Description

[0001] This application is a divisional application of the application filed on February 19, 2019, with application number 201980014696.4, entitled "Electronic device and method for performing antenna tuning". Technical Field

[0002] This disclosure relates to electronic devices and methods for performing antenna tuning to improve the quality of voice services. Background Technology

[0003] With the development of wireless communication systems, voice call services have been provided over networks. For example, even in LTE, a high-speed data communication packet network, Voice over Long-Term Evolution (VoLTE) can provide voice call services in a manner similar to existing circuit-switched networks. In VoLTE, telecom companies can guarantee quality in the same way as mVoIP calls, and can also provide higher connection speeds and significantly improved call quality compared to existing circuit-switched call types. Summary of the Invention

[0004] Technical issues

[0005] LTE / 5G communication, as an environment for serving VoLTE and VoIP, is a communication standard developed for data communication and can use antenna tuning values ​​targeted at data-based throughput. Therefore, when generating large amounts of data in addition to voice packets while using voice services, quality degradation such as call distortion or silence may occur.

[0006] For example, when Carrier Aggregation (CA) is active, a user terminal can use antenna tuner values ​​that allocate radio resources to P and S cells by controlling the electric fields of the primary cell (P cell) and secondary cell (S cell) to converge them to an average value. In other words, because the user terminal uses antenna tuning values ​​optimized for maximum throughput in data-based laboratory performance testing, using VoLTE service provided by P cell may not offer optimal performance.

[0007] According to various embodiments, this disclosure may provide an electronic device and method that, when a voice service begins while a CA is activated, prioritizes the quality of the voice service by tuning an antenna to at least one transmission frequency tuned to the P cell, even while the CA is activated.

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. According to an embodiment, display device 160 may include touch circuitry adapted to detect touch or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of the force caused by touch.

[0039] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input device 150, or output sound via the sound output device 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.

[0040] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

[0041] Interface 177 may support one or more specific protocols used to enable electronic device 101 to connect directly (e.g., wired) or wirelessly to external electronic devices (e.g., electronic device 102).

[0047] 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 supporting 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). A corresponding one of these communication modules can communicate via a first network 198 (e.g., a short-range communication network, such as Bluetooth). TM The wireless communication module 192 communicates with external electronic devices via a Wi-Fi Direct or Infrared Data Association (IrDA) network or a second network 199 (e.g., a long-range communication network such as a cellular 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.

[0049] Figure 2This is a block diagram illustrating an example electronic device according to various embodiments. According to an embodiment, electronic device 101 may include a MODEM 201, a radio frequency (RF) IC 203 including a Tx module (e.g., including transmission circuitry) 205 and an Rx module (e.g., including receiving circuitry) 207, a pulse amplitude modulation (PAM) (e.g., including amplifier circuitry) 209, and a plurality of antennas 211-1 to 211-n. Figure 2 The MODEM201 and RFIC 203 can be Figure 1 The components included in the communication module 190, and Figure 2 The RAM 209 and multiple antennas 211-1 to 211-m can be Figure 1 The antenna module 197 includes the following components.

[0050] refer to Figure 2 MODEM 201 can be connected to Tx module 205 and Rx module 207 of RFIC 203.

Figure 2 The diagram shows Tx module 205 connected to an antenna 211-1, but this disclosure is not limited thereto.

[0051] Figure 3A This is a flowchart illustrating example operations of an electronic device using an antenna tuning mode according to various embodiments.

[0052] According to various embodiments, in operation 301, electronic device 101 (e.g., processor 120) may be configured for carrier aggregation of wireless communication. For example, the configuration of carrier aggregation of wireless communication may refer to, for example, electronic device 101 receiving a cell different from the operating cell from a base station (BS).

[0053] According to various embodiments, in operation 303, electronic device 101 can control the communication circuit to use a first antenna tuning mode belonging to a first group. For example, the antenna tuning modes belonging to the first group can be modes that can be used both when a voice call event occurs (or during a voice call event) and when a voice call event is not performed. For example, electronic device 101 can use antenna tuning modes corresponding to one or more predetermined states of electronic device 101 (e.g., but not limited to, basic state, USB connected state, and flip-cover-mounted state) in both the state of performing a voice call event and the state of not performing a voice call event. The first group can be, for example, but not limited to, a group of antenna tuning modes corresponding to free space (basic state), USB (USB connected state), and flip (flip-cover-mounted state).

[0054] According to various embodiments, in operation 305, electronic device 101 can identify (determine) whether carrier aggregation for wireless communication is activated. Activation of carrier aggregation for wireless communication may refer to, for example, electronic device 101 performing communication using two or more different carriers. When carrier aggregation is not activated (no), in operation 303, electronic device 101 can maintain a first antenna tuning mode.

[0055] According to various embodiments, when carrier aggregation is activated, in operation 307, electronic device 101 can control the communication circuit to use a second antenna tuning mode belonging to the second group. Examples of antenna tuning modes belonging to the second group may include, for example, an antenna tuning mode corresponding to the activation of carrier aggregation. According to embodiments, antenna tuning modes belonging to the second group may include, for example, modes not used while performing a voice call event. For example, electronic device 101 may use the antenna tuning mode corresponding to CA activation and 4Rx diversity (4RxD) without performing a voice call event, but may not use the antenna tuning mode corresponding to CA activation and 4RxD while performing a voice call event. The second group may be a set of antenna tuning modes corresponding to CA activation and 4RxD. In this disclosure, 4RxD may refer to, for example, four antennas configured for receiving signals (including the RFICRx path).

[0056] According to various embodiments, electronic device 101 can identify (determine) whether a voice call event is being executed in operation 309. For example, a voice call event may include a voice service based on Long Term Evolution Voice Bearer (VoLTE). For example, a voice call event may be generated when electronic device 101 receives a call from and / or transmits a call to an external electronic device. When no voice call event is being executed, electronic device 101 may return to operation 307 or may remain in second-line tuning mode.

[0057] According to various embodiments, when a voice call event is being performed, in operation 311, the electronic device 101 can control the communication circuit to use a third antenna tuning mode belonging to the first group. When carrier aggregation is activated and a voice call event is being performed, the electronic device 101 can control the communication circuit to use a third antenna tuning mode belonging to the first group. While a voice call event is being performed under the control of the electronic device 101, the communication circuit can use a third antenna tuning mode belonging to the first group instead of a second antenna tuning mode belonging to the second group.

[0058] Figure 3B This diagram illustrates example operations of using antenna tuning modes for voice services according to various embodiments. Configuration A may refer to, for example, an antenna tuning mode corresponding to one or more predetermined states of the electronic device 101 when it is used while the device is served by one cell (e.g., basic state, USB connected state, and flip-phone state). Configuration B may refer to, for example, an antenna tuning mode corresponding to one or more predetermined states of the electronic device 101 when it is served by at least two cells (e.g., when carrier aggregation is activated) (e.g., whether CA is activated and whether 4×4 MIMO is applied). Configuration C may refer to, for example, an antenna tuning mode corresponding to one or more predetermined states of the electronic device 101 when it is used while the device is served by at least two cells (e.g., carrier aggregation is activated) and a voice call event is being performed (e.g., basic state, USB connected state, and flip-phone state). The antenna tuning modes corresponding to one or more predetermined states of the electronic device 101 may be included, for example, in a lookup table stored in memory.

[0059] refer to Figure 3BElectronic device 101 can operate in configuration A327 when carrier aggregation is configured as indicated by reference numeral 321. For example, when electronic device 101 is served by a single cell, electronic device 101 can operate in configuration A327. When carrier aggregation is activated as indicated by reference numeral 323, electronic device 101 can operate in configuration B329. For example, when carrier aggregation is activated, in configuration B329, electronic device 101 can use an antenna tuning mode that converges the electric fields of the primary cell (P cell) and the secondary cell (S cell) to an average value for the data service performed in configuration B329. For example, operation performed in configuration B329 may refer to, for example, when carrier aggregation is activated, electronic device 101 tuning its antenna to allocate radio resources to P cell and S cell. According to an embodiment, when a voice call event begins, as indicated by reference numeral 325, electronic device 101 can operate in configuration C331. For example, when a voice call event begins, as indicated by reference numeral 325, with carrier aggregation activated, electronic device 101 can use a P-cell to perform the voice call event in configuration C331. When electronic device 101 operates in configuration B329, the antenna is tuned to allocate radio resources to both P-cell and S-cell, thus the quality of the voice call event using the P-cell can be disregarded. When a voice call event begins, as indicated by reference numeral 325, with carrier aggregation activated, electronic device 101 can operate in configuration C331 to tune the antenna for the quality of the voice call event using the P-cell. For example, operation in configuration C331 could mean, for example, that, with carrier aggregation activated, electronic device 101 tunes the antenna to obtain the optimal performance of the P-cell.

[0060] Figure 4A This is a flowchart illustrating example operations of an electronic device using an antenna tuning mode according to various embodiments.

[0061] According to various embodiments, in operation 401, electronic device 101 (e.g., processor 120) can access a network. At this time, electronic device 101 can operate within a single cell.

[0062] According to various embodiments, in operation 403, electronic device 101 may tune an antenna for a P-cell. For example, a P-cell may be a cell in which electronic device 101 operates in operation 401. For example, tuning an antenna for a P-cell by electronic device 101 may refer to, for example, tuning the antenna based on the transmission frequency of the P-cell in order to optimize and / or improve transmission performance.

[0063] According to various embodiments, in operation 405, electronic device 101 may be configured with carrier aggregation. The configuration of carrier aggregation may refer to, for example, reception from an S cell of the BS.

[0064] According to various embodiments, in operation 407, electronic device 101 can activate carrier aggregation. Activation of carrier aggregation can refer to, for example, using P-cells and S-cells to operate communications.

[0065] According to various embodiments, in operation 409, electronic device 101 can target an active carrier aggregation tuning antenna. For example, electronic device 101 can instruct the active carrier aggregation tuning antenna to tune the antenna, for example, based on all frequencies used when cells P and S do not use consecutive frequencies in the same frequency band but use frequencies in different frequency bands.

[0066] According to various embodiments, in operation 411, electronic device 101 can initiate a voice call event. For example, the voice call event can be based on Long Term Evolution Voice Bearer (VoLTE). For example, a P cell can be used to perform the voice call event while carrier aggregation is activated.

[0067] According to various embodiments, in operation 413, electronic device 101 can change the antenna tuning for cell P. For example, electronic device 101 can tune the state of an antenna tuned for the electric fields of cells P and S to a state where the antenna is tuned for cell P. By tuning the antenna for cell P, the quality of voice service using cell P can be improved.

[0068] According to various embodiments, in operation 415, electronic device 101 can terminate the voice call event. For example, the voice call event can be terminated when the call is terminated by the user and / or by an external electronic device.

[0069] According to various embodiments, in operation 417, electronic device 101 can identify (determine) whether carrier aggregation is activated.

[0070] According to various embodiments, when carrier aggregation is activated, in operation 419, electronic device 101 can tune the antenna for activating carrier aggregation. For example, electronic device 101 can tune the antenna to allocate radio resources to P-cells and S-cells.

[0071] According to various embodiments, when carrier aggregation is not activated, in operation 421, electronic device 101 can maintain antenna tuning for the P-cell. In the inactive state of carrier aggregation, electronic device 101 can operate in a single cell (i.e., P-cell) such that electronic device 101 can maintain the antenna tuning for the P-cell as described in operation 413.

[0072] Figure 4B This is a diagram illustrating example operation of using an antenna tuning mode for a voice call event according to various embodiments. Figure 4BConfiguration A, Configuration B, and Configuration C can refer to, for example, Figure 4C Configurations A, B, and C, and can be compared with the reference. Figure 3B The descriptions are the same or similar. (Reference) Figure 4B When carrier aggregation is configured as indicated by reference numeral 451, electronic device 101 can operate in configuration A463. When carrier aggregation is activated as indicated by reference numeral 453, electronic device 101 can operate in configuration B465. For example, when carrier aggregation is activated, electronic device 101 can operate in configuration B465 to tune the antenna to allocate radio resources to P-cells and S-cells. When a voice call event begins as indicated by reference numeral 455, electronic device 101 can operate in configuration C467 simultaneously with carrier aggregation activation. For example, when a voice call event begins as indicated by reference numeral 455, electronic device 101 can operate in configuration C467 simultaneously with carrier aggregation activation to tune the antenna for the performance of the P-cell for the voice call event quality. When a voice call event ends (e.g., is terminated) as indicated by reference numeral 457, electronic device 101 can again operate in configuration B469. When carrier aggregation is disabled as indicated by reference numeral 459 in the attached figure, electronic device 101 can be operated again in configuration A471. Figure 4B As shown, when a voice call event begins as indicated by reference numeral 455, while electronic device 101 operates in configuration B465 according to carrier aggregation activation 453, electronic device 101 can operate in configuration C467 instead of configuration B441. For example, according to various embodiments, when a voice call event begins simultaneously with carrier aggregation activation, electronic device 101 can improve the quality of the voice call event by using a performance-tuned antenna for the P cell.

[0073] Figure 4C This is a diagram illustrating example antenna patterns according to various embodiments. For example, Figure 4CThe table shown may be a lookup table stored in electronic device 101 for changing antenna configuration. For example, the lookup table may include antenna tuning modes for predetermined states, such as, but not limited to, free space (basic state), AP event mode (USB connection state or headphone jack connection state), CA activation (CA activation state), 4RXD (4RxD application state), 4×4MIMO (4×4MIMO application state), etc. For example, electronic device 101 may tune the antenna based on multiple events such as free space (basic state) and AP event mode (USB connection state or headphone jack connection state) or based on the priority of multiple modes. Meanwhile, in this disclosure, coarse tuning may refer to, for example, antenna tuning corresponding to multiple events. For example, coarse tuning may refer to, for example, initially tuning the antenna with a tuning type corresponding to at least one of the multiple events.

[0074] When carrier aggregation is disabled (or electronic device 101 is served by a single cell), electronic device 101 can operate in configuration A. For example, configuration A may refer to electronic device 101 tuning its antenna based on the frequency of cell P according to events in free space (basic state) and AP event mode (USB connection state or headphone jack connection state). Electronic device 101 can configure a final operating mode based on the priority of available operations among multiple events. According to an embodiment, when carrier aggregation is activated, electronic device 101 can operate in configuration B. For example, configuration B may refer to electronic device 101 tuning its antenna according to a CA activation event using a stored lookup table. According to an embodiment, when a voice call event is performed while carrier aggregation is activated, electronic device 101 can operate in configuration C. For example, configuration C may refer to electronic device 101 tuning its antenna based on the transmission frequency of cell P, instead of using the antenna tuning mode used when carrier aggregation is activated. Configuration C may include, for example, but not limited to, antenna tuning values ​​for optimizing and / or improving the transmission performance of the P cell. The quality of voice call events using the P cell can be improved by preventing and / or reducing the use of CA-activated antenna modes during voice call events (e.g., by tuning the antenna based on the transmission frequency of the P cell).

[0075] Figure 5A This is a block diagram illustrating example electronic devices according to various embodiments. According to the embodiments, besides… Figure 2 In addition to the components of the electronic device 101, Figure 5AThe electronic device 101 may also include a coupler (e.g., including coupling circuitry) 513 and a feedback receiver (FBRX) module (e.g., including feedback receiver circuitry) 507. Since the MODEM 501, Tx module 505, Rx module 509, and pulse amplitude modulation (PAM) 511 are related to the reference... Figure 2 The descriptions are the same or similar, so they need not be repeated here.

[0076] According to an embodiment, electronic device 101 can use FBRX module 507 to receive reflected waves of signals transmitted from Tx module 505 via coupler 513. Upon receiving the reflected wave of the transmitted signal, MODEM 501 can analyze the impedance. According to an embodiment, electronic device 101 can tune the antenna to configure optimal and / or improved impedance values ​​based on the analyzed impedance. In this disclosure, fine-tuning can refer to, for example, finer tuning of the coarse-tuning value to configure optimal and / or improved impedance values ​​based on the reflected wave of the transmitted signal.

[0077] Figure 5B This is a flowchart illustrating example methods of fine-tuning an antenna in an antenna tuning mode by an electronic device according to various embodiments. Figure 5B In this context, it is assumed that carrier aggregation is activated, so electronic device 101 uses P-cells and S-cells to perform communication.

[0078] According to various embodiments, in operation 531, electronic device 101 (e.g., processor 120) can identify (determine) whether a voice call event is being performed.

[0079] According to various embodiments, when no voice call event is being performed (No), in operation 533, electronic device 101 may update the antenna tuning mode for a data service (e.g., a web browser). For example, electronic device 101 may use at least one frequency for carrier aggregation to tune the antenna.

[0080] According to various embodiments, when a voice call event is being performed (Yes), in operation 535, electronic device 101 can update (or change) the antenna tuning mode for the voice call event. For example, electronic device 101 can tune the antenna using at least one transmission frequency for a P-cell. Since electronic device 101 primarily uses a P-cell to perform voice call events, the quality of the voice call event can be improved by tuning the antenna using the transmission frequency of the P-cell.

[0081] According to various embodiments, in operation 537, electronic device 101 can identify (determine) whether the transmission power is higher than a threshold. When the received electric field strength corresponds to a medium / weak electric field, the transmission power of electronic device 101 can be increased, such that electronic device 101 can identify (determine) whether the transmission power is higher than the threshold and identify (determine) whether electronic device 101 is located in a medium / weak electric field region. When the transmission power is equal to or lower than the threshold (e.g., when electronic device 101 is located in a strong electric field) (No), electronic device 101 can return to operation 531, and in operation 531 identify (determine) whether a voice call event is being performed.

[0082] When the transmitted power exceeds a threshold (e.g., when electronic device 101 is in a medium / weak electric field region), in operation 539, electronic device 101 can perform monitoring for fine-tuning. For example, when the antenna's input impedance changes due to being held in the hand (held within a segment) in a medium / weak electric field region, the antenna's transmission efficiency may change. To identify (determine) the antenna's transmission efficiency, electronic device 101 can receive the reflected wave of the transmitted signal via a coupler and analyze the impedance.

[0083] According to various embodiments, in operation 541, the electronic device 101 can update the antenna tuning mode based on monitoring results. For example, the electronic device 101 can tune the antenna to configure the optimal value of the analyzed impedance based on the reflected wave of the transmitted signal.

[0084] [Table 1]

[0085]

[0086] [Table 1] above illustrates an example of tuning an antenna while performing a voice call event. For example, in operation 535, electronic device 101 can tune the antenna for multiple events A, B, and C (e.g., USB and headphone jack). When it is identified (determined) that fine-tuning is needed, electronic device 101 can tune the antenna to at least some of the values ​​of A1, A2, A3, B1, B2, B3, C1, C2, and C3 to configure the optimal and / or improved values ​​of the analyzed impedance based on the reflected wave of the transmitted signal. For example, when a medium / weak electric field region is identified, electronic device 101 can optimize the antenna configuration for the voice call event by performing fine-tuning. According to various embodiments, the antenna tuning (i.e., coarse tuning) for multiple events A, B, and C can be changed based on the result of fine-tuning. For example, when the tuning value of A3 is changed to B1 by fine-tuning, electronic device 101 can tune the antenna for event B.

[0087] Figure 6A This is a flowchart illustrating example operations of an electronic device using an antenna tuning mode according to various embodiments.

[0088] According to various embodiments, in operation 601, electronic device 101 (e.g., processor 120) may apply advanced receiver diversity (ARD) (e.g., 4RxD). For example, electronic device 101 may tune antennas to receive data via four antennas.

[0089] According to various embodiments, in operation 603, electronic device 101 can identify (determine) whether a voice call event is being performed. When no voice call event is being performed, electronic device 101 can apply ARD in operation 601. For example, electronic device 101 can maintain an antenna tuning mode for receiving data via four antennas.

[0090] According to various embodiments, when a voice call event is being performed, in operation 605, the electronic device 101 can change the antenna tuning mode used for the P-cell. For example, since the voice call event is primarily performed using the P-cell, the performance of the voice call event may degrade if it is performed using an antenna tuned to receive data through four antennas. When a voice call event is being performed, the electronic device 101 can improve the performance of the voice call event by tuning the antenna to the transmission frequency based on the P-cell.

[0091] According to various embodiments, in operation 607, electronic device 101 can terminate the voice call event.

[0092] According to various embodiments, in operation 609, electronic device 101 can identify (determine) whether ARD is available. When ARD is unavailable, electronic device 101 can change the antenna tuning mode based on an event corresponding to the current state among various events. For example, when carrier aggregation is activated, electronic device 101 can tune the antenna based on at least one frequency used for carrier aggregation. Furthermore, when electronic device 101 is operating in a cell, electronic device 101 can tune the antenna based on the transmission frequency of cell P.

[0093] According to various embodiments, when ARD is available, in operation 613, electronic device 101 can change the antenna tuning mode to an antenna tuning mode for ARD. For example, when electronic device 101 can use ARD and therefore performs a voice call event while maintaining the antenna tuning mode for ARD, electronic device 101 can use the antenna tuning mode for P cell instead of the antenna tuning mode for ARD while performing the voice call event, thereby improving the quality of the voice call event performed using P cell.

[0094] Figure 6BThis is a diagram illustrating example operation using an antenna tuning mode for voice services according to various embodiments. (Reference) Figure 6B When electronic device 101, operating in configuration A639, starts 4RxD (or MIMO mode) as indicated by reference numeral 631, electronic device 101 can operate in configuration B641. For example, 4RxD can be a mode for receiving data through four antennas. For example, electronic device 101 can tune the antennas to receive data through four antennas. When electronic device 101 starts a voice call event while operating in configuration B641 as indicated by reference numeral 633, electronic device 101 can operate in configuration C643. For example, when a voice call event starts while electronic device 101 is operating in 4RxD mode as indicated by reference numeral 633, electronic device 101 can operate in configuration C643 to tune the antennas for the performance of the P cell for the voice call event quality. When the voice call event ends (e.g., is terminated) as indicated by reference numeral 635, electronic device 101 can again operate in configuration B645. According to an embodiment, when 4RxD (or MIMO mode) ends (e.g., is terminated), the electronic device 101 can operate again in configuration A647. Figure 6B As shown, when a voice call event begins simultaneously with electronic device 101 operating in configuration B641 according to 4RxD, as indicated by reference numeral 633, electronic device 101 can operate in configuration 643 instead of configuration B641. According to various embodiments, when a voice call event begins during 4RxD mode, electronic device 101 can improve the quality of the voice call event by tuning the antenna for the performance of the P-cell.

[0095] Figure 7 This is a flowchart illustrating example operation of an electronic device using an antenna tuning mode according to various embodiments. In this disclosure, for example, the first protocol stack and the second protocol stack can be a first Subscriber Identification Module (SIM) and a second SIM, respectively. For example, the first protocol stack and the second protocol stack can be stacks for fourth-generation (4G) mobile communication and stacks for fifth-generation (5G) mobile communication, respectively. The first protocol stack and the second protocol stack can be stacks for using different hardware included within the electronic device 101, and there is no limitation on the type of protocol stack. The first protocol stack and the second protocol stack can share an antenna.

[0096] According to various embodiments, in operation 701, electronic device 101 (e.g., processor 120) can use a first protocol stack to perform communication.

[0097] According to various embodiments, in operation 703, electronic device 101 can identify (determine) whether a voice call event has been generated in the first protocol stack. When it is identified (determined) that no voice call event has been generated in the first protocol stack, electronic device 101 can return to operation 701 and perform communication using the first protocol stack.

[0098] When a voice call event is identified (determined) in the first protocol stack, in operation 705, electronic device 101 can use a first antenna tuning mode corresponding to the voice call event. For example, electronic device 101 can tune the antenna based on at least one transmission frequency of cell P according to the voice call event.

[0099] According to various embodiments, while a voice call event is being executed, electronic device 101 can perform data services in a second protocol stack during operation 707. Electronic device 101 can request to change the antenna tuned according to the voice call event to an antenna tuning mode corresponding to the data service in the second protocol stack.

[0100] According to various embodiments, in operation 709, electronic device 101 can ignore a request to change the antenna tuning mode to a second antenna tuning mode corresponding to the data service event. For example, electronic device 101 can recognize (determine) that the voice call event has a higher priority than the data service, and even if a request is made to change the state of the antenna tuning according to the voice call event to the antenna tuning mode corresponding to the data service, it can ignore the request. For example, electronic device 101 can maintain the quality of the voice call event by tuning the antenna according to the voice call event while the voice call event is being executed in the first protocol stack, and by ignoring the request to change to another mode.

[0101] Figure 8A This is a diagram illustrating an example operation using an antenna tuning mode for voice services according to a comparative embodiment. (Reference) Figure 8A A voice call event can be initiated in the first protocol stack 803. When a voice call event is initiated in the first protocol stack 803, the first RF driver 805 of the first protocol stack 803 can request the antenna 807 to change to an antenna tuning mode for the voice call mode. For example, the electronic device 101 can tune the antenna 807 according to the voice call event. The electronic device 101 can maintain the antenna tuning mode corresponding to the voice call event by pausing the activation of the second protocol stack 809 (and thereby pausing the activation of the second RF driver 811) while the voice call event is being executed in the first protocol stack.

[0102] Figure 8B This is a diagram illustrating example operation of using an antenna tuning mode for a voice call event according to various embodiments. (Reference) Figure 8B A voice call event can begin in the first protocol stack 803. When a voice call event begins in the first protocol stack 803, the first RF driver 805 of the first protocol stack 803 can request the antenna 807 to change to an antenna tuning mode for the voice call mode. For example, the electronic device 101 can tune the antenna 807 according to the voice call event. While the voice call event is being executed in the first protocol stack 803, data service can begin in the second protocol stack 809. The second RF driver 811 of the second protocol stack 809 can request the antenna 807 to change to an antenna tuning mode for data service. The electronic device 101 can ignore the request to change the antenna tuning mode from the second RF driver 811 of the second protocol stack 809 and connect to the second RF driver 811 of the second protocol stack 809 through an antenna tuning mode corresponding to the voice call event of the first protocol stack 803. Therefore, the electronic device 101 can maintain the antenna tuning mode for the voice call event. For example, electronic device 101 can execute a voice call event in a first protocol stack 803 and provide data services in a second protocol stack 809 by using an antenna tuning mode optimized and / or improved for the voice call event.

[0103] Figure 8C This is a flowchart illustrating example operations performed in a first protocol stack according to various embodiments. Figure 8D This is a flowchart illustrating example operations performed in a second protocol stack according to various embodiments. Electronic device 101 can operate in a first protocol stack and / or a second protocol stack.

[0106] According to various embodiments, in operation 855, electronic device 101 can change a voice call event to a Tx / Rx state based on the voice call event. For example, electronic device 101 can tune an antenna based on the voice call event.

[0107] According to various embodiments, in operation 857, the voice call event can be terminated in the first protocol stack.

[0108] refer to Figure 8D According to various embodiments, in operation 861, electronic device 101 can configure network data in a second protocol stack.

[0109] According to various embodiments, in operation 863, electronic device 101 can start data service in a second protocol stack.

[0110] According to various embodiments, in operation 865, electronic device 101 may not perform changes to the Tx / Rx state for data service. For example, electronic device 101 may perform data service in the second protocol stack while simultaneously performing voice call events in the first protocol stack (e.g., without changing the antenna tuning). Figure 8C (Operation 855). For example, electronic device 101 can identify (determine) that the priority of voice call service is higher than that of data service, and maintain the antenna tuning mode corresponding to the voice call event while executing the voice call event. Electronic device 101 can execute data service in a second protocol stack through the antenna tuned according to the voice call event.

[0111] According to various embodiments, in operation 867, the termination of a voice call event in the first protocol stack can be recognized.

[0112] According to various embodiments, in operation 869, electronic device 101 can execute changes to the Tx / Rx state for data services. For example, when a voice call event ends in the first protocol stack, electronic device 101 can tune its antenna according to the data service. Electronic device 101 can then perform data services in the second protocol stack using the antenna tuned according to the data service.

[0113] According to various embodiments, in operation 871, electronic device 101 can terminate data service. For example... Figure 8C and 8D As shown, while executing a voice call event in the first protocol stack, the electronic device 101 can maintain the antenna tuning mode corresponding to the voice call mode (i.e., the second protocol stack can remain unchanged in the antenna tuning mode) to prevent and / or reduce the degradation of the quality of the voice call event.
