Use may be restricted. For example, in order to provide the VoLTE emergency call method, an electronic device requires an emergency call IMS (internet protocol (IP) multimedia subsystem) profile negotiated with a communication service provider that supports the VoLTE emergency call method. Electronic devices registered with telecommunication carriers that support only the CS emergency call method may be restricted from using the VoLTE emergency call method because an emergency call IMS profile for the VoLTE emergency call method does not exist.

According to one embodiment, the processor may check whether an emergency call profile of LTE communication corresponding to the home network of the electronic device exists based on detection of movement to the service area. According to one embodiment, when the processor determines that there is no emergency call profile for LTE communication corresponding to the home network of the electronic device, the network performs CS (circuit switching) communication based on connection information with the network to which the electronic device is connected. You can check whether it is supported. According to one embodiment, the processor may obtain an emergency call profile of LTE communication corresponding to the network to which the electronic device is connected based on a determination that the network does not support CS communication. According to one embodiment, the processor may provide an emergency call based on LTE communication based on an emergency call profile of LTE communication corresponding to the network.

According to various embodiments referring to FIG. 2 , the electronic device 101 may include a processor 200, a communication circuit 210, and/or a memory 220. According to one embodiment, the processor 200 may be substantially the same as the processor 120 of FIG. 1 or may be included in the processor 120. The communication circuit 210 may be substantially the same as the wireless communication module 192 of FIG. 1 or may be included in the wireless communication module 192.

According to one embodiment, the processor 200 may be operatively, functionally, and/or electrically connected to the communication circuit 210 and/or the memory 220.

According to various embodiments, the processor 200 may check whether the service area (eg, country) in which the electronic device 101 is located changes. According to one embodiment, the processor 200 may obtain a mobile country code (MCC) and/or a mobile network code (MNC) of a network to which the electronic device 101 is connected. According to one embodiment, the processor 200 combines the MCC of the network to which the electronic device 101 is connected with an MCC included in the PLMN list of an equivalent home public land mobile network (EHPLMN) or an MCC of an international mobile subscriber identity (IMSI). You can compare. The processor 200 may compare the MNC of the network to which the electronic device 101 is connected with the MNC included in the PLMN list of the EHPLMN or the MNC of the IMSI. According to one embodiment, the processor 200 determines that the MCC of the network to which the electronic device 101 is connected matches the MCC included in the PLMN list of the EHPLMN or the MCC of the IMSI, and the MCC of the network to which the electronic device 101 is connected matches the MCC of the network to which the electronic device 101 is connected. If matches the MNC included in the PLMN list of the EHPLMN or the MNC of the IMSI, it may be determined that the electronic device 101 is connected to the network of the home PLMN (HPLMN). According to one embodiment, the processor 200 detects that the MCC of the network to which the electronic device 101 is connected does not match the MCC included in the PLMN list of the EHPLMN or the MCC of the IMSI, or the MCC of the network to which the electronic device 101 is connected does not match. If the MNC does not match the MNC included in the PLMN list of the EHPLMN or the MNC of the IMSI, it may be determined that the service area (e.g., country) of the electronic device 101 has changed. As an example, a service area (e.g., country) may include an area in which the same telecommunication operator operates at least one cellular network. For example, changing the service area (e.g., country) may be referred to as roaming.

According to various embodiments, when the processor 200 determines that the service area (e.g., country) of the electronic device 101 has changed, the processor 200 may check the emergency call method of the network to which the electronic device 101 is connected. According to one embodiment, the processor 200 may check whether the network to which the electronic device 101 is connected supports the VoLTE emergency call method from a control message received from the network to which the electronic device 101 is connected. For example, the processor 200 allows the electronic device 101 to connect based on the value of the “ims-EmergencySupport-r9” field of SIB1 (system information block type 1) received from the network to which the electronic device 101 is connected. You can check whether the network supports the VoLTE emergency call method. For example, if the value of the "ims-EmergencySupport-r9" field of SIB1 is set to "true", the processor 200 may determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call method. . For example, if the value of the "ims-EmergencySupport-r9" field of SIB1 is set to "true", the processor 200 may determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call method. . For example, the processor 200 may display the message “EPS network feature” in a message related to connection acceptance (e.g., attach accept) or a message related to TAU (e.g., tracking area update accept) received from a network to which the electronic device 101 is connected. Based on the value of the “EMC BS” field of “support”, it can be confirmed whether the network to which the electronic device 101 is connected supports the VoLTE emergency call method. For example, if the value of the “EMC BS” field is set to “1”, the processor 200 may determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call method. For example, if the value of the “EMC BS” field is set to “0”, the processor 200 may determine that the network to which the electronic device 101 is connected does not support the VoLTE emergency call method. As an example, the VoLTE emergency call method may include a method of supporting emergency calls through a long term evolution (LTE) network.
