Description

[Technical Field]

[0001] The present disclosure relates to an electronic device and a method of operating an electronic device, and relates to an electronic device supporting a non-terrestrial network. [Background technology]

[0002] Efforts are underway to develop improved 5G or pre-5G communication systems to meet the ever-increasing demand for wireless data traffic since the commercialization of 4G communication systems. For this reason, 5G or pre-5G communication systems are also referred to as beyond-4G network (Beyond 4G Network) or post-LTE (Post-LTE) systems. To achieve high data rates, 5G communication systems are being considered for implementation in ultra-high frequency (mmWave) bands (e.g., bands above 6 GHz) in addition to the bands used by LTE (bands below 6 GHz). Technologies being discussed for 5G communication systems include beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antennas.

[0003] Recently, 5G communication systems have been considering providing communication services using entities that are not fixed on the ground, in addition to base stations that are fixed on the ground. According to one embodiment, the 5G communication system considers the implementation of cellular communication using satellites. An electronic device can perform cellular communication using satellites when it is difficult to connect to a base station. Due to the characteristics of satellites that move in Earth orbit, cellular communication using satellites can implement wider coverage than cellular communication using base stations. Satellite-based cellular communication has attracted attention because it reduces shadow areas where communication services are not possible.

[0004] However, satellite-based cellular communications have lower transmission and / or reception speeds than base station-based cellular communications, and are only used to provide limited services (e.g., short message service (SMS) or voice calls). Summary of the Invention [Problem to be solved by the invention]

[0005] The electronic device may attempt to search for a non-terrestrial network that uses satellites for data communication, and may attempt to connect to the searched non-terrestrial network, and once the connection is established, the electronic device may transmit and / or receive data using satellites.

[0006] If the distance between the electronic device and the satellite is large, the path loss of the data transmission or reception path between the electronic device and the satellite may be large, and the time it takes for the electronic device to transmit or receive data may increase.

[0007] Furthermore, since the strength of the signal output by the electronic device is limited, the transmission data rate of the electronic device may be low. Therefore, communication services using non-terrestrial networks may be used within a limited range. According to one example, a non-terrestrial network providing satellite-based communication services may only provide certain services (e.g., short messaging service (SMS) and multimedia messaging service (MMS)) and may not provide other services (e.g., transmission and / or reception of user data).

[0008] An electronic device can transmit a signal to a network using a satellite to request a specific service (e.g., transmission of user data) (e.g., requesting the establishment of a packet data unit (PDU) session for transmitting user data). If the network cannot provide the specific service, it can transmit a reject message to the electronic device using the satellite in response to the request signal. Due to the relatively long distance between the electronic device and the satellite, it can take a considerable amount of time for the electronic device to receive the reject message, which can result in unnecessary power consumption and / or delays until the reject message is received.

[0009] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the present invention pertains from the following description. [Means for solving the problem]

[0010] According to an embodiment, an electronic device may include a communication circuit for supporting cellular communication using a terrestrial network and a non-terrestrial network. The electronic device may include a memory for storing mapping data in which identification information of the non-terrestrial network and services supported by the non-terrestrial network are mapped. The electronic device may include a communication processor. While connecting to a network via a node, the communication processor may determine whether a network including the node is the non-terrestrial network based on system information received from the node. If the network is the non-terrestrial network, the communication processor may determine services supported by the network based on the mapping data. The communication processor may be configured to prohibit an operation of transmitting a packet data unit (PDU) session establishment request message to the network for a service not supported by the network.

[0011] According to an embodiment, a method for operating an electronic device may include, while connecting to a network via a node, determining whether a network including the node is the non-terrestrial network based on system information received from the node. Based on the determination that the network is the non-terrestrial network, the method may include determining services supported by the network based on mapping data in which identification information of the non-terrestrial network and services supported by the non-terrestrial network are mapped. The method for operating an electronic device may include prohibiting an operation of transmitting a packet data unit (PDU) session establishment request message to the network for a service not supported by the network. [Effects of the Invention]

[0012] An electronic device and an operating method of an electronic device according to an embodiment can check services supported by a non-terrestrial network and prohibit an operation of transmitting a PDU session establishment request message to a network for a service not supported by the non-terrestrial network. Therefore, by not transmitting a message to a network requesting establishment of a PDU session for a service not supported by the non-terrestrial network, the electronic device can reduce unnecessary resource consumption or delay time due to reception of a reject message that occurs when transmitting a signal requesting establishment of a PDU session for a service not supported by the non-terrestrial network.

[0013] According to an embodiment, an electronic device and an operating method thereof can receive a UE capability request message from a network and transmit UE capability information excluding information not related to the network to the network. By excluding information not related to the network, the electronic device can reduce the size of the UE capability information, thereby reducing the time (or delay) required to transmit the UE capability information.

[0014] The effects obtained from the present invention are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those having ordinary skill in the art to which the present disclosure pertains from the following description.

Referring to FIG. 1 , in the network environment 100, the electronic device 101 can communicate with an electronic device 102 over a first network 198 (e.g., a short-range wireless communication network) or with at least one of an electronic device 104 and a server 108 over a second network 199 (e.g., a long-range wireless communication network). According to one embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. According to one embodiment, the electronic device 101 can include a processor 120, a memory 130, an input module 150, an acoustic output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identity module 196, or an antenna module 197. In some embodiments, electronic device 101 may omit at least one of these components (e.g., connection terminal 178) or may include one or more additional components. In some embodiments, some of these components (e.g., sensor module 176, camera module 180, or antenna module 197) may be integrated into a single component (e.g., display module 160).

[0026] The processor 120 may, for example, execute software (e.g., program 140), control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled to the processor 120, and perform various data processing or calculations. According to one embodiment, as at least a part of the data processing or calculations, the processor 120 may store instructions or data received from other components (e.g., the sensor module 176 or the communication module 190) in the volatile memory 132, process the instructions or data stored in the volatile memory 132, and store the resulting data in the non-volatile memory 134.

For example, if electronic device 101 includes main processor 121 and auxiliary processor 123, auxiliary processor 123 may be configured to use less power or to specialize in a designated function compared to main processor 121. Auxiliary processor 123 may be embodied separately from main processor 121 or as part of main processor 121.

[0027] The auxiliary processor 123 may control at least a portion of the functions or states associated with at least one of the components of the electronic device 101 (e.g., the display module 160, the sensor module 176, or the communication module 190), for example, instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state, or together with the main processor 121 while the main processor 121 is in an active (e.g., application execution) state. According to one embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be embodied as part of another functionally related component (e.g., the camera module 180 or the communication module 190).

The artificial intelligence models may be generated by machine learning. Such learning may be performed, for example, solely by the electronic device 101 on which the artificial intelligence models are executed, or by a separate server (e.g., the server 108). The learning algorithm may include, but is not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. The artificial intelligence model may include multiple artificial neural network layers.

[0028] The memory 130 may store various data used by at least one component (e.g., the processor 120 or the sensor module 176) of the electronic device 101. The data may include, for example, input data or output data for software (e.g., the program 140) and associated instructions. The memory 130 may include a volatile memory 132 or a non-volatile memory 134.

[0029] The program 140 may be stored as software in the memory 130 and may include, for example, an operating system 142 , middleware 144 , or an application 146 .

[0030] Input module 150 can receive instructions or data from outside (e.g., a user) electronic device 101 for use in components (e.g., processor 120) of electronic device 101. Input module 150 may include, for example, a microphone, a mouse, a keyboard, keys (e.g., buttons), or a digital pen (e.g., a stylus pen).

[0031] The audio output module 155 can output audio signals outside the electronic device 101. The audio output module 155 may include, for example, a speaker or a receiver. The speaker may be used for general purposes such as multimedia playback or audio playback. The receiver may be used to receive incoming calls. According to one embodiment, the receiver may be embodied separately from or as part of the speaker.

[0032] The display module 160 can visually provide information to an external device (e.g., a user) outside the electronic device 101. The display module 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling the device. According to one embodiment, the display module 160 may include a touch sensor configured to sense a touch or a pressure sensor configured to measure the strength of a force generated by the touch.

[0033] The audio module 170 can convert sound into an electrical signal or vice versa. According to one embodiment, the audio module 170 can receive sound via the input module 150 or output sound from the audio output module 155 or an external electronic device (e.g., the electronic device 102) (e.g., a speaker or headphones) directly or wirelessly coupled to the electronic device 101.

[0034] The sensor module 176 may sense an operating state (e.g., power or temperature) of the electronic device 101 or an external environmental state (e.g., a user state) and generate an electrical signal or data value corresponding to the sensed state. According to one embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0035] Interface 177 may support one or more specified protocols that allow electronic device 101 to directly or wirelessly interface with an external electronic device (e.g., electronic device 102). According to one embodiment, interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0036] The connection terminal 178 may include a connector through which the electronic device 101 may be physically connected to an external electronic device (e.g., the electronic device 102). According to one embodiment, the connection terminal 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

According to one embodiment, haptic module 179 can include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0038] Camera module 180 is capable of capturing still and video images and may include one or more lenses, an image sensor, an image signal processor, or a flash, according to one embodiment.

[0039] The power management module 188 may manage the power supplied to the electronic device 101. According to one embodiment, the power management module 188 may be embodied, for example, as at least part of a power management integrated circuit (PMIC).

[0040] Battery 189 may provide power to at least one component of electronic device 101. According to one embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0041] Communications module 190 can facilitate establishing a direct (e.g., wired) or wireless communication channel between electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108) and performing communication over the established communication channel. Communications module 190 may include one or more communications processors that operate independently of processor 120 (e.g., an application processor) and facilitate the direct (e.g., wired) or wireless communication. According to one embodiment, communications module 190 may include wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or wired communication module 194 (e.g., a local area network (LAN) communication module, or a power line communication module). The appropriate one of the communication modules can communicate with an external electronic device 104 through a first network 198 (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network 199 (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various communication modules can be integrated into one component (e.g., a single chip) or embodied as separate components (e.g., multiple chips). The wireless communication module 192 can use subscriber information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the subscriber identity module 196 to identify or authenticate the electronic device 101 within a communication network such as the first network 198 or the second network 199.

[0042] The wireless communication module 192 may support a 5G network after the 4G network and next-generation communication technologies, such as new radio access (NR) technology. NR technology may support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimizing terminal power and connecting multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module 192 may support, for example, a high frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module 192 may support various technologies for ensuring performance in a high frequency band, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antenna, analog beamforming, or large scale antenna. The wireless communication module 192 can support various requirements specified by the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to one embodiment, the wireless communication module 192 can support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, a loss coverage (e.g., 164 dB or less) for implementing mMTC, or a user plane latency (U-plane latency) for implementing URLLC (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less round trip).

[0043] The antenna module 197 can transmit or receive signals or power to or from an external device (e.g., an external electronic device). According to one embodiment, the antenna module 197 may include an antenna including a radiator including a conductor or a conductive pattern formed on a substrate (e.g., a PCB). According to one embodiment, the antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network such as the first network 198 or the second network 199 may be selected from the multiple antennas by, for example, the communication module 190. Signals or power may be transmitted or received between the communication module 190 and an external electronic device via the selected at least one antenna. According to one embodiment, other components (e.g., a radio frequency integrated circuit (RFIC)) in addition to the radiator may also be formed as part of the antenna module 197.

[0044] According to various embodiments, antenna module 197 may form an mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., an mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent to a second side (e.g., a top or side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0045] At least some of these components are connected to each other by a peripheral communication method (e.g., a bus, a general purpose input and output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)), and can exchange signals (e.g., commands or data) between them.

[0046] According to one embodiment, commands or data may be transmitted or received between electronic device 101 and external electronic device 104 via server 108 coupled to second network 199. Each of external electronic devices (102 or 104) may be the same or a different type of device as electronic device 101. According to one embodiment, all or part of the operations performed in electronic device 101 may be performed in one or more of external electronic devices 102, 104, and 108. For example, if electronic device 101 must perform a certain function or service automatically or in response to a request from a user or another device, electronic device 101 may request one or more external electronic devices to perform at least part of the function or service instead of or in addition to performing the function or service itself. The one or more external electronic devices that receive the request may perform at least part of the requested function or service, or additional functions or services related to the request, and communicate the results of the execution to electronic device 101. The electronic device 101 may provide the result as at least a part of a response to the request, either directly or after further processing. For example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used for this purpose. The electronic device 101 may provide an ultra-low latency service using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device 104 may include an Internet of Things (IoT) device. The server 108 may be an intelligent server using machine learning and / or neural networks. According to one embodiment, the external electronic device 104 or the server 108 may be included in a second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology and IoT-related technologies.

[0047] FIG. 2 is a block diagram 200 of an electronic device 101 for supporting legacy network communication and 5G network communication according to various embodiments. Referring to FIG. 2 , the electronic device 101 may include a first communication processor 212, a second communication processor 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, and an antenna 248.

According to other embodiments, the fourth RFIC 228 may be omitted or may be included as part of the third RFIC 226.

[0048] The first communication processor 212 can support establishment of a communication channel in a band used for wireless communication with the first network 292 and legacy network communication via the established communication channel. According to various embodiments, the first network can be a legacy network including a second generation (2G), 3G, 4G, or LTE (long term evolution) network. The second communication processor 214 can support establishment of a communication channel corresponding to a designated band (e.g., approximately 6 GHz to approximately 60 GHz) of the band used for wireless communication with the second network 294 and 5G network communication via the established communication channel. According to various embodiments, the second network 294 can be a 5G network as defined by 3GPP (registered trademark). Furthermore, according to one embodiment, the first communication processor 212 or the second communication processor 214 can support establishment of a communication channel corresponding to another designated band (e.g., approximately 6 GHz or less) of the band used for wireless communication with the second network 294 and 5G network communication via the established communication channel. According to one embodiment, the first communication processor 212 and the second communication processor 214 may be embodied in a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 may be formed in a single chip or a single package with the processor 120, the auxiliary processor 123, or the communication module 190.

[0049] During transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal of approximately 700 MHz to approximately 3 GHz used by the first network 292 (e.g., a legacy network). During reception, an RF signal may be obtained from the first network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242) and preprocessed by an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal into a baseband signal so that it can be processed by the first communication processor 212.

[0050] During transmission, the second RFIC 224 can convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal (hereinafter, a 5G Sub6 RF signal) in the Sub6 band (e.g., approximately 6 GHz or less) used by the second network 294 (e.g., a 5G network). During reception, the 5G Sub6 RF signal may be obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244) and preprocessed by an RFFE (e.g., the second RFFE 234). The second RFIC 224 can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by a corresponding communication processor of the first communication processor 212 or the second communication processor 214.

[0051] The third RFIC 226 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, a 5G Above 6 RF signal) in the 5G Above 6 band (e.g., approximately 6 GHz to approximately 60 GHz) used in the second network 294 (e.g., a 5G network). Upon reception, the 5G Above 6 RF signal may be obtained from the second network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and preprocessed by the third RFFE 236. The third RFIC 226 may convert the preprocessed 5G Above 6 RF signal into a baseband signal so that it can be processed by the second communication processor 214. According to one embodiment, the third RFFE 236 may be formed as part of the third RFIC 226.

[0052] According to one embodiment, the electronic device 101 may include a fourth RFIC 228, either separately from or at least as part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 to an RF signal in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) (hereinafter, an IF signal) and then transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal to a 5G Above 6 RF signal. Upon reception, the 5G Above 6 RF signal may be received from the second network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and converted to an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal to a baseband signal for processing by the second communication processor 214.

[0053] According to one embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single chip or a single package. According to one embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least part of a single chip or a single package. According to one embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted and may be combined with another antenna module to process RF signals of corresponding multiple bands.

[0054] According to one embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate to form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 may be disposed on a portion (e.g., a bottom surface) of a second substrate (e.g., a sub-PCB) separate from the first substrate, and the antenna 248 may be disposed on another portion (e.g., an upper surface) of the second substrate (e.g., a sub-PCB), thereby forming the third antenna module 246. By disposing the third RFIC 226 and the antenna 248 on the same substrate, the length of the transmission line between them can be reduced. This can reduce, for example, loss (e.g., attenuation) of signals in a high-frequency band (e.g., approximately 6 GHz to approximately 60 GHz) used in 5G network communication due to the transmission line. This can improve the quality or speed of communication between the electronic device 101 and the second network 294 (e.g., a 5G network).

[0055] According to one embodiment, antenna 248 may be configured as an antenna array including multiple antenna elements usable for beamforming. In this case, third RFIC 226 may include, for example, multiple phase shifters 238 corresponding to the multiple antenna elements as part of third RFFE 236. During transmission, each of the multiple phase shifters 238 may shift the phase of a 5G Above 6 RF signal transmitted to an external device (e.g., a base station of a 5G network) from electronic device 101 via the corresponding antenna element. During reception, each of the multiple phase shifters 238 may shift the phase of a 5G Above 6 RF signal received from the external device via the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception using beamforming between electronic device 101 and the external device.

[0056] The second network 294 (e.g., a 5G network) may be operated independently (e.g., Stand-Alone (SA)) or connected (e.g., Non-Stand Alone (NSA)) to the first network 292 (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)) and may not have a core network (e.g., a next generation core (NGC)). In this case, after accessing the access network of the 5G network, the electronic device 101 can access an external network (e.g., the Internet) under the control of the core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., NR (New Radio) protocol information) may be stored in memory 230 and accessed by other components (e.g., processor 120, first communication processor 212, or second communication processor 214).

[0057] FIG. 3 is a diagram illustrating a protocol stack structure of a network 100 for legacy communication and / or 5G communication according to one embodiment.

[0058] Referring to FIG. 3 , the network 100 in the illustrated embodiment may include an electronic device 101, a legacy network 392, a 5G network 394, and a server 108.

[0059] The electronic device 101 may include an Internet Protocol 312, a first communication protocol stack 314, and a second communication protocol stack 316. The electronic device 101 may communicate with the server 108 over a legacy network 392 and / or a 5G network 394.

[0060] According to one embodiment, electronic device 101 may use Internet protocols 312 (e.g., TCP, UDP, IP) to perform Internet communications with server 108. Internet protocols 312 may be executed, for example, by a main processor included in electronic device 101 (e.g., main processor 121 of FIG. 1).

[0061] According to another embodiment, electronic device 101 can wirelessly communicate with legacy network 392 using first communication protocol stack 314. According to yet another embodiment, electronic device 101 can wirelessly communicate with 5G network 394 using second communication protocol stack 316. First communication protocol stack 314 and second communication protocol stack 316 can be executed by, for example, one or more communication processors included in electronic device 101 (e.g., wireless communication module 192 of FIG. 1 ).

[0062] The server 108 may include an internet protocol 322. The server 108 may transmit and receive data related to the internet protocol 322 to and from the electronic device 101 over the legacy network 392 and / or the 5G network 394. According to one embodiment, the server 108 may include a cloud computing server that resides outside the legacy network 392 or the 5G network 394. In other embodiments, the server 108 may include an edge computing server (or a mobile edge computing (MEC) server) located within at least one of the legacy network and the 5G network 394.

[0063] The legacy network 392 may include an LTE base station 340 and an EPC 342. The LTE base station 340 may include an LTE communication protocol stack 344. The EPC 342 may include a legacy NAS protocol 346. The legacy network 392 can perform LTE wireless communication with the electronic device 101 using the LTE communication protocol stack 344 and the legacy NAS protocol 346.

[0064] The 5G network 394 may include an NR base station 350 and a 5G cellular phone 352. The NR base station 350 may include an NR communication protocol stack 354. The 5G cellular phone 352 may include a 5G NAS protocol 356. The 5G network 394 can perform NR wireless communication with the electronic device 101 using the NR communication protocol stack 354 and the 5G NAS protocol 356.

[0065] According to one embodiment, the first communication protocol stack 314, the second communication protocol stack 316, the LTE communication protocol stack 344, and the NR communication protocol stack 354 may include a control plane protocol for transmitting and receiving control messages and a user plane protocol for transmitting and receiving user data. The control messages may include, for example, messages related to at least one of security control, bearer setup, authentication, registration, or mobility management. The user data may include, for example, the remaining data excluding the control messages.

[0066] According to one embodiment, the control plane protocol and the user plane protocol may include a physical (PHY), medium access control (MAC), radio link control (RLC), or packet data convergence protocol (PDCP) layer. The PHY layer may, for example, channel code and modulate data received from a higher layer (e.g., a MAC layer) and transmit the data over a wireless channel, and may demodulate and decode the data received over the wireless channel and transmit the data to a higher layer. The PHY layers included in the second communication protocol stack 316 and the NR communication protocol stack 354 may further perform operations related to beamforming. The MAC layer may, for example, logically / physically map data to wireless channels for transmitting and receiving data and perform hybrid automatic repeat request (HARQ) for error correction. The RLC layer may, for example, concatenate, segment, or reassemble data, and perform data order check, reordering, or duplication check. The PDCP layer may perform operations related to, for example, ciphering and data integrity of control messages and user data. The second communication protocol stack 316 and the NR communication protocol stack 354 may further include a service data adaptation protocol (SDAP). The SDAP may manage, for example, radio bearer allocation based on the quality of service (QoS) of user data.

[0067] According to various embodiments, the control plane protocols may include a radio resource control (RRC) layer and a non-access stratum (NAS) layer. The RRC layer may process control data related to, for example, radio bearer setup, paging, or mobility management. The NAS may process control messages related to, for example, authentication, registration, and mobility management.

[0068] FIG. 4A illustrates a wireless communication system providing a legacy and / or 5G communication network according to various embodiments. FIG. 4B illustrates a wireless communication system providing a legacy and / or 5G communication network according to various embodiments. FIG. 4C illustrates a wireless communication system providing a legacy and / or 5G communication network according to various embodiments. Referring to FIGS. 4A, 4B, and 4C, network environments 100A, 100B, and 100C may include at least one of a legacy network and a 5G network. The legacy network may include, for example, a 3GPP-standard 4G or LTE base station 450 (e.g., an eNodeB (eNB)) supporting wireless connection with electronic device 101 and an evolved packet core (EPC) 451 managing 4G communication. The 5G network may include, for example, an NR (New Radio) base station 450 (e.g., a gNB (gNodeB)) that supports wireless connection with the electronic device 101 and a 5GC 452 (5th generation core) that manages the 5G communication of the electronic device 101.

[0069] According to various embodiments, the electronic device 101 may transmit and receive control messages and user data via legacy communication and / or 5G communication. The control messages may include, for example, messages related to at least one of security control, bearer setup, authentication, registration, or mobility management of the electronic device 101. The user data may refer to, for example, user data other than control messages transmitted and received between the electronic device 101 and the core network 430 (e.g., EPC 442).

[0070] Referring to FIG. 4A, an electronic device 101 according to one embodiment can transmit and receive at least one of a control message or user data to and from at least a portion of a 5G network (e.g., an NR base station 450, a 5G base station 452) using at least a portion of a legacy network (e.g., an LTE base station 440, an EPC 442).

[0071] According to various embodiments, the network environment 100A may include a network environment that provides wireless communication dual connectivity (multi-RAT (radio access technology) dual connectivity, MR-DC) to an LTE base station 440 and an NR base station 450, and transmits and receives control messages to and from the electronic device 101 through one of a core network 430 of an EPC 442 or a 5GC 452.

[0072] According to various embodiments, in an MR-DC environment, one of the LTE base station 440 or the NR base station 450 can operate as a master node (MN) 410, and the other base station can operate as a secondary node (SN) 420. The MN 410 is connected to a core network 430 and can transmit and receive control messages. The MN 410 and the SN 420 are connected via a network interface and can transmit and receive messages related to radio resource (e.g., communication channel) management to and from each other.

[0073] According to various embodiments, the MN 410 may be configured with an LTE base station 450, the SN 420 may be configured with an NR base station 450, and the core network 430 may be configured with an EPC 442. For example, control messages may be transmitted and received via the LTE base station 440 and the EPC 442, and user data may be transmitted and received via the LTE base station 450 and the NR base station 450.

[0074] Referring to FIG. 4B, according to various embodiments, the 5G network can independently transmit and receive control messages and user data to and from the electronic device 101.

[0075] 4C , various embodiments of the legacy network and the 5G network can provide independent data transmission and reception. For example, the electronic device 101 and the EPC 442 can transmit and receive control messages and user data via an LTE base station 450. As an example, the electronic device 101 and the 5G 452 can transmit and receive control messages and user data via an NR base station 450.

[0076] According to various embodiments, the electronic device 101 may be registered with at least one of the EPC 442 and the 5GC 452 to send and receive control messages.

[0077] According to various embodiments, the EPC 442 or the 5GC 452 may interwork to manage communications of the electronic device 101. For example, movement information of the electronic device 101 may be transmitted and received via an interface between the EPC 442 and the 5GC 452.

[0078] FIG. 5 illustrates an electronic device and a cellular network according to one embodiment.

[0079] An electronic device (eg, electronic device 101 of FIG. 1) can transmit and / or receive data over terrestrial and / or non-terrestrial networks.

[0080] A terrestrial network can refer to a network that can provide data communication via a first node (e.g., NR base station 450 in FIG. 4B or LTE base station 440 in FIG. 4C) 510 that is fixed to the ground.

[0081] A non-terrestrial network may refer to a network that can provide data communication using satellites 520 that are not fixed to the earth.

[0082] The first node 510 may be a base station supporting the first cellular communication or the second cellular communication. The first cellular communication may be any one of various cellular communication methods that can be supported by an electronic device (e.g., the electronic device 101 in FIG. 1 ), and may refer to, for example, a communication method on the second cellular network 294 in FIG. 2 . For example, the first cellular communication may be a communication method using a fifth generation mobile communication method (e.g., new radio (NR)). The second cellular communication may be any one of various cellular communication methods that can be supported by the electronic device 101, and may refer to, for example, a communication method on the first cellular network 292 in FIG. 2 . For example, the second cellular communication may be a communication method using a fourth generation mobile communication method (e.g., long term evolution (LTE)).

[0083] The first node 510 can transmit or receive signals in a frequency band supported by the first cellular communication or the second cellular communication. When the electronic device 101 is connected to a terrestrial network via the first node 510, data communication can be performed using signals in the frequency band supported by the first node 510.

[0084] The satellite 520 may function as a base station supporting the first cellular communication or the second cellular communication. The satellite 520 may transmit or receive signals in a frequency band supported by the first cellular communication or the second cellular communication. When the electronic device 101 is connected to a non-terrestrial network via the satellite 520, data communication may be performed using signals in the frequency band supported by the satellite 520.

[0085] The electronic device 101 is connected to a non-terrestrial network via a satellite 520 and can provide various services.

[0086] The distance between the electronic device 101 and the satellite 520 may be greater than the distance between the electronic device 101 and the first node 510. When the distance between the electronic device 101 and the satellite 520 is greater, path loss in the data transmission or reception path between the electronic device 101 and the satellite may be greater, increasing the time it takes for the electronic device 101 to transmit or receive data. Furthermore, the transmission data rate of the electronic device 101 may be low due to limitations on the strength of the signal output by the electronic device 101. Therefore, communication services using the satellite 520 may be used within a limited range. According to one example, a non-terrestrial network providing communication services using the satellite 520 may only provide certain services (e.g., short messaging service (SMS) and multimedia messaging service (MMS)) and may not be able to provide other services (e.g., transmission and / or reception of user data).

[0087] The electronic device 101 may transmit a signal requesting a specific service (e.g., transmission of user data) (e.g., requesting establishment of a packet data unit (PDU) session for transmitting user data) to the network via the satellite 520. If the network cannot provide the specific service, it may transmit a reject message to the electronic device 101 via the satellite 520 in response to the request signal. Due to the relatively long distance between the electronic device 101 and the satellite 520, it may take the electronic device 101 a relatively long time to receive the reject message, which may result in unnecessary power consumption and / or delay time until the reject message is received.

[0088] The following describes an embodiment in which the electronic device 101 prevents (or refrains from) transmitting unnecessary signals and / or data to a non-terrestrial network, thereby preventing (or reducing) unnecessary resource consumption.

[0089] FIG. 6 is a block diagram of an electronic device according to one embodiment.

[0090] Referring to FIG. 6, an electronic device (e.g., electronic device 101 of FIG. 1) according to various embodiments of the present invention may include a communication circuit (e.g., wireless communication module 192 of FIG. 1) 610, a communication processor (e.g., processor 120 of FIG. 1, first communication processor 212, and / or second communication processor 214 of FIG. 2) 620, and / or memory (e.g., memory 130 of FIG. 1) 630.

[0091] The communication circuit 610 is a communication circuit supporting first cellular communication and / or second cellular communication, and can provide the electronic device 101 with communication with an external electronic device (e.g., the electronic device 104 in FIG. 1 ) using the first cellular communication and / or the second cellular communication. The first cellular communication can be any one of various cellular communication methods that can be supported by the electronic device (e.g., the electronic device 101 in FIG. 1 ), and can refer to, for example, a communication method on the second cellular network 294 in FIG. 2 . For example, the first cellular communication can be a communication method using a fifth generation mobile communication method (e.g., new radio (NR)). The second cellular communication can be any one of various cellular communication methods that can be supported by the electronic device 101, and can refer to, for example, a communication method on the first cellular network 292 in FIG. 2 . For example, the second cellular communication can be a communication method using a fourth generation mobile communication method (e.g., long term evolution (LTE)).

[0092] The communication processor 620 may be operatively coupled to the communication circuitry 610. The communication processor 620 may control the configuration of the electronic device 101. For example, the communication processor 620 may control the configuration of the electronic device 101 in response to one or more instructions stored in a memory (e.g., memory 130 of FIG. 1).

[0093] The communications processor 620 may control the communications circuitry 610 to transmit and / or receive data over terrestrial and / or non-terrestrial networks.

[0094] A terrestrial network may refer to a network that can provide data communication via a first node (eg, first node 510 in FIG. 5) that is fixed on the ground.

[0095] A non-terrestrial network may refer to a network that can provide data communication via nodes that are not fixed to the earth (eg, satellites 520 in FIG. 5).

[0096] The communication processor 620 can control the communication circuit 610 to search for a network in order to connect to the network, and if the network search is successful, the communication processor 620 can perform a series of procedures to connect to the searched network.

[0097] While searching for a network, the communications processor 620 may receive system information transmitted or broadcast by nodes (e.g., satellites 520 in FIG. 5) included in the network (e.g., a non-terrestrial network).

[0098] The communications processor 620 can determine whether the searched network is a non-terrestrial network based on the received system information.

[0099] The system information broadcast by node 520 may include various information. According to one example, the system information may include SIB 1 defined in 3GPP TS.36.331 v15.6. SIB 1 may include identification information of the network in which node 520 is included (e.g., mobile country code (MCC), public land mobile network (PLMN)), information required when connecting (or random access (RA)) to node 520, and / or information indicating that the network is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

[0100] The communication processor 620 can determine that the searched network is a non-terrestrial network if it determines that the network identification information included in the system information transmitted or broadcast by the node 520 is the specified identification information (e.g., the identification information of a non-terrestrial network). According to one example, the MCC of the non-terrestrial network may start with 9. ...

[0101] The communication processor 620 can determine that the searched network is a non-terrestrial network based on information indicating that the network is a non-terrestrial network included in the system information transmitted or broadcast by the node 520. According to one example, the communication processor 620 can determine that the searched network is a non-terrestrial network based on determining that the cellBarredNTN information element (IE) is indicated as not barred. The communication processor 620 can determine that the searched network is a terrestrial network based on determining that the cellBarredNTN information element (IE) is indicated as barred or based on the cellBarredNTN IE not being included in the system information.

[0102] According to one example, the system information may include SIB 19 defined in 3GPP TS.38.304. SIB 19 may include system information that is transmitted or broadcast when the network in which node 520 is included is a non-terrestrial network, and may include information related to the non-terrestrial network (e.g., altitude information of node 520, movement speed information of node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. When the system information transmitted or broadcast by node 520 is SIB 19, the communication processor 620 can confirm that the searched network is a non-terrestrial network.

[0103] The communications processor 620 can determine that the searched network is a non-terrestrial network and, based on mapping data stored in memory 630, determine the services that the searched network supports (or does not support).

[0104] The mapping data may be data in which identification information of a non-terrestrial network and information on services supported by the non-terrestrial network are mapped and stored. According to one example, the mapping data may be implemented as shown in Table 1 below and stored in the memory 630.

[0105] [Table 1]

[0106] Referring to Table 1, the mapping data may be data that maps whether a service is supported in a specific network. For example, the communication processor 620 may determine, based on the mapping data, that the first network (991-01) supports the SMS service but does not support the MMS service, the user data transmission and / or reception service, and the satellite-only PDU service. As an example, the communication processor 620 may determine, based on the mapping data, that the second network (992-02) supports the SMS service and the MMS service but does not support the user data transmission and / or reception service and the satellite-only PDU service. As an example, the communication processor 620 may determine, based on the mapping data, that the third network (993-03) supports the SMS service, the MMS service, and the user data transmission and / or reception service but does not support the satellite-only PDU service. As an example, the communication processor 620 may determine, based on the mapping data, that the fourth network (994-04) supports the SMS service, the MMS service, and the satellite-only PDU service but does not support the user data transmission and / or reception service. A satellite-only PDU service is a service for transmitting and / or receiving user data using a PDU that can only be used on a non-terrestrial network, and can refer to a service for transmitting and / or receiving user data using a PDU that cannot be connected via a terrestrial network.

[0107] The communication processor 620 may not transmit a PDU session establishment request message to the network for a service that the network does not support. The communication processor 620 can prohibit the operation of transmitting a PDU session establishment request message to the network for a service that the network does not support. By not transmitting a PDU session establishment request message to the network for a service that the network does not support, the communication processor 620 can prevent and / or reduce unnecessary resource consumption due to the transmission of a PDU session establishment request message.

[0108] According to one example, the communication processor 620 may be coupled to a network via a first cellular communication that may support SMS transmission or reception using a non-access stratum (NAS), and thus may require the establishment of a separate PDU session for the SMS service.

[0109] The communication processor 620 may determine, based on the mapping data, that the network connected via the first cellular communication supports only SMS services (e.g., the first network), and may not transmit a signal requesting the establishment of another PDU session to the node 520. Thus, the electronic device 101 may reduce unnecessary resource consumption or delay time due to the receipt of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to a network that does not support data transmission and / or reception using a PDU session.

[0110] According to one example, the communication processor 620 may be coupled to the network via a second cellular communication, which may require the establishment of a PDU session for SMS transmission or reception.

[0111] The communication processor 620 can determine, based on the mapping data, that the network connected via the second cellular communication supports only the SMS service (e.g., the first network), and can transmit a signal to the node 520 requesting the establishment of a PDU session for the SMS service. However, the communication processor 620 may not transmit a signal to the node 520 requesting the establishment of another PDU session for a service other than the SMS service. Therefore, the electronic device 101 can reduce unnecessary resource consumption or delay time due to the reception of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to a network that does not support data transmission and / or reception using a PDU session.

[0112] The communication processor 620 can determine, based on the mapping data, that the network connected by the first cellular communication or the second cellular communication supports the SMS service and the MMS service but does not support the transmission or reception of user data (e.g., the second network), and can transmit a signal to the node 520 requesting the establishment of a PDU session for the MMS service. However, the communication processor 620 may not transmit a signal to the node 520 requesting the establishment of a separate PDU session for a service other than the MMS service (e.g., a user data transmission or reception service). Thus, the electronic device 101 can reduce unnecessary resource consumption or delay time due to the reception of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to a network that does not support the transmission and / or reception of user data via a PDU session.

[0113] The communication processor 620 can determine, based on the mapping data, that the network connected by the first cellular communication or the second cellular communication supports the SMS service, the MMS service, and the transmission or reception of user data (e.g., a third network), and can transmit a signal requesting establishment of a PDU session for the MMS service and / or a signal requesting establishment of a PDU session for a user data transmission or reception service to the node 520. After transmitting a signal requesting establishment of a PDU session for a user data transmission or reception service, the communication processor 620 can perform a series of procedures for establishing a PDU session for the user data transmission or reception service. The communication processor 620 can transmit data to the network or receive data from the network via the PDU session for the user data transmission or reception service.

[0114] However, the communication processor 620 may receive a signal from an application processor (e.g., processor 120 in FIG. 1) requesting prohibition of transmission and / or reception of user data by applications other than designated applications. The application processor 120 may pre-designate applications that can transmit or receive data via a non-terrestrial network, and may restrict applications other than the designated applications from transmitting or receiving user data. According to one example, the application processor 120 may not transmit user data generated by applications other than the designated applications to the communication processor 620. Alternatively, the application processor 120 may control the communication processor 620 to transmit user data generated by applications other than the designated applications to the communication processor 620, but not transmit the user data through a PDU session for a user data transmission or reception service.

[0115] The communication processor 620 can determine, based on the mapping data, that the network connected via the first cellular communication or the second cellular communication supports SMS service, MMS service, and transmission or reception of user data via satellite-dedicated PDU (e.g., a fourth network), and can transmit a signal requesting establishment of a satellite-dedicated PDU session to the node 520. The communication processor 620 can prohibit transmission of a signal requesting establishment of a PDU session for transmission or reception of user data. After transmitting a signal requesting establishment of a satellite-dedicated PDU session, the communication processor 620 can perform a series of procedures for establishing a satellite-dedicated PDU session. The communication processor 620 can transmit data to the network or receive data from the network via the satellite-dedicated PDU session.

[0116] However, the communication processor 620 may receive a signal from an application processor (e.g., processor 120 in FIG. 1) requesting prohibition of transmission and / or reception of user data by applications other than designated applications. The application processor 120 may pre-designate applications that can transmit or receive data via the non-terrestrial network, and may restrict applications other than the designated applications from transmitting or receiving user data. According to one example, the application processor 120 may not transmit user data generated by applications other than the designated applications to the communication processor 620. Alternatively, the application processor 120 may control the communication processor 620 so that, even if user data generated by applications other than the designated applications is transmitted to the communication processor 620, the user data is not transmitted via a satellite-only PDU session.

[0117] As described above, the electronic device 101 can reduce unnecessary resource consumption or delay time due to receiving a reject message that occurs when transmitting a signal requesting the establishment of a PDU session for a service that is not supported by the non-terrestrial network by not transmitting a message to the node 520 requesting the establishment of a PDU session for a service that is not supported by the non-terrestrial network.

[0118] In addition to prohibiting the establishment of a PDU session, the electronic device 101 can reduce the size of the data contained in the signal transmitted to the non-terrestrial network, thereby reducing the delay time caused by the large distance between the node 520 and the electronic device 101.

[0119] The communications processor 620 may receive a UE capability request message from the network during a registration procedure with the network or after registration with the network.

[0120] After an RRC connection with the electronic device 101 is established, the network may send a UE capability request message to the electronic device 101 when UE capability information is required. The UE capability information may refer to information indicating the capabilities of the electronic device 101 related to cellular communication of the electronic device 101. For example, the UE capability information may include information indicating frequency bands that the electronic device 101 can support or information indicating a combination of frequency bands that the electronic device 101 can support. The combination of frequency bands that the electronic device 101 can support may refer to a combination of frequency bands on which the electronic device 101 can simultaneously transmit or receive data. For example, if the electronic device 101 can simultaneously transmit (or receive) a signal via a first frequency band and a signal via a second frequency band, the combination of frequency bands that the electronic device 101 can support may be the first frequency band and the second frequency band.

[0121] The communications processor 620 can transmit UE capability information to the network via the node 520 by receiving a UE capability request message from the network.

[0122] When transmitting the UE capability information, the communications processor 620 may transmit the UE capability information excluding (or not including) information not related to the network to the network.

[0123] According to one example, if the network is a non-terrestrial network, the network may not support a communication scheme (e.g., carrier aggregation (CA), E-UTRA-NR dual connectivity (EN-DC), or multi-RAT dual connectivity (MR-DC)) that supports transmission or reception of data via multiple frequency bands. If the network does not support transmission or reception of data via multiple frequency bands, the combinations of frequency bands that the electronic device 101 can support may be unnecessary information for the network. Therefore, the communication processor 620 can reduce the time (or delay time) required to transmit the UE capability information to the network by transmitting UE capability information that does not include information indicating the combinations of frequency bands supported by the electronic device 101.

[0124] According to one example, if the network is a non-terrestrial network, the network may not support a communication scheme (e.g., carrier aggregation (CA), E-UTRA-NR Dual connectivity (EN-DC), or Multi-RAT dual connectivity (MR-DC)) that supports transmission or reception of data via multiple frequency bands. If the network does not support transmission or reception of data via multiple frequency bands, information indicating whether the electronic device 101 supports different generations of cellular communication schemes may be unnecessary for the network. Therefore, the communication processor 620 can reduce the time (or delay) required to transmit the UE capability information to the network by transmitting UE capability information that does not include information indicating whether the electronic device 101 supports different generations of cellular communication schemes.

[0125] According to one example, if the network is a non-terrestrial network, the network may not support a communication method (e.g., MIMO (multi-input, multi-output)) that supports data transmission or reception using multiple antennas. If the network does not support data transmission or reception via multiple frequency bands, information indicating whether the electronic device 101 supports a communication method that supports data transmission or reception using multiple antennas may be unnecessary information for the network. Therefore, the communication processor 620 can reduce the time (or delay time) required to transmit the UE capability information to the network by transmitting UE capability information that does not include information indicating whether the electronic device 101 supports a communication method that supports data transmission or reception using multiple antennas.

[0126] In addition to the examples above, the communications processor 620 can reduce the time (or delay) required to transmit UE capability information to the network by transmitting UE capability information excluding information not relevant to the network.

[0127] According to one example, if the network is a non-terrestrial network, the network may not support various settings (e.g., conditional handover) of a specific frequency band (e.g., a specific frequency band that supports time duplex divisional (TDD) (e.g., FR2-1 (24250 MHz to 52600 MHz), FR2-2 (52600 MHz to 71000 MHz))). If the network does not support various settings of a specific frequency band, information indicating whether the electronic device 101 supports various settings of a specific frequency band may be unnecessary information for the network. Therefore, the communication processor 620 can reduce the time (or delay time) required to transmit the UE capability information to the network by transmitting UE capability information that does not include information indicating whether the electronic device 101 supports various settings of a specific frequency band.

[0128] The communications processor 620 can reduce the time (or delay) it takes to transmit UE capability information to the network by transmitting UE capability information that excludes information that is not related to the network but includes information that is related to the network.

[0129] According to one example, if the network is a non-terrestrial network, the network may support a specific frequency band (e.g., FR1 (410 MHz to 7125 MHz) band supporting FDD (frequency divisional duplex)). If the network supports various settings of the specific frequency band, information indicating whether the electronic device 101 supports various settings of the specific frequency band may be information required by the network. Therefore, the communication processor 620 can reduce the time (or delay time) required to transmit the UE capability information by transmitting, to the network, UE capability information including information indicating whether the electronic device 101 supports various settings of the specific frequency band.

[0130] According to one example, the communication processor 620 can also transmit UE capability information to the network, including information expected to be required by the network. According to one example, if the electronic device 101 supports parallel measurement for measuring the quality of signals in multiple frequency bands, the communication processor 620 can transmit UE capability information to the network, including information related to the parallel measurement.

[0131] The communications processor 620 can determine whether to provide a specified service based on system information broadcast by the connected network (or node 520).

[0132] According to one example, the system information may include SIB 19 defined in 3GPP TS.38.304. SIB 19 may include system information that is transmitted or broadcast when the network in which node 520 is included is a non-terrestrial network, and may include information related to the non-terrestrial network (e.g., altitude information of node 520, movement speed information of node 520). For example, the node that transmits or broadcasts SIB 19 may be a node included in the non-terrestrial network.

[0133] The communication processor 620 can check the altitude information of the node 520 included in the system information transmitted or broadcast by the node 520, and determine whether to provide the specified service based on whether the altitude of the node 520 is greater than or equal to a specified value (e.g., a threshold value).

[0134] The altitude information of node 520 may include a value included in the semiMajorAxis field of the EphemerisInfo IE of the NTN-config included in SIB 19. The communication processor 620 can determine the altitude of node 520 using the value included in the field and a method defined in TS 38.331 (e.g., Equation 1).

[0135]

number

[0136] The specified service may be a service that requires low latency. For example, the specified service may include a voice call or a video call. When the electronic device 101 performs a service that requires low latency, the greater the distance between the electronic device 101 and the node 520, the lower the quality of the service may be, or the service may be impossible to perform. Therefore, the communication processor 620 may not perform the specified service or may suspend the execution of the specified service if the altitude of the node 520 is equal to or greater than (or exceeds) a specified value (threshold). The specified value may be a value associated with the specified service and may be a value associated with the maximum altitude of the node 520 at which the specified service can be performed. The specified value may be a value pre-stored in the memory 630 or a value associated with the altitude of the node 520.

[0137] The communications processor 620 can perform a specified service or maintain the execution of a specified service when the altitude of the node 520 is at or below a specified value (threshold).

[0138] The communication processor 620 may encode data associated with a designated service using a codec that supports the lowest data rate while performing the designated service. The communication processor 620 may reduce the size of the data using a codec that supports the lowest data rate, thereby reducing the time (or delay) required to transmit the encoded data.

[0139] FIG. 7 is a diagram illustrating an embodiment in which an electronic device in accordance with an embodiment prohibits a request signal for establishing a PDU session.

[0140] An electronic device (eg, electronic device 101 of FIG. 6) may transmit a registration request signal to network 701 in operation 711 .

[0141] The electronic device 101 can control the communication circuit 610 to search the network 701 for connection to the network 701. If the electronic device 101 is successful in searching for the network 701, the electronic device 101 can perform a series of procedures to connect to the searched network 701.

[0142] While searching the network 701, the electronic device 101 may receive system information transmitted or broadcast by a node (e.g., satellite 520 in FIG. 5) included in the network 701 (e.g., a non-terrestrial network).

[0143] The electronic device 101 can determine whether the searched network 701 is a non-terrestrial network based on the received system information.

[0144] The system information broadcast by node 520 may include various information. According to one example, the system information may include SIB 1 defined in 3GPP TS.36.331 v15.6. SIB 1 may include identification information of the network 701 in which node 520 is included (e.g., mobile country code (MCC), public land mobile network (PLMN)), information required when connecting (or random access (RA)) to node 520, and / or information indicating that network 701 is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

[0145] The electronic device 101 can confirm that the searched network 701 is a non-terrestrial network if it confirms that the identification information of the network 701 included in the system information transmitted or broadcast by the node 520 is the specified identification information (e.g., the identification information of a non-terrestrial network).

[0146] The electronic device 101 can determine that the searched network 701 is a non-terrestrial network based on information indicating that the network 701 is a non-terrestrial network, which is included in the system information transmitted or broadcast by the node 520. According to one example, the electronic device 101 can determine that the searched network 701 is a non-terrestrial network based on determining that the cellBarredNTN IE (information element) is indicated as not barred. The electronic device 101 can determine that the searched network 701 is a terrestrial network 701 based on determining that the cellBarredNTN IE (information element) is indicated as barred or based on the cellBarredNTN IE not being included in the system information.

[0147] According to one example, the system information may include SIB 19 defined in 3GPP TS.38.304. SIB 19 may include system information that is transmitted or broadcast when the network 701 to which the node 520 belongs is a non-terrestrial network, and may include information related to the non-terrestrial network (e.g., altitude information of the node 520, movement speed information of the node 520). For example, the node that transmits or broadcasts SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the electronic device 101 can confirm that the searched network 701 is a non-terrestrial network.

[0148] The electronic device 101 can determine that the searched network 701 is a non-terrestrial network and, based on the mapping data stored in the memory 630, determine the services that the searched network 701 supports (or does not support).

[0149] The mapping data may be data in which identification information of non-terrestrial networks and information on services supported by the non-terrestrial networks are mapped and stored.

[0150] The electronic device 101 and the network 701 may perform a registration procedure for the electronic device 101 in operation 713 .

[0151] The electronic device 101 can complete registration with the network 701 through a series of operations including initial access to a node 520 included in the searched network 701 and an authentication procedure for the electronic device 101. Once registration with the network 701 is complete, the electronic device 101 can use the services provided by the network 701.

[0152] In operation 715, the electronic device 101 may prohibit the transmission of a request signal for establishing a PDU session.

[0153] The electronic device 101 may not transmit a PDU session establishment request message to the network 701 for a service that is not supported by the network 701. The electronic device 101 may prohibit (or refrain from) transmitting a PDU session establishment request message to the network 701 for a service that is not supported by the network 701. By not transmitting a PDU session establishment request message to the network 701 for a service that is not supported by the network 701, the electronic device 101 can prevent unnecessary resource consumption due to the transmission of a PDU session establishment request message.

[0154] According to one example, the electronic device 101 may be coupled to the network 701 via a first cellular communication. The first cellular communication may support SMS transmission or reception via a non-access stratum (NAS), and therefore the first cellular communication may not require the establishment of a separate PDU session for the SMS service.

[0155] Based on the mapping data, the electronic device 101 may determine that the network 701 connected via the first cellular communication supports only SMS services (e.g., the first network 701), and may not need to send a signal requesting the establishment of a separate PDU session to the node 520. Thus, the electronic device 101 may reduce unnecessary resource consumption or delay time due to the receipt of a reject message that occurs when sending a signal requesting the establishment of a PDU session to a network 701 that does not support data transmission and / or reception via a PDU session.

[0156] FIG. 8 illustrates an embodiment in which an electronic device according to an embodiment prohibits a request signal for establishing a PDU session for a service that is not supported by the network.

[0157] An electronic device (eg, electronic device 101 of FIG. 6) may transmit a registration request signal to network 701 in operation 811 .

[0158] The electronic device 101 can control the communication circuit 610 to search the network 701 for connection to the network 701. If the electronic device 101 is successful in searching for the network 701, the electronic device 101 can perform a series of procedures to connect to the searched network 701.

[0159] While searching the network 701, the electronic device 101 may receive system information transmitted or broadcast by a node (e.g., satellite 520 in FIG. 5) included in the network 701 (e.g., a non-terrestrial network).

[0160] The electronic device 101 can determine whether the searched network 701 is a non-terrestrial network based on the received system information.

[0161] The system information broadcast by node 520 may include various information. According to one example, the system information may include SIB 1 defined in 3GPP TS.36.331 v15.6. SIB 1 may include identification information of the network 701 in which node 520 is included (e.g., mobile country code (MCC), public land mobile network (PLMN)), information required when connecting (or random access (RA)) to node 520, and / or information indicating that network 701 is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

[0162] If the electronic device 101 confirms that the identification information of the network 701 included in the system information transmitted or broadcast by the node 520 is the specified identification information (e.g., the identification information of a non-terrestrial network), it can confirm that the searched network 701 is a non-terrestrial network.

[0163] The electronic device 101 can determine that the searched network 701 is a non-terrestrial network based on information indicating that the network 701 is a non-terrestrial network, which is included in the system information transmitted or broadcast by the node 520. According to one example, the electronic device 101 can determine that the searched network 701 is a non-terrestrial network based on determining that the cellBarredNTN IE (information element) is indicated as not barred. The electronic device 101 can determine that the searched network 701 is a terrestrial network 701 based on determining that the cellBarredNTN IE (information element) is indicated as barred or based on the cellBarredNTN IE not being included in the system information.

[0164] According to one example, the system information may include SIB 19 defined in 3GPP TS.38.304. SIB 19 may include system information that is transmitted or broadcast when the network 701 to which the node 520 belongs is a non-terrestrial network, and may include information related to the non-terrestrial network (e.g., altitude information of the node 520, movement speed information of the node 520). For example, the node that transmits or broadcasts SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by the node 520 is SIB 19, the electronic device 101 can confirm that the searched network 701 is a non-terrestrial network.

[0165] The electronic device 101 can determine that the searched network 701 is a non-terrestrial network and, based on the mapping data stored in the memory 630, determine the services that the searched network 701 supports (or does not support).

[0166] The mapping data may be data in which identification information of non-terrestrial networks and information on services supported by the non-terrestrial networks are mapped and stored.

[0167] The electronic device 101 and the network 701 may perform a registration procedure for the electronic device 101 in operation 813 .

[0168] The electronic device 101 can complete registration with the network 701 through a series of operations including initial access to a node 520 included in the searched network 701 and an authentication procedure for the electronic device 101. Once registration with the network 701 is complete, the electronic device 101 can use the services provided by the network 701.

[0169] In operation 815, the electronic device 101 may send a PDU session establishment request message to the network 701 for performing a network-supported service.

[0170] Based on the mapping data, the electronic device 101 can determine that the network 701 connected via the first cellular communication or the second cellular communication supports the SMS service, the MMS service, and the transmission or reception of user data (e.g., the third network 701), and can transmit a signal requesting the establishment of a PDU session for the MMS service and / or a signal requesting the establishment of a PDU session for a user data transmission or reception service to the node 520. After transmitting the signal requesting the establishment of a PDU session for a user data transmission or reception service, the electronic device 101 can perform a series of procedures for establishing a PDU session for a user data transmission or reception service. The electronic device 101 can transmit data to the network 701 or receive data from the network 701 via the PDU session for the user data transmission or reception service.

[0171] However, the electronic device 101 may receive a signal from an application processor (e.g., processor 120 in FIG. 1) requesting prohibition of transmission and / or reception of user data by applications other than designated applications. The application processor 120 may pre-designate applications that can transmit or receive data via a non-terrestrial network, and may restrict applications other than the designated applications from transmitting or receiving user data. According to one example, the application processor 120 may not transmit user data generated by applications other than the designated applications to the electronic device 101. The application processor 120 may control the electronic device 101 so that, even if user data generated by applications other than the designated applications is transmitted by the electronic device 101, the user data is not transmitted through a PDU session for a user data transmission or reception service.

[0172] In operation 817, the electronic device 101 may prohibit (or refrain from) sending a PDU session establishment request signal for the execution of a service that is not supported by the network.

[0173] Based on the mapping data, the electronic device 101 can determine that the network 701 connected via the first cellular communication or the second cellular communication supports the SMS service and the MMS service but does not support the transmission or reception of user data (e.g., the second network 701), and can transmit a signal to the node 520 requesting the establishment of a PDU session for the MMS service. However, the electronic device 101 may not transmit a signal to the node 520 requesting the establishment of a separate PDU session for a service other than the MMS service (e.g., a user data transmission or reception service). Thus, the electronic device 101 can reduce unnecessary resource consumption or delay time due to the reception of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to the network 701 that does not support the transmission and / or reception of user data via a PDU session.

[0174] FIG. 9 illustrates an embodiment in which an electronic device transmits UE capability information excluding information related to features not supported by the network, according to an embodiment.

[0175] The network 701 may send a UE capability request message to an electronic device (eg, electronic device 101 of FIG. 6) in operation 911.

[0176] The electronic device 101 may receive a UE Capability Request message from the network 701 during a registration procedure with the network 701 or after registration with the network 701 .

[0177] After an RRC connection with the electronic device 101 is established, the network 701 may send a UE capability request message to the electronic device 101 when UE capability information is required. The UE capability information may indicate information indicating the capabilities of the electronic device 101 related to cellular communication of the electronic device 101. For example, the UE capability information may include information indicating frequency bands that the electronic device 101 can support or information indicating a combination of frequency bands that the electronic device 101 can support. The combination of frequency bands that the electronic device 101 can support may refer to a combination of frequency bands on which the electronic device 101 can simultaneously transmit or receive data. For example, if the electronic device 101 can simultaneously transmit (or receive) a signal via a first frequency band and a signal via a second frequency band, the combination of frequency bands that the electronic device 101 can support may be the first frequency band and the second frequency band.

[0178] The electronic device 101 may transmit UE capability information to the network 701 in operation 913, excluding information related to features that the network 701 does not support.

[0179] The electronic device 101 can transmit UE capability information to the network 701 via the node 520 by receiving a UE capability request message from the network 701 .

[0180] When transmitting UE capability information, the electronic device 101 may transmit UE capability information to the network 701 excluding information not related to the network 701 (or not including information not related to the network 701).

[0181] According to one example, if the network 701 is a non-terrestrial network, the network 701 may not support a communication scheme (e.g., carrier aggregation (CA), E-UTRA-NR Dual connectivity (EN-DC), or Multi-RAT dual connectivity (MR-DC)) that supports transmission or reception of data via multiple frequency bands. If the network 701 does not support transmission or reception of data via multiple frequency bands, the combinations of frequency bands that the electronic device 101 can support may be unnecessary information for the network 701. Therefore, the electronic device 101 can reduce the time (or delay time) required to transmit the UE capability information by transmitting to the network 701 UE capability information that does not include information indicating the combinations of frequency bands supported by the electronic device 101.

[0182] According to one example, if the network 701 is a non-terrestrial network, the network 701 may not support a communication scheme (e.g., carrier aggregation (CA), E-UTRA-NR Dual connectivity (EN-DC), or Multi-RAT dual connectivity (MR-DC)) that supports transmission or reception of data via multiple frequency bands. If the network 701 does not support transmission or reception of data via multiple frequency bands, information indicating whether the electronic device 101 supports different generations of cellular communication schemes may be unnecessary for the network 701. Therefore, the electronic device 101 can reduce the time (or delay time) required to transmit the UE capability information by transmitting to the network 701 UE capability information that does not include information indicating whether the electronic device 101 supports different generations of cellular communication schemes.

[0183] According to one example, if the network 701 is a non-terrestrial network, the network 701 may not support a communication method (e.g., MIMO (multi-input, multi-output)) that supports data transmission or reception using multiple antennas. If the network 701 does not support data transmission or reception via multiple frequency bands, information indicating whether the electronic device 101 supports a communication method that supports data transmission or reception using multiple antennas may be unnecessary information for the network 701. Therefore, the electronic device 101 can reduce the time (or delay time) required to transmit the UE capability information to the network 701 by transmitting UE capability information that does not include information indicating whether the electronic device 101 supports a communication method that supports data transmission or reception using multiple antennas.

[0184] FIG. 10 is an operational flow diagram 1000 illustrating a method of operation of an electronic device according to one embodiment.

[0185] The electronic device (eg, the electronic device 101, communication processor 620 in FIG. 6) can determine whether the network is a non-terrestrial network based on the system information in operation 1010.

[0186] The electronic device 101 can control the communication circuit (e.g., the communication circuit 610 in FIG. 6) to search for a network in order to connect to the network. If the network search is successful, the electronic device 101 can perform a series of procedures to connect to the searched network.

[0187] While searching for a network, the electronic device 101 may receive system information transmitted or broadcast by a node (e.g., satellite 520 in FIG. 5) included in the network (e.g., a non-terrestrial network).

[0188] The electronic device 101 can determine whether the searched network is a non-terrestrial network based on the received system information.

[0189] The system information broadcast by node 520 may include various information. According to one example, the system information may include SIB 1 defined in 3GPP TS.36.331 v15.6. SIB 1 may include identification information of the network in which node 520 is included (e.g., mobile country code (MCC), public land mobile network (PLMN)), information required when connecting (or random access (RA)) to node 520, and / or information indicating that the network is a non-terrestrial network (e.g., cellBarredNTN information element (IE)).

[0190] If the electronic device 101 confirms that the network identification information included in the system information transmitted or broadcast by the node 520 is the specified identification information (e.g., the identification information of a non-terrestrial network), it can confirm that the searched network is a non-terrestrial network.

[0191] The electronic device 101 may determine that the searched network is a non-terrestrial network based on information indicating that the network is a non-terrestrial network included in the system information transmitted or broadcast by the node 520. According to one example, the electronic device 101 may determine that the searched network is a non-terrestrial network based on determining that the cellBarredNTN information element (IE) is indicated as not barred. The electronic device 101 may determine that the searched network is a terrestrial network based on determining that the cellBarredNTN information element (IE) is indicated as barred or based on the cellBarredNTN IE not being included in the system information.

[0192] According to one example, the system information may include SIB 19 defined in 3GPP TS.38.304. SIB 19 may include system information that is transmitted or broadcast when the network in which node 520 is included is a non-terrestrial network, and may include information related to the non-terrestrial network (e.g., altitude information of node 520, movement speed information of node 520). For example, the node transmitting or broadcasting SIB 19 may be a node included in the non-terrestrial network. If the system information transmitted or broadcast by node 520 is SIB 19, the electronic device 101 can confirm that the searched network is a non-terrestrial network.

[0193] The electronic device 101 may, in operation 1020, ascertain network-supported services based on the mapping data.

[0194] The electronic device 101 can determine that the searched network is a non-terrestrial network and, based on the mapping data stored in the memory 630, determine the services that the searched network supports (or does not support).

[0195] The mapping data may include data in which identification information of non-terrestrial networks and information on services supported by the non-terrestrial networks are mapped and stored.

[0196] Referring to Table 1, the mapping data may be data that maps specific networks and the presence or absence of support for services. For example, the electronic device 101 may determine, based on the mapping data, that the first network (991-01) supports the SMS service but does not support the MMS service, the user data transmission and / or reception service, and the satellite-only PDU service. As an example, the electronic device 101 may determine, based on the mapping data, that the second network (992-02) supports the SMS service and the MMS service but does not support the user data transmission and / or reception service and the satellite-only PDU service. As an example, the electronic device 101 may determine, based on the mapping data, that the third network (993-03) supports the SMS service, the MMS service, and the user data transmission and / or reception service but does not support the satellite-only PDU service. As an example, the electronic device 101 may determine, based on the mapping data, that the fourth network (994-04) supports the SMS service, the MMS service, and the satellite-only PDU service but does not support the user data transmission and / or reception service. A satellite-only PDU service is a service for transmitting and / or receiving user data using a PDU that can only be used on a non-terrestrial network, and can refer to a service for transmitting and / or receiving user data using a PDU that cannot be connected via a terrestrial network.

[0197] In operation 1030, the electronic device 101 may prohibit (or refrain from) sending a PDU session establishment request message for a service that the network does not support.

[0198] The electronic device 101 may not transmit a PDU session establishment request message to the network for a service that the network does not support. The electronic device 101 may prohibit the operation of transmitting a PDU session establishment request message to the network for a service that the network does not support. By not transmitting a PDU session establishment request message to the network for a service that the network does not support, the electronic device 101 may prevent unnecessary resource consumption due to the transmission of a PDU session establishment request message.

[0199] According to one example, the electronic device 101 may be coupled to a network via a first cellular communication, which may support SMS transmission or reception via a non-access stratum (NAS), and thus the first cellular communication may not require the establishment of a separate PDU session for SMS service.

[0200] Based on the mapping data, the electronic device 101 may determine that the network connected via the first cellular communication supports only SMS services (e.g., the first network), and may not need to send a signal requesting the establishment of a separate PDU session to the node 520. Thus, the electronic device 101 may reduce unnecessary resource consumption or delay time due to the receipt of a reject message that occurs when sending a signal requesting the establishment of a PDU session to a network that does not support data transmission and / or reception via a PDU session.

[0201] According to one example, the electronic device 101 may be coupled to the network via a second cellular communication, which may require the establishment of a PDU session for SMS transmission or reception.

[0202] The electronic device 101 can determine that the network connected via the second cellular communication supports only the SMS service (e.g., the first network) based on the mapping data, and can transmit a signal to the node 520 requesting the establishment of a PDU session for the SMS service. However, the electronic device 101 does not need to transmit a signal to the node 520 requesting the establishment of a separate PDU session for a service other than the SMS service. Thus, the electronic device 101 can reduce unnecessary resource consumption or delay time due to the reception of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to a network that does not support data transmission and / or reception via a PDU session.

[0203] Based on the mapping data, the electronic device 101 can determine that the network connected via the first cellular communication or the second cellular communication supports the SMS service and the MMS service but does not support the transmission or reception of user data (e.g., the second network), and can transmit a signal to the node 520 requesting the establishment of a PDU session for the MMS service. However, the electronic device 101 may not transmit a signal to the node 520 requesting the establishment of a separate PDU session for a service other than the MMS service (e.g., a user data transmission or reception service). Thus, the electronic device 101 can reduce unnecessary resource consumption or delay time due to the reception of a reject message that occurs when transmitting a signal requesting the establishment of a PDU session to a network that does not support the transmission and / or reception of user data via a PDU session.

[0204] Based on the mapping data, the electronic device 101 can determine that the network connected via the first cellular communication or the second cellular communication supports the SMS service, the MMS service, and the transmission or reception of user data (e.g., a third network), and can transmit a signal requesting establishment of a PDU session for the MMS service and / or a signal requesting establishment of a PDU session for a user data transmission or reception service to the node 520. After transmitting the signal requesting establishment of a PDU session for a user data transmission or reception service, the electronic device 101 can perform a series of procedures for establishing a PDU session for a user data transmission or reception service. The electronic device 101 can transmit data to the network or receive data from the network via the PDU session for the user data transmission or reception service.

[0205] However, the electronic device 101 may prohibit applications other than the designated applications from transmitting and / or receiving user data. The electronic device 101 may pre-designate applications that can transmit or receive data via the non-terrestrial network, and the electronic device 101 may restrict applications other than the designated applications from transmitting or receiving user data. According to one example, the electronic device 101 may not transmit user data generated by applications other than the designated applications through a PDU session for a user data transmission or reception service.

[0206] The electronic device 101 may determine, based on the mapping data, that the network connected via the first cellular communication or the second cellular communication supports SMS service, MMS service, and transmission or reception of user data via a satellite-dedicated PDU (e.g., a fourth network), and may transmit a signal requesting establishment of a satellite-dedicated PDU session to the node 520. The electronic device 101 may be prohibited from transmitting a signal requesting establishment of a PDU session for transmission or reception of user data. After transmitting a signal requesting establishment of a satellite-dedicated PDU session, the electronic device 101 may perform a series of procedures for establishing a satellite-dedicated PDU session. The electronic device 101 may transmit data to the network or receive data from the network via the satellite-dedicated PDU session.

[0207] However, the electronic device 101 may prohibit applications other than the designated applications from transmitting and / or receiving user data. The electronic device 101 may pre-designate applications that are allowed to transmit or receive data via the non-terrestrial network, and the electronic device 101 may restrict applications other than the designated applications from transmitting or receiving user data. According to one example, the electronic device 101 may not transmit user data generated by applications other than the designated applications via a satellite-only PDU session.

[0208] As described above, the electronic device 101 can reduce unnecessary resource consumption or delay time due to receiving a reject message that occurs when transmitting a signal requesting the establishment of a PDU session for a service that is not supported by the non-terrestrial network by not transmitting a message to the node 520 requesting the establishment of a PDU session for a service that is not supported by the non-terrestrial network.
