• Many formatting options
• Generation of summary tables describing the schema
• Microsoft Word compatibility

OSS Nokalva announces the availability of the ASN.1 Tools for C version 10.6, ASN.1 Tools for C++ version 6.6, ASN.1 Tools for Java version 7.2, ASN.1 Tools for C# version 4.6, and ASN-1Step version 8.3. These releases include new features, as follows:

• All ASN.1 products
  • Support for the Canonical Packed Encoding Rules (ALIGNED and UNALIGNED) as specified by ITU-T Recommendation X.691 (08/2015) | ISO/IEC 8825-2:2015 has been added.
  • The ASN.1 compiler supports the UPPERCAMELCASED and LOWERCAMELCASED keywords in the NAME and TEXT JER encoding instructions. You can now describe a wider range of JSON data in an ASN.1 schema.
  • New samples have been created for 3GPP Release 14 of the LTE protocols (including RRC, S1, X2, and LPPa) and the existing Release 12 and 13 samples have been updated to the most recent versions of the ASN.1 schemas.
  • Improved ASN.1 Studio.
• ASN.1/C
  • The JSON encoders will now always encode a non-special REAL value as a JSON number. Previously, it could be encoded as a JSON object. For example, value 3.14 of an unconstrained REAL type was encoded as {base10value: 3.14}. The JSON decoders now accept both encoding forms: JSON number and JSON objects.
  • The DER/CER/CXER/COER encoders now automatically convert any valid value of GeneralizedTime and UTCTime types to the canonical form specified by X.690 Clause 11.7 and 11.8. Previously it was assumed that the value to be encoded already satisfied the restrictions imposed on its encoding by these clauses. For example, the UTCTime value "171231235900Z" was accepted but "17122359Z" was rejected because the seconds component was absent.
  • A new sample that demonstrates processing of CDR files as described by 3GPP TS 32.297 has been added.
• ASN.1/C++
  • The JSON encoders will now always encode a non-special REAL value as a JSON number. Previously, it could be encoded as a JSON object. For example, value 3.14 of an unconstrained REAL type was encoded as {base10value: 3.14}. The JSON decoders now accept both encoding forms: JSON number and JSON objects.
  • The DER/CER/CXER/COER encoders now automatically convert any valid value of GeneralizedTime and UTCTime types to the canonical form specified by X.690 Clause 11.7 and 11.8. Previously it was assumed that the value to be encoded already satisfied the restrictions imposed on its encoding by these clauses. For example, the UTCTime value "171231235900Z" was accepted but "17122359Z" was rejected because the seconds component was absent.
• ASN.1/Java
  • Both the compiler and runtime have been enhanced to support the JPMS (Java Platform Module System), which was introduced in Java 9. The compiler now supports the '-javamodule <name>' option that packages the generated classes into a Java module with the specified <name>. The software distribution now includes an extra set of runtime libraries that are packaged as Java 9 modules. These new libraries are available in the mlib/ directory of the ASN.1/Java installation and can be used only with JDK 9.
  • The public API of the JIAAPI value parser will now parse concatenated values and value assignments from an arbitrary java.io.Reader object. A relaxed parsing mode has been implemented: now non-critical deviations from the expected syntax are ignored.
  • A new sample that demonstrates processing of 3GPP CDR files (TS 32.297) has been created.
  • A new sample for release 14.4.0 of the UMTS RRC protocol (TS 25.331) has been created.
• ASN-1Step
  • ASN-1Step will now accept any valid value of GeneralizedTime and UTCTime types and will encode it according to X.690 Clause 11.7 and 11.8. Previously, it was assumed that the input value already satisfied the restrictions imposed on its encoding by these clauses. Therefore
    • All encoders reported an error if the time differential was present in the input value.
    • The DER/CER/COER encoders reported an error if the input value represented as a NULLTERM string did not contain the minutes or seconds component.
  • The XER and E-XER encoders now encode any valid NULLTERM values of GeneralizedTime and UTCTime types without making additional changes. Previously, when the input value did not contain a minutes or seconds component, the encoders unnecessarily included a zero minutes or seconds component in the encoding and recalculated the fractional part, if any.
  • The JSON encoders will now always encode non-special REAL values as JSON numbers. The JSON decoders will accept both encoding forms: JSON number and JSON object encodings. Previously, non-special REAL values could be encoded as JSON objects. For example, an unconstrained REAL type value was encoded as {base10value: N } The decoders reported an error when such values were encoded as JSON numbers.

The OSS® ASN.1 LTE solutions go beyond support for low-level ASN.1 development. They build upon the robust, and reliable OSS ASN.1 Tools for C, offering several APIs that ease the implementation of 3GPP LTE S1, X2, and now LPPa protocols.

As the world of communication expands at an ever increasing rate, as the messages communicated are becoming more complex, and as the proper interpretation of the content of such messages becomes more critical, the need for a schema becomes more important.

The goal of ASN1.IO is to offer a familiar, JSON-like development experience to developers whose applications would benefit from the use of a schema.

ASN.1 IO currently offers three web applications: the ASN.1 Playground, the Schema Analyzer, and the JSON2ASN converter.

OSS Nokalva announces the availability of the ASN.1 Tools for C version 10.5, ASN.1 Tools for C++ version 6.5, ASN.1 Tools for Java version 7.1, ASN.1 Tools for C# version 4.5, and ASN-1Step version 8.2. These releases include new features, as follows:

• All ASN.1 products
  • Conformance to Draft ITU-T Recommendation X.jsoner:
    • The ASN.1 compiler and runtime libraries support the JSON Encoding Rules. The existing -json command-line option instructs the compiler to enable support for X.jsoner at runtime.
    • The JSON codec supports the following encoding instructions:
      • JER:ARRAY
      • JER:BASE64
      • JER:NAME
      • JER:OBJECT
      • JER:TEXT
      • JER:UNWRAPPED
  • The following new samples for LTE protocols have been added:
    
    • The LTE LCS-AP sample demonstrates the TS 29.171 V13.2.0 (2016-03) LCS Application Protocol.
    • The LTE LPPa sample demonstrates the TS 36.455 V13.1.0 (2016-03) LTE Positioning Protocol A.
    • The LTE RRC C-V2X sample demonstrates the Sidelink feature of the TS 36.331 V14.2.2 (2017-03) LTE RRC Protocol.
  • Improved ASN.1 Studio.
• ASN.1/C and ASN.1/C++
  • Smaller TOED footprint. By defining OSS_REDUCED_ERROR_MSGS when compiling the generated .c or .cpp, error messages will contain just the 5 character message prefix, instead of the full message. Alternatively, if OSSDEBUG=0 is defined, the error message strings will be removed completely, leaving only the return code to determine which error occurred. On Linux x86, you can reduce the footprint of your application by approximately 20 kilobytes. This number may vary depending on the processor, operating system, and C compiler.
• ASN.1/C#
  • Includes an additional version of the runtime assembly compatible with .NET Standard 1.4. You can use this version of the asn1csrt.dll runtime DLL to develop applications on the following platforms:
    • .NET Core 1.0 on Windows, macOS, Linux
    • UWP 10.0
    • Xamarin
    To generate C# classes compatible with .NET Standard, specify the -noserializable compiler option.
• ASN-1Step
  • Supports 3GPP CDR files with messages encoded using various encoding rules that are specified inside record headers. Currently the BER, PER, UPER, and XER encoding rules are supported.
