When the communication module and/or application module in the device need to enter the sleep state, the communication module and the application module When the communication module and the application module are in the sleep state, the USB interface of the communication module embedded in the device is equivalent to the state of pulling out the device, and no current flows through the USB interface, which saves the battery power of the Internet device .

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

In various embodiments of the present invention, various general input and output (GPIO) indication information are respectively involved. In different cases, the content and form of the GPIO indication information are as follows:

1. The MODULE_SLEEP pin indicates the sleep state of the communication module. The high level of the MODULE_SLEEP pin indicates that the communication module is in the sleep state. The application module can judge the sleep state of the communication module by querying the state of the MODULE_SLEEP pin.

2. The AP_SLEEP pin indicates the sleep state of the application module. The high level of the AP_SLEEP pin indicates that the application module is in the sleep state. The communication module can judge the sleep state of the application module by querying the state of the AP_SLEEP pin.

3. The AP_WAKEUP_MODULE pin is used for the application module to interrupt and wake up the communication module. The high level of the AP_WAKEUP_MODULE pin indicates that the application module wakes up the communication module.

4. The MODULE_WAKEUP_AP pin is used for the interrupt of the communication module to wake up the application module, and the high level of the MODULE_WAKEUP_AP pin indicates that the communication module wakes up the application module.

The foregoing pins are activated at a high level, and the embodiment of the present invention is not limited to activating the foregoing pins at a low level.

In each embodiment of the present invention, AT commands and data are transmitted between the communication module and the application module through the USB interface.

Embodiment one:

As shown in FIG. 1 , it is a schematic diagram of a sleep method of the communication module of the device in Embodiment 1 of the present invention. The method includes the following steps:

Step 101: Determine whether the communication module and/or the application module in the device needs to enter the sleep state from the running state; if so, perform step 102; otherwise, continue to judge whether the communication module and/or the application module need to enter the sleep state.

In this step, the communication module can be a module embedded in the Internet access device for connecting to the wireless communication network, or a module connected to the Internet access device by plugging in and used for connecting to the wireless communication network. Application modules are modules embedded in Internet-connected devices for realizing various business functions.

When the communication module does not transmit data within the set time period, it is considered that the communication module can enter the sleep state. The specific execution method is:

Detect the data transmission between the communication module and the network side and the data transmission between the communication module and the application module, and judge whether there is data transmission between the communication module and the network side or the application module within the set time period; if there is data transmission, It means that the communication module is still in the running state and cannot go to the sleep state; if there is no data transmission, it means that the communication module has not been running within the set time period and can enter the sleep state.

When the application module does not transmit data within the set period of time, it is considered that the application module can enter the sleep state. The specific execution method is as follows:

Detect the data transmitted by the application module. When the application module has no data transmission within the set time period, it is determined that the application module needs to enter the sleep state from the running state; otherwise, it means that the application module is running and cannot enter the sleep state.

The executor of step 101 may be the communication module and/or the application module self-testing whether it needs to enter the sleep state, or other functional modules capable of detecting the data transmission status of the communication module and the application module.

Step 102: Notifying another module of the event of entering the sleep state through GPIO indication information.

When the module entering the sleep state is a communication module, it is necessary to notify the application module in the device of the event that the communication module enters the sleep state. The specific GPIO indication information is: set the MODULE_SLEEP pin to high level. When the MODULE_SLEEP pin of the communication module is set to a high level, the communication module notifies the application module of the event that the MODULE_SLEEP pin is set to a high level through an interrupt. Subsequent application modules can determine the sleep state of the communication module by querying the level state of the MODULE_SLEEP pin of the communication module.

When the module entering the sleep state is an application module, it is necessary to notify the communication module in the device of the event that the application module enters the sleep state. The specific GPIO indication information is: set the AP_SLEEP pin to high level. When the AP_SLEEP pin of the application module is set to a high level, the application module notifies the communication module of the event that the AP_SLEEP pin is set to a high level through an interrupt. The subsequent communication module can determine the sleep state of the application module by querying the level state of the AP_SLEEP pin of the application module.

The execution subject of step 102 can be a communication module and an application module, that is, the communication module controls the level of the MODULE_SLEEP pin through software, and the application module controls the level of the AP_SLEEP pin through software; the execution subject can also be other communication modules that can A functional module that controls the level of the MODULE_SLEEP pin, and a functional module that can control the level of the AP_SLEEP pin of the application module.

Step 103: Disconnect the USB interface between the communication module and the application module.

In this step, there are many ways to disconnect the USB interface between the communication module and the application module, including but not limited to: connecting one of the D+ data lines or D- data lines of the communication module’s USB interface to Power off the pull-up voltage terminal, and disconnect the D+ data line connecting the communication module and the application module, and disconnect the connected D- data line.

Step 104: The modules that need to enter the sleep state enter the sleep state.

Through the solution of Embodiment 1 of the present invention, when the USB interface connection between the communication module and the application module is disconnected, no current will flow through the USB interface, which saves battery power of the Internet access device and prolongs the standby time of the Internet access device.

Various ways of disconnecting the USB interface between the communication module and the application module will be described below through Embodiments 2, 3 and 4.

Embodiment two:

Embodiment 2 of the present invention realizes the purpose of the present invention by powering off the pull-up voltage terminal of the USB interface of the communication module when the communication module needs to enter the sleep state. As shown in Figure 2, the scheme of the second embodiment is as follows:

Step 201: Determine whether the communication module in the device needs to enter the sleep state from the running state, if so, execute step 202; otherwise, continue to judge whether the communication module needs to enter the sleep state.

Step 202: Notify the application module in the device of the event that the communication module enters the sleep state through the GPIO indication information.

Step 203: Power off the pull-up voltage terminal connected to one of the D+ data line or the D- data line of the USB interface of the communication module.

In this step, the transmission rate of the USB interface of the communication module is different, and the data line connected to the pull-up voltage terminal is also different. If the USB interface of the communication module is a high-speed port or a full-speed port, there is a pull-up voltage on the D+ data line; if the USB interface of the communication module is a low-speed port, there is a pull-up voltage on the D- data line.

Because there is a pull-up voltage on one of the D+ data lines or D- data lines of the USB of the communication module, and the other data line is grounded, therefore, when the pull-up voltage terminal is powered off, the D+ data line and D- data line There is no voltage difference between them, therefore, no current flows through the USB interface. At this time, no matter whether the communication module is embedded in the Internet device or not, the USB interface of the communication module is equivalent to pulling out the Internet device, and the communication link of the communication module through the USB interface is disconnected.

The execution subject of step 203 may be the communication module, or other functional modules capable of controlling the voltage of the pull-up voltage terminal connected to the USB interface of the communication module.

Step 204: Power off the USB transceiver (Transceiver) of the communication module.

In this step, on the basis of step 203, the current flowing through the communication module during sleep can be further reduced.

The execution subject of step 204 may be the communication module, or other functional modules capable of controlling the voltage of the USB transceiver of the communication module.

In the first embodiment, the execution order of step 203 and step 204 is not limited, and step 204 may be executed first, and then step 203 may be executed.

Step 205: The communication module enters a sleep state.

In this second embodiment, when the D+ data line of the communication module is connected to the D- data line, there is no current flow, and the USB transceiver of the communication module does not generate current, so the communication module can enter the sleep state, and the USB of the communication module The interface does not generate current, which saves the battery power of the Internet device and prolongs the standby time of the Internet device.

Step 303: Detect whether the communication module has entered the sleep state, if not, execute step 304; otherwise, execute step 305.

When the application module of this embodiment enters the sleep state, the communication module connected to the application module by USB may already be in the sleep state, or it may be in the running state. If the communication module is already in the sleep state according to the method of Embodiment 2, then no current flows through the USB connection, so the application module can also directly enter the sleep state; if the communication module is still in the running state (there is still data transmission between the communication module and the network side) , but there is no data transmission with the application module), the application module notifies the application module of the sleep event through the GPIO indication information, and also needs to request to eliminate the current of the USB connection.

The way to detect the sleep state of the communication module in this step is:

It is judged whether the application module has received the GPIO indication information that the communication module enters the sleep state, if received, the communication module has entered the sleep state; otherwise, the communication module has not entered the sleep state. The GPIO indication information that the communication module enters the sleep state refers to: the MODULE_SLEEP pin is at a high level, that is to say, the application module or other execution subjects query the MODULE_SLEEP pin of the communication module, if the query result is that the MODULE_SLEEP pin is High level means that the communication module has entered the sleep state; otherwise, it means that the communication module has not entered the sleep state.

The execution subject of this step may be an application module, or other functional modules capable of detecting the sleep state of the communication module.

Step 304: Power off the pull-up voltage end of the D+ data line or the D- data line of the USB interface of the communication module.

When the pull-up voltage of the USB interface of the communication module is powered off, the D+ data line and the D- data line connected to the communication module and the application module also have no current flow. At this time, the application module considers that the communication module on the USB interface has been pulled out.

The execution subject of step 304 may be the communication module, or other functional modules capable of controlling the voltage of the pull-up voltage terminal connected to the USB interface of the communication module.

Step 305: Power off the USB transceiver of the application module.

In this step, on the basis of step 305, the current of the USB interface of the communication module and the application module can be further reduced during sleep.

The execution subject of step 305 may be the application module, or other functional modules capable of controlling the voltage of the USB transceiver of the application module.

In the first embodiment, the execution order of step 303 and step 305 is not limited, and step 305 may be executed first, and then step 303 is executed.

Step 306: The application module enters a sleep state.

In the solution of the third embodiment, in the process of the application module entering the sleep state, it is required that the D+ data line of the communication module is connected to the D- data line without current flow, and it is further required that the USB transceiver of the application module does not generate current. Then, after the application module enters the sleep state, the USB interface of the application module and the communication module will not generate current, which saves the battery power of the Internet device and prolongs the standby time of the Internet device.

It should be noted that the solutions of Embodiment 2 and Embodiment 3 of the present invention can be combined together to perform the sleep process of the application module and the communication module of the device at the same time.

A switch (USB_ON) is set between the D+ data line of the application module, and the disconnection and connection between the D+ data line of the communication module and the application module are realized through the high and low voltage of USB_ON; and, the D- of the communication module and the application module A switch (USB_ON) is also set between the data lines, and the disconnection and connection between the D-data lines of the communication module and the application module are realized through the high and low voltages of USB_ON.

Step 403: Disconnect the D+ data line and the D- data line connecting the communication module and the application module.

When the D+ data line and D- data line connected to the communication module and the application module are disconnected, the application module generates a USB interface pull event at this time, so that the communication module embedded in the Internet device and the application module are disconnected during sleep. , to achieve the purpose of reducing the standby current.

The execution subject of this step is a functional module capable of controlling the voltage of USB_ON.

Step 404: Power off the USB transceiver of the module that needs to enter the sleep state.

Step 405: The module that needs to enter the sleep state enters the sleep state.

In the solution of Embodiment 4, when the application module or the communication module enters the sleep state, the D+ data line and the D- data line between the communication module and the application module are required to be disconnected, so that there is no current flow on the data line. It is further required that the USB transceivers of the application module and the communication module do not generate current. After the application module enters the sleep state, the USB interface of the application module and the communication module will not generate current, which saves the battery power of the Internet device and prolongs the life of the Internet device. standby time.
