OSS Nokalva Announces 3GPP NAS Productivity Tools

SOMERSET, NJ--(Marketwire - Apr 18, 2012) - OSS Nokalva, Inc. announced today its new 3GPP NAS Productivity Tools.

OSS Nokalva has developed a set of productivity enhancing tools that free customers from the time consuming and error prone task of writing software to create, process, debug and test NAS (Non-Access-Stratum) protocol (3GPP TS 24.301) messages. The new tools are the OSS NAS Encoder/Decoder Library, and the OSS NAS-1Step application.

The NAS Encoder/Decoder Library, available on Windows for C and C++, is a tool that facilitates the creation, encoding, decoding, and processing of messages conforming to the 3GPP Technical Specification 24.301. The library takes care of all of the unique aspects of NAS message serialization such as, required and optional information elements, bit-level format of each type of information element, bit order, half-octet order, and so on. A developer using the library works with a set of C structures or C++ classes provided with the library, and makes simple calls to encode and decode functions, as well as to other useful functions which are available. The NAS Encoder/Decoder Library API supports:

  • Encoding and decoding NAS protocol data units.
  • Printing encoded or un-encoded NAS protocol data units in XML form.
  • Copying NAS protocol data units.
  • Comparing un-encoded or decoded NAS protocol data units.

Current users of OSS' ASN.1 C or C++ Tools will feel at home with this API because both the API and the C structures and C++ classes are very similar to those used with protocols specified in ASN.1.

OSS' NAS-1Step is a Windows application that enables you to interactively create, view, and edit messages conforming to the 3GPP Technical Specification 24.301. NAS-1Step is a useful tool for anyone working with the NAS protocol, from system designers to application developers and testers. It can be used for a range of activities, including displaying a NAS message in a collapsible tree-view, editing a NAS message, creating a set of NAS messages for testing purposes, and so on, and allows one to work simultaneously with messages belonging to multiple versions of the NAS protocol (multiple 3GPP releases). NAS-1Step provides several functions including:

  • A text viewer that displays a description of the structure of NAS messages in a formal notation (ASN.1) and supports both syntax coloring and syntax-aware navigation.
  • A message viewer/editor able to load an encoded message from a file, decode the message, create a new message, make changes to a message, re-encode it, and save it.
