Abstract

The present invention provides a communication mode control method, a base station, a user terminal and a system. The communication mode control method includes: after the base station establishes D2D communication between two user terminals in its cell, Monitoring information reported by at least one user terminal among the terminals; the base station determines whether the conditions for maintaining D2D communication between the two user terminals are met based on the monitoring information, and if not, sends a D2D communication mode switch to the at least one user terminal. Notification to cellular network communication mode. This solves the problem in the prior art that when two user terminals performing D2D communication are in a situation that is not suitable for D2D communication, the communication modes of the two user terminals are not switched in time, resulting in poor communication effect of the user terminals. This ensures that the user terminal's communication will not be interrupted, keeping the user terminal's communication smooth and improving the user's experience.

Description

technical field [0001] The present invention relates to the communication field of cellular technology (Cellular), in particular to a communication mode control method, base station, user terminal and system. Background technique [0002] With the development of wireless communication, communication services have higher and higher requirements for delay and spectrum efficiency. Since D2D is a direct communication between devices, the delay can be very low. In addition, , the D2D communication link can be reasonably multiplexed with the spectrum of the cell, further improving the spectrum efficiency. [0003] Since the D2D communication link can be multiplexed with the frequency spectrum of the cell, it may inevitably cause mutual interference between the D2D communication resource and the Cellular communication resource. In the current wireless resource allocation algorithm, it mainly considers how to allocate resources to D2D users (hereinafter referred to as D2D UE) and C...
