Description

A method and terminal for monitoring beacon frames

technical field

The invention relates to the field of communication technology, in particular to a method and terminal for monitoring beacon frames.

Background technique

WIFI (Wireless Fidelity, wireless fidelity) is a technology that can connect a terminal device to a wireless local area network in a wireless manner. With the development of WIFI technology, WIFI hotspots can be seen everywhere, such as shopping malls, homes and office buildings, etc., bringing great convenience to people's work and life. At the same time, people put forward higher requirements on the connection stability and data transmission efficiency of WIFI.

At present, the WIFI technology mainly transmits data by sending Beacon (beacon) frames through the access point. When the terminal device is in the standby state, the access point sends a beacon frame every Beacon-Interval (beacon interval). Each beacon frame contains transmission indication information (TIM, TrafficIndication Message) for notifying the associated terminal equipment whether there is a buffer information bit, and the beacon frame of each fixed period contains a message for notifying the existence of multicast data buffer information Delivery Traffic Indication Message (DTIM, Delivery Traffic Indication Message). The terminal device receives the beacon frame at an integer multiple of the Beacon-Interval as the monitoring interval, and decodes the buffer information bits in it to determine whether there is data buffered. However, when the signal is weak or the channel quality is poor, a long monitoring interval may cause the terminal connection to be disconnected, so that data cannot be received in time.

It can be seen that if the beacon frame is received according to the existing monitoring interval, the stability of the data connection is poor.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a flowchart of a method for listening to a beacon frame provided by an embodiment of the present invention. The method is applied to a terminal, as shown in FIG. 1, and includes the following steps:

Step 101. Obtain the beacon interval of the access point, the cycle of transmitting service indication information, and network environment parameters.

Optionally, in this step, the network environment parameters include at least one of data traffic, signal strength, and channel quality.

This step can be performed when the terminal is in a dormant state. In this state, the terminal can store all running real-time data on the hard disk, and turn off all unnecessary hardware to save power. The above access point may be an access point associated with the terminal. When the terminal is successfully associated with the access point, data transmission can be performed between the terminal and the access point. In this way, the beacon of the access point can be obtained through the beacon frame Interval and delivery cycle of service indication information.

As shown in FIG. 2, access point A sends beacon frame 1 every beacon interval T1, and terminal B receives beacon frame 1 every listening interval. Beacon frame 1 at a fixed period contains delivery service indication information 2 for notifying the existence of multicast data buffer information, and this fixed period may be referred to as delivery service indication information period T2. For example, as shown in FIG. 2 , if T2 is 3, then the information of three beacon frames includes the indication information of one delivery service.

The foregoing network environment parameters may be understood as parameters that affect network connection stability or data receiving efficiency. Specifically, the network environment parameter may be any one of data traffic, signal strength, and channel quality or any combination of data traffic, signal strength, and channel quality. For example, the network environment parameters include signal strength and channel quality; in another example, the network environment parameters include data traffic, signal strength, and channel quality.

The terminal can obtain the value or average value of the network environment parameter within a preset time. For example, obtain the data traffic within 1 second, and use this traffic as the data traffic of the network; another example, obtain multiple values of the signal strength of the network within 5 seconds, and obtain the average value of multiple values, and use the average value as The signal strength value of the network.

Step 102: Determine a beacon frame listening interval according to the network environment parameters, the beacon interval, and the delivery service indication information cycle.

In this step, the terminal may calculate the obtained network environment parameter values, beacon interval and service indication information transmission period according to a preset method, and use the calculation result as the listening interval of the beacon frame. In this way, when the network environment changes, the monitoring interval can be changed accordingly, so that the monitoring interval can adapt to the network environment, thereby improving the stability of the network connection and the efficiency of data reception.

Step 103, monitor beacon frames according to the monitoring interval.

In this step, the terminal monitors the beacon frame every the above-mentioned listening interval. In this way, when the network environment changes, the calculated listening interval also changes accordingly until the terminal is disconnected from the access point.

In the embodiment of the present invention, the above-mentioned method for listening to beacon frames can be applied to terminals, such as: computers, servers, mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop Computer), personal digital assistants (personal digital assistant) , referred to as PDA), mobile Internet device (Mobile Internet Device, MID) or wearable device (Wearable Device) and so on.

The method for listening to beacon frames in the embodiment of the present invention obtains the beacon interval of the access point, the period of the delivery service indication information, and the network environment parameters; according to the network environment parameters, the beacon interval and the delivery service indication The information period determines the monitoring interval of the beacon frame; according to the monitoring interval, the beacon frame is monitored. In this way, when the network environment changes, the terminal can adjust the monitoring interval of the beacon frame according to the network environment parameters, thereby improving the stability of the data connection and reducing the power consumption of the terminal.

Referring to FIG. 3 , the main difference between this embodiment and the foregoing embodiments is that the monitoring interval of the beacon frame is determined according to the level of the network environment parameter. Fig. 3 is a flowchart of a method for listening to a beacon frame provided by an embodiment of the present invention, as shown in Fig. 3 , including the following steps:

Step 301. Obtain the beacon interval of the access point, the period for transmitting service indication information, and network environment parameters.

This step can be performed when the terminal is in a dormant state. In this state, the terminal can store all running real-time data on the hard disk, and turn off all unnecessary hardware to save power. The above access point may be an access point associated with the terminal. When the terminal is successfully associated with the access point, data transmission can be performed between the terminal and the access point. In this way, the beacon of the access point can be obtained through the beacon frame Interval and delivery cycle of service indication information.

As shown in FIG. 2, access point A sends beacon frame 1 every beacon interval T1, and terminal B receives beacon frame 1 every listening interval. Beacon frame 1 at a fixed period contains delivery service indication information 2 for notifying the existence of multicast data buffer information, and this fixed period may be referred to as delivery service indication information period T2. For example, as shown in FIG. 2 , if T2 is 3, then the information of three beacon frames includes the indication information of one delivery service.

The foregoing network environment parameters may be understood as parameters that affect network connection stability or data receiving efficiency. For example, signal strength, channel quality, data traffic size, etc.

The terminal can obtain the value or average value of the network environment parameter within a preset time. For example, obtain the data traffic within 2 seconds, and use this traffic as the data traffic of the network; another example, obtain multiple values of the signal strength of the network within 5 seconds, and obtain the average value of multiple values, and use the average value as The signal strength value of the network. This is just an example.

Step 302. Obtain a target parameter level of the network environment parameter in preset network environment parameter levels.

Optionally, in this step, the network environment parameters include data traffic, signal strength and channel quality, the first target level of the data traffic of the network where the terminal is located is obtained among the preset traffic levels, and the network environment parameters where the terminal is located are obtained. The signal strength of the network is at the second target level among the preset signal levels, and the channel quality of the network where the terminal is located is at the third target level among the preset channel levels.

Before this step, the network environment parameters may be divided into multiple levels in advance, and the multiple levels and the parameter ranges corresponding to the multiple levels are stored in the terminal. When acquiring the network environment parameter, the target level of the network environment parameter in the preset network environment parameter level may be determined according to the pre-divided network environment parameter level. When the network environment is good, the network environment parameters can be set at a higher level; when the network environment is poor, the network environment parameters can be set at a lower level.

Specifically, multiple levels of data traffic, signal strength, and channel quality and the parameter ranges corresponding to the multiple levels can be set respectively, and the terminal can set the level according to the impact of network environment parameters on the network environment. For example, when the signal strength of the network is stronger, it means that the network environment is better, and the level of signal strength can be set higher; when the signal strength is weaker, it means that the network environment is poor, and the level of signal strength can be set lower. For another example, when the data traffic is less, it means that the network environment is better, and the level of data traffic can be set higher; when the data traffic is larger, it means that the network environment is poor, and the level of data traffic can be set lower.

When acquiring network data traffic values, signal strength values, and channel quality values that can indicate channel quality, the first target level where the data traffic value is located and the first target level where the signal strength value is located can be determined according to the preset level and parameter range. The second target level, and the third target level where the channel quality value is located.

For example, set the data flow range from 0k to 100k as the third level; set the data flow range from 100k to 200k as the second level; set the data flow range from 200k to 300k as the first level. When the acquired data traffic is 50k, the level of the data traffic is determined to be 3.

The foregoing data traffic value, signal strength value, and channel quality value may be values acquired within a preset time, or may be an average value of multiple values acquired within a preset time.

In this embodiment, the target level of the network data traffic, signal strength, and channel quality among the preset levels is acquired. In this way, when the network environment is good, the higher the target level is, the monitoring interval can be extended to achieve the beneficial effect of reducing the power consumption of the terminal; when the network environment is poor, the lower the target level is, so that the monitoring interval can be shortened , to achieve the beneficial effect of improving the stability of the network connection.

Step 303 : Determine a beacon frame monitoring interval according to the target parameter level, the beacon interval, and the delivery service indication information period.

Optionally, in this step, a first product of the first target level, the second target level, the third target level, the beacon interval and the period of delivering service indication information is obtained;

judging whether the first product is greater than a preset value;

If the first product is less than or equal to the preset value, the first product is used as the listening interval of the beacon frame.

The terminal may use the acquired target parameter level of the network environment, the beacon interval, and the period for transmitting service indication information calculated in a preset manner as the listening interval of the beacon frame.

Specifically, the terminal may calculate the product of the first target level, the second target level, the third target level, the beacon interval, and the period for delivering service indication information, and judge whether the product is greater than the upper limit value of the preset listening interval, that is, default value. Specifically, it can be calculated as follows:

L1=BI1×DTIM1×Fn×Rn×Qn

Among them, L1 is the calculated value of the first product, BI1 is the beacon interval, DTIM1 is the period of transmitting service indication information, Fn is the first target level, Rn is the second target level, and Qn is the third target level.

Assuming that the beacon interval is k, and the cycle of transmitting service indication information is 3, when the first target level is 2, the second target level is 1, and the third target level is 1, the calculated first product is k×3×2× 1×1=6k.

When the calculated value of the first product is less than or equal to the preset value, the calculated value of the first product is used as the monitoring interval.

In this embodiment, the listening interval is calculated according to the network environment parameters, so that when the network environment changes, the listening interval can be changed accordingly, so that the listening interval can adapt to the network environment. When the network environment is good, the higher the target parameter level is, the monitoring interval can be extended, thereby reducing the power consumption of the terminal; when the network environment is poor, the lower the target parameter level is, the monitoring interval can be shortened, thereby improving The stability of the network connection.

Optionally, after the step of judging whether the first product is greater than a preset value, the method further includes:

If the first product is greater than the preset value, obtain the second product of the beacon interval and the delivery service indication information period, calculate the ratio of the preset value to the second product, and follow the Carry out rounding to the described ratio in the way of rounding down to obtain the rounded value;

A third product of the second product and the rounded value is used as the listening interval of the beacon frame.

In this embodiment, when the calculated first product is greater than a preset value, the monitoring interval may be recalculated. Specifically, the following calculation formula can be used for calculation:

L2=LI1×[L3/LI1], LI1=BI1×DTIM1, where L2 is the listening interval, LI1 is the second product, L3 is the preset value, BI1 is the beacon interval, and DTIM1 is the cycle for delivering service indication information.

It should be noted that after the ratio of L3 to LI1 is calculated, the ratio is rounded down to obtain a rounded value, and then the rounded value is multiplied by LI1 to obtain the third product. For example, L3 is 8, LI1 is 3, then L2=3×(8/3)=3×2=6.

In this way, when the calculated first product exceeds the preset value, the second product of the beacon interval and the delivery service indication information period is obtained, the ratio of the preset value to the second product is calculated, and according to The ratio is rounded down to obtain a rounded value; the third product of the second product and the rounded value is used as the listening interval of the beacon frame, so that the beacon The monitoring interval of the frame is within a certain range, so as to ensure the stability of the data connection.

Step 304, monitor beacon frames according to the monitoring interval.

In this step, the terminal monitors the beacon frame every the above-mentioned listening interval. When the network environment changes, the calculated listening interval also changes until the terminal is disconnected from the access point.

The method for listening to beacon frames in the embodiment of the present invention determines the listening interval of beacon frames according to the target parameter level where the network environment parameters are located, the beacon interval, and the cycle of transmitting service indication information. In this way, when the network environment changes, the listening interval can be changed accordingly, so that the listening interval can adapt to the network environment. When the network environment is good, the monitoring interval can be extended, thereby reducing the power consumption of the terminal; when the network environment is poor, the monitoring interval can be shortened, thereby improving the stability of the network connection.
