Abstract
The invention provides an information broadcast multi-cast method and device for automatic drive, a management entity and a base station. The method comprises the steps that the Internet-of-Vehicles broadcast multi-cast service management entity in the base station receives first information sent when an emergency of an automatic drive vehicle-mounted terminal in the base station covering range occurs, wherein the first information carries security related information of the emergency; the Internet-of-Vehicles broadcast multi-cast service management entity sends the first information to all automatic drive vehicle-mounted terminals in the base station covering range. According to the method, by locally and additionally arranging the Internet-of-Vehicles broadcast multi-cast service management entity on the base station, the base station can directly forwarding the security related information sent by the automatic drive vehicle-mounted terminal without forwarding the security related information to a core network server and then sending down the security related information through an eBM-SC, the data pack forwarding procedure is simplified, and the time delay is shortened.
Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of information towards automatic Pilot is more
Broadcast broadcasting method, device, management entity and base station.
Background technology
The diffusion of very important security related information in automatic Pilot technology needs to use broadcast
Multicasting technology, once there is vehicle collision or accident early warning, this kind of security message is needed with most fast
Speed spreads in particular range, and usual delay requirement is in Millisecond；Support the height of automatic Pilot
Precision 3D map segment dynamic increment is updated the data can also be sent to using broadcast multi-broadcasting technology
Car networking terminal in particular range.
Long Term Evolution (Long Term Evolution, abbreviation LTE) system adopts broadcast multi-broadcasting
Technology (Evolved Multimedia Broadcast Multicast Service, abbreviation eMBMS),
Multiple users can be given by identical content distribution, greatly save the frequency spectrum resource of preciousness, it is theoretical
On for access number of users do not limit, will not be due to the increase of number of users, to business
Experience produces impact.Fig. 1 is the logical architecture of eMBMS, multiple cell/multicast coordination entity
(multi-cell/multicast coordination entity, abbreviation MCE) as logic entity,
Multiple cell transmission is being carried out (i.e. using multicast/multicast single-frequency network network (Multimedia Broadcast
Multicast service Single Frequency Network, abbreviation MBSFN) transmission means)
When, for being managed collectively to the Radio Resource of all base station eNBs in eMBSFN regions,
Including distribution time-domain resource and configuration, specifically wireless parameter (is such as modulated and coding strategy
(Modulation and Coding Scheme, abbreviation MCS) etc.), to ensure multiple cells
Between eMBMS transmission synchronization.In deployment, MCE can be as some functional entitys (such as
ENB a part), or an independent entity.EMBMS gateway (eMBMS
Gateway, abbreviation eMBMS GW) major function be to send/broadcast eMBMS data point
Group to each carrying eMBMS eNB, and with mobile management entity (Mobility
Management Entity, abbreviation MME) complete the interaction of eMBMS session control signalings.Extensively
Broadcast Multicast-Service Center (broadcast multicast service center, abbreviation eBM-SC) to carry
For eMBMS business operations, session transmissions, security control, content synchronization, distribution multicast mesh
The function such as IP address.
