Description

Method for performing communication connections between electronic devices and non-terrestrial network-based electronic devices

[0001] The present disclosure relates to an electronic device and a method of operating the electronic device, and more specifically to a technology for performing a non-terrestrial network-based communication connection of the electronic device and the electronic device.

[0002] A wireless communication device may be required to limit wireless signal exposure that exceeds a wireless signal exposure limit value. The wireless signal exposure limit value may include power limit values ​​set by domestic or international regulatory bodies. Wireless signal exposure may be expressed as a specific absorption rate (SAR), which represents energy absorption by human tissue per unit mass. Wireless signal exposure may be expressed as a power density (PD), which represents energy absorption per unit area. In an electronic device using various wireless communication methods in multiple frequency bands, a total exposure ratio (TER) may be used, which combines the wireless signal exposures of multiple signals corresponding to each wireless communication method. The TER may be expressed in a combined form of the SAR distribution and the PD distribution.

[0003] The information described above may be provided as related art for the purpose of aiding understanding of this document. None of the foregoing is to be claimed as prior art related to this document, nor is it to be used to determine prior art.

[0004] The electronic device may perform a non-terrestrial network communication connection in response to a request for a non-terrestrial network communication connection. For example, the electronic device may perform a non-terrestrial network communication connection after performing terrestrial network communication. In the situation where non-terrestrial network communication is performed, the electronic device may satisfy the radio signal exposure limit value set by the regulatory authority by maintaining the TER below the maximum allowable TER. However, since TER is calculated based on the transmit power used when performing terrestrial network communication and non-terrestrial network communication, when performing a non-terrestrial network communication connection, the electronic device needs to use only the TER calculated during the previous time period (e.g., the sum of the TER based on the transmit power used during the non-terrestrial network communication connection and the TER based on the transmit power used during the terrestrial network communication connection) from the maximum allowable TER. The TER calculated during the non-terrestrial network communication connection may be determined based on the transmit power in the situation where the electronic device performs terrestrial network communication. For example, it may be determined based on the time-averaged value of the transmit power included in the time interval of the time window.

[0005] The user of an electronic device may need to wait for a time window (e.g., 100 seconds) without performing non-terrestrial network communication in order for the electronic device to comply with radio signal exposure (e.g., SAR, PD) limit values. Waiting for a time window (e.g., 100 seconds) may cause inconvenience to the user. Even though the electronic device can perform non-terrestrial network communication connection after the time corresponding to the TER required in response to a non-terrestrial network communication connection request has elapsed, waiting for a time window (e.g., 100 seconds) may cause inconvenience to the user.

[0006] The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this invention belongs from the description below.

[0007] An electronic device according to one embodiment may include at least one communication circuit that performs terrestrial network communication and / or non-terrestrial network communication. The electronic device may include a memory that stores at least one computer program including instructions. The electronic device may include at least one processor. When the instructions are executed individually or collectively by the at least one processor, the electronic device may be configured to scan at least one connectable non-terrestrial network base station in response to the reception of a non-terrestrial network communication connection request. When the instructions are executed individually or collectively by the at least one processor, the electronic device may be configured to check a total exposure ratio (TER) calculated prior to the reception of the non-terrestrial network communication connection request. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may be configured to check the difference value between the maximum allowable TER and the checked TER. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may be configured to perform a non-terrestrial network communication connection with any one of the at least one scanned connectable non-terrestrial network base station if the difference value is greater than or equal to a set value.

[0008] A method of operation of an electronic device according to one embodiment may include an operation of scanning at least one connectable non-terrestrial network base station in response to receiving a request for a non-terrestrial network communication connection. The method of operation of the electronic device may include an operation of checking a total exposure ratio (TER) calculated prior to receiving the request for a non-terrestrial network communication connection. The method of operation of the electronic device may include an operation of checking a difference value between a maximum allowable TER and the checked TER. If the difference value is greater than or equal to a set value, the method of operation of the electronic device may include an operation of performing a non-terrestrial network communication connection with any one of the at least one scanned connectable non-terrestrial network base station.

[0009] According to one embodiment, a computer-readable recording medium may store instructions that cause the electronic device to perform when executed by a processor of the electronic device. The instructions may cause the electronic device to scan at least one connectable non-terrestrial base station in response to the reception of a request for a non-terrestrial network communication connection. The instructions may cause the electronic device to check a total exposure ratio (TER) calculated prior to the reception of the request for a non-terrestrial network communication connection. The instructions may cause the electronic device to check the difference between the maximum allowable TER and the checked TER. The instructions may enable the electronic device to perform a non-terrestrial network communication connection with any one of the scanned at least one connectable non-terrestrial base station if the difference is greater than or equal to a set value.

[0010] An electronic device may be required to comply with a wireless signal exposure limit value in situations where it switches to non-terrestrial network communication while performing terrestrial network communication, or switches to terrestrial network communication while performing non-terrestrial network communication. TER may be measured including wireless signal exposure during the performance of terrestrial network communication and non-terrestrial network communication. In situations where the electronic device switches between terrestrial network communication and non-terrestrial network communication, in order to comply with the wireless signal exposure limit value, the electronic device may switch communication after a time window, which is the time interval for measuring TER, has elapsed. The electronic device of the present disclosure may perform a non-terrestrial network communication connection in response to the difference between the maximum allowable TER and the calculated TER becoming greater than or equal to a set value, even without waiting for a time window. A user of the electronic device may receive a service based on non-terrestrial network communication even before a time window has elapsed if the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value. The electronic device of the present disclosure can prevent inconvenience caused by waiting time in situations where a user requires a non-terrestrial network communication connection.

[0032] An electronic device (e.g., the electronic device (100) of FIG. 1) can transmit and / or receive data through a terrestrial network and / or a non-terrestrial network.

[0033] A ground network may refer to a network capable of providing data communication through a ground wireless communication device (210). For example, the ground wireless communication device (210) may include a base station located on the ground (e.g., fixed on the ground). The ground wireless communication device (210) may support at least one of the various communication methods supported by the electronic device (100).

[0037] The electronic device (100) can perform wireless communication through a non-ground network when communication with the ground network is impossible or not smooth. Alternatively, the electronic device (100) may perform wireless communication through a non-ground network regardless of the communication status with the ground network depending on the case.

[0038] FIG. 3 is a diagram illustrating a communication connection between an electronic device and a communication network according to one embodiment.

[0039] According to one embodiment, the electronic device (100) may be located within the coverage (315) of a ground wireless communication device (210) (hereinafter referred to as ground wireless communication coverage (315)) and / or the coverage (325) of a non-ground wireless communication device (220) (hereinafter referred to as non-ground wireless communication coverage (325). The non-ground wireless communication coverage (325) may be relatively larger than the ground wireless communication coverage (315) (e.g., 50 times larger). For example, the non-ground wireless communication coverage (325) may cover an area that the coverage (315) of the ground wireless communication device (210) does not cover, and accordingly, the electronic device (100) may perform communication even in an area where ground wireless communication is not supported.

[0044] Referring to FIG. 4, the non-terrestrial network system (400) may include a non-terrestrial wireless communication device (220), a radio unit (415), and a packet core (430).

The non-ground network system (400) may be implemented, for example, in a bent-pipe manner. When implemented in a bent-pipe manner, at least one non-ground wireless communication device (220) may include a repeater that converts (e.g., amplifies) and transmits a signal. There are no limitations on the implementation method of the non-ground network system (400) and the role of the non-ground wireless communication device (220).

[0046] The non-terrestrial wireless communication device (220) may include at least one satellite. The non-terrestrial wireless communication device (220) may communicate with, for example, the electronic device (100) using a terrestrial network (e.g., cellular network) band and / or a non-terrestrial network band. The terrestrial network band may be an operating band supported, for example, by LTE (long term evolution) and / or NR (new radio), but is not limited thereto. The non-terrestrial network band may include the n255 and / or n256 bands defined by 3GPP, but is not limited thereto.

[0047] At least one radio unit (415) can receive a signal from a non-terrestrial wireless communication device (220) and transmit it to a packet core (430). The radio unit (415) and the non-terrestrial wireless communication device (220) can communicate, for example, using a non-terrestrial network band. The non-terrestrial network band may be different from the terrestrial network band, but may be set to be the same in some cases.

[0048] At least one packet core (430) can transmit and receive data associated with the electronic device (100) through a radio unit (415).

[0049] FIG. 5 is a drawing for explaining the TER of an electronic device according to one embodiment.

[0050] The electronic device (100) may be required to limit wireless signal exposure that exceeds a wireless signal exposure limit value. The wireless signal exposure limit value may include a power limit value set by domestic or international regulatory bodies. Wireless signal exposure according to one example may be expressed as a specific absorption rate (SAR), which represents energy absorption by human tissue per unit mass. SAR may have units of W / kg (watts per kilogram). SAR may be used to represent wireless signal exposure for transmission frequencies including wireless communication technologies such as 3G (e.g., CDMA), 4G, or IEEE 802.11ac. Wireless signal exposure according to one example may be expressed as a power density (PD), which represents energy absorption per unit area. PD is W / m² 2 It may have units. PD can be used to indicate radio signal exposure for transmission frequencies, including wireless communication technologies such as IEEE 802.11ad or 5G. SAR exposure limit values ​​and PD exposure limit values ​​can be set as shown in Table 1.

[0051] Regional SAR Exposure Limit Value (W / kg) PD Exposure Limit Value (W / m²) 2 )North America (FCC) 1.610 Canada (ISED) 1.610 Japan (TELEC) 2.020 China (NAL) / (NCC) 2.020 Europe (RED) 2.010 Korea (KC) 1.610 Global (FCC or RED)--

[0052] An electronic device (100) can transmit multiple signals based on at least one wireless communication technology. In a situation where the electronic device (100) transmits multiple signals, a user of the electronic device (100) may be exposed to the electromagnetic waves of each of the multiple signals. In a situation where the electronic device (100) transmits multiple signals based on at least one wireless communication technology, the electronic device (100) must comply with a wireless signal exposure limit value. For example, in a situation where the electronic device (100) transmits signals at transmission frequencies below 6 GHz and transmission frequencies above 6 GHz, it must evaluate wireless signal exposure caused by signals at transmission frequencies below 6 GHz and transmission frequencies above 6 GHz and comply with the wireless signal exposure limit value. The SAR must be limited so that the combined value of the SAR distributions for each of the multiple frequency bands is less than the SAR exposure limit value. The SAR distribution may be normalized by the SAR exposure limit value. The PD must be limited so that the combined value of the PD distributions for each of the multiple frequency bands is less than the PD exposure limit value. The PD distribution can be normalized by the exposure limit value of PD.

[0053] The electronic device (100) may use a total exposure ratio (TER, total exposure ratio) (501) that combines the wireless signal exposures of each of the plurality of signals to evaluate and comply with the wireless signal exposure of each of the plurality of signals corresponding to at least one wireless communication technology. The TER (510) may be expressed in a combined form of the SAR distribution and the PD distribution as in Equation 1.

[0054]

[0055] In mathematical equation 1, i represents the frequency band, and SAR i represents the SAR for the i-th frequency band, and PD i represents the PD for the i-th frequency band. SARlimit and / or PD limit represents a wireless signal exposure limit value set by domestic or international regulatory bodies. TER (510) is the exposure limit value of SAR (SAR) corresponding to each frequency band. limit SAR normalized by ) ) and / or the exposure limit value of PD (PD limit PD normalized by ) It can refer to a value that combines ).

[0056] SAR of Mathematical Formula 1 i is together with T as in mathematical formula 2 SAR It can be expressed as the average value of the transmitted power over the time interval T SAR can refer to the length of the time window, which is the time interval for measuring SAR.

[0057]

[0058] PD of Mathematical Formula 1 i is as in mathematical equation 3, T PD It can be expressed as the average value of the transmitted power over the time interval T PD can refer to the length of the time window, which is the time interval for measuring PD.

[0059]

[0060] The electronic device (100) can maintain the TER (510) at 1 or less to comply with wireless signal exposure limit values ​​set by domestic or international regulatory bodies. The electronic device (100) can limit the TER (510) to satisfy Equation 4.

[0061]

[0062] According to one embodiment, the electronic device (100) is SAR i SAR limit Exceeding or PD i GaPDlimit Even if a situation occurs where it exceeds, the time-averaged SAR as in Equations 3 and 4 i and time-average PD i Because it calculates TER (510), the TER can be kept below 1, which is the maximum allowable TER. The electronic device (100) can satisfy the wireless signal exposure limit value set by the regulatory authority by keeping the TER (510) below the maximum allowable TER (e.g., 1).

[0063] FIG. 5 describes a situation in which an electronic device (100) performs non-terrestrial network communication after performing terrestrial network communication, but it should be understood that the contents of the present disclosure are not applicable only to situations in which terrestrial network communication is switched while performing non-terrestrial network communication, but can be applied to all situations in which the electronic device (100) starts a communication connection. For example, it can be applied to situations in which additional communication is performed while the electronic device performs non-terrestrial network communication and terrestrial network communication simultaneously, or to situations in which terrestrial network communication is performed after performing non-terrestrial network communication.

[0064] The electronic device (100) can perform a non-terrestrial network communication connection in response to a request for a non-terrestrial network communication connection. For example, the electronic device (100) can perform a non-terrestrial network communication connection after performing terrestrial network communication. Even when performing non-terrestrial network communication, the electronic device (100) can satisfy the wireless signal exposure limit value set by the regulatory authority by maintaining the TER (510) below the maximum allowable TER (e.g., 1). However, since the TER (510) is calculated based on the transmission power used during terrestrial network communication and non-terrestrial network communication, when performing a non-terrestrial network communication connection, the electronic device (100) needs to use only the available TER, excluding the TER calculated during the non-terrestrial network communication connection from the maximum allowable TER (e.g., 1). The TER (501) can be calculated based on the transmission power (502) while the electronic device (100) performs terrestrial network communication. For example, it can be calculated based on the time-average value of the transmission power included in the time interval of the time window (503).

[0065] The electronic device (100) may be maintained in a minimum transmission power mode after performing terrestrial network communication and before connecting to a non-terrestrial network communication. The minimum transmission power mode may refer to a mode that maintains the transmission power for performing communication at the lowest level. As time progresses, the proportion of time in the minimum transmission power mode within the time window (503), which is the time interval for measuring TER (510), may increase. Therefore, as time progresses, the TER (510) calculated may decrease as the proportion of time in which the electronic device (100) performs terrestrial network communication within the time window (503) decreases.

[0066] The electronic device (100) can perform a non-terrestrial network communication connection at a point in time (560) after a time window (503), which is a time interval measured while maintaining the lowest transmission power mode TER (510), has elapsed. The TER (510) can be determined as a value according to the TER of the lowest transmission power mode when the lowest transmission power mode is maintained for a time window (503). Since the above lowest transmission power mode is merely an example, it should be understood that the contents of the present disclosure may apply not only when the electronic device (100) of the present disclosure is in the lowest transmission power mode but also in situations where the calculated TER is reduced.

[0067] The time window (503), which is the time interval for measuring TER (510), can be determined as a time interval set by domestic or international regulatory bodies. The time window (503) can be determined as shown in Table 2.

[0068] Area SAR Time Window (Unit: sec) PD Time Window (Unit: sec) Frequency 3GHz or less Frequency Over 3GHz 6GHz or less Frequency 10GHz or less Frequency Over 3GHz North America (FCC) 10060304 Canada (ISED) 360360-- Japan (TELEC) 360360360360 China (NAL) / (NCC) 360360360360 Europe (RED) 360360-- Korea (KC) 360360360 Global (FCC or RED)----

[0069] For example, when the electronic device (100) calculates the TER (510) according to the time window (e.g., 100 seconds) (503) according to North America (FCC), it may perform a non-terrestrial network communication connection after maintaining the lowest transmission power mode for a time window (e.g., 100 seconds) (503). The TER (510) used when performing terrestrial network communication may not be reflected in the TER (510) as time window (e.g., 100 seconds) (503) elapses. Even if the electronic device (100) performs a non-terrestrial network communication connection, it may not exceed the wireless signal exposure limit value because the TER based on the power transmitted in the terrestrial network communication is not reflected. The user of the electronic device (100) may have to wait without performing non-terrestrial network communication for a time window (e.g., 100 seconds) (503) so that the electronic device (100) complies with the wireless signal exposure limit value. Waiting for a time window (e.g., 100 seconds) (503) of the electronic device (100) can cause inconvenience to the user. The electronic device (100) can cause inconvenience to the user by waiting for a time window (e.g., 100 seconds) (503) even though it can perform a non-terrestrial network communication connection after the time (550) corresponding to the TER (520) required in response to a non-terrestrial network communication connection request has elapsed. The TER (520) required in response to a non-terrestrial network communication connection request may refer to the TER required according to the transmission power of the signal in a situation where a signal is transmitted in response to a non-terrestrial network communication connection request.

[0070] An electronic device (100) according to one embodiment can check the time average TER during the time window until the point (540) when the terrestrial network communication is terminated in order to perform a non-terrestrial network communication connection. The electronic device (100) can check the (re)calculated TER (510) even while maintaining the lowest transmission power mode to perform a non-terrestrial network communication connection. The electronic device (100) can perform a non-terrestrial network communication connection from the point (550) when the time corresponding to the TER (520) required by the non-terrestrial network communication connection request has elapsed, even before a time window (e.g., 100 seconds) (503) has elapsed. From FIG. 6 onwards, it will be explained that the electronic device (100) performs a non-terrestrial network communication connection before a time window (e.g., 100 seconds) (503) has elapsed, thereby preventing the inconvenience of the user having to wait for a time window.

[0071] FIG. 6 is a drawing illustrating an electronic device according to one embodiment.

[0072] According to one embodiment, the electronic device may include a processor (e.g., the processor (110) of FIG. 1) (610), memory (620), a first communication circuit (630), and / or a second communication circuit (640). Various embodiments of this document may be implemented even if some of the illustrated configurations are omitted or substituted with other configurations. The electronic device (100) may further include at least some of the configurations and / or functions of the electronic device (100) of FIG. 1 in addition to the illustrated configurations. At least some of each of the illustrated (or unillustrated) components of the electronic device (100) may be operatively, functionally, and / or electrically connected.

[0073] The processor (610) may include an application processor (611) and / or a communication processor (e.g., CP (118) of FIG. 1) (612). The processor (610) may include at least one processing circuitry, and the processor (610) may include at least one processor (610). The operations described in FIG. 1 through FIG. 11 may be performed individually or collectively by at least one processor (e.g., application processor (611), communication processor (612)) included in the processor (610).

[0074] The processor (610) may be operatively connected to the first communication circuit (630) and / or the second communication circuit (640). The processor (610) according to one embodiment may transmit and / or receive data through a terrestrial network and / or a non-terrestrial network.

[0075] The first communication circuit (630) can be connected to a ground network through a ground wireless communication device included in the ground network (e.g., the ground wireless communication device (210) of FIG. 2). The processor (610) can control the first communication circuit (630) to transmit or receive data to or from the ground wireless communication device (210).

[0076] The second communication circuit (640) can be connected to a non-ground network through a non-ground wireless communication device included in the non-ground network (e.g., the non-ground wireless communication device (220) of FIG. 2). The processor (610) can control the second communication circuit (640) to transmit or receive data to or from the non-ground wireless communication device (220).

[0077] In one embodiment, the first communication circuit (630) can perform terrestrial network communication, and the second communication circuit (640) can perform non-terrestrial network communication. In one embodiment, the first communication circuit (630) can perform both terrestrial network communication and non-terrestrial network communication. In one embodiment, the second communication circuit (640) can be configured to perform both terrestrial network communication and non-terrestrial network communication.

[0078] The memory (620) can store at least one computer program, and at least one computer program may include instructions that can be executed by the processor (610). The operations described in FIGS. 1 through 11 can be performed according to the execution of instructions contained in the memory (620).

[0079] FIG. 7 is an operation flowchart of an application processor and a communication processor according to one embodiment.

[0080] An electronic device (e.g., the electronic device (600) of FIG. 6) can transmit and / or receive data to and from a non-terrestrial network (e.g., the non-terrestrial network system (400) of FIG. 4) through a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2).

[0081] The electronic device (600) may include a first communication circuit supporting a terrestrial network (e.g., the first communication circuit (630) of FIG. 6), a second communication circuit supporting a non-terrestrial network (e.g., the second communication circuit (640) of FIG. 6), a communication processor controlling the first communication circuit (630) or the second communication circuit (640) (e.g., the communication processor (612) of FIG. 6), an application processor (611) controlling the communication processor (612), and / or an application supporting a service using the non-terrestrial network.

[0082] The application may be an application that supports services using non-terrestrial wireless communication depending on various causes (e.g., user input to activate services via non-terrestrial wireless communication, or automatic activation of non-terrestrial wireless communication according to specific conditions). According to one example, the application may support services for transmitting and / or receiving data via non-terrestrial wireless communication, and the data may be various data including text messages, video messages, and voice messages.

[0083] The application processor (611) may receive a non-terrestrial network communication connection request in operation 710. The non-terrestrial network communication connection request may refer to a request to instruct to establish data communication through a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2).

[0084] The application may request the application processor (611) to connect to non-terrestrial network communication based on user input to activate services via non-terrestrial network communication or the satisfaction of specific conditions under which non-terrestrial network communication is automatically activated. The application may request the connection to non-terrestrial network communication by transmitting a command (e.g., a command to activate non-terrestrial wireless communication) implemented on a layer other than the application (e.g., a framework) to the application processor (611).

[0085] The application processor (611) can receive a non-terrestrial network communication connection request and forward it to the communication processor (612). In response to receiving the non-terrestrial network communication connection request, the application processor (611) can control the communication processor (612) to activate the second communication circuit (640) for data transmission and / or reception via non-terrestrial network communication.

[0086] The application processor (611) may request the communication processor (612) to check whether the TER condition for a non-terrestrial network communication connection is satisfied in operation 720. The TER condition may refer to a condition in which the available TER (e.g., the difference between the maximum allowable TER and the calculated TER) is greater than or equal to a set value (e.g., the TER required for a non-terrestrial network communication connection).

[0087] When the communication processor (612) receives a request for a non-terrestrial network communication connection, it can perform a non-terrestrial network communication connection only in a situation where Equation 4 is satisfied (e.g., a situation where the available TER is greater than or equal to the TER required for service through non-terrestrial network communication). Accordingly, the application processor (611) may request the communication processor (612) to check whether the available TER (e.g., the difference between the maximum allowable TER and the TER calculated before receiving the request for a non-terrestrial network communication connection) is greater than or equal to a set value (e.g., the TER required for a non-terrestrial network communication connection).

[0088] According to one example, the radio signal exposure limit value (e.g., SAR) used to calculate TER limit and / or PD limit ) can be established in accordance with at least one of the following regulations: North America’s FCC (Federal Communications Commission), Canada’s ISED (Innovation, Science and Economic Development Canada), Japan’s TELEC (Telecommunications Engineering Center), China’s NAR (Network Access License) (or NCC (National Communications Commission)), Europe’s RED (Radio Equipment Directive), or Korea’s KC (Korea Certification).

[0089] According to one embodiment, the application processor (611) may request the communication processor (612) to operate in a scan mode, which is a mode for scanning at least one non-ground network base station that the communication processor (612) can connect to. However, it should be understood that the communication processor (612) can scan at least one non-ground network base station that it can connect to only when the application processor (611) requests the operation in a scan mode.

[0090] The communication processor (612) can scan at least one connectable non-ground network base station in operation 730. A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes an electronic device within the coverage where the non-ground network base station can perform wireless communication.

[0091] The communication processor (612) can scan signals provided by the non-terrestrial network base station (e.g., broadcast control channel (BCCH) or synchronization signal (SS)) and determine whether the electronic device is within the coverage of the non-terrestrial network base station. If the non-terrestrial network base station is in a movable form (e.g., satellite), the non-terrestrial network base station can move continuously. Even if the communication processor (612) determines that the electronic device is within the coverage of the non-terrestrial network base station, it can periodically scan signals provided by the non-terrestrial network base station to reconfirm whether the electronic device is within the coverage of the non-terrestrial network base station.

[0092] The communication processor (612) can perform a cell scan within a non-ground network communication coverage (e.g., non-ground wireless communication coverage (325)) provided by a connectable non-ground network base station (e.g., non-ground wireless communication device (220)). As a result of performing the cell scan, the communication processor (612) can identify the cells provided by the connectable non-ground network base station (e.g., non-ground wireless communication device (220)). The communication processor (612) can identify multiple cells provided by the connectable non-ground network base station (e.g., non-ground wireless communication device (220)).

[0093] The communication processor (612) can check communication environment indicators of communication provided by at least one cell of a non-terrestrial network base station that can be connected. The communication processor (612) can check communication environment indicators based on a reference signal provided by the cell of the base station. The communication environment indicators checked by the communication processor (612) may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0094] The communication processor (612) can calculate the rate of change of the communication environment indicator of communication provided by at least one connectable non-ground network base station (or cell of the base station). If the non-ground network base station is in a movable form (e.g., satellite), the non-ground network base station can move continuously. The communication processor (612) can calculate the rate of change of the communication environment indicator by periodically checking the communication environment indicator of communication provided by at least one connectable non-ground network base station (or cell of the base station).

[0095] The communication processor (612) can scan at least one non-ground network base station (or cell of a base station) that can be connected prior to a non-ground network communication connection, and can check (or calculate) the communication environment indicator of each base station (or cell of a base station).

[0096] The communication processor (612) can check the calculated TER in operation 740. The communication processor (612) can check the calculated TER between the time of checking the TER and the time window length prior to the time window length. For example, the communication processor (612) can check the calculated TER during the time window prior to receiving the non-terrestrial network communication connection request in response to receiving the non-terrestrial network communication connection request.

[0097] The calculated TER may be determined by a signal transmitted through the first communication circuit (630) and / or the second communication circuit (640). The communication processor (612) may check the strength of the signal transmitted by the first communication circuit (630) and / or the second communication circuit (640) and calculate the TER based on the strength of the checked signal. The communication processor (612) may calculate the TER based on information related to SAR and / or PD provided by the manufacturer of the first communication circuit (630) and / or the second communication circuit (640). The communication processor (612) may request information to check the TER from an external server and receive information to calculate the TER from the external server. The communication processor (612) may receive the TER calculated by the external device from the external device.

[0098] The communication processor (612) can check whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value in operation 750.

[0099] The maximum allowable TER may refer to the maximum value of TER allowed for the electronic device. For example, the maximum allowable TER may be 1. TER is a radio signal exposure limit value (e.g., SAR) according to Equation 1. limit and / or PD limit It can be calculated as the total sum of normalized values ​​according to ).

[0100] The difference between the maximum allowable TER and the calculated TER may refer to the TER available to the electronic device. The electronic device has a radio signal exposure limit value (e.g., SAR). limit and / or PD limitIt may be configured to transmit a signal while satisfying ) (or while maintaining the TER below the maximum allowable TER (e.g., 1). The electronic device may be allowed a TER equal to the maximum allowable TER, but since the calculated TER was used, if it uses a transmit power corresponding to a TER greater than the difference between the maximum allowable TER and the calculated TER, the radio signal exposure limit value (e.g., SAR) limit and / or PD limit ) may be violated. Therefore, the communication processor (612) can determine whether a non-terrestrial network communication connection can be performed by checking whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value.

[0101] The setting value may be set based on the non-terrestrial network communication performance of the second communication circuit. The non-terrestrial network communication performance may refer to the communication performance in a situation where the second communication circuit communicates with a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2). The non-terrestrial network communication performance may include one or more of the non-terrestrial network maximum transmission power, power limit value, transmission time ratio, modulation type, or data transmission speed.

[0102] The setting value may be set according to the size of the transmitted data included in the non-terrestrial network communication connection request. The non-terrestrial network communication connection request according to operation 710 may include a request for the transmission of data based on the non-terrestrial network. The data based on the non-terrestrial network may include data necessary to perform a service through non-terrestrial network communication. For example, an application may perform a service of transmitting and / or receiving data through non-terrestrial wireless communication. The data may be various data including text messages, video messages, or voice messages.

[0103] The set value may represent the TER required to transmit transmission data included in a non-terrestrial network communication connection request. The set value may be determined based on the value obtained by multiplying the required TER per second and the signal transmission time. For example, the set value may be determined to be a value greater than or equal to the value obtained by multiplying the required TER per second and the signal transmission time.

[0104] The TER required per second may refer to the TER required per second when the second communication circuit (or the first communication circuit) performs non-terrestrial network communication. The second communication circuit according to one example may transmit data at maximum transmission power when performing non-terrestrial network communication. The TER required per second may refer to the TER required per second while the second communication circuit transmits data at maximum transmission power.

[0105] The TER required per second can be set to be proportional to the maximum transmission power. The maximum transmission power may refer to the maximum power level that the second communication circuit can transmit when performing non-terrestrial network communication. Based on the maximum transmission power, the reach of the signal transmitted by the second communication circuit and / or the quality of the signal may be determined. The maximum transmission power may have units of dBm (decibel-milliwatts).

[0106] The required TER per second can be set to be inversely proportional to the power limit value. The average power limit value may include a power limit value based on the time-averaged SAR (or PD), and a radio signal exposure limit value (e.g., SAR) which is the maximum allowable value of average power set by domestic or international regulatory authorities. limit and / or PD limit It can refer to ).

[0107] The TER required per second can be set to be proportional to the duty rate. The duty rate may refer to the ratio of the time during which the second communication circuit transmits a signal out of the total time allocated for transmission.

[0108] The TER required per second can be set to be inversely proportional to the length of the time window. The length of the time window can be determined by a value set by a domestic or international regulatory body.

[0109] Signal transmission time may refer to the time required to transmit transmission data included in a non-terrestrial network communication connection request.

[0110] The data transmission speed may refer to the speed at which data is transmitted through the second communication circuit. The data transmission speed may have units of bps (bits per second). The data transmission speed may be determined based on at least one of the non-terrestrial network communication performances of the second communication circuit. For example, if the modulation type is changed from BPSK (binary phase shift keying) to QPSK (quadrature phase shift keying), the data transmission speed may be doubled.

[0111] The processor (610) can set a value based on the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (e.g., 12 seconds). For example, the electronic device can set a value greater than the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (e.g., 12 seconds) (e.g., 0.216) as the set value (e.g., 0.220).

[0112] The communication processor (612) may wait for a specified time if, in operation 751, the difference between the maximum allowable TER and the calculated TER is less than a set value. The specified time may be a time specified by the manufacturer (e.g., 1 second). If the difference is less than the set value, the communication processor (612) may check the TER after the specified time has elapsed and recalculate the difference between the maximum allowable TER and the checked TER. The communication processor (612) may repeat the operation of checking the TER after the specified time has elapsed and the operation of checking the difference between the maximum allowable TER and the recalculated TER until the difference between the maximum allowable TER and the recalculated TER becomes greater than or equal to the set value.

[0113] The calculated TER may decrease while the communication processor (612) waits for a specified time. The communication processor (612) may wait for a specified time in the lowest transmission power mode. As time elapses, the proportion of time in the lowest transmission power mode within the time window, which is the time interval for measuring TER, may increase. Therefore, as time elapses, the calculated TER may decrease as the proportion of time in which the electronic device performs terrestrial network communication within the time window decreases.

[0114] The communication processor (612) can check the recalculated TER after waiting for a specified time and reconfirm whether the difference between the maximum allowable TER and the recalculated TER is greater than or equal to a set value.

[0115] The communication processor (612) may notify the application processor (611) that the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value in operation 760. The situation in which the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value may be a situation in which the TER does not exceed the maximum allowable TER (e.g., 1) even when transmitting data included in a non-terrestrial network communication connection request.

[0116] The application processor (611) may request the communication processor (612) to establish a non-terrestrial network communication connection in operation 770. For example, the application processor (611) may request the communication processor (612) to switch to a non-terrestrial network communication connection mode.

[0117] According to one embodiment, the application processor (611) may request the communication processor (612) to operate in a connection mode, which is a mode for communicating with at least one non-ground network base station that the communication processor (612) can connect to. However, it should be understood that the communication processor (612) can not perform a communication connection with at least one non-ground network base station only when the application processor (611) requests the operation in a connection mode.

[0118] The communication processor (612) can determine the priority of at least one non-ground network base station that can be connected in operation 780.

[0119] The communication processor (612) can scan for connectable non-ground network base stations (e.g., non-ground wireless communication devices (220)) and perform cell scanning within the non-ground network communication coverage (e.g., non-ground wireless communication coverage (325)) provided by the connectable non-ground network base station (e.g., non-ground wireless communication devices (220)) until the application processor (611) requests to perform communication with the non-ground network base station. In response to the application processor (611) requesting to perform communication with the non-ground network base station, the communication processor (612) can identify at least one connectable non-ground network base station (or cell of a base station) scanned up to the point of receiving the request.

[0120] At least some of the non-ground network base stations (or base station cells) that the communication processor (612) has identified as connectable may become unconnectable as the communication processor (612) waits for a specified time during which the difference between the maximum allowable TER and the calculated TER exceeds a set value. In response to a request from the application processor (611) to perform communication with a non-ground network base station, the communication processor (612) may identify the non-ground network base stations (or base station cells) that have become unconnectable among the connectable non-ground network base stations (or base station cells) and exclude them from the non-ground network base stations (or base station cells) identified as connectable.

[0121] The communication processor (612) determines the priority of at least one non-ground network base station (or cell of a base station) that can be connected, and if the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, it can perform a non-ground network communication connection to the non-ground network base station (or cell of a base station) with the highest priority in the determined priority. The communication processor (612) can check communication environment indicators to determine the priority.

[0122] The priority of at least one connectable non-terrestrial base station (or a cell of a base station) can be determined based on communication environment indicators for each of the at least one non-terrestrial base station. The communication environment indicators may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0123] For example, the communication processor (612) may determine the priority of a non-terrestrial network base station (or base station cell) as high as the path loss of the non-terrestrial network base station (or base station cell) is small (or RSRP is large). Since a non-terrestrial network base station (or base station cell) with small path loss (or RSRP is large) may indicate that the amount of signal transmitted (or received) by the base station is small while traveling, a non-terrestrial network base station (or base station cell) with small path loss (or RSRP is large) may indicate a base station (or cell) with strong signal strength. Since the user experience (e.g., data transmission speed, power consumption, communication stability, etc.) can be improved as the amount of signal transmitted (or received) is small when transmitting a signal with the same transmission power, the communication processor (612) may determine the priority of a non-terrestrial network base station (or base station cell) with small path loss (or RSRP is large) as high as the amount of signal lost when transmitting (or receiving) a signal is small.

[0124] For example, the communication processor (612) may determine the priority of a non-ground network base station (or base station cell) as high as the signal-to-interference-plus-noise ratio (SINR) or reference signal received quality (RSRQ) of the non-ground network base station (or base station cell). Since a non-ground network base station (or base station cell) with a high SINR or RSRQ may indicate a low ratio of noise (or interference) included in the received signal, a non-ground network base station (or base station cell) with a high SINR or RSRQ may be a non-ground network base station (or base station cell) with high signal quality. The communication processor (612) may determine the priority of a non-ground network base station (or base station cell) with high signal quality as high.

[0125] For example, the communication processor (612) can determine the priority of a non-terrestrial network base station (or cell of a base station) as high as the required transmission power, which is the power for transmitting transmission data included in a non-terrestrial network communication connection request, is small. The communication processor (612) can check the reception sensitivity of each connectable non-terrestrial network base station (or cell of a base station) and calculate the required transmission power based on the reception sensitivity and path loss.

[0126] For example, the communication processor (612) can determine the priority of non-terrestrial network base stations (or base station cells) to be higher as the transmission power headroom increases. The transmission power headroom may represent the difference between the transmission power of an electronic device and the maximum transmission power, and may refer to the range of remaining transmission power. When the transmission power headroom is large, the communication processor (612) can stably increase the transmission power even in situations where path loss increases.

[0127] When the communication processor (612) determines the priority of at least one non-terrestrial network base station (or cell of a base station) that can be connected based on communication environment indicators, it may determine an indicator for determining the priority among communication environment indicators based on the type of transmission data included in the non-terrestrial network communication connection request.

[0128] The communication processor (612) may determine the priority of at least one non-terrestrial network base station (or cell of a base station) that can be connected based on one of the communication environment indicators, as well as determine the priority based on two or more communication environment indicators. For example, when the communication processor (612) determines the priority based on two or more communication environment indicators, it may assign a weight to each of the two or more communication environment indicators and determine the priority according to the assigned weight.

[0129] The communication processor (612) can determine priority based on the rate of change of communication environment indicators provided by at least one connectable non-ground network base station (or base station cell). If the communication environment indicators of at least one connectable non-ground network base station (or base station cell) are similar, the communication processor (612) can determine the base station (or base station cell) whose communication environment indicators change in a direction that improves communication quality as the base station (or base station cell) with high priority.

[0130] The communication processor (612) can perform a non-ground network communication connection to the non-ground network base station with the highest priority in the determined priority in operation 790.

[0131] The electronic device (100) can perform a non-terrestrial network communication connection in response to the available TER (e.g., the difference between the maximum allowable TER and the calculated TER) being greater than or equal to a set value (e.g., the TER required for service through non-terrestrial network communication) even without waiting for a time window. The user of the electronic device (100) can receive a service based on non-terrestrial network communication even before a time window has elapsed, if the available TER (e.g., the difference between the maximum allowable TER and the TER calculated by the electronic device) is greater than or equal to a set value (e.g., the TER required for service through non-terrestrial network communication). The electronic device (100) of the present disclosure can prevent inconvenience caused by waiting time in situations where a user requires a non-terrestrial network communication connection.

[0132] According to one embodiment, the communication processor (612) may omit operations 780 and 790 and perform a non-ground network communication connection with one of at least one connectable non-ground network base stations in response to a request for a non-ground network communication connection from the application processor (611). For example, the communication processor (612) may scan for connectable non-ground network base stations and perform a communication connection with the first connectable non-ground network base station scanned. When the communication processor (612) is configured to establish a communication connection with the first connectable non-ground network base station scanned, the communication processor (612) may not scan for any more non-ground network base stations in response to scanning for connectable non-ground network base stations.

[0133] FIG. 8 is a diagram illustrating the operation of an electronic device determining a set value according to one embodiment.

[0134] The electronic device (100) can determine whether it can perform a non-terrestrial network communication connection by checking whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value. Since the electronic device (100) is required to limit wireless signal exposure that exceeds a wireless signal exposure limit value, it can perform a non-terrestrial network communication connection when the available TER (e.g., the difference between the maximum allowable TER and the calculated TER) is greater than or equal to a set value (e.g., the TER required for service through non-terrestrial network communication).

[0135] The setting value may be a value indicating the TER required for service through non-terrestrial network communication.

[0136] The setting value may be set based on the non-terrestrial network communication performance of the second communication circuit. The non-terrestrial network communication performance may refer to the communication performance in a situation where the second communication circuit communicates with a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2). The non-terrestrial network communication performance may include one or more of the non-terrestrial network maximum transmission power (810), average power limit value (820), transmission time ratio, modulation type, or data transmission speed.

[0137] The setting value may be configured according to the size of the transmitted data included in the non-terrestrial network communication connection request. The non-terrestrial network communication connection request may include a request for data transmission based on the non-terrestrial network. The non-terrestrial network-based data may include data necessary to perform services through non-terrestrial network communication. For example, an application may perform a service of transmitting and / or receiving data via non-terrestrial wireless communication. The data may be various types of data, including text messages, video messages, and voice messages.

[0138] The setting value may represent the TER required to transmit transmission data included in a non-terrestrial network communication connection request. The setting value may be determined based on the value obtained by multiplying the required TER per second and the signal transmission time (840). For example, the setting value may be determined to be greater than the value obtained by multiplying the required TER per second and the signal transmission time (840).

[0139] The TER required per second may refer to the TER required per second when the second communication circuit performs non-terrestrial network communication. The second communication circuit according to one example may transmit data at maximum transmission power (810) when performing non-terrestrial network communication. The TER required per second may refer to the TER required per second while the second communication circuit transmits data at maximum transmission power (810).

[0140] The TER required per second can be set to be proportional to the maximum transmission power (810). The maximum transmission power (810) may refer to the maximum power level that the second communication circuit can transmit when performing non-terrestrial network communication. Based on the maximum transmission power (810), the reach of the signal transmitted by the second communication circuit and / or the quality of the signal may be determined. The maximum transmission power (810) may have units of dBm (decibel-milliwatts).

[0141] The TER required per second can be set to be inversely proportional to the average power limit value (820). The average power limit value (820) may refer to a power limit value based on the time-averaged SAR (or PD), and is a wireless signal exposure limit value (820) that is the maximum allowable power value set by a domestic or international regulatory body (e.g., SAR limit and / or PD limit It can refer to ).

[0142] The TER required per second can be set to be proportional to the duty rate. The duty rate may refer to the ratio of the time (862) during which the second communication circuit transmits a signal to the time (861) allocated for transmission.

[0143] The TER required per second can be set to be inversely proportional to the length of the time window (850). The length of the time window (850) can be determined by a value set by a domestic or international regulatory body.

[0144] The TER required per second according to the example can be set as [Equation 5].

[0145]

[0146] For example, if the time window (850) length (e.g., 100 seconds) and the maximum transmission power (810) (e.g., 36 dBm), average power limit value (820) (e.g., 20 dBm), and transmission time ratio (e.g., 10%) of the non-terrestrial network communication performance of the second communication circuit are determined, the required TER per second (e.g., 0.018) can be determined.

[0147] The signal transmission time (840) may refer to the time required to transmit transmission data included in a non-terrestrial network communication connection request.

[0148] The data transmission speed may refer to the speed at which data is transmitted through the second communication circuit. The data transmission speed may have units of bps (bits per second). The data transmission speed may be determined based on at least one of the non-terrestrial network communication performances of the second communication circuit. For example, if the modulation type is changed from BPSK (binary phase shift keying) to QPSK (quadrature phase shift keying), the data transmission speed may be doubled.

[0149] For example, the value obtained by dividing the size of the data (e.g., 12 kbytes) by the data transmission speed (e.g., 1.2 kbps) can be determined as the signal transmission time (840) (e.g., 12 seconds).

[0150] The electronic device (100) can set a value based on the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (840) (e.g., 12 seconds). For example, the electronic device (100) can set a value greater than the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (840) (e.g., 12 seconds) (e.g., 0.216) as the set value (e.g., 0.220).

[0151] FIG. 9 is a drawing illustrating an electronic device for determining the priority of at least one connectable non-ground network base station according to one embodiment.

[0152] The electronic device (100) can scan at least one connectable non-ground network base station (base station X (910), base station Y (920), base station Z (930)). A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes the electronic device (100) within the coverage area where the non-ground network base station can perform wireless communication.

[0153] The electronic device (100) can scan for signals provided by a non-ground network base station (e.g., a broadcast control channel (BCCH) or a synchronization signal (SS)) and determine whether the electronic device (100) is within the coverage of the non-ground network base station. If the non-ground network base station is in a movable form (e.g., a satellite), the non-ground network base station can move continuously. Even if the electronic device (100) determines that the electronic device (100) is within the coverage of the non-ground network base station, it can periodically scan for signals provided by the non-ground network base station to reconfirm whether the electronic device (100) is within the coverage of the non-ground network base station.

[0154] The electronic device (100) can perform a cell scan within a non-terrestrial network communication coverage (e.g., non-terrestrial wireless communication coverage (325)) provided by a connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)). As a result of performing the cell scan, the electronic device (100) can identify the cells provided by the connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)). The electronic device (100) can identify multiple cells provided by the connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)).

[0155] The electronic device (100) can check communication environment indicators of communication provided by a cell of at least one connectable non-terrestrial network base station (910, 920, 930). The electronic device (100) can check communication environment indicators based on a reference signal provided by a cell of the base station. The communication environment indicators checked by the electronic device (100) may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0156] The electronic device (100) can calculate the rate of change of the communication environment indicator of communication provided by at least one connectable non-ground network base station (or base station cell) (910, 920, 930). If the non-ground network base station is in a movable form (e.g., satellite), the non-ground network base station can move continuously. The electronic device (100) can calculate the rate of change of the communication environment indicator by periodically checking the communication environment indicator of communication provided by at least one connectable non-ground network base station (or base station cell) (910, 920, 930).

[0157] The electronic device (100) can scan at least one non-ground network base station (or cell of a base station) (910, 920, 930) that can be connected prior to a non-ground network communication connection, and can check (or calculate) the communication environment indicator of each base station (or cell of a base station).

[0158] The electronic device (100) can scan for connectable non-ground network base stations (e.g., non-ground wireless communication devices (220)) and perform cell scanning within the non-ground network communication coverage (e.g., non-ground wireless communication coverage (325)) provided by the connectable non-ground network base stations (e.g., non-ground wireless communication devices (220)) until the electronic device (100) requests to perform communication with a non-ground network base station. In response to the electronic device (100) requesting to perform communication with a non-ground network base station, the electronic device (100) can identify at least one connectable non-ground network base station (or cell of a base station) (910, 920, 930) scanned up to the point of receiving the request.

[0159] At least some of the non-ground network base stations (or base station cells) that the electronic device (100) has identified as connectable may become unconnectable as the electronic device (100) waits for a specified time during which the difference between the maximum allowable TER and the calculated TER exceeds a set value. In response to a request for the electronic device (100) to communicate with a non-ground network base station, the electronic device (100) may identify the non-ground network base stations (or base station cells) that have become unconnectable among the connectable non-ground network base stations (or base station cells) and exclude them from the non-ground network base stations (or base station cells) identified as connectable.

[0160] The electronic device (100) determines the priority of at least one connectable non-ground network base station (or base station cell) (910, 920, 930), and if the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, it can perform a non-ground network communication connection to the non-ground network base station (or base station cell) with the highest priority in the determined priority. To determine the priority, the electronic device (100) can check communication environment indicators.

[0161] The priority of at least one connectable non-terrestrial network base station (or cell of a base station) (910, 920, 930) may be determined based on communication environment indicators for each of at least one non-terrestrial network base station. The communication environment indicators may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0162] For example, the electronic device (100) may determine the priority of a non-ground network base station (or base station cell) as high as the path loss of the non-ground network base station (or base station cell) is small (or RSRP is large). Since a non-ground network base station (or base station cell) with small path loss (or RSRP is large) may indicate that the amount of signal transmitted (or received) by the base station is small while traveling, a non-ground network base station (or base station cell) with small path loss (or RSRP is large) may indicate a base station (or cell) with strong signal strength. Since the user experience (e.g., data transmission speed, power consumption, or communication stability) can be improved as the amount of signal transmitted (or received) is small when transmitting a signal with the same transmission power, the electronic device (100) may determine the priority of a non-ground network base station (or base station cell) with small path loss (or RSRP is large) as high as the user experience (e.g., data transmission speed, power consumption, or communication stability).

[0163] For example, the electronic device (100) may determine the priority of a non-ground network base station (or base station cell) as high as the signal-to-interference-plus-noise ratio (SINR) or reference signal received quality (RSRQ) of the non-ground network base station (or base station cell). Since a non-ground network base station (or base station cell) with a high SINR or RSRQ may indicate a low ratio of noise (or interference) included in the received signal, a non-ground network base station (or base station cell) with a high SINR or RSRQ may be a non-ground network base station (or base station cell) with high signal quality. The electronic device (100) may determine the priority of a non-ground network base station (or base station cell) with high signal quality as high.

[0164] For example, the electronic device (100) can determine the priority of a non-terrestrial network base station (or cell of a base station) as high as the required transmission power, which is the power for transmitting transmission data included in a non-terrestrial network communication connection request, is small. The electronic device (100) can check the reception sensitivity of each connectable non-terrestrial network base station (or cell of a base station) and calculate the required transmission power based on the reception sensitivity and path loss.

[0165] For example, the electronic device (100) can determine the priority of non-terrestrial network base stations (or base station cells) as high as the transmission power headroom is large. The transmission power headroom may represent the difference between the transmission power and the maximum transmission power of the electronic device (100) and may refer to the range of remaining transmission power. When the transmission power headroom is large, the electronic device (100) can stably increase the transmission power even in situations where path loss increases.

[0166] When the electronic device (100) determines the priority of at least one non-terrestrial network base station (or cell of a base station) (910, 920, 930) that can be connected based on a communication environment indicator, it may determine an indicator for determining the priority among the communication environment indicators based on the type of transmission data included in the non-terrestrial network communication connection request.

[0167] The electronic device (100) may determine the priority of at least one non-terrestrial network base station (or cell of a base station) (910, 920, 930) that can be connected based on one of the communication environment indicators, as well as determine the priority based on two or more communication environment indicators. For example, when the electronic device (100) determines the priority based on two or more communication environment indicators, it may assign a weight to each of the two or more communication environment indicators and determine the priority according to the assigned weight.

[0168] The electronic device (100) can determine priority based on the rate of change of communication environment indicators provided by at least one connectable non-ground network base station (or base station cell) (910, 920, 930). If the communication environment indicators of at least one connectable non-ground network base station (or base station cell) (910, 920, 930) are similar, the electronic device (100) can determine the base station (or base station cell) whose communication environment indicators change in a direction that improves communication quality as the base station (or base station cell) with high priority.

[0169] [Table 3] is a communication environment indicator of a connectable non-terrestrial network base station (e.g., base station X (910), base station Y (920), base station Z (930)) scanned by an electronic device (100) according to one example. Since [Table 3] is merely an example, the base stations scanned by the electronic device (100) and the communication environment indicators verified by the electronic device (100) are not limited to the contents included in [Table 3]. For example, the electronic device (100) can scan not only base stations but also cell units of base stations and can verify communication environment indicators not included in [Table 3].

[0170] Base Station (Frequency Band) Base Station X (1.5GHz) Base Station Y (1.5GHz) Base Station Z (2.1GHz) Path Loss -90dBm -92dBm -92dBm SINR 2dB 0dB 5dB Required Transmit Power 23dBm 25dBm 27dBm Transmit Power Headroom 2dB 0dB 8dB

[0171] For example, the electronic device (100) can determine the priority of the base station Z with the highest SINR as a high priority. As another example, the electronic device (100) can determine the priority of the base station Z with the largest transmit power headroom as a high priority. The electronic device (100) can perform a non-terrestrial network communication connection to the non-terrestrial network base station with the highest priority in the determined priority order.

[0172] FIG. 10 is an operation flowchart of a communication processor according to one embodiment.

[0173] The communication processor (612) can scan at least one non-ground network base station that is connectable in operation 1010. A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes an electronic device (100) within the coverage where the non-ground network base station can perform wireless communication.

[0174] The communication processor (612) can scan at least one connectable non-ground network base station in response to the application processor (611) receiving a non-ground network communication connection request and transmitting it to the communication processor (612). The non-ground network communication connection request may refer to a request instructing to establish data communication through a non-ground wireless communication device (e.g., the non-ground wireless communication device (220) of FIG. 2). The operation of the communication processor (612) scanning at least one connectable non-ground network base station is described in FIG. 9, and details are omitted in FIG. 10.

[0175] The communication processor (612) can check the TER calculated in operation 1020.

[0176] The communication processor (612) can check the calculated TER in response to the application processor (611) receiving a non-terrestrial network communication connection request and transmitting it to the communication processor (612).

[0177] The calculated TER may be determined by a signal transmitted through the first communication circuit and / or the second communication circuit. The communication processor (612) may check the strength of the signal transmitted by the first communication circuit and / or the second communication circuit and calculate the TER based on the strength of the checked signal. The communication processor (612) may calculate the TER based on information related to SAR and / or PD provided by the manufacturer of the first communication circuit and / or the second communication circuit. The communication processor (612) may request information to an external server to check the calculated TER and receive information to check the calculated TER from the external server to calculate the TER.

[0178] The communication processor (612) can check whether the difference between the maximum allowable TER and the calculated TER in operation 1030 is greater than or equal to the set value.

[0179] The maximum allowable TER may refer to the maximum value of TER allowed for the electronic device (100). For example, the maximum allowable TER may be 1. TER is a wireless signal exposure limit value (e.g., SAR) according to Equation 1. limit and / or PD limit The difference between the maximum allowable TER and the calculated TER can be calculated as the sum of values ​​normalized according to ). The difference between the maximum allowable TER and the calculated TER may refer to the TER available to the electronic device (100). The electronic device (100) has a wireless signal exposure limit value (e.g., SAR limit and / or PD limit The electronic device (100) may be configured to transmit a signal while satisfying (or while maintaining the TER below the maximum allowable TER (e.g., 1). The electronic device (100) may allow a TER equal to the maximum allowable TER, but when using a transmission power corresponding to a TER greater than the difference between the maximum allowable TER and the calculated TER because the calculated TER was used, the wireless signal exposure limit value (e.g., SAR) limit and / or PD limit) may be violated. Therefore, the communication processor (612) can determine whether a non-terrestrial network communication connection can be performed by checking whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value. The details regarding the set value are as described in FIG. 8, and are omitted in FIG. 10.

[0180] The communication processor (612) may wait for a specified time if the difference between the maximum allowable TER and the calculated TER in operation 1031 is less than a set value. The specified time may be a time specified by the manufacturer (e.g., 1 second). If the difference is less than the set value, the communication processor (612) may recalculate the TER after the specified time has elapsed and check the difference between the maximum allowable TER and the recalculated TER. The communication processor (612) may repeat the operation of recalculating the TER after the specified time has elapsed and the operation of checking the difference between the maximum allowable TER and the recalculated TER until the difference between the maximum allowable TER and the recalculated TER becomes greater than or equal to the set value.

[0181] The communication processor (612) can determine the priority of at least one non-ground network base station that can be connected in operation 1040.

[0182] The communication processor (612) can scan for connectable non-ground network base stations (e.g., non-ground wireless communication devices (220)) and perform cell scanning within the non-ground network communication coverage (e.g., non-ground wireless communication coverage (325)) provided by the connectable non-ground network base station (e.g., non-ground wireless communication devices (220)) until the application processor (611) requests to perform communication with the non-ground network base station. In response to the application processor (611) requesting to perform communication with the non-ground network base station, the communication processor (612) can identify at least one connectable non-ground network base station (or cell of a base station) scanned up to the point of receiving the request.

[0183] The communication processor (612) determines the priority of at least one non-ground network base station (or cell of a base station) that can be connected, and if the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, it can perform a non-ground network communication connection to the non-ground network base station (or cell of a base station) with the highest priority in the determined priority. To determine the priority, the communication processor (612) can check the communication environment indicators.

[0184] The priority of at least one connectable non-terrestrial base station (or cell of a base station) can be determined based on communication environment indicators for each of at least one non-terrestrial base station. The communication environment indicators may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom. The operation of the communication processor (612) determining the priority of at least one connectable non-terrestrial base station is described in FIG. 9, and details are omitted in FIG. 10.

[0185] The communication processor (612) can perform a non-ground network communication connection to the non-ground network base station with the highest priority in the determined priority in operation 1050.

[0186] According to one embodiment, the communication processor (612) may omit operations 1040 and 1050 and perform a non-ground network communication connection with one of at least one connectable non-ground network base stations in response to a non-ground network communication connection request from the application processor (611). For example, the communication processor (612) may scan for connectable non-ground network base stations and perform a communication connection with the first connectable non-ground network base station scanned. When the communication processor (612) is configured to establish a communication connection with the first connectable non-ground network base station scanned, the communication processor (612) may not scan for any more non-ground network base stations in response to scanning for connectable non-ground network base stations.

[0187] FIG. 11 is a flowchart of the operation of an electronic device according to one embodiment.

[0188] The electronic device may scan for at least one connectable non-ground network base station in response to a request for a non-ground network communication connection in operation 1110. A non-ground network base station may refer to an entity that provides various forms of non-ground network communication services. For example, a non-ground network base station may be an entity that is not fixed to the ground (e.g., a non-ground wireless communication device (220)). A connectable non-ground network base station may refer to a base station that includes an electronic device within the coverage where the non-ground network base station can perform wireless communication.

[0189] The electronic device may receive a request for a non-terrestrial network communication connection. A request for a non-terrestrial network communication connection may refer to a request instructing a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2) to establish data communication.

[0190] An application may request an application processor to connect to non-terrestrial network communication based on user input to enable services via non-terrestrial network communication or the satisfaction of specific conditions under which non-terrestrial network communication is automatically enabled. The application may request the connection to non-terrestrial network communication by transmitting a command (e.g., a command to enable non-terrestrial wireless communication) implemented on a layer different from the application (e.g., a framework) to the application processor.

[0191] In response to receiving a request for a non-terrestrial network communication connection, the electronic device may activate a second communication circuit for data transmission and / or reception via non-terrestrial network communication.

[0192] An electronic device can scan signals provided by a non-terrestrial base station (e.g., broadcast control channel (BCCH) or synchronization signal (SS)) and determine whether the electronic device is within the coverage of the non-terrestrial base station. If the non-terrestrial base station is mobile (e.g., satellite), the non-terrestrial base station may move continuously. Even if the electronic device confirms that it is within the coverage of the non-terrestrial base station, it may periodically scan signals provided by the non-terrestrial base station to reconfirm whether the electronic device is within the coverage of the non-terrestrial base station.

[0193] The electronic device can perform a cell scan within a non-terrestrial network communication coverage (e.g., non-terrestrial wireless communication coverage (325)) provided by a connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)). As a result of performing the cell scan, the electronic device can identify cells provided by the connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)). The electronic device can identify multiple cells provided by the connectable non-terrestrial network base station (e.g., non-terrestrial wireless communication device (220)).

[0194] The electronic device can determine communication environment indicators of communication provided by a cell of at least one connectable non-terrestrial network base station. The electronic device can determine communication environment indicators based on a reference signal provided by the cell of the base station. The communication environment indicators determined by the electronic device may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0195] The electronic device can calculate the rate of change of communication environment indicators of communication provided by at least one connectable non-terrestrial network base station (or base station cell). If the non-terrestrial network base station is in a mobile form (e.g., satellite), the non-terrestrial network base station can move continuously. The electronic device can calculate the rate of change of communication environment indicators by periodically checking the communication environment indicators of communication provided by at least one connectable non-terrestrial network base station (or base station cell).

[0196] The electronic device can scan at least one non-terrestrial network base station (or cell of a base station) that can be connected prior to a non-terrestrial network communication connection, and can verify (or calculate) the communication environment indicators of each base station (or cell of a base station).

[0197] The electronic device can check the total exposure ratio (TER) calculated prior to receiving a request for a non-terrestrial network communication connection in operation 1120.

[0198] The electronic device can check the TER calculated during the time window from the time of checking the TER until the time window prior. For example, the electronic device can check the TER calculated during the time window prior to receiving the non-terrestrial network communication connection request in response to receiving the non-terrestrial network communication connection request.

[0199] The electronic device can check the difference between the maximum allowable TER and the verified TER in operation 1130.

[0200] The maximum allowable TER may refer to the maximum value of TER permitted for an electronic device. For example, the maximum allowable TER may be determined to be 1. TER is a radio signal exposure limit value (e.g., SAR) according to Equation 1. limit and / or PD limit It can be calculated as the total sum of normalized values ​​according to ).

[0201] The difference between the maximum allowable TER and the calculated TER may refer to the TER available to the electronic device. The electronic device has a radio signal exposure limit value (e.g., SAR). limit and / or PD limit A signal may be transmitted while satisfying ) (or while maintaining the TER below the maximum allowable TER (e.g., 1). Although the electronic device may be allowed a TER equal to the maximum allowable TER, if it uses a transmit power corresponding to a TER greater than the difference between the maximum allowable TER and the calculated TER because the calculated TER was used, the radio signal exposure limit value (e.g., SAR) limit and / or PD limit It may violate the above. Therefore, the electronic device can determine whether it can perform a non-terrestrial network communication connection by checking whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value.

[0202] The electronic device can perform a non-terrestrial network communication connection with at least one of the scanned connectable non-terrestrial network base stations when the difference value in operation 1140 is greater than or equal to the set value.

[0203] The setting value may be set based on the non-terrestrial network communication performance of the second communication circuit. The non-terrestrial network communication performance may refer to the communication performance in a situation where the second communication circuit communicates with a non-terrestrial wireless communication device (e.g., the non-terrestrial wireless communication device (220) of FIG. 2). The non-terrestrial network communication performance may include one or more of the non-terrestrial network maximum transmission power, power limit value, transmission time ratio, modulation type, or data transmission speed.

[0204] The setting value may be set according to the size of the transmitted data included in the non-terrestrial network communication connection request. The non-terrestrial network communication connection request of operation 1110 may include a request for the transmission of data based on a non-terrestrial network. The data based on a non-terrestrial network may include data necessary to perform a service through non-terrestrial network communication. For example, an application may perform a service of transmitting and / or receiving data via non-terrestrial wireless communication. The data may be various data including text messages, video messages, or voice messages.

[0205] The setting value may represent the TER required to transmit transmission data included in a non-terrestrial network communication connection request. The setting value may be determined based on the value obtained by multiplying the required TER per second and the signal transmission time (840). For example, the setting value may be determined to be greater than the value obtained by multiplying the required TER per second and the signal transmission time (840).

[0206] The TER required per second may refer to the TER required per second when the second communication circuit performs non-terrestrial network communication. The second communication circuit according to one example may transmit data at maximum transmission power when performing non-terrestrial network communication. The TER required per second may refer to the TER required per second while the second communication circuit transmits data at maximum transmission power.

[0207] The TER required per second can be set to be proportional to the maximum transmission power. The maximum transmission power may refer to the maximum power level that the second communication circuit can transmit when performing non-terrestrial network communication. Based on the maximum transmission power, the reach of the signal transmitted by the second communication circuit and / or the quality of the signal may be determined. The maximum transmission power may have units of dBm (decibel-milliwatts).

[0208] The required TER per second can be set to be inversely proportional to the power limit value. The power limit value may include a power limit value based on the time-averaged SAR (or PD), and a radio signal exposure limit value (e.g., SAR) which is the maximum allowable power value set by a domestic or international regulatory body. limit and / or PD limit It can refer to ).

[0209] The TER required per second can be set to be proportional to the duty rate. The duty rate may refer to the ratio of the time during which the second communication circuit transmits a signal out of the total time allocated for transmission.

[0210] The TER required per second can be set to be inversely proportional to the length of the time window. The length of the time window can be determined by a value set by a domestic or international regulatory body.

[0211] Signal transmission time may refer to the time required to transmit transmission data included in a non-terrestrial network communication connection request.

[0212] The data transmission speed may refer to the speed at which data is transmitted through the second communication circuit. The data transmission speed may have units of bps (bits per second). The data transmission speed may be determined based on at least one of the non-terrestrial network communication performances of the second communication circuit. For example, if the modulation type is changed from BPSK (binary phase shift keying) to QPSK (quadrature phase shift keying), the data transmission speed may be doubled.

[0213] The electronic device may set a value based on the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (840) (e.g., 12 seconds). For example, the electronic device may set a value greater than the value obtained by multiplying the required TER per second (e.g., 0.018) and the signal transmission time (840) (e.g., 12 seconds) (e.g., 0.216) as the set value (e.g., 0.220).

[0214] The electronic device may wait for a specified time if the difference between the maximum allowable TER and the calculated TER is less than a set value. The specified time may be a time specified by the manufacturer (e.g., 1 second). If the difference is less than the set value, the electronic device may recalculate the TER after the specified time has elapsed and check the difference between the maximum allowable TER and the recalculated TER. The electronic device may repeat the operation of checking the TER after the specified time has elapsed and the operation of checking the difference between the maximum allowable TER and the recalculated TER until the difference between the maximum allowable TER and the recalculated TER becomes greater than or equal to the set value.

[0215] The calculated TER may decrease while the electronic device waits for a specified time. The electronic device may wait for a specified time in the lowest transmission power mode. As time elapses, the proportion of time spent in the lowest transmission power mode within the time window, which is the time interval for measuring TER, may increase. Therefore, as time elapses, the calculated TER may decrease as the proportion of time spent by the electronic device performing terrestrial network communication within the time window decreases.

[0216] After waiting for a specified time, the electronic device can reconfirm the calculated TER and reconfirm whether the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value.

[0217] A situation in which the difference between the maximum allowable TER and the calculated TER is greater than or equal to the set value may be a situation in which the TER does not exceed the maximum allowable TER (e.g., 1) even if transmission data included in a non-terrestrial network communication connection request is transmitted.

[0218] The electronic device can determine the priority of at least one non-terrestrial base station that can be connected.

[0219] The electronic device may scan for connectable non-terrestrial network base stations (e.g., non-terrestrial wireless communication devices (220)) until it confirms that the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, and may perform cell scanning within the non-terrestrial network communication coverage (e.g., non-terrestrial wireless communication coverage (325)) provided by the connectable non-terrestrial network base stations (e.g., non-terrestrial wireless communication devices (220)). In response to confirming that the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, the electronic device may identify at least one connectable non-terrestrial network base station (or cell of a base station) scanned up to the point of receiving the request.

[0220] At least some of the non-terrestrial network base stations (or base station cells) that the electronic device has identified as connectable may become unconnectable as the electronic device waits for a specified time for the difference between the maximum allowable TER and the calculated TER to exceed a set value. In response to the electronic device confirming that the difference between the maximum allowable TER and the calculated TER exceeds a set value, the electronic device may identify the non-terrestrial network base stations (or base station cells) among the connectable non-terrestrial network base stations (or base station cells) that have become unconnectable and exclude them from the non-terrestrial network base stations (or base station cells) identified as connectable.

[0221] The electronic device determines the priority of at least one connectable non-terrestrial network base station (or base station cell), and if the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, it may perform a non-terrestrial network communication connection to the non-terrestrial network base station (or base station cell) with the highest priority among the determined priorities. To determine the priority, the electronic device may check communication environment indicators.

[0222] The priority of at least one connectable non-terrestrial base station (or a cell of a base station) can be determined based on communication environment indicators for each of the at least one non-terrestrial base station. The communication environment indicators may include at least one of path loss, reference signals received power (RSRP), signal-to-interference-plus-noise ratio (SINR), reference signal received quality (RSRQ), required transmit power, or transmit power headroom.

[0223] For example, an electronic device may determine a higher priority for a non-terrestrial base station (or base station cell) as the path loss of the non-terrestrial base station (or base station cell) decreases (or the RSRP increases). Since a non-terrestrial base station (or base station cell) with low path loss (or high RSRP) indicates that the amount of signal transmitted (or received) by the base station is lost while traveling, a non-terrestrial base station (or base station cell) with low path loss (or high RSRP) may indicate a base station (or cell) with strong signal strength. Since a user experience (e.g., data transmission speed, power consumption, or communication stability) can be improved as the amount of transmitted (or received) signal loss decreases when transmitting a signal with the same transmission power, the electronic device may determine a higher priority for a non-terrestrial base station (or base station cell) with low path loss (or high RSRP).

[0224] For example, an electronic device may determine a higher priority for a non-terrestrial base station (or base station cell) as the signal-to-interference-plus-noise ratio (SINR) or reference signal received quality (RSRQ) of the non-terrestrial base station (or base station cell) increases. Since a non-terrestrial base station (or base station cell) with a high SINR or RSRQ may indicate a low proportion of noise (or interference) contained in the received signal, a non-terrestrial base station (or base station cell) with a high SINR or RSRQ may be a non-terrestrial base station (or base station cell) with high signal quality. The electronic device may determine a higher priority for a non-terrestrial base station (or base station cell) with high signal quality.

[0225] For example, the electronic device can determine the priority of a non-terrestrial network base station (or base station cell) as high as the required transmission power, which is the power for transmitting transmission data included in a non-terrestrial network communication connection request, is small. The electronic device can check the reception sensitivity of each connectable non-terrestrial network base station (or base station cell) and calculate the required transmission power based on the reception sensitivity and path loss.

[0226] For example, an electronic device can determine a higher priority for non-terrestrial base stations (or base station cells) as the transmit power headroom increases. Transmit power headroom can represent the difference between the electronic device's transmit power and maximum transmit power, and can refer to the range of remaining transmit power. When the transmit power headroom is large, the electronic device can stably increase transmit power even in situations where path loss increases.

[0227] When an electronic device determines the priority of at least one non-terrestrial network base station (or cell of a base station) that can be connected based on communication environment indicators, it may determine an indicator for determining the priority among communication environment indicators based on the type of transmission data included in a non-terrestrial network communication connection request.

[0228] The electronic device may determine the priority of at least one connectable non-terrestrial network base station (or base station cell) based on one of the communication environment indicators, as well as determine the priority based on two or more communication environment indicators. For example, when the electronic device determines the priority based on two or more communication environment indicators, it may assign a weight to each of the two or more communication environment indicators and determine the priority according to the assigned weight.

[0229] The electronic device can determine priority based on the rate of change of communication environment indicators provided by at least one connectable non-terrestrial network base station (or base station cell). If the communication environment indicators of at least one connectable non-terrestrial network base station (or base station cell) are similar, the electronic device can determine the base station (or base station cell) whose communication environment indicators change in a direction that improves communication quality as the base station (or base station cell) with high priority.

[0230] The electronic device can establish a non-terrestrial network communication connection with the non-terrestrial network base station that has the highest priority according to the determined priority.

[0231] According to one embodiment, the electronic device may omit the operation of determining the priority of at least one connectable non-ground network base station and, in response to confirming that the difference between the maximum allowable TER and the calculated TER is greater than or equal to a set value, perform a non-ground network communication connection with one of the at least one connectable non-ground network base stations. For example, the electronic device may scan for connectable non-ground network base stations and perform a communication connection with the first connectable non-ground network base station scanned. When the electronic device is configured to establish a communication connection with the first connectable non-ground network base station scanned, the electronic device may not scan for any more non-ground network base stations in response to scanning for connectable non-ground network base stations.
