Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for monitoring a beacon frame.
Background
WIFI (Wireless Fidelity) is a technology that can wirelessly access a terminal device to a Wireless local area network. With the development of the WIFI technology, the WIFI hotspots are visible everywhere, for example, in shopping malls, homes, office buildings and the like, which brings great convenience to the work and life of people. Meanwhile, people put forward higher requirements on the connection stability of WIFI, the data transmission efficiency and the like.
At present, the WIFI technology mainly transmits Beacon (Beacon) frames through an access point for data transmission. When the terminal device is in a standby state, the access point transmits a Beacon frame every Beacon-Interval. Each beacon frame includes transmission Indication information (TIM) for notifying the associated terminal device of the presence of a cache information bit, and every other beacon frame includes Delivery Traffic Indication information (DTIM) for notifying the presence of multicast data cache information. The terminal equipment receives the Beacon frame by taking the integral multiple of Beacon-Interval as a monitoring Interval, and decodes the cache information bit in the Beacon frame to determine whether data is cached or not. However, when the signal is weak or the channel quality is poor, the long listening interval may cause the terminal connection to be disconnected, so that data cannot be received in time.
It can be seen that receiving the beacon frame according to the existing listening interval results in poor stability of the data connection.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for listening for a beacon frame according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 1, the method includes the following steps:
Optionally, in this step, the network environment parameter includes at least one of data traffic, signal strength, and channel quality.
This step may be performed while the terminal is in a sleep state. In this state, the terminal can store all running real-time data onto the hard disk and turn off all unnecessary hardware to save power. The access point may be an access point associated with the terminal, and when the association between the terminal and the access point is successful, data transmission may be performed between the terminal and the access point, so that a beacon interval of the access point and a period of transmitting the service indication information may be obtained through a beacon frame.
As shown in fig. 2, the access point a transmits a beacon frame 1 every beacon interval T1, and the terminal B receives the beacon frame 1 every listening interval. The beacon frame 1 at every fixed period includes the delivery service indication information 2 for notifying the existence of the multicast data cache information, and the fixed period may be referred to as a delivery service indication information period T2. For example, as shown in fig. 2, T2 is 3, and three pieces of beacon frame information include once-delivered traffic indication information.
The above-mentioned network environment parameter may be understood as a parameter that affects network connection stability or data reception efficiency, etc. Specifically, the network environment parameter may be any one of or any combination of data traffic, signal strength, and channel quality. For example, network environment parameters include signal strength and channel quality; as another example, network environment parameters include data traffic, signal strength, and channel quality.
The terminal may acquire a value or an average value of the network environment parameter within a preset time. For example, data traffic within 1 second is acquired, and the traffic is taken as data traffic of the network; for another example, a plurality of values of the signal strength of the network within 5 seconds are obtained, and an average value of the plurality of values is obtained as the signal strength value of the network.
And step 102, determining a monitoring interval of a beacon frame according to the network environment parameter, the beacon interval and the transmission service indication information period.
In this step, the terminal may calculate the obtained values of the network environment parameters, the beacon interval, and the period of the transmission service indication information according to a preset manner, and then use the calculation result as the monitoring interval of the beacon frame. Therefore, when the network environment changes, the monitoring interval can correspondingly change, so that the monitoring interval is adaptive to the network environment, and the stability of network connection and the efficiency of data receiving are improved.
And 103, monitoring the beacon frame according to the monitoring interval.
In this step, the terminal listens for beacon frames at every listening interval. Thus, when the network environment changes, the calculated listening interval also changes until the terminal disconnects from the access point.
In this embodiment of the present invention, the method for monitoring a beacon frame may be applied to a terminal, for example: a Computer, a server, a Mobile phone, a Tablet Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The method for monitoring the beacon frame of the embodiment of the invention obtains the beacon interval of the access point, the period of transmitting the service indication information and the network environment parameters; determining a monitoring interval of a beacon frame according to the network environment parameter, the beacon interval and the transmission service indication information period; and monitoring the beacon frame according to the monitoring interval. Therefore, when the network environment changes, the terminal can adjust the monitoring interval of the beacon frame according to the network environment parameters, so that the stability of data connection can be improved, and the power consumption of the terminal can be reduced.
Referring to fig. 3, the present embodiment is mainly different from the above-described embodiments in that the listening 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 for a beacon frame according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
This step may be performed while the terminal is in a sleep state, in which the terminal may store all running real-time data onto the hard disk and turn off all unnecessary hardware to save power. The access point may be an access point associated with the terminal, and when the association between the terminal and the access point is successful, data transmission may be performed between the terminal and the access point, so that a beacon interval of the access point and a period of transmitting the service indication information may be obtained through a beacon frame.
As shown in fig. 2, the access point a transmits a beacon frame 1 every beacon interval T1, and the terminal B receives the beacon frame 1 every listening interval. The beacon frame 1 at every fixed period includes the delivery service indication information 2 for notifying the existence of the multicast data cache information, and the fixed period may be referred to as a delivery service indication information period T2. For example, as shown in fig. 2, T2 is 3, and three pieces of beacon frame information include once-delivered traffic indication information.
The above-mentioned network environment parameter may be understood as a parameter that affects network connection stability or data reception efficiency, etc. Such as signal strength, channel quality, data traffic size, etc.
The terminal may acquire a value or an average value of the network environment parameter within a preset time. For example, data traffic within 2 seconds is acquired, and the traffic is taken as data traffic of the network; for another example, a plurality of values of the signal strength of the network within 5 seconds are obtained, and an average value of the plurality of values is obtained as the signal strength value of the network. This is by way of example only.
Optionally, in this step, the network environment parameters include data traffic, signal strength, and channel quality, a first target level of the data traffic of the network where the terminal is located in a preset traffic level is obtained, a second target level of the signal strength of the network where the terminal is located in a preset signal level is obtained, and a third target level of the channel quality of the network where the terminal is located in a preset channel level is obtained.
Before this step, the network environment parameters may be divided into a plurality of levels in advance, and parameter ranges corresponding to the plurality of levels and the plurality of levels respectively may be stored in the terminal. When the network environment parameter is obtained, the target level of the network environment parameter in the preset network environment parameter level can be determined according to the pre-divided network environment parameter level. When the network environment is better, the level of the network environment parameter can be set to be higher; when the network environment is poor, the level at which the network environment parameter is located may be set to be low.
Specifically, multiple levels of data traffic, signal strength, and channel quality and parameter ranges corresponding to the multiple levels may be set, respectively, and the terminal may set the level according to the influence of the network environment parameters on the network environment. For example, when the signal strength of the network is stronger, which indicates that the network environment is better, the level of the signal strength may be set to be higher; when the signal strength is weaker, indicating that the network environment is poor, the level of the signal strength may be set lower. For another example, when the data traffic is less, it indicates that the network environment is better, and the level of the data traffic can be set to be higher; when the data traffic is larger, the network environment is poor, and the level of the data traffic can be set to be lower.
When the data traffic value, the signal strength value and the channel quality value which can represent that the channel quality is good or bad of the network are obtained, a first target grade where the data traffic value is located, a second target grade where the signal strength value is located and a third target grade where the channel quality value is located can be determined according to preset grades and parameter ranges.
For example, a data traffic range of 0k to 100k is set as the third level; setting the data flow range of 100k to 200k as a second level; the data traffic range of 200k to 300k is set as the first level. When the acquired data traffic is 50k, the rank of the data traffic is determined to be 3.
The data traffic value, the signal strength value, and the channel quality value may be obtained values within a preset time, or may be an average value of a plurality of values obtained within the preset time.
In this embodiment, target levels of data traffic, signal strength, and channel quality of the network among the preset levels are obtained. Therefore, when the network environment is better, the obtained target level is higher, so that the monitoring interval can be prolonged, and the beneficial effect of reducing the power consumption of the terminal is achieved; when the network environment is poor, the obtained target level is lower, so that the monitoring interval can be shortened, and the beneficial effect of improving the stability of network connection is achieved.
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 transmitting the service indication information is obtained;
judging whether the first product is larger than a preset value or not;
and if the first product is smaller than or equal to the preset value, taking the first product as the monitoring interval of the beacon frame.
The terminal may use a calculation result obtained after the target parameter level where the network environment is located, the beacon interval, and the period of the transmission service indication information are calculated according to a preset manner as the monitoring interval of the beacon frame.
Specifically, the terminal may calculate a product of the first target level, the second target level, the third target level, the beacon interval, and the period of transmitting the traffic indication information, and determine whether the product is greater than an upper limit value, i.e., a preset value, of a preset listening interval. Specifically, the calculation can be performed as follows:
L1＝BI1×DTIM1×Fn×Rn×Qn
wherein, L1 is a calculated value of the first product, BI1 is a beacon interval, DTIM1 is a period for transferring traffic indication information, Fn is a first target level, Rn is a second target level, and Qn is a third target level.
Assuming that the beacon interval is k and the period for transferring the traffic 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 first product calculated is k × 3 × 2 × 1 × 1 — 6 k.
And when the calculated value of the first product is smaller than or equal to the preset value, taking the calculated value of the first product 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 may change accordingly, so that the listening interval is adapted to the network environment. When the network environment is better, the higher the grade of the obtained target parameter is, the monitoring interval can be prolonged, so that the power consumption of the terminal can be reduced; when the network environment is poor, the lower the level of the acquired target parameter is, the shorter the monitoring interval can be, so that the stability of network connection can be improved.
Optionally, after the step of determining whether the first product is greater than a preset value, the method further includes:
if the first product is larger than the preset value, acquiring a second product of the beacon interval and the period of the service transmission indication information, calculating a ratio of the preset value to the second product, and rounding the ratio in a downward rounding mode to obtain a rounded value;
and taking a third product of the second product and the rounded value as a monitoring interval of the beacon frame.
In this embodiment, the listening interval may be recalculated when the calculated first product is greater than a preset value. Specifically, the following calculation formula can be adopted 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 delivery traffic indication information period.
It should be noted that after calculating the ratio of L3 to LI1, the ratio is rounded down to obtain a rounded value, and the rounded value is multiplied by LI1 to obtain a third product. For example, if L3 is 8 and LI1 is 3, then L2 is 3 × (8/3) is 3 × 2 is 6.
Thus, when the calculated first product exceeds a preset value, a second product of the beacon interval and the period of transmitting the service indication information is obtained, the ratio of the preset value to the second product is calculated, and the ratio is rounded in a downward rounding mode to obtain a rounded value; and taking the third product of the second product and the rounded value as the monitoring interval of the beacon frame, so that the monitoring interval of the beacon frame is in a certain range, and the stability of data connection is ensured.
And step 304, monitoring the beacon frame according to the monitoring interval.
In this step, the terminal listens for beacon frames at every 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 monitoring the beacon frame of the embodiment of the invention determines the monitoring interval of the beacon frame according to the target parameter level of the network environment parameter, the beacon interval and the period of the transmission service indication information. Thus, when the network environment changes, the listening interval can change correspondingly, so that the listening interval is adapted to the network environment. When the network environment is good, the monitoring interval can be prolonged, so that the power consumption of the terminal can be reduced; when the network environment is poor, the listening interval can be shortened, so that the stability of network connection can be improved.
