4 General
V2X application includes V2V application, V2I application, V2N application and V2P application.
V2V application refers to the interaction of V2V application message between neighboring on-board UEs, and the message interaction is based on broadcast mode, for which the direct mode between UEs or the methods of the exchange of messages between UEs via infrastructure (e.g. RSU, application server) may be adopted.
V2I application means that the on-board UE sends V2I application message to RSU or local application server, and RSU or local application server sends V2I application message to the on-board UE.
V2N application refers to the communication between the UE and the application server over the EPS network.
V2P application refers to the interaction of V2P application message between on-board UE and human-held UE. For message interaction, the direct mode between UEs or the methods of the exchange of messages between UEs via infrastructure (e.g. RSU, application server) may be adopted.
LTE-based Vehicle-to-Everything wireless communication system supports V2V application, V2I application, V2N application and V2P application, which can be used to provide users with various services such as road safety, traffic efficiency improvement and infotainment. Application scenarios and requirement analysis of LTE-based Vehicle-to-Everything are given in Annex A.
5 General service requirements of LTE-based Vehicle-to-Everything
5.1 Basic requirements
Requirement 1: when the sending terminal is served by E-UTRAN supporting V2X, the message transmission shall be controlled by 3GPP network.
Requirement 2: when the V2X terminal is not served by E-UTRAN network supporting V2X, it shall be able to support and use 3GPP network to preconfigure system parameters for sending and receiving messages.
Requirement 3: whether served by E-UTRAN network supporting V2X, the V2X terminal shall be able to send and receive messages.
Requirement 4: RSU shall be able to send messages to and receive messages from the V2X terminal.
Requirement 5: 3GPP system shall support the communication between V2X terminals regardless of whether the V2X terminals belong to the same PLMN.
Requirement 6: 3GPP system shall be able to provide a method to change the priority of messages between V2X terminals.
Requirement 7: 3GPP system shall be able to provide a method to change message priority according to message type (security type or other type).
Requirement 8: 3GPP system shall be able to provide a method to change transmission rate and distance according to service conditions (such as terminal speed and terminal density).
Requirement 9: 3GPP system shall be able to support efficient distribution of information to a large number of V2X terminals.
Requirement 10: the V2X terminal shall be able to judge whether the current E-UTRAN network supports V2X communication.
