Description

Communication control method and device of mobile terminal, storage medium and electronic equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication control method of a mobile terminal, a communication control device, and a computer-readable storage medium.

Background

UWB (Ultra Wide band) is a carrier-free communication technology that can transmit data using non-sinusoidal narrow pulses on the nanosecond to picosecond level by transmitting signals of extremely low power over a Wide frequency spectrum. Because UWB has many advantages such as strong anti-interference performance, high transmission rate, and small transmission power, UWB is widely used in the fields of indoor communication, high-speed wireless LAN (Local Area Network), security detection, radar, and the like.

In practical applications, the UWB unit is usually built in the mobile terminal, and when the mobile terminal is in a power-off state, the UWB communication process cannot be performed. Based on this, the prior art proposes that when the mobile terminal is in the power-off state, a Communication process with other terminal devices may be implemented through NFC (Near Field Communication) technology. However, the usage requirement of the NFC technology is high, for example, the effective communication range of NFC is small, and a user needs to actively make the mobile terminal close to the card reading device, which is difficult to implement a long-distance and non-sensing communication process, and the user experience is poor.

Therefore, how to perform an effective and convenient communication process when the mobile terminal is in a power-off state to provide a good communication experience for a user is a problem to be solved urgently in the prior art.

In the related art, when a mobile terminal performs communication by using the UWB technology, in order to avoid a large power consumption caused by the UWB chip being constantly in a radio frequency signal receiving state, a trigger signal is generally transmitted to the UWB chip by an Application Processor (AP) disposed in the mobile terminal, so that the UWB chip starts receiving a radio frequency signal transmitted from a peripheral object, thereby performing the UWB communication. When the mobile terminal cannot work, for example, in a power-off state, the AP cannot work normally, and then the AP cannot send a trigger signal to the UWB chip, thereby implementing UWB communication.

The following specifically describes a communication control method of a mobile terminal and a communication control apparatus of a mobile terminal according to exemplary embodiments of the present disclosure.

Fig. 3 shows a flow of a communication control method of a mobile terminal in the present exemplary embodiment, including the following steps S310 to S330:

step S310, in the power-off state of the mobile terminal, monitoring a bluetooth signal through the bluetooth unit.

In practical applications, the mobile terminal may enter a power-off state due to a power-off operation of a user or a low power level, and in the power-off state, the AP cannot normally operate, so that the AP cannot directly send a trigger signal for receiving a radio frequency signal of an ambient environment to the UWB chip. Based on this, in the exemplary embodiment, when the mobile terminal is in the power-off state, the trigger signal may be set to be sent by the bluetooth unit, where the bluetooth unit is a part configured in the mobile terminal, and is configured to monitor bluetooth signals of other terminal devices, or receive bluetooth signals of other terminal devices, and the like, and perform bluetooth communication, and may be a bluetooth chip configured in the mobile terminal.

In the exemplary embodiment, when it is detected that the mobile terminal is in the power-off state, the bluetooth unit may monitor whether there is another terminal device in the surrounding environment to send a bluetooth signal, for example, a bluetooth signal sent by an access control system device, or a bluetooth signal sent by an in-vehicle device for managing a lock, or the like. The bluetooth signal may include data such as an identification of a bluetooth sensor provided in the terminal device, or an intensity of the bluetooth signal. In this exemplary embodiment, the bluetooth unit may continuously perform the monitoring action, and send the monitored data to the system or the server for processing in real time, or may periodically perform the monitoring action, and package the monitored data of one or more periods and send the packaged monitored data to the system or the server for processing, and the like.

In an exemplary embodiment, the communication control method of the mobile terminal may further include:

and when the power supply signal output by the power supply management unit is not detected, determining that the mobile terminal is in a power-off state.

Generally, in order to provide Power to the mobile terminal and enable the mobile terminal to be powered on, a Power Management Unit (PMU) is configured in the mobile terminal, and this exemplary embodiment may determine whether the mobile terminal is in a Power-off state by determining an output signal of the PMU Power, and when the mobile terminal is in a Power-on state, the PMU may output a Power signal; when the mobile terminal is in the power-off state, the PMU cannot output the power signal. Therefore, based on the judgment of whether the PMU outputs the power signal, the mobile terminal can be determined to be in the power-on state or the power-off state currently.

when the mobile terminal is powered off, the control circuit of the Bluetooth unit is switched to the micro control unit, so that the Bluetooth unit is controlled by the micro control unit to monitor Bluetooth signals in the power-off state of the mobile terminal.

Generally, when the mobile terminal is in the power-on state, the bluetooth unit is controlled by the AP or other processor of the mobile terminal, and the AP cannot work when the mobile terminal is in the power-off state. In order to enable the bluetooth Unit to still enter a specific mode in the power-off state to monitor and detect other bluetooth signals, in this exemplary embodiment, when it is detected that the mobile terminal is powered off, for example, when it is detected that a user performs a power-off operation, or when the mobile terminal triggers an automatic power-off due to a low power, the control circuit of the bluetooth Unit may be switched from the AP to an MCU (micro controller Unit). The MCU can be connected to a device which can output power signals when the mobile terminal is in a power-off state.

In an exemplary embodiment, the switching the control circuit of the bluetooth unit to the micro control unit may include:

the I2C (Inter-Integrated Circuit) bus of the bluetooth unit is switched to the micro control unit.

In the present exemplary embodiment, an I2C bus switch may be provided for switching control operations of the AP and the MCU, and when it is detected that the mobile terminal is powered off, the bluetooth unit may be controlled by the AP and the bluetooth unit may be controlled by the MCU.

In an exemplary embodiment, the step S310 may include:

and controlling the Bluetooth unit to monitor the Bluetooth signal in a low power consumption mode in the power-off state of the mobile terminal.

Since the low power consumption technology has an ultra-low peak value, an average value, and standby power consumption, in order to reduce power consumption, the exemplary embodiment may control the bluetooth unit to listen to the bluetooth signal in the low power consumption mode in the power-off state of the mobile terminal. Generally, the bluetooth low energy (bluetooth low energy) design can provide 3 application schemes, Stand-alone Mode, Dual Mode, and integrated Mode. In the exemplary embodiment, after the mobile terminal is powered off, the bluetooth unit may enter the Stand-alone mode, and the bluetooth low energy may listen to the bluetooth signal of the surrounding environment.

And step S320, when the Bluetooth signal sent by the target object is monitored, waking up the ultra-wideband UWB unit.

When the mobile terminal monitors a bluetooth signal of a surrounding environment through the bluetooth unit, a plurality of terminal devices may exist in the surrounding environment, and these terminal devices may all be configured with a bluetooth sensor, such as a bluetooth beacon, and the bluetooth sensor may send an ID (identity, account number) unique to itself to the surrounding, so that a receiving end may scan the bluetooth sensor and analyze a signal sent by the bluetooth sensor, so as to implement positioning or other functions, that is, the mobile terminal may monitor that the surrounding environment includes the bluetooth signal sent by the plurality of terminal devices, for example, a vehicle-mounted device configured by a plurality of vehicles may send a bluetooth signal in a garage. The target object is a terminal device associated with the mobile terminal and requiring control operation through the mobile terminal, for example, a vehicle-mounted device that is the same as a user using the mobile terminal or can perform control operation such as unlocking or closing a vehicle lock through the mobile terminal used by the user.

The UWB unit refers to a portion provided in the mobile terminal and used for signal transmission with other terminal devices by the UWB technique, for example, a UWB chip provided in the mobile terminal. In the exemplary embodiment, after the mobile terminal monitors the surrounding environment including the bluetooth signal transmitted by the target object, the mobile terminal may pair with the target object according to the bluetooth signal, and after the pairing is successful, an interrupt signal may be transmitted to the UWB unit to wake up the UWB unit for UWB communication. In consideration of the fact that in practical applications, in order to reduce the power consumption of the UWB unit, the UWB unit is often in a deep sleep state in a state where it is not necessary to receive a radio frequency signal, and therefore, in order to avoid a situation where it is unsuccessful to wake up the UWB unit, the exemplary embodiment may further set a mechanism for periodically sending an interrupt signal to the UWB unit after pairing is successful, so as to ensure that the UWB unit can be effectively woken up.

In an exemplary embodiment, the step S320 may include:

when the session identification in the received bluetooth signal matches successfully with the identification corresponding to the target object, the UWB unit is awakened.

The identification of the target object refers to preset information capable of reflecting the identity of the target object, for example, an ID of a bluetooth sensor configured on the target object, and the bluetooth sensor can be uniquely determined according to the ID. The exemplary embodiment may match the received session identifier with the identifier of the target object to determine whether the received session identifier is the identifier of the target object, and when the matching is successful, may determine that the received session identifier is the identifier corresponding to the target object, thereby executing the procedure of waking up the UWB unit.

In order to enable the mobile terminal to still input power in the power-off state, so as to wake up the UWB unit through the bluetooth unit for normal UWB communication, the power input terminal of the bluetooth unit and the power input terminal of the UWB unit may be connected to a voltage Regulator device, such as an LDO (Low Dropout Regulator), which is still capable of outputting a power signal in the power-off state of the mobile terminal. In this exemplary embodiment, the enable signal of the voltage regulator device may be kept in an on state in the power-off state of the mobile terminal, so that the voltage regulator device, such as the LDO, can normally output electric energy no matter the mobile terminal is in the power-on state or the power-off state.

And step S330, carrying out ultra-wideband communication with the target object through the UWB unit.

In the present exemplary embodiment, ultra-wideband communication may be performed with a target object based on a UWB unit while the mobile terminal is in a power-off state. Specifically, according to different application scenarios, the functions realized by the ultra-wideband communication are diversified, for example, a user can open an access control system, unlock a car lock or open an engine through a mobile terminal. It should be noted that, in order to ensure the security of communication between the mobile terminal and the target object, the exemplary embodiment may further enable the mobile terminal to send specific information to the target object, or receive and process information sent by the target object, and return a processing result to the target object, so that the target object verifies the identity of the mobile terminal, and the like. In addition, when the UWB unit and the target object carry out the ultra-wideband communication and realize the corresponding function, the UWB unit can also enter the sleep state again to save the power consumption.

In an exemplary embodiment, as shown in fig. 4, the step S330 may include the following steps:

step S410, receiving first information sent by a target object through ultra-wideband communication;

step S420, decrypting the first information by adopting a secret key to obtain second information;

and step S430, sending second information to the target object through ultra-wideband communication, so that the target object triggers a preset event when the second information is verified to pass.

The first information refers to information used for performing mobile terminal identity authentication in the environment around the target object, for example, the vehicle-mounted device may send a UWB radio frequency signal used for authenticating the security of the mobile terminal to a receiving end around the vehicle-mounted device. After receiving the first information, the mobile terminal may obtain the stored key from the security chip, such as the eSE, and decrypt the first information according to the key to obtain the second information. Then, the mobile terminal may return the second information to the target object through UWB, so that the target object determines whether the identity of the mobile terminal is verified, and triggers a preset event when it is determined that the identity of the mobile terminal is legal or secure. In the exemplary embodiment, the target object may include an in-vehicle intelligent system, and the preset event may include unlocking a door and/or starting an engine of the vehicle. Under the scene that the mobile terminal unlocks the vehicle door through the UWB technology, the mobile terminal receives first information sent by a target vehicle-mounted intelligent system, decrypts the first information through a secret key to obtain second information and returns the second information to the target vehicle-mounted intelligent system, the target vehicle-mounted intelligent system determines whether the identity of the mobile terminal passes verification or not by judging whether the second information meets the requirement, and the vehicle door can be unlocked when the second information passes verification.

receiving third information sent by the target object through ultra-wideband communication, and controlling the UWB unit to enter a sleep mode;

and the third information is feedback information after a preset event is triggered.

After the mobile terminal receives the second information sent by the target object, it may be determined that a preset event has been triggered, and further, in order to save power consumption, the UWB unit may be controlled to enter the sleep mode again. Taking the scenario of unlocking the car door as an example, after the mobile terminal passes the verification and triggers the event of unlocking the car lock, the target vehicle-mounted intelligent system may return third information through the UWB to inform the mobile terminal that the current car lock is unlocked, and at this time, the mobile terminal may control the UWB unit to enter the sleep mode again. According to the present exemplary embodiment, whether the UWB unit needs to enter the sleep mode can be adaptively adjusted according to the current application requirements, and in the process, the user does not sense the UWB unit, that is, power consumption can be saved, and a good communication experience can be provided for the user.

Fig. 5 is a flowchart illustrating another communication control of a mobile terminal in this exemplary embodiment, which may specifically include the following steps:

step S502, when the mobile terminal is powered off, the I2C bus of the Bluetooth unit is switched to the micro control unit;

step S504, the Bluetooth unit is controlled by the micro control unit to monitor Bluetooth signals;

step S506, judging whether the session identification in the received Bluetooth signal is successfully matched with the identification corresponding to the target object;

when the matching is unsuccessful, returning to the step S504, and continuing to execute the step of controlling the Bluetooth unit to monitor the Bluetooth signal through the micro control unit;

when the matching is successful, executing step S508, and sending an interrupt signal to the UWB unit;

step S510, waking up the UWB unit;

step S512, receiving first information sent by a target object through ultra-wideband communication;

step S514, decrypting the first information by using the key to obtain second information;

step S516, sending second information to the target object through ultra-wideband communication, so that the target object verifies the validity of the identity of the mobile terminal;

when the verification is passed, executing step S518 to trigger a preset event;

step S520, receiving third information sent by the target object through ultra-wideband communication, and controlling the UWB unit to enter a sleep mode;

when the verification fails, it indicates that the mobile terminal currently performing the ultra-wideband communication may have a potential safety hazard, then step S522 is executed, and the current flow is ended.

To sum up, in the present exemplary embodiment, in the power-off state of the mobile terminal, the bluetooth unit monitors the bluetooth signal; waking up an ultra-wideband UWB unit when a Bluetooth signal sent by a target object is monitored; and carrying out ultra-wideband communication with the target object through the UWB unit. On one hand, the present exemplary embodiment provides a new communication control method for a mobile terminal, which can wake up a UWB unit through bluetooth when the mobile terminal is in a power-off state to perform a UWB communication process, and has high signal transmission efficiency and low power consumption; on the other hand, compared with the prior art, in the exemplary embodiment, when the mobile terminal is powered off, the NFC technology is used for communication, so that the user can perform a remote and non-aware communication process while the signal transmission efficiency is ensured; on the other hand, in the communication control method of the mobile terminal, the Bluetooth unit of the mobile terminal monitors and receives the Bluetooth signal, so that the UWB unit can be awakened, the process is simple and convenient, other additional devices are not required to be arranged, the hardware cost is low, and the application scene is wide.

An exemplary embodiment of the present disclosure also provides a communication control apparatus, as shown in fig. 6, the communication control apparatus 600 may include:

a micro control unit 610.

And a bluetooth unit 620, wherein a control circuit of the bluetooth unit 620 is connected with the micro control unit, so that the micro control unit controls the bluetooth unit when the mobile terminal is in an off state.

The bluetooth unit 610 may monitor whether the surrounding environment includes that other terminal devices send bluetooth signals, for example, bluetooth signals sent by an access control system device, or bluetooth signals sent by a vehicle-mounted device for managing a lock, when it is detected that the mobile terminal is in a power-off state. Generally, when the mobile terminal is in the power-on state, the bluetooth unit is controlled by the AP or other processors of the mobile terminal, and when the mobile terminal is in the power-off state, the AP cannot normally operate. Based on this, the present exemplary embodiment connects the control circuit of the bluetooth unit 620 with the micro control unit 610, so that the micro control unit 610 controls the bluetooth unit 620 in the power-off state of the mobile terminal, receives bluetooth signals in the surrounding environment, and receives bluetooth signals transmitted by the target object. The mcu 610 may be configured to be connected to a device capable of outputting a power signal even when the mobile terminal is in a power-off state. The target object is a terminal device that has an association relationship with the mobile terminal and needs to be controlled by the mobile terminal, for example, a vehicle-mounted device that is the same as a user using the mobile terminal or can be controlled by the mobile terminal used by the user to open or close a vehicle lock. When bluetooth unit 620 receives a bluetooth signal transmitted by a target object, UWB unit 630 may be awakened.

And the UWB unit 630 is electrically connected with the Bluetooth unit 620, and can trigger the UWB communication with the target object when receiving the interrupt signal sent by the Bluetooth unit 620.

The UWB unit 630 refers to a unit provided in the mobile terminal and used for signal transmission with other terminal devices by UWB technology, for example, a UWB chip provided in the mobile terminal. In the present exemplary embodiment, UWB unit 630 is electrically connected to bluetooth unit 620, that is, UWB unit 620 and UWB unit 630 may be wired into a circuit board, and electrical signals may be transmitted therebetween. In the present exemplary embodiment, after the mobile terminal monitors the surrounding environment including the bluetooth signal transmitted by the target object, the mobile terminal may pair with the target object according to the bluetooth signal, and after the pairing is successful, the bluetooth unit 620 may transmit an interrupt signal to the UWB unit 630 to wake up the UWB unit 630 for UWB communication. In consideration of the fact that in practical applications, in order to reduce the power consumption of the UWB unit 630, the UWB unit 630 is often in a deep sleep state in a state where it is not necessary to receive radio frequency signals, and therefore, in order to avoid a situation where the UWB unit 630 fails to wake up, the exemplary embodiment may further set a mechanism for periodically sending an interrupt signal to the UWB unit 630 after pairing is successful, so as to ensure that the UWB unit 630 can be woken up effectively.

In summary, in the communication control apparatus in the exemplary embodiment, the control circuit of the bluetooth unit is connected to the micro control unit, so that the micro control unit controls the bluetooth unit in the power-off state of the mobile terminal; and the UWB unit is electrically connected with the Bluetooth unit, and when the UWB unit receives the interrupt signal sent by the Bluetooth unit, the process of carrying out ultra-wideband communication with the target object is triggered. On one hand, the communication control device can wake up the UWB unit through the Bluetooth in the power-off state of the mobile terminal to carry out the UWB communication process, so that the signal transmission efficiency is high, and the power consumption is low; on the other hand, when the mobile terminal is powered off, the communication control device carries out UWB communication, so that the signal transmission efficiency is ensured, and meanwhile, a user can carry out a long-distance and non-sensing communication process; on the other hand, the Bluetooth unit monitors and receives the Bluetooth signal, so that the UWB unit can be awakened, the flow is simple and convenient, other additional devices are not required to be arranged, the hardware cost is low, and the application scene is wide.

In an exemplary embodiment, the communication control apparatus may further include:

and the voltage stabilizing device is respectively connected with the power input end of the Bluetooth unit and the power input end of the UWB unit so as to provide power signals for the Bluetooth unit and the UWB unit.

Enabling signals of the voltage stabilizing device are kept on in a power-off state of the mobile terminal; the voltage stabilizing device comprises a low dropout linear voltage regulator or a direct current/direct current converter.

In order to enable the mobile terminal to still input power in the power-off state so as to wake up the UWB unit through the bluetooth unit for normal UWB communication, the exemplary embodiment may connect the power input terminal of the bluetooth unit and the power input terminal of the UWB unit to a voltage Regulator device, such as an LDO (Low Dropout Regulator), which is still capable of outputting a power signal in the power-off state of the mobile terminal. In addition, the power input end of the bluetooth unit and the power input end of the UWB unit may be connected to other devices that can supply power in an off state, such as a DC/DC (Direct Current/Direct Current converter). The LDO is a voltage stabilizing device which utilizes lower working pressure difference and adjusts output voltage through negative feedback to keep the output voltage unchanged. When the voltage difference is small, the LDO can be adopted, and when the voltage difference is large, the DC/DC can be adopted to ensure the input efficiency of the power supply. It should be noted that the voltage regulator device, such as LDO, may be disposed in a mobile terminal, or may be directly integrated into a bluetooth unit or a UWB unit.

The enable signal of the voltage stabilizer can be kept in an on state in the off state of the mobile terminal, so that the voltage stabilizer (such as LDO or DC/DC) can be enabled to normally output electric energy no matter the mobile terminal is in the on state or the off state.

when the mobile terminal is powered off, the two-wire serial bus I2C of the Bluetooth unit is switched to the micro control unit.

When the mobile terminal is successfully matched with the target object, the bluetooth unit 710 may transmit an interrupt signal to the UWB unit 720 to wake up the UWB unit 720 to perform UWB communication with the target object. The bluetooth unit 710 and the UWB unit 720 are configured with a radio frequency matching circuit 711 and a radio frequency matching circuit 721 corresponding to each of them, so as to perform a matching process of antenna impedance.
