Description

Communication equipment and power saving control method and system thereof in Bluetooth communication

Technical Field

The invention relates to the technical field of computer communication, in particular to communication equipment and a power saving control method and system thereof in Bluetooth communication.

Background

The bluetooth technology is an open wireless communication standard, and can be wirelessly connected with digital communication equipment for data transmission in a short distance range, for example, data interaction can be performed between a desktop computer and a notebook computer, a portable device, a PDA, a mobile phone, a camera phone, etc. through bluetooth, or data interaction can be performed between the notebook computer or the mobile phone and a printer, a digital camera, an earphone, a keyboard or a computer mouse through bluetooth, so that a connecting line between the notebook computer or the mobile phone and the printer, the digital camera, the earphone, the keyboard or the computer mouse is omitted, and the bluetooth technology is widely applied.

All devices connected together by bluetooth technology form a piconet network, which may comprise only two devices, such as a laptop and a mobile phone, or multiple devices, which are of the same level after the piconet network is established, but at the beginning of the establishment of the piconet network, one device is a master device and the others are slave devices. The master device or the slave device is provided with a Bluetooth module, so that the master device or the slave device has a Bluetooth function and is used for Bluetooth connection and transmission.

The bluetooth connection process between different devices varies from device to device, but includes two basic processes, namely, establishing a security relationship between devices through pairing between devices, and establishing an application connection.

The Bluetooth function of the device needs to be turned on before the Bluetooth connection is initiated. When attempting to connect devices, the devices should be set to be visible so that they can be discovered by each other. After device pairing is completed, the device may be set to be hidden if there is a concern that the device will be discovered by other devices.

Typically, the master device has a user interface from which most connection settings will be made. One device may be a master device or may act as a slave device to other master devices. For example, when a mobile phone is paired with a wireless headset, the mobile phone is the host. However, when the mobile phone is matched with the notebook computer, the notebook computer is the host.

After devices discover each other, in some cases, a password needs to be entered to complete pairing, for example, the passwords described herein can be divided into two types: one is a designated password, e.g., when paired with a wireless headset, the password is a fixed password designated by the manufacturer for the headset, which the user can find and enter in the user's manual; one is a password set by the user himself. After the password is entered, the devices will authenticate each other and establish a trusted connection. In some cases, verification and connection can be realized between devices without passwords.

After the pairing is completed, information such as the name and address of the other party is acquired, and the information may also be referred to as bluetooth parameters, and at this time, the device has the ability to establish connection.

Then, the master device initiates a connection request of rfcomm to establish the connection of rfcomm, that is, two devices share one rfcomm channel, and data can be transmitted between the two devices.

Current communication devices, such as mobile phones, notebook computers, and the like, are installed with application programs (APPs) for various functions, and when a certain APP is used, there is a need for data transmission with an external bluetooth device (slave device). Because bluetooth consumption is great, after opening bluetooth function, the power consumption of equipment obviously promotes, and to short distance communication's demand, bluetooth provides very big convenience for people again, therefore, the problem that equipment power consumption is big when using bluetooth function has become an actual problem that the industry field will solve.

Detailed Description

In the process of using APP in a communication device, there is usually a need to transmit data through a bluetooth module, and the bluetooth module has large power consumption and relatively high power consumption, and in order to reduce the power consumption of the bluetooth module in the bluetooth communication process, the present invention provides a power saving control method, as shown in fig. 1, which is a schematic flow chart of a power saving control method when the communication device performs bluetooth communication according to the present invention. The power saving control method provided by the invention comprises the following steps:

and step S1a, monitoring the operation state of the APP. The method mainly monitors the life cycle of the APP, and mainly monitors the life cycle of a foreground and the life cycle of a background to determine the running state of the current APP, namely, the APP is monitored to run in the foreground or return to the background. In this step, the foreground lifecycle is monitored.

Regarding monitoring the life cycle of the APP, for example, when the communication device is a smart phone using an iOS system, the method for monitoring the life cycle of the APP includes: the APP may observe the event it entered the foreground and specify the method of response. When the APP enters the foreground, the APP informs the observers, and the observers can respond correspondingly; similarly, the APP can observe the event that the APP falls back to the background, and a corresponding method is specified. In the invention, the response method of entering the foreground is to execute the operation of connecting the Bluetooth; the response method of backing to the background is to execute operations such as Bluetooth disconnection and the like.

If the communication equipment is a smart phone adopting an Android system, the method for the Android system to monitor the life cycle of the APP comprises the following steps: the Application object of the system listens for the lifecycle of Activity. When the number of the foreground Activities is changed from 0 to 1, the APP is shown to enter the foreground from the background, and when the number of the foreground Activities is changed from 1 to 0, the APP is shown to retreat from the foreground to the background.

And step S2a, when the APP foreground life cycle is finished and the background is returned, timing is started. For example, by a built-in software or hardware counter, with a predetermined period, such as several minutes. During the timing, if data transmission between the APP and the Bluetooth device occurs, the timing is stopped, and after the data transmission is finished, the timing is restarted.

Step S3a, when the timing reaches a set timing period, disconnecting the APP from the Bluetooth equipment and storing related Bluetooth parameters;

step S4a, continuing to monitor the running state of the APP;

and S5a, when the APP is changed from the background state to the foreground state, establishing the connection between the APP and the Bluetooth equipment according to the Bluetooth parameters.

Through the method, when the APP needs to use the Bluetooth communication, the connection state of the Bluetooth communication can be ensured, and when the APP does not need to use the Bluetooth communication, the Bluetooth communication connection is disconnected, so that the power consumption of the communication equipment is reduced when the Bluetooth communication connection is maintained, and the purpose of saving power is achieved.

Fig. 2 is a schematic flowchart of a first embodiment of a power saving control method for bluetooth communication of a communication device according to the present invention; in this embodiment, when the APP needs to perform bluetooth transmission, the method specifically includes the following steps:

step S1b, the bluetooth module is turned on.

And step S2b, establishing the connection between the APP and the external Bluetooth device.

The above two steps are similar to the current method of performing bluetooth communication, and a description thereof will not be repeated.

And S3b, monitoring the running state of the APP in the running process of the APP, namely monitoring the foreground life cycle of the APP, finishing the life cycle of the foreground and executing the step S4b when the background is entered.

In step S4b, the timer is started at a set time period.

Step S5b, determining whether the current APP is in data communication with the external bluetooth device, if not, executing step S6b, and if so, executing step S11 b.

And step S6b, judging whether the timing period is reached, if so, executing step 7b, otherwise, returning to step 4b to continue timing.

And S7b, disconnecting the APP from the Bluetooth device and storing the related Bluetooth parameters.

Step S8b, querying whether the communication device running the APP is located in a preset blacklist, if the device running the APP is located in the blacklist, executing step S13b, and if the device running the APP is not located in the blacklist, executing step S9 b.

Step S9b, monitoring the running state of the APP, i.e. monitoring the background lifecycle of the APP, and when the background lifecycle is finished and the foreground is entered, executing step S10 b.

And step S10b, establishing the connection between the APP and the Bluetooth equipment according to the saved Bluetooth parameters. This concludes a control loop.

Step S11b, namely, when data transmission occurs during the timing, data transmission is performed.

Step S12b, judging whether the data transmission is finished, if not, returning to step S11b to continue the data transmission; if the transmission is finished, the process returns to step S4b, and the time counting is started again.

Step S13b, the bluetooth module is turned off.

Step S14b, monitoring the running state of the APP, i.e. monitoring the background lifecycle of the APP, and when the background lifecycle is finished and the foreground is entered, executing step S15 b.

Step S15b, the bluetooth module is turned on, and then step 10b is performed.

In the method flows shown in fig. 1 and fig. 2, the case where the APP falls back to the background includes the case where the user presses the Home key when running the current APP, the device is locked, or the APP exits; the condition that the APP enters the foreground generally includes the condition that the user wakes up the APP, and the interface appearing after the device is unlocked is the current APP or the APP starts.

The bluetooth parameters generally include external bluetooth device names, connection keys, and other parameters required for establishing bluetooth communication connections.

The blacklist shown in fig. 2 refers to a power consumption blacklist, that is, some counted communication devices consuming power relatively, taking a mobile phone as an example, some mobile phone models consuming power relatively are recorded in the power consumption blacklist, and when the blacklist is queried, a query is performed according to the mobile phone model running the APP, so as to determine whether the mobile phone model running the APP is in the blacklist.

Because APP must guarantee when being connected with external bluetooth equipment that bluetooth module is in the open mode, and bluetooth module's opening can accelerate the consumption of cell-phone electric quantity, consequently, the cell-phone of various models is when opening bluetooth module's power consumption of unit time, and the statistical analysis goes out a reasonable demarcation point, lists into the blacklist with its unit time APP's power consumption at the cell-phone above the demarcation point. If the current mobile phone is located in the blacklist, under the premise that the Bluetooth module is opened by the APP, the Bluetooth module is still not used when the APP falls back to the background to reach the set timing period, and then the Bluetooth module is closed, so that the electric quantity of the mobile phone can be greatly saved.
