The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with aspects of the present application as detailed in the appended claims.

For example, personal communication service (PCS, Personal Communication Service) telephone, cordless telephone, Session Initiation Protocol (SIP) telephone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA, Personal Digital Assistant), etc. . The wireless terminal device may also be referred to as a system, a Subscriber Unit, a Subscriber Station, a Mobile Station, a Mobile, a Remote Station, and an Access Point. , Remote Terminal, Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

The wireless access point in the present application may be a wireless access device capable of providing a WIFI wireless network. In some embodiments, the wireless access point may be, for example, a wireless router, but the present application is not limited thereto.

FIG. 1 is a schematic diagram of a hardware circuit structure in a terminal device supporting a WIFI dual-frequency operation mode. As shown in FIG. 1, the functions of the devices in the circuit are configured as: a WIFI transceiver chip 20 connected to the CPU 10 for modulating and demodulating the WIFI signal; and a 2.4 GHz radio front-end mode respectively connected to the WIFI transceiver chip 20. Group (FEM, Front end module) 30 and 5GHZ FEM80, both FEMs are integrated with power amplifiers (PAs, Power Amplifiers), switches, low noise amplifiers (LNAs) and other components for receiving The WIFI signal is used for signal amplification; a 2.4 GHz filter (Filter) 40 connected to the 2.4 GHz radio frequency front end module 30 is used to filter and denoise the received WIFI signal; and the 2.4 G antenna 50 connected to the 2.4 GHz filter 40 And the 5G antenna 70 connected to the 5GHZ RF front-end module 50 is used to enable the terminal device to establish a wireless communication connection with the wireless router (AP, Access Point) 60 to complete signal transmission or reception.

2 is a diagram showing an example of spatial data flow of a terminal device supporting a WIFI dual-frequency operation mode. As shown in FIG. 2, since the WIFI communication system in the existing terminal device has only one WIFI transceiver chip 20, and the chip can only process data of one frequency band at a time, the data transmission mode of the above system is a single input single. The (SISO, Single Input Single Output) communication mode is a multiple input multiple output (MIMO) communication mode. When a communication connection is established between the terminal device and the wireless router 60, the same time is only in FIG. One WIFI path in 2.4GHZ or 5GHZ is activated in the enabled state, and the other path is not activated and is in the non-enabled state, that is, only one frequency band carrier carries data information at the same time.

In the related art, only a single WIFI path operates in the same time and another WIFI path is in a non-enabled state, so that not only the spectrum resources of each frequency band in the existing WIFI network but also the hardware resources in the terminal device cannot be fully utilized. It also cannot meet the current demand for high-speed data transmission.

When the terminal device and the wireless router in the prior art establish a wireless communication connection through the communication link, only one frequency band is used to carry the data information at the same time, and the efficient and reliable data transmission cannot be realized, and the existing WIFI network cannot be fully utilized. For the problem of the spectrum resources of the frequency band and the hardware resources in the medium, some embodiments of the present application improve the existing terminal equipment supporting the WIFI dual-frequency working mode.

As shown in FIG. 3, some embodiments of the present application have a WIFI transceiver chip disposed in each WIFI path. The 1#WIFI transceiver chip 20 is used to process the information stream data on the 2.4GHZ WIFI path, and the 2#WIFI transceiver chip 90 is used to process the information stream data on the 5GHZ WIFI path. Since the two WIFI paths of 2.4GHZ and 5GHZ are independent of each other, at the same time, the two WIFI paths can be activated at the same time, so that they are all enabled, and a communication chain is established with the corresponding WIFI signal band of the wireless router 60. The road, which in turn constitutes a dual data path, delivers a data task.

In other embodiments, the terminal device includes at least two RF front-end modules. The at least two radio frequency front-end modules are respectively matched with a transceiver, and the transceiver is disposed between the processor and the radio front-end module.

FIG. 4 is a schematic diagram of spatial data flow of WIFI dual-frequency carrier composite transmission in a terminal device according to some embodiments of the present disclosure. As shown in FIG. 4, the terminal device establishes a communication link with the wireless router 60, and the 2.4GHZ WIFI path and the 5GHZ WIFI path are simultaneously activated, and the two channels pass data in parallel, thereby broadening the transmission bandwidth and greatly improving the throughput. It should be noted that FIG. 4 is a schematic diagram of the simplified version of FIG. 3, omitting intermediate components such as FEM and Filter; in addition, the multi-frequency carrier composite transmission structure provided by some embodiments of the present application only takes two WIFI paths of 2.4 GHz and 5 GHz as an example. However, it is not limited to the circuit structure, and may be designed as a path for combining other frequency bands according to the signal frequency band covered by the wireless router 60. For example, there may be more WIFI channels. Here, only two examples are used as examples, but they are not limited thereto.

Some embodiments of the present application further provide a WIFI data transmission method, to activate a WIFI path corresponding to a preset requirement in a WIFI path corresponding to a plurality of different WIFI bands, to enter an enabled state, and bear between the wireless router and the wireless router. Data transfer tasks to increase the transfer rate.

FIG. 5 is a schematic flowchart of a WIFI data transmission method according to some embodiments of the present disclosure. The method is applied to the terminal device in FIG. 3 and FIG. 4, as shown in FIG. 5, the method mainly includes the following steps:

S101: Detect a signal frequency band of a WIFI network that covers the terminal device.

Specifically, the terminal device may detect a signal frequency band included in the WIFI network that covers the terminal device, for example, if the terminal device is currently connected to the wireless router, it may detect that the WIFI network provided by the currently connected wireless router includes Signal band.

S102: responsive to detecting that the WIFI network covering the terminal device includes at least two signal frequency bands, respectively controlling, in the terminal device, the WIFI path that meets the preset requirement in the WIFI path of the at least two signal frequency bands. Enable status.

If the WIFI network covering the terminal device is a network that has been accessed by the terminal device, the WIFI path corresponding to the preset requirement in the WIFI path corresponding to the other signal frequency bands currently used by the terminal device may be respectively controlled to enter. In the enabled state, the other signal frequency bands mentioned above are also the signal frequency bands supported by the network. For example, the current signal frequency band includes two frequency bands of 2.4 GHz and 5 GHz, and the terminal device is using the 2.4 GHz band, and if the 5 GHz band corresponds to the 5 GHz WIFI path. According to the preset requirement, the 5GHZ WIFI channel corresponding to the 5GHZ band can be controlled to enter the enable state, so that the two WIFI paths corresponding to the two bands of 2.4GHZ and 5GHZ are enabled; if the above-mentioned terminal device is covered The WIFI network is a target network to which the terminal device is to be connected, and the WIFI path that meets the preset requirement in each WIFI path working in the at least two signal frequency bands can be simultaneously controlled to enter an enabled state.

The preset requirement here may be preset. For example, when the terminal device supports WIFI communication of at least two signal frequency bands, the signal quality of different signal frequency bands may be different. Therefore, the preset may be selected here. Requirements, such as a WIFI path corresponding to a signal band whose signal quality meets a preset requirement.

S103: Assign a physical address to each WIFI path that enters an enabled state.

In some embodiments, one or more alternate physical addresses may be configured in addition to one primary physical address per terminal device. If the current terminal device is in carrier aggregation mode, that is, using two or at least two WIFI channels of different frequency bands for communication, the terminal device enables both the primary physical address and the alternate physical address, and the primary physical address and the alternate physical address are enabled. And respectively allocated to the WIFI path in the enabled state, so that the WIFI path establishes a communication link with the wireless reasoner according to the respective physical address, that is, a WIFI communication link uses a physical address to exchange information with the wireless router, so as to facilitate Distribution and identification of information flows.

For example, if the 2.4 GHz channel is currently being used, after the 5 GHz channel corresponding to the 5 GHz band is controlled to enter the enable state in step S102, the 5 GHz channel is assigned a spare physical address in this step, that is, the terminal device uses the single signal band. In the non-carrier aggregation mode, its primary physical address is used, and when it enters carrier aggregation mode, its alternate physical address is enabled. Further, if the terminal device simultaneously enables both the 2.4GHZ and 5GHZ paths, the primary physical address can be assigned to the 2.4GHZ path, and the alternate physical address can be allocated to the 5GHZ path accordingly. Of course, the primary physical address can also be assigned to The 5GHZ path, the corresponding physical address is allocated to the 2.4 GHz channel, and the specific allocation manner may be determined according to the specific network environment. Some embodiments of the present application are not specifically limited herein.

In addition, when the WIFI network provides more signal bands, for example, it includes not only the 2.4 GHz band, but also two bands in the range of 5.15-5.25 GHz and 5.725-5.825 GHz, according to the signal quality of the above three signal bands. The two signal bands are selected to be enabled, and the WIFI path operating in the selected signal band is established with the wireless router providing the WIFI network.

S104: Control each WIFI path entering the enabled state to perform data transmission with the wireless router according to a physical address, where the wireless router is configured to provide the WIFI network.

Each WIFI path uses its physical address to establish a communication link with the wireless router through active/passive scanning, as well as authentication and association procedures, and then transmits data over the established communication link.

As a possible implementation manner, the data content that is transmitted by the terminal device to the wireless access point may include the identity identification information of the terminal device, and the physicality of the WIFI path corresponding to each communication link in the terminal device. The address and data communication mode information, wherein the data communication mode information is used to indicate that a communication mode between the terminal device and the wireless access point is a carrier aggregation mode or a non-carrier aggregation mode. At this time, the wireless router can bind the physical address used by the WIFI path corresponding to the communication link having the same identity identification information according to the data transmission mode information, so that when there is a data transmission task between the terminal device and the router, The data to be transmitted can be allocated to each communication link to jointly carry the same data transmission task.

In addition, as the terminal device may also use a Long Term Evolution (LTE) network for communication, in order to ensure that the WIFI path enabled by the terminal device does not conflict with the LTE frequency band, the present application is a feasible implementation manner. Some embodiments also provide a way to change the WIFI path into the enabled state:

Obtaining frequency band information used by the terminal device to communicate using an LTE network;

Determining whether there is a conflict between a frequency band used by the terminal device in the LTE network and a frequency band used by the WIFI path entering the enabled state;

If it is determined that the frequency band used by the terminal device in the LTE network conflicts with the frequency band used by the WIFI path entering the enabled state, the WIFI path that enters the enabled state is changed.

In some embodiments, the foregoing steps may be performed after the WIFI path that meets the preset requirement is controlled to enter an enabled state, so that the terminal device may avoid a frequency band conflict when performing LTE communication.

The WIFI data transmission method provided by some embodiments of the present application, when the WIFI network covering the terminal device includes at least two signal frequency bands, the corresponding control terminal device works in the WIFI path of the multiple frequency bands, and the WIFI path conforms to the preset requirement. Enter the enable state, and assign a physical address to each WIFI path in the enabled state, so that each WIFI path can use its physical address to interact with the wireless router to transmit data streams, thereby broadening the transmission. Bandwidth ensures efficient data transmission without adding antennas.

In order to ensure the quality of the signal communication received by the WIFI channels used by the terminal, in the process of data transmission between the WIFI channels and the wireless routers according to the respective physical addresses, some embodiments of the present application also provide a monitoring method for each WIFI path:

S105: Real-time detection of a signal to noise ratio of a signal frequency band used by each WIFI path entering the enabled state.

Since the quality of the wireless network signal is mainly measured by the Signal-to-Noise Ratio (SNR), the SNR is the ratio of the signal to the noise. The larger the value, the higher the received signal and the background noise that affects the signal quality. The larger the difference, the better the signal quality. The SNR can be obtained according to the difference between the Received Signal Strength Indication (RSSI) and the background noise. The RSSI here indicates the signal strength received by the terminal device. Therefore, some embodiments of the present application monitor the signal quality of each path by detecting the SNR in real time during the data transmission between the WIFI path entering the enabled state and the wireless router according to the respective physical address.

For example, the RSSI received by the terminal device is -60dBm, the noise is -95dBm, and the SNR is =35dB. At this time, the signal quality is superior, and it is easier to extract the effective signal from the noise; however, if the RSSI=-85dBm, the noise It is -95dBm, and the SNR=10dB is obtained. The signal quality at this time is relatively poor, and it is difficult for the terminal device to extract the effective signal.

S106: Determine whether the signal to noise ratio of the signal frequency band used by each WIFI path entering the enabled state is consistent with the second preset condition.

If the signal-to-noise ratio of the signal band used by each WIFI path meets the second preset condition, the data transmission continues according to step S104; on the contrary, if the signal-to-noise ratio does not meet the signal band of the second preset condition, the execution is performed. Step S107.

S107: If it is determined that the signal frequency band does not meet the second preset condition, the WIFI path that controls the signal frequency band of the used signal band that does not meet the second preset condition enters a non-enabled state.

In this way, the connection between the WIFI path and the wireless router with poor signal quality is disconnected, and only the path with good signal quality is enabled to continue to transmit data.

In order to reduce the number of communication links that are simultaneously enabled by the terminal device, as another feasible implementation manner, the following method may also be adopted:

Detecting, in real time, the amount of data to be transmitted remaining between the terminal device and the wireless router;

Determining whether the remaining amount of data to be transmitted is smaller than a second preset data amount, and at this time, the amount of data to be transmitted between the terminal device and the wireless router is small, and the carrier aggregation mode may be turned off;

If it is determined that the remaining amount of data to be transmitted is less than the second preset data amount, at least one of the WIFI paths that enter the enabled state is controlled to enter a non-enabled state. For example, at least one of the WIFI paths that enter the enabled state can be controlled to enter a non-enabled state according to the specific number of remaining data to be transmitted, that is, the connection between the at least one standby physical address user and the wireless router is closed, for example, the last WIFI can be left. The communication path between the path and the primary physical address it uses and the wireless router.

It should be noted that the above three steps can be performed as a parallel scheme with S105-S107.

The WIFI data transmission method provided by some embodiments of the present application, when the WIFI network covering the terminal device includes at least two signal frequency bands, the corresponding control terminal device works in the WIFI path of the multiple frequency bands, and the WIFI path conforms to the preset requirement. Enter the enable state, and assign a physical address to each WIFI path in the enabled state, so that each WIFI path entering the enabled state can use its own physical address to interact with the wireless router to exchange data streams. In turn, the transmission bandwidth is broadened, and efficient data transmission is ensured without adding an antenna.

In order to ensure the quality of signal communication received by each WIFI path used by the terminal device, some embodiments of the present application further provide a WIFI data transmission method, and a flowchart thereof is shown in FIG. 6. The method is applied to the terminal device in FIG. 3 and FIG. 4, as shown in FIG. 6, the method mainly includes the following steps:

S201: Detect a signal frequency band of a WIFI network that covers the terminal device.

This step is similar to the above step S101, and details are not described herein again.

S202: Acquire SNR of each signal frequency band in response to detecting that the WIFI network covering the terminal device includes at least two signal frequency bands.

It should be noted that the SNR herein may also be other parameters that can be used to characterize the channel quality, which is not limited herein.

S203: Control, according to the acquired signal to noise ratio, the WIFI path of the signal band in the terminal device that operates in a signal to noise ratio that meets the first preset condition to enter an enabled state.

To improve the communication quality between the terminal device and the wireless router, when the WIFI network covering the terminal device includes at least two signal bands, the terminal device evaluates the signal quality of the currently connected WIFI network and each communication link, and then The WIFI path working in the signal band whose signal signal to noise ratio meets the first preset condition is selected to continue to enter the enable state.

S204: Assign a physical address to each WIFI path of the entry enable state.

This step is similar to the above step S103, and details are not described herein again.

S205: Acquire an amount of data to be transmitted between the terminal device and the wireless router.

S206: Determine whether the amount of data to be transmitted is greater than a preset amount of data.

S207: If it is determined that the amount of data to be transmitted is greater than the first preset data amount, using each WIFI path of the entry enable state and a physical address allocated for each WIFI path of the entry enable state, Establish a communication link with the wireless router separately.

The amount of data to be transmitted here represents the amount of data to be transmitted between the terminal device and the wireless router. If the amount of data to be transmitted between the terminal device and the wireless router is large, the carrier aggregation mode may be applied, and all the WIFI paths entering the enabled state are used for information transmission, and step S208 is performed; If the amount of data to be transmitted between the wireless routers is small, or there is no data transmission task, the communication link may be established with the wireless router using only a single WIFI path or a part of the WIFI path establishes a communication link with the wireless router, and other WIFI paths are established. In the dormant state, some embodiments of the present application select the number of WIFI channels to be opened according to the size of the data transmission volume, which can reduce the number of links that the terminal device simultaneously turns on when the amount of data to be transmitted between the terminal device and the wireless router is small. In turn, the number of carriers that the terminal device needs to monitor is reduced, thereby reducing the power consumption of the terminal device.

S208: Detect a signal transmission rate of each of the communication links.

The terminal device evaluates the signal quality of the currently connected WIFI network and communicates with each communication link, and feeds the analysis result to the wireless router, wherein the quality of the wireless network signal can be measured by SNR, for example, related to SNR. For the calculation method, refer to the description of the foregoing step S105, and details are not described herein again.

The wireless router receives the signal quality feedback from the terminal device, and configures the appropriate channel and signal transmission rate for each communication link of the terminal device, so that the information interaction between the two is smoothly performed. For example, the signal transmission rate of the 2.4 GHz channel can be configured to be R1, and the rate of the 5 GHz channel is R2. Then, the terminal device can detect the signal transmission rate configured by the wireless router for each communication link.

S209: Calculate a first information flow weight ratio of each of the communication links according to a signal transmission rate of each of the communication links.

Some embodiments of the present application provide a method for calculating a first information flow weight ratio for each WIFI path. In some embodiments, each of the communication links may be calculated according to the signal transmission rate. The data transmission ratio is such that the time of transmission of the same amount of data on all of the communication links is the shortest. In other words, on the premise of transmitting WIFI data of the same data amount, it is sufficient to calculate the proportion of data transmission undertaken by each communication link when the used time is the shortest, and set the data transmission ratio assumed by each of the communication links to The first information flow weight ratio.

Taking the two WIFI channels of 2.4 GHz and 5 GHz as an example, the first information flow weight ratios given to the 2.4 GHz communication link and the 5 GHz communication link are Q1 and Q2, respectively, where Q1+Q2=1, and 1≥Q1≥0, 1≥Q2≥0. If R1=R2, then Q1=Q2=0.5, then the total rate can be simplified to R=R1+R2; if R1>>R2, then Q1=1, Q2=0, then the total rate R=R1, if R2 >>R1, then Q2=1, Q1=0, then the total rate R=R2, that is, if the transmission rate of one of the communication links is much larger than other communication links, all the data is allocated to the communication link. If it is not the above relationship, use the formula:

Calculate the corresponding Q1 and Q2 when the information transmission time reaches the minimum value. In this case, the total rate can be simplified to R=R1+R2. For example, the amount of information to be transmitted [Mes]=600MB, the 2.4GHz communication link accessed by the terminal equipment. The rate R1 = 54 Mbps, the rate of the 5 GHz communication link R2 = 54 Mbps, then Q1 = 0.5 and Q2 = 0.5.

S210: Allocate data to be transmitted between the terminal device and the wireless router to each of the communication links according to a first information flow weight ratio of each of the communication links.

The terminal device sequentially divides the data to be transmitted [Mes] into n data packets, and then allocates them to the corresponding communication links according to the first information flow weight ratio of each communication link.

For example, the terminal device sends a series of information streams [Mes] to the wireless router. At this time, the terminal device uses two WIFI paths of 2.4 GHz and 5 GHz, and the 2.4 GHz communication link carries the data transmission or information flow of Q1*[Mes] ratio. The 5GHZ communication link carries the information flow of Q2*[Mes] ratio, and, Q1=Q2=0.5, the terminal device can divide [Mes] into 20 small data packets numbered 0-19, and even numbered small data. The packet is allocated to the 2.4GHZ communication link, and the odd-numbered small data packet is allocated to the 5GHZ communication link, and the two communication links complete the receiving task of the entire information flow [Mes] in parallel.

In some embodiments, after calculating the first information flow weight ratio of each communication link, the terminal device may further feed back the weight ratio information to the wireless router. If the wireless router has data to send to the terminal device, Then, the information flow [Mes] to be transmitted may be sequentially divided into n data packets, and then randomly allocated to the corresponding communication link according to the received weight ratio information, and the WIFI path in the terminal device sends the received data packet to the CPU. The processor, the CPU processor arranges the small packets received in parallel in order of numbers to obtain a complete information stream [Mes].

In the multi-frequency carrier aggregation WIFI data transmission method provided by some embodiments of the present application, when the WIFI network covering the terminal device includes at least two signal frequency bands, the WIFI path working in the frequency band of the terminal device is controlled to enter the enabled state at the same time. And jointly transmitting the data stream, thereby broadening the transmission bandwidth, and further ensuring efficient transmission of data without adding an antenna; at the same time, some embodiments of the present application further provide an information amount ratio method for each communication link carrier, according to The signal transmission rate of the WIFI network communicating with each communication link flexibly configures the information flow weight of each signal frequency band, maximizes the information capacity while ensuring the communication quality, and better utilizes the spectrum resources.

In addition, during the use of the terminal device, there may be a change in the location where the terminal device is located, a change in the number of devices in the same frequency band in the same location, and a switching channel, etc., in order to effectively correct the signal quality of the WIFI communication link caused by changes in the external environment. Variations, some embodiments of the present application also provide another WIFI data transmission method.

As shown in FIG. 6, after step S210 in the first embodiment, the method further includes the following steps:

S211: Real-time detection of a change in a signal transmission rate of each of the communication links.

In the process of transmitting WIFI data for each communication link, the change of the signal transmission rate corresponding to each of the communication links is detected in real time.

S212: Determine whether the change of the signal transmission rate exceeds a first preset threshold.

While the terminal device and the wireless router perform data transmission, the terminal device monitors the signal quality of the currently connected signal frequency band in real time, and interacts with the wireless router in time, so that the wireless router adjusts the signal transmission rate of the channel and each signal frequency band in time.

At the same time, the terminal device detects a change in the signal transmission rate of each path, and determines whether the path rate change Δ=R(t+1)-R(t) exceeds the first preset threshold. If the change value does not exceed the first preset threshold, the step S210 is continued to be performed according to the original weight ratio, and the data is transmitted according to the first information flow weight ratio; if the change value exceeds the first preset threshold, step S213 is performed.
