Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a parsing method, apparatus, device, chip, and medium. Background Technology

[0002] In communication, hardening the downlink data of the protocol stack can reduce the software's demand for Million Instructions Per Second (MIPS) for protocol header parsing and protocol processing, freeing up considerable MIPS resources and improving the throughput of the downlink data link. Summary of the Invention

[0003] This disclosure aims to at least partially address one of the technical problems in the related art.

[0004] Therefore, this disclosure proposes a parsing method, apparatus, communication device, chip, computer-readable storage medium, and computer program product that can save the MIPS resources required for parsing processing and improve parsing efficiency and effectiveness.

[0005] The first aspect of this disclosure provides a parsing method, comprising: determining a first offset position corresponding to a sublayer of the data link layer, wherein the first offset position is used to represent the offset position of a first protocol header in a first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to a second protocol header, and the second protocol header is the protocol header of the data link layer; and determining information of the first protocol header based on the first offset position and the first bitstream.

[0006] A second aspect of this disclosure provides a parsing apparatus, comprising: a first determining module, configured to determine a first offset position corresponding to a sublayer of the data link layer, wherein the first offset position represents the offset position of a first protocol header in a first bitstream, the first protocol header being the protocol header of a sublayer, the first bitstream being the bitstream corresponding to a second protocol header, and the second protocol header being the protocol header of the data link layer; and a second determining module, configured to determine information of the first protocol header based on the first offset position and the first bitstream.

[0007] A third aspect of this disclosure provides a communication device, including: a processor and a memory communicatively connected to the processor; the memory stores computer-executable instructions; the processor executes the computer-executable instructions stored in the memory to implement the parsing method proposed in the above-described aspects of this disclosure.

[0008] A fourth aspect of this disclosure provides a chip including a processing circuit and an interface circuit; wherein the interface circuit is used to read instructions and send the instructions to the processing circuit so that the processing circuit executes the parsing method as proposed in the first aspect of this disclosure.

[0009] The fifth aspect of this disclosure provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, are used to implement the parsing method described above.

[0010] The parsing method, apparatus, communication equipment, chip, computer-readable storage medium, and computer program product provided in this disclosure determine a first offset position corresponding to a sublayer of the data link layer. This first offset position represents the offset position of a first protocol header within a first bitstream. The first protocol header is the protocol header of a sublayer, the first bitstream is the bitstream corresponding to a second protocol header, and the second protocol header is the protocol header of the data link layer. Based on the first offset position and the first bitstream, information about the first protocol header is determined. Since the first offset positions of each sublayer of the data link layer are obtained in advance, and the offset position of the first protocol header of the sublayer within the L2 protocol header bitstream is determined, it effectively supports subsequent pre-fetching of the sublayer protocol header bitstream. This enables parallel processing of parsing and copying the protocol header bitstream, thereby significantly saving MIPS resources required for parsing and improving parsing efficiency and effectiveness.

[0034] In communication, hardening the downlink data of the protocol stack can reduce the software's demand for Million Instructions Per Second (MIPS) for protocol header parsing and protocol processing, freeing up considerable MIPS resources and improving the throughput of the downlink data link.

[0035] like Figure 1B As shown, Figure 1B This is a schematic diagram of the TB distribution in the NR system according to an embodiment of this disclosure. In the NR system, a Transport Block (TB) can contain several Medium Access Control Sub Protocol Data Units (MAC subPDUs). Each MAC subPDU includes: an L2 header, a MAC header, a Radio Link Control (RLC) header, a Packet Data Convergence Protocol (PDCP) header, a Service Data Adaptation Protocol (SDAP) header, a Service Data Unit (SDAPSDU) of the Service Data Adaptation Protocol, and a PDCP SDU. Each MAC subPDU occupies an independent contiguous memory space on the TB, and all headers are distributed in the initial contiguous memory of the MAC subPDU. The bitstream of all headers for each MAC subPDU can be obtained at once, allowing for independent parsing of the headers of a single MAC subPDU.

[0036] like Figure 1C As shown, Figure 1CThis is a schematic diagram of the TB distribution in an LTE system according to an embodiment of this disclosure. In an LTE system, a MAC subPDU includes: a MAC protocol header, an RLC protocol header group, and a PDCP Packet Data Unit (PDCP PDU) group. The RLC protocol header group includes: an RLC protocol header (e.g., RLC header com, RLC header L; for detailed explanation, please refer to subsequent embodiments). The PDCP PDU group includes: a PDCP protocol header and a PDCP SDU. MAC subPDUs are concatenated and discretely distributed on the TB, requiring concatenation based on discrete memory addresses to obtain the overall protocol header bitstream. Therefore, it is necessary to design a protocol header parsing method compatible with various communication systems, saving the MIPS resources required for parsing processing, and improving parsing efficiency and effectiveness.

[0037] Optionally, the protocol header can also be called header, header information, header, etc., without restriction.

[0038] The following description, with reference to the accompanying drawings, describes the analytical methods, apparatus, communication devices, communication systems, chips, and storage media according to embodiments of the present disclosure.

[0039] Figure 2 This is a flowchart illustrating an analysis method provided in an embodiment of the present disclosure.

[0040] The parsing method provided in this embodiment can be applied to a terminal, network device, or chip. Optionally, the executing entity of the parsing method in this embodiment can be, for example, a terminal, network device, or chip. The chip can be deployed in a terminal or network device, or it can be deployed in any other possible device, without limitation.

[0041] like Figure 2 As shown, this parsing method includes:

[0042] Step S201: Determine the first offset position corresponding to the sublayer of the data link layer, wherein the first offset position is used to represent the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer.

[0043] The data link layer (Layer 2, L2) is responsible for ensuring reliable data transmission between adjacent nodes above the physical layer. It constructs logical communication links through functions such as frame encapsulation, MAC addressing, and error control. The data link layer contains sublayers, such as the MAC layer, Radio Link Control (RLC) layer, and Packet Data Convergence Protocol (PDCP) layer.

[0044] The first protocol header mentioned above is the sublayer protocol header. The first protocol header can also be referred to as the sublayer protocol header. The first protocol header includes, for example, the MAC header, RLC header, and PDCP header. The RLC header can further contain two finer-grained protocol headers: RLC header com and RLC header L. RLC header com can represent the offset field in the RLC layer header used for processing segmentation and concatenation. RLC header L is a key field in the RLC header, used to indicate the data length of the payload (RLC Service Data Unit (RLCSDU)) in the current Radio Link Control Protocol Data Unit (RLC PDU).

[0045] The second protocol header mentioned above is the data link layer protocol header. For example, the L2 protocol header.

[0046] The first bitstream is the bitstream corresponding to the second protocol header. The first bitstream refers to the structured data stream formed by combining the second protocol header, which is used to control data transmission, with the payload. The first bitstream can also be called the "L2 protocol header bitstream".

[0047] Among them, the "first offset position corresponding to the sublayer of the data link layer" mentioned above, the first offset position is used to describe the offset of the first protocol header of the corresponding sublayer in the first bit stream.

[0048] For example, in this embodiment of the disclosure, the offset of each sublayer protocol header in the L2 protocol header stream can be found (e.g., described by a first offset position corresponding to the sublayer): this is achieved through a mechanism of fixed offsets of each sublayer in the L2 protocol header stream (i.e., the maximum value of each sublayer protocol header). Specifically, the offset of the MAC header in the L2 protocol header stream is 0; the maximum length of the MAC header is 3 bytes; the offset of the RLC header com in the L2 protocol header stream is 3 bytes; the maximum length of the RLC header com is 5 bytes; the offset of the RLC header L in the L2 protocol header stream is 8 bytes; the maximum length of the RLC header L is 2 bytes; and the offset of the PDCP header in the L2 protocol header stream is 10 bytes.

[0049] In other words, in the embodiments of this disclosure, the first offset position corresponding to each sublayer of the data link layer can be predetermined, wherein the first offset position is used to represent the offset position of the first protocol header of the corresponding sublayer in the first bitstream, and then the information of the first protocol header of the sublayer is parsed based on the first offset position of the sublayer.

[0050] Step S202: Determine the information of the first protocol header based on the first offset position and the first bitstream.

[0051] The first protocol header corresponds to a sublayer. Each sublayer corresponds to at least one first protocol header. The information in the first protocol header is the specific content contained in the protocol header, such as key parameters such as protocol version, control fields, and address identifiers. There are no restrictions on this.

[0052] In this embodiment of the disclosure, the information of the first protocol header can be parsed based on the first offset position corresponding to each sublayer of the data link layer and the first bitstream. For example, a second bitstream can be prefetched. The second bitstream is the bitstream corresponding to the first protocol header. The second bitstream refers to the structured data stream formed by combining the first protocol header used to control data transmission with the payload. The second bitstream can also be called a "sublayer protocol header bitstream." The second bitstream is, for example, a MAC header bitstream, an RLC header bitstream, a PDCP header bitstream, etc. After prefetching the second bitstream, the information of the first protocol header can be parsed based on the first bitstream, the second bitstream, and the first offset position. For example, parsing can be performed based on a hardening processing method, or through a model, or through any chip that supports hardening acceleration processing (e.g., a hardening accelerator), etc., without limitation.

[0053] In this embodiment, by determining the first offset position corresponding to the sublayer of the data link layer, where the first offset position represents the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer, the information of the first protocol header is determined based on the first offset position and the first bitstream. Since the first offset positions of each sublayer of the data link layer are obtained in advance, and the offset position of the first protocol header of the sublayer in the L2 protocol header bitstream is determined, it can effectively support subsequent pre-fetching of the sublayer protocol header bitstream, thereby enabling parallel processing of parsing the protocol header and copying the protocol header bitstream. This significantly saves the MIPS resources required for parsing processing and improves parsing efficiency and effectiveness.

[0054] Figure 3 This is a flowchart illustrating another parsing method provided in an embodiment of this disclosure.

[0055] The parsing method provided in this embodiment can be applied to a terminal, network device, or chip. Optionally, the executing entity of the parsing method in this embodiment can be, for example, a terminal, network device, or chip. The chip can be deployed in a terminal or network device, or it can be deployed in any other possible device, without limitation.

[0056] like Figure 3 As shown, this parsing method includes:

[0057] Step S301: Determine the first offset position corresponding to the sublayer of the data link layer, wherein the first offset position is used to represent the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer.

[0058] The data link layer (Layer 2, L2) is responsible for ensuring reliable data transmission between adjacent nodes above the physical layer. It constructs logical communication links through functions such as frame encapsulation, MAC addressing, and error control. The data link layer contains sublayers, such as the MAC layer, Radio Link Control (RLC) layer, and Packet Data Convergence Protocol (PDCP) layer.

[0059] Optionally, the protocol header can also be called header, header information, header, etc., without restriction.

[0060] The first protocol header mentioned above is the sublayer protocol header. The first protocol header can also be referred to as the sublayer protocol header. The first protocol header includes, for example, the MAC header, RLC header, and PDCP header. The RLC header can further contain two finer-grained protocol headers: RLC header com and RLC header L. RLC header com can represent the offset field in the RLC layer header used for processing segmentation and concatenation. RLC header L is a key field in the RLC header, used to indicate the data length of the payload (RLC Service Data Unit (RLCSDU)) in the current Radio Link Control Protocol Data Unit (RLC PDU).

[0061] The second protocol header mentioned above is the data link layer protocol header. For example, the L2 protocol header.

[0062] The first bitstream is the bitstream corresponding to the second protocol header. The first bitstream refers to the structured data stream formed by combining the second protocol header, which is used to control data transmission, with the payload. The first bitstream can also be called the "L2 protocol header bitstream".

[0063] Among them, the "first offset position corresponding to the sublayer of the data link layer" mentioned above, the first offset position is used to describe the offset of the first protocol header of the corresponding sublayer in the first bit stream.

[0064] For example, in this embodiment of the disclosure, the offset of each sublayer protocol header in the L2 protocol header stream can be found (e.g., described by a first offset position corresponding to the sublayer): this is achieved through a mechanism of fixed offsets of each sublayer in the L2 protocol header stream (i.e., the maximum value of each sublayer protocol header). Specifically, the offset of the MAC header in the L2 protocol header stream is 0; the maximum length of the MAC header is 3 bytes; the offset of the RLC header com in the L2 protocol header stream is 3 bytes; the maximum length of the RLC header com is 5 bytes; the offset of the RLC header L in the L2 protocol header stream is 8 bytes; the maximum length of the RLC header L is 2 bytes; and the offset of the PDCP header in the L2 protocol header stream is 10 bytes.

[0065] In other words, in the embodiments of this disclosure, the first offset position corresponding to each sublayer of the data link layer can be predetermined, wherein the first offset position is used to represent the offset position of the first protocol header of the corresponding sublayer in the first bitstream, and then the information of the first protocol header of the sublayer is parsed based on the first offset position of the sublayer.

[0066] Step S302: Determine the second bitstream based on the transport block TB of the data link layer, wherein the second bitstream is the bitstream corresponding to the first protocol header.

[0067] Optionally, the second bitstream is the bitstream corresponding to the first protocol header. The second bitstream refers to the structured data stream formed by combining the first protocol header (used to control data transmission) with the payload. The second bitstream can also be called a "sublayer protocol header bitstream." Examples of second bitstreams include MAC header bitstreams, RLC header bitstreams, PDCP header bitstreams, etc. The RLC header bitstream can further include RLC header COM bitstreams and RLC header L bitstreams; there are no restrictions on this.

[0068] Optionally, the number of Data Link Layer (TB) mentioned above can be one or more. Each TB can be parsed to parse the protocol header information of each sublayer within that TB. A TB can contain several MAC PDUs, and a MAC PDU can contain several MAC subPDUs. The second stream can specifically be, for example, a structured data stream containing the first protocol header of the corresponding sublayer within the entire TB.

[0069] Optionally, in determining the second bitstream based on the transport block (TB) of the data link layer, a second offset position corresponding to the sublayer can be determined. This second offset position represents the offset position of the second bitstream within the TB of the data link layer, and the second bitstream is retrieved from the TB of the data link layer based on this second offset position. This enables rapid determination of the second bitstream corresponding to the first protocol header of the sublayer and supports improved accuracy and efficiency of subsequent prefetching of the second bitstream.

[0070] Optionally, a sublayer has a first protocol header, and the first protocol header has a corresponding second bitstream. Therefore, a sublayer has a corresponding second bitstream, and this sublayer also has a corresponding upper sublayer (e.g., the upper sublayer of the RLC layer is the MAC layer, and the upper sublayer of the PDCP layer is the RLC layer). Optionally, after obtaining the second bitstream corresponding to the upper sublayer, a second offset position corresponding to the sublayer can be determined based on the condition of the upper sublayer's second bitstream (e.g., the length of the second bitstream). The "second offset position corresponding to the sublayer" represents the offset position of the sublayer's second bitstream in the data link layer's TB. The second offset position can be used to obtain the second bitstream of the corresponding sublayer from the data link layer's TB.

[0071] Optionally, in determining the second offset position corresponding to the sublayer, if the sublayer is a Media Access Control (MAC) layer, the starting position in the Data Link Layer's TB (Transmission Block) can be determined as the second offset position corresponding to the MAC layer; if the sublayer is a Radio Link Control (RLC) layer, the second offset position corresponding to the RLC layer can be determined based on the length of the second bitstream of the MAC layer and the total length of at least one second bitstream of the RLC layer; if the sublayer is a Packet Data Convergence Protocol (PDCP) layer, the second offset position corresponding to the PDCP layer can be determined based on the length of the Service Data Unit (SDU) of the RLC layer. This significantly improves the accuracy of bitstream parsing and ensures that the obtained second bitstream has better integrity.

[0072] Step S303: Determine the information of the first protocol header based on the first offset position, the first bitstream, and the second bitstream.

[0073] Optionally, in determining the information of the first protocol header based on the first offset position, the first bitstream, and the second bitstream, the second bitstream can be inserted at the first offset position of the first bitstream to obtain a third bitstream, and the information of the first protocol header can be determined based on the third bitstream. That is, the second bitstream can be prefetched and copied to the first bitstream at the first offset position. The processed first bitstream can be referred to as the third bitstream, and then the information of the first protocol header can be obtained by parsing the third bitstream.

[0074] Optionally, in the process of determining the information of the first protocol header based on the third bitstream, the entity configuration parameters of the sublayer can be determined, and the third bitstream can be parsed according to the entity configuration parameters to obtain the information of the first protocol header. This can greatly improve the accuracy of parsing the information of the first protocol header.

[0075] For example, "sub-layer entity configuration parameters" can be: entity configuration parameters for the MAC layer, represented as mac_entity_cfg; entity configuration parameters for the RLC layer, represented as rlc_entity_cfg; entity configuration parameters for the PDCP layer, represented as pdcp_entity_cfg, etc. There are no restrictions on this.

[0076] In this embodiment, by determining the first offset position corresponding to the sublayer of the data link layer, where the first offset position represents the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer, the information of the first protocol header is determined based on the first offset position and the first bitstream. Since the first offset positions of each sublayer of the data link layer are obtained in advance, and the offset position of the first protocol header of the sublayer in the L2 protocol header bitstream is determined, it can effectively support the subsequent prefetching of the sublayer protocol header bitstream, enabling parallel processing of parsing the protocol header and copying the protocol header bitstream, thereby significantly saving MIPS resources for parsing and improving parsing efficiency and effectiveness. By determining the second bitstream based on the transport block (TB) of the data link layer, where the second bitstream is the bitstream corresponding to the first protocol header, and based on the first offset position, the first bitstream, and the second bitstream, the information of the first protocol header is determined. Therefore, it is possible to quickly determine the second bitstream corresponding to the first protocol header of the sublayer and support improved accuracy and efficiency of subsequent prefetching of the second bitstream.

[0077] like Figure 4 As shown, Figure 4 This is a schematic diagram of the parsing process in an embodiment of this disclosure. The sub-layers include the MAC layer, RLC layer, and PDCP layer, and the first protocol header includes: MAC header, RLC header (specifically including RLCheader L and RLC header com), and PDCP header.

[0078] The first bitstream is, for example, the L2 protocol header bitstream. The second bitstream includes, for example, the MAC header bitstream, the RLC header bitstream (e.g., the RLC header L bitstream, the RLC header COM bitstream), and the PDCP header bitstream.

[0079] Includes the following steps:

[0080] Step 1: MAC header length parsing: Starting from the position where offset=0 of TB (an optional example of the second offset position corresponding to the MAC layer mentioned above), start parse the MAC header in a loop until all MAC headers are parsed, obtain total_mac_header_len (an optional example of the length of the second bitstream of the MAC layer mentioned above), update mac_header_tb_offset, and copy the current MAC header bitstream (an optional example of the second bitstream corresponding to the MAC layer mentioned above) to the position where offset 0 of the L2 protocol header bitstream is (the first optional example of the first offset position corresponding to the MAC layer mentioned above).

[0081] Step 2: MAC Header Parsing: After parsing the MAC header, you will obtain the following parameters: lcid, mac_header_len, mac_sdu_len, rlc_entity_cfg, and pdcp_entity_cfg. Here, lcid represents the Logical Channel Identifier; mac_header_len represents the length of the MAC header; mac_sdu_len represents the length of the Service Data Unit (SDU) in the MAC layer; rlc_entity_cfg represents the entity configuration parameters in the RLC layer; and pdcp_entity_cfg represents the entity configuration parameters in the PDCP layer.

[0082] Based on total_mac_header_len, update rlc_header_com_tb_offset (an optional example of the second offset position corresponding to the RLC layer, where the second bitstream is, for example, the RLC header com bitstream), and copy the current RLC header bitstream to the L2 protocol header bitstream offset position 3, occupying a length of 5+2=7. Therefore, even without knowing rlc_header_com_len (an optional example of the length of the RLC header com bitstream), the effect of prefetching the RLC header L bitstream is achieved.

[0083] Step 3: RLC header length parsing: Starting from the rlc_header_com_tb_offset of the TB, the RLC header is parsed in a loop until all RLC headers are parsed, resulting in total_rlc_header_group_len (an optional example of the total length of at least one second bitstream of the RLC layer). Then, rlc_header_l_tb_offset (another optional example of the second offset position corresponding to the RLC layer, where the second bitstream is, for example, the RLC header L bitstream) and pdcp_header_tb_offset (another optional example of the second offset position corresponding to the PDCP layer, where the second bitstream is, for example, the PDCP header bitstream) are updated. Next, the current RLC header L bitstream is prefetched and copied to the L2 protocol header bitstream at offset=8 (an optional example of the first offset position corresponding to the RLC layer), and the PDCP header bitstream is copied to the L2 protocol header bitstream at offset=10 (the first optional example of the first offset position corresponding to the PDCP layer), thus completing the rlc_header_com header parsing.

[0084] Step 4: RLC header parsing: Combined with rlc_entity_cfg, the current RLC header is parsed to obtain the length of the current RLC SDU. Then, the next RLC header L stream is prefetched and copied to the L2 header stream at offset 8, and the next PDCP header stream is copied to the L2 header stream at offset 10.

[0085] Step 5: PDCP header parsing: Combine pdcp_entity_cfg to complete the parsing of the current PDCP header. Repeat steps 4 and 5 until all RLC PDUs in the current RLC PDU group have been parsed.

[0086] Step 6: Repeat steps 3, 4, and 5 until all RLC PDUs of the current MAC SDU have been parsed.

[0087] Step 7: Repeat steps 2, 3, 4, 5, and 6 until the protocol header parsing of all MACPDUs in the entire TB is completed.

[0088] Step 8: Repeat steps 2, 3, 4, 5, 6, and 7 to parse the protocol header of the next TB.

[0089] The parsing method provided in this embodiment can effectively support NR protocol header parsing hardening accelerator, enabling the same protocol header hardening accelerator to simultaneously support L2 protocol header parsing for both NR and LTE systems.

[0090] The parsing method provided in this embodiment can find the offset of each sublayer protocol header in the L2 protocol header bitstream (an optional example of the first offset position mentioned above). The offset of the MAC header in the L2 protocol header bitstream is 0, and the maximum length of the MAC header is 3 bytes; the offset of the RLC header com in the L2 protocol header bitstream is 3, and the maximum length of the RLC header com is 5 bytes; the offset of the RLC header L in the L2 protocol header bitstream is 8, and the maximum length of the RLC header L is 2 bytes; the offset of the PDCP header in the L2 protocol header bitstream is 10.

[0091] The parsing method provided in this embodiment of the disclosure <1> It can provide MAC header bitstream: maintain mac_header_tb_offset, initially 0, update mac_header_tb_offset according to the current mac_header_len after parsing each MAC SDU, prefetch MAC header bitstream, and copy MAC header bitstream to the position where the L2 protocol header bitstream offset is 0. <2> The RLC header stream can be provided by updating rlc_header_com_tb_offset and rlc_header_l_tb_offset based on total_mac_header_len, total_rlc_header_group_len, and rlc_entity_cfg, prefetching the RLC header com stream and RLC header L stream respectively, copying the RLC header com stream to the L2 protocol header stream at offset 3, and copying the RLC header L stream to the L2 protocol header stream at offset 8. <3> Provide PDCP header stream: Update pdcp_header_tb_offset according to rlc_sdu_len (length of SDU in RCL layer), prefetch PDCP header stream, and copy PDCP header stream to the position of L2 protocol header stream offset by 10.

[0092] The parsing method provided in this embodiment can reuse the MAC header stream for RLC PDU parsing within the same MAC SDU group, and can also reuse the MAC header stream copy and parsing result, eliminating the need for multiple copying and parsing operations. Similarly, for RLC PDU parsing within the same RLC PDU group, it can reuse the RLC header COM stream, and can also reuse the RLC header COM stream copy and parsing result, eliminating the need for multiple copying and parsing operations.

[0093] The parsing method provided in this embodiment integrates the parsing of LTE and NR protocol headers. Since the parsing rules are software programmable, LTE and NR can share a set of protocol header parsing hardware accelerators.

[0094] The parsing method provided in this embodiment can perform parallel processing of parsing the protocol header and copying the protocol header by prefetching the protocol header code stream, which can greatly save waiting time and improve parsing efficiency.

[0095] Figure 5 This is a schematic diagram of the structure of a parsing device provided in an embodiment of the present disclosure.

[0096] like Figure 5 As shown, the analytical apparatus 50 includes:

[0097] The first determining module 501 is used to determine a first offset position corresponding to a sublayer of the data link layer, wherein the first offset position is used to represent the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer.

[0098] The second determining module 502 is used to determine the information of the first protocol header based on the first offset position and the first bitstream.

[0099] Optionally, in some embodiments of this disclosure, the second determining module 502 is further configured to:

[0100] The second bitstream is determined based on the transport block (TB) of the data link layer, wherein the second bitstream is the bitstream corresponding to the first protocol header;

[0101] The information of the first protocol header is determined based on the first offset position, the first bitstream, and the second bitstream.

[0102] Optionally, in some embodiments of this disclosure, the second determining module 502 is further configured to:

[0103] The second bitstream is inserted into the first offset position of the first bitstream to obtain the third bitstream;

[0104] Based on the third bitstream, determine the information of the first protocol header.

[0105] Optionally, in some embodiments of this disclosure, the second determining module 502 is further configured to:

[0106] Determine the entity configuration parameters for the sub-layer;

[0107] The third bitstream is parsed based on the entity configuration parameters to obtain the information of the first protocol header.

[0108] Optionally, in some embodiments of this disclosure, the second determining module 502 is further configured to:

[0109] Determine the second offset position corresponding to the sublayer, wherein the second offset position is used to represent the offset position of the second bitstream in the TB of the data link layer;

[0110] The second bitstream is obtained from the TB of the data link layer based on the second offset position.

[0111] Optionally, in some embodiments of this disclosure, the second determining module 502 is further configured to:

[0112] When the sublayer is the Media Access Control (MAC) layer, the starting position in the Data Link Layer (TB) is determined as the second offset position corresponding to the MAC layer.

[0113] When the sublayer is the Radio Link Control (RLC) layer, the second offset position corresponding to the RLC layer is determined based on the length of the second code stream of the MAC layer and the total length of at least one second code stream of the RLC layer.

[0114] When the sublayer is the Packet Data Convergence Protocol (PDCP) layer, the second offset position corresponding to the PDCP layer is determined based on the length of the Service Data Unit (SDU) of the RLC layer.

[0115] It should be noted that the foregoing explanation of the parsing method embodiment also applies to the parsing device of this embodiment, and will not be repeated here.

[0116] In this embodiment, by determining the first offset position corresponding to the sublayer of the data link layer, where the first offset position represents the offset position of the first protocol header in the first bitstream, the first protocol header is the protocol header of the sublayer, the first bitstream is the bitstream corresponding to the second protocol header, and the second protocol header is the protocol header of the data link layer, the information of the first protocol header is determined based on the first offset position and the first bitstream. Since the first offset positions of each sublayer of the data link layer are obtained in advance, and the offset position of the first protocol header of the sublayer in the L2 protocol header bitstream is determined, it can effectively support subsequent pre-fetching of the sublayer protocol header bitstream, thereby enabling parallel processing of parsing the protocol header and copying the protocol header bitstream. This significantly saves the MIPS resources required for parsing processing and improves parsing efficiency and effectiveness.
