Description

Data transmission method, device and storage medium

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a data transmission method, device, and storage medium.

Background

The terminal device typically includes a wireless communication module and a processor between which data transmission is required after the terminal device has accessed the wireless network via the wireless communication module. For example, the wireless communication module transmits data received from the wireless network to the processor or transmits data from the processor to other devices through the wireless network. In general, the wireless communication module and the processor use a data transmission interface protocol to perform data transmission, where the data transmission interface protocol refers to a communication mode and a requirement that need to be complied with between interfaces that need to perform data transmission. For example, the wireless communication module and the processor typically employ a peripheral component interconnect standard (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIe), a high-speed serial computer expansion bus standard, for data transfer.

In the related art, the terminal device may access a 2.4G wireless fidelity (WIRELESS FIDELITY, WIFI) network, a 5G WiFi network, or the like through a wireless communication module. After the terminal device accesses the wireless network, the wireless communication module generally uses a pre-negotiated fixed data transmission interface protocol to communicate with the processor, such as using a pre-negotiated fixed first generation PCIe protocol or a second generation PCIe protocol to perform data transmission with the processor. The technical scheme for carrying out data transmission by adopting the fixed data transmission interface protocol between the wireless communication module and the processor has certain limitation, has lower flexibility and can not meet the data transmission requirement.

Disclosure of Invention

The application provides a data transmission method, equipment and a storage medium, which can improve the flexibility of data transmission between a wireless communication module and a processor, meet the data transmission requirement, and can solve the problem of radio frequency interference caused by the data transmission between the wireless communication module and the processor. The technical scheme is as follows:

In a first aspect, a data transmission method is provided, applied to a terminal device, where the terminal device includes a wireless communication module and a processor, and the method includes: the wireless communication module detects the network system of a wireless network accessed by the terminal equipment; the wireless communication module sends the detection result to the processor; and the processor selects a data transmission interface protocol matched with the network system according to the detection result and transmits data with the processor. The network system at least comprises a first network system and a second network system, the data transmission interface protocol matched with the first network system is a first data transmission interface protocol, the data transmission interface protocol matched with the second network system is a second data transmission interface protocol, the first network system and the second network system are different, and the first data transmission interface protocol and the second data transmission interface protocol are different.

Therefore, the flexibility of data transmission between the wireless communication module and the processor is improved, the data transmission interface protocol adopted for data transmission between the wireless communication module and the processor is ensured to be matched with the network system of the wireless network accessed by the terminal equipment, so that the adopted data transmission interface protocol can meet the data transmission requirement of the accessed network system, for example, the adopted data transmission interface protocol can be ensured to be capable of considering the EMI performance and the transmission rate.

As an example, the first network system is a first WiFi network, and the first data transmission interface protocol is a first PCIe protocol; the second network system is a second WiFi network, the second data transmission interface protocol is a second PCIe protocol, the working frequency bands of the second WiFi network and the first WiFi network are different, and the data transmission rates corresponding to the first PCIe protocol and the second PCIe protocol are different.

Therefore, under the condition that the terminal equipment is accessed to the WiFi network, the PCIe protocol adopted for data transmission between the wireless communication module and the processor is matched with the network system of the WiFi network connected with the terminal equipment, so that the adopted PCIe protocol can meet the data transmission requirement of the connected network system, for example, the adopted PCIe protocol can be ensured to be capable of considering the EMI performance and the transmission rate.

As one example, the first WiFi network is a 2.4G WiFi network, and the first PCIe protocol is a first generation PCIe protocol; the second WiFi network is a 5G WiFi network, and the second PCIe protocol is a second generation PCIe protocol or a third generation PCIe protocol. That is, if the network system of the wireless network is detected to be the 2.4G WiFi network, the processor negotiates with the pcie1.0 protocol to perform data transmission with the processor. If the network system of the wireless network is detected to be a 5G WiFi network, negotiating with the processor to select PCIE2.0 protocol or PCIE3.0 protocol for data transmission with the processor.

When the connected wireless network is detected to be a 2.4G WiFi network, the PCIE1.0 protocol is negotiated with the processor to carry out data transmission with the processor, so that the problem of radio frequency interference caused by interference noise generated by PCIe data signals under the PCIE2.0 protocol and the PCIE3.0 protocol and same frequency with the 2.4G WiFi network can be avoided, the throughput rate of the 2.4GWiFi network is improved, and further the user experience is improved. When the connected wireless network is detected to be a 5G WiFi network, the processor is negotiated with the PCIE2.0 protocol or PCIE3.0 protocol to perform data transmission with the processor, so that higher data transmission rate can be ensured under the condition that data signal noise generated under the PCIE2.0 protocol or PCIE3.0 protocol has little influence on the 5G WiFi network. According to different network modes, the PCIe protocol switching scheme is carried out, and the EMI performance and the transmission rate can be considered.

As an example, the wireless communication module detects a network system of a wireless network accessed by the terminal device, including: the wireless communication module acquires network system information of a wireless network, wherein the network system information is used for indicating the network system of the wireless network; and the wireless communication module determines the network system of the wireless network according to the network system information.

As an example, before the wireless communication module sends the detection result to the processor, the method further includes: if the wireless communication module detects that the terminal equipment is accessed to the wireless network through the wireless communication module, handshake is carried out between the wireless communication module and the processor; the wireless communication module performs the step of transmitting the detection result to the processor in the process of handshaking with the processor.

Therefore, the wireless communication module can detect the network type of the wireless network accessed by the terminal equipment before establishing connection with the processor, and feeds back the detected network type to the processor in the process of establishing connection with the processor, so that the processor can directly adopt a data transmission interface protocol matched with the network type to carry out data transmission with the wireless communication module after establishing connection with the wireless communication module, and the data transmission efficiency can be improved.

In a second aspect, a data transmission method is provided, applied to a terminal device, where the terminal device includes a wireless communication module and a processor, and the method includes: the wireless communication module detects modulation and coding strategy MCS negotiated by the terminal equipment and the access point, wherein the access point is the access point of the wireless network accessed by the terminal equipment; the wireless communication module sends the detection result to the processor; and the processor selects a data transmission interface protocol matched with the MCS to transmit data with the wireless communication module according to the detection result. If the MCS belongs to the first MCS set, the data transmission interface protocol matched with the MCS is the first data transmission interface protocol, if the MCS belongs to the second MCS set, the data transmission interface protocol matched with the MCS is the second data transmission interface protocol, the intersection of the first MCS set and the second MCS set is null, and the first data transmission interface protocol and the second data transmission interface protocol are different.

Because the MCS negotiated by the terminal device and the access point of the wireless network is related to the network system of the wireless network and the network transmission rate of the wireless network can be determined to a certain extent, the wireless communication module feeds back the negotiated MCS to the processor by detecting the MCS negotiated by the terminal device and the access point of the wireless network, so that the processor selects a data transmission interface protocol matched with the MCS negotiated by the terminal device to perform data transmission with the wireless communication module, the selected data transmission interface protocol can be ensured to be matched with the MCS and the network system corresponding to the MCS can be matched, the dynamic association of the network transmission rate-MCS-data transmission interface protocol of the wireless network is realized, the flexibility of data transmission between the wireless communication module and the processor is improved, and the EMI performance and the transmission rate can be considered.

As an example, the first data transmission interface protocol is a first PCIe protocol, the second data transmission interface protocol is a second PCIe protocol, and the data transmission rates corresponding to the first PCIe protocol and the second PCIe protocol are different.

Therefore, under the condition that the terminal equipment is accessed to the WiFi network, the PCIe protocol adopted for data transmission between the wireless communication module and the processor is matched with the MCS negotiated by the terminal equipment, so that the adopted PCIe protocol can meet the data transmission requirement of the negotiated MCS, for example, the adopted PCIe protocol can be ensured to be capable of considering the EMI performance and the transmission rate.

As an example, the wireless communication module detecting an MCS negotiated by a terminal device with an access point, comprising: the wireless communication module acquires an index value of the MCS negotiated by the terminal equipment and the access point; if the index value belongs to the first MCS index value set, determining that the MCS belongs to the first MCS set; if the index value belongs to the second MCS index value set, determining that the MCS belongs to the second MCS set.

As an example, the first data transfer interface protocol is a first generation PCIe protocol and the second data transfer interface protocol is a second generation PCIe protocol or a third generation PCIe protocol.

As an example, the first MCS index value set is MCS0-MCS7 and the second MCS index value set is MCS8-MCS11. That is, if the index value of the negotiated MCS belongs to MCS0 to MCS7, the processor selects pcie1.0 protocol and performs data transmission with the wireless communication module. If the index value of the negotiated MCS belongs to MCS8-MCS11, the processor selects PCIE2.0 protocol or PCIE3.0 to perform data transmission with the wireless communication module.

When the index value of the negotiated MCS belongs to MCS 0-MCS 7, the processor selects PCIE1.0 protocol and the wireless communication module for data transmission, so that the problem of radio frequency interference caused by interference noise of PCIe data signals with the same frequency as the 2.4G WiFi network under the PCIE2.0 protocol and the PCIE3.0 protocol can be avoided under the condition that the connected network is the 2.4G WiFi network, the throughput rate of the 2.4G WiFi network is improved, and the user experience is further improved. When the index value of the negotiated MCS belongs to MCS 8-MCS 11, the processor selects PCIE2.0 protocol or PCIE3.0 and the wireless communication module for data transmission, so that higher data transmission rate can be ensured under the condition that data signal noise generated under the PCIE2.0 protocol or PCIE3.0 protocol has little influence on the 5G WiFi network, and the PCIe protocol adapted to the higher network transmission rate can be adopted for data transmission with the processor under the condition that the network transmission rate of the 5G WiFi network is higher. In summary, when the terminal device performs wireless network communication, dynamic association of network transmission rate-MCS-data transmission interface protocol of the wireless network can be realized, and EMI performance and network transmission speed are both considered.

As an example, the wireless communication module detecting a modulation and coding scheme MCS negotiated by a terminal device and an access point, comprising: and if the wireless communication module detects that the terminal equipment negotiates the MCS with the access point for the first time or renegotiates the MCS, detecting the MCS negotiated by the terminal equipment and the access point.

In a third aspect, a data transmission apparatus is provided, which has a function of implementing the above-described behavior of the data transmission method in the first aspect. The data transmission device comprises at least one module for implementing the data transmission method provided in the first aspect or the second aspect.

In a fourth aspect, there is provided a data transmission apparatus including a processor and a memory in a structure thereof, the memory being configured to store a program for supporting the data transmission apparatus to execute the data transmission method provided in the first aspect, and to store data for implementing the data transmission method according to the first or second aspect.

Before explaining the data transmission method provided by the embodiment of the present application in detail, the nouns related to the embodiment of the present application are explained.

Data transmission interface protocol: communication modes and requirements, such as PCIe protocol, to be complied with between interfaces that need to perform data transmission.

PCIe: a high-speed serial computer expansion bus standard, also known as PCI-E. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission, and connected devices allocate exclusive channel bandwidths and do not share bus bandwidths. PCIe is preceded by PCI and PCI-X and uses multiple pairs of high-speed serial buses for point-to-point connections, thus providing very high bus bandwidth, as compared to conventional parallel bus architectures. Meanwhile, due to compatibility and mature technology of upper layers and PCI, PCIe has become a standard interface in applications such as desktops, notebooks and servers, and is becoming more and more popular in many applications requiring high-speed data exchange.

PCIe protocols include a variety of specifications that can meet the demands of low-speed devices and high-speed devices that will occur at a time in the future. For example, PCIe protocols include PCIe protocols of different generations, such as first generation PCIe (PCIe 1.0) protocol, second generation PCIe (PCIe 2.0) and third generation PCIe (PCIe 3.0) protocols. Wherein the transmission rates of PCIe protocols of different generations are different. For example, the PCIE1.0 protocol has a transmission rate of 2.5Gb/s, i.e. supports 2.5G bits per second transmission; the transmission rate of PCIE2.0 protocol is 5Gb/s; the PCIE3.0 protocol has a transmission rate of 8Gb/s.

Wireless fidelity (WIRELESS FIDELITY, wiFi) network: a communication network employing wireless technology. There are corresponding standards in any industry, and the standards are usually formulated by the enterprise association or alliance of the industry center, while there are corresponding standards in the WiFi network field, namely wireless technology standards. For example, the 2.4G WiFi network is a WiFi network adopting the 2.4G standard, and the 5G WiFi network is a WiFi network adopting the 5G standard.

2.4G WiFi network: generally refers to WiFi networks with frequency bands between 2.400GHz and 2.4835 GHz. Routers, which are commonly found in home use, are produced based on the ieee802.11b technology standard, which enables two-way transmission, and coverage distances are affected by device power, which can cover a range of about 10-50 meters in diameter (related to interference, obstructions, device installation environments).

5G WiFi network: generally refers to a WiFi network with a frequency band of 5 GHz. The biggest difference between the 5G WiFi network and the 2.4G WiFi network is that the 5G WiFi network adopts brand new wave band frequency and standard, the frequency band is 5GHz, the production is based on the technical standard of IEEE802.11ac, and the bidirectional speed is obviously improved.

Modulation and coding strategy (modulation and coding scheme, MCS): the terminal device may configure a network transmission rate of the wireless network by negotiating an MCS with an access point of the accessed wireless network. The MCS negotiated by the terminal device with the access point of the accessed wireless network may determine a network transmission rate of the wireless network, that is, the network transmission rate of the wireless network accessed by the terminal device may depend on the MCS negotiated with the access point of the wireless network.

Currently, the configuration of the terminal device to the network transmission rate of the wireless network may be implemented through an MCS index value. The MCS modulation coding table is a basis for configuring a network transmission rate of the wireless network, and includes a plurality of MCS index values and a network transmission rate corresponding to each MCS index value. For example, the plurality of MCS index values in the MCS modulation coding table may include MCS0 to MCS11. In addition, under different network systems, the range of the MCS which can be negotiated by the terminal equipment and the access point of the connected wireless network is different. For example, in a 2.4G WiFi network, an index value of MCS that can be negotiated by the terminal device and an access point of an accessed wireless network is MCS0 to MCS7; under the 5G WiFi network, the index value of the MCS which can be negotiated by the terminal equipment and the access point of the accessed wireless network is MCS 0-MCS 11. In general, the larger the index value of the MCS, the higher its corresponding network transmission rate.

Next, an application scenario related to the data transmission method provided by the embodiment of the present application is described.

Referring to fig. 1, fig. 1 is a block diagram of a terminal device according to an embodiment of the present application. As shown in fig. 1, the terminal device generally includes an antenna 1, a wireless communication module 10, and a processor 20, the wireless communication module 10 being coupled with the antenna 1 so that the terminal device can communicate with a network and other devices through wireless communication technology. For example, the terminal device may be connected to a wireless network through the wireless communication module 10 and the antenna 1, i.e., establish a network connection with the wireless network in order to receive or transmit information through the wireless network. After the terminal device is connected to the wireless network through the wireless communication module 10 and the antenna 1, the wireless communication module 10 may use a data transmission interface protocol to perform data transmission with the processor 20, for example, use PCIe protocol as shown in fig. 1.

For example, the wireless communication module 10 receives electromagnetic waves via the antenna 1, modulates the electromagnetic wave signals, filters the electromagnetic wave signals, and transmits the processed signals to the processor 20 using a data transmission interface protocol such as PCIe protocol. The wireless communication module 10 may also receive the signal to be sent from the processor 20 by using a data transmission interface protocol such as PCIe protocol, frequency modulate, amplify, and convert the signal to electromagnetic wave through the antenna 1 to radiate. By way of example, the wireless communication module 10 may be a wireless local area network (wireless local area network, WLAN) module.

As described in the background art, at present, after the terminal device accesses the wireless network through the wireless communication module 10, no matter what network system the wireless network is accessing, the wireless communication module 10 and the processor 20 all adopt a preset fixed data transmission interface protocol to perform data transmission, for example, adopt a fixed pcie1.0 protocol or a pcie2.0 protocol to perform data transmission. The technical solution of adopting a fixed data transmission interface protocol to perform data transmission between the wireless communication module 10 and the processor 20 has a certain limitation, and has low flexibility, and may not meet the data transmission requirement, for example, the data transmission rate and the electromagnetic interference (electromagnetic interference, EMI) performance may not be compatible.

For example, a data signal transmitted by adopting a fixed data transmission interface protocol may generate stronger interference noise in an operating frequency band of an accessed wireless network, and the generated interference noise may affect the receiving sensitivity of a wireless network module, further affect the throughput rate of the wireless network, so that the throughput rate of the wireless network is reduced, which intuitively represents that the video playing is blocked, the loading is slow, the file downloading is slow, and the like, and seriously affects the internet surfing experience of a user.

Referring to fig. 1, taking an example that a terminal device accesses a 2.4G WiFi network through a wireless communication module 10 and an antenna 1, after the terminal device accesses the 2.4G WiFi network, if a pcie2.0 protocol or a pcie3.0 protocol is adopted between the wireless communication module 10 and a processor 20 for data transmission, a transmitted data signal may generate stronger interference noise in an operating frequency band (2.400 GHz-2.4835 GHz) of the 2.4G WiFi network. If the antenna 1 receives the PCIe noise signal generated by the data transmission between the wireless communication module 10 and the processor 20, the throughput rate of the 2.4G WiFi network is reduced, which intuitively appears as network blocking, and affects the internet surfing experience of the user. This problem is particularly pronounced in the case of WiFi signals that are weak.

Referring to fig. 2, fig. 2 is a spectrum diagram of data noise generated by data transmission between a wireless communication module and a processor under different PCIe protocols under the same test environment according to an embodiment of the present application. The horizontal axis of the coordinate axis shown in fig. 2 represents the frequency of the generated data signal noise, and the vertical axis represents the power of the generated data signal noise, which may indicate the data signal noise strength. As shown in fig. 2, when the pcie2.0 protocol or the pcie3.0 protocol is adopted between the wireless communication module and the processor to perform data transmission, interference noise generated by the transmitted data signal in the frequency band of 2.4 GHz-2.5 GHz is strong, so that strong interference noise can be generated in the working frequency band of the 2.4G WiFi network, resulting in a decrease in throughput rate of the 2.4G WiFi network. Under the condition that PCIE1.0 protocol is adopted between the wireless communication module and the processor for data transmission, the interference noise generated by the transmitted data signals in the frequency band of 2.4 GHz-2.5 GHz is weak, so that stronger interference noise cannot be generated in the working frequency band of the 2.4G WiFi network, and the throughput rate of the 2.4G WiFi network is influenced.

Therefore, in the case that the terminal device accesses the 2.4G WiFi network, if the data transmission is performed between the wireless communication module and the processor by adopting the pcie2.0 protocol or the pcie3.0 protocol with fixed configuration, the transmitted data signal will generate stronger interference noise in the working frequency band of the 2.4G WiFi network, and interfere with the receiving sensitivity of the wireless network module, thereby causing the throughput rate of the 2.4GWiFi network to be reduced, causing network jamming and affecting the user experience.

In the related art, interference noise generated by data signals transmitted between a wireless communication module and a processor can be reduced by configuring filtering components such as common-mode inductance or capacitance in a data signal wiring network of a terminal device or configuring shielding materials such as conductive foam or wave-absorbing materials. But this way increases the technical and material costs of the terminal device.

In order to improve flexibility of data transmission between a wireless communication module and a processor, the embodiment of the application provides a method for data transmission between a data transmission interface protocol matched with a network system and the wireless communication module by the processor according to the detection result of the wireless communication module, wherein the wireless communication module detects the network system of the wireless network accessed by the terminal device firstly and feeds back the detection result to the processor after the terminal device is accessed to the wireless network.

The method can ensure that the data transmission interface protocol adopted by the data transmission between the wireless communication module and the processor is matched with the network system of the wireless network accessed by the terminal equipment, so that the adopted data transmission interface protocol can meet the data transmission requirement of the access network system, for example, the adopted data transmission interface protocol can be ensured to be capable of considering the EMI performance and the transmission rate. Moreover, the method can save the technical cost and the material cost of the terminal equipment.

For example, after the terminal device accesses the wireless network, if the wireless communication module detects that the network system of the wireless network accessed by the terminal device is a 2.4G WiFi network, the processor selects the pcie1.0 protocol and the wireless communication module to perform data transmission according to the detection result of the wireless communication module. If the wireless communication module detects that the network system of the wireless network accessed by the terminal equipment is a 5G WiFi network, the processor selects other PCIe protocols such as PCIE2.0 protocol or PCIE3.0 protocol and the like to perform data transmission with the wireless communication module according to the detection result of the wireless communication module. Therefore, the problem that data signal noise generated under the PCIE2.0 protocol or the PCIE3.0 protocol interferes with the 2.4G WiFi network can be avoided, the throughput rate of the 2.4G WiFi network is improved, and user experience is further improved. In addition, under the condition that the data signal noise generated under the PCIE2.0 protocol or the PCIE3.0 protocol has little influence on the 5G WiFi network, the PCIE2.0 protocol or the PCIE3.0 protocol is selected through negotiation to perform data transmission, so that higher data transmission rate can be ensured. The technical scheme for selecting the matched PCIe protocol to carry out data transmission according to the network mode negotiation can give consideration to the network transmission rate and the EMI performance.

In addition, in order to improve the flexibility of data transmission between the wireless communication module and the processor, the embodiment of the application also provides a method that after the terminal equipment is accessed to the wireless network, the wireless communication module detects the MCS negotiated by the terminal equipment and the access point of the wireless network, then feeds back the detection result to the processor, and the processor selects a data transmission interface protocol matched with the detected MCS according to the detection result to perform data transmission with the processor. Because the MCS negotiated by the terminal device and the access point of the wireless network is usually different according to the different network modes of the accessed wireless network, the data transmission is performed by selecting the data transmission interface protocol matched with the detected MCS and the wireless communication module, so that the selected data transmission interface protocol can be ensured to be matched with the network mode corresponding to the detected MCS, and the adopted data transmission interface protocol can meet the data transmission requirement of the connected network mode, such as considering the EMI performance and the transmission rate.

The network transmission rate (throughput rate) of the wireless network depends on the MCS negotiated by the terminal equipment on one hand, and is matched with the data transmission rate between the wireless communication module and the processor on the other hand.

It should be noted that, the data transmission method provided by the embodiment of the present application may be applied to a terminal device configured with multiple antennas, in addition to the terminal device configured with a single antenna shown in fig. 1. A terminal device configured with a single antenna supports only a single input single output (simple input simple output, SISO) function, while a terminal device supporting multiple antennas supports both SISO and multiple input multiple output (multiple input multiple output, MIMO) functions. Referring to fig. 3, fig. 3 is a schematic structural diagram of another terminal device according to an embodiment of the present application. As shown in fig. 3, the terminal device generally includes an antenna 1, an antenna 2, a wireless communication module 10, and a processor 20. The antennas 1 and 2 are used for transmitting and receiving electromagnetic wave signals. Each antenna may be used to cover a single or multiple communication bands. Different antennas may also be multiplexed to improve the utilization of the antennas.

Next, a data transmission method provided by an embodiment of the present application will be described in detail with reference to fig. 6.

Fig. 6 is a flowchart of a data transmission method according to an embodiment of the present application, where the method is applied to a terminal device, and the terminal device includes a wireless communication module and a processor, and as shown in fig. 6, the method includes the following steps:

Step 601: the wireless communication module detects that the terminal equipment accesses the wireless network.

The terminal device may establish a wireless network connection through the wireless communication module, thereby connecting to the wireless network, i.e. accessing the wireless network. For example, the terminal device may send a connection request to an Access Point (AP) of the wireless network through the wireless communication module, and access the wireless network through the access point.

Moreover, the terminal device can establish connection with wireless networks of different network systems, so as to access the wireless networks of different network systems. For example, the terminal device may select to access one of the wireless networks preferentially according to the network quality of the plurality of wireless networks that can be accessed. The network system of the wireless network refers to the type of the wireless network, that is, the terminal device may be connected to different types of wireless networks through the wireless communication module.

As an example, the wireless network may be a WiFi network, such as a 2.4G WiFi network or a 5G WiFi network, or may be a WiFi network with other network systems, which is not limited in the embodiment of the present application.

As an example, the wireless communication module performs a handshake with the processor if it detects that the terminal device accesses the wireless network, to establish a connection with the processor through the handshake for subsequent data transmission through the established connection.

The process in which the wireless communication module handshakes with the processor may be referred to as a heartbeat. In one possible implementation, the wireless communication module may perform a handshake after detecting that the terminal device is connected to the wireless network through the wireless communication module, and then the handshake is not performed again if the wireless communication module is normally connected to the processor. In another possible implementation manner, in order to ensure that the service logic can perform correctly, a timed handshake between the wireless communication module and the processor, that is, a handshake is performed every preset time period.

As one example, the handshake process includes: the wireless communication module sends heartbeat information to the processor, the processor returns a corresponding message packet immediately after receiving the heartbeat information, and the wireless communication module completes a complete handshake after receiving the corresponding message packet. Or the processor sends heartbeat information to the wireless communication module, the wireless communication module returns a corresponding message packet immediately after receiving the heartbeat information, and the processor completes a complete handshake after receiving the corresponding message packet.

In addition, the terminal device can also judge whether the heartbeat of the wireless communication module is normal according to whether the handshake is successful and the times of success, so that relevant service logic and error processing can be carried out.

Step 602: the wireless communication module detects a network system of the wireless network.

The network system of the wireless network at least comprises a first network system and a second network system, and the first network system and the second network system are different. Of course, the network system of the wireless network may also include more different network systems, such as a third network system, a fourth network system, and so on, which are different from the foregoing network systems.

As an example, the first network system is a first WiFi network, the second network system is a second WiFi network, and the working frequency bands of the first WiFi network and the second WiFi network are different.

For example, the first WiFi network is a 2.4G WiFi network and the second WiFi network is a 5G WiFi network. A 2.4G WiFi network generally refers to a WiFi network with a frequency band between 2.400GHz and 2.4835 GHz. A 5G WiFi network generally refers to a WiFi network with a frequency band of 5 GHz. Of course, the first WiFi network and the second WiFi network may also be WiFi networks in other working frequency bands, which is not limited in the embodiment of the present application.

As an example, the wireless communication module may acquire network system information of a wireless network accessed by the terminal device, and determine a network system of the wireless network according to the network system information of the wireless network. The network system information of the wireless network is used for indicating the network system of the wireless network.

In one possible implementation manner, the wireless communication module may capture a data packet from the accessed wireless network through a wireless network capturing program, and analyze the captured data packet to obtain network system information of the wireless network from the captured data packet. Of course, other manners may be used to obtain network system information of the wireless network, which is not limited by the embodiment of the present application.

It should be noted that, the wireless communication module may configure the function of detecting the network system of the wireless network accessed by the terminal device in advance, so as to actively detect the network system of the wireless network after detecting that the terminal device is accessed to the wireless network, and then feed back the detection result to the processor. In addition, the wireless communication module may also detect the network system of the wireless network accessed by the terminal device under the control of the processor, that is, the processor controls the wireless communication module to detect the network system of the wireless network accessed by the terminal device, and then obtain the detection result of the wireless communication module.

Step 603: the wireless communication module sends the detection result to the processor.

The detection result comprises network type information of a wireless network accessed by the terminal equipment.

That is, after detecting the network system of the wireless network to which the terminal device accesses, the wireless communication module may feed back the detected network system to the processor.

As one example, the wireless communication module may send the detection result to the processor during a handshake with the processor. Therefore, the wireless communication module can detect the network type of the wireless network accessed by the terminal equipment before establishing connection with the processor, and feeds back the detected network type to the processor in the process of establishing connection with the processor, so that the processor can directly adopt a data transmission interface protocol matched with the network type to carry out data transmission with the wireless communication module after establishing connection with the wireless communication module, and the data transmission efficiency can be improved.

It should be noted that the wireless communication module may handshake with the processor before step 603. For example, a handshake with the processor is performed after step 601 or step 602.

Step 604: and the processor receives the detection result, and selects a data transmission interface protocol matched with the network system to transmit data with the wireless communication module according to the detection result.

The data transmission interface protocol matched with the network system refers to the data transmission interface protocol matched with the network system of the accessed wireless network, namely, the data transmission interface protocol capable of meeting the data transmission requirement under the network system of the accessed wireless network. For example, the data transmission interface protocol matched with the network system can be a data transmission interface protocol capable of considering the EMI performance and the data transmission rate of the accessed wireless network.

As one example, the processor may negotiate with the wireless communication module to select a data transfer interface protocol that matches the network format for data transfer. For example, compared with the technical scheme of adopting a fixed data transmission interface protocol to perform data transmission with a processor in the related art, in the embodiment of the present application, a target negotiation mechanism may be configured in advance for the processor and the wireless communication module, where the target negotiation mechanism refers to a mechanism for negotiating and selecting the data transmission interface protocol between the processor and the wireless communication module. After receiving the network system of the wireless network fed back by the wireless communication module, the processor can adopt the target negotiation mechanism to negotiate with the wireless communication module to select a data transmission interface protocol matched with the network system for data transmission.

The network system of the wireless network at least comprises a first network system and a second network system, the data transmission interface protocol matched with the first network system is a first data transmission interface protocol, the data transmission interface protocol matched with the second network system is a second data transmission interface protocol, and the first data transmission interface protocol and the second data transmission interface protocol are different.

For example, according to the detection result, selecting the data transmission interface protocol matched with the network system to perform data transmission with the wireless communication module may include: if the network system of the wireless network is a first network system, selecting a first data transmission interface protocol matched with the first network system to transmit data with the wireless communication module; and if the network system of the wireless network is a second network system, selecting a second data transmission interface protocol matched with the second network system to transmit data with the wireless communication module.

The wireless network may be a WiFi network or other wireless network. The first data transmission interface protocol and the second data transmission interface protocol may be PCIe protocols, protocols upgraded in PCIe protocols, or other data transmission interface protocols, which are not limited by the embodiments of the present application.

As an example, the first network system is a first WiFi network, and the first data transmission interface protocol is a first PCIe protocol; the second network system is a second WiFi network, and the second data transmission interface protocol is a second PCIe protocol. The data transmission rates corresponding to the first PCIe protocol and the second PCIe protocol are different.

Illustratively, the first WiFi network is a 2.4G WiFi network, and the first PCIe protocol is a first generation PCIe protocol; the second WiFi network is a 5G WiFi network, and the second PCIe protocol is a second generation PCIe protocol or a third generation PCIe protocol.

As an example, if the network system of the wireless network is a 2.4G WiFi network, the pcie1.0 protocol is selected to perform data transmission with the wireless communication module. If the network system of the wireless network is a 5G WiFi network, selecting a PCIE2.0 protocol or a PCIE3.0 protocol to perform data transmission with the wireless communication module.

In the embodiment of the application, after the terminal equipment is accessed to the wireless network, the wireless communication module firstly detects the network system of the wireless network accessed by the terminal equipment, then the detection result is fed back to the processor, and the processor selects a data transmission interface protocol matched with the network system to carry out data transmission with the wireless communication module according to the detection result. Therefore, the flexibility of data transmission between the wireless communication module and the processor can be improved, the data transmission interface protocol adopted for data transmission between the wireless communication module and the processor is ensured to be matched with the network system of the wireless network accessed by the terminal equipment, so that the adopted data transmission interface protocol can meet the data transmission requirement of the accessed network system, for example, the adopted data transmission interface protocol can be ensured to be capable of considering the EMI performance and the data transmission rate under the wireless network.

Next, in conjunction with the technical solution described in fig. 6, the data transmission method provided by the embodiment of the present application is illustrated by taking the first WiFi network as a 2.4G WiFi network, the first PCIe protocol as a PCIe1.0 protocol, the second WiFi network as a 5G WiFi network, and the second PCIe protocol as a PCIe2.0 protocol or a PCIe3.0 protocol as an example.

Fig. 7 is a flowchart of another data transmission method provided in an embodiment of the present application, where the method is applied to a terminal device, and the terminal device includes a wireless communication module and a processor, as shown in fig. 1, and the method includes the following steps:

step 701: the wireless communication module detects that the terminal equipment accesses the wireless network.

Step 702: the wireless communication module detects a network system of the wireless network.

Step 703: the wireless communication module performs a handshake with the processor.

After detecting that the terminal device accesses the wireless network, the wireless communication module may handshake with the processor to establish a connection with the processor in order to be able to send data received from the wireless network to the processor or to send data from the processor to the wireless network.

The handshake between the wireless communication module and the processor may refer to the description of step 601 in the embodiment of fig. 6, which is not repeated herein.

Step 704: the wireless communication module sends the detection result to the processor in the process of handshake with the processor.

In the embodiment of the application, the wireless communication module can detect the network system of the wireless network in the process of handshaking with the processor, and negotiate with the processor to select a data transmission interface protocol matched with the network system to transmit data with the processor.

Therefore, the wireless communication module can negotiate with the processor to select a proper data transmission interface protocol before successfully establishing connection with the processor, and can directly adopt the selected data transmission interface protocol to carry out data transmission after successfully establishing connection subsequently, so that the data transmission efficiency can be improved.

For example, the wireless communication module may acquire network system information of the wireless network in a process of handshaking with the processor, and determine a network system of the wireless network according to the network system information of the wireless network.

In one possible implementation manner, the wireless communication module may capture a data packet from the wireless network through a wireless network capturing program, and parse the captured data packet to obtain network system information of the wireless network from the captured data packet. Of course, other manners may be used to obtain network system information of the wireless network, which is not limited by the embodiment of the present application.

Step 705: and the processor receives the detection result and judges whether the network system of the wireless network is a 2.4G WiFi network or not.

Step 706: if the network system of the wireless network is a 2.4G WiFi network, the processor and the wireless communication module negotiate to select PCIE1.0 protocol to perform data transmission with the wireless communication module.

Step 707: if the network system of the wireless network is not 2.4GWiFi, the processor judges whether the network system of the wireless network is a 5G WiFi network.

Step 708: if the network system of the wireless network is a 5G WiFi network, the processor and the wireless communication module negotiate to select PCIE2.0 protocol or PCIE3.0 protocol to perform data transmission with the wireless communication module.

As an example, considering that the data transmission rate corresponding to the pcie3.0 protocol is greater than the data transmission rate corresponding to the pcie2.0 protocol, if the network system of the wireless network is a 5G WiFi network, the pcie3.0 protocol may be selected for data transmission.

As another example, considering that, in the case where the network system of the wireless network is a 5G WiFi network, the intensity of interference noise generated by data transmission using the pcie2.0 protocol is lower than the intensity of interference noise generated by data transmission using the pcie3.0 protocol, if the network system of the wireless network is a 5G WiFi network, the pcie2.0 protocol may be selected for data transmission.

As another example, to achieve both data transmission rate and EMI performance, if the network system of the wireless network is a 5G WiFi network, the pcie3.0 protocol may be selected for data transmission, then the strength of interference noise generated by using the pcie3.0 protocol for data transmission is detected, and if the strength of the generated interference noise is greater than the strength threshold, then the pcie2.0 protocol is selected for data transmission.

It should be understood that the processor may also determine whether the network system of the wireless network is a 5G WiFi network, if so, select pcie2.0 protocol or pcie3.0 protocol to perform data transmission with the wireless communication module, and if not, determine whether the network system is a 2.4G WiFi network. If yes, selecting PCIE1.0 protocol and the wireless communication module to transmit data. The embodiment of the present application does not limit the sequence of step 705 and step 707.

In the embodiment of the application, after the terminal equipment accesses the wireless network, the wireless communication module firstly detects the network system of the accessed wireless network and feeds back the detection result to the processor. If the processor judges that the wireless network accessed by the terminal equipment is the 2.4G WiFi network according to the detection result, the PCIE1.0 protocol and the wireless communication module are selected for data transmission, so that the problem that data signal noise generated under the PCIE2.0 protocol and the PCIE3.0 protocol interferes with the 2.4G WiFi network can be avoided, the throughput rate of the 2.4GWiFi network is improved, and further user experience is improved. If the wireless network accessed by the terminal equipment is judged to be a 5G WiFi network, selecting the PCIE2.0 protocol or the PCIE3.0 protocol to carry out data transmission with the wireless communication module, so that higher data transmission rate can be ensured under the condition that the data signal noise generated under the PCIE2.0 protocol or the PCIE3.0 protocol has little influence on the 5G WiFi network. The technical scheme for selecting the matched PCIe protocol to carry out data transmission according to the network system can give consideration to the EMI performance and the data transmission rate.

Fig. 8 is a flowchart of yet another data transmission method according to an embodiment of the present application, where the method is applied to a terminal device, and the terminal device includes a wireless communication module and a processor, as shown in fig. 8, and the method includes the following steps:

step 801: the wireless communication module detects that the terminal equipment accesses the wireless network.

It should be noted that, for the specific implementation manner of step 801, reference may be made to step 601, and the embodiments of the present application are not described herein.

Step 802: the wireless communication module detects the MCS negotiated by the terminal device with the access point of the wireless network.

As one example, the wireless communication module may detect an index value of an MCS negotiated by the terminal device with an access point of the wireless network, and determine the MCS negotiated by the terminal device with the access point of the wireless network according to the index value.

In one possible implementation, the wireless communication module may capture a data packet from the wireless network through a wireless network capturing procedure, and parse the captured data packet to obtain an index value of an MCS negotiated by the terminal device and an access point of the wireless network from the captured data packet. Of course, other manners may be adopted to obtain the index value of the MCS negotiated by the terminal device and the access point of the wireless network, which is not limited in the embodiment of the present application.

It should be noted that, the wireless communication module may configure the function of detecting the MCS negotiated by the terminal device and the access point in advance, so as to actively detect the MCS negotiated by the terminal device and the access point after detecting that the terminal device accesses the wireless network, and then feed back the detection result to the processor. In addition, the wireless communication module may also detect the MCS negotiated by the terminal device and the access point under the control of the processor, that is, the processor controls the wireless communication module to detect the MCS negotiated by the terminal device and the access point, and then obtains the detection result of the wireless communication module.

Step 803: the wireless communication module sends the detection result to the processor.

The detection result includes MCS information negotiated by the terminal device and the access point, for example, the MCS information may be an index value of the MCS, etc.

That is, the wireless communication module may feed back the detected MCS to the processor after detecting the MCS negotiated with the access point by the terminal device.

As one example, the wireless communication module may send the detection result to the processor during a handshake with the processor. Therefore, before the wireless communication module establishes connection with the processor, the MCS negotiated by the terminal equipment and the access point can be detected, and in the process of establishing connection with the processor, the detection result is fed back to the processor, so that the processor can directly adopt a data transmission interface protocol matched with the MCS negotiated by the terminal equipment to carry out data transmission with the wireless communication module after establishing connection with the wireless communication module, and the data transmission efficiency can be improved.

It should be noted that the wireless communication module may handshake with the processor before step 803. For example, a handshake with the processor is performed after step 801 or step 802.

Step 804: and the processor receives the detection result, and selects a data transmission interface protocol matched with the MCS to perform data transmission with the wireless communication module according to the detection result.

The data transmission interface protocol matched with the MCS refers to a data transmission interface protocol which is matched with the negotiated MCS and can meet the data transmission requirement under the negotiated MCS. For example, the data transmission interface protocol matched with the MCS may be a data transmission interface protocol capable of considering EMI performance and data transmission rate under an accessed wireless network.

In addition, because the range of the MCS negotiated by the terminal device and the access point of the wireless network is usually different according to the different network modes of the accessed wireless network, the data transmission is performed with the wireless communication module by selecting the data transmission interface protocol matched with the negotiated MCS, and the selected data transmission interface protocol can be ensured to be matched with the network mode corresponding to the negotiated MCS, so that the adopted data transmission interface protocol can meet the data transmission requirement under the accessed network mode.

As one example, the processor may negotiate with the wireless communication module to select a data transmission interface protocol matching the MCS for data transmission. For example, a target negotiation mechanism may be configured in advance for the processor and the wireless communication module, the target negotiation mechanism referring to a mechanism for negotiating a data transmission interface protocol between the processor and the wireless communication module. After receiving the MCS negotiated by the terminal device and the access point and fed back by the wireless communication module, the processor may use the target negotiation mechanism to negotiate with the wireless communication module to select a data transmission interface protocol matching the MCS for data transmission.

As one example, multiple MCS sets may be preconfigured, and when the MCS negotiated by the terminal device and the access point of the wireless network are located in different MCS sets, the data transmission interface protocol matched thereto is different.

For example, the plurality of MCS sets includes a first MCS set and a second MCS set, and an intersection of the first MCS set and the second MCS set is null. If the MCS belongs to the first MCS set, the data transmission interface protocol matched with the MCS is the first data transmission interface protocol, and if the MCS belongs to the second MCS set, the data transmission interface protocol matched with the MCS is the second data transmission interface protocol. Wherein the first data transfer interface protocol and the second data transfer interface protocol are different.

As one example, if the negotiated MCS belongs to the first MCS set, the processor selects the first data transmission interface protocol for data transmission with the wireless communication module. And if the negotiated MCS belongs to the second MCS set, the processor selects a second data transmission interface protocol to perform data transmission with the wireless communication module.

As one example, the wireless communication module may obtain an index value of an MCS negotiated by the terminal device with an access point of the wireless network; if the index value belongs to the first MCS index value set, determining that the MCS belongs to the first MCS set; if the index value belongs to the second MCS index value set, determining that the MCS belongs to the second MCS set.

Illustratively, the first set of MCS index values is MCS0-MCS7 and the second set of MCS index values is MCS8-MCS11. Of course, the first MCS index value set and the second MCS index value set may be other index value sets, which is not limited in the embodiment of the present application.

Illustratively, the first data transmission interface protocol is a pcie1.0 protocol, and the second data transmission interface protocol is a pcie2.0 protocol or a pcie3.0 protocol. Of course, the first data transmission interface protocol and the second data transmission interface protocol may be other PCIe protocols, which is not limited by the embodiment of the present application.

Because under the 2.4G WiFi network, the index value of the MCS which can be negotiated by the terminal equipment and the access point of the connected wireless network is MCS0-MCS7, and under the 5G WiFi network, the index value of the MCS which can be negotiated by the terminal equipment and the access point of the connected wireless network is MCS0-MCS 11. Therefore, if the index value of the negotiated MCS is located between MCS0 and MCS7, it indicates that the accessed wireless network is a 2.4G WiFi network or a 5G WiFi network, and if the index value of the negotiated MCS is located between MCS8 and MCS11, it indicates that the accessed wireless network is a 5G WiFi network.

In the embodiment of the application, after the terminal equipment is accessed to the wireless network, the wireless communication module can detect the MCS negotiated by the terminal equipment and the access point of the accessed wireless network, and feed back the detection result to the processor, and the processor selects a data transmission interface protocol matched with the MCS according to the detection result to perform data transmission with the processor. Because the MCS negotiated by the terminal device and the access point of the wireless network is related to the network system of the wireless network, and the network transmission rate of the wireless network can be determined to a certain extent, the processor detects the MCS negotiated by the terminal device and the access point of the wireless network through the wireless communication module, then selects the data transmission interface protocol matched with the MCS negotiated by the terminal device to carry out data transmission with the wireless communication module, can ensure the adaptation of the selected data transmission interface protocol and the MCS and the network system adaptation corresponding to the MCS, realizes the dynamic association of the network transmission rate-MCS-data transmission interface protocol of the wireless network, improves the flexibility of data transmission between the wireless communication module and the processor, and can consider the network transmission rate and the EMI performance.

Next, in conjunction with the technical solution described in fig. 8, taking the first MCS index value set as MCS0 to MCS7, the first PCIe protocol as PCIe1.0 protocol, the second MCS index value set as MCS8 to MCS11, and the second PCIe protocol as PCIe2.0 protocol or PCIe3.0 protocol as an example, the data transmission method provided by the embodiment of the present application is illustrated.

Fig. 9 is a flowchart of yet another data transmission method according to an embodiment of the present application, where the method is applied to a terminal device, and the terminal device includes a wireless communication module and a processor, as shown in fig. 9, and the method includes the following steps:

Step 901: the wireless communication module detects that the terminal equipment accesses the wireless network.

Step 902: the wireless communication module detects an index value of the MCS negotiated by the terminal device and an access point of the wireless network.

Step 903: the wireless communication module sends the detection result to the processor.

Step 904: and processing to receive the detection result and judging whether the index value of the negotiated MCS belongs to MCS 0-MCS 7.

In the embodiment of the application, two MCS index value sets, namely MCS 0-MCS 7 and MCS 8-MCS 11, can be preset. Then, after detecting the index value of the MCS negotiated by the terminal device and the access point of the wireless network, it is determined whether the index value of the negotiated MCS is located in the two MCS index value sets.

It should be noted that, in the embodiment of the present application, it is only described by taking as an example whether the index value of the negotiated MCS belongs to MCS0 to MCS7, and if not, whether the index value of the negotiated MCS belongs to MCS8 to MCS 11. It should be understood that it is also possible to determine whether the index value of the negotiated MCS belongs to MCS8 to MCS11 first, and if not, determine whether the index value of the negotiated MCS belongs to MCS0 to MCS7. The embodiment of the present application does not limit the sequence of step 903 and step 905.

Step 905: if the index value of the negotiated MCS belongs to MCS 0-MCS 7, the processor and the wireless communication module negotiate to select PCIE1.0 protocol for data transmission with the wireless communication module.

Because under the 2.4G WiFi network, the index value of the MCS which can be negotiated by the terminal equipment and the access point of the connected wireless network is MCS0-MCS7, and under the 5G WiFi network, the index value of the MCS which can be negotiated by the terminal equipment and the access point of the connected wireless network is MCS0-MCS 11. Therefore, if the index value of the negotiated MCS belongs to MCS0-MCS7, it is indicated that the connected wireless network is a 2.4G WiFi network or a 5G WiFi network.

When the index value of the negotiated MCS belongs to MCS 0-MCS 7, negotiating and selecting the PCIE1.0 protocol with the processor to perform data transmission, so that the problem that data signal noise generated under the PCIE2.0 protocol and the PCIE3.0 protocol interferes with the 2.4G WiFi network can be avoided under the condition that the connected network is the 2.4G WiFi network, the throughput rate of the 2.4G WiFi network is improved, and further the user experience is improved.

Step 906: if the index value of the negotiated MCS does not belong to MCS 0-MCS 7, the processor determines whether the index value of the negotiated MCS belongs to MCS 8-MCS 11.

Step 907: if the index value of the negotiated MCS belongs to MCS 8-MCS 11, the processor and the wireless communication module negotiate to select PCIE2.0 protocol or PCIE3.0 to perform data transmission with the wireless communication module.

If the index value of the negotiated MCS belongs to MCS 8-MCS 11, the connected wireless network is a 5G WiFi network. When the index value of the negotiated MCS belongs to MCS 8-MCS 11, negotiating and selecting PCIE2.0 protocol or PCIE3.0 with the processor to perform data transmission, not only can ensure higher data transmission rate under the condition that the influence of data signal noise generated under the PCIE2.0 protocol or PCIE3.0 protocol on a 5GWiFi network is not great, but also can perform data transmission with the processor by adopting a PCIe protocol adapted to the higher network transmission rate when the network transmission rate is higher under the 5G WiFi network.

Step 908: if the wireless communication module detects that the terminal device renegotiates the MCS with the access point, the step is skipped to step 902, and the index value of the renegotiated MCS is fed back to the processor, so that the processor and the wireless communication module negotiate to select a data transmission interface protocol matched with the renegotiated MCS for data transmission.

That is, if the wireless network performs speed re-regulation, the processor may detect an index value of the MCS renegotiated by the terminal device and the access point of the wireless network through the wireless communication module, and negotiate with the wireless communication module to select a data transmission interface protocol matching the renegotiated MCS for data transmission.

In the embodiment of the application, after the terminal equipment is accessed to the wireless network, the wireless communication module can detect the index value of the MCS negotiated by the terminal equipment and the access point of the wireless network and send the detection result to the processor. If the index value of the negotiated MCS belongs to MCS 0-MCS 7, the processor and the wireless communication module negotiate to select PCIE1.0 protocol for data transmission, so that the problem that data signal noise generated under the PCIE2.0 protocol and the PCIE3.0 protocol interferes with the 2.4G WiFi network can be avoided under the condition that the accessed wireless network is the 2.4G WiFi network, the throughput rate of the 2.4G WiFi network is improved, and the user experience is further improved. If the index value of the negotiated MCS belongs to MCS 8-MCS 11, the processor negotiates with the wireless communication module to select PCIE2.0 protocol or PCIE3.0 for data transmission, so that higher data transmission rate can be ensured under the condition that the influence of data signal noise generated under the PCIE2.0 protocol or PCIE3.0 protocol on the 5G WiFi network is not great, and the PCIe protocol adapted to the higher network transmission rate can be adopted for data transmission when the network transmission rate under the 5G WiFi network is higher. In summary, when the terminal device performs wireless network communication, dynamic association of network transmission rate-MCS-data transmission interface protocol of the wireless network can be realized, and EMI performance and transmission rate are considered.
