Embodiment 1

[0078] The above-mentioned user equipment determines the probability of having a V2X communication demand according to the obtained geographical location information of itself, so as to determine whether to perform V2X information detection and the frequency of V2X information detection. The specific steps are as follows:

[0079] Step 1: The user equipment determines its own geographical location through a positioning technology.

[0080] Step 2: The user equipment, according to the obtained geographic location information, determines the probability of having a V2X communication demand.

[0081] Step 3: The user equipment determines whether to detect V2X information and the frequency of V2X information detection according to the probability of V2X communication demand.

[0082] For example: according to the geographical location information obtained in step 1, for example, the user equipment is located indoors, such as a handheld terminal, then in step 2 it is judged that th...

Embodiment 2

[0086] The user equipment determines the detection frequency of the V2X information according to the distance between itself and other user equipment, and the steps are as follows:

[0087] Step 1: The user equipment obtains its own geographic location information.

[0088] Step 2: The user equipment detects the V2X information and obtains the geographic location information of other vehicles.

[0089] Step 3: The user equipment calculates the distance between the user equipment and one or more other user equipments according to the geographic location information obtained in steps 1 and 2.

[0090] Step 4: The user equipment judges the number of other user equipments within a certain threshold distance d, and further determines the V2X information detection frequency.

[0091] For example, if there are other user equipments within a certain threshold distance d, a high detection frequency is adopted for V2X information, for example, on the receiving resource pool, V2X inform...

Embodiment 3

[0093] The user equipment determines the V2X information based on its own motion trajectory and / or geographic location information and / or speed information, as well as the motion trajectory and / or geographic location information and / or speed information of other user equipment obtained by detecting V2X information. The detection frequency, the specific steps are as follows:

[0094] Step 1: The user equipment obtains its own motion trajectory and / or geographic location information and / or speed information according to the positioning technology and / or the detection of the sensing device.

[0095] Step 2: The user equipment obtains the motion track and / or geographic location information and / or speed information of other user equipment by receiving the V2X information.

[0096] Wherein, the motion trajectories of other user equipments are obtained directly from the V2X information by detecting the V2X information. Or, by receiving the V2X information of other user equipments, t...

Abstract

The present invention provides a V2X communication method and a device. The method comprises the steps of acquiring the user attribute information; according to the user attribute information, determining detection parameters used for detecting the first V2X information, and detecting the first V2X information according to the detection parameters; and / or, determining sending parameters for sending the second V2X information according to the user attribute information, and sending the second V2X information according to the sending parameters. Based on the method and the device, the problem in the prior art that the phenomena of resource congestion and limited energy easily occur during the current V2X communication process can be solved. The V2X communication reliability is improved. Meanwhile, the problem of congestion control is solved and the purpose of saving energy is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a V2X communication method and device. Background technique [0002] In recent years, with the rapid development of the world economy and China's economy, vehicles have become a very popular means of transportation in many countries in the world, including China. Moreover, the penetration rate of vehicles will continue to increase. While vehicles bring convenience to people's lives, they also inevitably have some negative impacts on humans, such as traffic accidents, urban congestion, and environmental impacts. From the perspective of traffic accidents, taking China as an example, there were 204,196 traffic accidents nationwide in 2012, with 59,997 deaths, 224,327 injuries, and direct property losses of 1.175 billion yuan. [0003] With the rise of Internet of Vehicles technology, the above problems can be solved to a certain extent. The Internet of Vehicles refers to a larg...
