Use any ASN.1 syntax

OneBuilder is able to work with any ASN.1 Syntax. Once configured OneBuilder can build and decode messages according to any ASN.1 syntax. (list of currently supported syntaxes). Additional syntaxes can be added on request at short notice.

The following diagram shows the message definition process from the standards bodies through to an encoded message. The appropriate standards bodies are responsible for creating the ASN.1 definition of a message set. This definition is then used to create a configuration for OneBuilder so that it can then encode and decode messages defined by the ASN.1 syntax.

Easy to use

OneBuilder is operated through familiar Windows® user interface controls. No programming or training is required.

To create a new message, you select from a list of available ASN.1 syntaxes and then select from a list of available messages defined by the syntax. On initialization, all mandatory fields are automatically created. The overall message structure is displayed in a tree format with the currently included fields highlighted.

You can then select any field and modify its value. All available options are displayed. Optional fields can be included or excluded and the length of variable length fields specified.

Information on the field’s name, range, and value are displayed. All data is checked for validated when entered. If an incorrect value is entered, immediate feedback is given.

For enumerated fields, all valid values are displayed in a drop down list.

Input and Output

OneBuilder can save the created message in either binary or ASCII format. The data is encoded as the message is being saved. The file format used is simple and can easily be read by other applications. More detailed information is available on request.

Typical Applications
Applications involving ASN.1 include:
  • 3GPP Layer 3 Protocols (NBAP, RRC, RANAP, RNSAP)
  • Secure Electronic Transaction Protocol (SET)
  • Z39.50 Information Retrieval Protocol and Wide Area Information Server (WAIS)
  • H.225.0 Call signalling protocols and media stream packetization for packet-based multimedia communication systems
