Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a data transmission method, a data transmission device, and a storage medium. Background Art

[0002] In wireless environments, Internet Protocol (IP) packets may be discarded during transmission. For example, some IP packets may be lost due to transmission failure, or IP packets may become invalid due to excessive transmission delay.

[0003] When a service requires large amounts of data to be transmitted, multiple IP packets are required to arrive at the receiving end within a specified timeframe. If even one IP packet fails to arrive within that timeframe, all of the IP packets are invalidated. Alternatively, if a packet carrying critical data is lost, the remaining IP packets that reach the receiving end must be discarded, resulting in a waste of transmission resources.

[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0040] The IP protocol is generally used for various data transmissions in the Internet, and can also be applied in mobile communications. The protocol unit that the IP protocol controls transmission is called an IP datagram (IP datagram, IP packet, or IP group). Because the IP protocol masks the differences between the various physical subnets in the lower layer, it can provide IP datagrams of a unified format to the upper layer. IP datagrams use datagram packet transmission and provide connectionless services. The format of the IP datagram can determine the functions of the IP packet protocol. For example, an IPv4 datagram consists of two parts: a header and data. The data is the data that the higher layer needs to transmit, and the header is control information added to ensure the correct transmission of the higher layer data. The first part of the header is fixed in length, totaling 20 bytes, and is required for all IP datagrams. Following the fixed part of the header is the optional field, which has a variable length. Figure 1 FIG. 1 is a schematic diagram of an IP datagram format according to an exemplary embodiment. Figure 1 As shown, the fixed part includes: version, header length, differentiated services, total length, identification, flag, fragment offset, lifetime, protocol, header checksum, source address and destination address.

[0041] Among them, (1) Version, which occupies 4 bits, refers to the version of the IP protocol. The IP protocol version used by both communicating parties must be the same. The widely used IP protocol version number is 4 (i.e. IPv4).

[0042] (2) The header length occupies 4 bits, and the maximum decimal value that can be represented is 15. It should be noted that the unit of the number represented by this field is 32-bit word length (1 32-bit word length is 4 bytes). Therefore, when the IP header length is 1111 (i.e., 15 in decimal), the header length reaches 60 bytes. When the header length of the IP packet is not an integer multiple of 4 bytes, it must be padded with the final padding field. Therefore, the data part always starts at an integer multiple of 4 bytes, which is more convenient when implementing the IP protocol. The disadvantage of limiting the header length to 60 bytes is that it may sometimes be insufficient. However, this is done in the hope that users will minimize overhead. The most commonly used header length is 20 bytes (i.e., the header length is 0101), and no options are used at this time.

[0043] (3) Differentiated Services (DTS) takes up 8 bits and is used to obtain better service. It can also be called the type of service. This field is used when using differentiated services.

[0044] (4) Total length: The total length is the sum of the header and data, expressed in bytes. The total length field is 16 bits, so the maximum length of a datagram is 2^16-1 = 65535 bytes.

[0045] Each data link layer below the IP layer has its own frame format, including a maximum length for the data field within the frame, called the Maximum Transfer Unit (MTU). When a datagram is encapsulated into a link layer frame, the total length of the datagram (i.e., the header plus the data portion) must not exceed the MTU value of the underlying data link layer.

[0046] (5) Identification occupies 16 bits. The IP software maintains a counter in memory. Every time a datagram is generated, the counter is incremented by 1 and this value is assigned to the identification field. However, this "identification" is not a sequence number, because IP is a connectionless service and there is no problem of receiving datagrams in order. When a datagram must be fragmented because its length exceeds the network's MTU, the value of this identification field is copied to the identification field of all datagrams. The same value of the identification field allows the fragmented datagram fragments to be correctly reassembled into the original datagram.

[0047] (6) Flag, occupies 3 bits, 2 of which are meaningful.

[0048] The lowest bit in the flags field is denoted as MF (More Fragments). MF = 1 indicates that there are more fragments of the datagram to come. MF = 0 indicates that this is the last fragment of a datagram. The middle bit in the flags field is denoted as DF (Don't Fragment), meaning "Don't fragment." Fragmentation is only allowed when DF = 0.

[0049] (7) Fragment offset, 13 bits. The fragment offset indicates the relative position of a fragment in the original packet after the fragmentation of a longer packet. It indicates where the fragment begins relative to the start of the user data field. The fragment offset is in units of 8 bytes. That is, except for the last fragment, the length of each fragment must be an integer multiple of 8 bytes (64 bits).

[0050] (8) Time to Live, occupies 8 bits. The commonly used abbreviation for the time to live field is TTL (Time To Live), which indicates the lifespan of the datagram in the network. This field is set by the source point that sends the datagram. Its purpose is to prevent undeliverable datagrams from circling around the Internet indefinitely, thereby wasting network resources. The original design used seconds as the unit of TTL. Every time a datagram passes through a router, the TTL is subtracted from the time the datagram spends in the router. If the time the datagram spends in the router is less than 1 second, the TTL value is reduced by 1. When the TTL value is 0, the datagram is discarded. Later, the function of the TTL field was changed to "hop limit" (but the name remains unchanged). The router reduces the TTL value by 1 before forwarding the datagram. If the TTL value is reduced to zero, the datagram is discarded and no longer forwarded. Therefore, the unit of TTL is no longer seconds, but hops. The meaning of TTL is to indicate how many routers a datagram can pass through at most in the network. Obviously, the maximum value of routers that a datagram passes through on the network is 255. If the initial value of TTL is set to 1, it means that this datagram can only be transmitted within this local area network.

[0051] (9) Protocol, occupies 8 bits. The protocol field indicates which protocol is used for the data carried by this datagram, so that the IP layer of the destination host knows which processing process the data part should be handed over to.

[0052] (10) Header checksum, occupies 16 bits. This field only checks the header of the datagram, but does not include the data portion. Since the router must recalculate the header checksum every time the datagram passes through it (including some fields such as the time to live, flags, and fragment offset, which may change), omitting the data portion can reduce the computational workload.

[0053] (11) Source address, 32 bits.

[0054] (12) Destination address, 32 bits.

[0055] Variable part

[0056] The variable portion of the IP header is an option field. This field supports troubleshooting, measurement, and security measures. The length of this field varies, ranging from 1 to 40 bytes, depending on the selected options. Some options require only a single byte, consisting of a single-byte option code. Other options, however, require multiple bytes. These options are concatenated without separators, and then padded with all-zeros to create an integer multiple of 4 bytes.

[0057] The addition of a variable header section increases the functionality of IP datagrams, but this also makes the length of the IP datagram header variable. This increases the overhead of each router processing the datagram. The new IP version, IPv6, makes the length of the IP datagram header fixed. These options are defined as follows:

[0058] (1) Security and processing restrictions (used in military fields).

[0059] (2) Record the path (have each router write down its IP address).

[0060] (3) Timestamp (let each router record the IP address and local time of each router the IP datagram passes through).

[0061] (4) Loose Source Route (specify a series of IP addresses that the datagram must pass through).

[0062] (5) Strict Source Route (similar to loose source routing, but requires that only the specified addresses can be passed through and no other addresses can be passed through).

[0063] In wireless communication environments, IP packets are subject to packet loss during transmission. For example, during data transmission from a network device to a terminal, not all IP packets reach the terminal. Some IP packets may be lost due to excessive latency or packet failure, preventing them from reaching the terminal.

[0064] Exemplary, for real-time video services, after a frame image on the screen generates data, it needs to be transmitted by multiple IP data packets, and these multiple IP data packets need to arrive at the receiving end within the time of image display. If the multiple IP data packets corresponding to the frame image do not arrive at the receiving end within the display time, it is determined that the multiple IP data packets are invalid because they cannot be displayed. In addition, the IP data packets required for a frame image include key IP data packets, that is, if the frame image is to be displayed, the key IP data packets must reach the receiving end. If the key IP data packets do not arrive at the receiving end, it is determined that the frame image cannot be displayed, and then the other IP data packets need to be discarded. The other IP data packets can be non-key IP data packets.

[0065] In some services, data transmission exhibits a certain regularity. For example, in video services, a fixed number of IP packets can be used to transmit a single frame of an image. This fixed number of IP packets can be N IP packets, where N is a positive integer. These N IP packets include a fixed number of critical data packets, while the remaining number of IP packets are non-critical IP packets. Based on this, the present disclosure proposes a data transmission method that determines a data transmission cycle based on the regularity of data transmission and periodically transmits the regular service data. This method can improve data transmission efficiency.

[0066] Figure 2 This is a diagram showing a communication system architecture of a network device and a terminal according to an exemplary embodiment. The communication method provided by the present disclosure can be applied to Figure 2 As shown in the communication system architecture diagram. Figure 2 As shown, the network side equipment can be based on Figure 2 The architecture shown sends signaling.

[0067] It is understandable that Figure 2 The communication system of the network equipment and the terminal shown is only for schematic illustration. The wireless communication system may also include other network equipment, such as core network equipment, wireless relay equipment and wireless backhaul equipment. Figure 2 The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0068] It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access / collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, which can also be called New Radio (NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as simply a network.

[0069] Furthermore, the network devices involved in the present disclosure may also be referred to as wireless access network devices. The wireless access network devices may be: base stations, evolved node Bs (base stations), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs) or transmission and reception points (TRPs), etc. They may also be gNBs in NR systems, or they may be components or part of devices constituting base stations. In the case of a vehicle-to-everything (V2X) communication system, the network devices may also be vehicle-mounted devices. It should be understood that in the embodiments of the present disclosure, there is no limitation on the specific technology and specific device form used by the network devices.

[0070] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: smart phones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0071] Figure 3 FIG. 1 is a flow chart showing a data transmission method according to an exemplary embodiment. Figure 3 As shown, the data transmission method is used in a data sending end and includes the following steps.

[0072] In step S11, the number of IP data packets is determined.

[0073] The number of IP data packets includes a first number and a second number.

[0074] In step S12, within a first data transmission period, first type data is transmitted based on the first quantity, and second type data is transmitted based on the second quantity.

[0075] In an embodiment of the present disclosure, the number of IP packets included in a transmission cycle is determined, where the number of IP packets is fixed. For example, N IP packets are determined to be included in a transmission cycle. Furthermore, M IP packets are determined to be used to transmit first-type data among the N IP packets, and the number of these M IP packets may also be fixed. Among the N IP packets, except for the M IP packets used to transmit the first-type data, the remaining IP packets are used to transmit second-type data, i.e., a second number of IP packets.

[0076] The data sending end fixes the data to be transmitted in the N IP data packets, and fixes the data to be transmitted in the N IP data packets in the manner of placing the first type of data in the first number of IP data packets and the second type of data in the second number of IP data packets. During the first transmission data cycle, the first type of data is transmitted based on the first number, and the second type of data is transmitted based on the second number.

[0077] Through the data transmission method provided by the embodiment of the present disclosure, different types of data are placed in corresponding IP data packets, and IP data packets are sent based on the transmission data cycle. By placing different types of data in IP data packets at different positions, IP data packets can be sent purposefully and the sending efficiency of IP data packets can be improved.

[0078] In some embodiments of the present disclosure, the importance of the first type of data is greater than that of the second type of data. That is, the data to be transmitted is divided into relatively important first type of data and relatively unimportant second type of data according to its importance.

[0079] In some embodiments of the present disclosure, data to be transmitted is placed in a fixed number of IP packets. Based on the data type, relatively important data is placed in a first number of IP packets, and relatively unimportant data is placed in a second number of IP packets. Within a data transmission cycle, the first number of IP packets precedes the second number of IP packets. The first number of IP packets are then sent before the second number of IP packets.

[0080] Figure 4 FIG. 1 is a flow chart showing a data transmission method according to an exemplary embodiment. Figure 4 As shown, the data transmission method is used in a data sending end and includes the following steps.

[0081] In step S21, in response to the first number of IP data packets being all successfully sent within the first time, the second type of data is sent.

[0082] The first time is the time when the first type of data is sent.

[0083] In an embodiment of the present disclosure, the data sending end sends data packets within the first transmission data cycle based on the first transmission data cycle, and first starts to send the first number of IP data packets. After all the IP data packets of the first data are successfully sent, that is, after all the first type of data are successfully sent, it is determined to send the IP data packets of the second data.

[0084] Figure 5 FIG. 1 is a flow chart showing a data transmission method according to an exemplary embodiment. Figure 5 As shown, the data transmission method is used in a data sending end and includes the following steps.

[0085] In step S31, in response to the first number of IP data packets not all being successfully sent within the first time, the first number of IP data packets are sent based on a next transmission data cycle of the first transmission data cycle.

[0086] In an embodiment of the present disclosure, if a data transmitter sends a fixed number of IP packets in a first transmission data cycle in the order of first sending a first number of IP packets and then sending a second number of IP packets, and if all first-type data is successfully sent within a required time within the first transmission data cycle, it is determined to stop sending the second-type data, that is, stop sending the second number of IP packets. Then, based on the next transmission data cycle, the first number of IP packets will be started.

[0087] For example, taking a video service as an example, a frame of video service is fixedly transmitted within a transmission data cycle, wherein one transmission data cycle includes N IP data packets. The relatively important data of the frame (i.e., the first type of data) is placed in a first number of IP data packets, where the first number can be M, and the relatively unimportant data (i.e., the second type of data) is placed in a second number of IP data packets, where the second number is NM. The first N IP data packets are sent first. If the first N IP data packets are successfully sent within the required first time, the NM IP data packets following the frame of image are continued to be sent. If the first N IP data packets are not successfully sent within the required first time, the sending of the NM IP data packets following the frame of image is abandoned, and the IP data packets of the next frame of image are started based on the transmission data cycle.

[0088] Through the data transmission method provided by the present disclosure, when the first type of data is not all sent successfully, the sending of the IP data packet after the current transmission data cycle is abandoned, which can reduce the waste of IP data packets and improve the transmission efficiency of IP data packets.

[0089] In some embodiments of the present disclosure, an IP data packet includes an identifier, and the identifier is used to indicate the type of data being transmitted. That is, the data sending end can identify a first number of IP data packets and a second number of IP data packets to identify the IP data packets of the transmission data type. As mentioned above, a transmission data cycle includes N IP data packets, and the first number is M. Then, the first number M IP data packets can be identified as N*X, N*X+1, N*X+2, ..., N*X+M-1 respectively. The second number, and NM IP data packets are identified as N*X+M, N*X+M+1, N*X+M+2, ..., N*X+N-1 respectively. Wherein X represents the order of data being transmitted. For example, if X is 1, then the transmission data cycle transmits the first frame image of the video service. If X is 2, then the transmission data cycle transmits the second frame image of the video service, and so on.

[0090] When all IP data packets identified as N*X, N*X+1, N*X+2, ..., N*X+M-1 are sent successfully, it is determined to send IP data packets identified as N*X+M, N*X+M+1, N*X+M+2, ..., N*X+N-1.

[0091] In some embodiments of the present disclosure, the number of IP data packets, the first number, and the second number are determined based on a protocol or a predefined rule.

[0092] In the embodiments of the present disclosure, the above embodiments can be applied to services with strong regularity, such as video services, and can certainly also be applied to other services.

[0093] In the embodiments of the present disclosure, the data sending end may be a terminal or a network device, which is not specifically limited here.

[0094] Based on the same concept, an embodiment of the present disclosure also provides a data transmission device.

[0095] It is understandable that the data transmission device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0096] Figure 6 FIG. 1 is a block diagram of a data transmission device according to an exemplary embodiment. Figure 6 The data transmission device 100 is applied to a data generation end and includes a determination module 101 and a transmission module 102.

The transmitting module 102 is configured to transmit a first type of data based on the first number and a second type of data based on the second number within a first data transmission period.

[0098] In the embodiment of the present disclosure, the importance of the first type of data is greater than the importance of the second type of data.

[0099] In the embodiment of the present disclosure, the first number of corresponding IP data packets are sent in an order before the second number of corresponding IP data packets are sent in an order.

[0100] In the embodiment of the present disclosure, the transmission module 102 is configured to transmit the second type of data in response to the first number of IP data packets being all successfully transmitted within a first time, wherein the first time is the time for transmitting the first type of data.

[0101] In the embodiment of the present disclosure, the transmission module 102 is further configured to send the first number of IP data packets based on the next transmission data cycle of the first transmission data cycle in response to the first number of IP data packets not all being sent successfully within the first time.

[0103] In the embodiment of the present disclosure, the number of IP data packets, the first number, and the second number are determined based on a protocol or a predefined rule.

[0104] Regarding the apparatus in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.
