| |
| == How to Read This Document |
| |
| This is the Function Specification for the set of BSSAPP protocol modules. BSSAPP protocol modules are developed for the TTCN-3 Toolset with TITAN. |
| |
| == Scope |
| |
| The purpose of this document is to specify the content of the BSSAPP protocol modules. Basic knowledge of TTCN-3 <<_2, [2]>> and TITAN TTCN-3 Test Executor <<_3, [3]>> is valuable when reading this document. |
| |
| = General |
| |
| Protocol modules implement the message structures of the related protocol in a formalized way, using the standard specification language TTCN-3. This allows defining of test data (templates) in the TTCN-3 language <<_2, [2]>> and correctly encoding/decoding messages when executing test suites using the Titan TTCN-3 test environment <<_3, [3]>>. |
| |
| The protocol modules are using Titan’s RAW encoding attributes <<_4, [4]>> and hence they are usable with the Titan test toolset only. |
| |
| = Functional Specification |
| |
| == Protocol version implemented |
| |
| This set of protocol modules implements protocol messages and constants of the BSSAPP protocol. The modules are based on 29.018 V7.3.0 (see <<_1, [1]>>). |
| |
| === Unimplemented Messages, Information Elements and Constants |
| |
| None. |
| |
| [[protocol-modifications-deviations]] |
| === Protocol Modifications/Deviations |
| |
| None. |
| |
| [[encoding-decoding-and-other-related-functions]] |
| == Encoding/Decoding and Other Related Functions |
| |
| This product also contains encoding/decoding functions, which assure correct RAW encoding of messages when sent from Titan and correct RAW decoding of messages when received by Titan. Implemented encoding/decoding functions: |
