Problems solved by technology

[0003] However, although the current mainstream solutions in the industry have added consideration of social attributes, they do not take into account the social attributes between user devices. The effectiveness of D2D grouping is poor, which seriously affects the content distribution efficiency of D2D communication

Abstract

The invention discloses a data transmission method and device, a computer storage medium and a system, and is applied to a device-to-device (D2D) communication system, and the method comprises the steps: forming a plurality of D2D groups based on the social credibility, interest similarity and physical constraint conditions between to-be-grouped user equipment and a plurality of D2D user equipment; calculating an average connection probability corresponding to each D2D group, and performing initial resource allocation on each D2D group according to the calculated average connection frequency; and performing data transmission in the D2D group according to the allocated initial resource information. Therefore, since social attributes such as social credibility, interest similarity and physical constraint conditions are comprehensively considered, not only is the accuracy of D2D grouping under high mobility improved, but also the security of data transmission is improved, meanwhile, the spectrum utilization rate is also improved, and the pressure caused by repeatedly downloading redundant contents by the base station can be relieved.

Description

technical field [0001] The present application relates to device-to-device (Device to Device, D2D) communication in the field of communication technology, and in particular to a data transmission method, device, computer storage medium and system. Background technique [0002] In recent years, with the explosive growth of mobile data traffic demand, D2D communication is considered to be the key technology of the next generation mobile communication network, which has extremely obvious gains in enhancing system capacity and spectrum utilization. Among them, within the communication range, user equipment (User Equipment, UE) can complete the transmission and exchange of information through D2D communication; and the packet forwarding technology using D2D communication can improve the overall performance of the cell, but at the same time there are security and effective The problem of poor sex, and the introduction of the concept of social attributes can help to improve these p...
