Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and more specifically, to a control method and apparatus for a power supply device, a chip, a terminal device, and a storage medium. Background Art

[0002] When making a call in the connected discontinuous reception (CDRX) mode, the power supply device will supply power to the power amplifier (PA) according to the CDRX cycle. That is to say, during the activation period of CDRX, the power supply device is turned on to supply power to the PA; during the dormant period of CDRX, the power supply device is turned off to disconnect the power supply to the PA, thereby saving power. However, the frequent turning on and off of the power supply device will cause the voltage ripple amplitude at the PA end to be relatively large, which will cause the capacitor device in the PA to produce capacitor howling. This capacitor howling will interfere with the call quality and the user experience is poor. Summary of the invention

The communication device may also include other devices in the communication system 100, such as a network controller, a mobile management entity, and other network entities, which are not limited in the embodiments of the present application.

[0036] For ease of understanding, the CDRX mechanism in the embodiments of the present application is introduced below.

[0037] CDRX

[0038] In order to reduce the power consumption of user terminals, both LTE and NR systems have a connected discontinuous reception (CDRX) mechanism. The CDRX mechanism includes configuring a CDRX cycle for a terminal in a radio resource control (RRC) connected state. Figure 2 A schematic diagram of a CDRX cycle is shown, such as Figure 2 As shown in FIG. 1 , a CDRX cycle consists of an "onduration" and an "opportunity for CDRX". During the onduration, the terminal device monitors and receives downlink channels and signals including the physical downlink control channel (PDCCH). During the dormancy, the terminal does not receive downlink channels and signals such as PDCCH to reduce power consumption.

[0039] The power amplifier PA is an important component in the RF system. At present, the RF power amplifier is mainly powered by the power management unit (PA power manager unit, PAPMU) of the power amplifier. The power management unit PAPMU of the power amplifier can refer to a power chip. In order to save power, the PAPMU in the terminal device can use average power tracking (APT) or envelope tracking (ET) and other power supply modes to power the PA.

[0040] At present, when making a call in CDRX mode, PAPMU will power PA according to the CDRX cycle. That is to say, during the activation period of CDRX, PAPMU is set to the activation state (which may refer to starting PAPMU) and PAPMU is used to power PA; during the dormant period of CDRX, PAPMU is set to the dormant state (which may refer to shutting down PAPMU) and the power supply to PA is disconnected, thereby saving the power of the terminal device to the greatest extent. However, with the frequent startup and shutdown of PAPMU in the CDRX cycle, the voltage ripple amplitude at the PA end will be relatively large, which will cause the capacitor devices in the PA to produce capacitor howling. This capacitor howling will generate noise, interfere with the call quality, and poor user experience.

[0041] In order to solve the above problems, the embodiment of the present application provides a control method for a power supply device. During the first call in the CDRX mode, in response to the preset condition being met (for example, the first call is in a call state, and the handset of the terminal device is close to the user's ear), the power supply device is configured to be in an activated state during the activation period and the dormant period of the CDRX mode to supply power to the PA. Compared with the traditional solution of frequently turning on and off the power supply device with the CDRX cycle, this solution can effectively avoid the phenomenon of capacitor howling and improve the user experience.

[0042] It should be noted that the type and power amplification level of the power amplifier in the embodiment of the present application are not specifically limited. The power amplifier in the embodiment of the present application is an important component of the radio frequency system and can be used to perform power amplification processing on the radio frequency signal of the first call.

[0043] The power supply device in the embodiment of the present application can be electrically connected to the above-mentioned power amplifier to supply power to the power amplifier. The power supply device can refer to a power management unit of the power amplifier. The power supply device can be, for example, a power chip of the PA, such as an APT power chip or an ET power chip, etc. The present application does not impose any specific restrictions on this.

[0044] Combined with the following Figure 3 The control method of the power supply device in the embodiment of the present application is described in detail. Figure 3 As shown, the control method 300 of the power supply device may include steps S310 to S320.

[0045] In step S310, a first call is made in a connected discontinuous reception (CDRX) mode.

[0046] The first call can be a voice call or a video call, and this application does not impose any specific restrictions on this.

[0047] This application does not specifically limit the type of the first call. Taking a voice call as an example, for example, the first call in a 4G network can be a voice over long-term evolution (VoLTE); the first call in a 5G network can be a voice over new radio (VoNR). Of course, the first call can also be a VoWIFI, that is, a voice call in a Wi-Fi network.

[0048] In step S320 , in response to the preset condition being met, the power supply device is configured to be in an active state during the active period and the sleep period of the CDRX mode to supply power to the power amplifier.

[0049] In some embodiments, in response to the preset condition not being met, the power supply device can be configured to be in an active state during the active period of the CDRX cycle to supply power to the power amplifier, and can be configured to be in a sleep state during the sleep period of the CDRX cycle to shut down the power supply device.

[0050] In some embodiments, the preset condition may include any one of the following conditions: the first call is in a call state; the receiver of the terminal device is close to the ear of the user; the first call is in a call state, and the receiver of the terminal device is close to the ear of the user; the network frequency band of the first call is N41 or N78, the first call is in a call state, and the receiver of the terminal device is close to the ear of the user. The following takes the preset condition of "the first call is in a call state" or "the first call is in a call state, and the receiver of the terminal device is close to the ear of the user" as an example to illustrate the configuration of the power supply device.

[0051] As an example, for the preset condition of "the first call is in the call state", when the first call of the terminal device is in the call state (that is, the preset condition is met), the power supply device can be configured to be in the activation state during the activation period and the dormant period of the CDRX mode to supply power to the power amplifier. Since the power supply device is set to be in the working state all the time during the first call, the phenomenon of capacitor howling can be effectively avoided. Further, when the first call ends (that is, the preset condition is not met), the power supply device can be controlled to be turned on or off according to the activation and dormant states of the CDRX cycle to supply power to the power amplifier without setting the power supply device to be in the working state all the time, thereby saving power more effectively. It should be understood that when the first call ends, even if there is a capacitor howling phenomenon, the capacitor howling has little impact on the user. Therefore, the impact of the capacitor howling can be ignored, and the power supply mode of the power supply device can be restored to control the power supply device to be turned on or off according to the activation period and the dormant period of the CDRX cycle (that is, the power supply device is configured to be in the activation state during the activation period, and the power supply device is configured to be in the dormant state during the dormant period).

[0052] As another example, for the preset condition of "the first call is in a call state, and the earpiece of the terminal device is close to the ear of the user", when the first call of the terminal device is in a call state, and the earpiece of the terminal device is close to the ear of the user (that is, the preset condition is met), the power supply device can be configured to be in an activated state during the activation period and the dormant period of the CDRX mode to supply power to the power amplifier. Since the power supply device is set to a constant working state only when the earpiece is close to the ear of the user during the first call, the phenomenon of capacitive howling can be more effectively avoided. It should be understood that even if the first call is not ended, if the earpiece is away from the ear of the user, the power supply device can still be controlled to be turned on or off according to the activation and dormant states of the CDRX cycle to supply power to the power amplifier without having to set the power supply device to a constant working state, thereby saving power more effectively. It is understandable that as long as the earpiece is not next to the user's ear, capacitive howling will not have much impact on the user. Therefore, the impact of capacitive howling can be ignored and the power supply mode of the power supply device can be restored to control the power supply device to be turned on or off according to the activation period and sleep period of the CDRX cycle (that is, the power supply device is configured to be in an activated state during the activation period, and the power supply device is configured to be in a sleep state during the sleep period).

[0053] It should be noted that the power supply device being in an activated state may indicate that the power supply device is in a startup state or a working state; the power supply device being in a dormant state may indicate that the power supply device is in a shutdown state or a non-working state.

[0054] In some embodiments, a distance sensor may be provided in the terminal device, and the distance sensor may be used to detect whether the earpiece of the terminal device is close to the ear of the user. Furthermore, a first threshold may be set, and the first threshold is a distance threshold between the earpiece of the terminal device and the ear of the user. When the distance between the earpiece of the terminal device and the ear of the user is less than the first threshold, it may be determined that the earpiece of the terminal device is close to the ear of the user, otherwise, it is determined that the earpiece of the terminal device is not close to the ear of the user.

[0055] In some embodiments, before making a first call in the CDRX mode, the preset condition may be configured, for example, a first configuration message sent by a network device may be received, the first configuration message being used to configure the preset condition; then, the preset condition is configured according to the first configuration message. The network device may be, for example, a manufacturer server of the terminal device. In some embodiments, configuring the preset condition using the first configuration message may also be referred to as updating the service RUS.

[0056] In some embodiments, the configuration of the power supply device may be ping-pong switching. For example, the user holding the terminal device may be constantly close to and away from the ear, that is, when close to the ear, the configuration of the power supply device can be switched to "configure the power supply device to an activated state during the activation period and the dormant period of the CDRX cycle" (for the convenience of description, the configuration mode of the power supply device may be referred to as the first mode below); when far away from the ear, the configuration of the power supply device can be switched to "configure the power supply device to an activated state during the activation period of the CDRX cycle and configure the power supply device to a dormant state during the dormant period of the CDRX cycle" (for the convenience of description, the configuration mode of the power supply device may be referred to as the second mode below). In order to prevent the situation of ping-pong switching, the embodiment of the present application may set a first timer. As an example, if the preset condition is not met and the first timer times out, it is switched to the second mode, wherein the first timer is used to determine the duration after the preset condition is met. That is to say, the timing starts after the preset condition is met. If the time of the timer has not arrived, even if the preset condition is converted from a satisfied state to an unsatisfied state, it will not switch to the second mode, but will maintain the first mode. That is, if the preset condition is not satisfied and the first timer has not timed out, the power supply device is kept in an active state during the active period and the dormant period of the CDRX cycle, thereby effectively preventing ping-pong switching.

[0057] In some embodiments, in response to the preset condition being met, the value of the EFS configuration file of the power supply device may be updated to 1, and a first timer may be started. The first timer may be a software timer in the terminal device to achieve automatic timing. Of course, it may also be a hardware timer, and this application does not impose any specific restrictions on this.

[0058] The embodiment of the present application does not impose any specific limitation on the time threshold for determining the first timing timeout, and can be set according to demand, for example, can be set to 10ms.

[0059] It is understandable that when the preset condition is not met and the first timer times out, the second mode can be switched, and the first timer needs to be reset, waiting for the next preset condition to be met to trigger the first timer.

[0060] In some embodiments, the terminal device includes a radio interface layer (RIL) and a modem layer, and the power supply device is configured to be in an active state during the activation period and the dormant period of the CDRX mode to supply power to the power amplifier, which may include: calling a second configuration message through the RIL layer, the second configuration message is used to configure the power supply device to be in an active state during the activation period and the dormant period; then, using the RIL layer to send the second configuration message to the Modem layer; then, according to the second configuration message, the power supply device can be configured to be in an active state during the activation period and the dormant period using the Modem layer to supply power to the power amplifier. Among them, the second configuration message can carry configuration parameters of preset conditions, and the second configuration message can be, for example, a Qualcomm messaging interface (QMI) message. It should be understood that after the configuration is completed on the modem side, the EFS configuration file of the power supply device can be updated so that the actual state of the power supply device is synchronized with the parameters in the EFS configuration. At the same time, the configuration result (for example, an ACK message) can also be reported to the application layer, so that the current configuration operation can be confirmed to have been successful.

[0061] In some embodiments, for a terminal device based on the Android system, the system architecture of the terminal device can be divided into four layers from bottom to top: a Modem layer, a RIL layer, a framework layer, and an application layer.

[0062] In some embodiments, the Modem layer may include a Modem chip, and the Modem chip may be used to configure the power on / off state of the power supply device.

[0063] In some embodiments, the network frequency band where the first call is located may be N41, N78, etc., and this application does not impose any specific limitation on this.

[0064] In order to deepen the understanding of the control method of the above power supply device, the following Figure 4 The control method of the power supply device in the embodiment of the present application is illustrated in more detail.

[0065] Figure 4 Another control method of a power supply device provided in an embodiment of the present application is as follows: Figure 4 As shown, the control method of the power supply device may include the following steps: S401-S412.

[0066] In step S401: configure preset conditions. For example, the preset conditions may include any one of the following conditions: the receiver of the terminal device is close to the ear of the user; the first call is in a call state; the first call is in a call state, and the receiver of the terminal device is close to the ear of the user; the first call is in a call state, and the network frequency band of the first call is N41 or N78; the network frequency band of the first call is N41 or N78, the first call is in a call state, and the receiver of the terminal device is close to the ear of the user. The first call can be a video call or a voice call. The first call can be, for example, VoNR or VoWIFI. The configuration of the above preset conditions can be updated through RUS, so that more free settings can be achieved. The following takes the preset condition that the first call is a target call and the receiver of the terminal device is close to the ear of the user as an example to illustrate the subsequent steps. The target call can be, for example, an N41 call or VoWIFI.

[0067] In step S402: a first call is made in the CDRX mode, and a distance sensor is used to determine in real time the distance between the user's ear and the receiver of the terminal device.

[0068] In step S403: determine whether the receiver of the terminal device is close to the user's ear, if so, jump to step S405, if not, jump to step S404.

[0069] In step S404: the power supply device is configured to be in an active state during the activation period and the dormant period of the CDRX cycle, so that during a call close to the user's ear, the phenomenon of capacitive howling can be effectively prevented, thereby improving the user experience. It should be understood that before configuring the power supply device, the CDRX information of the current network configuration should also be read, and the CDRX information includes information such as the activation period and the dormant period of the CDRX cycle.

[0070] In step S405: the network calls are classified according to the network call type. For example, the first call can be an N41 call, an N78 call, a VoWIFI call, etc.

[0071] In step S406: determine whether the first call is a target call. The target call may be, for example, an N41 call or a VoWIFI call, etc. If it is a target call, jump to step S407, otherwise, jump to step S404.

[0072] In step S407: the QMI message is sent to the modem chip for processing. For example, the QMI message can be called at the RIL layer and sent to the modem chip for processing.

[0073] In step S408: the power supply device is configured to be in an active state using the modem chip during the active period and the dormant period of the CDRX cycle.

[0074] In step S409: in response to the preset condition being met, a first timer is started. The first timer may be the first timer described above, which will not be described in detail here.

[0075] In step S410: determine whether there is ping-pong. That is, determine whether there is ping-pong switching between the first mode and the second mode. If yes, jump to step S411, otherwise, jump to step S412.

[0076] In step S411: continue monitoring. In some embodiments, in response to the existence of ping-pong switching, the timing duration of the first timer may be adjusted to avoid the situation of ping-pong switching.

[0077] In step S412: end the current process.

[0078] Combination of the above Figures 1 to 4 The method embodiment of the present application is described in detail.
