Description

Technical Field

[0001] This disclosure relates to an electronic device for performing a handover and a method for operating the electronic device. Background Technology

[0002] With the latest developments in mobile communication technology, portable terminals with various functions are widely used, and efforts are being made to develop 5G communication systems to meet the ever-increasing demand for wireless data traffic. To achieve higher data transmission rates, in addition to the high-frequency bands used for 5G and LTE, the implementation of 5G communication systems in the ultra-high frequency band is also being considered, thus providing even higher transmission rates.

[0003] Schemes for implementing 5G communication include Standalone (SA) and Non-Standalone (NSA) schemes. Under the SA scheme, the UE can perform radio access based on the New Radio (NR) Radio Access Technology (RAT) and register in the 5G Core (5GC) core network. Under the NSA scheme, the UE can perform radio access based on the Evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access (EUTRA) RAT and register in the Evolved Packet Core (EPC) core network. After registration in the EPC, the UE can send / receive data based on the EUTRA RAT and / or the NR RAT, using dual connectivity. The technology used by the UE to send / receive data based on different types of RATs can be called dual connectivity. According to the 5G NSA scheme, dual connectivity, as proposed in 3GPP Release 12, can be implemented in such a way that the EUTRA-based base station is used as the primary node, and the NR-based base station is used as the secondary node. Summary of the Invention

[0004] Technical issues

[0005] The UE can support both SA and NSA modes. In NSA mode, the UE can use different types of RATs to send / receive data, and in this case, heat generation or a significant increase in power consumption may occur. Problems may arise when entering NSA mode if the UE is in a high-temperature state or if the battery power level is low. Furthermore, the UE may need to operate in SA mode even under high-temperature conditions or with low battery power levels. For example, the UE may need to perform inter-RAT handover even under high-temperature conditions or with low battery power levels.

[0006] According to various embodiments, an electronic device and a method for operating the electronic device are provided, wherein the electronic device and method can perform measurements on frequencies considered to support SA mode under a dual-connection (DC) restricted state, and can not perform measurements on frequencies considered to support NSA mode.

[0007] Technical solutions

[0008] According to various embodiments, an electronic device may include at least one processor configured to support a first radio access technology (RAT) and a second RAT, wherein the at least one processor is configured to: receive, based on the first RAT, a radio resource control (RRC) reconfiguration message including a measurement object (MO) from a network; and, based on the dual connectivity (DC) of the first RAT and the second RAT being identified as restricted, perform measurements on at least one first frequency among at least one frequency based on the second RAT identified based on the MO that satisfies a condition associated with an independent (SA) mode, and suppress the performance of measurements on at least one other second frequency among the at least one frequency that does not satisfy the condition.

[0009] According to various embodiments, a method for operating an electronic device configured to support a first radio access technology (RAT) and a second RAT may include: receiving a radio resource control (RRC) reconfiguration message from a network, including a measurement object (MO), based on the first RAT; performing a measurement on at least one first frequency among at least one frequency based on the second RAT identified as restricted, which satisfies a condition associated with an independent (SA) mode, based on the MO; and suppressing the performance of a measurement on at least one second frequency among the at least one frequency that does not satisfy the condition.

[0011] Beneficial effects

[0012] Various embodiments may provide an electronic device and a method for operating it, wherein, in a DC-limited state, measurements can be performed on frequencies believed to support SA mode, and measurements may not be performed on frequencies believed to support NSA mode. Therefore, in a DC-limited state, operation can be restricted to NSA mode, and inter-RAT handover for SA mode can be performed. Attached Figure Description

For example, when electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or may be implemented as part of the main processor 121.

The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to an embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0034] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display device 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector.

[0041] The power management module 188 manages the power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0042] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0043] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0044] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic devices (e.g., electronic device 104), or network systems (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0045] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192).

[0047] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0048] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

[0049] Figure 2a This is a block diagram 200 of an electronic device 101 for supporting conventional network communication and 5G network communication according to various embodiments. (See reference...) Figure 2aThe electronic device 101 may include a first communication processor (e.g., processing circuitry) 212, a second communication processor (e.g., processing circuitry) 214, a first radio frequency integrated circuit (RFIC) 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, a first radio frequency front-end (RFFE) 232, a second RFFE 234, a first antenna module 242, a second antenna module 244, a third antenna module 246, and an antenna 248. The electronic device 101 may further include a processor 120 and a memory 130. The second network 199 may include a first cellular network 292 and a second cellular network 294. According to an embodiment, the electronic device 101 may further include... Figure 1 At least one of the components shown is included, and the second network 199 may further include at least another network. According to an embodiment, the first communication processor 212, the second communication processor 214, the first RFIC 222, the second RFIC 224, the fourth RFIC 228, the first RFFE 232, and the second RFFE 234 may configure at least a portion of the wireless communication module 192. According to an embodiment, the fourth RFIC 228 may be omitted, or may be included as part of the third RFIC 226.

[0050] The first communication processor 212 may include various processing circuitry and establish a communication channel in a frequency band for wireless communication with the first cellular network 292, and may support conventional network communication performed through the established communication channel. According to various embodiments, the first cellular network may be a conventional network, including second-generation (2G), 3G, 4G, or Long Term Evolution (LTE) networks. The second communication processor 214 may establish a communication channel corresponding to a specified frequency band (e.g., approximately 6 GHz to 60 GHz) in the frequency band for wireless communication with the second cellular network 294, and may support 5G network communication performed through the established communication channel. According to various embodiments, the second cellular network 294 may be a 5G network as defined in 3GPP. Additionally, according to embodiments, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another specified frequency band (e.g., approximately 6 GHz or lower) in the frequency band for wireless communication with the second cellular network 294, and may support 5G network communication performed through the established communication channel.

[0051] The first communication processor 212 can send data to or receive data from the second communication processor 214. For example, data that has been classified as being transmitted via the second cellular network 294 can be changed to be transmitted via the first cellular network 292. In this case, the first communication processor 212 can receive the transmitted data from the second communication processor 214. For example, the first communication processor 212 can send data to or receive data from the second communication processor 214 via an inter-processor interface 213. The inter-processor interface 213 can be implemented as, for example, a Universal Asynchronous Receiver / Transmitter (UART) (e.g., High Speed ​​UART (HS-UART) or a Peripheral Component Interconnect Bus Fast (PCIe) interface), but its type is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 can use, for example, shared memory to exchange control information and packet data information. The first communication processor 212 can send various information to or receive various information from the second communication processor 214, such as sensing information, information about output strength, and resource block (RB) allocation information.

[0052] Depending on the implementation, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 can send data to or receive data from the second communication processor 214 via the processor 120 (e.g., an application processor). For example, the first communication processor 212 and the second communication processor 214 can send data to or receive data from each other via the processor 120 (e.g., an application processor) and an HS-UART interface or a PCIe interface, but the type of interface is not limited. Alternatively, the first communication processor 212 and the second communication processor 214 can use the processor 120 (e.g., an application processor) and shared memory to exchange control information and packet data information.

[0053] According to embodiments, the first communication processor 212 and the second communication processor 214 can be implemented in a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 can be configured together with the processor 120, the auxiliary processor 123, or the communication module 190 in a single chip or a single package. For example, as... Figure 2b As shown, the integrated communication processor 260 can support both functions for communicating with the first cellular network 292 and functions for communicating with the second cellular network 294.

[0054] The first RFIC 222 can, during transmission, convert the baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal with a frequency of approximately 700 MHz to approximately 3 GHz, which is used in the first cellular network 292 (e.g., a conventional network). During reception, the RF signal can be obtained from the first cellular network 292 (e.g., a conventional network) via an antenna (e.g., a first antenna module 242), and the signal can be preprocessed via an RFFE (e.g., a first RFFE 232). The first RFIC 222 can convert the preprocessed RF signal back into a baseband signal so that the preprocessed RF signal can be processed by the first communication processor 212.

[0055] The second RFIC 224 can, during transmission, convert the 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) within the Sub6 frequency band (e.g., approximately 6 GHz or lower) used in the second cellular network 294 (e.g., a 5G network). During reception, the 5G Sub6 RF signal can be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., a second antenna module 244), and the signal can be preprocessed via an RFFE (e.g., a second RFFE 234). The second RFIC 224 can convert the preprocessed 5G Sub6 RF signal back into a baseband signal so that the preprocessed 5G Sub6 RF signal can be processed by the corresponding communication processor in the first communication processor 212 or the second communication processor 214.

[0056] The third RFIC 226 can convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, a 5G Above6 RF signal) within the 5G Above6 frequency band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network 294 (e.g., a 5G network). Upon reception, the 5G Above6 RF signal can be obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248), and the signal can be preprocessed by the third RFFE 236. The third RFIC 226 can convert the preprocessed 5G Above6 RF signal back into a baseband signal so that the preprocessed 5G Above6 RF signal can be processed by the second communication processor 214. According to an embodiment, the third RFFE 236 can be configured as part of the third RFIC 226.

[0057] According to an embodiment, electronic device 101 may include a fourth RFIC 228 separate from the third RFIC 226 or at least a portion thereof. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, an IF signal) within an intermediate frequency band (e.g., approximately 9 GHz to 11 GHz), and then transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from a second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248), and the signal may be converted back into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal back into a baseband signal so that the IF signal can be processed by the second communication processor 214.

[0058] According to embodiments, the first RIFC 222 and the second RFIC 224 can be implemented as at least part of a single chip or a single package. According to various embodiments, such as Figure 2a or Figure 2b As shown, when the first RFIC 222 and the second RFIC 224 are implemented as a single chip or a single package, the first RFIC and the second RFIC can be implemented as an integrated RFIC. In this case, the integrated RFIC can be connected to the first RFFE 232 and the second RFFE 234 to convert the baseband signal into a signal within the frequency band supported by the first RFFE 232 and / or the second RFFE 234, and send the converted signal to one of the first RFFE 232 and the second RFFE 234. According to an embodiment, the first RFFE 232 and the second RFFE 234 can be implemented as at least a portion of a single chip or a single package. According to an embodiment, at least one antenna module in the first antenna module 242 or the second antenna module 244 can be omitted or combined with another antenna module to process RF signals within multiple corresponding frequency bands.

[0059] According to an embodiment, the third RFIC 226 and the antenna 248 can be arranged on the same substrate to configure the third antenna module 246. For example, the wireless communication module 192 or the processor 120 can be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC 226 can be disposed in a portion of a second substrate (e.g., a sub-PCB) separate from the first substrate (e.g., the lower surface), and the antenna 248 can be disposed in another portion of the second substrate (e.g., the upper surface) to configure the third antenna module 246. By arranging the third RFIC and the antenna on the same substrate, the length of the transmission line between the third RFIC 226 and the antenna 248 can be reduced. Therefore, for example, signal loss (e.g., attenuation) through the transmission line in the high-frequency band (e.g., from about 6 GHz to about 60 GHz) used for 5G network communication can be reduced. Therefore, the electronic device 101 can improve the quality or speed of communication with the second cellular network 294 (e.g., a 5G network).

[0060] According to an embodiment, antenna 248 can be configured as an antenna array including multiple antenna elements that can be used for beamforming. In this case, the third RFIC 226 may include multiple phase shifters 238 corresponding to the multiple antenna elements, for example, as part of a third RFFE 236. During transmission, each of the multiple phase shifters 238 can shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device 101 via its corresponding antenna element. During reception, each of the multiple phase shifters 238 can shift the phase of a 5G Above6 RF signal already received from the external source to the same or substantially the same phase via its corresponding antenna element. This process enables transmission or reception via beamforming between the electronic device 101 and the external source.

[0061] The second cellular network 294 (e.g., a 5G network) can operate independently of the first cellular network 292 (e.g., a legacy network) (e.g., standalone (SA) operation), or it can operate while connected to the first cellular network (e.g., non-standalone (NSA) operation). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NGRAN)) without a core network (e.g., a next-generation core (NGC)). In this case, the electronic device 101 can access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., an evolved packet core (EPC)). Protocol information for communicating with the legacy network (e.g., LTE protocol network) or protocol information for communicating with the 5G network (e.g., new radio (NR) protocol information) can be stored in memory 130 and can be accessed by another component (e.g., protocol 120, the first communication protocol 212, or the second communication protocol 214).

[0062] Figure 3a , Figure 3b and Figure 3c This is a diagram illustrating wireless communication systems providing conventional and / or 5G communication networks according to various embodiments. Reference Figure 3a , Figure 3b and Figure 3c Each of network environments 300a to 300c may include at least one of a traditional network and a 5G network. The traditional network may include, for example, a 3GPP standard 4G or LTE base station 340 (e.g., an eNodeB (eNB)) supporting radio access for electronic device 101, and an evolved packet core (EPC) 342 managing 4G communications. The 5G network may include, for example, a new radio (NR) base station 350 (e.g., a gNB (gNodeB)) supporting radio access for electronic device 101, and a fifth-generation core (5GC) 352 managing 5G communications for electronic device 101.

[0063] According to various embodiments, electronic device 101 can send or receive control messages and user data via conventional communication and / or 5G communication. Control messages may include, for example, messages related to at least one of security control, bearer establishment, authentication, registration, or mobility management of electronic device 101. User data may indicate user data other than control messages sent or received between electronic device 101 and core network 330 (e.g., EPC 342).

[0064] refer to Figure 3aAccording to the embodiment, the electronic device 101 can use at least a portion of a conventional network (e.g., LTE base station 340 or EPC 342) to send or receive at least one of control messages or user data from at least a portion of a 5G network (e.g., NR base station 350 or 5GC 352).

[0065] According to various embodiments, network environment 300a may include a network environment that provides wireless communication dual connectivity (DC) to LTE base station 340 and NR base station 350, and enables the sending or receiving of control messages to or from electronic device 101 via a core network 330 of EPC 342 or 5GC 352.

[0066] According to various embodiments, in a DC environment, one of the LTE base station 340 or NR base station 350 can be operated as a master node 310, and the other base station can be operated as a secondary node (SN) 320. MN 310 can be connected to the core network 230 to send or receive control messages thereto. MN 310 and SN 320 can be connected to each other via network interfaces to send or receive messages relating to the management of radio resources (e.g., communication channels).

[0067] According to various embodiments, MN 310 can be configured by LTE base station 340, SN 320 can be configured by NR base station 350, and core network 330 can be configured by EPC 342. For example, control messages can be sent or received through LTE base station 340 and EPC 342, and user data can be sent or received through at least one of LTE base station 340 or NR base station 350.

[0068] According to various embodiments, MN 310 can be configured by NR base station 350, SN 320 can be configured by LTE base station 340, and core network 330 can be configured by 5GC 352. For example, control messages can be sent or received through NR base station 350 and 5GC 352, and user data can be sent or received through at least one of LTE base station 340 or NR base station 350.

[0069] refer to Figure 3b According to various embodiments, the 5G network can be configured by NR base station 350 and 5GC 352, and can independently send or receive control messages and user data to or from electronic device 101.

[0070] refer to Figure 3cAccording to various embodiments, conventional networks and 5G networks can independently provide data transmission or reception. For example, electronic devices 101 and EPC 342 can send or receive control messages and user data to or from each other via LTE base station 340. As another example, electronic devices 101 and 5GC 352 can send or receive control messages and user data to or from each other via NR base station 350.

[0071] According to various embodiments, electronic device 101 may be registered with at least one of EPC 342 or 5GC 352 in order to send or receive control messages to or from it.

[0072] According to various embodiments, EPC 342 or 5GC 352 can interact to manage communications of electronic device 101. For example, movement information of electronic device 101 can be sent or received through the interface between EPC 342 and 5GC 352.

[0073] As described above, the dual connectivity via LTE base station 340 and NR base station 350 can be named E-UTRA New Radio Dual Connectivity (EN-DC).

[0074] Figure 4 This is a flowchart illustrating a method of operating an electronic device according to various embodiments. (Refer to...) Figure 5 describe Figure 4 Examples of implementations. Figure 5 Multiple base stations and electronic devices according to various embodiments are shown.

[0075] According to various embodiments, in operation 401, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive a Radio Resource Control (RRC) reconfiguration message including a Measurement Object (MO) based on a first RAT. The first RAT can be E-UTRA or NR. Figure 4In the embodiments described, electronic device 101 may have been registered in EPC based on E-UTRA, or it may have been registered in 5GC based on NR, and for example, electronic device 101 may be in the RRC_CONNECTED state, but this disclosure is not limited thereto. Electronic device 101 may be configured to report measurement information according to the measurement configuration provided by the network. For example, if electronic device 101 is in the RRC_CONNECTED state, the network may use dedicated signaling means to provide message configuration, such as an RRC reconfiguration message. According to various embodiments, when the first RAT is E-UTRA, the RRC reconfiguration message may be an RRCConnectionReconfiguration message or an RRCConnectionResume message following, for example, 3GPP Technical Specification (TS) 36.331. When the first RAT is NR, the RRC reconfiguration message may be an RRCReconfiguration message following, for example, 3GPP TS 38.331. However, this disclosure is not limited thereto.

[0076] According to various embodiments, the MO may include information associated with the frequency (or cell (e.g., a cell for a first RAT and / or a cell for a second RAT)) that requires the user equipment (UE) to perform measurements. The cell-associated information may include at least one of frequency channel number, cell identification information (e.g., physical cell identifier (PCI)), a blacklist, or a cell-specific offset value. For example, when the first RAT is E-UTRA, the second RAT may be NR, and the MO may include, for example, a single NR carrier frequency. Similarly, when the first RAT is NR, the second RAT may be E-UTRA, and the MO may include, for example, a single E-UTRA carrier frequency. The RRC reconfiguration message may include a reporting configuration and, for example, reporting conditions for performing a measurement report (MR). The RRC reconfiguration message may include at least one of a measurement ID for identifying the MO, a configuration indicating the number of values ​​the UE needs to measure, or a measurement interval associated with a measurement period.

[0077] According to various embodiments, in operation 403, electronic device 101 can identify that dual connectivity is restricted. In various embodiments, whether DC is restricted can be determined by, for example, processor 120, and processor 120 can transmit the determined result to a communication processor (e.g., at least one of a first communication processor 212, a second communication processor 214, or an integrated communication processor 260). In various embodiments, the communication processor can be configured to determine whether DC is restricted. The communication processor can determine whether DC is restricted based on information transmitted from processor 120, and / or can determine whether DC is restricted based on information obtained by the communication processor.

[0078] For example, a DC-limited state could correspond to a situation where the remaining power of the battery in electronic device 101 is equal to or less than a threshold remaining power (e.g., 15%). The rate of battery depletion (e.g., the amount of battery power reduced per unit time) when using DC can be greater than the rate of battery depletion when not using DC. Therefore, DC limiting can be configured to conserve battery power when the remaining battery power is equal to or less than the threshold remaining power.

[0079] For example, a DC-limited state may correspond to a situation where the current and / or predicted transmit and / or receive data rate of electronic device 101 is equal to or less than a threshold data rate (e.g., 30 Mbps). With the use of DC, the data rate may increase. However, when the current and / or predicted data rate is relatively low, the benefits of using DC are less. Therefore, DC limiting can be configured when the current and / or predicted transmit and / or receive data rate is equal to or less than the threshold data rate. A situation where the current and / or predicted transmit and / or receive data rate is equal to or less than the threshold data rate may correspond to, for example, VoIP (e.g., Voice over LTE (VoLTE) or Voice over NR (VoNR)) being running, or the screen of electronic device 101 being off. The situation where the current and / or predicted transmit and / or receive data rate is equal to or less than the threshold data rate can be identified based on, for example, the type of application running in the foreground and / or background. The situation where the current and / or predicted transmit and / or receive data rate is equal to or less than the threshold data rate can also be identified based on, for example, the scheduling rate of uplink and / or downlink resources. For example, the scheduling rate can be measured based on the number of downlink control indicators (DCIs) (e.g., DCI format 0 or DCI format 1) received per reference time (e.g., one second). There are no restrictions on the conditions associated with the data rate.

[0080] For example, a DC-limited state may correspond to a situation where the current temperature of electronic device 101 is equal to or greater than a threshold temperature (e.g., 39°C). The heat generated from electronic device 101 when using DC may be greater than the heat generated when not using DC. When using DC, the temperature may continue to rise, which could damage electronic device 101. Therefore, DC limiting can be configured when the current temperature is equal to or greater than the threshold temperature. The current temperature of electronic device 101 may include, for example, the current temperature of at least one component included in electronic device 101 (e.g., processor 120, first communication processor 212, second communication processor 214, integrated communication processor 260, and / or wireless communication module 192). For example, electronic device 101 can be monitored by a temperature sensor (e.g., Figure 1 The sensor module 176 in the device measures the current temperature of the electronic device 101. The temperature sensor is included in or near the surface of at least one element.

[0081] For example, a DC-limited state could be a situation where a Subscriber Identity Module (SIM) is used that does not require the use of an Internet Packet Data Network (PDN) (or Data Network Name (DNN)). Electronic device 101 can support multiple SIMs. In the case of multiple SIMs supporting Dual SIM Dual Standby (DSDS) mode, other SIMs can be in standby mode while RF resources are used to transmit or receive data associated with one of the multiple SIMs. One of the multiple SIMs can be configured to process data packets (e.g., packets associated with an Internet PDN), and another can be configured to process voice packets (e.g., packets associated with an IMSPDN). Voice packets have a relatively small size and therefore may offer less benefit when using DC. Therefore, in the case of multiple SIMs operating in DSDS mode, DC limitation can be configured when operating the SIM associated with voice packet processing.

[0082] exist Figure 4 In this embodiment, electronic device 101 identifies that the DC is restricted after receiving the RRC reconfiguration message. However, this illustration corresponds only to an example, and electronic device 101 may also receive the RRC reconfiguration message while the DC is restricted. Furthermore, those skilled in the art will understand that the order of the flowcharts according to the various embodiments is not limited.

[0083] According to various embodiments, when electronic device 101 is in a DC-limited state, in operation 405, electronic device 101 can determine whether at least one frequency based on the second RAT, identified by MO, satisfies a condition associated with SA mode. The condition associated with SA mode may be, for example, a condition associated with whether a cell having the corresponding frequency can support SA mode. In one example, the condition associated with SA may be the existence of a history of supporting SA mode via the corresponding frequency. In one example, the condition associated with SA may be the absence of a history of supporting NSA mode via the corresponding frequency. In one example, the condition associated with SA mode may be that the corresponding frequency is included in System Information Block (SIB) 24 provided by a base station associated with the first RAT (e.g., an eNB in ​​the case of E-UTRA). In one example, the condition associated with SA mode may be that the corresponding frequency is included in System Information Block (SIB) 1 provided by a base station associated with the second RAT (e.g., a gNB in ​​the case of NR).

[0084] refer to Figure 5 For example, electronic device 101 may have already registered in a core network (e.g., EPC) corresponding to a first RAT (e.g., E-UTRA) using the first base station 501 as its serving cell. Electronic device 101 may have already established an RRC connection with the first base station 501 (e.g., eNB) based on the first RAT (e.g., E-UTRA). Electronic device 101 can receive an RRC reconfiguration message 521 from the first base station 501. Electronic device 101 can identify at least one frequency associated with the second RAT (e.g., NR) from the MO included in the RRC reconfiguration message 521. For example, the MO may include at least one single NR carrier frequency (e.g., ARFCN#1, ARFCN#2, or ARFCN#3). ARFCN#1 may be, for example, the absolute radio frequency channel number (ARFCN) of a second base station 503 (e.g., gNB) based on the second RAT (e.g., NR). ARFCN#2 may be, for example, the ARFCN of a third base station 505 (e.g., gNB) based on the second RAT (e.g., NR). ARFCN#3 can be an ARFCN of a fourth base station 507 (e.g., gNB) based on, for example, a second RAT (e.g., NR). Neighboring base stations 503, 505, and 507 can transmit synchronization signals 523, 525, and 527 (e.g., SSB). Those skilled in the art will understand that, in the case where the first RAT is NR and the second RAT is E-UTRA, neighboring base stations 503, 505, and 507 can transmit reference signals (e.g., CSI-RS).

[0085] Refer again Figure 4According to various embodiments, when the conditions associated with the SA mode are met (operation 405 "Yes"), in operation 407, the electronic device 101 can perform a measurement of at least one first frequency for which the conditions are met. The measurement may indicate measurements of reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), received signal strength indicator (RSSI), and / or signal-to-noise ratio (SNR) at the time when measuring a signal (e.g., a synchronization signal and / or a reference signal) corresponding to the first frequency. However, this disclosure is not limited thereto. When the conditions associated with the SA mode are not met (operation 405 "No"), in operation 409, the electronic device 101 can suppress the execution of a measurement of at least one second frequency for which the conditions are not met. For example, in Figure 5 In this embodiment, ARFCN#1 may be included in SIB-24 from the first base station 501, and ARFCN#2 and ARFCN#3 may be managed to have a history of performing DC. In this case, the electronic device 101 may determine that ARFCN#1 meets the conditions associated with SA, and that ARFCN#2 and ARFCN#3 do not meet the conditions associated with SA. The electronic device 101 may perform a measurement of the synchronization signal 523 corresponding to ARFCN#1. The electronic device 101 may suppress the execution of measurements of the synchronization signals 525 and 527 corresponding to ARFCN#2 and ARFCN#3. At the time of measuring the synchronization signals 525 and 527, the electronic device 101 may suppress the execution of operations for signal measurement (e.g., switching operations for connection to the RX antenna, and / or measurements of RSRP, RSRQ, SNR, or SINR).

[0086] According to various embodiments, electronic device 101 can execute a measurement report when reporting conditions for at least one first frequency (e.g., ARFCN#1) are met. The network can determine a handover to the second base station 503 based on the measurement report. In this case, electronic device 101 can execute a handover from the first base station 501 to the second base station 503 (e.g., inter-RAT handover). Measurements for at least one second frequency (e.g., ARFCN#2 or ARFCN#3) may not be performed, thereby preventing and / or mitigating the addition of a second cell group (SCG) for DCs used by the third base station 505 and the fourth base station 507. Therefore, DCs may not be performed, and thus problems caused by DC usage under DC-limited conditions can be prevented and / or mitigated. Those skilled in the art will understand that electronic device 101 not measuring a specific frequency can be replaced by, for example, suppressing the execution of a measurement report even if reporting conditions are met after measurement.

[0087] Figure 6a This is a flowchart illustrating the operation methods of an electronic device and an eNB according to various embodiments.

[0088] According to various embodiments, in operation 611, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive SIB 24 from eNB 600. eNB 600 can send SIB 24 to electronic device 101 to enable electronic device 101 to perform cell reselection. In 3GPP TS 36.331, SIB 24 is described as an Information Element (IE) of system information type 24. SIB 24 may include information related to NR neighboring cells and inter-cell RATs used for cell reselection, such as information about NR frequencies. SIB 24 may include cell reselection parameters common to frequencies. SIB 24 may include, for example, information about NR frequencies supporting SA mode (e.g., ARFCN). When a cell associated with eNB 600 is pre-occupied, electronic device 101 can identify information about NR cells supporting SA mode around said cell. According to various embodiments, the electronic device 101 can identify frequencies around it that support SA modes based on information included in SIB 24.

[0089] Figure 6b This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0090] According to various embodiments, in operation 621, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive SIB 24 from a network (e.g., eNB 600). For example, Table 1 shows examples of SIB 24 received by electronic device 101.

[0091] Table 1

[0092]

[0093] SIB 24, based on the examples in Table 1, may include ARFCN “627264” as a frequency for a neighboring NR cell (for which cell reselection of the network (e.g., eNB 600) is enabled), for example, as an NR frequency supporting SA mode.

[0094] According to various embodiments, in operation 623, electronic device 101 can receive an RRC reconfiguration message including an MO from the network. Those skilled in the art will understand that the order of operations 621 and 623 is not limited. For example, Table 2 shows examples of RRC reconfiguration messages received by electronic device 101.

[0095] Table 2

[0096]

[0097] The RRC reconfiguration message for the example in Table 2 may include ARFCN “636654” and “627264” as the frequencies to be measured.

[0098] According to various embodiments, in operation 625, electronic device 101 can determine whether at least one frequency based on the second RAT and identified by MO is included in SIB 24. If it is determined that at least one frequency based on the second RAT and identified by MO is included in SIB 24 (operation 625 "Yes"), in operation 627, electronic device 101 can perform a measurement of at least one first frequency included in SIB 24. If it is not determined that at least one frequency based on the second RAT and identified by MO is included in SIB 24 (operation 625 "No"), in operation 629, electronic device 101 can suppress the execution of a measurement of at least one second frequency not included in SIB 24. For example, based on SIB 24 according to the example in Table 1 and the RRC reconfiguration message according to the example in Table 2, electronic device 101 can identify that ARFCN "627264" is included in SIB 24 and ARFCN "636654" is not included in SIB 24. Electronic device 101 can perform measurements on ARFCN "627264" identified as included in SIB 24. If the measurement result for ARFCN "627264" is determined to meet reporting conditions, electronic device 101 can perform a measurement report (MR). Based on the measurement report, the network can determine a handover from electronic device 101 to the cell corresponding to ARFCN "627264", and electronic device 101 can perform the handover. Electronic device 101 can suppress the execution of measurements on ARFCN "636654" identified as not included in SIB 24. Electronic device 101 has not yet performed measurements, and therefore can suppress the execution of MR for ARFCN "636654". Therefore, the addition of SCG associated with the cell corresponding to ARFCN "636654" can be prevented, and thus DC can be limited.

[0099] Figure 7 This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0100] According to various embodiments, in operation 701, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive an RRC reconfiguration message including the MO. In operation 703, electronic device 101 can determine, by referring to pre-stored information, whether at least one frequency based on the second RAT identified by the MO satisfies the conditions associated with the SA mode.

[0101] For example, Table 3 shows an example of information pre-stored in electronic device 101.

[0102] Table 3

[0103] AFRCN SA support 627264 yes 629952 yes 643334 no

[0104] Electronic device 101 can manage the information shown in Table 3 based on whether SA or NSA is used at a specific frequency. Electronic device 101 can obtain the information shown in Table 3 based on its existing operation, and / or can receive the information from a network or service provider management server. Those skilled in the art will understand that the PLMN ID, frequency band, and / or cell ID corresponding to the AFRCN can be further added to the information in Table 3. When additional information is added, electronic device 101 can compare the additional information with information based on MO identification to determine whether SA mode is supported. Table 3 is only an example, and electronic device 101 can also manage pre-stored information in different formats. For example, electronic device 101 can also store frequencies that support SA mode (e.g., ARFCN), and / or also store frequencies that support NSA mode (e.g., ARFCN).

[0105] According to various embodiments, if it is determined by referring to pre-stored information that at least one frequency based on the second RAT identified by the MO satisfies the conditions associated with the SA mode (operation 703 "Yes"), then in operation 705, the electronic device 101 can perform a measurement on at least one first frequency that satisfies the conditions. If it is determined by referring to pre-stored information that at least one frequency based on the second RAT identified by the MO does not satisfy the conditions associated with the SA mode (operation 703 "No"), then in operation 707, the electronic device 101 can suppress the execution of a measurement on at least one second frequency that does not satisfy the conditions. For example, the electronic device 101 can use information as shown in Table 3 to determine whether an ARFCN included in the MO supports the SA mode. If the MO identifies ARFCNs "627264" and "643334", then the electronic device 101 can identify, based on Table 3, that ARFCN "627264" supports the SA mode and ARFCN "643334" does not support the SA mode. The electronic device 101 can perform a measurement of ARFCN "627264" and can suppress the performance of a measurement of ARFCN "643334".

[0106] For example, when electronic device 101 manages a list of ARFCNs supporting SA mode, electronic device 101 can perform measurements on ARFCNs included in the list among those identified by MO, and can suppress the execution of measurements on ARFCNs not included in the list. For example, when electronic device 101 manages a list of ARFCNs supporting NSA mode, electronic device 101 can perform measurements on ARFCNs not included in the list among those identified by MO, and can suppress the execution of measurements on ARFCNs included in the list.

[0107] Figures 8a to 8c This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0108] refer to Figure 8aAccording to various embodiments, in operation 801, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive an RRC reconfiguration message including the MO. In operation 803, electronic device 101 can perform a measurement based on the MO. In operation 805, electronic device 101 can execute a measurement report based on the measurement result satisfying the conditions of a measurement report. For example, if a B1 event is identified as satisfied, electronic device 101 can execute a measurement report, but there are no restrictions on the reporting conditions. In operation 807, electronic device 101 can receive an RRC reconfiguration message related to SCG addition configuration. For example, the network can receive a measurement report from electronic device 101 and can determine, based on the received measurement report, to perform SCG addition for the cell corresponding to the measurement report. In this case, the network can send an RRC reconfiguration message including the SCG addition configuration to electronic device 101. When electronic device 101 is not in a DC-restricted state, it can perform a RACH procedure on the cell corresponding to the SCG addition based on the received RRC reconfiguration message. Based on the RACH procedure, electronic device 101 can also perform DC. In operation 809, electronic device 101 can store at least one frequency associated with the SCG addition configuration. For example, electronic device 101 can add information related to the corresponding frequency not supporting SA mode to the information shown in Table 3. For example, electronic device 101 can also add the corresponding frequency to the list of frequencies supporting NSA mode.

[0109] refer to Figure 8bAccording to various embodiments, in operation 811, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive an RRC reconfiguration message including MO. In operation 813, electronic device 101 can perform a measurement based on MO. In operation 815, electronic device 101 can execute a measurement report based on the measurement results meeting the conditions of a measurement report. For example, if a B1 event is identified, electronic device 101 can execute a measurement report, but there are no restrictions on the reporting conditions. In operation 817, electronic device 101 can receive a handover command. For example, the network can receive a measurement report from electronic device 101 and can determine, based on the received measurement report, to perform a handover to the cell corresponding to the measurement report. In this case, the network can send a handover command to electronic device 101. Electronic device 101 can perform a handover procedure based on the received handover command. In operation 819, electronic device 101 may store at least one frequency associated with the handover command. For example, electronic device 101 may add information related to the corresponding frequency supporting SA mode to the information shown in Table 3. For example, electronic device 101 may also add the corresponding frequency to the list of frequencies supporting NSA mode.

[0110] refer to Figure 8c According to various embodiments, in operation 821, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can perform a cell selection operation. For example, electronic device 101 can perform the cell selection operation based on a second RAT. In operation 823, electronic device 101 can store at least one frequency associated with the second RAT identified during the cell selection operation. For example, electronic device 101 can manage frequencies corresponding to cells operable as serving cells to support SA mode. Figures 8a to 8c It applies only to instances and there are no restrictions on the configuration used to determine whether SA mode and NSA mode are supported.

[0111] Figure 9 This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0112] According to various embodiments, in operation 901, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive an RRC reconfiguration message including the MO. In operation 903, electronic device 101 can identify at least one frequency based on a second RAT based on the MO. In operation 905, electronic device 101 can identify SIB 1 at the identified at least one frequency based on the second RAT. For example, after and / or simultaneously with performing a measurement at a frequency identified based on the MO, electronic device 101 can identify (e.g., decode) SIB 1 at the corresponding frequency; however, the electronic device can also be configured to identify SIB 1 while suppressing the performance of the measurement, depending on the implementation. SIB 1 may or may not include the Tracking Area Code (TAC) IE. The presence of the TAC field can indicate that the cell at least partially supports SA operation. The absence of the TAC field can indicate that the corresponding cell only supports EN-DC functionality.

[0113] According to various embodiments, in operation 907, electronic device 101 can determine the presence of a TAC corresponding to at least one frequency. For example, the electronic device can receive an RRC reconfiguration message as shown in Table 2. As described with respect to Table 2, the RRC reconfiguration message according to the examples in Table 2 may include ARFCNs “636654” and “627264” as frequencies to be measured. Electronic device 101 can identify a first SIB 1 at a first frequency corresponding to ARFCN “636654”, and can identify a second SIB 1 at a second frequency corresponding to ARFCN “627264”. Table 4 shows examples of SIB 1.

[0114] Table 4

[0115]

[0116] It can be identified that TAC "75bd0a" exists in the first SIB 1, while TAC does not exist in the second SIB 1. This may mean that the cell corresponding to ARFCN "636654" at least supports SA mode, while the cell corresponding to ARFCN "627264" only supports EN-DC.

[0117] According to various embodiments, when a TAC corresponding to at least one frequency is present (operation 907 "Yes"), in operation 909, electronic device 101 can perform a measurement of at least one first frequency where the TAC is present. When a TAC corresponding to at least one frequency is not present (operation 907 "No"), in operation 911, electronic device 101 can suppress the execution of a measurement of at least one second frequency where the TAC is not present. In the embodiment of SIB 1 in Table 4, electronic device 101 can perform a measurement at the frequency corresponding to ARFCN "636654" and can suppress the execution of a measurement at the frequency corresponding to ARFCN "627264".

[0118] Figure 10 This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0119] According to various embodiments, in operation 1001, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can perform a measurement of at least one first frequency that meets a condition. For example, electronic device 101 can identify that the at least one first frequency meets the condition associated with SA based on SIB 24 of a first RAT, based on pre-stored information, and / or based on SIB1 of a second RAT. In operation 1003, electronic device 101 can identify that the measurement result meets a reporting condition (e.g., B1 event). In operation 1005, based on the satisfaction of the reporting condition, electronic device 101 can execute a measurement report.

[0120] According to various embodiments, in operation 1007, electronic device 101 can receive an RRC reconfiguration message related to SCG addition from the network. For example, even if conditions associated with SA are met, the network can send an RRC reconfiguration message to electronic device 101 to perform SCG addition instead of handover. In this case, based on the electronic device being in a DC-limited state, electronic device 101 can suppress the execution of SCG addition. In operation 1009, electronic device 101 can send an SCG fault information message to the network. For example, electronic device 101 can send an SCG fault information message including the configuration "synchReconfigFailureSCG" as the cause of the SCG fault, and there is no limitation on the cause of the SCG fault. Although not shown, electronic device 101 can manage the frequency for the point where SA is disabled at the frequency corresponding to the SCG fault information message, and can also be configured not to perform measurements on the corresponding frequency thereafter.

[0121] Figure 11 This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0122] According to various embodiments, in operation 1101, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can perform a measurement of at least one first frequency that meets a condition. For example, electronic device 101 can identify that the at least one first frequency meets a condition associated with SA based on SIB 24 of a first RAT, based on pre-stored information, and / or based on SIB 1 of a second RAT. In operation 1103, electronic device 101 can identify that the measurement result meets a reporting condition (e.g., B1 event). In operation 1105, based on the satisfaction of the reporting condition, electronic device 101 can execute a measurement report.

[0123] According to various embodiments, in operation 1107, electronic device 101 can receive a handover command from the network. In operation 1109, electronic device 101 can perform a handover process based on the receipt of the handover command. For example, electronic device 101 can confirm a handover to the (R)AN (e.g., NG-RAN) corresponding to the second RAT based on the receipt of the handover command. Electronic device 101 can move from the (R)AN (e.g., E-UTRAN) corresponding to the first RAT (e.g., E-UTRA) and synchronize with the target (R)AN (e.g., NG-RAN). The (R)AN (e.g., NG-RAN) corresponding to the second RAT can notify electronic device 101 that it has handed over to the (R)AN (e.g., NG-RAN) to the core network (e.g., AMF) corresponding to the second RAT. The core network corresponding to the second RAT can notify the handover by sending a forward relocation completion notification message to the core network (e.g., MME) corresponding to the first RAT. Electronic device 101 can also perform a registration process from a system corresponding to the first RAT (e.g., EPS) to a system corresponding to the second RAT (e.g., 5GS). The handover process may follow, for example, 3GPP TS 23.502 or 3GPP TS 24.502, but is not limited thereto. Electronic device 101 can perform communication based on the second RAT after registering in the system of the second RAT via SA mode. Therefore, under DC-limited conditions, electronic device 101 can perform inter-RAT handover while preventing and / or mitigating DC.

[0124] Figure 12 This is a flowchart illustrating a method of operating an electronic device according to various embodiments. Figure 12In the embodiments described, the case where the first RAT is E-UTRA and the second RAT is NR is considered. However, those skilled in the art will understand that the embodiments described are also applicable to the case where the first RAT is NR and the second RAT is E-UTRA.

[0125] According to various embodiments, in operation 1201, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive SIB 24 from an LTE cell and store NR neighboring cell frequencies. For example, SIB 24 may include NR neighboring cell frequencies supporting SA mode. In operation 1203, electronic device 101 may enter DC-restricted mode. In operation 1205, electronic device 101 may receive an RRC reconfiguration message including MO. In operation 1207, electronic device 101 may determine, based on a database (DB), whether an NR frequency identified based on MO is determined to be NSA-enabled. Those skilled in the art will understand that whether SA is disabled can be alternatively and / or additionally determined as whether NSA is enabled. For example, whether SA is enabled and / or NSA is enabled for each frequency may be stored in the database. If it is determined that the NR frequency identified based on MO is NSA enabled (operation 1207 "Yes"), then in operation 1209, electronic device 101 can limit the measurement. Therefore, in operation 1211, electronic device 101 can maintain the connection to the LTE cell (or registration in EPS (or EPC)).

[0126] If it is determined that the NR frequency identified based on the MO is NAS disabled (operation 1207 "No"), then in operation 1213, the electronic device 101 can determine whether the NR frequency identified based on the MO is included in the neighboring cell frequencies included in SIB 24. The inclusion of the NR frequency identified based on the MO in the neighboring cell frequencies included in SIB 24 may mean that the NR frequency identified based on the MO supports SA mode. If the NR frequency identified based on the MO is included in the neighboring cell frequencies included in SIB 24 (operation 1213 "Yes"), then in operation 1215, the electronic device 101 can perform a measurement at the corresponding frequency. In operation 1217, the electronic device 101 can perform a measurement report based on the measurement result meeting reporting conditions (e.g., B1 event). If the NR frequency identified based on the MO is not included in the neighboring cell frequencies included in SIB 24 (operation 1213 "No"), then in operation 1219, the electronic device 101 can identify the SIB (e.g., SIB 1) at the NR frequency. In operation 1221, electronic device 101 can determine whether the cell corresponding to the NR frequency is a cell that supports SA mode based on the identified SIB (e.g., SIB 1). For example, electronic device 101 can determine whether the cell corresponding to the NR frequency is a cell that supports SA mode based on the presence of a TAC in the identified SIB 1. If it is determined that the cell corresponding to the NR frequency is a cell that supports SA mode (operation 1221 "Yes"), then in operation 1215, electronic device 101 can perform measurements at the NR frequency. If it is not determined that the cell corresponding to the NR frequency is a cell that supports SA mode (operation 1221 "No"), then in operation 1233, electronic device 101 can maintain the connection to the LTE cell.

[0127] According to various embodiments, electronic device 101 can execute a measurement report in operation 1217, and then in operation 1223, identify whether a handover command has been received from the network. As described above, when MR is executed based on the satisfaction of the conditions of the B1 event, the network can provide a handover command to electronic device 101, but in some cases, the network can also provide electronic device 101 with an RRC reconfiguration message related to SCG addition. If a handover command is received (operation 1223 "Yes"), then in operation 1225, electronic device 101 can execute the handover procedure. If no handover command is received (operation 1223 "No"), then in operation 1227, electronic device 101 can also receive an RRC reconfiguration message related to SCG addition. In operation 1229, based on electronic device 101 being in a DC-limited state, the electronic device can suppress the execution of SCG addition and send SCG fault information to the network. There are no restrictions on the cause of the SCG fault in the SCG fault information. In operation 1231, electronic device 101 can store the corresponding NR frequency in the database. For example, electronic device 101 can store the corresponding NR frequency as a frequency that enables NSA and / or disables SA. In operation 1233, electronic device 101 can maintain a connection to the LTE cell.

[0128] Figure 13 This is a flowchart illustrating a method of operating an electronic device according to various embodiments. Figure 13 In the embodiments described, the case where the first RAT is E-UTRA and the second RAT is NR is considered. However, those skilled in the art will understand that the embodiments described are also applicable to the case where the first RAT is NR and the second RAT is E-UTRA. Figure 12 In one embodiment, electronic device 101 receives SIB 24 based on the first RAT, but in Figure 13 In one embodiment, the electronic device 101 may not receive SIB24.

[0129] According to various embodiments, in operation 1301, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) may not receive SIB 24 from the LTE cell. Operation 1301 is simply given to describe electronic device 101 not receiving SIB 24, and electronic device 101 may be configured not to perform a separate operation to not receive SIB 24. In operation 1303, electronic device 101 may enter a DC-restricted mode. In operation 1305, electronic device 101 may receive an RRC reconfiguration message including the MO. In operation 1307, electronic device 101 may determine, based on a database (DB), whether an NR frequency identified based on the MO is determined to be NSA-enabled. For example, whether SA is enabled and / or NSA is enabled for each frequency may be stored in the database. If it is determined that the NR frequency based on MO identification is NSA enabled (operation 1307 "Yes"), then in operation 1309, electronic device 101 can limit the measurement. Therefore, in operation 1311, electronic device 101 can maintain the connection to the LTE cell (or registration in EPS (or EPC)).

[0130] If it is determined that the NR frequency identified based on MO is NSA disabled (operation 1307 "No"), then in operation 1313, electronic device 101 can identify an SIB (such as SIB 1) under the NR frequency. In operation 1315, electronic device 101 can determine whether the cell corresponding to the NR frequency is a cell that supports SA mode based on the identified SIB (such as SIB 1). For example, electronic device 101 can determine whether the cell corresponding to the NR frequency is a cell that supports SA mode based on the presence of a TAC in the identified SIB 1. If it is determined that the cell corresponding to the NR frequency is a cell that supports SA mode (operation 1315 "Yes"), then in operation 1317, electronic device 101 can perform measurements under the NR frequency. If it is determined that the cell corresponding to the NR frequency is not a cell that supports SA mode (operation 1315 "No"), then in operation 1331, electronic device 101 can maintain the connection to the LTE cell.

[0131] According to various embodiments, based on the fulfillment of reporting conditions (such as event B1), electronic device 101 can perform a measurement report in operation 1319, and then in operation 1321, identify whether a handover command has been received from the network. As described above, in the case of performing MR based on the fulfillment of the conditions of event B1, the network can provide a handover command to electronic device 101, but in some cases, the network can also provide electronic device 101 with an RRC reconfiguration message related to SCG addition. If a handover command is received (operation 1321 "Yes"), then in operation 1323, electronic device 101 can perform a handover procedure. If no handover command is received (operation 1321 "No"), then in operation 1325, electronic device 101 can also receive an RRC reconfiguration message related to SCG addition. In operation 1327, based on electronic device 101 being in a DC-limited state, the electronic device can suppress the execution of SCG addition and send SCG fault information to the network. There are no restrictions on the cause of the SCG fault in the SCG fault information. In operation 1329, electronic device 101 can store the corresponding NR frequency in the database. For example, electronic device 101 can store the corresponding NR frequency as a frequency that enables NSA and / or disables SA. In operation 1331, electronic device 101 can maintain a connection to the LTE cell.

[0132] Figure 14 This is a flowchart illustrating a method of operating an electronic device according to various embodiments.

[0133] According to various embodiments, in operation 1401, electronic device 101 (e.g., at least one of processor 120, first communication processor 212, second communication processor 214, or integrated communication processor 260) can receive an RRC reconfiguration message including MO based on a first RAT. In operation 1403, electronic device 101 can identify that DC is limited. In operation 1405, electronic device 101 can identify at least one frequency based on a second RAT based on MO. In operation 1407, electronic device 101 can perform a measurement on the identified at least one frequency. For example, in Figure 4 In one embodiment, the electronic device 101 performs measurements on frequencies that meet the conditions associated with the SA mode and suppresses measurements on frequencies that do not meet the conditions associated with the SA mode. Figure 14 The electronic device 101 of the embodiment can be configured to perform measurements on all frequencies based on MO identification. In operation 1409, the electronic device 101 can execute a measurement report based on the fulfillment of reporting conditions.

[0134] According to various embodiments, in operation 1411, electronic device 101 can identify whether a handover command has been received in response to a measurement report. If a handover command is received (operation 1411 "Yes"), then in operation 1413, electronic device 101 can perform a handover procedure. If no handover command is received (operation 1413 "No"), then in operation 1415, electronic device 101 can receive, for example, an RRC reconfiguration message related to SCG addition. Based on electronic device 101 being in a DC-limited state, the electronic device can suppress the execution of SCG addition and send an SCG fault information message to the network in operation 1417. Therefore, in a DC-limited state, electronic device 101 can perform inter-RAT handover while suppressing the execution of SCG addition.
