Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method, a device, a terminal device and a storage medium for adjusting the position of a signal extender. Background Art

[0002] Within the wireless coverage range, when the wireless signal strength of the main router is too low, a signal extender is needed to relay and amplify the wireless signal. The signal extender can receive the wifi signal from the extended device and provide the wifi signal to the user device. It can also receive the wifi signal from the user device network and transmit the wifi signal to the extended device, completing two-way processing, thereby increasing the transmission distance of the wifi signal, improving the wifi coverage range, and ensuring the transmission quality.

[0003] So how should the best position of the signal extender be determined? In the prior art, one method is to determine the position of the signal extender by measuring the received power of the wireless signal and adjusting the position of the signal extender according to the size of the received power. However, this method does not take into account the bandwidth optimization problem of the extended network and the extended network, and cannot accurately calculate the actual bandwidth of the extended network, and cannot achieve balanced bandwidth configuration of the extended network and the extended network.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1 , is a flow chart of a method for adjusting the position of a signal extender provided in this embodiment of the present invention, the method comprising steps S1 to S4:

[0051] S1. Obtain the first basic maximum bandwidth and the first interference variable of the signal extender in the current communication environment; wherein the first interference variable includes a first idle transmission opportunity parameter and a first competition coefficient; the first idle transmission opportunity parameter is the time percentage of the signal extender when its channel does not have any other communication signal in a unit time when the signal extender is idle; the first competition coefficient is the time percentage of the signal extender when competing with other communication devices for the channel;

[0052] S2. Calculate a first actual maximum bandwidth corresponding to the signal extender at the current position according to the first basic maximum bandwidth, the first idle transmission opportunity parameter and the first competition coefficient;

[0053] S3, obtaining a second actual maximum bandwidth of the expanded device;

[0054] S4. According to the first actual maximum bandwidth and the second actual maximum bandwidth, the position of the signal extender is adjusted so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range.

[0055] Specifically, the first basic maximum bandwidth and the first interference variable of the signal extender in the current communication environment are obtained. The first basic maximum bandwidth refers to the bandwidth of the signal extender in an ideal communication environment, that is, a signal shielding and non-competition environment. According to the first basic maximum bandwidth and the first interference variable, the actual maximum bandwidth of the signal extender can be obtained. Among them, the first interference variable includes a first idle transmission opportunity parameter and a first competition coefficient. The first idle transmission opportunity parameter is the percentage of time when the signal extender is idle and its channel does not have any other communication signal in a unit time, that is, the current channel of the signal extender does not have a wifi signal or a non-wifi signal. The first idle transmission opportunity parameter can also be understood as the ratio of the idle transmittable time of the signal extender's channel to the total time per unit time. The acquisition of the first idle transmission opportunity parameter can be obtained by the signal extender's own port physical layer (Physical, PHY) carrier monitoring. In an interference environment, there are other wifi signals, this value will be less than 100%, and under complete shielding and no channel competition, the transmission opportunity is close to 100%. The first competition coefficient is the percentage of time that the signal extender strives for a channel when it is in channel competition with other communication devices. It is worth noting that the channel that the signal extender strives for here is the channel of other communication equipment, thereby obtaining additional bandwidth.

[0056] The first actual maximum bandwidth corresponding to the signal extender at the current position is calculated based on the first basic maximum bandwidth, the first idle transmission opportunity parameter and the first competition coefficient. When the position of the signal extender is adjusted, the first idle transmission opportunity parameter and the first competition coefficient will change accordingly, thereby changing the first actual maximum bandwidth.

[0057] Obtain the second actual maximum bandwidth of the expanded device. The second actual maximum bandwidth of the expanded device can be read through a pre-developed first collection software, which can be written in a programming language such as C language. The software has two functions: (1) calling the software driver interface to obtain the radio frequency parameters of the expanded device; (2) reading relevant data of a pre-set bandwidth database, which stores the second basic maximum bandwidth of the expanded device under different radio frequency parameters. Therefore, after obtaining the second interference variable of the expanded device under the current communication environment, the second actual maximum bandwidth of the expanded device can be calculated through the second basic maximum bandwidth and the second interference variable. In addition, when the signal extender and the expanded device both run the collection software, they can exchange bandwidth data through the TCP / IP protocol. When the expanded device is a router, the second actual maximum bandwidth is the actual maximum bandwidth of the router.

[0058] According to the first actual maximum bandwidth and the second actual maximum bandwidth, the position of the signal extender is adjusted so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range. In other words, the position of the signal extender is adjusted so that the second actual maximum bandwidth is as equal to the adjusted first actual maximum bandwidth as possible.

[0059] This embodiment of the present invention provides a method for adjusting the position of a signal extender, which can accurately calculate the actual bandwidth of the extended network, thereby solving the problem of bandwidth waste and inability to achieve bandwidth balance configuration caused by bandwidth imbalance between the extended network and the extending network.

[0060] As an improvement of the above scheme, the calculation formula of the first competition coefficient is δ1=(α1-β1)÷(1-β1), where δ1 is the first competition coefficient, α1 is the first transmission time percentage, and the first transmission time percentage refers to the percentage of time that the signal extender transmits signals per unit time; β1 is the first idle transmission opportunity parameter.

[0061] Specifically, the calculation formula of the first competition coefficient is δ1=(α1-β1)÷(1-β1), where δ1 is the first competition coefficient, α1 is the first transmission time percentage, and the first transmission time percentage refers to the time percentage of the signal extender performing signal transmission in unit time, that is, the first transmission time percentage includes the first idle transmission opportunity parameter and the time percentage for channel competition; β1 is the first idle transmission opportunity parameter.

[0062] As an improvement of the above solution, the first actual maximum bandwidth corresponding to the signal extender at the current position is calculated according to the first basic maximum bandwidth, the first idle transmission opportunity parameter and the first competition coefficient, specifically including:

[0063] According to the formula A1 = A a {β1+(1-β1)×δ1} calculates the first actual maximum bandwidth A1 corresponding to the signal extender at the current position, A a is the first basic maximum bandwidth.

[0064] Specifically, according to the formula A1=A a {β1+(1-β1)×δ1} calculates the first actual maximum bandwidth A1 corresponding to the current position of the signal extender, A a The calculation in this embodiment of the present invention corresponds to the interference variables only having the first idle transmission opportunity parameter and the first competition coefficient. According to these two interference variables, the calculation formula of the first actual maximum bandwidth is A1=A a {β1+(1-β1)×δ1}, if the interference variable changes, the calculation formula of the first actual maximum bandwidth will change accordingly. For example, when the interference variable is only the first idle transmission opportunity parameter, the calculation formula of the first actual maximum bandwidth is A1=A a β1.

[0065] As an improvement of the above solution, the first interference variable also includes a first packet loss rate; then,

[0066] The calculating, according to the first basic maximum bandwidth, the first idle transmission opportunity parameter and the first competition coefficient, to obtain a first actual maximum bandwidth corresponding to the signal extender at the current position specifically includes:

[0067] According to the formula A1 = A a {β1+(1-β1)×δ1}×(1-ε1) is used to calculate the first actual maximum bandwidth A1 corresponding to the current position of the signal extender, A a is the first basic maximum bandwidth, and ε1 is the first packet loss rate.

[0068] Specifically, the first interference variable also includes a first packet loss rate, that is, the first interference variable includes a first idle transmission opportunity parameter, a first competition coefficient and a first packet loss rate; then,

[0069] The calculating, according to the first basic maximum bandwidth, the first idle transmission opportunity parameter and the first competition coefficient, to obtain a first actual maximum bandwidth corresponding to the signal extender at the current position specifically includes:

[0070] According to the formula A1 = A a {β1+(1-β1)×δ1}×(1-ε1) is used to calculate the first actual maximum bandwidth A1 corresponding to the current position of the signal extender, A a is the first basic maximum bandwidth, and ε1 is the first packet loss rate.

[0071] Packet loss rate refers to the proportion of data packets that the receiver does not receive per unit time in an interference environment, or the proportion of erroneous data packets to the total data packets. When obtaining the basic maximum bandwidth, the packet loss rate is close to 0% because the communication environment is an ideal environment without interference. In the case of interference, the packet loss rate will be a floating value. These erroneous packets or packets that fail to be sent for other reasons cannot be calculated in the actual bandwidth because they are not valid transmission data. Therefore, the final actual bandwidth calculation should also be corrected by adding this factor. Therefore, the actual bandwidth corrected by the packet loss rate is more accurate than the actual bandwidth that has not been corrected, and is closer to the actual maximum bandwidth of the signal extender in the current communication environment.

[0072] As an improvement of the above solution, the step of obtaining the first basic maximum bandwidth and the first interference variable of the signal extender under the current communication environment specifically includes:

[0073] Acquire a first radio frequency parameter of the signal extender, and obtain the first basic maximum bandwidth of the signal extender according to a pre-stored correspondence between the first radio frequency parameter and the first basic maximum bandwidth;

[0074] Acquire a first idle transmission opportunity parameter and the first contention coefficient of the signal extender in a current communication environment.

[0075] Specifically, the first radio frequency parameter of the signal extender is acquired, and the first basic maximum bandwidth of the signal extender is obtained according to the pre-stored correspondence between the first radio frequency parameter and the first basic maximum bandwidth. Preferably, the correspondence between the first radio frequency parameter and the first basic maximum bandwidth is stored in a bandwidth database.

[0076] A first idle transmission opportunity parameter and a first contention coefficient of the signal extender in the current communication environment are obtained.

[0077] The bandwidth database records the corresponding transmit (transport, TX) and receive (receive, RX) direction throughput of the signal extender under different RF parameters in a signal shielded and non-competitive environment. During the measurement process, the device under test (i.e., the signal extender) and the accompanying device under test are used in the topology, and a communication connection is established between them, preferably a WiFi connection. The accompanying device includes a network card or extender that supports the WiFi protocol. Two PCs are used to control the device under test and the accompanying device under test respectively, and traffic software is used on the PC to measure the throughput of the device under test in the TX and RX directions multiple times by changing the RF parameters, and record them in the database.

[0078] RF parameters are divided into two categories: TX and RX:

[0079] The TX category includes: transmission mode (STBC, TXBF, CDD, MIMO), number of spatial streams, bandwidth, ampdu aggregation switch, protocol standard (802.11abgn / ac / ax), frame protection interval, and temperature;

[0080] The RX category includes: receiving mode (STBC, CDD, MIMO), received signal strength (RSSI), number of spatial streams, bandwidth, ampdu aggregation switch, protocol standard (802.11abgn / ac / ax), frame protection interval, and temperature;

[0081] Each time one of the parameters is changed, the corresponding throughput and RF variables are automatically read and recorded using the second collection software and input into the bandwidth database. This establishes a basic bandwidth model in an ideal shielded and non-competition environment. In actual work, these directly accessible RF parameters are read by the software to estimate the basic maximum bandwidth under the current ideal conditions.

[0082] The bandwidth database of the expanded device can also be measured and established according to the above method for use.

[0083] It should be noted that the second collection software is pre-developed and can be written in programming languages ​​such as C or Python. The program is divided into two parts. One part runs on the control PC and is used to call the iperf software to obtain the throughput; the other part runs on the device under test and is used to call the software driver interface to obtain the RF parameters of the device under test and transmit them to the program on the control PC through the TCP / IP protocol. The program on the control PC integrates the throughput and RF parameters, stores them in the bandwidth database, and then saves them on the flash storage medium of the device under test.

[0084] As an improvement of the above solution, the acquiring the first idle transmission opportunity parameter and the first competition coefficient of the signal extender in the current communication environment specifically includes:

[0085] Under the current communication environment, obtaining a plurality of idle transmission opportunity parameters and a plurality of contention coefficients of the signal extender within a preset time;

[0086] Calculate the average of multiple idle transmission opportunity parameters of the signal extender, and use the calculated average value as the first idle transmission opportunity parameter;

[0087] The maximum value among the multiple competition coefficients of the signal extender is used as the current competition coefficient of the signal extender, and the competition coefficient adjusted in the last round of the signal extender is compared with the current competition coefficient, and the larger value of the two is used as the first competition coefficient.

[0088] Specifically, because the idle transmission opportunity parameters and contention coefficients are dynamically fluctuating, multiple acquisitions are required to reduce errors. Therefore, in the current communication environment, multiple idle transmission opportunity parameters and multiple contention coefficients of the signal extender within a preset time are acquired;

[0089] The plurality of idle transmission opportunity parameters of the signal extender are averaged and the average value obtained is used as the first idle transmission opportunity parameter, that is, the size of the first idle transmission opportunity parameter is determined by using the average method.

[0090] The maximum value among the multiple competition coefficients of the signal extender is used as the current competition coefficient of the signal extender, and the competition coefficient adjusted in the previous round of the signal extender is compared with the current competition coefficient, and the larger value of the two is used as the first competition coefficient. The approximation method is used, and after multiple rounds of comparison, the maximum bandwidth algorithm is made more accurate.

[0091] As an improvement of the above solution, the step of obtaining the second actual maximum bandwidth of the expanded device specifically includes:

[0092] Obtain a second basic maximum bandwidth and a second interference variable of the expanded device in the current communication environment; wherein the second interference variable includes a second idle transmission opportunity parameter, a second competition coefficient corresponding to the expanded device when performing channel competition, and a second packet loss rate, and the second idle transmission opportunity parameter is the percentage of time when the expanded device is idle and its channel does not have any other communication signal in a unit time; the calculation formula of the second competition coefficient is δ2=(α2-β2)÷(1-β2), δ2 is the second competition coefficient, α2 is the second transmission time percentage, and the second transmission time percentage refers to the percentage of time that the expanded device performs signal transmission in a unit time; β2 is the second idle transmission opportunity parameter;

[0093] According to the formula A2 = A b{β2+(1-β2)×δ2}×(1-ε2) is used to calculate the second actual maximum bandwidth A2 corresponding to the extended device at the current position, A b is the second basic maximum bandwidth, and ε2 is the second packet loss rate.

[0094] Specifically, this embodiment of the present invention also uses the bandwidth calculation method of the signal extender to obtain the bandwidth of the extended device, as follows:

[0095] Obtain the second basic maximum bandwidth and the second interference variable of the expanded device in the current communication environment; wherein the second interference variable includes a second idle transmission opportunity parameter, a second competition coefficient corresponding to the expanded device when competing for a channel, and a second packet loss rate, and the second idle transmission opportunity parameter is the percentage of time when the expanded device is idle and its channel does not have any other communication signal in a unit time; the calculation formula of the second competition coefficient is δ2=(α2-β2)÷(1-β2), δ2 is the second competition coefficient, α2 is the second transmission time percentage, and the second transmission time percentage refers to the percentage of time that the expanded device performs signal transmission in a unit time; β2 is the second idle transmission opportunity parameter.

[0096] The second basic maximum bandwidth can also be obtained according to the second radio frequency parameter of the expanded device and the corresponding relationship between the second radio frequency parameter and the second basic maximum bandwidth. The parameters included in the second interference variable are similar to those in the first interference variable, and the corresponding meanings are the same, which will not be repeated here.

[0097] According to the formula A2 = A b {β2+(1-β2)×δ2}×(1-ε2) is used to calculate the second actual maximum bandwidth A2 corresponding to the current position of the extended device. b is the second basic maximum bandwidth, and ε2 is the second packet loss rate. Similarly, the calculation of the second actual maximum bandwidth is similar to the calculation of the first actual maximum bandwidth, which will not be repeated here.

[0098] As an improvement of the above scheme, the position of the signal extender is adjusted according to the first actual maximum bandwidth and the second actual maximum bandwidth so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range, specifically including:

[0099] If the first actual maximum bandwidth is greater than the second actual maximum bandwidth, adjusting the position of the signal extender so that the signal extender is away from the extended device, so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range;

[0100] If the first actual maximum bandwidth is smaller than the second actual maximum bandwidth, the position of the signal extender is adjusted so that the signal extender is close to the extended device, so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range.

[0101] Specifically, if the first actual maximum bandwidth is greater than the second actual maximum bandwidth, the position of the signal extender is adjusted to keep the signal extender away from the extended device so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range.

[0102] If the first actual maximum bandwidth is smaller than the second actual maximum bandwidth, the position of the signal extender is adjusted so that the signal extender is close to the extended device, so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range.

[0103] This is to avoid the situation where the extended network and the extended network always use the smaller bandwidth as the bottleneck for transmission when the bandwidth is not equal, thus causing bandwidth waste. Therefore, when adjusting the position of the signal extender, the extended network should be made equal to the extended network as much as possible, so as to optimize the overall network, reduce bandwidth waste, and improve the extension range and throughput.

[0104] As an improvement of the above solution, the first actual maximum bandwidth includes a first actual uplink maximum bandwidth and a first actual downlink maximum bandwidth, and the second actual maximum bandwidth includes a second actual uplink maximum bandwidth and a second actual downlink maximum bandwidth; then,

[0105] If the first actual maximum bandwidth is greater than the second actual maximum bandwidth, adjusting the position of the signal extender so that the signal extender is away from the extended device, so that the difference between the second actual maximum bandwidth and the adjusted first actual maximum bandwidth is within a preset range, specifically includes:

[0106] If the first actual uplink maximum bandwidth is greater than the second actual uplink maximum bandwidth, adjusting the position of the signal extender so that the signal extender is away from the extended device until the difference between the second actual uplink maximum bandwidth and the adjusted first actual uplink maximum bandwidth is within a preset range;

[0107] And, if the first actual downlink maximum bandwidth is greater than the second actual downlink maximum bandwidth, adjust the position of the signal extender so that the signal extender is close to the expanded device until the difference between the second actual downlink maximum bandwidth and the adjusted first actual downlink maximum bandwidth is within a preset range.
