It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Before introducing the information pushing method, system, and device provided by the embodiment of the present application, a NAN mechanism is briefly introduced first.

In the standard established by the Wi-Fi alliance, channel 6 can be used as the discovery channel in the NAN mechanism, and on the channel 6, the duration of DWs is fixed for each cluster, and the time interval between any two DWs adjacent to the cluster is also fixed.

For example, as shown in fig. 1, fig. 1 is a schematic diagram of a DW of a cluster, and according to a standard established by the Wi-Fi alliance, in the DW, NAN devices in the cluster may send a sync beacon (sync beacon) message in the DW, so that the NAN devices in the cluster maintain synchronization, or may send a Service Discovery Frame (SDF) message for service discovery, and in a time other than the DW, the NAN devices in the cluster may send a discovery beacon (discovery beacon) message to announce the existence of the cluster.

Each NAN device in the cluster may perform service discovery in the DW to discover other NAN devices with which data transmission can be performed. After service discovery, at least two NAN devices which need to perform data transmission with each other can establish a corresponding network with a central node on the appointed time frequency resources according to the appointed network connection mode in the DW according to the appointed time frequency resources and the network connection mode agreed in the DW.

The network established according to the convention may be a basic network of Wi-Fi technology, including an infrastructure basic service set (infrastructure BSS) network, or a peer to peer (P2P) network.

When the at least two NAN devices agree to establish an infrastructure BSS network, if a certain NAN device of the at least two NAN devices is an Access Point (AP), the AP may be used as a central node, and the other NAN devices are all connected to the AP; if the at least two NAN devices are not APs, the user may know that one NAN device is a central node, and the other NAN devices are connected to the NAN device.

When the at least two NAN devices agree to establish the P2P network, the at least two NAN devices may perform a Group Owner (GO) negotiation, determine that a certain NAN device serves as the GO, and use the GO as a central node, where other NAN devices are all connected to the GO.

For example, programs that implement common basic functions on smartphones, such as Short Messaging Service (SMS) SMS, phone dialing, picture viewer, calendar, games, maps, World Wide Web (Web) browser, and other applications developed by developers. The application framework layer provides a series of class libraries required by Android application development, can be used for reusing components, and can also realize personalized extension through inheritance. And the system operation library layer is a support of an application program framework and provides services for each component in the Android system. The system operation library layer is composed of a system class library and Android operation. The Android runtime comprises two parts, namely a core library and a Dalvik virtual machine.

The following describes embodiments of the present application in detail.

Referring to fig. 3, fig. 3 is a schematic flowchart of a NAN scan adjusting method applied to NAN devices, in an embodiment of the present application, where the NAN scan adjusting method includes:

step 301: a NAN device detects a power of the NAN device.

Step 302: the NAN device determines a first scanning strategy when detecting that the current electric quantity of the NAN device is smaller than or equal to a first threshold value.

Step 303: the NAN equipment is adjusted to the first scanning strategy from a current second scanning strategy, the time interval of NAN scanning of the first scanning strategy is larger than that of NAN scanning of the second scanning strategy, and DW of NAN of the first scanning strategy is larger than that of NAN of the second scanning strategy.

The NAN device may include an electronic device, which may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and so on.

The first threshold may be user-defined, or may be self-defined by a NAN device, and is not limited herein.

The NAN device periodically detects the power of the NAN device, and the period may be user-defined or user-defined, which is not limited herein.

Wherein, in case that it is detected that the NAN function is started, the electronic device performs step 301. The NAN function may be started in at least one of the following manners: the method comprises the steps of detecting a click operation aiming at a NAN starting mark, detecting a setting touch operation aiming at a designated position of a display screen of NAN equipment, setting a currently displayed interface of the NAN equipment to be a setting interface or a main interface, detecting a setting gesture and setting the currently displayed interface of the NAN equipment to be the setting interface or the main interface, and detecting a setting click signal and setting the currently displayed interface of the NAN equipment to be the setting interface or the main interface.

The setting touch operation may be user-defined or self-defined by NAN device, and is not limited herein. The setting touch operation includes, for example, a single-click operation, a multi-click operation, a slide operation (e.g., a leftward slide operation, a rightward slide operation, an upward slide operation, a downward slide operation, etc.), a single-click operation followed by a slide operation, a multi-click operation followed by a slide operation, a slide operation followed by a single-click operation, a multi-click operation followed by a slide operation, and the like.

The setting gesture may be user-defined or self-defined by a NAN device, and is not limited herein. Examples of the setting gesture include a ring finger gesture, an OK gesture followed by a ring finger gesture, a ring finger gesture followed by an OK gesture, and the like.

The set tapping signal may be user-defined or self-defined by NAN device, and is not limited herein. The tapping signal includes: at least one of a number of taps, a frequency of taps, and a tapping motion. The knocking action can be one knocking action or a plurality of knocking actions. When the tapping action is a plurality of tapping actions, at least two tapping actions among the plurality of tapping actions are different from each other. The set tapping signal is input by the user according to the set tapping action and the set tapping times in advance. Wherein the set tapping action is a simple tapping action, such as tapping lightly with a finger; or the set tapping action is a more complex tapping action, such as tapping a few times with a first finger and tapping a few times with a second finger.

In an implementation of the present application, before the NAN device determines the first scanning policy, the method further includes:

a NAN device determining that the NAN device is connected with a specific NAN device; the NAN device stops NAN scanning for a first duration.

The specific NAN device may be user-defined or self-defined, and is not limited herein.

Wherein the first duration refers to a period of time after the current system time. The first duration may be user-defined or may be self-defined by a NAN device, and is not limited herein.

It can be seen that, in the embodiment of the present application, when the NAN device has been connected to the characteristic NAN device, the NAN device directly stops the NAN scanning for a period of time, so that power consumption required by the NAN scanning can be saved, and further, the power consumption is reduced.

In an embodiment of the present application, after determining that the NAN device is connected to a specific NAN device, the method further includes:

the NAN device determines that the NAN device keeps connected with the specific NAN device within a second time length, wherein the second time length is greater than or equal to the first time length.

Wherein the second duration refers to a period of time after the current system time.

Further, before the NAN device determines that the NAN device remains connected to the particular NAN device for a second duration, the method further comprises:

popping up a prompt box on a display screen by the NAN equipment, wherein the prompt box is used for prompting a user to input the time length of the NAN equipment which is expected to be connected with the specific NAN equipment; and the NAN equipment receives a second time length input by the user aiming at the prompt box.

Or before the NAN device determines that the NAN device remains connected to the specific NAN device within the second duration, the method further includes:

the NAN equipment acquires a historical connection record of the NAN equipment and the specific NAN equipment, wherein the historical connection record comprises the connection times and the connection duration of each time;

the NAN device determines an average duration of connection of the NAN device with the specific NAN device, and takes the average duration as the second duration.

Or the second duration is set in advance, may be user-defined, or may be self-defined by a NAN device, which is not limited herein.

It can be seen that, in the embodiment of the present application, when the NAN device is already connected to the specific NAN device and the NAN device is connected to the specific NAN device for a period of time, the NAN device directly stops the NAN scanning for a period of time, so that power consumption required by the NAN scanning can be saved, and further, the power consumption is reduced.

In an implementation manner of the present application, before the NAN device determines the first scanning policy, the method further includes:

the NAN equipment determines that an application running in a foreground of the NAN equipment is a first target application; within the third duration, the NAN device stops the NAN scan.

In a NAN network where NAN devices are located, the NAN devices are not central nodes.

The third time period may be equal to the second time period, or may not be equal to the second time period, which is not limited herein.

When the foreground runs the first target application, such as a camera application, a notepad application, a reading application, etc., the NAN device does not need to use the NAN function.

It can be seen that, in the embodiment of the present application, when the first target application is run in the foreground of the NAN device, the NAN device directly stops the NAN scanning for a period of time, so that power consumption required by the NAN scanning can be saved, and further, the power consumption is reduced.

In an implementation manner of the present application, after the NAN device stops the NAN scan, the method further includes:

in a first time length or a third time length, if it is detected that an application running in the foreground of the NAN device is a second target application, the NAN device determines a third scanning strategy, and performs NAN scanning by using the third scanning strategy, wherein a NAN scanning time interval of the third scanning strategy is greater than a NAN scanning time interval of the second scanning strategy, and DW of a NAN of the third scanning strategy is greater than DW of the second scanning strategy.

The NAN device needs to use the NAN function when the foreground runs the second target application, and the first target application is, for example, a shopping application, a payment application, an audio playing application, a video playing application, an instant messaging application, or the like.

The third scanning strategy may be the same as the first scanning strategy or different from the first scanning strategy. When the three scanning strategies are different from the first scanning strategy, the time interval of NAN scanning of the third scanning strategy is smaller than that of NAN scanning of the first scanning strategy, and the DW of the NAN of the third scanning strategy is smaller than that of the NAN of the first scanning strategy.

When the third scanning strategy is different from the first scanning strategy, the specific implementation manner of the NAN device determining the third scanning strategy is as follows: and the NAN equipment determines a third scanning strategy corresponding to the second target application according to the mapping relation between the application and the scanning strategy.

It can be seen that, in this application embodiment, when the second target application is run in the NAN device foreground, it needs the NAN function to indicate the NAN device, and the NAN scan needs to be recovered this moment to guarantee the normal use of the NAN function, and then the intelligence of the device is improved.

In an implementation manner of the present application, after the NAN device adjusts from the current second scanning policy to the first scanning policy, the method further includes:

when the current power of the NAN device is greater than or equal to a second threshold value, or the NAN device is in a charging state and the current power of the NAN device is greater than or equal to the second threshold value, the NAN device is adjusted from the current first scanning policy to the second scanning policy.

The second threshold may be user-defined, or may be self-defined by a NAN device, which is not limited herein. The second threshold is greater than the first threshold.

It can be seen that, in this application embodiment, when the current electric quantity of NAN equipment is sufficient, NAN equipment resumes the NAN scanning strategy to guarantee that the NAN function normally operates, promote the intelligence of equipment.

In an implementation manner of the present application, the specific implementation manner of determining the first scanning policy by the NAN device includes: the NAN device determines a first scanning strategy according to first information, wherein the first information comprises at least one of the following: a current power of the NAN device, a number of currently scanned NAN devices, and a duration of time that the NAN device uses a NAN function.

The duration that the NAN device uses the NAN function refers to a duration that the NAN device expects to use the NAN function. The duration may be preset by the user or the NAN device, or may be preset by the user or the NAN device

Further, the specific implementation manner of determining, by the NAN device according to the first information, the first scanning policy includes: and the NAN equipment determines a first scanning strategy corresponding to the first information according to the mapping relation between the information and the scanning strategy.

For example, the first information includes current electric quantity of the NAN device, and the NAN device determines a first scanning policy corresponding to the current electric quantity of the NAN device according to a mapping relationship between the electric quantity and the scanning policy; for another example, the first information includes the number of currently scanned NAN devices, the NAN devices determine a first scanning policy corresponding to the number of currently scanned NAN devices according to a mapping relationship between the number of NAN devices and the scanning policy, and the like.

It can be seen that, in the embodiment of the present application, the NAN device comprehensively determines the scanning policy, so that the adjusted NAN scanning policy better conforms to the current situation of the NAN device, and the device intelligence is improved.
