V2X communication is provided with two operation modes: PC5-based V2X communication and LTE-Uu-based V2X communication. Wherein, the latter may be unicast or broadcast. The V2X equipment may receive and send messages using the two operation modes respectively. Example: a V2X equipment may receive V2X messages using downlink broadcast of LTE-Uu, but send V2X messages without using LTE-Uu. A V2X equipment may also receive V2X messages via LTE-Uu downlink unicast. The V2X communication is based on PC5 reuses one-to-many ProSe for direct communication transmission procedure. The PC5-U protocol stack as defined in proximity communication is used for the V2X communication transmission based on PC5 interface. The general technical requirements of security for V2X communication based on PC5 and LTE-Uu are prepared in this standard. 4.2 V2X communication architecture based on PC5 and LTE-Uu 4.2.1 V2X communication architecture based on PC5 and LTE-Uu in non-roaming scenarios Figure 1 shows the V2X communication architecture based on PC5 and LTE-Uu in non-roaming scenarios. Figure 1 V2X communication architecture based on PC5 and LTE-Uu in non-roaming scenarios 4.2.2 V2X communication architecture based on PC5 and LTE-Uu in roaming scenarios Figure 2 shows the V2X architecture based on PC5 and LTE-Uu in roaming scenarios, V2X equipment A home PLMNA, V2X equipment B home PLMNB, V2X equipment A roaming to PLMNB, and V2X equipment B non-roaming. The V2X application server may be connected to multiple PLMNs. Example: a V2X application server may be connected to V2X control function entities in PLMN A or those in PLMN B. Figure 1 V2X communication architecture based on PC5 and LTE-Uu in roaming scenarios 4.2.3 V2X communication architecture based on PC5 and LTE-Uu in cross-PLMN scenarios Figure 3 shows the V2X architecture based on PC5 and LTE-Uu in cross-PLMN roaming scenarios, V2X equipment A home PLMN A, V2X equipment B home PLMN B, V2X equipment A roaming to PLMN C, and V2X equipment B non-roaming. Figure 3 V2X architecture based on PC5 and LTE-Uu in cross-PLMN scenarios 4.2.4 Reference point Reference points of V2X communication architecture based on PC5 and LTE-Uu contain: ——V1: the reference point between the V2X application (in the V2X equipment) and the V2X application server. ——V2: the reference point between the V2X application server and V2X control function. The V2X application server may be connected to multiple V2X control functions belonging to PLMN. ——V3: the reference point between the V2X equipment and the V2X control function in home PLMN. It is applicable to V2X communication based on PC5 and LTE-Uu; the V2X communication based on LTE-Uu may support MBMS optionally. ——V4: the reference point between the HSS and the V2X control function in the operator's network. ——V5: the reference point between the V2X applications of different V2X equipment. ——V6: the reference point between the V2X control functions in different PLMNs. ——PC5: the reference point for ProSe direct communication in user plane between the V2X equipment using V2X service. ——S6a: in the V2X scenario, MME can download subscription information related to V2X communication during E-UTRAN attach procedure or to inform the subscription information in the HSS to MME when the information is changed. ——S1-MME: in the V2X scenario, the reference point is used to send the V2X service authorization from MME to eNodeB. ——LTE-Uu: the reference point between the UE and the E-UTRAN. 4.3 V2X communication architecture based on MBMS and LTE-Uu Figure 4 shows the V2X communication architecture based on MBMS and LTE-Uu.
