Description

Multi-frequency carrier aggregation WIFI data transmission method and device and terminal equipment

Technical Field

The invention relates to the technical field of communication, in particular to a multi-frequency carrier aggregation WIFI data transmission method and device and terminal equipment.

Background

With the rapid development of Wireless technologies, Wireless Fidelity (WIFI) is almost visible everywhere, and the WIFI signal frequency bands covered by different locations are different, specifically, a 2.4GHZ frequency band or a 5GHZ frequency band may be covered, or both frequency bands may exist.

The wavelength of the 2.4GHZ frequency band is relatively long, so that the optical fiber has the advantages of strong attenuation resistance and long transmission distance; however, the 2.4GHZ band is an unlicensed band, and there are many devices using the unlicensed band, so that sufficient stability cannot be ensured. On the contrary, although the wavelength of the 5GHZ band is relatively short, which makes it have the disadvantages of weak anti-attenuation capability and short transmission distance, the number of devices using the 5GHZ band is relatively small, so that the frequency spectrum resource of the band is relatively pure, and the quality of signal transmission can be ensured.

In order to realize that the mobile terminal can select the optimal signal frequency band for communication according to different application environments, currently, many terminal devices can support dual-frequency working modes of WIFI 2.4GHZ and 5 GHZ. Fig. 1 is a schematic diagram of a hardware circuit structure in a terminal device supporting a WIFI dual-frequency operating mode. As shown in fig. 1, the functions of the devices in the circuit are configured to: a WIFI transceiver chip 20 (also referred to as a modem) connected to the CPU10 for modem WIFI signals; a 2.4GHZ radio frequency Front End Module (FEM) 30 and a 5GHZ radio frequency Front end module 80 connected to the WIFI transceiver chip 20, where the two FEMs are integrated with Power amplifiers (PA, Power Amplifier), switches, Low Noise amplifiers (LNA, Low Noise Amplifier) and other elements for signal amplification of the received WIFI signal; the 2.4G Filter (Filter)40 is connected with the 2.4GHZ radio frequency front-end module 30 and is used for filtering and denoising the received WIFI signal; the 2.4G antenna 50 connected to the 2.4G filter 40 and the 5G antenna 70 connected to the 5GHZ rf front-end module 80 are both configured to enable the terminal device to establish a wireless communication link with the wireless router 60. As shown in fig. 2, for an exemplary illustration of spatial data flow of a terminal device supporting a WIFI dual-frequency operating mode, when a data flow connection is established between the terminal device and the wireless router 60, only a single WIFI channel of 2.4GHZ or 5GHZ is activated at the same time and is in an enabled state, and the other channel is in an inactive state, that is, only a carrier of one frequency band carries data information at the same time, so as to implement data transmission.

However, the above-mentioned operating mode that only one frequency band is used to carry data information at the same time fails to fully utilize the spectrum resources of each frequency band in the existing WIFI network and the hardware resources in the terminal device, so as to improve the data transmission rate between the terminal device and the wireless router 60.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

Aiming at the problem that when the terminal equipment and the wireless router establish data flow connection in the prior art, only one frequency band is used for bearing data information at the same time, and the frequency spectrum resources of each frequency band in the existing WIFI network and the hardware resources in the terminal equipment cannot be fully utilized, the embodiment of the invention improves the existing terminal equipment supporting the WIFI dual-frequency working mode.

Fig. 3 is a schematic diagram of a hardware circuit structure of WIFI dual-frequency carrier composite transmission in a terminal device according to an embodiment of the present invention, and as shown in fig. 3, in the embodiment of the present invention, each WIFI channel is provided with a WIFI transceiver chip, where a # 1 WIFI transceiver chip 20 is used to process information stream data of a 2.4GHZ channel, and a # 2 WIFI transceiver chip 90 is used to process information stream data of a 5GHZ channel. Because the two WIFI paths of 2.4GHZ and 5GHZ are mutually independent, the two WIFI paths can be simultaneously activated at the same time to be in an enabling state, and a communication link is established with the corresponding WIFI signal frequency band of the wireless router, so that a double data path is formed to transmit a data task.

Fig. 4 is a schematic view of spatial data flow of WIFI dual-frequency carrier composite transmission in a terminal device according to an embodiment of the present invention. As shown in fig. 4, the terminal device establishes a communication link with the wireless router 60, the 2.4GHZ WIFI channel and the 5GHZ WIFI channel are activated at the same time, and the two channels transmit data in parallel, so as to widen the transmission bandwidth and improve the throughput to a greater extent. It should be noted that fig. 4 is a simplified version of fig. 3, and intermediate elements such as FEM and Filter are omitted; in addition, the multi-frequency carrier composite transmission structure provided in the embodiment of the present invention only uses two WIFI channels, i.e., 2.4GHZ and 5GHZ, as an example, but is not limited to the circuit structure, and may also be designed as a channel combined with other frequency bands according to the signal frequency band covered by the wireless router 60.

Based on the hardware circuit design, in order to realize that data to be transmitted between the terminal device and the wireless router can be properly distributed to the two communication links, and better utilize the existing frequency spectrum resources to maximize the transmission rate, the embodiment of the invention also provides a multi-frequency carrier aggregation WIFI data transmission method.

Fig. 5 is a schematic flowchart of a multi-frequency carrier aggregation WIFI data transmission method according to an embodiment of the present invention. As shown in fig. 5, the method specifically includes the following steps:

s101: and establishing a communication link with at least two WIFI signal frequency bands.

Specifically, the terminal detects a signal frequency band contained in a WIFI network provided by a currently connected wireless router, then activates WIFI channels working in the signal frequency band according to the signal frequency band, and establishes communication links with the WIFI network by using the activated WIFI channels. For example, if the signal frequency bands covered by the current WIFI network are 2.4GHZ and 5GHZ frequency bands, two WIFI channels, 2.4GHZ and 5GHZ, in the terminal are respectively enabled to establish a communication link with the WIFI network.

When activated WIFI channels are used for establishing communication links with the WIFI network respectively, a main user physical address and a virtual user physical address can be set in the terminal at the same time, and if more than two WIFI channels are to be in an enabled state, the main user physical address and the virtual user physical address are allocated to each WIFI channel at the same time, namely, one WIFI communication link uses one physical address to perform information interaction with a wireless router, so that information flow is allocated and identified conveniently.

Further, when the signal frequency bands provided by the WIFI network are many, for example, the signal frequency bands include not only the 2.4GHZ frequency band, but also two frequency bands within the ranges of 5.15 GHZ to 5.25GHZ and 5.725 GHZ to 5.825GHZ, at this time, three WIFI channels working in the frequency bands in the terminal may be activated, two signal frequency bands may be selected for use according to the signal qualities of the three signal frequency bands, and a communication link is established between the WIFI channel working in the selected signal frequency band and the wireless router providing the WIFI network.

S102: a signal transmission rate for each of the communication links is detected.

Specifically, the terminal evaluates the Signal quality of communication between the currently accessed WIFI network and each communication link, and feeds back an analysis result to the wireless router, wherein the quality of the wireless network Signal can be measured by a Signal-to-noise Ratio (SNR), the SNR is a Ratio of a Signal to noise, and the larger the value of the SNR is, the larger the difference between a received effective Signal and background noise affecting the quality is, the better the Signal quality is, and according to a formula, the RSSI (received Signal Strength indication) is the Signal Strength received by the terminal.

For example, the RSSI received by the terminal is-60 dBm, the Noise is-95 dBm, and the SNR is 35dB, so that the signal quality is better and it is easier to extract effective signals from the Noise; however, if RSSI is-85 dBm and Noise is-95 dBm, SNR is 10dB, and the signal quality is poor, so that it is difficult for the terminal to extract valid information.

The wireless router receives the signal quality information fed back by the terminal, and configures an appropriate channel and a signal transmission rate for each communication link of the terminal, and performs information interaction between the two, for example, the rate of the 2.4GHZ path is configured to be R1, and the rate of the 5GHZ path is configured to be R2, and then the terminal can detect the signal transmission rate configured by the wireless router for each communication link.

S103: and calculating a first information flow weight ratio of each communication link according to the signal transmission rate of each communication link.

The embodiment of the invention provides a method for calculating a first information flow weight ratio of each WIFI channel, and particularly, the method comprises the steps of calculating a data transmission ratio borne by each communication link when the time for transmitting the same WIFI data is shortest according to the signal transmission rate, and setting the data transmission ratio borne by each communication link as the first information flow weight ratio.

Taking the 2.4GHz path and the 5GHz path as an example, the first information flow weight ratio respectively given to the 2.4GHz communication link and the 5GHz communication link is Q1 and Q2, wherein Q1+ Q2 is 1, and 1 is more than or equal to Q1 more than or equal to 0, and 1 is more than or equal to Q2 more than or equal to 0. If R1 ═ R2, then Q1 ═ Q2 ═ 0.5, at which time the total rate can be reduced to R1+ R2; if R1> > R2, Q1 is 1, Q2 is 0, and then the total rate R is R1, and if R2> > R1, Q2 is 1, Q1 is 0, and then the total rate R is R2, that is, if the transmission rate of one of the communication links is much greater than that of the other communication links, all data is allocated to the communication link; if not, then using the formula: t ═ Min {1/2[ (Q1 × Mes ])/R1+ (Q2 × Mes ])/R2] } calculates Q1 and Q2 corresponding to the minimum value of the information transmission time, at this time, the total rate can be simplified to R1+ R2, for example, the amount of information to be transmitted [ Mes ] (600 MB), the rate R1 of the 2.4GHz communication link accessed by the terminal is 54Mbps, the rate R2 of the 5GHz communication link is 54Mbps, at this time, Q1 is 0.5, and Q2 is 0.5.

S104: and distributing the WIFI data to be transmitted to each communication link according to the first information flow weight ratio of each communication link.

Specifically, the terminal divides the data [ Mes ] to be transmitted into n data packets in order, and then allocates the data packets to corresponding communication links according to a first information flow weight ratio of a data transmission proportion borne by each communication link.

For example, a terminal is to send a series of information flows [ Mes ] to a wireless router, where the terminal uses two paths, 2.4GHZ and 5GHZ, a 2.4GHZ link carries information flow transfer with Q1 × Mes ] ratio, a 5GHZ link carries information flow transfer with Q2 × Mes ] ratio, and Q1 equals Q2 equals 0.5, the terminal divides [ Mes ] into 20 small packets with numbers of 0-19, the even-numbered small packets are allocated to the 2.4GHZ communication link for transfer, the odd-numbered small packets are allocated to the 5GHZ communication link for transfer, and the two communication links perform receiving tasks of the entire information flow [ Mes ] in parallel.

Further, after calculating the first information flow weight ratio of each communication link, the terminal feeds back the weight ratio information to the wireless router, if the wireless router has data to send to the terminal, the information flow [ Mes ] to be transmitted is sequentially divided into n data packets, then the n data packets are randomly distributed to the corresponding communication link according to the received weight ratio, a WIFI access in the terminal sends the received data packets to a CPU processor of the terminal, and the CPU processor arranges all small data packets received in parallel according to the numbering sequence to obtain the complete information flow [ Mes ].

According to the multi-frequency carrier aggregation WIFI data transmission method provided by the embodiment of the invention, when the WIFI network covering the terminal comprises a plurality of signal frequency bands, the WIFI access working in the frequency band in the terminal equipment is correspondingly controlled to enter the enabling state at the same time, and data streams are transmitted together, so that the transmission bandwidth is widened, and the data transmission rate is further improved on the basis of not increasing the number of antennas; meanwhile, the embodiment of the invention also provides an information quantity matching method of each communication link carrier, the information flow weight of each signal frequency band is flexibly configured according to the signal transmission rate of the communication between the WIFI network and each communication link, the communication quality is ensured, the information capacity is maximized, and the frequency spectrum resources are better utilized.

Furthermore, in the using process of the terminal, situations such as the change of the location where the terminal is located, the change of the number of devices using the same frequency band in the vicinity of the location, channel switching and the like may occur, and in order to effectively correct the change of the signal quality of the WIFI communication link caused by the change of the external environment, the embodiment of the invention further provides another multi-frequency carrier aggregation WIFI data transmission method.

Fig. 6 is a schematic flowchart of a multi-frequency carrier aggregation WIFI data transmission method according to a second embodiment of the present invention. As shown in fig. 6, after step S104 in the first embodiment, the method further includes the following steps:

s105: detecting in real time a change in the signal transmission rate of each of the communication links.

And in the process of transmitting WIFI data by each communication link, detecting the signal transmission rate corresponding to each communication link in real time.

S106: and judging whether the change of the signal transmission rate exceeds a first preset threshold value.

When the terminal and the wireless router carry out data transmission, the terminal monitors the signal quality of the current connected signal frequency band at all times and interacts with the wireless router in time so that the wireless router can adjust the signal transmission rate of the channel and each signal frequency band in time.

Meanwhile, the terminal detects the change of the signal transmission rate of each channel and judges whether the change of the channel rate delta is R (t +1) -R (t) and exceeds a first preset threshold value. If the variation value does not exceed the threshold value, continuing to execute the step S104 according to the original weight value, and transmitting data according to the first information flow weight ratio; if the variation value exceeds the first preset threshold range by the first preset threshold, step S107 is performed.

S107: and if the change of the signal transmission rate exceeds a first preset threshold value, calculating a second information flow weight ratio of each communication link according to the changed signal transmission rate.

The step S103 in the above embodiment can be referred to for a specific calculation method, and details of this embodiment are not repeated herein.

S108: and distributing the remaining WIFI data to be transmitted to each communication link according to the second information flow weight ratio of each communication link.

The step S104 in the above embodiment may be referred to for a specific allocation method, and details of this embodiment are not repeated herein.

S109: and judging whether the WIFI data to be transmitted are transmitted completely.

When the data to be transferred is completed, and the amount of the data to be transferred between the terminal and the router is small, the carrier aggregation mode may be closed, and step S110 is executed.

S110: and if the WIFI data to be transmitted are transmitted, controlling each communication link to carry out carrier sensing according to a preset frequency, wherein the carrier sensing frequency of each communication link when the WIFI data to be transmitted are transmitted is greater than the preset frequency.

By reducing the carrier sensing frequency of each communication link, the number of carrier sensing times of each communication link in unit time is reduced. According to the embodiment of the invention, the carrier aggregation mode is closed in due time by judging the size of the data to be transmitted, occupied resources such as frequency spectrum and time slot are released, and communication links which need to be monitored by the terminal are reduced. And when a new data transmission task exists between the terminal and the router and the data volume to be transmitted is large, activating each WIFI access to enable the WIFI access to enter an enabling state, and continuing to transmit data by using the steps.

Further, in the using process of the terminal, a situation that the terminal uses LTE (Long Term Evolution) communication and WIFI to work simultaneously often exists, and if a signal frequency band of a channel occupied by LTE and a signal frequency band of a channel occupied by WIFI are close, the LTE and WIFI conflict and interfere with each other.

Fig. 7 is a schematic flowchart of a method for solving a conflict between multi-frequency carrier aggregation WIFI data transmission and LTE data transmission according to an embodiment of the present invention. In the above embodiment, after the terminal or the wireless router allocates the WIFI data to be transmitted to the WIFI access, the method includes the following steps:

s201: and acquiring information of the terminal using Long Term Evolution (LTE) communication.

Fig. 8 is a schematic structural diagram of a device for solving a conflict between multi-frequency carrier aggregation WIFI data transmission and LTE data transmission according to an embodiment of the present invention, and as shown in fig. 8, an LTE modem 230 and a WIFI modem 230 in a terminal interact with each other through a transmission line according to an embodiment of the present invention, where a channel conflict problem may exist because a signal frequency band of a 2.4G WIFI channel and a signal frequency band of LTE are relatively close to each other, and therefore the LTE modem 230 in the embodiment of the present invention may be a modem in a 2.4GHZ channel.

When the LTE has information transmission, an effective notification signal generated by the LTE modem 230 is transmitted to the WIFI modem 130, and the WIFI modem 130 generates a first notification signal according to the notification signal and transmits the first notification signal to the WIFI processing module in the CPU processor, so that the WIFI processing module learns information that the terminal uses LTE for long term evolution communication according to the first notification signal.

Further, information of the terminal using long term evolution LTE communication can be obtained by using information interaction between the LTE processing module 11 and the WIFI processing module 12 inside the CPU. Fig. 9 is a schematic structural diagram of a multi-frequency carrier aggregation WIFI data transmission and LTE data transmission conflict resolution apparatus according to a second embodiment of the present invention, as shown in fig. 9, when there is information transmission in LTE, an LTE processing module 11 generates a second notification signal and sends the second notification signal to a WIFI processing module 12 through a transmission line, so that the WIFI processing module obtains information that a terminal uses LTE communication according to the second notification signal.

S202: and judging whether the channel used by the LTE conflicts with the channel used by the communication link.

When the information that the terminal uses the long term evolution LTE communication is obtained, the channel information used by the LTE communication system is obtained, whether a channel used by the LTE and a channel used by the communication link conflict with each other is judged, if the channel conflict problem does not exist between the channel used by the LTE and the channel used by the communication link, the current information flow weight ratio is not corrected, the original ratio is kept, information transmission is performed, and when the channel conflict exists between the channel used by the LTE and the channel used by the communication link, step S203 is executed, so that the wireless router can correct the configuration ratio, the rate and the like of the communication link of the WIFI in time, and the rate of the WIFI data flow is ensured while the LTE.

S203: and if the channel used by the LTE conflicts with the channel used by the communication link, sending changed WIFI channel information to a wireless access point providing the WIFI signal frequency band.

The wireless router reconfigures a link channel and a signal transmission rate between the wireless router and the terminal according to the changed WIFI channel information fed back by the terminal and the stored WIFI and LTE conflict channel list.

S204: and calculating a third information flow weight ratio of each communication link according to the signal transmission rate of each communication link after the channel is changed.

Specifically, the terminal activates the weighting configuration instruction, and recalculates the information flow weight ratio of each WIFI communication link according to the newly configured signal transmission rate, where the specific calculation method may refer to step S103 in the foregoing embodiment, and this embodiment is not described herein again.

S205: and distributing the remaining WIFI data to be transmitted to each communication link according to the third information flow weight ratio of each communication link.

By the method, the problem of coexistence interference between LTE and WIFI during simultaneous working can be solved, and the transmission rate of WIFI data is ensured.

After the terminal finishes using the LTE communication, an embodiment of the present invention further provides a method for allocating data to be transmitted, which specifically includes the following steps:

s206: and acquiring the information that the terminal ends the LTE communication.

For a specific obtaining process, reference may be made to step S201, and details of the embodiment of the present invention are not described herein. In addition, the end information can be forwarded to the wireless router, so that the wireless router can decide whether to reconfigure a link channel and a signal transmission rate between the wireless router and the terminal according to the terminal feedback information.

S207: and judging whether the change between the signal transmission rate of each communication link after the LTE communication is finished and the signal transmission rate of each communication link before the LTE communication is used exceeds a second preset threshold value or not.

If the preset threshold range is not exceeded, executing step S208; on the contrary, step S209 is performed.

S208: and if the WIFI data to be transmitted does not exceed the second preset threshold, distributing the remaining WIFI data to be transmitted to each communication link according to the first information flow weight ratio of each communication link.

S209: and if the WIFI data exceeds a second preset threshold value, distributing the remaining WIFI data to be transmitted to each communication link according to a third information flow weight ratio of each communication link.

For example, before receiving the LTE information stream, the RSSI of the WIFI 2.4GHZ channel received by the terminal is-60 dBm, the SNR is 35dB, the RSSI of the 5GHZ channel is-65 dBm, and the SNR is 30 dB. After the LTE information stream is received, the RSSI of the 2.4GHZ channel received by the terminal is-55 dBm, the SNR is 40dB, the RSSI of the 5GHZ channel is-85 dBm, and the SNR is 10 dB. Before and after the LTE information flow is received, the signal quality of the WIFI access is obviously changed, and at the moment, the WIFI information flow is weighted according to the information flow weight ratio when the LTE information flow is received; on the contrary, if the RSSI of the 2.4GHZ channel received by the WIFI terminal is still-60 dBm after the LTE information stream is received, the SNR is 35dB, the RSSI of the 5GHZ channel is-65 dBm, and the SNR is 30dB, then the WIFI information stream is weighted according to the information stream weight ratio before the LTE information stream is received.

Compared with the mode of recalculating the information flow weight ratio by using the signal transmission rate of each communication link after the LTE communication is finished, the data distribution mode provided by the embodiment of the invention reduces the data processing amount of a CPU processor in the terminal and improves the data processing speed.
