Abstract

The invention discloses a method, a base station and a system for reselecting a relay system, wherein the base station sends a relay terminal reselection message to a user terminal when the base station determines that the user terminal needs to reselect a relay terminal, and the user terminal is enabled to broadcast a relay request message to adjacent areas; a relay candidate terminal receiving the relay request message sends a relay receiving message to the base station when determining that the relay candidate terminal itself can forward data for the user terminal; the base station select one from the relay candidate terminals sending the relay receiving message as a new relay terminal; and the base station sends a relay connection establishing message to the new relay terminal so as to enable the new relay terminal and the user terminal to establish D2D communication. In addition, the user terminal sends a relay termination request to the base station when determining that the relay service is not needed, direct connection is established between the user terminal and the base station when a relay service termination message is received, and the D2D communication established between the user terminal and the relay terminal is switched off. In this way, the network covering performance is improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, base station and system for reselecting a relay terminal. Background technique [0002] With the rapid development of wireless communication technology, wireless spectrum resources are becoming more and more scarce, but at the same time, users have higher and higher requirements for network speed and network coverage continuity, so how to achieve high speed in limited bandwidth resources And wide coverage becomes very important for operators. 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is discussing a new type of D2D (Device-to-Device, device-to-device) communication technology. Through this technique, such as figure 1 As shown, the mobile terminals with a short distance can communicate directly under the control of the base station, avoiding the forwarding of the base station, thereby improving the system efficiency.
