Problems solved by technology

[0005] In D2D communication, when two terminals are far apart or in other situations that may lead to unstable D2D communication, the communication quality may be very unsatisfactory. At this time, the existing technology usually switches to base station communication, and frequent communication link switching is not only It may increase communication energy consumption and even affect the user's content distribution experience, so not all situations are suitable for content distribution through D2D communication

Abstract

The invention relates to the technical field of communication, and discloses a content distribution method based on D2D reliability. The method comprises the following steps: acquiring distances amonga plurality of D2D communication terminals according to a preset interval time; obtaining a reliability prediction value between any two D2D communication terminals according to the distance; determining a content distribution coverage degree according to the reliability prediction value; and performing content distribution according to the content distribution coverage. According to the method,by predicting the reliability of the communication mode of the D2D communication terminals in advance, the obtained content distribution coverage can consider stable communication between the D2D communication terminals, and frequent switching of communication links during content distribution is effectively avoided. The invention further discloses a content distribution device based on the D2D reliability.

Description

technical field [0001] The present application relates to the field of communication technology, for example, to a method and device for content distribution based on D2D reliability. Background technique [0002] With the continuous development of mobile communication technology and the popularization of various communication devices, the number of mobile users is also increasing rapidly. In recent years, a large number of smart terminal devices have been increasing day by day, and emerging communication services that meet user-specific needs are also on the verge of explosion. The contradictions between the explosive growth of data traffic carried by mobile communications and the shortage of wireless spectrum resources are emerging. How to effectively increase network capacity It has become an urgent task to improve the utilization rate of wireless spectrum and improve the end user experience in different communication modes. [0003] The D2D (Device-to-Device, direct-to-...
