Intelligent transport system technology co-existence method and arrangement

A node for communication within a cooperative intelligent transport system, comprising:

• a processor;
• and
• memory, the memory comprising instructions executable by the processor whereby the processor is operative to,
• receive a first intelligent transport system message from another node of said cooperative intelligent transport system, and
• identify a technology status of said another node, wherein said technology status comprises information whether or not said first intelligent transport system message was transmitted configured according to a predetermined first intelligent transport system technology, and wherein said technology status further comprises information whether or not said first intelligent transport system message comprises a dual technology indicator in a layer above the transport layer, said dual technology indicator being an information element identifying that the node transmitting the first intelligent transport system message is capable of communicating intelligent transport system messages according to said first intelligent transport system technology as well as according to a predetermined second intelligent transport system technology.
