[0074] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0075] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0076] The message data processing method provided by the embodiments of the present application can be applied to, for example, Figure 1 the application environment shown in the figure. Among them, the terminal 102 communicates with the base station 104 through the network. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The base station 104 is a radio transceiver station for transmitting and receiving information with the terminal 102 through a mobile communication switching center in a certain radio coverage area.

[0077] In one embodiment, as Figure 2 shown in the figure, a message data processing method is provided. Taking the method applied to the Figure 1 base station 104 in the figure as an example, the method includes the following steps:

[0078] Step S201: Receive the message data and determine the reception time of the message data; wherein, a time identifier is set in a preset layer field of the message data.

[0079] Specifically, the packet data may include packet data in 3G, 4G, 5G, and future mobile communication networks above 5G. Taking the 5G communication network as an example, refer to Figure 3 As shown, the service data of the terminal sequentially passes through the SDAP layer, PDCP layer, RLC layer, and MAC layer. Each layer performs an operation of adding a packet header to the received data. The obtained packet data includes the packet headers corresponding to each layer and the service data. The packet data is sent to the base station through the uplink physical channel. After receiving the packet data on the uplink physical channel, the base station performs parsing and processing of the peer layers of the MAC layer, RLC layer, PDCP layer, and SDAP layer to restore the service data.

[0080] Step S203: Parse the time identifier of the preset layer field to obtain the sending time of the packet data.

[0081] Specifically, the preset layer may include any layer in the above packet data, such as the MAC layer. The preset layer field may include the field corresponding to the preset layer in the packet data header. The time identifier may include a custom time identifier, such as XX year XX month XX day; it may also include the above time identifier represented by other characters; it may also use the system frame, subframe number, time slot representation, or system frame number, subframe number, time slot, symbol. Among them, the system frame number, subframe number, time slot, symbol have higher time accuracy than the system frame, subframe number, time slot. In the 5G network, the duration of a system frame is 10 ms, each frame consists of 10 subframes, the duration of each subframe is 1 ms, the number of time slots included in each subframe increases with the increase of the parameter set, the parameter set represents the subcarrier spacing, and each time slot has 14 or 12 symbols. By parsing the time identifier, the sending time of the packet data can be obtained.

[0082] Step S205: Determine the data processing method of the packet data according to the magnitude relationship between the difference between the receiving time and the sending time and a preset threshold.

[0083] Specifically, the preset threshold can represent the target delay Tt, such as 3 ms, 6 ms, etc., which can be set according to specific application scenarios. The reception time can be marked as T1, the transmission time can be marked as T0, and the difference between the reception time and the transmission time can be expressed as Δt, then Δt = T1 - T0. In an exemplary embodiment, when the difference Δt is equal to Tt, the packet data can be sent to the upper layer of the preset layer for parsing. For example, if the preset layer is the MAC layer, the packet data parsed at the MAC layer can be sent to the RLC layer. In another exemplary embodiment, when the difference Δt is greater than Tt, the packet data can be discarded. Or, when the difference Δt is greater than Tt, the packet data can be discarded and a prompt message, such as an error message, can be sent. In another exemplary embodiment, when the difference Δt is less than Tt, a preset duration can be waited. When the preset duration ends, the packet data can be sent to the upper layer of the preset layer for parsing.

[0084] In the above method for processing packet data, the terminal side sets a time identifier in the preset layer field of the packet data. When the base station side parses the preset layer of the packet data, it obtains the transmission time of the packet data according to the time identifier, calculates the difference between the transmission time and the reception time, and compares the difference with the preset threshold to determine the processing method for the corresponding packet data, such as not sending, sending, or delaying sending, etc. This ensures the certainty of the delay difference (jitter) in the transmission of packet data.

[0085] In a possible implementation manner, the preset layer field includes a MAC layer field. Parsing the time identifier in the packet data to obtain the transmission time of the packet data includes:

[0086] Parsing the time identifier at a preset position in the MAC layer field of the packet data;

[0087] Determining the transmission time of the packet data according to the time identifier.

[0088] Specifically, the MAC (Medium Access Control) layer can include the MAC layers in 3G, 4G, 5G, and future mobile communication networks above 5G. Taking the MAC layer of 5G as an example, the MAC layer of 5G is located in the data link layer of the network structure. The functions of the MAC layer can include: mapping between logical channels and transport channels; multiplexing MAC SDUs from one or more logical channels into a transport block and delivering it to the PHY layer; demultiplexing the transport block received from the physical layer into multiple MAC SDUs and delivering them to one or more logical channels.

[0089] In the embodiments of the present disclosure, the preset position may include the head, middle, and tail of the MAC layer field sub-header. In an exemplary embodiment, if a time identifier is added to the head of the MAC layer field sub-header (where the sub-header starts), parsing also needs to be performed from the head of the MAC layer field sub-header. In another exemplary embodiment, if a time identifier is added to the middle of the MAC layer field sub-header, parsing also needs to be performed from the head of the MAC layer field sub-header. In another exemplary embodiment, if a time identifier is added to the tail of the MAC layer field sub-header, parsing also needs to be performed from the tail of the MAC layer field sub-header. In the embodiments of the present disclosure, the time identifier may include the time identifier represented by any one of the above embodiments.

[0090] Reference Figure 4 As shown, in an exemplary embodiment, in the packet data of a 5G mobile network, when L = 8 bits, 3 bytes are extended at the tail of the MAC layer field sub-header, where the extended part SFN is the system frame number, with a range of 0 to 1023 (10 bits); SubFN is the sub-frame number, with a range of 0 to 9 (4 bits); SlotN is the Slot number, with a range of 0 to 15 (4 bits).

[0091] Reference Figure 5 As shown, in an exemplary embodiment, in the packet data of a 5G mobile network, when L = 16 bits, 3 bytes are extended at the tail of the MAC layer field sub-header, where the extended part SFN is the system frame number, with a range of 0 to 1023 (10 bits); SubFN is the sub-frame number, with a range of 0 to 9 (4 bits); SlotN is the Slot number, with a range of 0 to 15 (4 bits).

[0092] In the embodiments of the present disclosure, the terminal side sets a time identifier in the MAC layer field of the packet data. When the base station side parses the MAC layer of the packet data, it obtains the sending time of the packet data according to the time identifier, calculates the difference between the sending time and the receiving time, compares the difference with a preset threshold, and determines the processing method of the corresponding packet data, such as not sending, sending, or delaying sending, etc. This ensures the certainty of the time delay difference (jitter) of the packet data transmission. Using the MAC layer field to set the time identifier has strong implementability.

[0093] In a possible implementation manner, the preset position includes the position of a preset number of bytes at the tail of the MAC layer field sub-header. Parsing the time identifier at the preset position in the MAC field of the packet data includes:

[0094] Parsing the time identifier at the position of a preset number of bytes at the tail of the MAC field header of the packet data; where the time identifier includes a combination of multiple sub-fields, and the sub-fields include: system frame number, sub-frame number, time slot, symbol.

[0095] Specifically, the preset position includes the position of the tail preset number of bytes of the MAC layer field sub-header. On the one hand, if the base station side implements the message data processing method described in any one of the embodiments of the present disclosure, as described in the above embodiments, it can help improve the determinism of the message data. On the other hand, if the base station side does not implement the message data processing method described in any one of the embodiments of the present disclosure, it can still be parsed in the original manner without causing the MAC layer to be unable to parse.

[0096] In an exemplary embodiment, referring to Figure 6 As shown, taking the message data of a 5G communication network as an example, 3 bytes are extended at the tail of the MAC layer field sub-header. When L = 8bit, among them, for the extended part, SFN is the system frame number, with a range of 0 to 1023 (10 bits); SubFN is the sub-frame number, with a range of 0 to 9 (4 bits); SlotN is the Slot number, with a range of 0 to 15 (4 bits); SymbolN is the Symbol number, with a range of 0 to 13 (4 bits).

[0097] In another exemplary embodiment, referring to Figure 7 As shown, taking the message data of a 5G communication network as an example, 3 bytes are extended at the tail of the MAC layer field sub-header. When L = 16bit, among them, for the extended part, SFN is the system frame number, with a range of 0 to 1023 (10 bits); SubFN is the sub-frame number, with a range of 0 to 9 (4 bits); SlotN is the Slot number, with a range of 0 to 15 (4 bits); SymbolN is the Symbol number, with a range of 0 to 13 (4 bits).

[0098] The embodiments of the present disclosure use the system frame number, sub-frame number, time slot, and symbol to represent time, which further refines the time granularity, improves the accuracy of the time delay difference, and further improves the determinism of the time delay difference (jitter) of the message data transmission.

[0099] In a possible implementation manner, according to the magnitude relationship between the difference between the receiving time and the sending time and a preset threshold, determining the processing manner of the message data includes:

[0100] When the difference between the receiving time and the sending time is equal to the preset threshold, sending the parsed message data to the layer above the preset layer.

[0101] Specifically, when the base station side parses the preset layer of the message data, it obtains the sending time of the message data and the parsed message data. The difference between the receiving time and the sending time is calculated. If the difference is equal to the preset threshold, the parsed message data can be sent to the upper layer of the preset layer, so that the upper layer of the preset layer can further parse the parsed message data. For example, after the MAC layer parses, the sending time of the message data and the parsed message data are obtained. If the difference between the receiving time and the sending time is equal to the preset threshold, the parsed message data is sent to the RLC layer, so that the RLC layer parses the message data.

[0102] In the embodiment of the present disclosure, by comparing the difference between the receiving time and the sending time with the size of a preset threshold, when the two are equal, the parsed message data is sent to the upper layer of the preset layer, which is beneficial to promoting the consistency of the delay time of multiple message data and improving the certainty of the message data delay.

[0103] In one possible implementation, determining a processing method for the message data according to a relationship between a difference between the receiving time and the sending time and a preset threshold value includes:

[0104] When the difference between the receiving time and the sending time is less than the preset threshold, wait for a preset time period; wherein the preset time period is the difference between the preset threshold and the difference;

[0105] When the preset time period ends, the parsed message data is sent to the upper layer of the preset layer.

[0106] Specifically, when the base station side parses the preset layer of the message data, it obtains the sending time of the message data and the parsed message data. The difference between the receiving time and the sending time is calculated. If the difference is less than the preset threshold, the preset time length can be waited. Specifically, for example, the message data is cached, a timer task is set, and when the preset time length expires, the parsed message data is sent to the upper layer of the preset layer. The preset time length may include the difference between the preset threshold and the difference. In an exemplary embodiment, after the MAC layer parses, the sending time of the message data and the parsed message data are obtained. If the difference between the receiving time and the sending time is less than the preset threshold, the difference between the preset threshold and the difference is waited. After the waiting is over, the parsed message data is sent to the RLC layer so that the RLC layer parses the message data.

[0107] In an embodiment of the present disclosure, by comparing the difference between the reception time and the transmission time with a preset threshold, when the difference between the reception time and the transmission time is less than the preset threshold, wait for a preset duration. When the preset duration ends, send the parsed message data to the layer above the preset layer, which is beneficial to promoting the consistency of the delay times of multiple message data and improving the determinacy of the message data delay.

[0108] In a possible implementation manner, determining the processing method of the message data according to the magnitude relationship between the difference between the reception time and the transmission time and the preset threshold includes:

[0109] When the difference between the reception time and the transmission time is greater than the preset threshold, send a prompt message.

[0110] Specifically, when the base station side parses the preset layer of the message data, it obtains the transmission time of the message data and the parsed message data. Calculate the difference between the reception time and the transmission time. If the difference is greater than the preset threshold, the message data can be discarded, or a prompt message can be sent while discarding the message data. The prompt message is used to prompt that the delay of the message data times out and cannot meet the determinacy requirement. Subsequently, it can be further processed by retransmission or other means.

[0111] In an embodiment of the present disclosure, by comparing the difference between the reception time and the transmission time with a preset threshold, when the difference between the reception time and the transmission time is greater than the preset threshold, send a prompt message, which avoids subsequent parsing of message data with a large delay and improves the determinacy of the message data delay.

[0112] Based on the same inventive concept, Figure 8 For the second process schematic diagram of the processing method of message data in another embodiment, refer to Figure 8 as shown, applied to a terminal, the method includes:

[0113] Step S801, obtain service data.

[0114] Step S803, when encapsulating the service data at the preset layer, add a time identifier of the transmission time to obtain message data.

[0115] Step S805, send the message data to the base station to instruct the base station to parse the time identifier in the message data, obtain the transmission time of the message data; determine the data processing method of the message data according to the magnitude relationship between the difference between the reception time and the transmission time and the preset threshold.

[0116] Specifically, the service data may include various types of service data, which may include multiple types according to different application scenarios, such as streaming media data, report data, session data, etc. The preset layer may include any layer in the Internet reference model during data transmission, such as the MAC layer. Encapsulate the service data in the preset layer, referring to Figure 3 As shown, the service data of the terminal sequentially passes through the SDAP layer, PDCP layer, RLC layer, and MAC layer. Each layer performs an operation of adding an encapsulation header to the received data, and the obtained packet data includes the corresponding packet headers of each layer and the service data. In an exemplary embodiment, a time identifier may be added to the packet header of the preset layer.

[0117] Among them, the time identifier may include a custom time identifier, such as XX year XX month XX day; it may also include the above time identifier represented by other characters; it may also use system frame, subframe number, time slot representation, or system frame number, subframe number, time slot, symbol. Among them, the system frame number, subframe number, time slot, symbol have higher time accuracy compared to the system frame, subframe number, time slot. In the 5G network, the duration of a system frame is 10 ms, each frame consists of 10 subframes, the duration of each subframe is 1 ms, and the number of time slots included in each subframe increases with the increase of the parameter set. The parameter set represents the subcarrier spacing, and each time slot has 14 or 12 symbols. At the base station side, the transmission time of the packet data can be obtained by parsing the time identifier.

[0118] In the embodiments of the present disclosure, the preset threshold may represent the target delay Tt, such as 3 ms, 6 ms, etc., and can be set according to specific application scenarios. The reception time can be denoted as T1, the transmission time can be denoted as T0, and the difference between the reception time and the transmission time can be denoted as Δt, then Δt = T1 - T0. In an exemplary embodiment, when the difference Δt is equal to Tt, the packet data may be sent to the upper layer of the preset layer for parsing. For example, if the preset layer is the MAC layer, the packet data parsed in the MAC layer may be sent to the RLC layer. In another exemplary embodiment, when the difference Δt is greater than Tt, the packet data may be discarded. Or, when the difference Δt is greater than Tt, the packet data may be discarded and a prompt message, such as an error message, may be sent. In another exemplary embodiment, when the difference Δt is less than Tt, a preset duration may be waited. When the preset duration ends, the packet data may be sent to the upper layer of the preset layer for parsing.

[0119] In the above method for processing the message data, the terminal side sets a time identifier in a preset layer field of the message data. When the base station side parses the preset layer of the message data, it obtains the sending time of the message data according to the time identifier, calculates the difference between the sending time and the receiving time, compares the difference with a preset threshold, and determines the processing method for the corresponding message data, such as not sending, sending, or delaying sending, etc., ensuring the certainty of the time delay difference (jitter) of the message data transmission.

[0120] In a possible implementation manner, when the base station executes parsing the time identifier in the message data to obtain the sending time of the message data, it includes:

[0121] The base station is used to parse the time identifier at a preset position in the MAC layer field of the message data;

[0122] According to the time identifier, determine the sending time of the message data.

[0123] Specifically, the MAC (Medium Access Control) layer may include the MAC layers in 3G, 4G, 5G, and future mobile communication networks above 5G. Taking the MAC layer of 5G as an example, the MAC layer of 5G is located in the data link layer of the network structure, and the functions of the MAC layer may include: mapping between logical channels and transport channels; multiplexing MAC SDUs from one or more logical channels into a transport block and delivering it to the PHY layer; demultiplexing the transport block received from the physical layer into multiple MAC SDUs and delivering it to one or more logical channels.

[0124] In the embodiments of the present disclosure, the preset position may include the head, middle, and tail of the MAC layer field sub-header. In an exemplary embodiment, if a time identifier is added at the head of the MAC layer field sub-header (the beginning of the sub-header), parsing also needs to be performed from the head of the MAC layer field sub-header. In another exemplary embodiment, if a time identifier is added in the middle of the MAC layer field sub-header, parsing also needs to be performed from the head of the MAC layer field sub-header. In another exemplary embodiment, if a time identifier is added at the tail of the MAC layer field sub-header, parsing also needs to be performed from the tail of the MAC layer field sub-header. In the embodiments of the present disclosure, the time identifier may include the time identifier represented by any one of the above embodiments.

[0125] In a possible implementation manner, the preset position includes a position at a preset number of bytes at the tail of the MAC layer field sub-header. The base station is used to parse the time identifier at the preset position in the MAC field of the message data, including:

[0126] The base station is used to parse the time stamp at the position of the preset number of bytes at the tail of the MAC field header in the packet data; wherein, the time stamp includes a combination of multiple sub-fields, and the sub-fields include: system frame number, sub-frame number, time slot, symbol.

[0127] Specifically, the preset position includes the position of the preset number of bytes at the tail of the MAC layer field sub-header. On the one hand, if the base station side implements the packet data processing method described in any one of the embodiments of the present disclosure, as described in the above embodiments, it can help improve the determinacy of the packet data. On the other hand, if the base station side does not implement the packet data processing method described in any one of the embodiments of the present disclosure, it can still be parsed in the original way without causing the MAC layer to be unable to parse.

[0128] In the embodiments of the present disclosure, the system frame number, sub-frame number, time slot, and symbol are used to represent time, which further refines the time granularity, improves the accuracy of the time delay difference, and further improves the determinacy of the time delay difference (jitter) of packet data transmission.

[0129] In a possible implementation manner, specifically, when the base station side parses a preset layer of packet data, it obtains the transmission time of the packet data and the parsed packet data. Calculate the difference between the reception time and the transmission time. If the difference is equal to the preset threshold, if the difference is equal to the preset threshold, the parsed packet data can be sent to the upper layer of the preset layer, so that the upper layer of the preset layer further parses the parsed packet data. For example, after parsing at the MAC layer, the transmission time of the packet data and the parsed packet data are obtained. If the difference between the reception time and the transmission time is equal to the preset threshold, the parsed packet data is sent to the RLC layer so that the RLC layer parses the packet data.

[0130] In the embodiments of the present disclosure, by comparing the difference between the reception time and the transmission time with the preset threshold, when the two are equal, sending the parsed packet data to the upper layer of the preset layer is beneficial to promoting the consistency of the delay times of multiple packet data and improving the determinacy of the packet data time delay.

[0131] Figure 9 For the third process schematic diagram of the packet data processing method in another embodiment, refer to Figure 9As shown, on the terminal side, service data sequentially passes through the SDAP layer, RLC layer, and MAC layer, with headers added layer by layer. Among them, a time identifier T0 is inserted at the MAC layer. The packet data with the time identifier is transmitted through the air interface to reach the base station side. The base station side parses the packet data. When parsing the MAC layer, it interprets the time identifier T0 to determine the sending time of the packet data, and based on the sending time and the receiving time T1 of the packet data, determines the time difference between T1 and T0. Compare this time difference with the target delay Tt. If they are equal, the packet data parsed at the MAC layer can be uploaded to the RLC layer for parsing; if the time difference is less than the target delay, buffer the packet sequence, and after the preset duration Tt - (T1 - T0) ends, upload the packet data parsed at the MAC layer to the RLC layer for parsing; if the time difference is greater than the target delay, discard it or perform other operations such as error reporting. The parsed packet data is parsed layer by layer to obtain the service data.
