Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Bluetooth communication generally occurs in a 2.4G frequency band, and because of the free property of the 2.4G frequency band, in practical applications, bluetooth communication generally needs to share the 2.4G frequency band with other types of near field communication, for example, wifi communication, infrared communication, etc., which results in that bluetooth communication is easily interfered by other types of near field communication, especially wifi communication, which has a great influence on bluetooth communication in practical applications.
In order to avoid interference, the bluetooth communication introduces an Adaptive Frequency Hopping (AFH) technology, which can determine the quality of a bluetooth channel during the bluetooth communication process, so as to avoid bad channels with poor quality and perform data transmission on good channels with good quality.
Currently, the AFH technology determines the quality of the bluetooth channel by counting the quality of the data packets received by the bluetooth channel and/or the retransmission rate of the data packets, however, such a method has some outstanding problems, one of which is poor accuracy.
In view of this, embodiments of the present application provide a channel quality determination method, apparatus, device, storage medium, and program product, which can improve accuracy of determining a bluetooth channel quality.
It should be noted that, although only the bluetooth channel is taken as an example for description, readers will understand that the channel quality determination method provided in the embodiment of the present application is not limited to determining the channel quality of the bluetooth channel, but may also be applied to determining the channel quality of channels of other communication systems, and the embodiment of the present application is not particularly limited thereto.
Please refer to fig. 1, which illustrates an exemplary implementation environment related to a channel quality determining method according to an embodiment of the present application.
As shown in fig. 1, the implementation environment may include a first computer device 101 and a second computer device 102, wherein the first computer device 101 and the second computer device 102 establish a communication connection, for example, the communication connection may be a bluetooth communication connection.
It should be noted that, under the condition that the first computer device 101 and the second computer device 102 establish the bluetooth communication connection, the first computer device 101 and the second computer device 102 are both electronic devices having a bluetooth communication function, for example, the first computer device 101 and the second computer device 102 may be a personal computer, a notebook computer, a smart phone, a tablet computer, an internet of things device, a portable wearable device, and the like, wherein the internet of things device may be an intelligent sound box, an intelligent television, an intelligent air conditioner, an intelligent vehicle-mounted device, and the like, and the portable wearable device may be an intelligent watch, an intelligent bracelet, a head-mounted device, and the like. The embodiment of the present application does not limit the device types of the first computer device 101 and the second computer device 102.
It should be further noted that, although only two computer devices with communication connection established therebetween, that is, the first computer device 101 and the second computer device 102, are shown in fig. 1, readers will understand that in practical applications, there may be a case where 3 or more than 3 computer devices establish communication connection with each other (for example, the communication connection is bluetooth communication connection), and this case also belongs to the implementation environment related to the technical solution provided in the embodiment of the present application.
Referring to fig. 2, it shows a flowchart of a channel quality determining method provided by an embodiment of the present application, where an execution subject of the channel quality determining method may be a first computer device or a second computer device in the above implementation environment, and for convenience of description, it is referred to as a computer device in the following, and as shown in fig. 2, the channel quality determining method includes the following steps:
Optionally, the data receiving information may specifically indicate a retransmission rate of a data packet on the first channel, a frequency of receiving a good packet on the first channel, or a frequency of receiving a bad packet on the first channel, and the like, where a good packet refers to a good data packet that can be correctly analyzed by the computer device as the name implies, and a bad packet refers to a bad data packet that is a data packet that cannot be correctly analyzed by the computer device and is a concept corresponding to the good packet.
In an optional embodiment of the present application, the first channel may be a bluetooth channel, and may also be a channel of other communication systems, for example, the first channel may be a wifi channel, an infrared communication channel, a zigbee channel, and the like, and the type of the first channel is not specifically limited in this embodiment of the present application. In the following, only the first channel will be described as a bluetooth channel.
In practical applications, a plurality of bluetooth channels exist on the 2.4G frequency band, and the plurality of bluetooth channels can all support bluetooth communication, and in step 201, the computer device can obtain data receiving information of each bluetooth channel.
In the bluetooth communication, the computer devices which are mutually connected with the bluetooth communication have a master-slave part.
In a possible case, the master device may detect a packet reception status of each bluetooth channel, so as to obtain data reception information of each bluetooth channel, and then, the master device may transmit the obtained data reception information of each bluetooth channel to the slave device.
In another possible case, the master device and the slave device may respectively detect the data packet receiving status of each bluetooth channel, so as to respectively obtain the data receiving information of each bluetooth channel, and further, the master device and the slave device may also perform consistency negotiation on the respectively obtained data receiving information through bluetooth communication interaction, so as to make the data receiving information of each bluetooth channel obtained by the master device and the slave device respectively consistent.
In yet another possible case, the slave device may detect a packet reception status of each bluetooth channel to obtain data reception information of each bluetooth channel, and then the slave device may transmit the obtained data reception information of each bluetooth channel to the master device.
Of course, the above-mentioned manner for acquiring the data receiving information is only exemplary, and is not used to limit the protection scope of the technical solution provided in the present application, and in practical applications, any manner capable of acquiring the data receiving information should be included in the protection scope of the present application.
Wherein the interference information is used for characterizing the interfered condition of the first channel. Optionally, the interference information may indicate strength of an interfering signal on the first channel, level information of interference, and the like.
Similarly to the above, taking the first channel as the bluetooth channel as an example, in a possible case, the master device may detect the interference condition of each bluetooth channel, so as to obtain the interference information of each bluetooth channel, and then the master device may send the obtained interference information of each bluetooth channel to the slave device.
In another possible case, the master device and the slave device may respectively detect the interference status of each bluetooth channel, so as to respectively obtain the interference information of each bluetooth channel, and further, the master device and the slave device may perform consistency negotiation on the respective obtained interference information through bluetooth communication interaction, so as to make the interference information of each bluetooth channel obtained by the master device and the slave device respectively consistent.
In yet another possible case, the slave device may detect the interference condition of each bluetooth channel, so as to obtain interference information of each bluetooth channel, and then the slave device may transmit the obtained interference information of each bluetooth channel to the master device.
Of course, the above-mentioned manner for acquiring the interference information is merely exemplary, and is not used to limit the protection scope of the technical solution provided in the present application, and in practical applications, all the manners capable of acquiring the interference information should be included in the protection scope of the present application.
The computer device may determine, by combining the data reception information and the interference information of the first channel, the quality of the first channel, so as to obtain the channel quality of the first channel, where in an alternative embodiment of the present application, the channel quality may be one of a good channel and a bad channel.
It should be noted that the good channel and the bad channel are two opposite concepts, and generally speaking, the good channel has good channel quality, and communication can be normally performed on the good channel, and the bad channel has poor channel quality, and communication is difficult to normally performed on the bad channel.
According to the channel quality determination method provided by the embodiment of the application, the data receiving information and the interference information of the first channel are obtained, wherein the data receiving information is used for representing the receiving condition of the data packet on the first channel, and the interference information is used for representing the interfered condition of the first channel.
In an alternative embodiment of the present application, the computer device may periodically perform a process of acquiring interference information of the first channel. Specifically, taking the first channel as a bluetooth channel as an example, the computer device may periodically perform a process of acquiring interference information of the bluetooth channel after establishing a bluetooth communication connection with other computer devices. On this basis, the computer device may perform step 203 after acquiring the interference information of the first channel each time, that is, perform the step of determining the channel quality of the first channel according to the data reception information of the first channel and the interference information of the first channel.
In the existing AFH technology, if a certain bluetooth channel is determined to be a bad channel, the computer device will not continue to operate on the bluetooth channel, so that even if the bluetooth channel changes from the bad channel to a good channel, the computer device will not reuse the bluetooth channel, which results in poor flexibility of bluetooth communication.
In order to avoid the problem of the existing AFH technology, taking the first channel as the bluetooth channel as an example, in an optional embodiment of the present application, the computer device may perform the step of determining the channel quality of the bluetooth channel after acquiring the interference information of the bluetooth channel each time, and since the computer device may periodically determine the channel quality of the bluetooth channel, the computer device may timely find that a certain bluetooth channel is changed from a bad channel to a good channel, which may enable the bad and good bluetooth channels to be timely discovered and utilized, thereby improving the flexibility of bluetooth communication.
As described above, the interference information may indicate the strength of the interference signal on the first channel, in this case, please refer to fig. 3, which shows an alternative implementation manner for acquiring the interference information of the first channel provided by the embodiment of the present application, and as shown in fig. 3, the implementation manner may include the following steps:
As described above, the computer device may periodically perform the process of obtaining interference information of the first channel, and on this basis, the computer device may periodically scan the first channel to obtain the initial strength of the interference signal on the first channel. Meanwhile, the computer device may also periodically perform steps 302 and 303 described below.
The smoothing process is essentially a statistical process, the interference signal strength obtained after the initial strength is smoothed is a statistical strength, and the statistical process is performed on the initial strength, so that the obtained interference signal strength can avoid the influence of accidental factors, and the judgment of the interference condition of the first channel is prevented from being influenced by the conditions that the interference signal strength is suddenly increased and suddenly decreased.
As described above, the computer device may determine the quality of the first channel by combining the data reception information and the interference information of the first channel, so as to obtain the channel quality of the first channel, and on this basis, the embodiment of the present application will provide an exemplary manner for determining the channel quality of the first channel, where the manner is: and under the condition that the data receiving information of the first channel does not meet the first condition, determining the channel quality of the first channel according to whether the interference information of the first channel meets the second condition.
In practical applications, the quality of the packet reception status cannot completely and accurately reflect the channel quality because the packet reception status is affected by the distance between the data transceiver devices, the presence or absence of obstacles between the data transceiver devices, and the like in addition to the channel quality, and particularly, for short-distance communication such as bluetooth communication, the distance between the data transceiver devices, the presence or absence of obstacles between the data transceiver devices, and the like greatly affect the channel quality.
In view of the above factors, in the above-provided alternative way of determining channel quality, in the case that the data reception information of the first channel does not satisfy the first condition, the computer device may determine the channel quality of the first channel according to whether the interference information of the first channel satisfies the second condition, so that the two dimensions of the packet reception condition of the first channel and the interference condition of the first channel are sufficiently combined to determine whether the channel quality of the first channel is good or bad, and the accuracy of determining the channel quality of the first channel may be improved.
Optionally, in an optional implementation manner of the present application, if the data receiving information of the first channel satisfies the first condition, the first channel may be directly determined to be a good channel, but if the data receiving information of the first channel does not satisfy the first condition, the first channel is not directly determined to be a bad channel, but needs to be further determined in combination with the interference information of the first channel, that is, if the interference information of the first channel satisfies the second condition, even if the data receiving information of the first channel does not satisfy the first condition, the first channel is considered to be a good channel, and only if the data receiving information of the first channel does not satisfy the first condition, and the interference information of the first channel does not satisfy the second condition, the first channel is considered to be a bad channel.
It should be noted that the first condition and the second condition in the embodiment of the present application may be set according to specific contents of the data reception information and the interference information, and the general principle is that the first condition is set according to that the packet reception condition of the first channel is better than a certain packet reception condition, and the second condition is set according to that the interference condition of the first channel is better than a certain interference condition.
Taking as an example that the data reception information is used to indicate a frequency at which data is successfully received on the first channel, and the interference information is used to indicate an interfering signal strength on the first channel, in this case, the first condition includes: the frequency of successfully receiving data on the first channel is greater than a preset frequency threshold, and the second condition comprises: the strength of the interference signal on the first channel is less than a preset strength threshold.
Referring to fig. 4, based on the above definition of the first condition and the second condition, the exemplary manner of determining the channel quality of the first channel provided above may include the following steps:
After obtaining the channel quality of the first channel, in this embodiment of the present application, the computer device may further perform the following steps: and judging whether a second channel corresponding to the second communication system is occupied or not according to the channel quality of the plurality of first channels.
It should be noted that the first channel and the second channel both operate in the same frequency band, for example, the frequency band may be a 2.4G frequency band, and the plurality of first channels are located in the frequency band corresponding to the second channel, in other words, in an alternative embodiment of the present application, the computer device may determine whether the second channel is occupied according to the signal quality of the plurality of first channels in the frequency band corresponding to the second channel.
In an alternative embodiment of the present application, the first channel may be a bluetooth channel, and the second channel may be a channel used for other types of short-range communication in the 2.4G band besides bluetooth communication, for example, the second channel may be a wifi channel. Hereinafter, the description will be given by taking only the first channel as a bluetooth channel and the second channel as a wifi channel as an example.
As described above, since the 2.4G band is a free band, the 2.4G band is shared by bluetooth communication and other types of short-range communication, and in order to avoid the influence of other types of short-range communication on bluetooth communication, it is necessary to comprehensively determine the channel quality of the first channel in combination with the channel (i.e., the second channel) used by other types of short-range communication.
In order to achieve the purpose of comprehensively judging the channel quality of the first channel in combination with the second channel, in an optional embodiment of the present application, the computer device may judge whether the second channel is occupied according to the signal quality of a plurality of first channels in a frequency band corresponding to the second channel, and then, the computer device may perform secondary judgment on the channel quality of a plurality of first channels in the frequency band corresponding to the second channel according to whether the second channel is occupied, so as to finally obtain the channel quality of the plurality of first channels.
Optionally, the computer device may determine whether the second channel is occupied according to the channel quality of the plurality of first channels and a preset threshold.
Specifically, the computer device may determine a target number of bad channels in the plurality of first channels according to channel qualities of the plurality of first channels in a frequency band corresponding to the second channel, and then the computer device may determine whether the second channel is occupied according to whether the target number is greater than the preset threshold.
Generally, if the target number is larger (that is, the target number is greater than the preset number threshold), it indicates that the bad first channel is larger in the frequency band corresponding to the second channel, which generally indicates that the second channel is exactly the channel currently used by other types of short-range communication (for example, wifi communication), that is, the second channel is occupied, whereas if the target number is smaller (that is, the target number is less than or equal to the preset number threshold), it indicates that the bad first channel is smaller in the frequency band corresponding to the second channel, which generally indicates that there is no data transmission of other types of short-range communication (for example, wifi communication) in the second channel, that is, the second channel is unoccupied.
When the second channel is occupied, all the first channels in the frequency band corresponding to the second channel can be regarded as bad channels, and even the first channel determined as a good channel according to the data receiving information and the interference information can also be regarded as a bad channel, so that the interference of other types of short-distance communication can be avoided in the Bluetooth communication, and the quality of the Bluetooth communication can be ensured.
When the second channel is not occupied, the channel quality determined by the first channel in the frequency band corresponding to the second channel based on the data reception information and the interference information may be used as the final channel quality of the first channel, so that the bluetooth communication may be performed on a good channel therein.
In order to make the reader easily understand the technical solution provided in the embodiment of the present application, the embodiment of the present application will be described below with reference to the specific content in fig. 5. As shown in fig. 5:
