Embodiment 1

[0116] Figure 8 It is a flowchart of a method for forwarding V2X services by an eNB using SC-PTM according to an optional embodiment of the present invention, as shown in Figure 8 As shown, the steps of the method include:

[0117] In step S802, the OBU receives user service description USD information.

[0118] Wherein, the OBU receives the USD information sent by the server through the application layer, and the USD information includes at least: the V2X service identifier. The V2X service identifier is indicated by TMGI.

[0119] Step S804, the OBU sends an indication message to the eNB;

[0120] Wherein, the indication message at least includes: a V2X service identifier or a V2X service identifier index.

[0121] The OBU sends the V2X service identifier through RRC signaling or L1 / 2 layer signaling. For example, the OBU sends the V2X service identifier through the random access process or the RRC connection establishment process; the V2X service identifier is TMGI or...

Embodiment 2

[0138] Figure 9 It is a flowchart of a method for eNB forwarding V2X services through PWS according to an embodiment of the present invention, as shown in Figure 9 As shown, the steps of the method include:

[0139] In step S902, the OBU sends the V2X service to the eNB.

[0140] Wherein, the V2X service includes V2X service indication information, that is, the eNB can determine that the received data is V2X service data through the indication information.

[0141] In step S904, the eNB determines to use the PWS to send the V2X service.

[0142] Among them, the eNB uses the PWS to send the V2X service through comprehensive judgment based on the attributes of the V2X service, such as size, delay requirements, and priority. PWS refers to system broadcast messages sent through SIB10-12.

[0143] In step S906, the eNB sends a paging message.

[0144] Wherein, the base station eNB sends a paging message, in which the SIB10-12 is indicated to be updated.

[0145] In step S90...

Embodiment 3

[0150] It should be noted that this optional embodiment is that the base station forwards the V2V service through MBSFN, which is similar to the process of the first embodiment, the main difference is: 1) the eNB uses the MBSFN subframe to send the V2X service, 2) the eNB configures the MCH scheduling information MSI to indicate the V2X Business scheduling. 3) The OBU detects and receives the V2X service on the required MBSFN subframe.

Abstract

The invention provides an IOV (Internet of Vehicles) V2X business forwarding method and device, and the method comprises the steps that a base station eNB receives the information which comprises the V2X business identification or a V2X business identification index and is transmitted by an OBU (on-board unit) through a Uu port; the eNB determines a to-be-transmitted V2X business according to the V2X business identification or the V2X business identification index, and determines a forwarding mode of the V2X business; the eNB carries out the forwarding of the V2X business transmitted by the OBU in a forwarding mode through the Uu port. According to the invention, the method solves a problem that the OBU and the eNB are difficult to carry out the forwarding of the V2X business through the Uu port in the related technologies.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for forwarding V2X services of the Internet of Vehicles. Background technique [0002] Vehicle to Everything (V2X for short): refers to the provision of vehicle information through sensors, on-board terminals and electronic tags loaded on the vehicle, and the realization of vehicle-to-vehicle (V2V for short) by using various communication technologies. Vehicle to Pedestrian (V2P for short) and Vehicle to Infrastructure (V2I for short) are interconnected, and information is extracted and shared on the information network platform to effectively control vehicles and provide comprehensive services. figure 1 It is a schematic diagram of sending traffic and scheduling information to vehicles through a network information platform in the related art. [0003] The Road Side Unit (RSU for short) can receive vehicle requests to ensure that the vehicle is connected ...
