Figure 4.2.1.2-1 and
Figure 4.2.1.2-2 show the high level view of the roaming 5G System architectures for V2X communication over PC5 and Uu reference points. In these Figures, UE A uses a subscription of HPLMN.
In the case of inter-PLMN V2X communication over PC5 reference point, the PC5 parameters need to be configured in a consistent way among the UEs within a certain region. The architecture for the Inter-PLMN PC5 case is similar to the one defined in
clause 4.2.1.1.
