Embodiment

[0039] figure 2 A schematic diagram of an MVB protocol conformance test codec based on a TTCN-3 test system provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the codec mainly includes: an encoding module of the MVB protocol and a decoding module of the MVB protocol;

[0040] Wherein, the encoding module is used to convert the test and test control symbol version 3TTCN-3 data type test data of the multifunctional vehicle bus MVB protocol specification into the byte stream data in the network transmission during the test process;

[0041] The decoding module is used to convert the data received from the system under test into TTCN-3 data type.

[0042] Further, before converting the TTCN-3 data type test data formulated by the MVB protocol specification into byte stream data in network transmission during the test process, it includes:

[0043] Construct the corresponding TTCN-3 data type according to the MVB protocol data message format;

Abstract

The invention discloses an MVB protocol consistency testing coder and decoder based on a TTCN-3 testing system. The MVB protocol consistency testing coder and decoder comprises a coding module and a decoding module. The coding module is used for converting testing data formulated according to the MVB protocol standard and of a control symbol version 3TTCN-3 data type into byte stream data of the tested system, and the decoding module is used for converting the data received from the tested system into data of the TTCN-3 type. By the adoption of the coder and decoder, an MVB protocol consistency test based on the TTCN-3 testing system is achieved.

Description

technical field [0001] The invention relates to the technical field of coding and decoding, in particular to an MVB protocol conformance testing codec based on a TTCN-3 testing system. Background technique [0002] TTCN-3: (Testing and Test Control Notation-3, Test and Test Control Notation Version 3), is a globally applicable standard test language maintained by ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute). The platform independence of TTCN-3 and its special test capabilities have made it widely used to define formal test sets for communication systems, such as GSM, 3G and Bluetooth protocols. [0003] The codec is an important part of the TTCN-3 test system. The so-called codec refers to the conversion between the data defined by the TTCN-3 data type and the actual byte stream data transmitted by the network protocol. The purpose of this is In order to enable the test system and the system under test to identify t...
