    Abstract: The present disclosure provides a method of sending a vehicle-to-everything (V2X) service message. The method includes: determining, by a terminal device, a communication path for a V2X service, where the communication path is selected from at least two communication paths, the at least two communication paths include a first communication path and a second communication path, the first communication path is a communication path on which communication is performed using a PC5 interface, and the second communication path is a communication path on which communication is performed using a Uu interface; and sending, by the terminal device, a message of the V2X service by using the communication path. In the foregoing solution, the communication path can be selected from the at least two communication paths, to send the message of the V2X service. In this way, a communication path is flexibly selected for a V2X service.

    Abstract: Embodiments of the present invention relate to a V2V-based resource allocation method and apparatus. The method includes: receiving a resource request message sent by first user equipment; identifying, according to the resource request message, a level type corresponding to the first user equipment; if the level type is a high priority type, and a quantity of blocks of idle V2V resources in a first resource pool is less than a first preset threshold, or a quantity of required resource blocks that is calculated and a modulation and coding scheme is greater than a quantity of blocks of idle V2V resources in a first resource pool, allocating a V2V resource to the first user equipment. By means of the V2V-based resource allocation method and apparatus, quality of service of user equipment of a high priority type can be ensured.

    Abstract: The method includes: processing a PSNR of each segment of each sample video, determining an ePSNR predictive model according to preset parameters obtained after processing and mean opinion scores of all sample videos, and determining an enhanced mean opinion score eMOS predictive model according to the predictive model. Then, for any video that needs to be evaluated, QoE of the video that needs to be evaluated may be determined according to only the enhanced MOS predictive model and an ePSNR determined according to the ePSNR predictive model. In comparison with a prior-art method for determining QoE in which only a mean value of PERNs of all frames is considered, in this process of measuring quality of experience of a mobile video service, as many as factors that affect a PSNR of a video are considered. Therefore, accurate measurement of quality of experience of an HAS video service can be implemented.
