D2D packet communication method, system and related component

Abstract

The invention provides a D2D packet communication method, which comprises the following steps: judging whether the distance between a first user and a user cluster is smaller than a preset distance and whether the number of the user clusters is smaller than a preset value; if yes, obtaining the communication probability of the first user and other users according to the social distance function, the user association function and the real-time trust degree corresponding to the first user and based on a Chinese restaurant algorithm; obtaining the independent grouping probability of the first user according to the communication probability and the independent grouping expected parameters of the first user; and performing grouping according to the grouping probability and performing intra-group communication. Through the combination of a Chinese restaurant algorithm and social distance parameters, a trust calculation model is introduced to measure the legitimacy of user identities, and real-time credibility measurement is carried out on users participating in D2D grouping, so that personal privacy disclosure is prevented, and invasion of illegal users is resisted. The invention also provides a D2D packet communication system, a computer readable storage medium and communication equipment, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the communication field, in particular to a D2D packet communication method, system and related components. Background technique [0002] In the current communication and Internet fields, the Internet of Everything has become an inevitable trend of technological development. However, the rapid increase in the amount of data brought about by the diversification of people's various needs is out of sync with the development of current communication technologies. In order to enable users to seamlessly and efficiently access the network anytime, anywhere, the 5G system will focus on the development of 4G evolution technologies and emerging technologies. Among them, D2D communication technology and its extended technology V2X have become research hotspots since their appearance. As a key candidate technology for 5G, Device-to-Device communication (Device-to-Device, D2D) has the potential to improve system performance, imp...

Problems solved by technology

[0004] However, the existing D2D communication does not take into account the real-time changes of the user status, which makes the D2D communication process less secure and less efficient. Therefore, how to improve the security of D2D communication is a technical problem urgently needed to be solved by those skilled in the art.
