Description

Method and device for simultaneously supporting DUDAL SIM operation {METHOD AND APPARATUS FOR SUPPORTING DUAL SIM OPERATION SIMULTANEOUSLY}

Various embodiments of the present invention disclose a method and an apparatus for simultaneously supporting a DUAL SIM operation.

With the development of digital technology, various types of electronic devices such as mobile communication terminals, personal digital assistants (PDAs), electronic notebooks, smart phones, tablet PCs (personal computers), and wearable devices are widely used. In order to support and increase functions of the electronic device, the hardware part and/or the software part of the electronic device are continuously improved.

Electronic devices, for example, provide the ability to write two phone numbers through two subscriber identification modules (SIMs). That is, the dual SIM electronic device can use two phone numbers and two network services with one electronic device. The dual SIM electronic device receives a selection of a SIM to be used from a user when a phone call or text is sent, and can send a phone or text message through a communication network associated with the selected SIM. Such a dual SIM electronic device may be classified into a dual SIM dual standby (DSDS) method and a dual SIM dual active (DSDA) method.

In the DSDS type electronic device, while one of the two shims is used, the other shim cannot be used. On the other hand, the DSDA-type electronic device may use the other shim even if one of the two shims is used. For example, in the DSDS method, while the first SIM is in use, the second SIM cannot receive or send texts as well as calls, and data communication cannot be performed.

In the DSDS type electronic device, since the first SIM and the second SIM share radio frequency (RF) resources, collisions related to the use of the first SIM and the second SIM may occur. When the first SIM and the second SIM are to be used at the same time, the electronic device may selectively control the RF resource to be used by the first SIM or the second SIM based on priority. For example, if the first SIM and the second SIM need to receive data in the same frequency band, while the first SIM receives data (or signals), the second SIM cannot receive data blackout (black out) can occur. Alternatively, the first SIM may temporarily stop receiving data in order to receive the data for the second SIM. Since the first SIM and the second SIM cannot simultaneously receive data, a TCP throughput or call performance of the electronic device may be degraded.

In order to solve such blackout, electronic devices are improving communication modules in hardware. For example, when the frequency bands used by the first SIM and the second SIM are different, the electronic device may simultaneously receive signals from the first SIM and the second SIM without conflict of use of RF resources. However, when the frequency bands used by the first and second shims are the same, the electronic device may not be able to simultaneously receive signals from the first and second shims. In order to simultaneously receive signals of the same frequency band in the first and second shims, four antennas may be required in the electronic device.

In various embodiments, at least two mixers are provided in an electronic device including a dual SIM, so that different signals of the same frequency band are separated through each mixer so that the first SIM and the second SIM are separated. It is possible to disclose a method and apparatus for enabling simultaneous reception of signals.

An electronic device according to various embodiments of the present disclosure includes a radio frequency integrated circuit (RFIC) including a first subscriber identification module, a second SIM, a first mixer, and a second mixer, and a memory; And a processor, wherein the processor receives a second signal for the second SIM while receiving the first signal for the first SIM, and the first signal and the second signal use the same frequency band. It is determined whether or not, and when the first signal and the second signal use the same frequency band, it may be set to activate a dual-sim simultaneous support function using the first mixer and the second mixer.

According to various embodiments of the present disclosure, a method of operating an electronic device including a dual SIM includes an operation of receiving a second signal for the second SIM while receiving a first signal for the first SIM, the first signal and Determining whether the second signal uses the same frequency band, and when the first signal and the second signal use the same frequency band, a first mixer and a second mixer included in the RFIC of the electronic device It may include an operation of activating a dual sim simultaneous support function using a mixer.

According to various embodiments, at least two mixers are provided in an electronic device including a dual SIM, so that different signals of the same frequency band are separated through each mixer so that the first SIM and the second SIM receive signals at the same time. You can do it.

According to various embodiments, when a level difference between a signal received in the same frequency band is less than or equal to a threshold, the dual sim simultaneous support function may be activated.

According to various embodiments, by adjusting the gain of the low-noise amplifier based on the difference in the level of the received signal, the first shim and the second shim may simultaneously receive signals.

However, when the frequency bands used by the first shim and the second shim are the same, collision may occur in the use of RF resources. In this case, the first SIM and the second SIM may not be able to simultaneously receive signals. Alternatively, in order to increase signal reception performance, the RFIC 230 may control the first SIM and the second SIM to simultaneously receive signals through the first antenna module 211 under the control of the communication processor 250. have. The reception performance of the first antenna module 211 may be better than that of the second antenna module 213.

May be included. The low noise amplifier 241 may amplify the RF signal acquired through the first antenna module 211. When the first SIM and the second SIM receive signals of the same frequency band, the RFIC 230 uses the first and second mixers 243 and 245 as signals for the first and second SIMs, respectively. Can be separated. For example, the first mixer 243 may convert the obtained RF signal into a signal for the first SIM. The second mixer 245 may convert the obtained RF signal into a signal for a second shim.

The communication processor 250 may control the first SIM and the second SIM to simultaneously receive signals when the frequency bands used by the first SIM and the second SIM are the same. For example, the communication processor 250 may control to obtain an RF signal from the first antenna module 211 and the second antenna module 213. The obtained RF signal may include a signal for a first SIM and a signal for the second SIM. The communication processor 250 separates the obtained RF signal into a signal for the first SIM through the first mixer 243 included in the RFIC 230, and separates the second mixer 245 included in the RFIC 230. It can be separated into a signal for the second shim through. The communication processor 250 may measure a level of a signal for a first shim separated from the first mixer 243 and measure a level of a signal for a second shim separated from the second mixer 245.

The communication processor 250 may activate a dual SIM simultaneous support function (or mode) based on the difference between the measured signal levels. Activating the dual SIM simultaneous support function may be controlling the first SIM and the second SIM to simultaneously receive signals.

The communication processor 250 may adjust the gain of the low noise amplifier 241 included in the RFIC 230 when the signal level difference is greater than or equal to the threshold. The communication processor 250 may activate a dual sim simultaneous support function by adjusting the gain of the low noise amplifier 241. Alternatively, the communication processor 250 may deactivate (terminate) a dual SIM simultaneous support function when the signal level difference exceeds a certain range (eg, a fourth range) from a threshold. Deactivating the simultaneous dual-sim support function may be controlling so that a signal can be received only through one of the first and second SIMs.

According to various embodiments, the communication processor 250 may support establishment of a communication channel of a band to be used for wireless communication and network communication through the established communication channel.

For example, when the first shim and the second shim use frequency signals of different bands, the communication processor 250 uses the first antenna module 211 and the second antenna module 213 as the first shim. If the third antenna module 215 and the fourth antenna module 217 set different reception paths as the second shim, but the first shim and the second shim use frequency signals of the same band, the second shim The deliberation receiving path may be changed to be the same as the first deliberation receiving route.

Referring to FIG. 3, an electronic device 101 according to various embodiments may include an RFFE 221, an RFIC 230, and a communication processor 250. The RFFE 221 may include a first low noise amplifier 350. The RFIC 230 may include a second low noise amplifier 241 and a down converter 360. The second low-noise amplifier 241 is only described as "second" to distinguish it from the first low-noise amplifier 350, and is the same as the low-noise amplifier 241 of FIGS. 2A and 2B. The down converter 360 is a mixer, and may include the first mixer 243 and the second mixer 245 of FIGS. 2A and 2B.

The first antenna module 211 of the electronic device 101 may receive an RF signal from the first base station 310 and the second base station 320. For example, the first base station 310 transmits the first signal 311 to the first shim of the electronic device 101, and the second base station 320 transmits the second shim to the second shim of the electronic device 101. The signal 321 can be transmitted. The first signal 311 and the second signal 321 may be signals having the same frequency band. The first antenna module 211 may acquire an RF signal including the first signal 311 and the second signal 321. The RF signal including the first signal 311 and the second signal 321 may be preprocessed through the RFFE 221. The RFFE 221 may amplify the RF signal through the first low noise amplifier 350. The RFIC 230 amplifies the RF signal output from the RFFE 221 through the second low noise amplifier 241, and converts the amplified RF signal through the down converter 360 to the first signal 311 and the second signal. Can be separated by 321.

The communication processor 250 may include a signal check module 371, a signal saturation check module 373, a gain calculation module 375, and a gain control module 377. The signal check module 371, the signal saturation check module 373, the gain calculation module 375, and the gain control module 377 are provided with a communication processor 250 (or a processor (e.g., FIG. It may be included in the processor 120 of 1 as a hardware module, or may be included as a software module.

The signal check module 371 may check a signal level (or magnitude) of each of the first signal 311 and the second signal 321. The first signal 311 and the second signal 321 are each received from a base station (for example, the first base station 310 and the second base station 320) in a physically different location, and received by the electronic device 101 The first signal 311 and the second signal 321 may have different magnitudes (or levels). For example, the signal check module 371 is a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), or a signal to interference noise ratio (SINR) for the first signal 311. ) Can be measured (or checked). The signal check module 371 may measure at least one of RSRP, RSSI, RSRQ, and SINR for the second signal 321. The signal check module 371 may transmit measured information (eg, at least one of RSRP, RSSI, RSRQ, or SINR) for the first signal 311 and the second signal 321 to the signal saturation check module 373. have. The signal check module 371 may periodically or selectively check a signal level for each of the first and second signals 311 and 321, and transmit the check result to the signal saturation check module 373.

The signal saturation check module 373 may check whether signal saturation occurs based on information measured for the first signal 311 and the second signal 321. Since the first signal 311 and the second signal 321 are amplified through the first low noise amplifier 350 and the second low noise amplifier 241, the signal saturation check module 373 2 It can be checked whether all of the signals 321 can be amplified without saturation. When signal saturation occurs, one of the first signal 311 or the second signal 321 may be removed. When either the first signal 311 or the second signal 321 is removed, the first SIM and the second SIM may not simultaneously receive the signal. The signal saturation check module 373 prevents signal saturation by adjusting the gain of the first low-noise amplifier 350 or the second low-noise amplifier 241, thereby controlling the first and second shims to simultaneously receive signals. can do.

According to various embodiments, the signal saturation check module 373 may obtain a first gain set in the first low noise amplifier 350 and a second gain set in the second low noise amplifier 241 from the gain control module 377. I can. The signal saturation check module 373 may determine whether saturation between the first signal 311 and the second signal 321 occurs based on the first gain or the second gain. For example, the signal saturation check module 373 may determine whether a level difference between the first signal 311 and the second signal 321 is less than or equal to a threshold (eg, 20 dB). The signal saturation check module 373 may activate a dual sim simultaneous support function when the level difference is less than or equal to a threshold. The signal saturation check module 373 may request a gain calculation from the gain calculation module 375 when the signal level difference exceeds a threshold value.

According to various embodiments, the signal saturation check module 373 may periodically or selectively check signal saturation. When the signal saturation check module 373 receives the completion of the gain change from the gain control module 377, the signal saturation is performed based on the measured information for the first signal 311 and the second signal 321 after the gain change. You can check whether or not. The signal saturation check module 373 may request a gain calculation from the gain calculation module 375 when the signal level difference exceeds the first range to the third range in the threshold value. The signal saturation check module 373 may deactivate (or terminate) a dual-sim simultaneous support function when the signal level difference exceeds the fourth range in the threshold. The fourth range may be a larger value than the third range. Alternatively, the signal saturation check module 373 may deactivate a dual sim simultaneous support function when receiving a gain change impossibility from the gain control module 377.

The gain calculation module 375 may calculate (or calculate) the first gain or the second gain based on a level difference between the first signal 311 and the second signal 321. The gain may mean a degree to which an amplifier (eg, the first low-noise amplifier 350 and the second low-noise amplifier 241) amplifies a signal. Adjusting the gain is to increase signal quality, and the gain calculating module 375 may calculate an appropriate gain to amplify the first signal 311 and the second signal 321 without signal saturation. The gain calculating module 375 may calculate either one of the first gain and the second gain or calculate both the first gain and the second gain based on the level difference.

For example, the gain operation module 375 may calculate the first gain of the first low noise amplifier 350 when the level difference exceeds a first range (eg, 3 dB) from a threshold. The gain operation module 375 may calculate the second gain of the second low noise amplifier 241 when the level difference exceeds a second range (eg, 5 dB) from the threshold. Alternatively, the gain calculation module 375 may calculate the first gain and the second gain, respectively, when the level difference exceeds a third range (eg, greater than 5 dB) from a threshold. The gain calculation module 375 may transfer the calculated gain to the gain control module 377.

According to various embodiments, the gain calculation module 375 may not calculate a gain when the level difference exceeds a fourth range (eg, 10 dB) from a threshold. If the level difference is out of the fourth range, signal saturation may occur even if the gain of each amplifier is adjusted. In this case, the gain calculation module 375 may transfer the gain calculation to the gain control module 377 because gain calculation is impossible.

The gain control module 377 may control a gain of the first low noise amplifier 350 or the second low noise amplifier 241 based on the gain obtained from the gain operation module 375. For example, the gain control module 377 may change the first gain of the first low noise amplifier 350. Alternatively, the gain control module 377 may change the second gain of the second low noise amplifier 241. When the gain change is completed, the gain control module 377 may transmit the completion of the gain change to the signal saturation check module 373. Alternatively, when the gain control module 377 receives notification from the gain calculation module 375 that the gain calculation is impossible, it may transmit that the gain cannot be changed to the signal saturation check module 373.

If the third antenna module 215 and the fourth antenna module 217 set different reception paths as the second shim, but the first shim and the second shim use frequency signals of the same band, the second shim The deliberation receiving path may be changed to be the same as the first deliberation receiving route.

For example, the processor 120 is based on a level difference between the first signal for the first shim and the second signal for the second shim, the low-noise amplifier included in the RFFE (for example, the first RFFE 221 in FIG. 3) ( Example: the gain of the first low-noise amplifier 350 (for example, the first gain) or the gain of the low-noise amplifier (for example, the second low-noise amplifier 241) included in an RFIC (for example, the RFIC 230 of FIG. 3) (Example: 2nd gain) can be calculated. The processor 120 may calculate both the first gain and the second gain based on the level difference, or may calculate any one of the first gain or the second gain.

According to various embodiments, the processor 120 may calculate the first gain of the first low noise amplifier 350 when the level difference exceeds a first range (eg, 3 dB) from a threshold. The processor 120 may calculate the second gain of the second low noise amplifier 241 when the level difference exceeds a second range (eg, 5 dB) from the threshold. Alternatively, the processor 120 may calculate the first gain and the second gain, respectively, when the level difference exceeds a third range (eg, exceeding 5 dB) in the threshold. The processor 120 may not calculate the gain when the level difference exceeds the fourth range (eg, 10 dB) from the threshold.

In operation 703, the processor 120 may change the LNA gain. The processor 120 may change the first gain of the first low-noise amplifier 350 or the second gain of the second low-noise amplifier 241 using the calculated gain. The processor 120 may change the first gain of the first low noise amplifier 350 and the second gain of the second low noise amplifier 241.

In operation 707, the processor 120 may identify (or determine) whether the difference between the levels is less than or equal to a threshold. The processor 120 may perform operation 709 when the difference between signal levels is less than or equal to the threshold value, and may perform operation 711 when the difference between signal levels exceeds the threshold value.

When the difference between the signal levels is less than or equal to the threshold, in operation 709, the processor 120 may activate the dual SIM simultaneous support function. After adjusting the gain of the first low-noise amplifier 350 or the second low-noise amplifier 241, the processor 120 may activate a dual sim simultaneous support function when a difference between signal levels is less than or equal to a threshold. The processor 120 may control to simultaneously receive a first signal for the first SIM and a second signal for the second SIM by activating a dual SIM simultaneous support function.

If the difference between the signal levels exceeds the threshold, in operation 711, the processor 120 may disable (or terminate) the dual SIM simultaneous support function. Even after gain adjustment of the first low noise amplifier 350 or the second low noise amplifier 241, the processor 120 may deactivate the dual sim simultaneous support function when the difference between signal levels exceeds a threshold. Deactivating the simultaneous dual-sim support function may be controlling so that a signal can be received only through one of the first and second SIMs.
