Embodiment approach 1

[0256] In this embodiment of the present invention, the network device takes a V2X functional entity as an example, such as Figure 9 As shown, the figure includes: , base station, MME, HSS and V2X service functional entities.

[0257] Take the message identifier in the QoS information as the message type as an example, such as Figure 9 As shown, the method provided by the embodiment of the present invention may include the following steps.

[0258] S11, the terminal sends a QoS request message to the V2X service function entity through the base station, where the QoS request message may be a Subscription message.

[0259] S12a, the V2X service function entity searches locally for the QoS information of the terminal. Or, S12b, the V2X service function entity generates a first request message; S12c, the V2X service function entity sends the first request message to the HSS; S12d, the HSS sends the QoS information of the terminal to the V2X service function entity.

Abstract

The present invention proposes a V2X message communication method and device, the method comprising: a terminal sends a QoS request message to a network device; the terminal receives the QoS of the terminal sent by the network device according to the identification information of the terminal Information; the terminal obtains the QoS parameter corresponding to the message identifier of the V2X message to be sent according to the QoS information; the terminal obtains the wireless resource for sending the V2X message to be sent according to the obtained QoS parameter ; The terminal sends the to-be-sent V2X message through the obtained wireless resource. Since the QoS information of each terminal's V2X message can be obtained from the network device, when the terminal sends a V2X message to be sent in the V2X service, it can find the matching QoS information, which meets the requirements of the terminal when implementing the V2X service. communication quality requirements.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a V2X message communication method and device. Background technique [0002] With the rapid deployment of LTE (Long Term Evolution, Long Term Evolution) networks around the world, it provides a network foundation for more and more low-latency, high-data-rate, and wide-coverage services. A typical service is "Internet of Vehicles". Each vehicle in the Internet of Vehicles can be a UE in the LTE network. The Internet of Vehicles can provide a safer driving experience and a richer Internet experience by interconnecting cars. [0003] 3GPP (The 3 rd Generation Partnership Project) is currently researching V2X (Vehicle to Everything, Internet of Vehicles) services based on LTE networks. V2X services include V2V (Vehicle to Vehicle, Vehicle to Vehicle), V2I (Vehicle to Infrastructure, Vehicle to Infrastructure) facilities), V2N (Vehicle to Network, vehicle-to-network)...
