For ease of understanding, descriptions of some concepts related to embodiments of this application are provided as examples for reference.

For example, A and/or B may represent the following cases: Only A exists, both A and B exist, and only B exists, where A and B may be singular or plural. In this specification, claims, and accompanying drawings of this application, terms “first”, “second”, “third”, “fourth”, and the like (if exist) are intended to distinguish between similar objects but do not necessarily indicate a specific order or sequence.

To better understand a service data transmission method and a related device provided in embodiments of this application, the following first describes an application scenario of the service data transmission method in this application.

FIG. 1 is a schematic diagram of an application scenario of a service data transmission method according to an embodiment of this application.

The service data transmission method provided in this embodiment of this application is applied to a first electronic device 10 and a second electronic device 11. The first electronic device 10 and the second electronic device 11 may be terminal devices. Particularly, the second electronic device 11 may be a wearable device. In the embodiment shown in FIG. 1, the first electronic device 10 is a mobile phone, and the second electronic device 11 is a watch. The first electronic device 10 and the second electronic device 11 perform a distributed collaborative service. The distributed collaborative service is a service that is processed collaboratively between electronic devices, for example, exercise, music, and message notification. For example, the first electronic device 10 (for example, the mobile phone) and the second electronic device 11 (for example, the watch) run a message notification service. After receiving a message, the first electronic device 10 displays the message on the second electronic device 11, to facilitate a user to view the message. For another example, the first electronic device 10 and the second electronic device 11 run an exercise service. When a user runs, the first electronic device 10 sends information such as a pace and a distance to the second electronic device 11, and the second electronic device 11 generates and displays a running route.

According to the service data transmission method provided in this embodiment of this application, in a process in which the first electronic device 10 and the second electronic device 11 perform the distributed collaborative service, the first electronic device 10 determines a channel for transmitting service data by the first electronic device 10 to the second electronic device 11, to reduce a quantity of times of waking up a main control chip with high energy consumption in the second electronic device 11, and improve standby time of the second electronic device 11.

FIG. 2 is an architectural diagram of a mobile phone and a watch to which a service data transmission method according to an embodiment of this application is applied.

As shown in FIG. 2, the service data transmission method provided in this embodiment of this application is applied to a system including a mobile phone 20 and a watch 21. The mobile phone 20 includes a mobile phone side service 201 and a device management application 202. The watch 21 includes an application processor (Application Processor, AP) 211, a micro control unit (Micro Control Unit, MCU) 212, and a Bluetooth chip 213.

The mobile phone side service 201 is a distributed collaborative application running on the mobile phone 20. The mobile phone 20 interconnects with the watch 21 by running the mobile phone side service 201, to implement distributed collaboration. The mobile phone side service 201 may include a wearable capability (WearEngine), exercise, music, message notification, and the like.

The device management application 202 is configured to: establish a first Bluetooth logical channel with the AP 211 and a second Bluetooth logical channel with the MCU 212, determine a Bluetooth logical channel for sending the service data to the watch 21, and send the service data to the AP 211 or the MCU 212 through the determined Bluetooth logical channel.

The AP 211 is a control chip having a strong processing capability and high energy consumption in the watch 21, and may be referred to as a first main control chip. Energy consumption of the AP 211 during running is, for example, 100 mAH (100 milliamperes per hour), and energy consumption during standby is, for example, 5 mAH (5 milliamperes per hour). The AP 211 may process a distributed collaborative service that has a high performance requirement, for example, the WearEngine and the music, or may process a distributed collaborative service that has a low performance requirement, for example, the message notification.

A difference from the AP 211 is that the MCU 212 is a control chip having a weak processing capability and low energy consumption in the watch 21, and may be referred to as a second main control chip. Energy consumption of the MCU 212 during running is, for example, 50 mAH, and energy consumption during standby is, for example, 10 uAH (10 microamperes per hour). The MCU 212 may process a distributed collaborative service that has a low performance requirement, for example, the message notification.

The Bluetooth chip 213 is configured to: implement data transmission between the mobile phone 20 and the AP 211 through the first Bluetooth logical channel, and implement data transmission between the mobile phone 20 and the MCU 212 through the second Bluetooth logical channel. When the device management application 202 sends data (for example, the service data) to the AP 211 through the first Bluetooth logical channel, the Bluetooth chip 213 receives a channel number and data that correspond to the first Bluetooth logical channel and that are sent by the device management application 202, and forwards the data to the AP 211 based on the channel number corresponding to the first Bluetooth logical channel. When the device management application 202 sends data to the MCU 212 through the second Bluetooth logical channel, the Bluetooth chip 213 receives a channel number and data that correspond to the second Bluetooth logical channel and that are sent by the device management application 202, and forwards the data to the MCU 212 based on the channel number corresponding to the second Bluetooth logical channel.

When the AP 211 sends data to the mobile phone 20 through the first Bluetooth logical channel, the Bluetooth chip 213 receives the data sent by the AP 211, and sends the data to the mobile phone 20. When the MCU 212 sends data to the mobile phone 20 through the second Bluetooth logical channel, the Bluetooth chip 213 receives the data sent by the MCU 212, and sends the data to the mobile phone 20.

Currently, a Bluetooth protocol stack of the watch is deployed on the AP. Any Bluetooth event or message exchange wakes up the AP for processing. A Bluetooth-based service between the watch and mobile phone, for example, synchronizing health and fitness data on the watch to the mobile phone. Although the health and fitness service of the watch is processed through the MCU, the MCU cannot directly interact with the mobile phone through Bluetooth. The AP needs to be woken up for transfer processing. Each Bluetooth service delivery wakes up the AP, causing the AP to wake up frequently. As a result, overall standby time cannot reach an optimal value. Currently, the standby time of the watch in the industry is about two days.

According to the service data transmission method provided in this embodiment of this application, when the MCU meets a processing capability requirement, the service data is directly sent to the MCU without waking up the AP, so that energy consumption of the watch is reduced, and the standby time of the watch is improved.

In the embodiment shown in FIG. 2, the first electronic device is a mobile phone, the second electronic device is the watch, and the watch includes the AP, the MCU, and the Bluetooth chip. Based on the Bluetooth chip of the watch, the mobile phone establishes the first Bluetooth logical channel with the AP and the second Bluetooth logical channel with the MCU. It should be understood that, in another embodiment of this application, the first electronic device and the second electronic device may be other devices (for example, the first electronic device is a tablet computer, and the second electronic device is glasses). The first main control chip and the second main control chip in the second electronic device may be of other types, and a communication chip in the second electronic device may be of another type. Correspondingly, a first logical channel between the first electronic device and the first main control chip and a second logical channel between the first electronic device and the second main control chip may also be of other types.

FIG. 3 is a flowchart of a service data transmission method according to an embodiment of this application. The service data transmission method provided in this embodiment of this application is applied to a first electronic device and a second electronic device, and the second electronic device includes a first main control chip and a second main control chip. The first main control chip is a control chip that has a strong processing capability and high energy consumption, and the second main control chip is a control chip that has a weak processing capability and low energy consumption.

301: The first electronic device establishes a first logical channel with the first main control chip and a second logical channel with the second main control chip.

The first logical channel and the second logical channel are established based on a physical channel (for example, a Bluetooth physical channel) between the first electronic device and the second electronic device.

The first logical channel and the second logical channel may be identified by channel numbers. For example, a channel number of the first logical channel is 5, and a channel number of the second logical channel is 9.

An application scenario shown in FIG. 2 is used as an example. The first electronic device is a mobile phone, the second electronic device is a watch, the first main control chip is an AP, and the second main control chip is an MCU. The mobile phone establishes a first Bluetooth logical channel with the AP and a second Bluetooth logical channel with the MCU.

In an embodiment of this application, the first electronic device establishes the first logical channel with the first main control chip and the second logical channel with the second main control chip in the following manner: The first electronic device establishes a physical channel with the first main control chip, and establishes the first logical channel with the first main control chip, where the first logical channel has a first channel number. The first main control chip generates the second logical channel, where the second logical channel has a second channel number and corresponds to the second main control chip. The first main control chip notifies the first electronic device of the second channel number and the corresponding second main control chip. The first electronic device is connected to the second logical channel based on the second channel number, to establish a connection to the second main control chip.

The application scenario shown in FIG. 2 is still used as an example. The mobile phone establishes the first Bluetooth logical channel with the AP and the second Bluetooth logical channel with the MCU in the following manner: The mobile phone establishes a Bluetooth physical channel with the AP, and establishes the first Bluetooth logical channel with the AP, where the first Bluetooth logical channel has a first Bluetooth channel number. The AP generates the second Bluetooth logical channel, where the second Bluetooth logical channel has a second Bluetooth channel number and corresponds to the MCU. The AP notifies the mobile phone of the second Bluetooth channel number and the corresponding MCU. The mobile phone connects to the second Bluetooth logical channel based on the second Bluetooth channel number, to establish a connection to the MCU.

In an embodiment of this application, the second electronic device includes a communication chip (for example, a Bluetooth chip, as shown in FIG. 2, the communication chip is configured to implement short-range data transmission), and data transmission between the first electronic device and the first main control chip through the first logical channel and data transmission between the first electronic device and the second main control chip through the second logical channel are implemented through the communication chip.

When the first electronic device sends data (for example, service data) to the first main control chip through the first logical channel, the first electronic device may send the first channel number and the data to the communication chip, and the communication chip forwards the data to the first main control chip based on the first channel number. When the first electronic device sends the data to the second main control chip through the second logical channel, the first electronic device may send the second channel number and the data to the communication chip, and the communication chip forwards the data to the second main control chip based on the second channel number.

When the first main control chip sends the data to the first electronic device through the first logical channel, the first main control chip may send the data to the communication chip, and the communication chip sends the data to the first electronic device. When the second main control chip sends the data to the first electronic device through the second logical channel, the second main control chip may send the data to the communication chip, and the communication chip sends the data to the first electronic device.

302: The second main control chip sends an interaction channel policy to the first electronic device through the second logical channel.

The application scenario shown in FIG. 2 is still used as an example. The MCU sends the interaction channel policy to the mobile phone through the second Bluetooth logical channel.

The interaction channel policy is used to describe interaction channels used by different services between the first electronic device and the second electronic device.

In an embodiment of this application, it is defined according to the interaction channel policy that an interaction channel corresponding to a service includes the first logical channel, the second logical channel, and a dynamic logical channel. If the interaction channel corresponding to the service is the first logical channel, it indicates that the service data is transmitted to the first main control chip through the first logical channel. If the interaction channel corresponding to the service is the second logical channel, it indicates that the service data is transmitted to the second main control chip through the second logical channel. If the interaction channel corresponding to the service is the dynamic logic channel, it indicates that the service data is transmitted to the first main control chip through the first logic channel or to the second main control chip through the second logic channel.

FIG. 4 is a schematic diagram of an interaction channel policy between a first electronic device and a second electronic device. FIG. 4 is described by using the application scenario shown in FIG. 2 as an example. As shown in FIG. 4, a distributed collaborative service between the mobile phone and the watch includes a wearable capability (WearEngine), exercise, music, message notification, and the like. An interaction channel corresponding to the wearable capability is the first Bluetooth logical channel, an interaction channel corresponding to the exercise is a dynamic Bluetooth logical channel, an interaction channel corresponding to the music is the first Bluetooth logical channel, an interaction channel corresponding to the message notification is the dynamic Bluetooth logical channel, and an interaction channel corresponding to another service (a service other than the wearable capability, the exercise, the music, or the message notification) is the second Bluetooth logical channel.

FIG. 4 further lists main control chips (a column of a watch processing chip in the figure) corresponding to different services, to indicate the main control chips for processing the service data. For example, a main control chip corresponding to the wearable capability (WearEngine) is the AP, main control chips corresponding to the exercise are the MCU+the AP, a main control chip corresponding to the music is the AP, main control chips corresponding to the message notification are the MCU+the AP, and no corresponding main control chip is specified for the another service.

301 and 302 may be performed after the first electronic device is paired with the second electronic device, to prepare for service data transmission between the first electronic device and the second electronic device.

303: When the service data is to be sent to the second electronic device, the first electronic device determines the interaction channel corresponding to the service.

The application scenario shown in FIG. 2 is still used as an example. When the service data is to be sent to the watch, the mobile phone determines the interaction channel corresponding to the service (which is a service corresponding to the service data).

For example, when a message is to be sent to the watch, the mobile phone determines that the corresponding interaction channel is the dynamic Bluetooth logical channel.

For another example, when music is to be sent to the watch, the mobile phone determines that the corresponding interaction channel is the first Bluetooth logical channel.

304A: If the interaction channel corresponding to the service is the dynamic logical channel, the first electronic device sends a status query instruction to the second main control chip through the second logical channel.

The application scenario shown in FIG. 2 is still used as an example. When the message is to be sent to the watch, the corresponding interaction channel is the dynamic Bluetooth logical channel, and the mobile phone sends the status query instruction to the MCU through the second Bluetooth logical channel.

305: The second main control chip returns status information of the first main control chip and the second main control chip to the first electronic device.

After receiving the status query instruction, the second main control chip queries the status information of the first main control chip and the second main control chip.

The second main control chip may query the status information of the first main control chip through a dual-core service of the second electronic device, and may query the status information of the second main control chip from a status machine of the second main control chip.

The application scenario shown in FIG. 2 is still used as an example. The MCU returns status information of the AP and the MCU to the mobile phone.

In an embodiment of this application, a status of the first main control chip includes a running state and a sleep state, and a status of the second main control chip includes a high-load state and a non-high-load state.

The status information of the first main control chip and the second main control chip that is returned by the second main control chip to the first electronic device may be the statuses of the first main control chip and the second main control chip. Alternatively, the status information of the first main control chip and the second main control chip that is returned by the second main control chip to the first electronic device may be running parameters (for example, processor usage) of the first main control chip and the second main control chip, and the first electronic device determines the statuses of the first main control chip and the second main control chip based on the status information of the first main control chip and the second main control chip.

If the first main control chip is in the running state, it indicates that the first main control chip is processing a service. If the first main control chip is in the sleep state, it indicates that the first main control chip is not processing a service.

If the second main control chip is in the high-load state, it indicates that current load of the second main control chip is heavy. If the second main control chip is in the non-high-load state, it indicates that current load of the second main control chip is light.

Option 1: 306A: If the first main control chip is in the sleep state and the second main control chip is in the non-high-load state, the first electronic device sends the service data to the second main control chip through the second logical channel.

The application scenario shown in FIG. 2 is still used as an example. If the AP is in the sleep state and the MCU is in the non-high-load state, the mobile phone sends the service data to the MCU through the second Bluetooth logical channel.

Option 2: 306B: If the first main control chip is in the running state, the first electronic device sends the service data to the first main control chip through the first logical channel.

The application scenario shown in FIG. 2 is still used as an example. If the AP is in the running state, the first electronic device sends the service data to the AP through the first Bluetooth logical channel.

Option 3: 306C: If the first main control chip is in the sleep state and the second main control chip is in the high-load state, the first electronic device temporarily stores the service data.

The application scenario shown in FIG. 2 is still used as an example. If the AP is in the sleep state and the MCU is in the high-load state, the mobile phone temporarily stores the service data.

304B: If the interaction channel corresponding to the service is the first logical channel, the first electronic device sends the service data to the first main control chip through the first logical channel.

The application scenario shown in FIG. 2 is still used as an example. If the interaction channel corresponding to the service is the first Bluetooth logical channel, the mobile phone sends the service data to the AP through the first Bluetooth logical channel.

For example, the service data to be sent by the mobile phone is music, and the corresponding interaction channel is the first Bluetooth logical channel. The mobile phone sends the music to the AP through the first Bluetooth logical channel.

304C: If the interaction channel corresponding to the service is the second logical channel, the first electronic device sends the service data to the second main control chip through the second logical channel.

The application scenario shown in FIG. 2 is still used as an example. If the interaction channel corresponding to the service is the second Bluetooth logical channel, the mobile phone sends the service data to the MCU through the second Bluetooth logical channel.

For example, the service data to be sent by the mobile phone is the another service, and the corresponding interaction channel is the second Bluetooth logical channel. The mobile phone sends the service data to the MCU through the second Bluetooth logical channel.

It should be noted that, if the interaction channel corresponding to the service is the dynamic logical channel, 304A to 306C are performed; if the interaction channel corresponding to the service is the first logical channel, 304B is performed; and if the interaction channel corresponding to the service is the second logical channel, 304C is performed.

In some embodiments of this application, after the second main control chip receives the service data (may receive the service data through 306, or may receive the service data through 310), the second main control chip determines a service processing policy corresponding to the service data. The second main control chip may determine the service processing policy based on the statuses of the first main control chip and the second main control chip, a user operation on the second electronic device, and the like. The service processing policy may include processing through the first main control chip, processing through the second main control chip, and collaborative processing through the first main control chip and the second main control chip.

In an embodiment of this application, the second main control chip monitors the status of the first main control chip and a quantity of tasks of the second main control chip, and forwards the service data to the first main control chip for processing when detecting that the first main control chip is in the running state, or a quantity of to-be-processed tasks (for example, a quantity of messages in a message buffer pool) of the second main control chip is greater than or equal to a preset quantity (for example, 10).

The application scenario shown in FIG. 2 is still used as an example. After the MCU receives the service data, if the AP is in the running state, the MCU forwards the service data to the AP for processing.

It should be noted that, if the first electronic device sends the service data to the first main control device through the second logical channel, the first main control device directly processes the service, and does not forward the service data to the second main control device for processing.

FIG. 5 is a schematic diagram of a service processing policy of a second main control chip. FIG. 5 is described by using the application scenario shown in FIG. 2 as an example.

Refer to FIG. 5. A service processing policy corresponding to exercise is: An AP performs processing if a user enables a map and an MCU performs processing if another function of the exercise is enabled. To be specific, after the MCU receives service data of the exercise (data such as a pace and a distance), if the user chooses to display a map screen on a watch, the AP performs processing, and the MCU performs processing if another function is enabled.

A service processing policy corresponding to message notification is: Within one minute after a message is received, the user raises the wrist or presses a key to turn on a screen, and the MCU displays the message in full screen. After one minute after the message is received, the user needs to enter a message center of the AP to view the message, and the AP performs processing. In other words, after the MCU receives the message, if the user raises the wrist or presses the key within one minute to turn on the screen, the MCU performs processing and displays the message in full screen. If the user views the message after one minute, the user needs to enter the message center of the AP, and the AP performs processing.

FIG. 6 is a schematic diagram of performing, by a micro control unit of a watch after receiving a message sent by a mobile phone, service processing according to a service processing policy corresponding to a message notification service.

As shown in FIG. 6, after receiving the message sent by the mobile phone, the MCU of the watch determines whether to display the message by an AP or the MCU. Within one minute after the message is received, if a user raises the wrist or presses a key to turn on a screen, the MCU displays the message in full screen and displays a full-screen message display screen. After one minute after the message is received, if the user raises the wrist or presses the key to turn on the screen, the MCU displays a watch face screen. If the user flicks up the watch face screen, the watch enters a message center screen from the watch face screen, and the AP displays the message on the message center screen. When the user performs another flick gesture on the watch face screen, the watch may enter a workout record screen from the watch face screen. When the user presses a key on the watch face screen, the watch may enter a function screen from the watch face screen. When the user does not perform any operation on the full-screen message display screen, the watch face screen, the message center screen, the workout record screen, or the function screen within a timeout limit, the watch screen is turned off.

In a message pushing scenario, the AP does not need to be frequently woken up and running. If the mobile phone pushes 100 messages to the watch every day, standby time of the watch can be increased by 0.4 days.

In an embodiment of this application, when the MCU monitors and detects that the AP is in a running state, or a quantity of messages in a message buffer pool of the MCU is greater than or equal to a preset quantity (for example, 10), the messages are synchronized to the AP (which is shown in the figure and is implemented by using message notification modules of the AP and the MCU).

FIG. 7 is a schematic diagram of performing, by a micro control unit of a watch after receiving a pace and a distance sent by a mobile phone, service processing according to a service processing policy corresponding to an exercise service.

In an embodiment of this application, the mobile phone (for example, a device management application 202 of the mobile phone in FIG. 2) starts the exercise service, and sends an exercise starting notification to the MCU through a second Bluetooth logical channel. After receiving the exercise starting notification, the MCU displays an exercise screen, monitors a user operation, and determines whether the AP or the MCU displays exercise information. In an exercise process, the MCU of the watch sends, to the mobile phone through the second Bluetooth logical channel, data such as a heart rate, blood pressure, and a body temperature that are sensed by the watch, and the mobile phone sends data such as a pace and a distance to the MCU through the second Bluetooth logical channel. A user can view all exercise data on the watch and the mobile phone and control a pause, a resume, and an end of exercise.

As shown in FIG. 7, after receiving the exercise starting notification, the MCU displays the exercise screen. When the user presses a key or flicks on the exercise screen, the AP is woken up and the exercise screen is switched to be displayed through the AP. When the user flicks on the exercise screen displayed by the AP, the AP displays a map screen. When the user presses a key on the map screen to exit, the AP displays an exit confirmation screen. When the user does not perform any operation within a timeout limit, the MCU turns off the screen. When the user raises the wrist or presses a key to turn on the screen, the watch returns to the screen that is displayed before the screen is turned off.

In a connected exercise scenario, standby time of the watch can be increased by 0.2 days based on one-hour exercise per day.

The service data transmission method provided in this application is applied to the first electronic device and the second electronic device that perform the distributed collaborative service. The first electronic device determines a channel for transmitting the service data by the first electronic device to the second electronic device, to reduce a quantity of times of waking up a main control chip with high energy consumption in the second electronic device and improve standby time of the second electronic device.
