The TDLS connection is two STAs connected to the same AP (access point), and a TDLS direct link may be established. Therefore, the two STA communication does not need to be forwarded through the AP, and can be directly communicated. And the two STA devices may switch to another channel for communication as needed.

Detailed Description
As described in the background art, there is a problem in the prior art how to accurately determine the timing of channel switching under TDLS connection, so as to obtain better transmission efficiency.
To solve the above problem, an embodiment of the present invention provides a method for switching STA channels under TDLS connection, including: when the first STA judges that the busyness of the current channel exceeds a threshold value, one or more alternative channels are measured respectively; selecting a target channel to be switched from the one or more alternative channels; switching to the target channel, and sending a switching notification to a second STA so that the second STA is switched to the target channel; wherein the first STA and the second STA establish a TDLS connection.
Therefore, the time for switching the channels under the TDLS connection can be accurately judged so as to obtain better transmission efficiency.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for STA channel switching under TDLS connection, where the method is executed by a first STA side, and the method includes:
step S101, when the first STA judges that the busyness of the current channel exceeds a threshold value, one or more alternative channels are respectively measured;
after the 2 STAs establish TDLS communication, one STA is referred to as a first STA, another STA is referred to as a second STA, a Channel (Channel) in which the 2 STAs are currently located is referred to as a current Channel, and other channels which can be used for the 2 STAs to communicate except the current Channel are referred to as alternative channels.
The busyness is used to characterize the data transmission efficiency of the current channel to determine whether a channel switch needs to be performed. The threshold is a preset busy threshold for determining that channel switching needs to be executed.
Optionally, whether the busyness of the current channel exceeds a threshold may be determined according to the idle ratio of the current channel and/or the channel utilization rate; the idle ratio of the current channel is a ratio of the idle time of the current channel to the preset time within the preset time, and the channel utilization ratio is a ratio of the transceiving time of the first STA to the preset time within the preset time.
Namely, the busy degree of the current channel is obtained according to the idle ratio and/or the channel utilization rate of the current channel.
The idle ratio of the current channel = clear _ mib _ cnt/total _ mib _ cnt, where clear _ mib _ cnt is an idle time of the current channel within a preset time, and total _ mib _ cnt is a preset time.
The channel utilization ratio = TR _ mib _ cnt/total _ mib _ cnt, where TR _ mib _ cnt is a transceiving time of the first STA within a preset time.
Optionally, the transceiving time of the first STA is a sum of a packet sending time total and a packet receiving time total of the first STA, and the packet receiving time total is a sum of times of receiving a unicast packet and a broadcast multicast packet.
That is, TR _ mib _ cnt = tx _ mib _ cnt + rx _ mib _ cnt, where tx _ mib _ cnt is a total amount of packet sending time of the first STA within a preset time, and rx _ mib _ cnt is a total amount of packet receiving time of the first STA within the preset time. The packet reception action of the first STA includes receiving a unicast packet for itself and receiving a broadcast multicast packet.
Optionally, a timer may be started at the first STA side to time the preset time, the transceiving time, and the idle time of the current channel, and the busyness of the current channel in the preset time is calculated.
Step S102, selecting a target channel to be switched from the one or more alternative channels;
when it is determined that channel switching needs to be performed, the signal quality and the like of each candidate channel are measured to acquire the state of each candidate signal, and whether it is appropriate to be a target channel is determined. The first STA selects a target channel according to the measurement result of each candidate channel in step S101, where the target channel is a channel to which the 2 STAs are to be switched.
Step S103, switching to the target channel, and sending a switching notification to a second STA, so that the second STA is switched to the target channel; wherein the first STA and the second STA establish a TDLS connection.
After the first STA determines the target channel, the first STA informs the second STA to perform a handover, and the first STA also switches to the target channel, so that the 2 STAs complete channel switching and can continue TDLS communication in the target channel.
In this embodiment, a channel switching mechanism under TDLS connection is provided, by which the busyness of the current channel can be determined, and an optimal channel is selected for switching by measuring the remaining channels. Thus, better transmission efficiency can be obtained, so as to obtain better channel utilization rate and communication effect.
In an embodiment, please refer to fig. 2, fig. 2 is a schematic flowchart of a specific implementation manner of step S101 in fig. 1, where the determining whether the busy level of the current channel exceeds the threshold according to the idle ratio and/or the channel utilization ratio of the current channel specifically includes the following steps:
step S201, obtaining the idle proportion and the channel utilization ratio of the current channel in a plurality of continuous monitoring periods;
step S202, averaging the idle ratios of a plurality of monitoring periods to be used as the idle ratio of the current channel;
step S203, averaging the channel utilization rates of the multiple monitoring periods to obtain the channel utilization rate of the current channel.
After two STAs (i.e., a first STA and a second STA) establish a TDLS connection, one of the STAs (i.e., the first STA) starts to periodically monitor a data transmission condition of a current channel, that is, to acquire a busy level of the current channel.
The first STA starts monitoring from the start time (start time) of the period to obtain total _ mib _ cnt ', tx _ mib _ cnt', rx _ mib _ cnt ', and clear _ mib _ cnt' to calculate the idle fraction and channel utilization of the current channel.
The total duration of each period is denoted as total _ mib _ cnt ', the time count of the first STA sending the packet in the period is denoted as tx _ mib _ cnt', the time count of the first STA receiving the unicast packet and the broadcast multicast packet in the period is denoted as rx _ mib _ cnt ', and the time count of the channel idle in the period is denoted as clear _ mib _ cnt'. The idle ratio of the current channel in the period = clear _ mib _ cnt '/total _ mib _ cnt ', and the channel utilization of the current channel in the period = (tx _ mib _ cnt ' + rx _ mib _ cnt ')/total _ mib _ cnt '.
The first STA may monitor multiple periods to obtain the idle ratio of the current channel and the respective average value of the channel utilization, and may perform channel switching if the channel idle time of the current channel is short and the channel utilization is low within a period of time.
In an embodiment, with continuing reference to fig. 2, the performing the measurement on the one or more candidate channels in step S101 in fig. 1 includes:
step S204, sending a measurement notification to the second STA, wherein the measurement notification is used for notifying the second STA to be dormant and switching to each alternative channel;
step S205, completing the channel measurement of each candidate channel in cooperation with the second STA.
If one end STA (i.e. the first STA) detects that channel switching needs to be performed, channel measurement is triggered to measure the situation of other alternative channels.
When the first STA triggers channel measurement, the first STA may first notify the peer STA (i.e., the second STA) to sleep and switch to the alternative channel to be measured, so as to keep the connection with the peer and complete the measurement of the alternative channel.
Optionally, the channel measurement of each alternative channel is completed by using a radio measurement (radio measurement) mechanism in the 802.11k standard.
Optionally, after the channel measurement of each candidate channel is completed by using the wireless measurement mechanism in the 802.11k standard, the method may further include: and acquiring the Channel load (Channel load) and the interference strength of each alternative Channel so as to select a target Channel to be switched from the one or more alternative channels.
The channel load of each alternative channel can be obtained by the cooperation of the first STA and the second STA, by sending a channel load request and returning a report corresponding to the request.
In addition, information such as interference strength of each candidate channel can be acquired according to a wireless measurement mechanism in the 802.11k standard, so as to be used as a standard for judging whether each candidate channel is suitable as a target channel.
In an embodiment, after completing the channel measurement on each alternative channel in cooperation with the second STA in step S205 of fig. 2, the method may further include: notifying the second STA to switch back to the current channel to send a switch notification to the second STA.
And after the measurement is finished, the second STA switches back to the current channel, and the first STA selects the optimal clean channel as a target channel according to the measurement result of each alternative channel to perform channel switching. The first STA sends a switching notification to the second STA on the current channel, informs the second STA to switch to the target channel, enables the two to switch to the target channel together, and continues TDLS communication after switching to the target channel.
By the method, the STA in TDLS communication can monitor the communication condition of the current channel so as to switch the channel at a proper time, and the optimal channel is selected to execute switching through channel measurement, so that better channel utilization rate and communication effect are obtained.
Referring to fig. 3, an embodiment of the present invention further provides a method for STA channel switching under TDLS connection, where the method in fig. 3 may be executed by a second STA side, and the method includes:
