If it is a multicast service, the broadcast type judgment is performed, specifically:
  • the network side device discriminates the range that the V2V message needs to cover according to the service type, and determines which cells need to be broadcast according to the neighbor cell information.
  • the range that needs to be broadcast can be covered by one base station or a small number of base stations, a single cell broadcast mechanism is performed; if the range of the broadcast is required, multiple bases are required. If the station is covered, a multi-cell broadcast mechanism is performed.
  • the V2V message can be transmitted in several cells through the X2 interface between the base stations.
  • the network side device can also determine the broadcast cell range more accurately.
  • the scheme of the first embodiment described above i.e., the scheme for implementing the propagation mechanism for selecting vehicle communication data by the base station
  • the scheme of the first embodiment described above needs to change the architecture of the eMBMS and the SC-PTM so that the base station supports these functions.
  • the advantage of this is that it can help to shorten the transmission delay of V2V, because it needs to introduce additional forwarding delay through the network side device, and the typical value of this extra delay is at least 20ms.
  • a data transmission method for vehicle communication includes:
  • service data (such as vehicle communication service data) arrives at the base station or the network side device.
  • Step 604 Determine whether the service data is transmitted by using a unicast mode or a broadcast mode.

  • UE User Equipment
  • Step 608 When it is determined that the service data is transmitted by broadcasting, it is determined whether the transmission is performed by a single cell broadcast or a multi-cell broadcast.
  • Step 610 When it is determined that the transmission is performed by using a single cell, the cell that needs to be transmitted is determined according to the distribution range of the communication peer, and then the single cell broadcast is performed.

Abstract

La présente invention concerne un procédé et un dispositif de transmission de données pour des communications véhiculaires, une station de base, et un dispositif sur le côté réseau. Le procédé de transmission de données pour des communications véhiculaires consiste à : recevoir des données de communications véhiculaires envoyées par un terminal émetteur ; déterminer, d'après le nombre de terminaux récepteurs qui reçoivent les données de communications véhiculaires ou d'après des informations d'instruction envoyées par le terminal émetteur, s'il faut utiliser un mode unidiffusion ou un mode Diffusion pour transmettre les données de communications véhiculaires ; s'il est déterminé que les données de communications véhiculaires doivent être transmises en mode unidiffusion, transmettre les données de communications véhiculaires directement à un terminal récepteur selon le mode unidiffusion ; et s'il est déterminé que les données de communications véhiculaires doivent être transmises en mode Diffusion, déterminer une plage dans laquelle les données de communications véhiculaires doivent être diffusées et, d'après cette plage, sélectionner un mode de diffusion mono-cellule ou un mode de diffusion multi-cellule pour transmettre les données de communications véhiculaires. La solution technique de la présente invention implémente un mécanisme de transmission V2V basé sur une interface Uu et permet exécuter des communications V2V extrêmement efficaces tout en économisant des ressources de transmission.
