Description

Technical Field

[0001] The present invention is applicable to the field of wireless network technology, and in particular relates to a single-module multi-type WiFi connection switching method, system and related equipment. Background Art

[0002] WiFi P2P (Peer-to-Peer) is a protocol released by the WiFi Alliance. This protocol allows devices in a WiFi wireless network to connect to each other without going through a wireless router, and directly realizes point-to-point communication between two devices through the WiFi wireless network. The principle of this technology is similar to the communication method based on AP (access point). Devices that support WiFi P2P can transfer data to each other within the same group.

[0003] However, the WiFi P2P protocol is a complex and time-consuming process, which includes the basic steps of discovery, negotiation, and configuration. Different devices are prone to negotiation and configuration failures, or connection problems due to protocol compatibility. Related technologies have proposed a WiFi direct connection method to optimize the traditional WiFi device connection method, and implemented a device direct connection method that is different from the WiFi P2P protocol. Compared with WiFi P2P, WiFi direct connection can reduce the connection process and thus optimize the connection efficiency.

[0004] In addition, the prior art also has a method of using WiFi Softap to achieve data transmission within WiFi. WiFi Softap is a technology that implements AP functions through software. It can replace the AP in a wireless network, thereby reducing the cost of wireless networking. The wireless device finds the SSID of WiFi Softap and achieves direct device connection by entering PSK, thereby achieving data transmission.

[0005] Obviously, the WiFi P2P, WiFi Softap and WiFi direct connection methods in the above methods are different network protocols. Therefore, the network connections implemented using the above methods are not compatible with each other. It is difficult for the same device to use two connection methods for data transmission at the same time, which is inconvenient for users. Summary of the invention

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the steps of a method for switching multiple types of WiFi connections in a single module provided by an embodiment of the present invention. The method for switching multiple types of WiFi connections in a single module includes the following steps:

[0040] S101, initializing a WiFi module of a device and enabling the WiFi module;

[0041] S102, according to the WiFi module, enabling a first data connection based on the WiFi P2P protocol based on the first WiFi channel, and at the same time, enabling a second data connection based on the WiFi direct protocol based on the second WiFi channel, and enabling a third data connection based on the WiFi Softap based on the third WiFi channel;

[0042] S103: Based on a time-division multiplexing method, monitor the connection request on the first WiFi channel using the first data connection, monitor the connection request on the second WiFi channel using the second data connection, and monitor the connection request on the third WiFi channel using the third data connection;

[0043] S104, performing data transmission according to the result of the connection request monitoring of the first WiFi channel, the result of the connection request monitoring of the second WiFi channel, and the result of the connection request monitoring of the third WiFi channel, wherein:

[0044] 1041. When the first data connection monitors a connection request on the first WiFi channel, suspend the second data connection and the third data connection, and perform data transmission based on the first data connection with the device sending the connection request based on the WiFi module;

[0045] 1042. When the second data connection monitors a connection request on the second WiFi channel, suspend the first data connection and the third data connection, and perform data transmission based on the second data connection with the device sending the connection request based on the WiFi module;

[0046] 1043. When the third data connection monitors a connection request on the third WiFi channel, suspend the first data connection and the second data connection, and perform data transmission based on the third data connection with the device that sends the connection request based on the WiFi module.

[0047] After the above step S104, the single-module multi-type WiFi connection switching method further includes the following steps:

[0048] S105: After completing the data transmission of the first data connection, or completing the data transmission of the second data connection, or completing the data transmission of the third data connection based on the WiFi module, return to step S103.

[0049] Specifically, in step S103, when the second data connection is used to request monitoring on the second WiFi channel, the monitored data is preset action frame data, and the preset action frame data is based on the IEEE 802.11 format frame, wherein:

[0050] The packet header of the preset action frame data includes an organizational unique identifier for identifying a direct connection between the WiFi module and the device sending the connection request, and the data of the preset action frame data includes an action frame creation time, a length of data to be received, and a queuing time for transmission delay synchronization.

[0051] Correspondingly, in step 1042, when data transmission based on the second data connection is performed based on the WiFi module, the transmitted data is preset data frame data, and the preset data frame data is based on the IEEE 802.11 format frame, wherein:

[0052] The To DS and From DS field flags of the preset data frame data are set to 0, the packet header of the preset data frame data includes an organizational unique identifier (OUI) for identifying a direct connection between the WiFi module and the device sending the connection request, and the data of the preset data frame data includes a transmission number and communication data corresponding to the transmission number.

[0053] Specifically, please refer to Table 1 and Table 2, which are respectively the data packet fields of the preset action frame data and the preset data frame data provided in the embodiments of the present invention, and the preset action frame data and the preset data frame data are both implemented based on the IEEE802.11 format frame.

[0054] Table 1 Preset action frame data packet fields

[0055]

[0056] As shown in Table 1 above, the preset action frame data in the embodiment of the present invention uses a custom IEEE 802.11 action frame. Based on the protocol, an organizational unique identifier can be used to implement an IEEE802.11 frame with any payload during implementation. The action frame data implemented based on IEEE 802.11 in the embodiment of the present invention can extend a fixed-size header and multiple IE fields. The fixed header mainly includes static values, such as a specific BSSID, OUI, version and type; the IE consists of a 1-byte type field and a 2-byte length field, and the length field indicates the length of the subsequent data frame (the length of the data to be received). The two timestamps represent the creation time of the action frame. According to the timestamp, it can be determined whether the information contained in the action frame data is the latest (TTx, Target), as well as the actual transmission delay synchronization queuing time (TTx, PHY). The difference between the creation time and the queuing time is close to the transmission delay of the sending device, which can be used to achieve data synchronization during implementation.

[0057] Table 2 Preset data frame data packet fields

[0058]

[0059]

[0060] Similarly, the embodiment of the present invention uses IEEE 802.11 data frames for data transmission. Among them, the To DS and From DS flags in Framecontrol are set to 0, which means that in actual data transmission, these data frames will be directly addressed, and the three address fields are used for the destination, source and destination, and BSSID respectively. As shown in Table 2 above, the BSSID in the data frame data is always a fixed address, which is used to assign the WiFi module or the corresponding connected device with OUI; the LLC header contains different OUIs and protocol IDs in the SNAP part, and these IEs are part of the IEEE 802.11 standard; the data header mainly consists of a sequence of transmission protocol numbers and EtherType. It can be seen that, excluding the part of the protocol standard, the data header and the communication data (Data) actually transmitted constitute the data frame data in the embodiment of the present invention.

[0061] In the embodiment of the present invention, the device including the WiFi module serves as a receiving device, and after receiving the preset action frame data, establishes a data connection with a corresponding device that has sent the preset action frame data, thereby completing a direct connection interaction based on WiFi.

[0062] The sub-protocol matching transmission based on different types of WiFi transmission protocols (WiFi direct connection, WiFi Softap and P2P protocol) enables the device based on this method to be compatible with different types of WiFi connection requests. For the screen projection receiving device, the method of the embodiment of the present invention provides a variety of connection methods for screen projection. At the same time, different connection methods can be switched arbitrarily during use, which improves the convenience of users using screen projection. At the same time, the WiFi direct connection method in the above method reduces the discovery and negotiation process compared to the P2P protocol transmission, and improves the transmission efficiency of screen projection.

[0063] In the embodiment of the present invention, the first WiFi channel includes one WiFi channel, and the second WiFi channel includes at least one WiFi channel. It can be understood that in the embodiment of the present invention, the request data monitoring is performed in a time-division multiplexing manner, so the monitoring of the first WiFi channel and the second WiFi channel is performed by the WiFi module simultaneously on different channels. Such a design ensures that WiFi P2P, WiFi Softap or WiFi direct connection also have high real-time performance in a mutually compatible scenario (at the level of the same device completing different types of WiFi data transmission).

[0064] The beneficial effect achieved by the present invention is that a method capable of adaptively switching between WiFi direct connection, WiFi Softap and WiFiP2P connection is proposed. The method realizes multiple WiFi connection modes in different channels based on a single WiFi module, monitors external device connection requests in a time-division multiplexing manner, and realizes corresponding WiFi data direct connection, WiFi Softap, WiFiP2P data transmission according to the request type, and active switching after the transmission is completed. The device realized based on the method has better compatibility in WiFi connection type, realizes automatic protocol matching connection, and improves user experience.
