mode to the SNPN access mode based on a user input. However, this is merely an example, and the present disclosure is not limited thereto. For example, the electronic device (101) may automatically change the access mode of the electronic device (101) from the PLMN access mode to the SNPN access mode by identifying the SNPN (103) based on a list.

[0060] The electronic device (101) can identify whether conditions for transmitting a message to the wearable device (201) to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102) are met. The conditions may include a first condition, a second condition, and a third condition. However, this is merely an example, and the present disclosure is not limited thereto. For example, the conditions may include only some of the first condition, the second condition, and the third condition. For example, the electronic device (101) can identify whether the SNPN (103) supports a voice service based on a voice service indicator received from the SNPN (103) during a registration procedure for the SNPN (103). The electronic device (101) can identify that the first condition is met based on the identification that the SNPN (103) does not support a voice service. For example, the electronic device (101) can identify a radio access technology (RAT) between the electronic device (101) and the wearable device (201). The electronic device (101) can identify that the second condition is met based on the identification that the identified RAT is a first RAT (e.g., Bluetooth). For example, the electronic device (101) can identify whether the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. The electronic device (101) can identify that the third condition is met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same.

[0061] The electronic device (101) may, upon identification that the conditions are met, transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to a network using the PLMN (102). For example, the message may cause the wearable device (201) to activate a second RAT. For example, the message may cause the wearable device (201) to deactivate an operation mode of the wearable device (201) that deactivates the second RAT. For example, the message may cause the wearable device (201) to perform a registration procedure for the PLMN (102) via the second RAT.

[0062] The electronic device (101) can perform voice communication with an external electronic device through a wearable device (201) connected to a network of a PLMN (102). For example, the electronic device (101) can transmit a call connection request message to the network of the PLMN (102) through the wearable device (201) to request a call connection with the external electronic device. The electronic device (101) can receive a call connection response message through the wearable device (201) in response to the call connection request message. By establishing a call connection in response to the call connection response message, the electronic device (101) can perform voice communication with the external electronic device through the wearable device (201). In another example, the electronic device (101) can receive a call connection request message from an external electronic device through the wearable device (201). The electronic device (101) can perform voice communication with an external electronic device through the wearable device (201) by establishing a call connection in response to a call connection request message.

[0063] FIG. 5 is a flowchart illustrating an example of operations of an electronic device for performing emergency communication via a wearable device according to various embodiments. The operations of FIG. 5 may be performed by the electronic device (101) of FIGS. 1 and 2 . For example, at least some of the operations may be controlled by the processor (211) of the electronic device (101). In the following description, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed. For example, at least two operations may be performed in parallel. For example, the operations of the electronic device (101) illustrated in FIG. 5 may be performed subsequent to or in parallel with the operations of FIG. 3 .

[0064] Referring to FIG. 5, in operation 501, the electronic device (101) can identify whether the SNPN (103) supports emergency services based on an emergency service support indicator received from the SNPN (standalone non-public network (103).

[0065] In one embodiment, the electronic device (101) may receive (or acquire) an emergency service support indicator from the SNPN (103) during a registration procedure for the SNPN (103). For example, the emergency service support indicator may indicate whether the SNPN (103) supports emergency calls. For example, the electronic device (101) may identify whether the SNPN (103) supports emergency services based on the received emergency service support indicator.

[0066] In operation 502, the electronic device (101) may perform emergency communication via the SNPN (103). For example, the electronic device (101) may perform emergency communication via the SNPN (103) based on identification that the SNPN (103) supports emergency services. For example, the electronic device (101) may perform emergency communication via the SNPN (103) based on a user input requesting an emergency call.

[0067] In operation 503, the electronic device (101) may transmit a message to the wearable device (201) requesting that the wearable device (201) establish an emergency call. For example, the electronic device (101) may transmit a message to the wearable device (201) requesting that the wearable device (201) establish an emergency call based on an identification that the SNPN (103) does not support emergency services. For example, the message may cause the wearable device (201) to establish an emergency call using a network of a public land mobile network (PLMN) (102).

[0068] In operation 504, the electronic device (101) can perform emergency communication through the wearable device (201). For example, if an emergency call is established by the wearable device (201), the electronic device (101) can perform emergency communication through the wearable device (201).

[0069] FIG. 6 is a flowchart illustrating an example of operations of an electronic device associated with call forwarding according to various embodiments. The operations of FIG. 6 may be performed by the electronic device (101) of FIGS. 1 and 2 . For example, at least some of the operations may be controlled by the processor (211) of the electronic device (101). In the following description, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed. For example, at least two operations may be performed in parallel.

[0070] Referring to FIG. 6, in operation 601, if the subscriber identity module (SIM) profile of the electronic device (101) and the SIM profile of the wearable device (201) are different, the electronic device (101) may transmit the SIM profile of the wearable device (201) to the PLMN (102) for call forwarding.

[0071] In one embodiment, the electronic device (101) may, in PLMN access mode, identify whether the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. For example, if the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different, a call request from the PLMN (102) may not be received by the wearable device (201).

[0072] In one embodiment, the electronic device (101) may transmit the SIM profile of the wearable device (201) to the PLMN (102) for call forwarding based on identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different. For example, by transmitting the SIM profile of the wearable device (201) to the PLMN (102) for call forwarding, a call to the electronic device (101) may be redirected to a call to the wearable device (201).

[0073] In operation 602, the electronic device (101) can identify whether the standalone non-public network (SNPN) (103) supports a voice service based on a voice service indicator received from the SNPN (103).

[0074] In one embodiment, the electronic device (101) may receive (or obtain) a voice service indicator from the SNPN (103) during a registration procedure for the SNPN (103) to change the access mode of the electronic device (101) from the PLMN access mode to the SNPN access mode. For example, the voice service indicator may indicate whether voice service is supported by the SNPN (103). In one example, the voice service indicator may indicate whether IMS voice over PS session is supported by the SNPN (103). However, this is merely an example and the present disclosure is not limited thereto. In one example, the electronic device (101) may receive (or obtain) a voice service indicator from an access and mobility function (AMF) associated with the SNPN (103). However, this is merely an example and the present disclosure is not limited thereto.

[0075] In operation 603, the electronic device (101) may perform deregistration for call forwarding via the SNPN (103). In one embodiment, the electronic device (101) may perform deregistration for call forwarding via the SNPN (103) based on the identification that the SNPN (103) supports voice services. For example, since the electronic device (101) may perform voice communication with an external electronic device via the SNPN (103) without call forwarding, the electronic device (101) may perform deregistration for call forwarding.

[0076] In operation 604, the electronic device (101) can perform voice communication with an external electronic device through the SNPN (103). For example, the electronic device (101) can transmit a call connection request message to request a call connection with the external electronic device through the SNPN (103). The electronic device (101) can receive a call connection response message through the SNPN (103) in response to the call connection request message. By establishing a call connection in response to the call connection response message, the electronic device (101) can perform voice communication with the external electronic device through the SNPN (103). In another example, the electronic device (101) can receive a call connection request message from an external electronic device through the SNPN (103). By establishing a call connection in response to the call connection request message, the electronic device (101) can perform voice communication with the external electronic device through the SNPN (103).

[0077] In operation 605, the electronic device (101) may transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102).

[0078] In one embodiment, the electronic device (101) may identify whether a first condition is met. For example, the electronic device (101) may identify that the first condition is met based on the identification that the SNPN (103) does not support voice services. In another example, the electronic device (101) may identify that the first condition is not met based on the identification that the SNPN (103) supports voice services.

[0079] In one embodiment, the electronic device (101) can identify whether a second condition is met. For example, the electronic device (101) can identify whether the connection between the electronic device (101) and the wearable device (201) is a connection based on a first radio access technology (RAT) (e.g., Bluetooth).

[0080] For example, the wearable device (201) may be connected to the electronic device (101) via a first RAT (e.g., Bluetooth) prior to receiving the message. The wearable device (201) may be configured to deactivate a second RAT (e.g., long term evolution (LTE), new radio (NR)) while connected to the electronic device (101) via the first RAT. In one example, an operation mode of the wearable device (201) that deactivates the second RAT while the electronic device (101) and the wearable device (201) are connected via the first RAT may be referred to as a flight mode. However, this is merely an example, and the present disclosure is not limited thereto. The wearable device (201) may be configured to deactivate the second RAT in the operation mode. For example, in the operating mode, the wearable device (201) may deactivate (or turn off) at least a portion of the communication circuit (223) of the wearable device (201) associated with the second RAT. Since at least a portion of the communication circuit (223) of the wearable device (201) is deactivated in the operating mode, the power consumption of the wearable device (201) may be reduced. However, since the communication of the wearable device (201) through the second RAT is deactivated in the operating mode, the wearable device (201) cannot connect to the network of the PLMN (102) using the second RAT. Therefore, the electronic device (101) may identify whether the connection between the electronic device (101) and the wearable device (201) is a connection based on the first RAT.

[0081] For example, the electronic device (101) may identify that the second condition is met based on the identification that the connection between the electronic device (101) and the wearable device (201) is a connection based on the first RAT. In another example, the electronic device (101) may identify that the second condition is not met based on the identification that the connection between the electronic device (101) and the wearable device (201) is not a connection based on the first RAT.

[0082] In one embodiment, the electronic device (101) can identify whether the third condition is met. For example, the electronic device (101) can identify whether the subscriber identity module (SIM) profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. If the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different, an additional procedure (e.g., operation (601) of FIG. 6) may be required for call forwarding to the wearable device (201). Therefore, the electronic device (101) can identify whether the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same.

[0083] For example, the electronic device (101) may identify that the third condition is met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are the same. In another example, the electronic device (101) may identify that the third condition is not met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different.

[0084] In one embodiment, the electronic device (101) may transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102) upon identification that the first condition, the second condition, and the third condition are met. However, the present disclosure is not limited thereto. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the first condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the second condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the third condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) based on the identification that at least two of the first to third conditions are met. For example, the message may cause the wearable device (201) to activate the second RAT. For example, the message may cause the wearable device (201) to deactivate an operation mode that deactivates the second RAT. For example, the message may cause the wearable device (201) to perform a registration procedure for the PLMN (102) via the second RAT.

[0085] In operation 606, the electronic device (101) may perform voice communication with an external electronic device through a wearable device (201) connected to a network of a PLMN (102). For example, the electronic device (101) may transmit a call connection request message to the network of the PLMN (102) through the wearable device (201) to request a call connection with the external electronic device. The electronic device (101) may receive a call connection response message through the wearable device (201) in response to the call connection request message. The electronic device (101) may perform voice communication with the external electronic device through the wearable device (201) by establishing a call connection in response to the call connection response message. In another example, the electronic device (101) may receive a call connection request message from an external electronic device through the wearable device (201). The electronic device (101) can perform voice communication with an external electronic device through the wearable device (201) by establishing a call connection in response to a call connection request message.

[0086] FIG. 7 is a flowchart illustrating an example of operations of a wearable device for providing voice services to an electronic device according to various embodiments. The operations of FIG. 7 may be performed by the wearable device (201) of FIG. 2 . For example, at least some of the operations of FIG. 7 may be controlled by the processor (221) of the wearable device (201). In the following description, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed. For example, at least two operations may be performed in parallel.

[0087] Referring to FIG. 7, in operation 701, the wearable device (201) may activate an operation mode of the wearable device (201) associated with a second RAT (e.g., long term evolution (LTE), new radio (NR)) while connected to the electronic device (101) via a first RAT (radio access technology) (e.g., Bluetooth).

[0088] In one embodiment, a wearable device (201) may be connected to an electronic device (101) via a first RAT. The wearable device (201) may be configured to deactivate a second RAT while connected to the electronic device (101) via the first RAT. In one example, an operation mode of the wearable device (201) that deactivates the second RAT while the electronic device (101) and the wearable device (201) are connected via the first RAT may be referred to as a flight mode. However, this is merely an example, and the present disclosure is not limited thereto. The wearable device (201) may be configured to deactivate the second RAT in the operation mode. For example, the wearable device (201) may, in the operating mode, deactivate (or turn off) at least a portion of the communication circuit (223) of the wearable device (201) associated with the second RAT. Since at least a portion of the communication circuit (223) of the wearable device (201) is deactivated in the operating mode, the power consumption of the wearable device (201) may be reduced.

[0089] In operation 702, the wearable device (201) may perform a registration procedure for the PLMN (102) based on receiving a message instructing the wearable device (201) to connect to a network using the PLMN (102).

[0090] In one embodiment, the wearable device (201) may receive (or obtain) a message from the electronic device (101) that instructs the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102) using the first RAT. The wearable device (201) may activate a second RAT based on the message. For example, the wearable device (201) may deactivate an operation mode of the wearable device (201) that deactivates the second RAT based on the message. For example, the wearable device (201) may activate (or turn on) at least a portion of the communication circuit (223) of the wearable device (201) associated with the second RAT based on the message. For example, a wearable device (201) can perform a registration procedure for a PLMN (102).

[0091] In operation 703, the wearable device (201) may display a visual object associated with the second RAT through the display (224) based on performing a registration procedure for the PLMN (102).

[0092] FIG. 8 is a diagram illustrating an exemplary screen of a display of a wearable device that provides voice services to an electronic device according to various embodiments.

[0093] Referring to FIG. 8, the wearable device (201) may be configured to deactivate a second radio access technology (RAT) (e.g., long term evolution (LTE), new radio (NR)) while connected to the electronic device (101) via a first RAT (e.g., Bluetooth). For example, an operation mode of the wearable device (201) that deactivates the second RAT while the wearable device (201) and the electronic device (101) are connected via the first RAT may be referred to as a flight mode. However, this is merely an example, and the present disclosure is not limited thereto. For example, the wearable device (201) may not display a visual object associated with the second RAT on the screen of the display (224) based on the deactivation of the second RAT.

[0094] The wearable device (201) may receive (or obtain) a message from the electronic device (101) for instructing the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102). The wearable device (201) may activate a second RAT based on the message. For example, the wearable device (201) may deactivate an operation mode of the wearable device (201) that deactivates the second RAT based on the message. For example, the wearable device (201) may activate (or turn on) at least a part of a communication circuit (223) of the wearable device (201) associated with the second RAT based on the message. The wearable device (201) may perform a registration procedure for the PLMN (102) using the second RAT. The wearable device (201) can display a visual object (821) associated with the second RAT on the screen of the display (224) of the wearable device (201) based on activating the second RAT.

[0095] As described above, when the electronic device (101) is connected to the SNPN (103), the screen of the display (224) of the wearable device (201) can be changed without direct input from the user to the wearable device (201).

[0096] FIG. 9 is a signal flow diagram illustrating exemplary signaling between an electronic device and a wearable device for providing a voice service according to various embodiments. The operations of FIG. 9 may be performed by the electronic device (101) and / or the wearable device (201) of FIG. 2 . In the following description, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed. For example, at least two operations may be performed in parallel.

[0097] Referring to FIG. 9, in operation 901, the electronic device (101) can identify whether a standalone non-public network (SNPN) (103) supports voice service.

[0098] In one embodiment, the electronic device (101) may receive (or obtain) a voice service indicator from the SNPN (103) during a registration procedure for the SNPN (103). In one example, the electronic device (101) may receive (or obtain) the voice service indicator from an access and mobility function (AMF) associated with the SNPN (103). However, this is merely an example and the present disclosure is not limited thereto. However, the present disclosure is not limited thereto. For example, the voice service indicator may indicate whether a voice service is supported by the SNPN (103). In one example, the voice service indicator may indicate whether IMS voice over PS session is supported by the SNPN (103). However, the present disclosure is not limited thereto. For example, the electronic device (101) can identify whether the SNPN (103) supports a voice service based on the received voice indicator. For example, the electronic device (101) can identify that the first condition for transmitting a message is met based on the identification that the SNPN (103) does not support a voice service. In another example, the electronic device (101) can identify that the first condition for transmitting a message is not met based on the identification that the SNPN (103) supports a voice service.

[0099] In one embodiment, the electronic device (101) can identify whether the connection between the electronic device (101) and the wearable device (201) is a connection based on a first radio access technology (RAT) (e.g., Bluetooth). For example, the electronic device (101) can identify that the second condition for transmitting a message is met based on the identification that the connection between the electronic device (101) and the wearable device (201) is a connection based on the first RAT. In another example, the electronic device (101) can identify that the second condition for transmitting a message is not met based on the identification that the connection between the electronic device (101) and the wearable device (201) is not a connection based on the first RAT.

[0100] In one embodiment, the electronic device (101) can identify whether a subscriber identity module (SIM) profile of the electronic device (101) and a SIM profile of the wearable device (201) are identical. For example, the electronic device (101) can identify that the third condition for transmitting a message is met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are identical. In another example, the electronic device (101) can identify that the third condition for transmitting a message is not met based on the identification that the SIM profile of the electronic device (101) and the SIM profile of the wearable device (201) are different.

[0101] In operation 902, the electronic device (101) may transmit a message to instruct the wearable device (201) to connect to a network (e.g., a base station, a core network (CN)) using the PLMN (102).

[0102] In one embodiment, the electronic device (101) may transmit a message to the wearable device (201) to instruct the wearable device (201) to connect to the network using the PLMN (102) upon identification that the first condition, the second condition, and the third condition are met. However, the present disclosure is not limited thereto. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the first condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the second condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) upon identification that the third condition is met. For example, the electronic device (101) may transmit the message to the wearable device (201) based on the identification that at least two of the first to third conditions are met. For example, the message may cause the wearable device (201) to activate the second RAT. For example, the message may cause the wearable device (201) to deactivate an operation mode that deactivates the second RAT. For example, the message may cause the wearable device (201) to perform a registration procedure for the PLMN (102) via the second RAT.

[0103] In operation 903, the electronic device (101) can perform voice communication with an external electronic device by receiving voice data from the wearable device (201).

[0104] Referring to FIG. 9, in operation 901-1, the wearable device (201) may activate an operation mode of the wearable device (201) associated with a second RAT (e.g., LTE, NR) while connected to the electronic device (101) via a first RAT (e.g., Bluetooth).

[0105] In one embodiment, a wearable device (201) may be connected to an electronic device (101) via a first RAT. The wearable device (201) may be configured to deactivate a second RAT while connected to the electronic device (101) via the first RAT. In one example, an operation mode of the wearable device (201) that deactivates the second RAT while the electronic device (101) and the wearable device (201) are connected via the first RAT may be referred to as a flight mode. However, this is merely an example, and the present disclosure is not limited thereto. The wearable device (201) may be configured to deactivate the second RAT in the operation mode. For example, the wearable device (201) may, in the operating mode, deactivate (or turn off) at least a portion of the communication circuit (223) of the wearable device (201) associated with the second RAT. Since at least a portion of the communication circuit (223) of the wearable device (201) is deactivated in the operating mode, the power consumption of the wearable device (201) may be reduced.
