In sum, provide a kind of communication system architecture in embodiments of the present invention, set including terminal Standby, base station, access point set, and home server functional entity etc., wherein terminal passes through base station or access Point set is set up and is connected between local service functional entity, can pass through D2D direct link between terminal unit It is in communication with each other, and data relay services can be provided for other-end.Specifically provide at least following scheme：
Source sends terminal and is eating dishes without rice or wine to pass through independent transmission plan respectively by D2D Link, carries out source respectively Send the temporary mark transmission of terminal, and business data transmission.
Link terminal can only forward to temporary mark, or, D2D Link loading condition can be regarded Temporary mark and business datum are all forwarded.
Receiving terminal sends, according to source, the local service functional entity mark part carrying in the temporary mark of terminal Divide and determine target local service functional entity, receiving terminal just can be made using the temporary mark that source sends terminal For index, initiate query script by sending the home server functional entity of terminal to source, the source that obtains sends The business datum of terminal.
Local service center is verified to terminal identity in terminal registration process, and interim to terminal distribution Mark, and set up context for terminal.Local service center preserves and sends, from source, the business datum that terminal obtains. Local service center triggering base station or access point, by multicast and broadcast mode in cellular downlink transmission sources Send temporary mark information and the service data information of terminal.And local service functional entity is whole according to receiving The positional information at end determines the mode of multicast and broadcast target area.
The service related data part that source sends in terminal-pair business datum carries out content rechecking function, and Transmission on D2D Link for the business datum part can be stopped in the case of repeating finding business tine part.

Local Cloud Server functional entity according to the terminal unit having communication function report with regard to itself, or Communication capacity that what it was adjacent have or the no geographical position of the object of communication capacity and movement state information, generate Generate local traffic map in real time.
Home server functional entity is according to the geographical position of terminal, and adjacent area parameter setting, for spy Determine terminal and generate real-time traffic cartographic information, and be adjacent in this terminal relative between object or terminal unit After position changes, the real-time traffic cartographic information after updating is notified this terminal.
From such scheme, in existing car networking truck traffic, " application data " of vehicle is eating dishes without rice or wine to lead to Cross broadcast mode to be transmitted, therefore reliability is relatively low；In addition it is to expand truck traffic distance, car networking car Car communication employs the mode that " application data " is carried out with multi-hop directly forwards, and not only reliability is low, and Multi-hop transmission of eating dishes without rice or wine is likely to result in D2D Link congestion in the case that vehicle is intensive.Source is sent out in this application Make arrangements for his funeral end can only one jump scope be send business datum, so both ensure that to delay requirement high business Can be properly received with extremely short time delay, D2D Link load under multiple jump condition will not be caused simultaneously again Overweight problem.Scope beyond jumping for one, on the one hand permits in the case of D2D Link light load Permitted business datum is forwarded on D2D Link, simultaneously for ensureing reliability in the range of multi-hop, sent Business datum is sent and is preserved to cell edge server function entity by end, and therefore one jumps the outer terminal of scope As long as detecting terminal existence information it is possible to the temporary mark information of terminal is sent as index according to source, Obtain corresponding service data information from cell edge server function entity, thus substantially increasing multi-hop feelings Communication reliability under condition, reduces D2D Link load.
In addition traditional car networking is to ensure effectively to cover, the effective range of single-hop typically 300 about, and this In application, the effective range of single-hop can be reduced to several meters to tens meters, not only can substantially reduce terminal transmission Power is thus reach energy-conservation purpose, and the terminal unit that unit area in can carry can be greatly improved and hold Amount, meet city terminal unit extremely intensive in the case of communication requirement.
In existing car networking, no matter whether " application data " content changes, and vehicle termination all will eated dishes without rice or wine " application data " is carried out periodically send, if the terminal topology of vehicle node periphery is relatively-stationary In the case of, " application data " repeats transmission and the waste of resource and source on D2D Link can be caused to send terminal energy The waste of amount aspect.Using the application, the situation if the business datum part in business datum does not change Under, terminal node can stop at and periodically send the business datum repeating on D2D Link (in business In the case that data is constant, source sends terminal and only can periodically send temporary mark information, for nearby eventually The existence that end equipment sends terminal to source confirms), thus negative on the D2D Link substantially reducing Carry.
In addition, unmanned for realizing 5G, vehicle Terminal Type equipment is except needing by receiving discovery signal Mode surrounding is had communication function equipment found outside in addition it is also necessary to enter to the object of no communication function Row finds (such as barrier, wild animal etc.), is therefore equipped with High Accuracy Radar, the first-class biography of high-definition camera The vehicle Terminal Type equipment of sensor function, is finding no to lead to by itself radar or the first-class sensor device of shooting After the object of telecommunication function, can by the geographical position of the no communication function being measured by Radar Technology object, And movement state information process after generate figure grid or the map vector of such as radar imagery, and pass through Image the attribute (such as pedestrian, animal etc.) to barrier for the first-class sensor, or directly will capture in real time Image information (such as traffic indication board, real-time surrounding image) be sent to by cellular communication mode Local Cloud Server functional entity.The nothing in geographic area that local Cloud Server functional entity manages to it is led to The position of the object of telecommunication function and movement state information are preserved in real time, and will by broadcast or mode of unicast No the position of the object of communication function and movement state information notify near have the equipment of communication function (for example Vehicle, bicycle, pedestrian's wearable device) etc..The information type that concrete terminal needs report (includes car The information that sensor directly collects (such as real time video image crawl), or vehicle is to vehicle-mounted biography Business datum (such as map vector) or event message (example that the data that sensor collects generates after being processed As collision alarm message), the biography that local cloud control function can according to actual needs with the installation of vehicle Sensor and in-vehicle processor disposal ability do specific configuration).
In a word, the application can be according to the loading condition in business information content and D2D Link, dynamic tune Load on whole D2D Link, thus be prevented effectively from asked due to the transmission delay that congestion on D2D Link leads to Topic and transmission reliability problem, thus the sound assurance communication reliability of following intelligent transportation system.This Outward because the application supports the discovery to no communication capacity object and the terminal unit having communication capacity simultaneously, real When push traffic map information, therefore can be applicable to the unmanned scene of 5G vehicle.
