Overview
TTsuite-China-ITS tests whether the signaling protocol layers of V2X equipment (OBUs and RSUs) conform to China CCSA and C-SAE test specifications for C-V2X communication over the LTE-V PC5 (C-V2X) RF interface.
V2X technology lets road traffic participants such as vehicles, infrastructure and pedestrians exchange messages about their type, size, position and heading. Applications on these devices use this information to improve road safety, for example to support Advanced Driving Assistance Systems (ADAS), or to monitor and optimize road traffic.
Interoperability is a key requirement for all C-V2X equipment that implements the signaling protocol stack. The suite uses automated test scripts to check that C-V2X protocols are implemented according to the standard specifications. This helps suppliers deliver interoperable C-V2X products. Test cases are written in the standardized TTCN-3 test notation, and vendor-specific test cases can be added.
Key Features
- Tests that V2X and C-V2X communications comply with standards
- Test metrics focused on precision, repeatability and safety
- Designed to reduce costly and time-consuming field testing
- Network layer test cases: DSM message transmission and reception
- Network layer test cases: DSA message transmission and reception
- Application layer test cases for BSM, MAP, RSM, SPAT and RSI message sets
- Full test automation via Test Control Interface
- Freely combinable with additional test access (TTplugins)
- Optional C-V2X LTE-V modem hardware device as radio proxy
- Supports vendor-specific test cases beyond standard specifications
