Description

Technical Field

[0001] The present invention relates to but is not limited to licensed spectrum assisted access (LAA) technology, and in particular to a data transmission method and device, and a computer-readable storage medium. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) standardization organization has proposed a technology for the Long Term Evolution (LTE) network for unlicensed frequency bands, called License Assisted Access (LAA), which is used to transfer some services in the cellular network to the unlicensed frequency band. When the LAA technology uses the first unlicensed frequency band, it is necessary to use a licensed frequency band carrier as the main carrier, or called the primary cell (PCell), and one or more first unlicensed frequency band carriers as secondary cells (SCell). The main carrier and the first unlicensed frequency band carrier perform carrier aggregation (CA) to achieve simultaneous operation of multiple carriers to improve the data throughput of LTE. In addition to the LAA technology, there are also a large number of wireless fidelity (Wi-Fi) devices working in the second unlicensed frequency band. For example, using 5G For Wi-Fi devices using Wi-Fi technology, since the first unlicensed frequency band used by LAA technology and the second unlicensed frequency band used by 5G Wi-Fi technology are both 5 GHz frequency bands, there is a problem of frequency band interference when using LAA technology and 5G Wi-Fi technology at the same time, which greatly reduces the data throughput rate of the link using LAA technology and 5G Wi-Fi technology. In this regard, a method of allocating channels based on the load or channel usage of the two is proposed to avoid conflicts from the bottom layer of communication.

[0003] For a mobile broadband (MBB) device (for example, a wireless router), there is not only the problem of mutual interference between the first unlicensed frequency band and the second unlicensed frequency band of other MBB devices, but also the problem of mutual interference between its own first unlicensed frequency band and the second unlicensed frequency band. The prerequisite for adopting the above-mentioned related methods is that the LTE network adopting the LAA technology and the Wi-Fi network adopting the 5G Wi-Fi technology are uniformly controlled and managed by the network, but the Wi-Fi hotspot of the MBB device is determined by the wireless terminal connected to the MBB device, and the network cannot uniformly manage the LTE network adopting the LAA technology and the Wi-Fi network adopting the 5G Wi-Fi technology of the MBB device. In other words, the related technology cannot solve the problem of avoiding mutual interference between the first unlicensed frequency band and the second unlicensed frequency band corresponding to the MBB device under the premise of ensuring the data throughput rate of the data link corresponding to the MBB device. Summary of the invention

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Embodiment 1

[0029] Embodiment 1 of the present invention provides a data transmission method, such as Figure 1 As shown, the method may include:

[0030] S101: Acquire its own data transmission parameters, where the data transmission parameters are used to represent resource usage information corresponding to the network, or data transmission information corresponding to the network.

[0031] In the embodiment of the present invention, Figure 2In the communication connection diagram shown in the figure, when the base station 21 and the wireless terminal 23 (for example, a personal computer, a mobile phone) send and receive data, the MBB device 22 is usually used as an intermediate device to complete functions such as signal switching and routing. The hardware part of the MBB device 22 is a standard wireless network card, which enables itself to provide communication with a wireless access point (AP) through a driver. Point), so it is also called a wireless soft AP (SoftAP); taking the example of a base station 21 sending data to a wireless terminal 23 through an MBB device 22 (for example, a wireless router), the base station 21 can send downlink data to the MBB device 22 by using the LTE network, and then the MBB device 22 can forward the downlink data to the wireless terminal 23 by using the Wi-Fi network. Ideally, the process of the base station 21 sending data to the MBB device 22 and the process of the MBB device 22 sending data to the wireless terminal 23 are performed simultaneously and do not interfere with each other, so as to achieve the maximum data throughput of the data link from the base station 21 to the wireless terminal 23. However, in order to improve the data transmission rate of the LTE network, the LAA technology is often used, that is, the working frequency band of the LTE network is not only set to the first authorized frequency band corresponding to the LTE network, but also to the first unauthorized frequency band corresponding to the LTE network. Similarly, in order to improve the data transmission rate of the Wi-Fi network, the working frequency band of the Wi-Fi network is switched from the second authorized frequency band corresponding to the Wi-Fi network to the second unauthorized frequency band corresponding to the Wi-Fi network. The second authorized frequency band can be 2.4G The second unlicensed frequency band may be a 2.4 GHz frequency band corresponding to Wi-Fi, and the second unlicensed frequency band may be a 5 GHz frequency band corresponding to 5G Wi-Fi. Thus, when the MBB device 22 uses the LAA technology and the 5G Wi-Fi technology at the same time, since the first unlicensed frequency band of the LAA technology also uses a 5 GHz frequency band, the frequency bands will interfere with each other when the two technologies are used at the same time. In order to avoid mutual interference between the LAA technology and the 5G Wi-Fi technology while ensuring the data transmission rate, the MBB device 22 needs to reasonably and effectively utilize the LAA technology and the 5G Wi-Fi technology. Considering that the number of wireless terminals 23 connected to the MBB device 22 is uncertain, the data transmission parameters of the MBB device 22 itself may be obtained. The data transmission parameters are used to characterize the resource usage information corresponding to the network, or the data transmission information corresponding to the network. According to such data transmission parameters, a reasonable and effective way of using the LAA technology and the 5G Wi-Fi technology may be determined.

[0032] Furthermore, obtaining its own data transmission parameters may include: obtaining the transmission bandwidth of the first authorized frequency band corresponding to the LTE network, the transmission bandwidth of the first authorized frequency band representing resource usage information corresponding to the LTE network; determining the transmission bandwidth of the first authorized frequency band as a data transmission parameter; since according to the transmission bandwidth of the first authorized frequency band, it can be known that the LTE network only works at the highest transmission rate in the first authorized frequency band, thus, it can be determined whether it is necessary to increase the data transmission rate of the LTE network by using LAA technology.

[0033] Further, obtaining the data transmission parameters of the device itself may also include: obtaining a first data transmission rate corresponding to the LTE network and a second data transmission rate corresponding to the Wi-Fi network, the first data transmission rate representing the data transmission information corresponding to the LTE network, and the second data transmission rate representing the data transmission information corresponding to the Wi-Fi network; determining the first data transmission rate and the second data transmission rate as data transmission parameters; wherein the data transmission rate may include: bandwidth or throughput, the bandwidth representing the theoretical maximum data transmission rate of the channel, and the throughput representing the maximum data rate actually received and forwarded by the device; the throughput when the LTE network uses the LAA technology may be obtained as the first data transmission rate, and the throughput when the Wi-Fi network uses the 5G Wi-Fi technology may be obtained as the second data transmission rate. Since the throughput of the LTE network using the LAA technology and the throughput of the Wi-Fi network using the 5G Wi-Fi technology can be used to determine the influence of each of the two on the throughput of a data link corresponding to the MBB device 22, the use time of the LAA technology and the 5G Wi-Fi technology can be reasonably divided, so that the receiving data rate and the sending data rate of the MBB device 22 are kept consistent to the greatest extent, thereby improving the throughput of a data link from the base station 21 to the wireless terminal 23.

[0034] S102: Determine the state of a network switch according to the data transmission parameter, where the network switch is used to control the startup status of the LTE network and the Wi-Fi network.

[0035] In an embodiment of the present invention, the data transmission parameter may be the transmission bandwidth of the first authorized frequency band corresponding to the LTE network. Correspondingly, according to the transmission bandwidth of the first authorized frequency band, it can be known that the LTE network only works at the highest transmission rate in the first authorized frequency band. Then, by setting a preset bandwidth threshold, it is determined whether it is necessary to increase the data transmission rate of the LTE network by using the LAA technology. When the transmission bandwidth of the first authorized frequency band is less than the preset bandwidth threshold, it indicates that there is a high necessity to increase the data transmission rate of the LTE network by using the LAA technology, and priority is given to satisfying the use requirements of the LTE network for the LAA technology; when the transmission bandwidth of the first authorized frequency band is greater than or equal to the preset bandwidth threshold, it indicates that there is a low necessity to increase the data transmission rate of the LTE network by using the LAA technology, and priority is given to satisfying the use requirements of the Wi-Fi network for the 5G Wi-Fi technology.

[0036] Exemplarily, the LTE network's demand for the use of LAA technology can be learned from the state of the LAA switching switch, and the Wi-Fi network's demand for the use of high-speed frequency bands can be learned from the state of the Wi-Fi network switching switch; therefore, when the transmission bandwidth of the first authorized frequency band is less than the preset bandwidth threshold, the state of the LAA switching switch is determined; when the transmission bandwidth of the first authorized frequency band is greater than or equal to the preset bandwidth threshold, the state of the Wi-Fi network switching switch is determined.

[0037] S103: When the state of the network switch is on, the LTE network and the Wi-Fi network are controlled to operate in different frequency bands according to a preset transmission strategy corresponding to the state of the network switch.

[0038] In an embodiment of the present invention, the network switching switch may include an LAA switching switch and a Wi-Fi network switching switch, wherein the state of the LAA switching switch indicates the use of the LAA technology by the LTE network, the Wi-Fi network switching switch may be a 5G Wi-Fi switching switch, and the state of the Wi-Fi network switching switch indicates the use of the 5G Wi-Fi technology by the Wi-Fi network; then, when the state of the network switching switch indicates that the LAA switching switch is started, it indicates that the LTE network uses the LAA technology, then the working frequency band of the LTE network is controlled to be the first authorized frequency band and the first unlicensed frequency band, and the working frequency band of the Wi-Fi network is controlled to be the second authorized frequency band (for example, the 2.4 GHz frequency band); when the state of the network switching switch indicates that the Wi-Fi network switching switch is started, it indicates that the Wi-Fi network uses the 5G Wi-Fi technology, the working frequency band of the Wi-Fi network is controlled to be the second unlicensed frequency band (for example, the 5 GHz frequency band), and the working frequency band of the LTE network is controlled to be the first authorized frequency band.

[0039] On the one hand, the network switching switch is an LAA switching switch, and correspondingly, when the state of the network switching switch is on, according to the preset transmission strategy corresponding to the state of the network switching switch, the LTE network and the Wi-Fi network are controlled to operate in different frequency bands, which may include: obtaining the state of the LAA switching switch, when the state of the network switching switch indicates that the LAA switching switch is started, the working frequency band of the LTE network is controlled to be the first authorized frequency band and the first unlicensed frequency band, and the working frequency band of the Wi-Fi network is controlled to be the second authorized frequency band; when the state of the network switching switch indicates that the LAA switching switch is turned off, the working frequency band of the LTE network is controlled to be the first authorized frequency band, and the working frequency band of the Wi-Fi network is controlled to be the second unlicensed frequency band.

[0040] Furthermore, after obtaining the status of the LAA switching switch, it can also include: determining whether there is a first newly added device corresponding to the first unlicensed frequency band; when it is determined that there is a first newly added device, controlling the working frequency band of the Wi-Fi network to be the second authorized frequency band, and controlling the working frequency band of the LTE network to be the first unlicensed frequency band; when it is determined that there is no first newly added device, controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band, and controlling the working frequency band of the LTE network to be the first authorized frequency band; wherein the first newly added device corresponding to the first unlicensed frequency band may be a secondary service cell SCell of the LAA technology. When there is a secondary service cell SCell of the LAA technology, it indicates that the first unlicensed frequency band corresponding to the LAA technology is available. Otherwise, it indicates that the first unlicensed frequency band corresponding to the LAA technology is unavailable.

[0041] Further, after determining whether there is a first newly added device corresponding to the first unlicensed frequency band, it may also include: determining whether the data traffic of the LTE network is greater than a first preset traffic threshold; when the data traffic of the LTE network is greater than or equal to the first preset traffic threshold, controlling the working frequency band of the Wi-Fi network to be the second authorized frequency band, and controlling the working frequency band of the LTE network to be the first unlicensed frequency band; when the data traffic of the LTE network is less than the first preset traffic threshold, controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band, and controlling the working frequency band of the LTE network to be the first authorized frequency band; wherein, to determine whether the data traffic of the LTE network is greater than the first preset traffic threshold, it may be determined whether there is an activated SCell in the SCell of the LAA technology, because the activated SCell participates in data transmission, and when there is an activated SCell, it indicates that the LTE network uses the first unlicensed frequency band corresponding to the LAA technology for data transmission, otherwise, it indicates that the LTE network does not use the first unlicensed frequency band corresponding to the LAA technology for data transmission.

[0042] On the other hand, the network switching switch is a Wi-Fi network switching switch. Correspondingly, when the state of the network switching switch is on, according to the preset transmission strategy corresponding to the state of the network switching switch, controlling the LTE network and the Wi-Fi network to operate in different frequency bands may include: obtaining the state of the Wi-Fi network switching switch, when the state indicates that the Wi-Fi network switching switch is started, controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band corresponding to the Wi-Fi network, and controlling the working frequency band of the LTE network to be the first authorized frequency band; when the state indicates that the Wi-Fi network switching switch is off, controlling the working frequency band of the Wi-Fi network to be the second authorized frequency band corresponding to the Wi-Fi network, and controlling the working frequency band of the LTE network to be the first authorized frequency band and the first unlicensed frequency band.

[0043] Further, after obtaining the state of the Wi-Fi network switching switch, the method may also include: when the state indicates that the Wi-Fi network switching switch is started, determining whether there is a second newly added device corresponding to the second unlicensed frequency band; when it is determined that the second newly added device exists, controlling the working frequency band of the LTE network to be the first authorized frequency band, and controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band; when it is determined that the second newly added device does not exist, controlling the working frequency band of the LTE network to be the first unlicensed frequency band, and controlling the working frequency band of the Wi-Fi network to be the second authorized frequency band; wherein the second newly added device corresponding to the second unlicensed frequency band may be a wireless terminal accessing a 5G Wi-Fi network, and when there is a wireless terminal accessing the 5G Wi-Fi network, it indicates that the Wi-Fi network uses the 5 GHz frequency band, otherwise, it indicates that the Wi-Fi network does not use the 5 GHz frequency band.

[0044] Further, after determining whether there is a second newly added device corresponding to the second unlicensed frequency band, the method may further include: when determining that the second newly added device exists, determining whether the data traffic of the Wi-Fi network is greater than a second preset traffic threshold; when the data traffic of the Wi-Fi network is greater than or equal to the second preset traffic threshold, controlling the working frequency band of the LTE network to be the first authorized frequency band, and controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band; when the data traffic of the Wi-Fi network is less than the second preset traffic threshold, controlling the working frequency band of the LTE network to be the first unlicensed frequency band, and controlling the working frequency band of the Wi-Fi network to be the second authorized frequency band; wherein the data traffic of the Wi-Fi network may be the data traffic of a 5G Wi-Fi network, and the traffic of the Wi-Fi network operating on a 5 GHz frequency band; when the data traffic of the 5G Wi-Fi network is greater than or equal to the second preset traffic threshold, it indicates that the Wi-Fi network uses the 5 GHz frequency band for data transmission; otherwise, it indicates that the Wi-Fi network does not use the 5 GHz frequency band for data transmission.

[0045] It can be understood that based on the resource usage information of the LTE network on a data link, it can be known that the LTE network only works at the highest transmission rate in the first authorized frequency band, and it can be determined whether it is necessary to increase the data transmission rate of the LTE network by using LAA technology, and then determine a transmission strategy that is beneficial to the data transmission rate of the data link, which is used to control the LTE network and the Wi-Fi network to work in different frequency bands. This avoids the mutual interference problem between the LTE network and the Wi-Fi network working in the same frequency band, and improves the data transmission rate of the data link.

[0046] Embodiment 2

[0047] Based on the above embodiment 1, embodiment 2 of the present invention provides another data transmission method, such as Figure 3 As shown, after the above-mentioned acquisition of the data transmission parameters of the self, that is, after step S101, the method may further include the following steps:

[0048] S302: According to the data transmission parameters, the LTE network and the Wi-Fi network are controlled to work alternately in different frequency bands.

[0049] In an embodiment of the present invention, the data transmission parameter may include a first data transmission rate corresponding to the LTE network and a second data transmission rate corresponding to the Wi-Fi network. Correspondingly, according to the first data transmission rate and the second data transmission rate, the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band are determined; according to the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band, the LTE network is controlled to work in the first unlicensed frequency band and the Wi-Fi network is controlled to work in the second unlicensed frequency band alternately; wherein the first data transmission rate may be a throughput rate when the LTE network uses the LAA technology, and the second data transmission rate may be a throughput rate when the Wi-Fi network uses the 5G Wi-Fi technology; further, a plurality of rate indicators may be used to represent the throughput rate, for example, the average rate of the LTE network using the LAA technology over a period of time may be used to represent its own throughput rate; the average rate of the Wi-Fi network using the 5G Wi-Fi technology over a period of time may be used to represent its own throughput rate; the negotiated rate may be used to represent the throughput rate of the Wi-Fi network using the 5G Wi-Fi technology; the maximum theoretical rate when the LTE network uses the carrier aggregation technology may be used to represent the throughput rate of the LTE network using the LAA technology.

[0050] Exemplarily, since the receiving data rate and the sending data rate of the MBB device 22 are kept consistent to the greatest extent, the throughput of a data link corresponding to the MBB device 22 can be improved. Therefore, according to the throughput of the LTE network using the LAA technology and the throughput of the Wi-Fi network using the 5G Wi-Fi technology, the time-sharing ratio of the LTE network using the LAA technology and the time-sharing ratio of the Wi-Fi network using the 5G Wi-Fi technology can be determined. Based on the time-sharing ratio, in each preset working cycle, the LTE network is controlled to work in the first unlicensed frequency band and the Wi-Fi network is controlled to work in the second unlicensed frequency band alternately; for example, the throughput of the LTE network using the LAA technology is expressed as Th1, and the throughput of the Wi-Fi network using the 5G Wi-Fi technology is expressed as Th2. The time-sharing ratio r1 of the LTE network using the LAA technology can be calculated and expressed as:

[0051] r1=Th2 / (Th1+Th2) (1)

[0052] The time-sharing ratio r2 of the Wi-Fi network using 5G Wi-Fi technology is expressed as:

[0053] r2=Th1 / (Th1+Th2) (2)

[0054] It is known that the duration of the preset working cycle is T. Then, in each preset working cycle, the working duration T1 of the LTE network working in the first authorized frequency band and the first unlicensed frequency band is expressed as:

[0055] T1=T×r1=T×Th2 / (Th1+Th2) (3)

[0056] The working time T2 of the Wi-Fi network in the second unlicensed frequency band is expressed as:

[0057] T2=T×r2=T×Th1 / (Th1+Th2) (4)

[0058] Among them, the duration T of the preset working cycle remains unchanged during the working process, and the specific value can be obtained through experimental comparison; it can be seen that within the preset working cycle, the frequency band with a larger throughput is allocated a shorter working duration, so that the amount of data received (or sent) by the MBB device 22 through the LTE network and the amount of data sent (or received) through the Wi-Fi network within a period of time are consistent.

[0059] Further, according to the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band, controlling the LTE network to operate in the first unlicensed frequency band and the Wi-Fi network to operate in the second unlicensed frequency band alternately may include: determining the operating duration of the first unlicensed frequency band according to a preset working cycle, the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band; at the start time of each preset working cycle, controlling the operating frequency band of the LTE network to be the first unlicensed frequency band, and controlling the operating frequency band of the Wi-Fi network to be the second authorized frequency band; when it is determined that the time difference from the start time to the current time is equal to the operating duration of the first unlicensed frequency band, controlling the operating frequency band of the LTE network to be the first authorized frequency band, and controlling the operating frequency band of the Wi-Fi network to be the second unlicensed frequency band.

[0060] Further, according to the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band, controlling the LTE network to work in the first unlicensed frequency band and the Wi-Fi network to work in the second unlicensed frequency band alternately may also include: determining the working duration of the second unlicensed frequency band according to a preset working cycle, the time-sharing ratio of the first unlicensed frequency band and the time-sharing ratio of the second unlicensed frequency band; at the start time of each preset working cycle, controlling the working frequency band of the Wi-Fi network to be the second unlicensed frequency band, and controlling the working frequency band of the LTE network to be the first authorized frequency band; when it is determined that the time difference from the start time to the current time is equal to the working duration of the second unlicensed frequency band, controlling the working frequency band of the Wi-Fi network to be the first authorized frequency band, and controlling the working frequency band of the LTE network to be the first unlicensed frequency band.

[0061] It should be noted that, when the LTE network is controlled to work in the first unlicensed frequency band and the Wi-Fi network is controlled to work in the second unlicensed frequency band alternately according to the time-sharing ratio, in order to avoid mutual interference between the working frequency bands of the LTE network and the Wi-Fi network during switching, it is necessary to first turn off the first unlicensed frequency band of the currently working LTE network or the second unlicensed frequency band of the currently working Wi-Fi network, and then turn on the second unlicensed frequency band of the Wi-Fi network or the first unlicensed frequency band of the LTE network; for example, at the start time of a preset working cycle, the Wi-Fi network works in the second unlicensed frequency band, and the LTE network works in the first authorized frequency band. When the time difference from the start time to the current time is equal to the duration T2, the working frequency band of the Wi-Fi network is first controlled to be the second authorized frequency band, and then the working frequency band of the LTE network is controlled to be the first authorized frequency band and the first unlicensed frequency band.

[0062] It can be understood that, for the LTE network and the Wi-Fi network on a data link corresponding to the MBB device 22, a first data transmission rate when the LTE network uses the LAA technology and a second data transmission rate when the Wi-Fi network uses the 5G Wi-Fi technology are obtained. According to the first data transmission rate and the second data transmission rate, it can be known that the influence of the LAA technology and the 5G Wi-Fi technology on the data transmission rate of a data link corresponding to the MBB device 22 can be respectively determined. In this way, the time-sharing ratios of the LAA technology and the 5G Wi-Fi technology can be reasonably divided to control the LTE network to use the LAA technology and the Wi-Fi network to use the 5G Wi-Fi technology alternately. In this way, the problem of frequency band interference when the first unlicensed frequency band corresponding to the LAA technology and the second unlicensed frequency band corresponding to the 5G Wi-Fi technology are avoided at the same time, and the data transmission rate of the data link is improved.

[0063] Embodiment 3

[0064] In order to better reflect the purpose of the present invention, further examples are given based on the above embodiment 1.

[0065] Embodiment 3 of the present invention provides a data transmission method, such as Figure 4 As shown, the method may include:

[0066] S401: Obtain a transmission bandwidth of a first authorized frequency band corresponding to an LTE network, and execute step S402.

[0067] S402: Determine whether the transmission bandwidth of the first authorized frequency band is less than a preset broadband threshold. When the transmission bandwidth of the first authorized frequency band is greater than or equal to the preset broadband threshold, execute step S403; when the transmission bandwidth of the first authorized frequency band is less than the preset broadband threshold, execute step S407.

[0068] S403: Obtain the second state of the 5G Wi-Fi switch and execute step S404.

[0069] In the embodiment of the present invention, when it is determined that the transmission bandwidth of the first authorized frequency band is greater than or equal to the preset bandwidth threshold, the MBB device 22 may send a request message for turning on 5G Wi-Fi to a wireless terminal currently accessing the Wi-Fi network and having a 5G function, so that the user can control turning on and off 5G Wi-Fi through the wireless terminal; or the MBB device 22 may also automatically turn on 5G Wi-Fi; wherein the request message for turning on 5G Wi-Fi may be as follows: Figure 5 shown.

[0070] S404: Determine whether the second state of the 5G Wi-Fi switch is enabled. When the second state of the 5G Wi-Fi switch is enabled, execute step S405; otherwise, execute step S406.

[0071] S405: When the second state of the 5G Wi-Fi switch is enabled, the operating frequency band of the LTE network is controlled to be the first authorized frequency band.

[0072] In one embodiment, when the second state of the 5G Wi-Fi switch is enabled, the method further includes:

[0073] Determine whether there is a wireless terminal accessing the 5G Wi-Fi network; when there is a wireless terminal accessing the 5G Wi-Fi network, control the working frequency band of the LTE network to be the first authorized frequency band; otherwise, control the working frequency band of the LTE network to be the first authorized frequency band and the first unlicensed frequency band, and end the process.

[0074] In one embodiment, when the second state of the 5G Wi-Fi switch is enabled, the method further includes:

[0075] Determine whether there is a wireless terminal accessing the 5G Wi-Fi network; when there is a wireless terminal accessing the 5G Wi-Fi network, determine whether the current data traffic of the 5G Wi-Fi network is greater than a second preset traffic threshold, otherwise, control the working frequency band of the LTE network to be the first authorized frequency band and the first unlicensed frequency band, and end the process; when the current data traffic of the 5G Wi-Fi network is greater than or equal to the second preset traffic threshold, control the working frequency band of the LTE network to be the first authorized frequency band, otherwise, control the working frequency band of the LTE network to be the first authorized frequency band and the first unlicensed frequency band, and end the process.

[0076] Further, when the current data traffic of the 5G Wi-Fi network is greater than or equal to the second preset traffic threshold, after controlling the working frequency band of the LTE network to be the first authorized frequency band, the method further includes:

[0077] Detect the current data traffic of the 5G Wi-Fi network;

[0078] When it is detected that the current data traffic of the 5G Wi-Fi network is equal to 0, timing starts. When the time difference between the start timing time and the current time is greater than or equal to the preset time threshold, the operating frequency bands of the LTE network are controlled to be the first authorized frequency band and the first unlicensed frequency band, wherein the preset time threshold is the maximum duration during which no data transmission is allowed on the 5G Wi-Fi network. When it is detected during the timing process that the current data traffic of the 5G Wi-Fi network is greater than 0, timing is stopped and the current data traffic of the 5G Wi-Fi network continues to be detected.

[0079] S406: When the second state of the 5G Wi-Fi switch is off, control the working frequency band of the LTE network to be the first authorized frequency band and the first unlicensed frequency band.

[0080] S407: Obtain the first state of the LAA switching switch and execute step S408.

[0081] In the embodiment of the present invention, when it is determined that the transmission bandwidth of the first authorized frequency band is less than the preset bandwidth threshold, the MBB device 22 may send a request message for whether to enable LAA to a wireless terminal currently connected to the Wi-Fi network and having a 5G function, so that the user can control the on and off of LAA through the wireless terminal; or the MBB device 22 may also automatically enable LAA; wherein the request message for whether to enable LAA may be as follows: Figure 6 shown.

[0082] Furthermore, when the MBB device 22 detects that the first state of the LAA switching switch has changed or the working frequency band of the LTE network needs to be switched, the base station 21 can be informed of the first state of the LAA switching switch or the working frequency band of the LTE network by sending a channel quality indication (CQI, Channel Quality Indicator) or reference signal receiving power (RSRP, Reference Signal Receiving Power) of a specific value to the base station 21, so that the correct frequency band can be used for data transmission. For example, when it is determined that the working frequency band controlling the LTE network is the first authorized frequency band, or the user controls to turn off the LAA switching switch, the MBB device 22 sends a message with CQI equal to 0 to the base station 21, so that the base station 21 believes that the current wireless transmission conditions of the wireless terminal 23 are not good, and the base station 21 does not start LAA, thereby achieving the purpose of not using LAA technology in the LTE network.

[0083] S408: Determine whether the first state of the LAA switching switch is started. When the first state of the LAA switching switch is started, execute step S409; otherwise, execute step S410.

[0084] S409: When the first state of the LAA switch is enabled, the operating frequency band of the Wi-Fi network is controlled to be the 2.4 GHz frequency band.

[0085] In one embodiment, when the first state of the LAA switch is enabled, the method further includes:

[0086] Determine whether there is an SCell of LAA technology; when there is an SCell of LAA technology, control the working frequency band of the Wi-Fi network to be the 2.4 GHz band; otherwise, control the working frequency band of the Wi-Fi network to be the 5 GHz band, and end the process.

[0087] In one embodiment, when the first state of the LAA switch is enabled, the method further includes:

[0088] Determine whether there is an SCell of LAA technology; when there is an SCell of LAA technology, determine whether there is an activated Scell ​​in the SCell of LAA technology, otherwise, control the working frequency band of the Wi-Fi network to be the 5GHz band, and end the process; when there is an activated SCell in the SCell of LAA technology, control the working frequency band of the Wi-Fi network to be the 2.4GHz band, otherwise, control the working frequency band of the Wi-Fi network to be the 5GHz band, and end the process.

[0089] S410: When the first state of the LAA switch is off, the working frequency band of the Wi-Fi network is controlled to be the 5 GHz band.

[0090] It can be understood that according to the transmission bandwidth of the first authorized frequency band corresponding to the LTE network, it can be known that the LTE network only works at the highest transmission rate in the first authorized frequency band, and whether it is necessary to use LAA technology to improve the data transmission rate of the LTE network. According to the judgment result, it is determined to turn on one of the LAA switching switch and the 5G Wi-Fi switching switch to control the LTE network and the Wi-Fi network to work in different frequency bands. This avoids the mutual interference problem between the LTE network and the Wi-Fi network working in the same frequency band, and improves the data transmission rate of the data link.

[0093] S701: Obtain a first throughput rate when the LTE network uses the LAA technology, and a second throughput rate when the Wi-Fi network uses the 5G Wi-Fi technology.

[0094] S702: Determine, based on the first throughput rate and the second throughput rate, a first time-sharing ratio for the LTE network to use the LAA technology and a second time-sharing ratio for the Wi-Fi network to use the 5G Wi-Fi technology.

[0095] S703: Calculate a first working duration of the LTE network working in the first authorized frequency band and the first unlicensed frequency band and a second working duration of the Wi-Fi network working in the 5 GHz frequency band according to the duration of the preset working cycle, the first time-sharing ratio, and the second time-sharing ratio.

[0096] S704: In each preset working cycle, according to the first working duration and the second working duration, the working frequency band of the LTE network and the working frequency band of the Wi-Fi network are switched, so that the LTE network works alternately in the first authorized frequency band and the first unlicensed frequency band, and the Wi-Fi network works alternately in the 5 GHz frequency band.

[0097] It can be understood that the first throughput rate when the LTE network uses the LAA technology and the second throughput rate when the Wi-Fi network uses the 5G Wi-Fi technology are obtained, and the time-sharing ratio of the LAA technology and the 5G Wi-Fi technology are calculated according to the first throughput rate and the second throughput rate, which is used to control the LTE network to use the LAA technology and the Wi-Fi network to use the 5G Wi-Fi technology alternately in each working cycle. This avoids the problem of frequency band interference when the first unlicensed frequency band corresponding to the LAA technology and the second unlicensed frequency band corresponding to the 5G Wi-Fi technology are used at the same time, and improves the data transmission rate of the data link.
