example 1

[0133] In this embodiment, in Scenario 1, the V2X terminal obtains the V2X resource information configured by the network and receives / sends the V2X information of other operator networks, including the following steps:

[0134] Step S31, the network side provides the V2X resource information of the non-service operator for the V2X terminal;

[0135] The vehicle-mounted terminal obtains configuration from a V2X application server, a V2X function entity (V2X function) or a proximity service entity (Prose function) through pre-configuration or user plane bearer.

[0136] The pre-configuration method is the V2X resource configuration information configured in the machine when the device leaves the factory.

[0137] User plane bearer means that a V2X terminal accesses a V2X application server, a V2X function entity (V2X function) or a proximate service entity (Prose function) through LTE or other networks and obtains resource information from the server.

[0138] Resource informa...

example 2

[0143] This embodiment describes how the terminal receives V2X messages from other operators when the eMBMS reception mode is adopted in scenario 2, Figure 11 It is a schematic flow chart according to Example 2 and Example 3 of the present invention, such as Figure 11 shown, including the following steps:

[0144] Step S41, the network side provides the V2X resource information of the non-service operator of the V2X terminal;

[0145] The base station side adopts eMBMS (Enhanced Multimedia Broadcast Multicast System) for downlink transmission.

[0146] The base station obtains the V2X resource information of other operators through the X2 interface or the S1 interface or the network management (O&M) method. The resource information indicates V2X resource information of different operators. The information includes one or a combination of the following information: adjacent carrier list (carrier list), MBMS service area (SAI) (MBMS SAI), V2X service identification informat...

example 3

[0152] This embodiment describes how the terminal receives V2X messages from other operators when the SC-PTM reception method is adopted in Scenario 2, such as Figure 11 shown, including the following steps:

[0153] Step S41, the network side provides the V2X resource information of the non-service operator of the V2X terminal;

[0154] The base station side adopts SC-PTM (single cell point-to-multipoint system) mode for downlink transmission.

[0155] The base station obtains the V2X resource information of other operators through the X2 interface or the S1 interface or the network management (O&M) method. The resource information indicates V2X resource information of different operators. The information includes one or a combination of the following information: adjacent carrier list (carrierlist), MBMS service area (SAI) (MBMS SAI), adjacent cell list in the carrier list, V2X service identification information (TMGI) supported in the adjacent cell list, Specific resour...

Abstract

The present invention provides a method, device, and system for transmitting V2X messages of the Internet of Vehicles communication, wherein the method includes: a network side device acquires V2X resource information and / or V2X resource configuration information of the Internet of Vehicles communication, wherein the V2X resource information Used to transmit V2X messages of non-serving operators, the V2X resource configuration information is used by the terminal to obtain the V2X resource information; the network side device sends the V2X resource information and / or V2X resource configuration information to the terminal . The present invention provides a transmission method and system for supporting V2V services in multi-operator and multi-carrier frequency scenarios, and solves the technical problem that V2V services cannot support multi-operator and multi-carrier frequency scenarios.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for transmitting V2X messages of Internet of Vehicles communication. 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 a...
