Architecture model and concepts
General concept
4.1
There are two modes of operation for V2X communication, namely over the PC5 and over LTE-Uu. LTE-Uu can be
unicast and/or MBMS. These two operation modes may be used by a UE independently for transmission and reception,
e.g. a UE can use MBMS for reception without using LTE-Uu for transmission. A UE may also receive V2X messages
via LTE-Uu unicast downlink.
For both operation modes, the following principles apply:
- V2X Application Servers e.g. in different domains can communicate with each other for the exchange of V2X
messages. The interface between V2X Application Servers and the methods of the exchange of messages
between V2X Application Servers is out of scope of 3GPP.
- ProSe discovery feature (TS 23.303 [5] clause 5.3 ProSe Direct Discovery) is not required for V2X Services.
NOTE:
ProSe discovery feature can be used by a V2X supporting UE, but that is up to UE implementation.
- Subject to regional regulations, lawful interception requirements apply to V2X Services.
- An RSU is not an architectural entity, but an implementation option. This is achieved by collocating a V2X
application logic/server with some entities of the 3GPP system, as shown in examples in Annex A.
