[0039] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0040] The transmitting end determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies whether the transmitting end supports out-of-order transmission of data frames;

[0041] Send the first data frame.

[0042] In the above embodiment, the transmitting end determines the first wireless frame, and identifies whether the transmitting end supports the out-of-order transmission of data frames through the first identification information in the first wireless frame, so that the receiving end can obtain information on whether the transmitting end supports the out-of-order transmission of data frames, that is, the transmitting end can give priority to transmitting business data with higher priority (for example, low-latency business data with larger serial numbers). Further, when the receiving end determines that both itself and the transmitting end support the out-of-order transmission of data frames, it can give priority to transmitting business data with higher priority with the transmitting end, thereby reducing transmission delay.

[0043] In combination with some embodiments of the first aspect, in some embodiments, the first identification information is carried in the media access control MAC (Media Access Control) capabilities field of the ultra-high reliability (UHR) capabilities information element of the first wireless frame.

[0044] In the above embodiment, the first identification information that can identify whether the transmitting end supports out-of-order transmission of data frames can be effectively carried in the first radio frame, so that the receiving end can effectively parse the first radio frame.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the first identification information is set to a first parameter value, identifying the sending end to indicate out-of-order transmission of the data frame.

[0046] In the above embodiment, by digitizing the first identification information, when the first identification information is set to the first parameter value, the identifier transmitter instructs the out-of-order transmission of the data frame, which can reduce the amount of transmission data required for the first wireless frame during transmission.

[0047] In combination with some embodiments of the first aspect, in some embodiments, a second radio frame is received, the second radio frame includes second identification information, and the second identification information identifies whether the receiving end supports out-of-order transmission of data frames.

[0048] In the above embodiment, the second wireless frame sent by the receiving end is received, and the second identification information in the second wireless frame is used to identify whether the receiving end supports the out-of-order transmission of data frames. This allows the sending end to obtain information about whether the receiving end supports the out-of-order transmission of data frames, that is, the receiving end can give priority to transmitting business data with higher priority (for example, low-latency business data with a larger serial number), and then when the sending end determines that both itself and the receiving end support the out-of-order transmission of data frames, it can give priority to transmitting business data with higher priority with the receiving end, thereby reducing transmission delay.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the second identification information is carried in a MAC capabilities field of a UHR capabilities information element of the second radio frame.

[0050] In the above embodiment, the first identification information that can identify whether the receiving end supports out-of-order transmission of data frames can be effectively carried in the second radio frame, so that the transmitting end can effectively parse the second radio frame.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the second identification information is set to a second parameter value, indicating that the receiving end indicates out-of-order transmission of the data frame.

[0052] In the above embodiment, by digitizing the second identification information, when the second identification information is set to the second parameter value, the identifier transmitter instructs the out-of-order transmission of the data frame, which can reduce the amount of transmission data required for the second wireless frame during transmission.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information identifies that the transmitting end supports out-of-order transmission of data frames, and the second identification information identifies that the receiving end supports out-of-order transmission of data frames, to determine the first data frame; wherein the first data frame includes third identification information, and the third identification information identifies a message number PN value range of the first data frame;

[0054] Send the first data frame.

[0055] In the above embodiment, the PN value range of the first data frame is identified by the third identification information in the first data frame, so that the receiving end of the first data frame can determine whether the transmission of the currently received first data frame is a valid out-of-order transmission based on the PN value range and the PN value of the first data frame received last time.

[0056] In combination with some embodiments of the first aspect, in some embodiments, the third identification information is carried in the MAC frame header position of the first data frame.

[0057] In the above embodiment, by carrying the third identification information in the MAC frame header of the first data frame, the receiving end of the first data frame can determine whether the transmission of the currently received first data frame is a valid out-of-order transmission based on the third identification information.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the PN value corresponds to a preset transmission identifier TID.

[0059] In the above embodiment, by making the PN value correspond to the TID, the receiving end of the first data frame can obtain the service type to which the first data frame belongs according to the PN value of the first data frame.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes: at least one of a probe request frame, an association request frame, and a reassociation request frame;

In the process of establishing an association between the transmitter and the receiver of the first wireless frame, or in the process of publishing or obtaining network information between the transmitter and the receiver of the first wireless frame, whether the transmitter supports out-of-order transmission of data frames can be identified through the first wireless frame.

[0063] In a second aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0064] The receiving end receives a first wireless frame, wherein the first wireless frame includes first identification information, and the first identification information identifies whether the transmitting end supports out-of-order transmission of data frames.

[0065] In the above embodiment, the first identification information in the first wireless frame is used to identify whether the sending end supports the out-of-order transmission of data frames, so that the receiving end can obtain information about whether the sending end supports the out-of-order transmission of data frames, that is, the sending end can give priority to transmitting business data with higher priority (for example, low-latency business data with larger serial numbers). Further, when the receiving end determines that both itself and the sending end support the out-of-order transmission of data frames, it can give priority to transmitting business data with higher priority with the sending end to reduce transmission delay.

[0066] In combination with some embodiments of the second aspect, in some embodiments, the first identification information is carried in a MAC capabilities field of a UHR capabilities information element of the first radio frame.

This allows the sending end to obtain information on whether the receiving end can support the out-of-order transmission of data frames, that is, the receiving end can give priority to transmitting business data with higher priority (for example, low-latency business data with larger serial numbers). Further, when the sending end determines that both itself and the receiving end support the out-of-order transmission of data frames, it can give priority to transmitting business data with higher priority with the receiving end, thereby reducing transmission delay.

[0075] In the above embodiment, the receiving end can identify the PN value range of the first data frame through the third identification information in the first data frame, so that the receiving end of the first data frame can determine whether the transmission of the currently received first data frame is a valid out-of-order transmission based on the PN value range and the PN value of the first data frame received last time.

[0076] In conjunction with some embodiments of the second aspect, in some embodiments, determining whether transmission of the first data frame is valid out-of-order transmission includes:

[0078] The difference between the PN value of the first data frame and the initial PN value is greater than the PN value range, and it is determined that the transmission of the first data frame is invalid and out-of-order transmission.

[0079] In the above embodiment, the receiving end can determine whether the transmission of the first data frame is a valid disordered transmission by determining the size relationship between the difference between the PN value of the first data frame and the initial PN value and the PN value range identified by the third identification information, and whether the PN value of the first data frame and the initial PN value are in a gradually increasing relationship.

[0080] In combination with some embodiments of the second aspect, in some embodiments, the third identification information is carried in the MAC frame header position of the first data frame.

[0115] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0116] As shown in FIG1 , a communication system 100 includes a transmitting end 101 and a receiving end 102 for performing data transmission.

[0117] In some embodiments, the transmitting end and the receiving end can be determined according to actual needs. For example, when the data transmission process occurs between a station device (STA) and an access point device (AP), the transmitting end can be a STA and the corresponding receiving end can be an AP; or, the transmitting end can be an AP and the corresponding receiving end can be a STA.

[0118] The STA includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in smart grids, a wireless terminal device used in transportation safety, a wireless terminal device used in smart cities, and a wireless terminal device used in smart homes.

[0119] Specifically, a STA can be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the STA can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[0120] In some embodiments, an AP can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, as well as support the next generation 802.11 protocol, but is not limited to these.

[0121] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0122] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0123] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0124] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an independent basic service set (IBSS). Another more common scenario is that in a BSS network, there is only one central station with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.

[0125] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0126] Step 201: The transmitting end determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies whether the transmitting end supports out-of-order transmission of data frames.

[0127] In some embodiments, the first radio frame can be transmitted between a STA and an AP, and the transmitter and receiver of the first radio frame can be determined based on actual needs. For example, the transmitter of the first radio frame can be a STA, and the corresponding receiver of the first radio frame can be an AP; alternatively, the transmitter of the first radio frame can also be an AP, and the corresponding receiver of the first radio frame can be a STA.

[0128] In UHR, the AP may also be a device that supports multi-link communication (e.g., STR or NSTR), that is, AP MLD, and the STA may also be attached to a non-AP MLD and support multi-link communication, and multi-link communication will be established between the two according to the existing 802.11be architecture.

[0129] In some embodiments, when the transmitter of the first radio frame is a STA and the receiver of the first radio frame is an AP, the first radio frame includes at least one of a probe request frame, an association request frame, and a reassociation request frame. That is, during the process of establishing an association between the transmitter and receiver of the first radio frame, the first radio frame can be used to identify whether the transmitter supports out-of-order transmission of data frames.

[0130] When the transmitter of the first radio frame is an AP and the receiver of the first radio frame is a STA, the first radio frame includes at least one of a beacon frame, a probe response frame, an association response frame, and a reassociation response frame. That is, during the process of publishing or obtaining network information between the transmitter and receiver of the first radio frame, the first radio frame can be used to identify whether the transmitter supports out-of-order transmission of data frames.

[0131] Optionally, in an embodiment of the present disclosure, after the transmitter and receiver of the first radio frame establish an initial association, whether the transmitter supports out-of-order transmission of data frames may be identified through the first radio frame. Alternatively, before the transmitter and receiver of the first radio frame establish an initial association, whether the transmitter supports out-of-order transmission of data frames may be identified through the first radio frame.

[0132] When transmitting data frames, both the sender and receiver of the data frames support ordered transmission. The sender of the data frames typically uses an SN (sequence number) value to identify each transmitted data frame, and the SN values ​​assigned to the data frames to be transmitted are gradually increased, i.e., the difference between the SN values ​​of two adjacent transmitted data frames is a preset incremental tolerance, and the data frames are transmitted sequentially according to the size of the SN values ​​of the data frames. For example, when the preset incremental tolerance is 1, the SN values ​​assigned to the transmitted data frames can be 1, 2, 3, 4, ..., in sequence, and each data frame is transmitted sequentially in this order; when the preset incremental tolerance is 2, the SN values ​​assigned to the transmitted data frames can be 1, 3, 5, 7, ..., in sequence, and each data frame is transmitted sequentially in this order.

[0133] Accordingly, the receiving end can determine whether the currently received data frame has been duplicated based on the transmission order of the gradually increasing SN values, that is, determine the validity of the currently received data frame. For example, the sending end assigns SN=1 to the previously transmitted data frame and SN=2 to the currently transmitted data frame. After the receiving end receives the data frame with SN=1, it receives the data frame with SN=2. By comparing the current SN value (i.e., 2) with the initial SN value (i.e., 1), it is determined that the current SN value and the initial SN value are gradually increasing. Therefore, it can be determined that the currently received data frame is valid and the data frame transmission mode is orderly transmission.

[0134] However, when transmitting service data with the same TID (Traffic Identifier) ​​through this data frame transmission method, the service data may be divided into different data frames, and different SNs may be assigned to different data frames before the service data is transmitted. In addition, in UHR, it is necessary to transmit low-latency service data. When the service data is low-latency service data, in order to ensure the low latency of transmitting low-latency services, it may be necessary to transmit low-latency service data frames assigned a larger SN value before transmitting non-low-latency service data frames assigned a smaller SN value. Obviously, the above-mentioned data frame transmission method cannot be implemented. In view of this, the communication method provided by the embodiment of the present disclosure can be used to redefine the data frame transmission method of the two transmission ends (transmitting end and receiving end) of the data frame, and define that the transmission end can support the out-of-order transmission of data frames, that is, the transmission end can transmit data frames in a transmission order that gradually increases the SN value.

[0135] For example, the SN of the data frame last transmitted by the sender is 3, and the SN of the data frame currently transmitted is 8. The SN values ​​do not increase gradually. After the receiving end first receives the data frame with SN = 3 and then receives the data frame with SN = 8, it can compare the current SN value (i.e. 8) with the initial SN value (i.e. 3) to determine that the current SN value and the initial SN value do not increase gradually, and determine that the currently received data frame is valid, and the data frame transmission method is out of order.

[0136] In some embodiments, the first identification information is carried in a Media Access Control (MAC) capabilities field of an Ultra-High Reliability (UHR) (capabilities) information element of the first radio frame.

[0137] In some embodiments, the first identification information is set to a first parameter value, indicating that the transmitting end supports out-of-order transmission of data frames.

[0138] The first identification information can be set to "0" or "1" to indicate whether the transmitting end supports out-of-order transmission of data frames. For example, the first parameter value can be set to "1", that is, when the first identification information is set to "1", it indicates that the transmitting end supports out-of-order transmission of data frames; when the first identification information is set to "0", it indicates that the transmitting end does not support out-of-order transmission of data frames.

[0139] Step 202: The transmitting end sends the first wireless frame to the receiving end.

[0140] Optionally, as described above, after the initial association between the transmitter and receiver of the first radio frame is established, the first radio frame can be used to identify whether the transmitter supports out-of-order transmission of data frames. Alternatively, the first radio frame can be used to identify whether the transmitter supports out-of-order transmission of data frames before the initial association between the transmitter and receiver of the first radio frame is established. Therefore, the time to send the first radio frame to the receiver can be determined based on the actual transmission process.

[0141] In an embodiment of the present disclosure, the transmitting end determines the first wireless frame, and identifies whether the transmitting end supports the out-of-order transmission of data frames through the first identification information in the first wireless frame, so that the receiving end can obtain information about whether the transmitting end can support the out-of-order transmission of data frames. Further, when it is determined that both the receiving end and the transmitting end support the out-of-order transmission of data frames, higher-priority service data (for example, low-latency service data with a larger serial number) can be transmitted first to reduce transmission delay.

[0142] Step 203: The receiving end determines a second radio frame; wherein the second radio frame includes second identification information, and the second identification information identifies whether the receiving end supports out-of-order transmission of data frames.

[0143] The receiving end of the first radio frame is the transmitting end of the second radio frame. As previously mentioned, the transmitting end of the first radio frame is the STA and the receiving end of the first radio frame is the AP. This also means that the transmitting end of the second radio frame is the AP and the receiving end of the second radio frame is the STA. The transmitting end of the first radio frame is the AP and the receiving end of the first radio frame is the STA. This also means that the transmitting end of the second radio frame is the STA and the receiving end of the second radio frame is the AP.

[0144] In the disclosed embodiment, when the transmitter of the second radio frame is an AP and the receiver of the second radio frame is a STA, the second radio frame includes at least one of a beacon frame, a probe response frame, an association response frame, and a reassociation response frame. That is, during the process of publishing or obtaining network information between the transmitter and receiver of the second radio frame, the second radio frame can be used to identify whether the receiver supports out-of-order transmission of data frames.

[0145] When the transmitter of the second radio frame is a STA and the receiver of the second radio frame is an AP, the second radio frame includes at least one of a probe request frame, an association request frame, and a reassociation request frame. That is, during the association establishment process between the transmitter and receiver of the second radio frame, the second radio frame can be used to identify whether the receiver supports out-of-order transmission of data frames.

[0146] In some embodiments, the second identification information is carried in a MAC capabilities field of a UHR capabilities information element of the first radio frame.

[0147] In some embodiments, the second identification information is set to a second parameter value, indicating that the receiving end supports out-of-order transmission of data frames.

[0148] The second parameter value can be the same as the first parameter value. See the description of the first parameter value above. The second identification information can also be set to "0" or "1" to indicate whether the receiving end supports out-of-order transmission of data frames. For example, the second parameter value can also be set to "1", that is, when the second identification information is set to "1", it can be indicated that the receiving end supports out-of-order transmission of data frames; when the second identification information is set to "0", it can be indicated that the receiving end does not support out-of-order transmission of data frames.

[0149] Step 204: The receiving end sends the second wireless frame to the transmitting end.

[0150] Optionally, as described above, after the initial association is established between the transmitter and receiver of the first radio frame (that is, the receiver and transmitter of the second radio frame), the second radio frame may be used to identify whether the receiver supports out-of-order transmission of data frames. Alternatively, before the initial association is established between the transmitter and receiver of the first radio frame (that is, the transmitter and receiver of the second radio frame), the second radio frame may be used to identify whether the receiver supports out-of-order transmission of data frames. Therefore, the transmission time of the second radio frame can be determined based on the actual transmission process.

[0151] In the embodiment of the present disclosure, the transmission end (sending end and receiving end) of the data frame sends information to the opposite end whether it supports the out-of-order transmission of data frames, so that the transmission end can obtain information whether itself and the opposite end can support the out-of-order transmission of data frames. Then, when it is determined that both itself and the opposite end support the out-of-order transmission of data frames, in the process of data transmission with the opposite end, it can give priority to transmitting business data with higher priority (for example, low-latency business data with a larger serial number) to reduce transmission delay.

[0152] To prevent replay attacks during data frame transmission, a PN (packet number) can be defined. During data frame transmission, the receiving end can compare the PN value of the currently received data frame with the PN value of the last received data frame (i.e., the initial PN value). If the difference between the current PN value and the initial PN value is greater than 1, it is determined that the currently received data frame has not been subjected to a replay attack. If the current PN value is less than or equal to the initial PN value, or the difference between the current PN value and the initial PN value is significantly different, it is determined that the currently received data frame has been subjected to a replay attack.

[0153] In step 205, when the first identification information indicates that the sending end supports out-of-order transmission of data frames, and the second identification information indicates that the receiving end supports out-of-order transmission of data frames, the sending end determines the first data frame; wherein, the first data frame includes third identification information, and the third identification information identifies the message number PN (packet number) value range of the first data frame.

[0154] The first identification information identifies that the sending end instructs the out-of-order transmission of data frames, and the second identification information identifies that the receiving end supports out-of-order transmission of data frames, that is, the first identification information is set to the first parameter value, and the second identification information is set to the second parameter value.

[0155] Optionally, the PN value range can be obtained by negotiation between the sending end and the receiving end to define the difference range of the PN values ​​of two adjacent transmitted data frames when the sending end and the receiving end transmit data frames, that is, the difference range between the initial PN value of the first data frame transmitted last time and the PN value of the first data frame currently transmitted. In the embodiment of the present disclosure, the PN value range of the first data frame can also be called the PN value range of the PN window value.

[0156] In the embodiment of the present disclosure, the PN value range of the first data frame is identified by the third identification information in the first data frame, so that the receiving end of the first data frame can determine whether the transmission of the currently received first data frame is a valid out-of-order transmission based on the PN value range and the PN value of the first data frame received last time.

[0157] In some embodiments, the third identification information is carried in the MAC frame header position of the first data frame.

[0158] In the embodiment of the present disclosure, by carrying the third identification information in the MAC frame header position of the first data frame, the receiving end of the first data frame can determine whether the transmission of the currently received first data frame is a valid out-of-order transmission based on the third identification information.

[0159] In some embodiments, the PN value corresponds to a preset transmission identifier TID.

[0160] The TID is used to identify the service type of the transmitted data frame. For example, service types may include, but are not limited to, low-latency services. Specifically, they may include video services (VI), voice services (VO), best-effort services (BE), and background services (BK).

[0161] Optionally, the PN value may be mapped to one or more TIDs. For example, it may be configured that when PN=1, the corresponding TID is a low-latency service.

[0162] In the embodiment of the present disclosure, by matching the PN value with the TID, the receiving end of the first data frame can obtain the service type to which the first data frame belongs according to the PN value of the first data frame.

[0163] Step 206: The transmitting end sends the first data frame to the receiving end.

[0164] Step 207: The receiving end determines whether the transmission of the first data frame is a valid out-of-order transmission based on the PN value range identified by the third identification information in the first data frame, the initial PN value of the first data frame, and the PN value of the first data frame.

[0165] The initial PN value of the first data frame is the PN value of the first data frame received last time by the receiving end.

[0166] In an embodiment of the present disclosure, a receiving end may cache a received first data frame and an initial PN value of the first data frame. After receiving a new first data frame, the receiving end may determine whether a difference between the PN value of the first data frame and the initial PN value of the first data frame is within a PN value range. After determining that the difference between the PN value of the first data frame and the initial PN value of the first data frame is within the PN value range, the receiving end may further determine whether the initial PN value of the first data frame and the PN value of the first data frame are in a gradually increasing relationship. If it is determined that the difference between the PN value of the first data frame and the initial PN value of the first data frame is within the PN value range and that the initial PN value of the first data frame and the PN value of the first data frame are in a gradually increasing relationship, the transmission of the first data frame may be determined to be valid out-of-order transmission. Otherwise, the transmission of the first data frame may be determined to be invalid out-of-order transmission.

[0167] In some embodiments, in step 207a, the receiving end determines that the transmission of the first data frame is valid out-of-order transmission when the difference between the PN value of the first data frame and the initial PN value is less than or equal to the PN value range identified by the third identification information, and the PN value of the first data frame and the initial PN value are not in a gradually increasing relationship;

[0168] Step 207b: When the difference between the PN value of the first data frame and the initial PN value is greater than the PN value range identified by the third identification information, the receiving end determines that the transmission of the first data frame is invalid and out-of-order transmission.

[0169] The PN value of the first data frame is not in a step-by-step increasing relationship with the initial PN value, that is, the difference between the PN value of the first data frame and the initial PN value is greater than a preset incremental tolerance. For example, if the preset incremental tolerance is 1, and the order of the PN values ​​is 1, 2, 3, 4, ..., then the difference between the PN value of the first data frame and the initial PN value is greater than 1, and the PN value of the first data frame and the initial PN value are not in a step-by-step increasing relationship. If the preset incremental tolerance is 2, and the order of the PN values ​​is 1, 3, 5, 7, ..., then the difference between the PN value of the first data frame and the initial PN value is greater than 2, and the PN value of the first data frame and the initial PN value are not in a step-by-step increasing relationship.

[0170] Assuming that the initial PN value of the first data frame is PN1, the PN value of the first data frame is PN2, the PN value range is ΔPN, and the preset incremental tolerance is 1, if PN2-PN1≤ΔPN, and PN2-PN1>1, it can be determined that the transmission of the first data frame is valid out-of-order transmission. For example, when PN1=3, PN2=8, and ΔPN=32, it can be determined that PN2-PN1≤ΔPN, and PN2-PN1>1, and thus the transmission of the first data frame is valid out-of-order transmission.

[0171] Of course, in the embodiment of the present disclosure, the receiving end can cache the received first data frame and the initial PN value of the first data frame, and determine the optional range of the PN value of the first data frame received next time based on the initial PN value and PN value range of the first data frame, that is, (initial PN value + preset incremental tolerance) < PN value of the first data frame received next time ≤ (initial PN value + PN value range); after receiving the new first data frame, determine whether the PN value of the first data frame is within the optional range of the PN value of the first data frame; after determining that the PN value of the first data frame is within the optional range of the PN value of the first data frame, it can be further determined whether the initial PN value of the first data frame and the PN value of the first data frame are in a step-by-step increasing relationship; after determining that the PN value of the first data frame is within the optional range of the PN value of the first data frame, and the initial PN value of the first data frame and the PN value of the first data frame are in a step-by-step increasing relationship, it can be determined that the transmission of the first data frame is valid out-of-order transmission. Otherwise, it can be determined that the transmission of the first data is invalid out-of-order transmission.

[0172] Assuming that the initial PN value of the first data frame is PN1, the PN value of the first data frame is PN2, the PN value range is ΔPN, and the preset incremental tolerance is 1, then it can be determined that the optional range of the PN value of the next received first data frame is (PN1+2)<PN2'<(PN1+ΔPN). If PN2 is within this optional range and PN2-PN1>1, it can be determined that the transmission of the first data frame is valid out-of-order transmission. For example, when it is determined that PN1=3 and ΔPN=32, it can be determined that 3<PN2'<35. If PN2=8, it can be determined that 3<8<35 and PN2-PN1>1, and thus the transmission of the first data frame is valid out-of-order transmission.

[0173] Optionally, if PN2-PN1>ΔPN, it may be determined that the transmission of the first data frame is invalid and out-of-order transmission, and it may also be determined that a replay attack exists on the first data frame.

[0174] In the embodiment of the present disclosure, by determining the size relationship between the difference between the PN value of the first data frame and the initial PN value and the PN value range identified by the third identification information, and whether the PN value of the first data frame and the initial PN value are in a gradually increasing relationship, it is convenient to determine whether the transmission of the first data frame is a valid disordered transmission.
