Abstract

The invention provides an access control method and an access control system for a D2D communication link. The access control method comprises the steps of: judging a service type of data transmission of the current D2D communication link; establishing a mathematical model of connecting time of data transmission of the D2D communication link according to social information of the current D2D communication link when the service type of data transmission is a time sensitive type; calculating an access success rate of the current D2D communication link according to the mathematical model of connecting time; and comparing the access success rate of the current D2D communication link with a preset target success probability, and adding the current D2D communication link into an admission set conforming to access control if the access success rate of the current D2D communication link is greater than or equal to the preset target success probability. The access success rate of the D2D communication link is obtained by adopting the access control method, the service quality requirement of the D2D communication link is guaranteed, and the selection rate of the D2D communication link is increased.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an access control method and system for a D2D communication link. Background technique [0002] In recent years, with the emergence of smart mobile terminals, modern life has undergone tremendous changes, and today's life increasingly relies on ubiquitous high-speed, high-quality wireless networks. However, the resulting explosive growth of wireless traffic is limited by existing network capacity and network bandwidth. In the prior art, the device-to-device (D2D for short) technology is introduced into the cellular mobile communication system, which can make the system take advantage of the short-distance characteristics of the D2D communication link and the wide distribution of user equipment (User Equipment, UE for short). Advantageous conditions, effectively save spectrum resources, achieve resource space division multiplexing gain, adapt to local data sh...
