The OSS NAS Tools for C++ is an add-on to the OSS ASN.1/C++ Tools, and provides C++ access to the OSS NAS Tools for C. The OSS NAS Tools for C facilitates the creation of user applications that produce, encode, decode, and process messages conforming to 3GPP TS 24.501 (Non-Access-Stratum protocol). This version of the OSS NAS Tools for C++ supports 3GPP NAS version 15.6.0. Contact OSS Nokalva at firstname.lastname@example.org if you need to support a different version of NAS.
The tool consists of
The OSS NAS Tools for C++ API (application program interface) is a collection of functions and classes designed to be called by your application to encode, decode, and perform auxiliary operations on messages (or protocol data units) specified in 3GPP TS 24.501 (NAS) v.15.6.0.
Features of the OSS NAS Tools for C++ include
To use the API described in this document, you must include the provided C++ header file corresponding to the 3GPP NAS release version you plan to use: NAS5GS1560.h. You must also link your application with the OSS NAS Tools for C++ and ASN.1/C++ libraries. For example, to use the shared libraries on Linux, link with the libnascpp5GS1560.so import library and the libosscpp.so and libcpptoed.so ASN.1/C++ libraries. The resulting application requires access to the dynamic libraries while running, so locate the libraries in the current directory or add their location to the LD_LIBRARY_PATH environment variable.
For more information about how to compile and link an application that uses the OSS NAS Tools for C++ API and for sample programs, see the /samples subdirectory included in your package.
The OSS NAS Tools for C++ is an OSS ASN.1/C++ Tools add-on. It uses the ASN.1/C++ runtime classes, for example, to access the components of a decoded message. Therefore, the ASN.1/C++ runtime must be installed on the same computer as the OSS NAS Tools for C++.
This documentation applies to the OSS NAS Tools for C++ for 5G v7.1.0 for 3GPP Release 15.6.0.
