Alternatively, this instruction information can also include: reporting interface-free resources to indicate information, wherein, interface-free resources refers to
The up Uu mouth resource of UE to eNB, this resource is a resource pool, and resource therein is used for transmitting V2I information.
It is pointed out that this resource indication information for OBU from the scene of main separation resource, if use RSU scheduling money
Source, then RSU need not prior Resources allocation pond, when OBU sends request, RSU is OBU Resources allocation.
Report interface-free resources and the interface-free resources separate configuration for V2V/V2P, i.e. V2I ascending resource and V2V/V2P resource
Separate.
Resource pool can be indicated by one or more of information: T/F position/index, cyclic prefix CP length,
Cycle, modulation and encoding scheme MCS.
RSU arranges according to self-position or operator/service provider and determines " warning information reports instruction ", at RSU
There is skyscraper to block near overpass up/down or RSU or near RSU, the visual condition of road is poor or runs
Business/service provider requires that this RSU receives warning information, etc., then RSU determines that " warning information reports instruction " is true true,
Otherwise report and be designated as false false.
It should be noted that RSU can also set the condition of OBU report and alarm information, when the conditions are met, OBU
Report and alarm information, as when OBU is in ad-hoc location or in certain special time period or particular event is sent out
Time raw, OBU needs report and alarm information to RSU.
Additionally, RSU includes in instruction information: OBU directly reports RSU or reports V2X service center；Its
In, OBU directly reports RSU to use V2I mode, and OBU reports V2X service center to use application layer mode.
Broadcast uses existing system broadcast or new broadcast to realize, and this broadcasting periodic sends.
Step S702, OBU judges whether to send alarm business to RSU, if it is, turn to step S703, no
Then turn to step S705.
Wherein, OBU first detects alarm business, as road has vehicle to break down, congestion in road, has dense fog, road
Road maintenance etc., OBU needs the alarm information noticing detected to other vehicles closed on or pedestrian.Then,
OBU is according to the RSU broadcast message in step S801 received, it may be judged whether need to report RSU, such as step S801
It is true for being explicitly indicated " warning information reports instruction " in middle RSU broadcast instruction information, then OBU determines that needs will detection
To alarm business report RSU.
Step S703, OBU selects resource reporting RSU warning information.

Send V2I alarm business information, send and use unicast bearer, if OBU is connected state, then directly send to RSU,
If OBU is Idle state, then send a warning message to RSU again after initially entering connected state.
It is pointed out that when OBU is from main separation V2I interface-free resources, if there being two or more OBUs same
Time have selected identical resource and send service announcements, then there is resource request conflict.If it occur that conflict, general employing is sent out
The OBUs of raw conflict reselects resource after retreating random time again.
Step S704, RSU broadcast forwards warning information.
Wherein, RSU receives the warning information that OBU sends, and RSU determines that this warning information is V2V and/or V2P accuses
Alert business, can determine according to the resource location receiving warning information.
RSU can broadcast, by Cell Broadcast CB or eMBMS mode, the warning information received, in RSU overlay area
Alarm needed for OBU (vehicles or pedestrians) monitors according to existing Cell Broadcast CB or eMBMS operation flow and receives is believed
Breath.
Step S705, OBU sends V2V/V2P warning information.
Wherein, OBU determines according to the instruction information in step S801 and need not report RSU, i.e. instruction information be " announcement
Alarming information reports instruction " it is that false false, OBU select V2V/V2P to send resource according to RSU instruction, and by upper
State resource and send V2V/V2P warning information.
