Vehicle network V2X service sending method and apparatus
Provided is a method for sending a V2X service. The method includes: a Vehicle-to-Everything (V2X) Application Server (AS) classifies and identifies the V2X service, where different types of V2X service have different identifiers; the V2X AS sends a request message to a Broadcast Multicast Service Center (BM-SC), where the request message is used for instructing the BM-SC to establish a Multimedia Broadcast Multicast Service (MBMS) bearing corresponding to an identifier of the V2X service; and the V2X AS sends the V2X service through the MBMS bearing established by the BM-SC.
1. A method for sending a V2X service, comprising:
classifying, by a Vehicle to Everything (V2X) Application Server (AS), the V2X service according to a type of the V2X service, and identifying, by the V2X AS, the classified V2X service, wherein different types of V2X services include different identifiers, the different types of V2X services comprises a periodic type of V2X services and an event-triggered type of V2X services;
sending, by the V2X AS, a request message to a Broadcast Multicast Service Center (BM-SC), wherein the request message is used for instructing the BM-SC to establish a Multimedia Broadcast Multicast Service (MBMS) bearing corresponding to an identifier of the V2X service; and
sending, by the V2X AS, the V2X service through the MBMS bearing established by the BM-SC,
wherein sending, by the V2X AS, the V2X service through the MBMS bearing established by the BM-SC comprises:
sending, by the V2X AS, announcement information of the V2X service to an On-Board Unit (OBU), wherein the announcement information comprises a starting time for sending the V2X service and a carrier frequency on which the V2X service is sent; and
sending, by the V2X AS, the V2X service through the MBMS bearing to the target area of the V2X service determined by the V2X AS; and
wherein the method is performed by at least one processor.
2. The method according to claim 1 , wherein the MBMS bearing comprises at least one of: Single Cell Point-to-Multipoint (SC-PTM), or Multimedia broadcast Single Frequency Network (MBSFN).
3. The method according to claim 1 , wherein the identifier of the classified V2X service includes a Temporary Mobile Group Identity (TMGI) allocated by the BM-SC.
4. The method according to claim 1 , wherein the request message carries at least one of: Quality of Service (QoS) of the V2X service, a broadcast area for indicating a target area of the V2X service, or a starting time for sending the V2X service.
5. A non-transitory computer readable storage medium storing computer-executable instructions for executing the method of claim 1 .
6. An apparatus for sending a V2X service, comprising:
a processor; and
a memory for storing instructions executable by the processor,
wherein the processor is configured to perform a method for sending the V2X service, the method comprising:
classifying, by a Vehicle to Everything (V2X) Application Server (AS), the V2X service according to a type of the V2X service, and identifying, by the V2X AS, the classified V2X service, wherein different types of V2X services include different identifiers, the different types of V2X services comprises a periodic type of V2X services and an event-triggered type of V2X services;
sending, by the V2X AS, a request message to a Broadcast Multicast Service Center (BM-SC), wherein the request message is used for instructing the BM-SC to establish a Multimedia Broadcast Multicast Service (MBMS) bearing corresponding to an identifier of the V2X service; and
sending, by the V2X AS, the V2X service through the MBMS bearing established by the BM-SC,
wherein sending, by the V2X AS, the V2X service through the MBMS bearing established by the BM-SC comprises:
sending, by the V2X AS, announcement information of the V2X service to an On-Board Unit (OBU), wherein the announcement information comprises a starting time for sending the V2X service and a carrier frequency on which the V2X service is sent; and
sending, by the V2X AS, the V2X service through the MBMS bearing to the target area of the V2X service determined by the V2X AS.
7. The apparatus according to claim 6 , wherein the MBMS bearing comprises at least one of: Single Cell Point-to-Multipoint (SC-PTM), or Multimedia broadcast Single Frequency Network (MBSFN).
8. The apparatus according to claim 6 , wherein the identifier of the classified V2X service includes a Temporary Mobile Group Identity (TMGI) allocated by the BM-SC.
9. The apparatus according to claim 6 , wherein the request message carries at least one of: Quality of Service (QoS) of the V2X service, a broadcast area for indicating a target area of the V2X service, or a starting time for sending the V2X service.
