Abstract

The present invention relates to the field of communication technology, in particular to a method for discovering a terminal based on user attributes, including: using a 3VSL model to establish a trust relationship between users, finding a set of trusted users corresponding to the requesting user; , use the multi-order Marko model to predict the user's movement trajectory, and get the predicted location information of the trusted user at a certain moment in the future; request the user to set an appropriate beacon detection rate according to the predicted location information of the trusted user at a certain moment in the future; the user is constantly moving During the change process, the beacon detection rate is adjusted according to the distance between the requesting user and the trusted user. The invention can save energy consumption, reduce the scope of equipment discovery, and significantly improve the equipment discovery rate.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for discovering terminals based on user attributes. Background technique [0002] In order to solve the contradiction between the rapidly increasing demand for data traffic and the increasingly tight spectrum resources, D2D communication technology was proposed and received extensive attention. [0003] In D2D communication, D2D users transmit data by sharing the spectrum of cellular users, which effectively improves the utilization of spectrum resources. At the same time, this technology allows two devices to communicate directly without going through the base station, thereby reducing the network traffic burden carried by the base station, and is considered one of the key technologies of 5G. In addition, the device can provide local connectivity even when the network infrastructure is damaged. [0004] It is a prerequisite for establishing a D2D communication ...
