Description

Electronic device supporting non-terrestrial network communication and its operating method

[0001] The present disclosure relates to an electronic device supporting non-terrestrial network communication and an operating method thereof.

[0002] Recently, electronic devices supporting non-terrestrial network communications (e.g., satellite communications) are being actively introduced. For example, electronic devices can communicate with satellites operated by existing satellite communication companies by utilizing their frequencies and communication methods. For example, electronic devices can communicate with satellites using cellular frequencies based on the LTE (long-term evolution) standard (or 5G standard). Furthermore, electronic devices can also communicate with satellites based on the 5G NTN (non-terrestrial networks) standard.

[0003] For example, when an electronic device performs communication with a non-terrestrial network based on the LTE standard, some of the frequencies defined in the LTE standard may be allocated to non-terrestrial communication. The electronic device may perform satellite communication using the protocol stack used for terrestrial communication, and an additional protocol stack for non-terrestrial communication may not be required. The electronic device may perform communication without distinguishing between non-terrestrial communication and terrestrial communication. For example, the electronic device may perform a cell scan, camp on a cell that satisfies cell selection criteria, and perform an operation to access the network (e.g., camp on, a random access (RA) procedure, a connection establishment procedure, and / or attach (or registration)). The electronic device may perform an operation to camp on a cell that satisfies cell selection criteria and access the network without distinguishing between non-terrestrial communication and terrestrial communication. Accordingly, electronic devices can be prepared to perform non-terrestrial communications in substantially the same manner as terrestrial communications.

[0004] According to one embodiment, an electronic device may include a memory storing instructions, at least one processor, and an RF circuit. The instructions, when executed by the at least one processor, may cause the electronic device to perform a scan using the RF circuit while the electronic device is not connected to a network. The instructions, when executed by the at least one processor, may cause the electronic device to identify a first cell located around the electronic device based on a result of the scan. The instructions, when executed by the at least one processor, may cause the electronic device to monitor whether a trigger requiring connection to the satellite communication occurs based on a determination that the first cell is associated with the satellite communication. The instructions, when executed by the at least one processor, may cause the electronic device to perform at least one first connection operation for connection to a network based on a determination that the trigger has occurred.

The instructions, when executed by at least one processor of the electronic device, may cause the electronic device to monitor whether a trigger requiring connection to the satellite communication occurs based on a determination that the first cell is associated with the satellite communication. The instructions, when executed by at least one processor of the electronic device, may cause the electronic device to perform at least one first connection operation for connection to a network based on a determination that the trigger has occurred.

The instructions, when executed by the processor, may cause the electronic device to identify a first cell located around the electronic device based on a result of the scan. The instructions, when executed by the processor, may cause the electronic device to perform at least one first connection operation for connection to a network based on the first cell based on the first cell being associated with a terrestrial communication. The instructions, when executed by the processor, may cause the electronic device to postpone performance of at least one first connection operation for connection to a network based on the first cell being associated with satellite communications.

[0008] According to one embodiment, a storage medium storing computer-readable instructions, wherein the instructions, when executed by at least one processor of an electronic device, cause the electronic device to perform a scan while the electronic device is not connected to a network. The instructions, when executed by at least one processor of the electronic device, cause the electronic device to identify a first cell located in the vicinity of the electronic device based on a result of the scan.

[0050] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one 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 module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0051] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0056] FIG. 2A is a block diagram (200) of an electronic device (101) for supporting legacy network communication and 5G network communication according to one embodiment. Referring to FIG. 2A, the electronic device (101) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include at least one processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a portion of the wireless communication module (192). According to another embodiment, the fourth RFIC (228) may be omitted or may be included as a part of the third RFIC (226).

[0057] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. According to one embodiment, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. According to one embodiment, the second cellular network (294) may be a 5G network defined by 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0058] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).

[0059] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.

[0060] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package. According to one embodiment, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2B, the integrated communication processor (260) may support functions for communicating with both the first cellular network (292) and the second cellular network (294).

[0061] As described above, at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260) may be implemented as a single chip or a single package. In this case, the single chip or single package may include a memory (or storage means) that stores instructions that cause the performance of at least some of the operations performed according to one embodiment, and a processing circuit (or, the name thereof is not limited, such as an arithmetic circuit) for executing the instructions.

[0062] The first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first cellular network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).

[0063] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0064] The third RFIC (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).

[0065] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0066] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to an example, at least one antenna module among the first antenna module (242) or the second antenna module (244) can be omitted or combined with another antenna module to process RF signals of a corresponding plurality of bands.

[0067] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0068] According to an exemplary embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.

[0069] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).

[0070] FIG. 3 is a drawing for explaining the connection of an electronic device according to one embodiment.

[0071] According to one embodiment, the electronic device (101) may be located within the coverage area (322) of the satellite (321). Meanwhile, those skilled in the art will understand that the satellite (321) in the present disclosure may be replaced with another type of electronic device that supports non-terrestrial communication. The electronic device (101) may access (323) the satellite (321) within the coverage area (322) of the satellite (321). For example, the electronic device (101) may perform a cell scan within the coverage area (322) of the satellite (321). As a result of performing the cell scan, the electronic device (101) may identify the satellite (321) (or, may be named a cell corresponding to the satellite (321). If the satellite (321) satisfies the cell selection condition, the electronic device (101) may camp on the satellite (321). The electronic device (101) can camp on a satellite (321) and perform at least one operation for establishing a connection (e.g., a radio resource control (RRC) connection) with the satellite (321). The electronic device (101) can perform a connection to a network. Here, the connection to the network can include, for example, performing at least one operation for attaching (or registering) to a core network (e.g., an MME or an AMF) corresponding to the satellite (321) based on the established connection. The network connection can include, for example, a preceding operation for attaching to the core network (e.g., a camping on, an RA procedure, and / or a procedure for establishing a connection). Accordingly, the connection (323) to the satellite (321) can include, for example, camping on, establishing a connection, and / or attaching, without limitation. Additionally, a disconnect may include, but is not limited to, a detach from the network, a disconnect, and / or an RLF declaration.The coverage (322) of satellite communication may be relatively larger (e.g., 50 times larger) than the coverages (302, 312) of ground base stations (301, 311). The coverage (322) based on satellite communication may cover areas not covered by the coverage (302, 312) of ground communication, for example, and thus, a user may perform communication using the electronic device (101) even in areas where ground communication is not supported.

[0072] For example, satellite communications based on satellites (321) may have limited frequency resources and / or support limited services. Satellite communications may provide limited services such as emergency services (e.g., emergency calls) and / or short message services (SMS), while not supporting other general data transmission and reception services (e.g., video streaming, which may be unrestricted). Satellite communications may support limited bandwidth (e.g., 1.4 MHz) compared to terrestrial communications. For example, satellite communications may have relatively low total cell capacity of 2 to 4 Mbps, even when supporting voice calls and / or data services. In contrast, terrestrial communications may support bandwidths of up to 100 MHz, for example, when carrier aggregation (CA) is enabled, and cell capacities may also exceed 1 Gbps.

[0073] Since satellite communication may require higher costs or provide limited services compared to terrestrial communication, it may be desirable for terminals, including electronic devices (101), to utilize terrestrial communication. For example, even after the electronic device (101) connects (323) to a satellite (321), if terrestrial base stations (301, 311) are detected, it may be desirable to connect to the terrestrial base stations (301, 311). For example, if the electronic device (101) is located in a boundary area (324) or moves (331, 332), the electronic device (101) may frequently reconnect by alternating between satellite communication and terrestrial communication. If satellite communication is defined by a different PLMN than terrestrial communication, the electronic device (101) may repeatedly connect to a new cell when the boundary area (324) or movement (331, 332) occurs. If satellite communication and terrestrial communication are defined as the same PLMN, the electronic device (101) may access the satellite (321) in an area where terrestrial communication has a weak electric field, as satellite communication is not distinguished from terrestrial communication. In addition, there is a possibility that terminals accessing satellite communication may repeatedly perform TAU (tracking area update) as the cell location changes in an idle state. In particular, the signaling overhead ratio of satellite communication (e.g., 20%) may be greater than the signaling overhead ratio of terrestrial communication (e.g., 2%), so frequent access to satellite communication may not be desirable. For example, the bandwidth for satellite communication is 1.4 MHz, which may be less than the bandwidth for terrestrial communication, 20 MHz (or more), so the signaling overhead ratio of satellite communication may be greater than that of terrestrial communication.In addition, even though satellite communication only provides limited services, there is a possibility that the electronic device (101) may repeatedly attempt to connect to the satellite (321) and receive a rejection when attempting a service that satellite communication does not support. For example, if only emergency services and SMS are supported by satellite communication, the electronic device (101) may transmit a packet data network (PDN) connection establishment request when it confirms a trigger for data communication, and may receive a rejection from the network in response. Since the electronic device (101) cannot determine the cause of the rejection, it may continuously transmit PDN connection establishment requests, which may waste satellite communication resources. In addition, if there are a large number of terminals in the coverage area (322) of the satellite (321), there is a possibility that terminals exceeding the number of connected UEs that the satellite (321) can manage may request connection. The electronic device (101) according to the embodiment may be configured to perform at least a part of at least one operation for connecting to a network, rather than performing at least a part of at least one operation for connecting to a network immediately when a satellite (321) is scanned, based on confirmation of a specified trigger. Accordingly, a relatively large number of terminals may be prevented from connecting to satellite communication with respect to the satellite (321), and, for example, when a specified condition is satisfied (for example, a service supported by satellite communication may be requested, but is not limited to an example), the electronic device (101) may connect to the satellite (321).

[0074] FIG. 4A is a diagram for explaining a satellite communication system according to one embodiment.

[0075] Referring to FIG. 4A, a satellite communication operator may operate satellites (341, 342, 343). The satellites (341, 342, 343) may be mobile satellites and / or geostationary satellites, and there is no limitation on their types. The satellites (341, 342, 343) may communicate with an electronic device (101) using, for example, a cellular band. The cellular band may be, for example, an operating band supported by existing E-UTRA and / or NR, but there is no limitation. The satellites (341, 342, 343) may communicate with a radio unit (344) operated by the satellite communication operator using a satellite band. The satellite band may be different from the cellular band, but may be set to be the same in some cases. The satellites (341, 342, 343) may be implemented in a regenerative manner, for example. The satellites (341, 342, 343) may include (or be implemented with) a base station (e.g., an eNode B) if, for example, they are implemented in a regenerative manner. The satellites (341, 342, 343) may be implemented in a bent-pipe manner, for example. If the satellites (341, 342, 343) are implemented in a bent-pipe manner, they may convert the frequency band of a signal received from the electronic device (101) to match the reception band of the ground station, amplify the signal, retransmit the signal, and provide it to the radio unit (344) of the ground station. The bent-pipe satellites (341, 342, 343) may perform a role similar to a repeater, and may, for example, perform conversion, amplification, and / or filtering of an analog signal.

[0076] Through the radio unit (344), the packet core (345) of the satellite communication operator can transmit and receive data corresponding to the electronic device (101). Accordingly, the electronic device (101) can transmit and receive data through the public switched telephone network (PSTN) (346) and / or the public Internet (347). Alternatively, the packet core (345) can relay data to the packet core (348) of a mobile network operator (MNO) through an interface (e.g., S8HR 3GPP interface, but is not limited thereto). Accordingly, the electronic device (101) can transmit and receive data with the PSTN (349) and / or the public Internet (350) through the packet core (348) of the mobile network operator. In one example, as in FIG. 4B, satellites (341, 342, 343) may be operated by a mobile network operator. In this case, as in FIG. 4b, the electronic device (101) can transmit and receive data to and from the PSTN (349) and / or the public Internet (350) through the packet core (348) of the mobile network operator, without relaying the packet core (345) by the satellite communication operator.

[0077] FIG. 5A illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0078] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 501. In one example, the electronic device (101) may perform a scan based on stored information (e.g., may be referred to as a stored scan), but there is no limitation on the type of scan. For example, the electronic device (101) may scan for terrestrial communication preferentially over satellite communication, but this is by way of example and there is no limitation on the priority, and priority-based scans will be described later. The electronic device (101) may identify a first cell that satisfies a cell selection condition based on the scan result in operation 503. For example, the electronic device (101) can determine that the cell selection condition is satisfied when Srxlev is greater than 0 and Squal is greater than 0, and the definitions for Srxlev and Squal are in 3GPP (3 rd generation partnership project) TS (technical specification) 36.331 or 38.331 can be followed.

[0079] According to one embodiment, the electronic device (101) may monitor whether a trigger for satellite communication occurs based on the confirmation that the first cell is associated with satellite communication in operation 505. In contrast to performing at least one operation for network access (e.g., camping on, a random access (RA) procedure, establishing an RRC connection, and / or attaching to a network) immediately when a cell satisfying a cell selection condition is confirmed, the electronic device (101) according to one embodiment may monitor whether a trigger for satellite communication occurs without performing at least some of the at least one operation for network access immediately when a cell satisfying the cell selection condition is confirmed. For example, the electronic device (101) may suspend performing at least some of the at least one operation for network access based on a cell corresponding to satellite communication. In one example, the electronic device (101) may suspend camping on the first cell satisfying the cell selection condition and monitor whether a trigger occurs. In this case, for example, if it is confirmed that a trigger has occurred, the electronic device (101) can perform camp on, RA procedure, establish RRC connection, and / or connect to the network. For example, a state in which the electronic device (101) is delaying camp on may be referred to as the electronic device (101) being in a pre-camp on state. In one example, the electronic device (101) can camp on a first cell that satisfies cell selection conditions, delay subsequent operations (e.g., RA procedure, RRC connection establishment, and / or network attachment) and monitor whether a trigger has occurred. In this case, if it is confirmed that a trigger has occurred, the electronic device (101) can perform operations after camp on (e.g., RA procedure, RRC connection establishment, and / or network attachment). Meanwhile, those skilled in the art will understand that there is no limitation on the delayed operations.The electronic device (101) can determine whether the first cell is associated with satellite communication, for example, based on the PLMN and / or frequency (e.g., ARFCN, but not limited thereto) for the first cell. For example, the electronic device (101) can store information about the PLMN associated with satellite communication. For example, the electronic device (101) can store information that can identify whether the first cell is associated with satellite communication (e.g., PLMN corresponding to satellite communication and / or AFRCN corresponding to satellite communication, but not limited thereto) at the time of manufacturing. For example, the electronic device (101) can receive and store information that can identify whether the first cell is associated with satellite communication from a server operated by a satellite communication service provider and / or a communication network operator. The electronic device (101) can determine whether the first cell is associated with satellite communication based on, for example, whether the PLMN and / or frequency identified as a result of the scan are identical to information that can identify whether the first cell is associated with satellite communication stored in advance, but this is an example and there is no limitation on the determination method. For example, the electronic device (101) can receive information that can identify whether the first cell is associated with satellite communication based on information received from a base station (e.g., a satellite) (e.g., a system information block, which can be SIB1, but is not limited thereto). For example, the electronic device (101) can determine whether the corresponding cell is associated with satellite communication based on information received from the base station, but this is an example and there is no limitation on the determination method.

[0080] According to one embodiment, the electronic device (101) may perform at least one operation for connection to a network based on the first cell, based on the determination that a trigger has occurred according to monitoring, in operation 507. As described above, in one example, if the electronic device (101) determines that a trigger has occurred, the electronic device (101) may perform a camp-on, an RA procedure, establish an RRC connection, and / or connect to a network. In one example, the electronic device (101) camps on a first cell that satisfies cell selection conditions, and monitors whether a trigger occurs while postponing subsequent operations (e.g., RA procedure, establishment of RRC connection, and / or attachment to a network), and if it is confirmed that a trigger has occurred, the electronic device (101) can perform subsequent operations (e.g., RA procedure, establishment of RRC connection, and / or attachment to a network), and there is no limitation on the timing of monitoring the trigger as described above.

[0081] For example, the trigger may be a user input for using satellite communication. For example, the trigger may be an event associated with the use of a service (e.g., emergency service, SMS, call, and / or data communication, but not limited thereto). There is no limitation on the type of trigger, which will be described later. Thereafter, the electronic device (101) may perform at least a portion of at least one operation for connecting to a network (e.g., at least one operation for camp-on, RA procedure, at least one operation for establishing an RRC connection, and / or at least one operation for attach). As described above, when a satellite communication is scanned, the electronic device (101) does not perform at least a portion of the at least one operation for connecting to a network immediately, but performs at least a portion of the at least one operation for connecting to a network based on the occurrence of a trigger associated with the use of satellite communication and / or a service supported by satellite communication. As a result, a relatively large number of terminals can be prevented from connecting to satellite communication, and relatively limited satellite communication resources can be saved.

[0082] FIG. 5b illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0083] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 521. For example, the electronic device (101) may perform the scan based on stored information. For example, the electronic device (101) may scan for terrestrial communication with priority over satellite communication, but this is an example and there is no limitation on the priority, and priority-based scans will be described later. The electronic device (101) may identify a first cell that satisfies a cell selection condition based on the scan result in operation 523. The electronic device (101) may identify whether the first cell is associated with satellite communication in operation 525. As described above, the electronic device (101) can determine whether the first cell is associated with satellite communication based on a comparison result between information that can identify whether it is pre-stored satellite communication (e.g., PLMN and / or frequency corresponding to satellite communication) and information confirmed based on a scan result (e.g., scanned PLMN and / or scanned frequency). Alternatively, the electronic device (101) can determine whether the first cell is associated with satellite communication based on information from the first cell (e.g., system information, which may be SIB1 but is not limited thereto). If the first cell is not associated with satellite communication (e.g., if the first cell is associated with terrestrial communication) (Operation 525-No), the electronic device (101) can perform at least a part of at least one operation for accessing a network based on the first cell in operation 531. If the first cell is associated with satellite communication (operation 525 - yes), the electronic device (101) can monitor whether a trigger has occurred in operation 527.If the monitoring result does not result in a trigger occurrence (Operation 527 - No), the electronic device (101) may continuously perform monitoring. If the monitoring result does result in a trigger occurrence (Operation 527 - Yes), the electronic device (101) may perform at least a part of at least one operation for connection to a network based on the first cell in operation 529. As described above, the electronic device (101) may postpone performing at least a part of at least one operation for connection to a network despite the satisfaction of the cell selection condition, and may perform at least a part of at least one operation for connection to a network based on the confirmation of the occurrence of a trigger associated with satellite communication. As described above, in one example, if the electronic device (101) confirms that a trigger has occurred, the electronic device (101) may perform a camp on procedure, an RA procedure, establishment of an RRC connection, and / or attachment to a network. In one example, the electronic device (101) camps on a first cell that satisfies cell selection conditions, and monitors whether a trigger occurs while postponing subsequent operations (e.g., RA procedure, establishment of RRC connection, and / or attachment to a network), and if it is confirmed that a trigger has occurred, the electronic device (101) can perform subsequent operations (e.g., RA procedure, establishment of RRC connection, and / or attachment to a network), and there is no limitation on the timing of monitoring the trigger as described above.

[0084] FIG. 6A illustrates a flowchart for explaining an operation method of an electronic device according to one embodiment. FIG. 6A will be described with reference to FIG. 6B. FIG. 6B is a diagram for explaining scanning of an electronic device according to one embodiment.

[0085] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may, in operation 601, perform a scan associated with terrestrial communication. For example, the electronic device (101) may store information that can identify satellite communication, as described above, thereby enabling the electronic device (101) to distinguish between terrestrial communication and satellite communication. For example, the electronic device (101) may pre-store information (620) associated with a cell, as in FIG. 6B . Although the information (620) is illustrated as including a frequency as information associated with terrestrial communication and / or satellite communication, this is by way of example, and the type of the information (620) is not limited. For example, the electronic device (101) may perform a scan associated with terrestrial communication based on a PLMN and / or a frequency corresponding to terrestrial communication. For example, in the example of FIG. 6B, the electronic device (101) may scan the frequencies f1 and f3 associated with terrestrial communication with priority over the frequency f2 associated with satellite communication. In operation 603, the electronic device (101) may check whether a cell satisfying a cell selection condition is identified as a result of the scan. If a cell satisfying the cell selection condition is identified (operation 603 - Yes), the electronic device (101) may perform at least a part of at least one operation for connection to the network in operation 605. For example, if a cell associated with terrestrial communication is scanned, the electronic device (101) may immediately perform all operations for connection. If a cell satisfying the cell selection condition is not identified (operation 603 - No), the electronic device (101) may perform a scan associated with satellite communication in operation 607. For example, the electronic device (101) may perform a scan associated with terrestrial communication based on a PLMN and / or frequency corresponding to satellite communication.The electronic device (101) can, in operation 609, determine whether a cell satisfying a cell selection condition is identified as a scan result. For example, the cell selection condition may be set differently for satellite communication and terrestrial communication, but there is no limitation. If a cell associated with satellite communication is not identified (operation 609 - No), the electronic device (101) can, in operation 601, perform a scan associated with terrestrial communication, but this is for example only, and the electronic device (101) may be configured to repeatedly perform scans associated with satellite communication. If a cell associated with satellite communication is identified (operation 609 - Yes), the electronic device (101) can, in operation 611, determine whether a trigger occurs. If a trigger does not occur (operation 611 - No), the electronic device (101) can continuously monitor whether a trigger occurs. When a trigger occurs (action 611 - yes), the electronic device (101) may, in operation 613, perform at least a portion of at least one operation for accessing a network based on a cell associated with satellite communication. As described above, the electronic device (101) may be configured to camp on a cell associated with terrestrial communication preferentially over satellite communication, thereby preventing access to satellite communication even when access to terrestrial communication is possible.

[0086] FIG. 6c illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0087] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan associated with satellite communication in operation 641. In operation 643, the electronic device (101) may determine whether a cell satisfying a cell selection condition is identified as a result of the scan. If a cell satisfying the cell selection condition is not identified (operation 643—No), the electronic device (101) may determine whether a cell satisfying the cell selection condition is identified as a result of the scan associated with terrestrial communication in operation 645. If a cell associated with terrestrial communication satisfying the cell selection condition is identified (operation 645—Yes), the electronic device (101) may camp on a cell associated with terrestrial communication in operation 653. When a cell associated with satellite communication satisfying the cell selection condition is identified (operation 643 - Yes), the electronic device (101) can check whether a trigger for satellite communication occurs in operation 649. As described above, the electronic device (101) can monitor whether a trigger occurs after camping on the corresponding cell, or can monitor whether a trigger occurs without camping on the corresponding cell, and there is no limitation on the monitoring time.

[0088] If a trigger does not occur, as described above, the electronic device (101) may postpone performing at least a part of at least one operation for accessing the network. If the trigger does not occur (Operation 649 - No), the electronic device (101) may, in operation 651, perform a scan associated with terrestrial communication and determine whether a cell satisfying a cell selection condition is identified as a result of the scan. If a cell associated with terrestrial communication satisfying the cell selection condition is identified (Operation 651 - Yes), the electronic device (101) may, in operation 647, perform at least a part of at least one operation for accessing the network based on the cell associated with terrestrial communication. If a cell associated with terrestrial communication satisfying the cell selection condition is not identified (Operation 651 - No), the electronic device (101) may determine whether a trigger occurs in operation 649. The electronic device (101) may perform at least a portion of at least one operation for connecting to a cell-based network associated with terrestrial communication, even before the trigger occurs, if terrestrial communication is available. If the trigger occurs (operation 649 - yes), the electronic device (101) may, in operation 653, perform at least a portion of at least one operation for connecting to a cell-based network associated with satellite communication.

[0089] FIG. 7 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0090] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may, in operation 701, while connected to the first cell, determine whether a cell reselection condition of the second cell is satisfied. Based on the determination of the satisfaction of the cell reselection condition, in operation 703, the electronic device (101) may determine whether the second cell is associated with satellite communication. For example, the same PLMN may be assigned to terrestrial communication and satellite communication. If the cell is associated with satellite communication, the electronic device (101) may not perform cell reselection immediately based on the satisfaction of the cell reselection condition, but may postpone cell reselection until a trigger occurs. If the second cell is not associated with satellite communication (Operation 703 - No), the electronic device (101) may perform cell reselection by camping on the second cell associated with terrestrial communication in operation 709. If the second cell is associated with satellite communication (Operation 703 - Yes), the electronic device (101) may postpone cell reselection and monitor whether a trigger occurs in operation 705. If the trigger does not occur (Operation 705 - No), the electronic device (101) may continue monitoring whether a trigger occurs. If a trigger occurs (Operation 705 - Yes), the electronic device (101) may perform cell reselection by camping on the second cell associated with satellite communication in operation 707. Meanwhile, if the occurrence of a trigger is not confirmed, for example, the electronic device (101) may enter a No service state while maintaining cell reselection.Even in this case, the electronic device (101) may be configured to postpone performing at least a part of at least one operation for connection to a network based on the second cell, and then perform at least a part of at least one operation for connection to a network based on the second cell based on the occurrence of the above-described trigger. Alternatively, the electronic device (101) may be configured to perform a rescan based on the release of the connection with the first cell, and there is no limitation thereto. According to the above, the electronic device (101) may postpone cell reselection and then perform cell reselection based on the occurrence of a trigger, rather than immediately reselecting a cell associated with satellite communication when the cell reselection condition is satisfied.

[0091] FIG. 8A illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0092] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the unified communication processor (260)) may, in operation 801, determine that a reporting condition for handover of a second cell is satisfied while connected to a first cell. For example, the electronic device (101) may receive an RRC reconfiguration message including a measurement object (MO) for the second cell from the first cell. The electronic device (101) may perform a measurement for the second cell based on the MO, and determine that the measurement result for the second cell satisfies the reporting condition (e.g., a B1 event, but without limitation). The electronic device (101) may, in operation 803, determine whether the second cell is associated with satellite communication. If the second cell is not associated with satellite communication (action 803 - No), the electronic device (101) may perform a measurement report for the second cell in operation 809. Thereafter, if a handover command to the second cell is received from the network, the electronic device (101) may perform a handover to the second cell. If the second cell is associated with satellite communication (action 803 - Yes), the electronic device (101) may not perform a measurement report in operation 807. The non-performance of the measurement report here may mean, for example, that the electronic device (101) does not perform a measurement report even though a condition of the measurement report is satisfied, and it will be understood by those skilled in the art that this may be implemented as an instruction such as operation 807, or may be implemented as an instruction such as a conditional statement that the measurement report in the case of being associated with satellite communication is not performed.

[0093] FIG. 8b illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0094] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the unified communication processor (260)) may, in operation 821, receive a handover command to a second cell while connected to a first cell. For example, the electronic device (101) may receive an RRC reconfiguration message including a measurement object (MO) for the second cell from the first cell. The electronic device (101) may perform a measurement for the second cell based on the MO, and may confirm that the measurement result for the second cell satisfies a reporting condition (e.g., a B1 event, but without limitation). The electronic device (101) may perform a measurement report for the second cell based on satisfaction of the reporting condition. The electronic device (101) may receive a handover command to a second cell from the network in response to a measurement report. In operation 823, the electronic device (101) may determine whether the second cell is associated with satellite communication. If the second cell is not associated with satellite communication (operation 823 - No), the electronic device (101) may perform at least one operation for handover to the second cell in operation 829. For example, the electronic device (101) may perform an RA procedure, an RRC connection establishment procedure, and / or a TAU procedure to the second cell, but there is no limitation. If the second cell is associated with satellite communication (operation 823 - Yes), the electronic device (101) may not perform at least one operation for handover in operation 827.Non-performance of at least one operation for handover here may mean, for example, that the electronic device (101) does not perform an operation for handover (e.g., an RA procedure) even though it receives a handover command, and it will be understood by those skilled in the art that this may be implemented as an instruction such as operation 827, or that the handover command in the case of satellite communication may be implemented as an instruction such as a conditional statement that is not performed.

[0095] FIG. 9A illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment. The embodiment of FIG. 9A will be described with reference to FIG. 9B. FIG. 9B is a diagram for explaining a screen displayed on an electronic device according to one embodiment.

[0096] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 901. For example, the electronic device (101) may perform the scan based on stored information. For example, the electronic device (101) may scan for terrestrial communication preferentially over satellite communication, but this is an example and there is no limitation on the priority. The electronic device (101) may identify a first cell that satisfies a cell selection condition based on the scan result in operation 903. The electronic device (101) may provide information associated with satellite communication based on the identification that the first cell is associated with satellite communication in operation 905. For example, as in FIG. 9B , the electronic device (101) may display an indicator (922) indicating that satellite communication has been scanned. For example, the electronic device (101) may display an indicator (922) indicating that satellite communication has been scanned before camping on the first cell, or before performing network registration after camping on the first cell, and there is no limitation on the timing of displaying the indicator (922). The indicator (922) indicating that satellite communication has been scanned may be located, for example, in an indication area (920) where mobile network operator identification information (921) and remaining battery power (923) are displayed, but this is an example, and there is no limitation on its shape and / or display location. The electronic device (101) may display a message (930) inquiring about connection to satellite communication. The message (930) may include, but is not limited to, text indicating that satellite communication is available, a button (931) for causing connection, and / or a button (932) for disallowing connection. For example, designating the button (931) may cause the electronic device (101) to connect to satellite communication.The message (930) may be implemented as a portion of the screen or as a pop-up window covering at least a portion of the existing displayed screen, but there are no limitations. The indicator (922) and the message (930) may be displayed simultaneously, or only one of the two may be displayed. For example, the indicator (922) may be displayed only, and then the message (930) may be displayed based on a user's operation.

[0097] According to one embodiment, the electronic device (101) may, in operation 907, determine whether a user input indicating the use of satellite communication is confirmed, as whether a trigger has occurred. If the user input indicating the use of satellite communication is not confirmed (907-No), the electronic device (101) may continue to monitor whether a user input has occurred. If the user input indicating the use of satellite communication is confirmed (907-Yes), the electronic device (101) may, in operation 909, perform at least a portion of at least one operation for registration with a network based on the first cell. For example, the electronic device (101) may perform at least a portion of at least one operation for registration with a network based on the first cell based on the designation of button (931) in FIG. 9B . Accordingly, if the user does not request communication, the electronic device (101) may not connect to satellite communication, and may connect to satellite communication only when the user requests communication.

[0098] FIG. 10 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0099] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may camp on a first cell associated with satellite communication based on a trigger occurrence in operation 1001. The electronic device (101) may perform at least one operation for connection based on the first cell in operation 1003. The electronic device (101) may determine whether a condition for disconnection from the satellite communication is satisfied in operation 1005. If the condition for disconnection is satisfied (1005-Yes), the electronic device (101) may perform at least one operation for disconnection in operation 1007. The electronic device (101) may perform disconnection relatively early, thereby reducing the number of terminals connected to the satellite communication. For example, in the case of emergency service, continuous communication with the emergency center may be required, so paging reception (or paging monitoring) may be used. For example, the electronic device (101) may perform a disconnection by confirming that the emergency service has been completed as a disconnection condition. In some cases, the electronic device (101) may be configured not to perform a disconnection in the case of an emergency service. Alternatively, the electronic device (101) may perform a disconnection by confirming a user's termination command as a disconnection condition. The disconnection may include, but is not limited to, a detach from the core network, a disconnection, and / or an RLF declaration. For example, in the case of an SMS service, the electronic device (101) may maintain a connection state for a certain period of time after transmitting an SMS to receive a reply.The electronic device (101) may perform a disconnection by checking the passage of a certain period of time after transmitting an SMS as a disconnection condition. Alternatively, the electronic device (101) may be configured to maintain a connection state until it leaves the satellite communication coverage area after satellite communication has begun. Alternatively, the electronic device (101) may provide a UI that asks the user whether to maintain the connection to the satellite communication, and may perform a disconnection based on a disconnection command received through the UI.

[0100] FIG. 11A illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment. The embodiment of FIG. 11A will be described with reference to FIGS. 11B and 11C. FIGS. 11B and 11C are diagrams for explaining a screen displayed on an electronic device according to one embodiment.

[0101] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 1101. For example, the electronic device (101) may perform the scan based on stored information. For example, the electronic device (101) may scan for terrestrial communication preferentially over satellite communication, but this is an example and there is no limitation on the priority. The electronic device (101) may identify a first cell associated with satellite communication that satisfies a cell selection condition based on the scan result in operation 1103. The electronic device (101) may identify whether a service use request is confirmed in operation 1105. For example, the electronic device (101) can check whether a service use request is confirmed before camping on the first cell, or before camping on the first cell and registering with the network, and there is no limitation on the time of confirmation. If the service use request is not confirmed (operation 1105 - No), the electronic device (101) can not perform at least a part of at least one operation for registration with a network based on the first cell in operation 1111. For example, as in FIG. 11B, the electronic device (101) can execute a messenger application and display an execution screen (1130) of the messenger application. The execution screen (1130) can include a text display window (1131) and a SIP (soft input panel) (1132). In one example, the electronic device (101) can confirm an input on the text display window (1131) based on the input of one of the keys of the SIP (1132) as a service use request. Alternatively, in another example, the electronic device (101) may identify a call from SIP (1132) as a service use request.Alternatively, in another example, the electronic device (101) may confirm the execution of a messenger application (or another application) as a service use request, and as described above, the service use request may be implemented in various ways and is not limited.

[0102] If the service use request is confirmed (Operation 1105 - Yes), the electronic device (101) can check whether the requested service is a service supported by satellite communication in Operation 1107. If the requested service is not a service supported by satellite communication (Operation 1107 - No), the electronic device (101) can not perform at least a part of at least one operation for registration with a network based on the first cell in Operation 1111. If the requested service is a service supported by satellite communication (Operation 1107 - Yes), the electronic device (101) can perform at least a part of at least one operation for registration with a network based on the first cell in Operation 1109. For example, referring to FIG. 11C, the electronic device (101) can display an execution screen (1150) of a launcher application and confirm the designation of a web browsing application icon (1151) included in the execution screen (1150) as a service use request. The electronic device (101) can determine whether the requested service is supported by satellite communication. Services supported by satellite communication may be stored in the electronic device (101) during production, downloaded from a server, and / or received via a network, for example, and there are no limitations on how they can be obtained. For example, data communication of a web browsing application may not be supported by satellite communication. In this case, the electronic device (101) may not perform at least a portion of at least one operation for registering with a network corresponding to satellite communication, and may display a screen (1160) (or a pop-up window) explaining that the requested service is not available via satellite communication, as shown in FIG. 11C . In one example, the electronic device (101) may display a screen explaining that the requested service is partially limited by satellite communication.

[0103] FIG. 12 is a flowchart illustrating an operation method of a processor and a communication processor according to one embodiment.

[0104] According to one embodiment, the processor (120) may provide satellite-related information to the communication processor (260) (or the first communication processor (212) and / or the second communication processor (214)) at operation 1200. Alternatively, the communication processor (260) may manage the satellite-related information, and there is no limitation on the management entity thereof. In this case, the communication processor (260) may notify the processor (120) of information indicating that a first cell associated with satellite communication satisfying a cell selection condition has been identified. The communication processor (260) may identify a first cell associated with satellite communication satisfying a cell selection condition based on the scan result at operation 1201. The communication processor (260) may, for example, perform a scan based on satellite-related information (e.g., PLMN and / or frequency) provided from the processor (120) to determine that the first cell is associated with satellite communication, but is not limited thereto. For example, the communication processor (260) may also determine that the first cell is associated with satellite communication based on information from the network (e.g., system information) without information from the processor (120). In operation 1203, the communication processor (260) may notify the processor (120) that the first cell associated with satellite communication is scanned. For example, the electronic device (101) may provide the processor (120) with a message including an identifier indicating satellite communication, but there is no limitation on the method of notification. The communication processor (260) may, since it is before the trigger occurs, postpone the performance of at least a part of at least one operation for connecting to a network based on the first cell. The processor (120) can, in operation 1205, confirm that the first cell currently associated with satellite communication is scanned.

[0105] According to one embodiment, the processor (120) may, in operation 1207, determine whether the requested service is a service supported by satellite communication. As described above, the processor (120) may determine whether the service is supported by satellite communication and determine whether the requested service is a service supported by satellite communication. Meanwhile, the communication processor (260) may request the processor (120) to determine whether the requested service is supported by satellite, and the processor (120) may be implemented to determine whether the currently requested service is a satellite-supported service and provide the result to the communication processor (260). There is no limitation on the entity that determines whether the service is supported by satellite communication. If the requested service is not a service supported by satellite communication (1207-No), the processor (120) may determine not to perform at least a part of at least one operation for connecting to a network based on the first cell in operation 1209. In this case, the processor (120) may not transmit a request for network use to the communication processor (260). If the requested service is a service supported by satellite communication (1207 - Yes), the processor (120) may, in operation 1211, determine to perform at least a portion of at least one operation for connection to a network based on the first cell. In operation 1213, the processor (120) may request the communication processor (260) to perform at least a portion of the at least one operation for connection to a network based on the first cell. In operation 1215, the communication processor (260) may perform at least a portion of the at least one operation for connection to a network based on the first cell based on the receipt of the request. Accordingly, the communication processor (260) may connect to the satellite and transmit and receive data based on the requested service.For example, if the requested service is SMS, the communication processor (260) can transmit data for SMS based on the SMS over NAS method. Alternatively, if the requested service is SMS, the communication processor (260) can establish a PDN connection (or, in the case of 5G, a PDU session) of the IMS and transmit it, and there is no limitation on the transmission method. For example, if the requested service is an emergency call and satellite communication supports it, the communication processor (260) can establish a PDN connection of the IMS and transmit it. For example, if the requested service is data communication and satellite communication supports it, the communication processor (260) can establish a PDN connection of the Internet and transmit it.

[0106] FIG. 13 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0107] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 1301. For example, the electronic device (101) may perform the scan based on stored information. For example, the electronic device (101) may scan for terrestrial communication preferentially over satellite communication, but this is an example and there is no limitation on the priority. The electronic device (101) may identify a first cell associated with satellite communication that satisfies a cell selection condition based on the scan result in operation 1303. The electronic device (101) may perform at least a part of at least one operation for connecting to a network based on the first cell based on the service request in operation 1305. As described above, the electronic device (101) can confirm a service request before camping on the first cell, or before camping on the first cell and connecting to the network, and there is no limitation on the timing of the confirmation. The electronic device (101) may attempt to establish a PDN connection for performing a service based on the first cell in operation 1307. For example, the electronic device (101) may attempt to establish a PDN connection of an APN corresponding to the requested service (or application) (or, in the case of 5G, a PDU session of a DNN corresponding to the requested service). The network may reject a service request that is not supported by satellite communication. The electronic device (101) may receive a PDN connection failure message from the network in operation 1309. The electronic device (101) may confirm that the service cannot be performed based on the information in the PDN connection failure message. The electronic device (101) may not attempt to connect if the same service request is confirmed when the satellite is scanned later.

[0108] FIG. 14 illustrates a flowchart for explaining a method of operating an electronic device according to one embodiment.

[0109] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may, in operation 1401, perform a scan on each of a plurality of cells. Each of the plurality of cells may include a cell associated with terrestrial communication and a cell associated with satellite communication. The electronic device (101) may perform the scan based on, for example, stored information, but there is no limitation on the method of scanning. In operation 1403, the electronic device (101) may select one of the plurality of cells, at least one cell associated with terrestrial communication, based on the scan result. For example, both a cell associated with terrestrial communication and a cell associated with satellite communication may be identified as a scan result, in which case the electronic device (101) may preferentially select the cell associated with terrestrial communication. The electronic device (101) may, in operation 1405, camp on a selected cell and perform at least one operation for connecting to a network. As described above, the electronic device (101) may first camp on a cell associated with terrestrial communication, and if camping on a cell associated with terrestrial communication fails, the electronic device (101) may then camp on a cell associated with satellite communication.

[0110] FIG. 15 illustrates a flowchart for explaining an operating method of an electronic device according to one embodiment.

[0111] According to one embodiment, the electronic device (101) (e.g., the processor (120), the first communication processor (212), the second communication processor (214), and / or the integrated communication processor (260)) may perform a scan in operation 1501. The electronic device (101) may identify a first cell associated with satellite communication that satisfies a cell selection condition based on the scan result in operation 1503. The electronic device (101) may perform at least a portion of at least one operation for connection to a network based on the first cell based on detection of a trigger set for message reception in operation 1505. As described above, the time point of confirmation of the trigger set for monitoring may be before camping on the first cell, or before network connection after camping on the first cell, and there is no limitation. For example, the electronic device (101) needs to check whether a message addressed to the electronic device (101) exists, for example, in an SMS. As an example, the electronic device (101) may detect the expiration of a designated timer as a trigger set for monitoring and camp on the first cell. For example, the expiration time of the timer may be preset or adjusted based on user input. For example, the electronic device (101) may provide a user interface (UI) for adjusting the expiration time of the timer. The UI may include, for example, a visual object for adjusting a message reception cycle based on satellite communication, but there is no limitation on how it is implemented. The UI may be supported by a messaging application or an application for controlling satellite communication, and there is no limitation. If the corresponding function is deactivated based on user input, the electronic device (101) may not perform temporary connection and disconnection.The electronic device (101) may receive a message addressed to the electronic device (101) in operation 1507. If a message exists, the electronic device (101) may receive and provide the message. Thereafter, the electronic device (101) may perform at least one operation for disconnection in operation 1509. If a message does not exist, instead of operation 1507, the electronic device (101) may wait for a message and then perform at least one operation for disconnection. For example, after disconnection is completed, the electronic device (101) may start a timer again, thereby periodically performing temporary connection and disconnection operations, thereby receiving a message addressed to the electronic device (101). Meanwhile, those skilled in the art will understand that in addition to timer-based periodic temporary connection and disconnection operations, temporary connection and disconnection operations may also be performed based on events (e.g., execution of a messenger application).

[0112] According to one embodiment, the electronic device (101) may include a memory (130) for storing instructions, at least one processor (120, 212, 214, 260), and an RF circuit (222, 224, 228, 232, 234). The instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to perform a scan using the RF circuit (222, 224, 228, 232, 234) when the electronic device (101) is not connected to a network. The instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to identify a first cell located in the vicinity of the electronic device (101) based on the scan result. The instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to monitor whether a trigger requiring connection to the satellite communication occurs based on the first cell being identified as being associated with the satellite communication. The above instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to perform at least one first connection operation for connection to a network based on the first cell, based on confirmation that the trigger has occurred.

[0113] According to one embodiment, the instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to continue monitoring the trigger while suspending performance of the at least one first connection operation based on a failure to confirm occurrence of the trigger.

[0114] According to one embodiment, the instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to determine, based on information provided from the first cell, whether the first cell is associated with the satellite communication.

[0115] According to one embodiment, the instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to monitor whether a disconnection condition is satisfied after being connected to the first cell. The instructions, when executed by the at least one processor (120, 212, 214, 260), may cause the electronic device (101) to perform at least one disconnection operation for disconnecting from the first cell based on determining that the disconnection condition is satisfied.
