Description

[0002] Abstract Syntax Notation One (ASN.1) describes a data format for representing, encoding, transmitting, and decoding data. In actual use, developers need to convert the ASN.1 abstract syntax into a language recognizable by a computer (such as C / C++, Java, etc.). Currently, in the process of encoding sequence data based on ASN.1, it is mainly determined whether there are extension items through the flag bit information corresponding to the sequence data. If so, the extension items need to be encoded.

[0003] However, for extension items without filled data, the flag bit information will also indicate the existence of extension items in the sequence data, which will cause the encoding of extension items without data filling during the encoding process, resulting in the inclusion of invalid data in the data bitstream, increasing the invalid data in the bitstream and reducing the encoding efficiency.

[0048] Embodiments of the present application will be described in more detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0049] In order to improve the current technical problem that during the encoding process, an extension item without data filling is encoded, resulting in invalid data being incorporated into the data bitstream, increasing the invalid data in the bitstream and reducing the encoding efficiency. This embodiment provides a data encoding method, as Figure 1 shown, the method includes:

[0050] Step 101, obtain first sequence data to be encoded including extension item information.

[0051] Among them, the extension item information corresponds to the pointer type.

[0052] In the embodiments of the present application, a sequence is the most basic data type in a computer programming language (Python). Each element in the sequence has a number, that is, the position of the element or what is called the index. The index value of the first element is 0, the index value of the second element is 1, and so on. Lists, tuples, and strings in Python all belong to sequences. Among them, a list is mutable (the elements in it can be modified), and tuples and strings are immutable (once created, the content is fixed).

[0053] Optionally, a pointer is an object in a programming language. Using the address, its value directly points to the value in another place in the computer memory. Since the variable unit can be found through the address, it can be said that the address points to the variable unit. Therefore, the address is vividly called a "pointer", and through it, the memory unit with its address can be found. A pointer refers to a certain address in the memory. By an action called dereferencing the pointer, the value stored at that address can be retrieved.

[0054] In some instances, the extension item information may be other extended data information in the first sequence data to be encoded except for the basic data. For example, the first sequence data to be encoded includes data 1, data 2, data 3, and data 4. Among them, data 1 may be the basic data in the first sequence data to be encoded, and data 2, data 3, and data 4 may be the extended data in the first sequence data to be encoded.

[0055] Step 102: Analyze the extended item information to determine whether there is pointer information in at least one extended item included in the extended item information.

[0056] Among them, the pointer information is used to indicate that there is padding data in the extended item.

[0057] Optionally, the pointer information can be the address information of the extended item. For example, the first sequence data to be encoded contains data 1, data 2, data 3, and data 4. Among them, data 2, data 3, and data 4 can be the extended information in the first sequence data to be encoded. If data 2 corresponds to extended item 2, it can be determined whether there is corresponding pointer information in extended item 2. If so, it can be determined that there is padding data in extended item 2.

[0058] Correspondingly, if data 3 corresponds to extended item 3, it can be determined whether there is corresponding pointer information in extended item 3. If there is no corresponding pointer information in extended item 3, it can be determined that there is no padding data in extended item 3, and so on. Examples are not given one by one here.

[0059] Step 103: If there is a target extended item without pointer information in at least one extended item, encode the second sequence data to be encoded in the first sequence data to be encoded except for the target extended item.

[0060] In the embodiment of the present application, the second sequence data to be encoded is the second sequence data obtained after removing the extended items without padding data from the first sequence data to be encoded.

[0061] For this embodiment, the target extended item can be an extended item without pointer information. For example, if extended item 2 and extended item 4 do not contain pointer information, then extended item 2 and extended item 4 are target extended items.

[0062] Furthermore, when encoding the first sequence data to be encoded, it is necessary to remove the target extended item to obtain the second sequence data to be encoded, and then encode the second sequence data to be encoded.

[0063] For example, the first sequence data to be encoded contains data 1, data 2, data 3, and data 4. Among them, data 2 corresponds to extended item 2, data 3 corresponds to extended item 3, and data 4 corresponds to extended item 4. If extended item 2 and extended item 4 do not contain pointer information, then extended item 2 and extended item 4 are target extended items. When encoding data 1, data 2, data 3, and data 4, it is necessary to remove extended item 2 and extended item 4, that is, encode data 1 and data 3.

[0064] Compared with the current existing technologies, in this embodiment, the first sequence data to be encoded is determined as a pointer type, and the pointer information is used to specifically determine whether there is padding data in each extension item. If there is an extension item that does not contain padding data, the extension item that does not contain padding data is removed from the first sequence data to be encoded, and the second sequence data is obtained and then encoded. This can accurately identify whether the extension item actually exists, avoid encoding invalid data such as the quantity, length field, and identification bit related to the extension item, reduce the transmission of invalid data between networks, and further avoid the decoder from decoding the invalid data, thereby improving the encoding efficiency.

[0065] To further illustrate the specific implementation process of the method in this embodiment, this embodiment provides a specific method as shown in Figure 2 which includes:

[0066] Step 201: Obtain ASN.1 data and input the ASN.1 data into a data structure generator for conversion processing.

[0067] Among them, the data structure generator is set to determine the extension item information as a pointer type if the ASN.1 data contains extension item information.

[0068] In the embodiment of the present application, Abstract Syntax Notation One (ASN.1) describes a data format for representing, encoding, transmitting, and decoding data, provides a set of formal formats for describing the structure of objects, regardless of how they are implemented linguistically and what these data specifically refer to, and regardless of what kind of application program it is.

[0069] Optionally, the conversion processing is to convert the ASN.1 data into a language recognizable by a computer. For example, if the ASN.1 data corresponds to data 1 in format 1, it needs to be converted into data 1 in format 2 through the data structure generator.

[0070] In the embodiment of the present application, the ASN.1 data needs to be converted into sequence data.

[0071] It should be noted that if the ASN.1 data has extension item information, the extension item information needs to be determined as a pointer type during the conversion process.

[0072] For this embodiment, if the ASN.1 data does not contain extension item information; correspondingly, after step 201, the method in this embodiment further includes: obtaining the third sequence data to be encoded that does not contain extension item information based on the processing result of the conversion processing.

[0073] Exemplarily, if the third sequence data to be encoded does not contain extension item information, it is not necessary to determine the third sequence data to be encoded as a pointer type.

[0074] In the embodiment of the present application, after step 201, the method of this embodiment further includes: setting the flag bit information of the third sequence data to be encoded to indicate that there is no extension item information in the third sequence data to be encoded; encoding the third sequence data to be encoded based on the flag bit information of the third sequence data to be encoded.

[0075] For this embodiment, the flag bit information can be one bit (bit) indicating whether there is an extension item.

[0076] The third sequence data to be encoded without extension item information can be directly encoded.

[0077] Step 202: Obtain the first sequence data to be encoded that contains extension item information.

[0078] Among them, the extension item information corresponds to the pointer type.

[0079] Optionally, if the ASN.1 data contains the extension item information, correspondingly, step 202 may specifically include: obtaining the first sequence data to be encoded that contains extension item information based on the processing result of the conversion process.

[0080] Exemplarily, in the ASN.1 data, “...” can be used to indicate that the sequence data supports extensions, and there are 0 or more extension item data thereafter. The rate “[[ ]]” can be used to indicate that the data between them is an extended data of the same version extension.

[0081] For example, the extension item can be expressed as: “[[extention 1]]”, “[[extention 2]]” and so on, and no more examples are given here.

[0082] In some examples, after step 202, the method of this embodiment further includes: setting the flag bit information of the first sequence data to be encoded to indicate that there is extension item information in the first sequence data to be encoded; and storing corresponding padding data in at least one extension item of the first sequence data to be encoded.

[0083] For this embodiment, the first sequence data to be encoded includes Data 1, Data 2, Data 3, and Data 4. Among them, Data 2 corresponds to Extension Item 2, Data 3 corresponds to Extension Item 3, and Data 4 corresponds to Extension Item 4. By filling data into Extension Item 2, Extension Item 3, and Extension Item 4, the filled Extension Item 2, Extension Item 3, and Extension Item 4 can be obtained.

[0084] It should be noted that since there are extension item data in the first sequence data to be encoded, first, the length of the number of extension items is encoded, and then for each extension item, there is one bit as an indication to encode whether the extension item exists; finally, each "[[]]" extension item is encoded as an open type (including a data length field and data encoding).

[0085] Step 203: Analyze the extension item information to determine whether at least one extension item included in the extension item information has pointer information.

[0086] Among them, the pointer information is used to indicate that there is filled data in the extension item.

[0087] Exemplarily, based on Step 202, each of Extension Item 2, Extension Item 3, and Extension Item 4 is analyzed to determine whether there is corresponding indication information.

[0088] Step 204: If at least one extension item includes a target extension item without pointer information, then encode the second sequence data to be encoded in the sequence data to be encoded except for the target extension item.

[0089] Optionally, Step 204 may specifically include: if at least one extension item includes a target extension item without pointer information, mark the first identifier for the target extension item; determine at least one target extension item marked with the first identifier information.

[0090] Among them, the first identifier is used to identify the extension item without filled data.

[0091] In the embodiment of the present application, the first identifier may be an identifier for the extension item without filled data. Exemplarily, if there is no filled data in Extension Item 2, then mark the first identifier for Extension Item 2 and determine that Extension Item 2 is the extension item without filled data. If there is no filled data in Extension Item 4, then mark the first identifier for Extension Item 4 and determine that Extension Item 4 is the extension item without filled data, and so on. Examples are not given one by one here.

[0092] In some examples, step 204 specifically further includes: processing the first sequence data to be encoded based on at least one target extension item to obtain second sequence data to be encoded; setting the flag bit information of the second sequence data to indicate that there is extension item information in the second sequence data to be encoded; and encoding the second sequence data to be encoded based on the flag bit information of the second sequence data to be encoded.

[0093] Optionally, the flag bit information may be an indication flag indicating the existence or non-existence of an extension item. All IEs in a "[[]]" are recorded in a structure, and a pointer is used to record the extension item data, which not only simplifies the description of the extension item data of the same version but also makes it easier for the encoder to identify misplacement of the extension item indication bit.

[0094] Exemplarily, based on step 203, if it is determined that extension item 2 and extension item 4 are extension items without padding data, then extension item 2 and extension item 4 are removed from the first sequence data to be encoded to obtain second sequence data to be encoded, and encoding processing is performed on the second sequence data to be encoded.

[0095] In the embodiment of the present application, after step 204, the method of this embodiment further includes: if at least one extension item included in the extension information has pointer information, setting the flag bit information of the first sequence data to be encoded to indicate that there is extension item information in the first sequence data to be encoded; and encoding the first sequence data to be encoded based on the flag bit information of the first sequence data to be encoded.

[0096] It should be noted that if all extension items in the first sequence data to be encoded have padding data, then the first sequence data to be encoded is encoded.

[0097] In the current prior art, according to the asn.1 protocol, the extension item data enclosed by a "[[]]" should be encoded as an open type. The technology provided in 1 requires recording in the attribute record table which IEs belong to an extension item, increasing the complexity of data description and the consumption of the memory static storage area.

[0098] When there are extended items mis-set in the bit_mask but no data is filled in the actual extended items, complex logic is required to determine whether there is valid data in the extended items that needs to be encoded. At the same time, it is very difficult to determine whether the extended item data of types such as INTEGER and BOOLEAN is actually filled. Therefore, when an extended item IE in the bit_mask is mis-set but no actual data is filled, it may cause invalid data (invalid data such as the extended quantity field and length field) to be encoded into the data bitstream, increasing the transmission of data (part of which is invalid data) over the network. At the same time, the communication peer at the other end will decode the invalid bitstream, reducing the decoding efficiency.

[0099] Compared with the current existing technologies, in this embodiment, the data of the first sequence to be encoded is determined as a pointer type, and it is specifically determined whether there is filled data in each extended item through the pointer information. If there is an extended item that does not contain filled data, the extended item that does not contain filled data is removed from the data of the first sequence to be encoded, and the second sequence data is obtained and then encoded. It can accurately identify whether the extended item actually exists, and avoid the encoding of invalid data such as the quantity, length field, and identification bit related to the extended item, reducing the transmission of invalid data between networks. Furthermore, it can avoid the decoder from decoding invalid data. When there is no extended item data, it only occupies the size of a pointer, which can save the memory space of the device. It solves the problem that when the existence indication of the extended item in the sequence is set, but there is no extended item data, the bitstream of the sequence data will not encode the extended item quantity field bitstream that is useless to the user, the length field of the set extended item, or even the meaningless or incorrect data bitstream.

[0100] To illustrate the specific implementation process of this embodiment, the following specific application examples are given, such as Figure 3 shown, but not limited to this:

[0101] Design rules in the ASN.1 data structure generator to make the extended items in the sequence data structure be of pointer type; when there is extended item data in the sequence, in addition to setting the flag to TRUE, apply for memory to fill the data at the same time, and point the pointer corresponding to the extension to this block of memory; otherwise, set the pointer corresponding to the extended item to NULL.

[0102] During the encoding process of the sequence data, first determine whether there is an extended item with the flag set to TRUE. If there is no extended item with the flag set to TRUE, the encoder sets the flag indicating whether the extended item exists to 0 (indicating that there is no extended item data), and does not encode the extended item subsequently.

[0103] If there is an extended item marked as TRUE, continue to determine whether the corresponding extended item pointer is empty. If it is not empty, the encoder sets the flag indicating the existence of the extended item to 1 (indicating that there is extended item data), and subsequently encodes the identification field and data content of the extension; if there is an extended item marked as TRUE while the corresponding pointer is indeed empty, the encoder sets the flag indicating the existence of the extended item to 0 (indicating that there is no extended item data), and subsequently does not encode the extended item.

[0104] Compared with the current existing technologies, in this embodiment, by determining the first sequence data to be encoded as a pointer type, and specifically judging whether there is padding data in each extended item through the pointer information. If there is an extended item that does not contain padding data, the extended item that does not contain padding data is removed from the first sequence data to be encoded to obtain the second sequence data and then encoded. It can accurately identify whether the extended item actually exists, and avoid the encoding of invalid data such as the quantity, length field, and identification bit related to the extended item, reducing the transmission of invalid data between networks. Furthermore, it can avoid the decoder from decoding the invalid data; when there is no extended item data, it only occupies the size of one pointer, which can save the memory space of the device; it solves the problem that when the existence indication of the sequence extended item is set, but there is no extended item data, the bit code stream of the sequence data will not include the bit code stream of the extended item quantity field that is useless to the user, the length field of the set extended item, or even the meaningless or incorrect data bit code stream.

[0105] Further, as Figure 1 and Figure 2 a specific implementation of the method shown, this embodiment provides a data encoding device, as Figure 4 shown, the device includes: an acquisition module 31, an analysis module 32, and an encoding module 33.

[0106] The acquisition module 31 is configured to acquire the first sequence data to be encoded containing extended item information, and the extended item information corresponds to a pointer type;

[0107] The analysis module 32 is configured to analyze the extended item information to determine whether there is pointer information in at least one extended item included in the extended item information, where the pointer information is used to indicate that there is padding data in the extended item;

[0108] The encoding module 33 is configured to, if there is a target extended item in the at least one extended item that does not contain pointer information, encode the second sequence data to be encoded in the first sequence data to be encoded except the target extended item.

[0109] In some examples of this embodiment, the obtaining module 31 is further configured to obtain Abstract Syntax Notation One (ASN.1) data, and input the ASN.1 data into a data structure generator for conversion processing, where the data structure generator is configured to determine the extension item information as a pointer type if the ASN.1 data contains the extension item information.

[0110] In some examples of this embodiment, if the ASN.1 data contains the extension item information; correspondingly, the obtaining module 31 is specifically configured to obtain first sequence data to be encoded that contains the extension item information based on the processing result of the conversion processing.

[0111] In some examples of this embodiment, the obtaining module 31 is further configured to set the flag bit information of the first sequence data to be encoded to indicate that the extension item information exists in the first sequence data to be encoded; and store corresponding padding data in at least one of the extension items of the first sequence data to be encoded.

[0112] In some examples of this embodiment, if the ASN.1 data does not contain the extension item information; correspondingly, the obtaining module 31 is further configured to obtain third sequence data to be encoded that does not contain the extension item information based on the processing result of the conversion processing.

[0113] In some examples of this embodiment, the obtaining module 31 is further configured to set the flag bit information of the third sequence data to be encoded to indicate that the extension item information does not exist in the third sequence data to be encoded; and encode the third sequence data to be encoded based on the flag bit information of the third sequence data to be encoded.

[0114] In some examples of this embodiment, the encoding module 33 is further configured to, if a target extension item that does not contain pointer information exists in at least one of the extension items, mark the target extension item with a first identifier, where the first identifier is used to identify an extension item without padding data; and determine at least one of the target extension items marked with the first identifier information.

[0115] In some examples of this embodiment, the encoding module 33 is specifically configured to process the first sequence data to be encoded based on the at least one target extension item to obtain the second sequence data to be encoded; set the flag bit information of the second sequence data to indicate that the extension item information exists in the second sequence data to be encoded; and encode the second sequence data to be encoded based on the flag bit information of the second sequence data to be encoded.

[0116] In some examples of this embodiment, the encoding module 33 is further configured to, if pointer information exists for at least one extension item included in the extension information, set the flag bit information of the first sequence data to be encoded to indicate that the extension item information exists in the first sequence data to be encoded; and encode the first sequence data to be encoded based on the flag bit information of the first sequence data to be encoded.

[0117] It should be noted that for other corresponding descriptions of each functional unit involved in the data encoding device provided in this embodiment, reference can be made to Figure 1 and Figure 2 the corresponding descriptions therein, which will not be elaborated here.

[0118] Based on the above method as shown in Figure 1 and Figure 2 correspondingly, this embodiment further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the above method as shown in Figure 1 and Figure 2 is implemented.

[0119] Based on such an understanding, the technical solution of this application can be embodied in the form of a software product. The software product can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), and includes several instructions for causing a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods in various implementation scenarios of this application.

[0125] Through the description of the above embodiments, those skilled in the art can clearly understand that the present application can be implemented by means of software plus a necessary general hardware platform, or can also be implemented by hardware. By applying the solution of this embodiment, compared with the current prior art, in this embodiment, the first sequence data to be encoded is determined as a pointer type, and whether there is padding data in each extension item is specifically judged through pointer information. If there is an extension item that does not contain padding data, the extension item that does not contain padding data is removed from the first sequence data to be encoded, and the second sequence data is obtained and then encoded. It can accurately identify whether the extension item actually exists, and avoid the encoding of invalid data such as the quantity, length field, and identification bit related to the extension item, reduce the transmission of invalid data between networks, and thus avoid the decoder from decoding the invalid data; when there is no extension item data, it only occupies the size of one pointer, which can save the memory space of the device; it solves the problem that when the existence indication of the sequence extension item is set, but there is no extension item data, the bit stream of the sequence data will not encode the bit stream of the extension item quantity field that is useless to the user, the length field of the set extension item, or even the meaningless or incorrect data bit stream.

[0126] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
