example 1

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

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

[0135] The vehicle-mounted terminal obtains configuration from a V2X application server or a V2X function entity (V2X function) or a proximity service entity (Prose function) through a pre-configuration method or a 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] The user plane bearer means that the V2X terminal accesses the V2X application server or V2X function entity (V2X function) or proximity service entity (Prose function) through LTE or other networks and obtains resource information from the server.

[0138] Resource informat...

example 2

[0143] This embodiment shows how the terminal receives V2X messages from other operators when the eMBMS receiving mode is adopted in scenario 2. Picture 11 It is a schematic diagram of the process according to Example 2 and Example 3 of the present invention, such as Picture 11 As shown, including the following steps:

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

[0145] The base station side uses 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 information, and ...

example 3

[0152] This embodiment shows how the terminal receives V2X messages from other operators when the SC-PTM receiving mode is adopted in scenario 2, such as Picture 11 As shown, including the following steps:

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

[0154] The base station side uses SC-PTM (Single Cell Point-to-Multipoint System) 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 (carrier list), MBMS service area (SAI) (MBMS SAI), adjacent cell list in the carrier frequency list, V2X service identification information (TMGI) supported in the adjacent cell list , The corresponding specific reso...

Abstract

The invention provides a method, a device and a system for transmitting a vehicle-to-everything communications (V2X) message. The method comprises the following steps that: network side equipment acquires V2X resource information and/or V2X resource configuration information, wherein the V2X resource information is used for transmitting a V2X message of a non-service operator, and the V2X resource configuration information is used for acquiring the V2X resource information by a terminal; and the network side equipment transmits the V2X resource information and/or the V2X resource configuration information to the terminal. Through adoption of the method and the system supporting transmission of a V2V service in a multi-operator multi-carrier-frequency scene, the problem that the V2V service cannot support the multi-operator multi-carrier-frequency scene in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a method, device and system for transmitting V2X messages in vehicle networking communication. Background technique [0002] With the rapid economic and social development, the number of cars in China has grown rapidly, and the frequent occurrence of road traffic accidents has become one of the important factors affecting our public sense of safety 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, etc., of which improving vehicle safety design is an important part of it. [0003] The technology to improve vehicle safety is mainly divided into passive safety technology and active safety technology. Passive safety technology is used to protect people and objects inside and outside the vehicle after an accident; act...
