Embodiment 1

[0102] Figure 8 is a flow chart of the AS requesting the BM-SC to allocate a TMGI method according to an optional embodiment of the present invention, such as Figure 8 As shown, the steps of the method include:

[0103] In step S802, the OBU sends the V2X service to the V2X AS.

[0104] Among them, the OBU sends the V2X service to the V2X AS through unicast bearer.

[0105] In step S804, the AS requests the BM-SC to allocate a TMGI.

[0106] Among them, the AS requests TMGI from the BM-SC according to the received V2X service type. Different V2X service types correspond to different TMGIs, or the AS finds that the valid time of the originally obtained TMGI is about to expire, and sends a request to the AS to extend the valid time of the TMGI. .

[0107] In step S806, the BM-SC allocates the TMGI and notifies the AS.

[0108] Among them, the BM-SC allocates the TMGI and the corresponding valid time, and notifies the AS.

[0109] In step S808, the AS sends a request to a...

Embodiment 2

[0123] Figure 9 is a flowchart of a method for automatically assigning a TMGI by a BM-SC according to an optional embodiment of the present invention, such as Figure 9 As shown, the steps of the method include:

[0124] In step S902, the OBU sends the V2X service to the V2X AS.

[0125] In step S904, the V2X AS sends an MBMS bearer activation request message to the BM-SC.

[0126] In step S906, the BM-SC establishes an MBMS bearer.

[0127] In step S908, the BM-SC sends a response message to the AS.

[0128] Wherein, the response message includes at least one of the following: TMGI, flow ID, valid time, service description, BM-SCIP address and port.

[0129] In step S910, the AS sends a V2X service notification.

[0130] In step S912, the AS sends the V2X service through the BM-SC.

[0131] Step S914, the RSU broadcasts the V2X service in the target area.

[0132] In step S916, the OBU detects and receives the required V2X service. The process ends.

Embodiment 3

[0134] Figure 10 is a flowchart of a method for sending V2X services in MBSFN mode according to an optional embodiment of the present invention, as shown in Figure 10 As shown, the steps of the method include:

[0135] In step S1002, the OBU sends the V2X service to the V2X AS.

[0136] In step S1004, the V2X AS sends an MBMS bearer activation request message to the BM-SC.

[0137] In step S1006, the BM-SC establishes an MBMS bearer.

[0138] In step S1008, the BM-SC sends a response message to the AS.

[0139] In step S1010, the AS sends a V2X service notification.

[0140] In step S1012, the AS sends the V2X service through the BM-SC.

[0141] In step S1014, the MCE determines to send the V2X service in the MBSFN manner.

[0142] Wherein, the MCE determines to adopt the MBSFN mode according to at least one of the following conditions: the service area in the MBMS session start message, the operator's policy, and the indication information of the AS or BM-SC.

Abstract

The present invention provides a method and device for sending V2X services of the Internet of Vehicles, wherein the method includes: a V2X AS of the Internet of Vehicles application server classifies and identifies the V2X services of the Internet of Vehicles, wherein different types of V2X services have different identifications; V2X The AS sends a request message to the broadcast multicast service center BM‑SC, where the request message is used to instruct the BM‑SC to establish a multimedia broadcast multicast service MBMS bearer corresponding to the V2X service identifier; the V2X AS sends the message through the MBMS bearer established by the BM‑SC V2X business. The present invention solves the problem in the related art that the vehicle networking application server V2X AS is difficult to forward different types of V2X services.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending V2X services in the Internet of Vehicles. Background technique [0002] With the rapid economic and social development, China's car ownership has grown rapidly, and road traffic accidents have occurred frequently, which has become one of the important factors affecting the public's sense of security in recent years. Road traffic safety has become a basic issue affecting social harmony and improving people's livelihood one. China urgently needs to improve traffic safety in terms of technology, policy, education and other aspects, and improving vehicle safety design is an important part of it. [0003] Technologies to improve vehicle safety are mainly divided into passive safety technologies and active safety technologies. Passive safety technology is used to protect people and objects inside and outside the vehicle after an accident; active safe...
