Description

Technical Field

[0001] Embodiments of the present disclosure relate to an electronic device for supporting emergency calls and an operating method thereof. Background Art

[0002] With the development of information communication technology and semiconductor technology, electronic devices can provide various functions. For example, the various functions may include at least one of a call function, a message function, a broadcast function, a wireless Internet function, a camera function, an electronic payment function, a user authentication function, or a music reproduction function.

[0003] When a disaster situation such as a natural disaster and / or an emergency situation such as a fire or a car accident occurs, the electronic device may provide an emergency call or situation notification for emergency assistance for the user of the electronic device. Summary of the invention

[0004] The emergency call function may include a CS emergency call type supporting emergency calls based on a Circuit Switching (CS) network and a Voice over LTE (VoLTE) emergency call type supporting emergency calls based on a Long Term Evolution (LTE) network.

[0005] When an electronic device is registered in the home network of a communication operator that only supports the CS emergency call type, the CS emergency call type can be provided in the home network of the communication operator. When the electronic device moves to a service area (e.g., a country) that does not support CS communication (e.g., in the case of roaming), CS communication is not supported in the network (e.g., roaming network) to which the electronic device is connected, thereby limiting the use of the emergency call function. For example, in order to provide the VoLTE emergency call type, the electronic device requires an emergency Internet Protocol (IP) Multimedia Subsystem (IMS) profile negotiated with a communication operator that supports the VoLTE emergency call function. An electronic device registered in a communication operator that only supports the CS emergency call type does not have an emergency call IMS profile for the VoLTE emergency call type, thereby limiting the use of the VoLTE emergency call type.

[0006] Embodiments of the present disclosure provide an apparatus and method for providing an emergency call function (eg, a VoLTE emergency call type) based on LTE communication in a network that does not support CS communication.

[0007] According to various embodiments, an electronic device may include a memory, a communication circuit, and at least one processor operably connected to the memory and the communication circuit. According to an embodiment, the processor may detect movement to a service area supporting emergency calls based on long term evolution (LTE) communication based on information related to the network to which the electronic device is connected. According to an embodiment, the processor may identify whether there is an emergency call profile for LTE communication corresponding to the home network of the electronic device based on the detection of movement to the service area. According to an embodiment, when it is determined that there is no emergency call profile for LTE communication corresponding to the home network of the electronic device, the processor may identify whether the network supports circuit switching (CS) communication based on connection information of the network to which the electronic device is connected. According to an embodiment, the processor may obtain an emergency call profile for LTE communication based on a determination that the network does not support CS communication, the emergency call profile corresponding to the network to which the electronic device is connected. According to an embodiment, the processor may provide an emergency call based on LTE communication based on an emergency call profile for LTE communication corresponding to the network.

[0008] According to various embodiments, a method for operating an electronic device may include: detecting the movement of the electronic device to a service area that supports emergency calls based on long term evolution (LTE) communications based on information related to a network to which the electronic device is connected. According to an embodiment, the electronic device may identify whether there is an emergency call profile for LTE communications corresponding to a home network of the electronic device based on detecting the movement to the service area. According to an embodiment, when it is determined that there is no emergency call profile for LTE communications corresponding to the home network of the electronic device, the electronic device may identify whether the network supports circuit switched (CS) communications based on connection information of the network to which the electronic device is connected. According to an embodiment, the electronic device may acquire an emergency call profile for LTE communications corresponding to the network to which the electronic device is connected based on a determination that the network does not support CS communications. According to an embodiment, the electronic device may provide an emergency call based on LTE communications based on the emergency call profile for LTE communications corresponding to the network.

[0009] According to an embodiment of the present disclosure, when an electronic device moves to (e.g., roams) a service area (e.g., a country) that does not support circuit switching (CS) communication but supports voice over LTE (VoLTE) emergency call type, the electronic device can provide an emergency call function based on the VoLTE emergency call type in a network that does not support CS communication by obtaining an emergency call profile for the VoLTE emergency call type (e.g., an emergency call IMS profile), and the emergency call profile corresponds to the network to which the electronic device is connected.

According to an embodiment, the auxiliary processor 123 (e.g., a neural processing unit) may include a hardware structure dedicated to artificial intelligence model processing. The artificial intelligence model may be generated by machine learning. For example, such learning may be performed by the electronic device 101 where the artificial intelligence is executed or via a separate server (e.g., server 108).

The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., 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 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))).

A signal or power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0035] According to various embodiments, the antenna module 197 may form a millimeter wave antenna module. According to an embodiment, the millimeter wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and a plurality of antennas (e.g., array antennas), wherein the RFIC is disposed on a first surface (e.g., bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a specified high frequency band (e.g., millimeter wave band), and the plurality of antennas are disposed on a second surface (e.g., top surface or side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the specified high frequency band. For example, the plurality of antennas may include a patch array antenna and / or a dipole array antenna.

[0036] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0037] According to an embodiment, a command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 or the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type from the electronic device 101. According to an embodiment, all or some operations to be executed in the electronic device 101 may be executed in one or more of the external electronic device 102, the external electronic device 104, or the server 108.

The one or more external electronic devices receiving the request may execute at least part of the function or service requested, or execute another function or another service related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 may provide the result as at least a partial reply to the request in the case of further processing the result or in the case of not further processing the result. To this end, cloud computing technology, distributed computing technology, mobile edge computing (MEC) technology or client-server computing technology, for example, may be used.

For example, the service area (e.g., country) may include at least one cellular network operated by the same communication operator. For example, the change of the service area (e.g., country) may be referred to as roaming.

[0047] 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 identify the emergency call type of the network to which the electronic device 101 is connected. According to an embodiment, the processor 200 may identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type based on a control message received from the network to which the electronic device 101 is connected. For example, the processor 200 may identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type based on the value of the "ims-EmergencySupport-r9" field of the system information block type 1 (SIB1) received from the network to which the electronic device 101 is connected. For example, when the value of the "ims-EmergencySupport-r9" field of SIB1 is configured as "true", the processor 200 may determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call type. For example, when the value of the "ims-EmergencySupport-r9" field of SIB1 is configured as "false" or "ims-EmergencySupport-r9" is not configured, the processor 200 can determine that the network to which the electronic device 101 is connected does not support the VoLTE emergency call type. For example, the processor 200 can identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type based on the value of the "EMC BS" field of the "EPS Network Feature Support" of the TAU-related message (e.g., Tracking Area Update Accept) or the connection acceptance-related message (e.g., Attach Accept) received from the network to which the electronic device 101 is connected. For example, when the value of the "EMC BS" field is configured as "1", the processor 200 can determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call type. For example, when the value of the "EMC BS" field is configured as "0", the processor 200 can determine that the network to which the electronic device 101 is connected does not support the VoLTE emergency call type. For example, the VoLTE emergency call type may include a type that supports emergency calls over a Long Term Evolution (LTE) network.

[0048] According to various embodiments, when the network to which the electronic device 101 is connected based on a change in the service area supports a VoLTE emergency call type, the processor 200 may identify whether there is an emergency call profile (e.g., an emergency call IMS profile) of the VoLTE emergency type corresponding to the home network (e.g., HPLMN) of the electronic device 101. According to an embodiment, the processor 200 may identify the MCC and MNC of a user identity module (SIM) (not shown) of the electronic device 101. The processor 200 may identify whether there is an emergency call profile corresponding to the MCC and MNC of the SIM of the electronic device 101 from the emergency call profile information related to the VoLTE emergency call type stored in the memory 220. For example, the emergency call profile information related to the VoLTE emergency call type may include a database of emergency call profiles negotiated to support emergency calls over an LTE network.

[0049] According to various embodiments, when there is no VoLTE emergency call type emergency call profile (e.g., emergency call IMS profile) corresponding to the home network of the electronic device 101, the processor 200 may identify whether the network to which the electronic device 101 is connected supports circuit switching (CS) communication. According to an embodiment, when the Evolved Packet System (EPS) connection type (e.g., EPS attachment type) of the electronic device 101 is "EPS attachment", the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication. For example, the EPS connection type may be identified based on the value of a field of an "EPS attachment result" information element (IE) of a connection acceptance-related or TAU acceptance-related message received from the network to which the electronic device 101 is connected. According to an embodiment, when the EPS connection type (e.g., EPS attachment type) of the electronic device 101 is "combined EPS / IMSI attachment" and the additional update type (e.g., additional update type) is "SMS only", the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication. For example, the additional update type may be identified based on a value of a field of an "Additional Update Type" information element (IE) of a connection acceptance-related or TAU acceptance-related message received from a network to which the electronic device 101 is connected. According to an embodiment, when a service area (e.g., a country) in which the electronic device 101 is located is included in a list of server areas that do not support CS communication (e.g., a list of countries), the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication.

[0050] According to an embodiment, when it is determined that the network to which the electronic device 101 is connected supports CS communication, the processor 200 may control the communication circuit 210 to provide a CS emergency call type. For example, the CS emergency call type may include a type that supports emergency calls through a circuit switched (CS) network. For example, a CS network may include a 2G or 3G communication type network.

[0051] According to various embodiments, when it is determined that the network to which the electronic device 101 is connected does not support CS communication, the processor 200 may obtain a VoLTE emergency call type emergency call profile (e.g., an emergency call IMS profile) corresponding to the network to which the electronic device 101 is connected. According to an embodiment, when it is determined that the network to which the electronic device 101 is connected based on a change in the service area supports the VoLTE emergency call type and does not support CS communication, the processor 200 may identify the MCC and MNC of the network to which the electronic device 101 is connected. For example, the MCC and MNC of the network to which the electronic device 101 is connected may be obtained from the "PLMN identity" information element included in the control message of the network to which the electronic device 101 is connected. According to an embodiment, the processor 200 may obtain an emergency call profile corresponding to the MCC and MNC of the network to which the electronic device 101 is connected from the emergency call profile information related to the VoLTE emergency call type stored in the memory 220.

[0052] According to an embodiment, the processor 200 may control the communication circuit 210 to provide a VoLTE emergency call type based on an emergency call profile corresponding to the MCC and MNC of a network to which the electronic device 101 is connected.

[0053] According to an embodiment, when the emergency call profile corresponding to the MCC and MNC of the network to which the electronic device 101 is connected does not exist in the emergency call profile information related to the VoLTE emergency call type stored in the memory 220, the processor 200 may determine that the emergency call function of the electronic device 101 is restricted. For example, when it is determined that the emergency call function of the electronic device 101 is restricted, the processor 200 may output information (or an alarm message) related to the restriction of the emergency call function to the outside. For example, the information related to the restriction of the emergency call function may be output to a display (not shown) of the electronic device 101.

[0054] According to various embodiments, the communication circuit 210 enables the electronic device 101 to communicate with at least one external electronic device (eg, Figure 1 The communication circuit 210 may be configured to transmit signals and / or data to and / or receive signals and / or data from at least one external electronic device (electronic device 102 or 104 or server 108). For example, the communication circuit 210 may include a radio frequency integrated circuit (RFIC) and / or a radio frequency front end (RFFE) for communicating with at least one external electronic device.

[0055] According to various embodiments, the memory 220 may store various data used by at least one element of the electronic device 101 (e.g., the processor 200 and / or the communication circuit 210). According to an embodiment, the data may include emergency call profile information related to the VoLTE emergency call type (e.g., an emergency call profile database). According to an embodiment, the memory 220 may store various instructions (or programs 340) that can be executed by the processor 200.

[0056] Figure 3 300 is a block diagram illustrating a process for providing emergency call functionality according to various embodiments. For example, Figure 3 The program 340 may include a program stored in Figure 1 The program 140 in the memory 130 or stored in Figure 2 The program in the memory 220.

[0057] According to an embodiment, the program 340 may include an operating system (OS) 342 to control one or more resources of the electronic device 101, middleware 344, or an application 346 executable in the OS 342. The OS 342 may include, for example, an Android TM 、iOS TM , Windows TM , Symbian TM 、TizenT M or Bada TM For example, at least a portion of program 340 may be preloaded on electronic device 101 during manufacturing, or may be downloaded from or updated by an external electronic device (eg, electronic device 102 or 104 or server 108) during user use.

[0058] The OS 342 may control the management (e.g., allocation or deallocation) of one or more system resources (e.g., processes, memory, or power) of the electronic device 101. The OS 342 may additionally or alternatively include one or more drivers to drive other hardware devices of the electronic device 101.

[0059] According to an embodiment, the operating system 342 may include a radio interface layer (RIL) 330, which is used to identify whether the network to which the electronic device 101 is connected supports CS communication by receiving CS communication transmitted from the modem, or to control the emergency call type to be used in the electronic device 101 (e.g., a VoLTE emergency call type or a CS emergency call type).

[0060] The middleware 344 may provide various functions to the application 346 so that the application 346 can use functions or information provided from one or more resources of the electronic device 101. The middleware 344 may include, for example, an application manager 301, a window manager 303, a multimedia manager 305, a resource manager 307, a power manager 309, a database manager 311, a package manager 313, a connection manager 315, a notification manager 317, a location manager 319, a graphic manager 321, a security manager 323, a telephony manager 325, or a voice recognition manager 327.

[0061] The application manager 301 may, for example, manage the life cycle of the application 346. The window manager 303 may, for example, manage one or more graphical user interface (GUI) resources used on the screen. The multimedia manager 305 may, for example, identify one or more formats to be used for playing a media file, and may encode or decode a corresponding media file in the media file using a codec suitable for a corresponding format selected from the one or more formats. The resource manager 307 may, for example, manage the source code of the application 346 or the memory space of the memory 130. For example, the power manager 309 may manage the capacity, temperature, or power of the battery 189, and determine or provide relevant information to be used for the operation of the electronic device 101 based at least in part on the corresponding information of the capacity, temperature, or power of the battery 189. According to an embodiment, the power manager 309 may communicate with a basic input / output system (BIOS) (not shown) of the electronic device 101.

[0062] The database manager 311 can, for example, generate, search, or change a database to be used by the application 346. For example, the database manager 311 can search and obtain the emergency call profile of the home network of the electronic device 101 or the network (e.g., a roaming network) to which the electronic device 101 is connected from the emergency call profile information associated with the VoLTE emergency call method. For example, the database manager 311 may include an IMS framework. For example, the emergency call profile of the home network of the electronic device 101 may include an emergency call profile corresponding to the MCC and MNC included in the SIM of the electronic device 101. For example, the emergency call profile of the network to which the electronic device 101 is connected may include an emergency call profile corresponding to the MCC or MNC obtained from a control message (e.g., SIB1) of the network to which the electronic device 101 is connected.

[0063] The package manager 313 may, for example, manage the installation or update of applications distributed in the form of package files. For example, the connection manager 315 may manage a wireless connection or a direct connection between the electronic device 101 and an external electronic device. For example, the notification manager 317 may provide a function of notifying a user of the occurrence of a specified event (e.g., an incoming call, message, or alarm). For example, the location manager 319 may manage location information about the electronic device 101. The graphic manager 321 may, for example, manage one or more graphic effects to be provided to the user or a user interface associated with one or more graphic effects.

[0064] The security manager 323 may, for example, provide system security or user authentication. The phone manager 325 may, for example, manage a voice call function or a video call function provided by the electronic device 101. The voice recognition manager 327 may, for example, send the user's voice data to the server 108, and receive a command corresponding to a function to be executed on the electronic device 101 from the server 108 based at least in part on the voice data or at least in part on text data converted from the voice data.

[0065] According to an embodiment, the middleware 344 may dynamically delete some existing components or add new components. According to an embodiment, at least a portion of the middleware 344 may be included as a part of the OS 342, or may be implemented as another software separate from the OS 342.

[0066] According to an embodiment, the application 346 may include at least one application program associated with a function provided by the electronic device 101. For example, the application 346 may include a call application program associated with an emergency call function.

[0067] According to various embodiments, an electronic device (e.g., Figure 1 or Figure 2 The electronic device 101 may include a memory (eg, Figure 1 Memory 130 or Figure 2 Memory 220), communication circuits (e.g., Figure 1 The wireless communication module 192 or Figure 2 210) and at least one processor operably connected to the memory and the communication circuit (e.g., Figure 1 The processor 120 or Figure 2Processor 200). According to an embodiment, the processor may detect the movement of a service area that supports emergency calls based on long term evolution (LTE) communication based on information related to the network to which the electronic device is connected. According to an embodiment, the processor may identify whether there is an emergency call profile for LTE communication corresponding to the home network of the electronic device based on the detection of movement to the service area. According to an embodiment, when it is determined that there is no emergency call profile for LTE communication corresponding to the home network of the electronic device, the processor may identify whether the network supports circuit switched (CS) communication based on connection information of the network to which the electronic device is connected. According to an embodiment, the processor may acquire an emergency call profile for LTE communication based on a determination that the network does not support CS communication, the emergency call profile corresponding to the network to which the electronic device is connected. According to an embodiment, the processor may provide an emergency call based on LTE communication based on the emergency call profile for LTE communication corresponding to the network.

[0068] According to various embodiments, in a case where the type of connection of the electronic device to the network is an Evolved Packet System (EPS) connection (EPS attach), the at least one processor may determine that the network does not support CS communication.

[0069] According to various embodiments, the connection type of the electronic device to the network may be acquired from an EPS connection result information element (EPS Attach Result IE) of a TAU accept related message or a connection accept related message received from the network connected to the electronic device.

[0070] According to various embodiments, when the connection type of the electronic device to the network is a combined connection (combined EPS / IMSI attach) and the additional update type is "SMS only", the at least one processor may determine that the network does not support CS communications.

[0071] According to various embodiments, the additional update type may be acquired from an additional update type IE of a TAU accept-related message or a connection accept-related message received from a network to which the electronic device is connected.

[0072] According to various embodiments, in a case where a service area of ​​a network of the electronic device is included in the CS communication restricted service area list, at least one processor may determine that the network does not support CS communication.

[0073] According to various embodiments, at least one processor may acquire an emergency call profile for LTE communication corresponding to a Mobile Country Code (MCC) and a Mobile Network Code (MNC) of a network to which the electronic device is connected.

[0074] According to various embodiments, at least one processor may acquire an emergency call profile for LTE communication in an emergency call profile database for LTE communication stored in a memory, which corresponds to a network to which the electronic device is connected.

[0075] According to various embodiments, in the event that there is an emergency call profile for LTE communication corresponding to a home network of the electronic device, at least one processor may provide an emergency call based on LTE communication based on the profile related to the emergency call for LTE communication.

[0076] According to various embodiments, upon determining that the network supports CS communication, at least one processor may provide an emergency call based on the CS communication.

[0077] Figure 4 400 is a flowchart example for providing an emergency call function in an electronic device according to various embodiments. In the following, the corresponding operations in the embodiments may be performed subsequently, but not necessarily subsequently. For example, the order of the corresponding operations may be changed, and two or more operations may be performed in parallel. For example, Figure 4 The electronic device can be Figure 1 or Figure 2 An electronic device 101.

[0078] According to reference Figure 4 In various embodiments, an electronic device (e.g., Figure 1 The processor 120 or Figure 2 The processor 200 of the embodiment may detect, in operation 401, the movement of the electronic device 101 to a service area that supports emergency calls based on LTE communication (e.g., VoLTE emergency call type). According to an embodiment, the processor 200 may identify whether the service area (e.g., country) in which the electronic device 101 is located has changed based on the MCC and / or MNC of the network to which the electronic device 101 is connected. For example, when 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 MNC of the network to which the electronic device 101 is connected matches the MNC included in the PLMN list of the EHPLMN or the MNC of the IMSI, the processor 200 may determine that the electronic device 101 is connected to the network of the home PLMN (HPLMN). That is, the processor 200 may determine that the service area of ​​the electronic device 101 has not changed. For example, when 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 MNC of the network to which the electronic device 101 is connected does not match the MNC included in the PLMN list of the EHPLMN or the MNC of the IMSI, the processor 200 may determine that the service area (e.g., country) of the electronic device 101 has changed. For example, the service area (e.g., country) may include at least one cellular network operated by the same communication operator. For example, the change of the service area (e.g., country) may be referred to as "roaming".

[0079] According to an embodiment, when it is determined that the service area (e.g., country) of the electronic device 101 has changed, the processor 200 may identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type. For example, the processor 200 may identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type based on the value of the "ims-EmergencySupport-r9" field of the system information block type 1 (SIB1) received from the network to which the electronic device 101 is connected. For example, when the value of the "ims-EmergencySupport-r9" field of SIB1 is configured as "true", the processor 200 may determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call type. For example, when the value of the "ims-EmergencySupport-r9" field of SIB1 is configured as "false" or the "ims-EmergencySupport-r9" field is not configured, the processor 200 may determine that the network to which the electronic device 101 is connected does not support the VoLTE emergency call type. For example, SIB1 may be configured as in Table 1 (eg, TS36.331 standard).

[0080]

Table 1

[0081]

[0082]

[0083] For example, the processor 200 may identify whether the network to which the electronic device 101 is connected supports the VoLTE emergency call type based on the value of the "EMC BS" field of the "EPS network feature support" of the TAU-related message (e.g., Tracking Area Update Accept) or the connection acceptance-related message (e.g., Attach Accept) received from the network to which the electronic device 101 is connected. For example, the "EMC BS" of the "EPS network feature support" of the TAU-related message (e.g., Tracking Area Update Accept) or the connection acceptance-related message (e.g., Attach Accept) may be as defined in Table 2 (e.g., TS24.301 standard).

[0084]

Table 2

[0085]

[0086] For example, when the value of the "EMC BS" field is configured as "1", the processor 200 can determine that the network to which the electronic device 101 is connected supports the VoLTE emergency call type. For example, when the value of the "EMC BS" field is configured as "0", the processor 200 can determine that the network to which the electronic device 101 is connected does not support the VoLTE emergency call type.

[0087] According to various embodiments, in operation 403, an electronic device (eg, Figure 2 The processor 120 or the processor 200 of the electronic device 101 may identify whether there is a VoLTE emergency call type emergency call profile corresponding to the home network (e.g., HPLMN) of the electronic device 101. According to an embodiment, when it is determined that the electronic device 101 moves to a service area that supports the VoLTE emergency call type (e.g., operation 401), the processor 200 may identify whether an emergency call profile corresponding to the MCC and MNC of the SIM (not shown) of the electronic device 101 exists in the emergency call profile information related to the VoLTE emergency call type stored in the memory 220. For example, when the emergency call profile corresponding to the MCC and MNC of the SIM of the electronic device 101 exists in the emergency call profile information related to the VoLTE emergency call type stored in the memory 220, the processor 200 may determine that the VoLTE emergency call type emergency call profile corresponding to the home network of the electronic device 101 exists. For example, when the emergency call profile corresponding to the MCC and MNC of the SIM of the electronic device 101 does not exist in the VoLTE emergency call type-related emergency call profile information stored in the memory 220, the processor 200 may determine that the VoLTE emergency call type emergency call profile corresponding to the home network of the electronic device 101 does not exist. For example, the VoLTE emergency call type-related emergency call profile may include a database of emergency call profiles negotiated to support emergency calls through the LTE network. For example, the VoLTE emergency call type emergency call profile may include an emergency call Internet Protocol (IP) Multimedia Subsystem (IMS) profile.

[0088] According to various embodiments, when it is determined that there is no VoLTE emergency call type emergency call profile corresponding to the home network of the electronic device 101 (for example, if "No" in operation 403), the electronic device (for example, the processor 120 or 200) may identify in operation 405 whether the network to which the electronic device is connected supports CS communication. According to an embodiment, when the Evolved Packet System (EPS) connection type (for example, EPS attachment type) of the electronic device 101 is "EPS attachment" (or "ESP only" (for example, "001")), the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication. For example, as shown in Table 3 (for example, TS24.301 standard), the EPS connection type can be identified based on the value of the field of the "EPS Attachment Result" information element (IE) of the TAU acceptance-related or connection acceptance-related message received from the network to which the electronic device 101 is connected.

[0089]

Table 3

[0090]

[0091] According to an embodiment, when the EPS connection type (e.g., EPS attachment type) of the electronic device 101 is "combined EPS / IMSI attachment" (e.g., "010") and the additional update type (e.g., additional update type) is "SMS only" (e.g., "1"), the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication. For example, the additional update type may be identified based on a value of a field of an "additional update type" information element (IE) of a TAU acceptance-related message or a connection acceptance-related message received from the network to which the electronic device 101 is connected, as shown in Table 4 (e.g., TS24.301 standard).

[0092]

Table 4

[0093]

[0094] According to an embodiment, when the service area (e.g., country) where the electronic device 101 is located is included in the list of service areas that do not support CS communication (e.g., list of countries), the processor 200 may determine that the network to which the electronic device 101 is connected does not support CS communication. When the service area (e.g., country) where the electronic device 101 is located is not included in the list of service areas that do not support CS communication (e.g., list of countries), the processor 200 may determine that the network to which the electronic device 101 is connected supports CS communication.

[0095] According to various embodiments, when it is determined that the network to which the electronic device is connected does not support CS communication (e.g., if "No" in operation 405), the electronic device (e.g., processor 120 or 200) may acquire a VoLTE emergency call type emergency call profile corresponding to the network to which the electronic device 101 is connected in operation 407. According to an embodiment, the processor 200 may acquire an emergency call profile corresponding to the MCC and MNC of the network to which the electronic device 101 is connected from the emergency call profile information related to the VoLTE emergency call type stored in the memory 220. For example, the operation of acquiring the emergency call profile may include a series of operations of reading or loading the emergency call profile corresponding to the MCC and MNC of the network to which the electronic device 101 is connected from the emergency call profile information related to the VoLTE emergency call type stored in the memory 220 (e.g., a database). For example, the MCC and MNC of the network to which the electronic device 101 is connected can be acquired from the "PLMN-identity" information element included in the control message (e.g., SIB1) of the network to which the electronic device 101 is connected, as defined in Table 5 (e.g., TS36.331 standard).

[0098]

[0099] According to various embodiments, when it is determined that there is a VoLTE emergency call type emergency call profile corresponding to the home network of the electronic device 101 (for example, if "yes" in operation 403), or when a VoLTE emergency call type emergency call profile corresponding to the network to which the electronic device 101 is connected is obtained (for example, operation 407), the electronic device (for example, processor 120 or 200) may support emergency calls through the VoLTE emergency call type based on the VoLTE emergency call type emergency call profile in operation 409.

[0100] According to various embodiments, when it is determined that the network to which the electronic device is connected supports CS communication (e.g., if "yes" in operation 405), the electronic device (e.g., processor 120 or 200) may support emergency calls through a CS emergency call type in operation 411. For example, the CS emergency call type may include a type that supports emergency calls through a circuit switched (CS) network. For example, a CS network may include a 2G or 3G communication type network.

[0101] According to various embodiments, the electronic device (e.g., processor 120 or 200) may provide an emergency call function (e.g., VoLTE emergency call function) of the electronic device 101 by acquiring a VoLTE emergency call type emergency call profile corresponding to network information (e.g., MCC and MNC) in a network that does not support CS communication.

[0102] According to various embodiments, when the electronic device (e.g., the processor 120 or 200) fails to acquire an emergency call profile of a VoLTE emergency call type corresponding to a network to which the electronic device 101 is connected, the electronic device may limit the emergency call function of the electronic device 101. According to an embodiment, when an emergency call profile corresponding to the MCC and MNC of the network to which the electronic device 101 is connected does not exist in the emergency call profile information related to the VoLTE emergency call type stored in the memory 220, the processor 200 may determine that the emergency call function of the electronic device 101 is limited. When it is determined that the emergency call function of the electronic device 101 is limited, the processor 200 may output information (or an alarm message) related to the limitation of the emergency call function to the outside.

[0103] Figure 5 FIG. 5 is an example flow chart 500 illustrating initiation of an emergency call in an electronic device according to various embodiments. According to an embodiment, Figure 5 At least some of Figure 4Detailed operations of operation 409 are described below. In the following, the corresponding operations in the embodiment may be performed subsequently, but not necessarily subsequently. For example, the order of the corresponding operations may be changed, and two or more operations may be performed in parallel. For example, Figure 5 The electronic device can be Figure 1 or Figure 2 An electronic device 101.

[0104] According to reference Figure 5 In various embodiments, an electronic device (e.g., Figure 1 The processor 120 or Figure 2 The processor 200) may determine in operation 501 whether to perform the initiation of an emergency call. According to an embodiment, when there is an emergency call profile of a VoLTE emergency call type corresponding to the home network of the electronic device 101 (for example, if it is "yes" in operation 403), or when an emergency call profile of a VoLTE emergency call type corresponding to the network to which the electronic device 101 is connected is obtained (for example, operation 407), the processor 200 may determine that the VoLTE emergency call type is supported. When an emergency call initiation event is detected, the processor 200 may determine to perform the initiation of an emergency call based on the VoLTE emergency call type. When no emergency call initiation event is detected, the processor 200 may determine not to perform the initiation of an emergency call. For example, the emergency call initiation event may occur based on at least one of the execution of a function or application related to the initiation of an emergency call, user input related to the initiation of an emergency call, and reception of a signal related to the initiation of an emergency call.

[0105] According to various embodiments, when it is determined not to perform the initiation of the emergency call (eg, if “NO” in operation 501 ), the electronic device (eg, the processor 120 or 200 ) may end the embodiment for initiating the emergency call.

[0106] According to various embodiments, when it is determined to perform initiation of an emergency call (e.g., if "yes" in operation 501), in operation 503, the electronic device (e.g., processor 120 or 200) may register (or connect to) the LTE communication network based on the VoLTE emergency call type emergency call profile. For example, the VoLTE emergency call type emergency call profile may include an emergency call profile corresponding to the home network of the electronic device 101 or an emergency call profile corresponding to the network to which the electronic device 101 is connected. For example, the operation of registering (or connecting to the LTE communication network) in the LTE communication network based on the VoLTE emergency call type emergency call profile may include an emergency type packet data network (PDN) connection process or an IMS registration process for an emergency session.

[0107] According to various embodiments, in operation 505, the electronic device (eg, processor 120 or 200) may perform an emergency call (or perform initiation thereof) through a registered (or connected) LTE communication network based on a VoLTE emergency call type emergency call profile.

[0108] According to various embodiments, when the electronic device (e.g., processor 120 or 200) fails to register in the LTE communication network (or connect to the LTE communication network) based on the VoLTE emergency call type emergency call profile, the emergency call function of the electronic device 101 may be limited. When it is determined that the emergency call function of the electronic device 101 is limited, the processor 200 may output information (or an alarm message) related to the limitation of the emergency call function to the outside. For example, the information related to the limitation of the emergency call function may be output to a display (not shown) of the electronic device 101.

According to an embodiment, the electronic device may provide an emergency call based on LTE communications based on the emergency call profile for LTE communications corresponding to the network.

[0110] According to various embodiments, the method may include determining that the network does not support CS communication in a case where the type of connection of the electronic device to the network is an Evolved Packet System (EPS) connection (EPS Attach).

[0111] According to various embodiments, the connection type of the electronic device to the network may be acquired from an EPS connection result information element (EPS Attach Result IE) of a TAU accept related message or a connection accept related message received from the network connected to the electronic device.

[0112] According to various embodiments, the method may include determining that the network does not support CS communication if the connection type of the electronic device to the network is a combined connection (combined EPS / IMSI attach) and the additional update type is "SMS only".

[0113] According to various embodiments, the additional update type may be acquired from an additional update type IE of a TAU accept-related message or a connection accept-related message received from a network to which the electronic device is connected.

[0114] According to various embodiments, the method may include, in a case where a service area of ​​a network of the electronic device is included in the CS communication restricted service area list, determining that the network does not support CS communication.

[0115] According to various embodiments, acquiring an emergency call profile for LTE communications may include acquiring an emergency call profile for LTE communications that corresponds to a Mobile Country Code (MCC) and a Mobile Network Code (MNC) of a network to which the electronic device is connected.

[0116] According to various embodiments, acquiring the emergency call profile for LTE communication may include acquiring the emergency call profile for LTE communication in an emergency call profile database for LTE communication stored in the electronic device, which corresponds to a network to which the electronic device is connected.

[0117] According to various embodiments, the method may include providing an emergency call based on LTE communication based on a profile related to emergency calls over LTE communication in a case where there is an emergency call profile for LTE communication corresponding to a home network of the electronic device.

[0118] According to various embodiments, the method may include providing the emergency call based on the CS communication if it is determined that the network supports the CS communication.
