Intelligent Transport Systems (ITS); Cross Layer DCC Management Entity for operation in the ITS G5A and ITS G5B medium
|Publication Date:||1 June 2015|
The present document specifies the functionality of the decentralized congestion control (DCC) entity residing in the management plane for the ITS-G5A, ITS-G5B, and ITS-G5D radio interfaces, collectively known as the 5 GHz ITS frequency band.
The purpose of the DCC operation is to evaluate the load of the active radio channels and to optimize the radio channel usage by managing the ITS-S DCC parameters. Another purpose is to keep track and help the exchange of DCC parameters which cannot be conveyed via the data plane between the different layers.
The present document specifies:
- The necessary support functions of DCC that needs to be in the management plane, i.e. cross-layer DCC operations.
- The required interface parameters between the DCC management entity and the DCC entities in the facilities, the networking & transport and the access layers.
- The testing procedures and corresponding test cases.
