Example Embodiment

[0068] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0069] In order to solve the problem that two UEs cannot communicate directly through the PC5 interface, 3GPP has proposed a UE-to-UE Relay communication system architecture. Based on this architecture, when two UEs cannot directly communicate through the PC5 interface, the above two UEs can relay the service data of the two through t...

Abstract

The embodiment of the invention provides a link configuration method and device. The first UE determines a first configuration parameter of a first relay link between the first UE and the Relay UE, configures a first relay link according to the first configuration parameter, and sends the first configuration parameter to the Relay UE, so that the Relay UE configures a second relay link between theRelay UE and second UE by using the first configuration parameter. The first relay link and the second relay link are configured by adopting the first configuration parameter, so that the configuration of the first relay link and the configuration of the second relay link are the same. Through the technical scheme provided by the invention, when two pieces of UE cannot perform direct connection communication through a PC5 interface, the relay links are respectively configured between the two pieces of UE and the Relay UE, so that the two pieces of UE relay service data through the Relay UE torealize direct communication.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a link configuration method and device. Background technique [0002] In Release 12 (Release 12, Rel-12), Long Term Evolution (Long Term Evolution, LTE) introduces Proximity-based Services (Proximity-based Services, ProSe) direct communication (Device-to-Device, D2D). Multiple user equipments (User Equipment, UEs) can directly communicate through the PC5 interface. The PC5 interface is a direct interface between UEs. [0003] The service and system aspects (work group, WG) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) introduced UE-to-UE relay when studying the system architecture of ProSe direct communication (UE-to-UE Relay) communication architecture. This architecture enables two UEs that cannot directly communicate through the PC5 interface to implement direct communication by relaying service data...
