Description
Technical Field
The present invention relates to the field of wireless network technologies, and in particular, to a terminal wake-up method and apparatus, and a wireless access device.

When a user accesses a WLAN (Wireless Local Area Network) through an STA (Station), the STA is often required to be not fixed at a specific location, and therefore, the STA is generally a portable electronic device, such as a notebook computer, a tablet computer, a mobile phone, and the like, and the electronic device is powered by a battery to provide a mobile operation function for the user.
In a WLAN networking environment commonly used at present, an STA is connected to an AC (Access Controller) through an AP (Access Point) to Access a WLAN. The power saving of the STA is fully considered, the wireless transmission protocol is specified, after the STA is accessed into the WLAN, if no data flow interaction exists between the STA and the AP within a certain time, the STA can inform the AP that the STA is ready to enter a dormant state by setting a control field in a message sent to the AP, the AP can buffer the data message for the STA, and informs whether the STA buffers the data message or not by sending a beacon frame to the STA, so that the STA can timely receive the data message after the dormant state is ended, and the data message is prevented from being lost.
In order to avoid affecting normal message transmission between the STA and the AP, the STA in the sleep state actively wakes up to monitor a beacon frame sent by the AP every monitoring interval, so as to determine whether to receive a data message, that is, determine whether the AP has the STA to cache the data message, if so, the STA will take out the cached data message, otherwise, the STA will continue to enter the sleep state. Therefore, the STA can frequently switch between sleep and wake-up, and a certain amount of power is consumed in each switching process, but actually, under the condition that most STAs are awakened, the AP does not cache the data packet, so that too much power is consumed by the STA, and the power saving efficiency of the STA is low.

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
First, relevant concepts related to the method provided by the embodiment of the present invention are briefly described.
Beacon frame (Beacon frame): the data frame is a type of a data frame in the WLAN, and is periodically transmitted by the AP, so that the STA discovers the WLAN and determines whether a data packet is cached in the AP.
Silence information element (Quiet IE): an IE (Information Element) defined in the 802.11-2012 protocol (wireless transmission protocol) has an initial effect that when a channel needs to check whether radar interference exists, an AP may send a Beacon frame carrying the IE, where the Beacon frame is sent in a broadcast manner, so that all channels stop data transmission to avoid collision with radar signals. During the silent period, the STA cannot transmit data, and is actually in a sleep state at this time.
Action frame (Action frame): a type of data frame in a WLAN defined in the 802.11-2012 protocol for requiring a STA to take actions carried in the frame.
Preset listening Interval (Listen Interval): when the STA connects to the WLAN and negotiates operating parameters with the AP, the STA calculates a sleep time in units of Beacon intervals (Beacon intervals), where generally, Listen Interval is an integer multiple of Beacon Interval; the STA reports to the AP, namely tells the AP, if the STA enters a sleep state, the STA actively wakes up after every Listen Interval to monitor the Beacon frame. The AP, upon receiving the Listen Interval, stores the value of Listen Interval.
The wireless transmission protocol defines the Power saving mode of the STA, for example, the PS POLL (Power-Save POLL) mode of the 802.11 protocol, the APSD (Automatic Power-Save Delivery) mode of the WMM (Wi-Fi Multimedia ) protocol, the PSMP (Power-Save Multi-POLL) mode of the 802.11n protocol, and the like. In any power saving mode, the STA actively wakes up after each set Listen Interval to monitor the Beacon frame, which results in low power saving efficiency of the STA. In order to improve the power saving efficiency of the STA, embodiments of the present invention provide a terminal wake-up method, apparatus, and wireless access device.
Fig. 1 is a schematic flowchart of a terminal wake-up method according to an embodiment of the present invention, which is applied to a wireless access device, where the wireless access device may be an AC in a WLAN AC + FitAP networking environment or an AP in a fat AP (FATAP) networking environment, and the terminal wake-up method may include the following steps:
s101, if the time length of the STA in the sleep state is determined to be greater than or equal to a first preset time length, determining a silent period, wherein the determined silent period is greater than the acquired monitoring interval of the wireless terminal.
After the STA is connected to the WLAN, if there is a data message, the STA normally interacts the data message according to the original flow, if there is no data message interaction between the wireless access device and the STA continuously, including an uplink message and a downlink message, and after the continuous time reaches a preset time, the wireless access device may determine that the STA enters a sleep state, specifically, the STA may send a message to the wireless access device, the message is provided with a control field Power Management, and the wireless access device determines the subsequent working state of the STA according to the Power Management in the received message:
for example, if the Power Management flag is 1, it indicates that the STA subsequently enters a sleep state, and the wireless access device will buffer the data packet for the STA; if the Power Management flag is 0, it indicates that the STA subsequently enters the awake state, and the wireless access device may directly send the data packet to the STA without buffering.
After the wireless access device determines that the STA enters the sleep state, the duration of the STA in the sleep state is counted, and a measurement unit of the statistics may be Listen Interval, that is, how many Listen intervals pass through the duration. Before the time length that the STA is in the sleep state reaches a first preset time length, the STA may wake up to monitor a Beacon frame issued by the wireless access device according to the set Listen Interval. The Listen Interval may be calculated according to the Beacon Interval of the Beacon frame sent by the wireless access device when the STA is connected to the WLAN and negotiates working parameters with the wireless access device, and is reported to the wireless access device.
If the sleeping time of the STA is greater than or equal to a first preset time, that is, within the first preset time, the STA is always in a sleeping state, and there is no data packet needing to be interacted between the wireless access device and the STA, it is indicated that the data packet needing to be sent to the STA may be cached by the wireless access device for a long time.
S102, when the STA is determined to wake up the monitoring beacon frame and the message sent to the STA is not cached, sending information of a silent period to the STA so as to inform the STA that the time interval of the next time of waking up the monitoring beacon frame is the silent period.
The wireless access device may determine, according to a received message sent by the STA and ready to enter a sleep state or according to a silence period, a time at which the STA wakes up to monitor the Beacon frame, and if the time at which the STA wakes up to monitor the Beacon frame arrives and the message sent to the wireless access device is not cached in the wireless access device, it indicates that there is a low possibility that a data message is cached in a next Listen Interval, and may determine that the STA does not wake up to monitor the Beacon frame in the next Listen Interval, but may wake up to monitor the Beacon frame for a period of time after sleeping for a plurality of times.
Therefore, the wireless access device may send a silent period message to the STA, and notify the STA that the time Interval for waking up to monitor the Beacon frame next time may be the silent period, that is, after a silent period, the STA wakes up to monitor the Beacon frame, instead of waking up to monitor the Beacon frame after a Listen Interval. Because the silent period is greater than Listen Interval, the sleeping time of the STA is prolonged, the awakening times of the STA are reduced, and the electric quantity consumption of the STA is saved. The mode that the wireless access device sends the information of the silent period to the STA can be that the silent period is carried into data frames such as an Action frame, a Probe frame and the like, and the STA identifies the content in the data frames according to a message format specified in a protocol to obtain an accurate silent period, so that the interval for waking up and monitoring the Beacon frame by itself is set. And because the sending modes of the Probe frame and the Action frame are unicast, only the channel of the AP receiving the Probe frame or the Action frame stops data transmission.
By applying the embodiment, when the wireless access device determines that the time length of the STA in the sleep state is greater than or equal to the first preset time length, the wireless access device may determine a silent period greater than the obtained monitoring interval of the STA, and when the STA wakes up to monitor the Beacon frame and the wireless access device does not cache the data packet sent to the STA, send information of the silent period to the STA, that is, inform the STA that the STA does not need to wake up to monitor the Beacon frame in the silent period, and can be in the sleep state all the time until the silent period is ended, so that the sleep time of the STA is prolonged, the power consumption of the STA is saved, and the power saving efficiency of the STA is improved.
Based on the embodiment shown in fig. 1, the wireless access device issues the Beacon frame according to the Beacon Interval to notify the STA whether the data packet to be sent is buffered, so as to ensure real-time data monitoring, that is, the STA may determine that the data packet is buffered in the wireless access device while the wireless access device issues the Beacon frame, and immediately wake up the interaction of the data packet, so that a silence period may be set based on the Listen Interval and the Beacon Interval. As shown in fig. 2, S101 in fig. 1 may specifically include the following steps:
s1011, calculating the product of the Listen Interval of the obtained STA and the Beacon Interval of the transmitted Beacon frame.
S1012, determining the silence period as a preset integer multiple of the product, where the preset integer multiple is greater than or equal to 2.
In order to ensure that the STA wakes up to Listen to the Beacon frame while the wireless access device sends the Beacon frame to the STA, before calculating the silence period, the Listen Interval and the Beacon Interval may be multiplied, and the silence period may be a predetermined integer multiple of the product, that is, the silence period T0 is Listen Interval N Beacon Interval, where N is a predetermined integer multiple greater than or equal to 2.
In a protocol for performing wireless transmission between a wireless access device and an STA, a required time is in the form of an integer multiple of a unit time TU, for example, Beacon Interval is 100TU, and when the Listen Interval is set, the Listen Interval is set to be an integer multiple of the Beacon Interval, for example, the Listen Interval is 10 times the Beacon Interval, so that in order to ensure real-time data monitoring, a silence period may be determined to be 2 times the Listen Interval, that is, 20 times the Beacon Interval, and 1000 times the unit time, and therefore, T0 ═ N ═ Beacon Interval is 1000TU included in information of the silence period.
The preset integral multiple may be obtained by analyzing the past traffic characteristics of the STA, that is, the data packet is cached by the wireless access device only when the STA passes through the Listen Interval. The setting of the preset integral multiple N may be a minimum value or an average value of the number of Listen intervals obtained after the analysis, generally, the preset integral multiple is not taken to be too large, if the preset integral multiple is taken to be too large, the wireless access device may cache too many data packets in a silence period, after the STA wakes up, the wireless access device may need to send many data packets to the STA, which may easily cause a transmission congestion and cause a transmission failure, and therefore, the preset integral multiple N may be set to be 2 or 3.
In view of preventing the data message from being accumulated due to the fact that the first setting is too large, the wireless access device often sets the preset integral multiple shorter, for example, the preset integral multiple is set to be 2 times, when the time length of the STA in the sleep state is determined to be equal to the first preset time length; when the time length of the STA in the sleep state is determined to be longer than the first preset time length, the preset integral multiple is often set to be longer, for example, the preset integral multiple is set to be 3 times.
Based on the embodiment shown in fig. 1, since the issuing mode of the Action frame is unicast, the destination address is the address of the STA, and the format of the query IE is specified in the Action frame, in order to ensure that the wireless access device can accurately notify a certain STA to extend the interval of waking up and monitoring the Beacon frame, the issuing of the information of the silent period can be realized in the form of issuing the Action frame. Therefore, as shown in fig. 3, S102 in fig. 1 may specifically include the following steps:
s1021, the silence period is added to the specified field in the Quiet IE.
S1022, sending the Action frame carrying the Quiet IE to the STA.
Based on the above analysis, it is considered that the Interval for the STA to wake up to Listen to the Beacon frame is extended, and since the Listen Interval is sent by the STA to the wireless access device, the wireless access device cannot actively modify the Listen Interval, and therefore, the wireless access device only informs the STA to wake up after the end of the silence period in a notification manner. The Quiet IE is an IE defined in the wireless transmission protocol, and the wireless access device may send an Action frame carrying the IE, so that the corresponding channel of the STA stops data transmission, that is, the STA cannot send data during a silent period, which may be understood as that the STA is in a sleep state at this time. Based on the definition of the Quiet IE, the silent period of the STA can be set.
An IE is a variable-Length component of a management frame specified in a radio transmission protocol, and generally includes an Element ID number (Element ID) field, a Length (Length) field, and a field whose Length is not fixed. The format of the quick IE is shown in fig. 4, in the quick IE, an Element ID field occupies one byte, i.e., 8 bits; the Length field occupies one byte, namely 8 bits; the Quiet Count field indicates how many Beacon intervals the IE begins to execute, and can be filled with a default value of 0; the Quiet Period field indicates how many Beacon Interval cycles the IE is executed according to, and can be filled with a default value of 0; the Quiet Offset field represents the time Offset of the non-integer Beacon Interval and can be filled with a default value of 0; the Quiet Duration field is the Quiet period of the STA.
The Action frame requires the STA to adopt the Action specified in the frame, so the Action frame can carry a Quiet IE to notify the STA to enter a silent state, that is, the STA can sleep for a silent period after receiving the Action frame and then wake up the monitoring Beacon frame instead of waking up the monitoring Beacon frame according to the previous Listen Interval. The format of the Action frame may be the format specified in the 802.11-2012 protocol, and will not be described herein again. The Action frame is unicast, that is, the Action frame is sent to the STA by the wireless access device in a single direction, and the destination address of the Action frame is the address of the STA.
Assuming that the first preset time duration is 4 times the Listen Interval, the wireless access device may send an Action frame to the STA after the 5 th Listen Interval.
Then, since the last received Action frame carries a silence period, the time for the STA to wake up and monitor the Beacon frame is the time for the STA to wake up and then monitor the Beacon frame again after the last time, for example, the silence period in the Quiet IE of the Action frame is 2 times of the Listen Interval, and the STA wakes up and monitors the Beacon frame after 2 Listen intervals after the last time of wake up.
It should be noted that, in this process, if the STA finds that the data packet is cached in the wireless access device by monitoring the Beacon frame, the step of this embodiment is stopped, and the data packet is transmitted according to the original flow.
In step 101 of the above embodiment, if it is determined that the duration that the STA is in the sleep state is greater than or equal to the first preset duration, the silence period is determined, where the determined silence period may increase with an increase in the duration of the sleep state, specifically:
if the time length of the wireless terminal in the dormant state is determined to be equal to a first preset time length, determining the silent period as a first preset integral multiple of the product of the monitoring interval of the wireless terminal and the beacon interval of the issued beacon frame, wherein the first preset integral multiple is greater than or equal to 2;
and if the duration of the wireless terminal in the dormant state is determined to be greater than the first preset duration, determining the silent period as a second preset integral multiple of the product of the monitoring interval of the wireless terminal and the beacon interval of the issued beacon frame, wherein the second preset integral multiple is greater than the first preset integral multiple.
For example, if the first preset duration is T ═ Listen Interval × 4, after the 5 th Listen Interval, the Beacon frame is sent, and at the same time, the first Action frame is sent to the STA; the silence period carried in the Action frame may be 2 times the Listen Interval; further, when the sleep time is longer than the first preset time, after the 7 th (i.e. 5 Listen Interval + Listen Interval of 2 times of the current silence period) Listen Interval, the Beacon frame is sent, and simultaneously, a second Action frame is sent to the STA; if the silence period in the Action frame is 3 times of Listen Interval, after the 10 th Listen Interval (namely 7 Listen Interval + Listen Interval with the current silence period of 3 times)) is transmitted, the Beacon frame is transmitted, and simultaneously, the third Action frame is transmitted to the STA; and if the silence period in each Action frame is 3 times of Listen Interval, after 3 Listen intervals, sending the Beacon frame and simultaneously sending an Action frame to the STA until the statistical time length is cleared.
Based on the embodiment shown in fig. 1, fig. 5 is a schematic flow chart of a terminal wake-up method provided in another embodiment of the present invention, where the method includes the following steps:
s501, counting the time length of the STA in the sleep state.
S502, judging whether the duration is greater than or equal to a first preset duration, if so, executing S503 to S504, otherwise, executing S505.
S503, determining a silence period greater than the acquired listening interval of the STA.
S504, when it is determined that the STA wakes up the monitoring beacon frame and does not cache the message sent to the STA, sending information of the silent period to the STA to notify the STA that the time interval of waking up the monitoring beacon frame next time is the silent period.
And S505, if the time length of the STA in the sleep state is determined to reach a second preset time length, clearing the time length, and returning to execute S501.
The second preset time period is an upper limit of a set time period for counting the STA in the sleep state, and may be defined according to an actual situation, for example, the preset threshold may be set to 100 Listen intervals, or may be set to be larger, and is not specifically limited herein.
If the time length of the STA in the sleep state is too long, the possibility of data message interaction between the wireless access device and the STA is increased, and if the monitored Beacon frame is awakened according to the silence period, the interaction real-time performance is deteriorated.
When the STA wakes up to monitor the Beacon frame next time, the statistical time does not reach the first preset time, and the information of the silent period cannot be received, so the STA can wake up to monitor the Beacon frame according to the set Listen Interval, and the interaction real-time performance between the wireless access equipment and the STA is improved. If the data message sent to the STA is not cached in the wireless access device when the counted duration reaches the first preset duration again, the silence period may be determined again according to the above steps and sent to the STA.
