Service processing method and service processing device based on D2D (Device-to-Device) relay communication

Abstract

The embodiment of the invention discloses a service processing method and a service processing device based on D2D (Device-to-Device) relay communication. The service processing method comprises the following steps: keeping connection with first relay equipment when return link weakening indication information of the first relay equipment is received; and releasing connection with the first relay equipment if second relay equipment is searched after the return link weakening indication information has been received for a preset time T, and establishing connection with the searched second relay equipment. By means of the technical scheme provided by the embodiment of the invention, remote equipment is only connected with the second relay equipment after waiting for the preset time T, so that ping-pong effects of the remote equipment while relaying is switched are avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service processing method and device based on D2D relay communication. Background technique [0002] In the LTE-A research project proposed by the 3GPP organization, it is necessary to provide new technologies on the basis of LTE to meet the requirements of IMT-Advanced and provide higher data rates and system capacity. Therefore, device-to-device (D2D, Device-to-Device) communication is introduced to improve spectrum utilization. D2D communication improves spectrum utilization by sharing wireless resources with normal cell users under the control of cell base stations. [0003] The 3GPP organization has introduced a partial coverage D2D communication technology, that is, two or more user equipment (UE, UserEquipment) for D2D communication, some are located within the coverage area of ​​the cell, some are located outside the coverage area of ​​the cell, and some ...

AI Technical Summary

Problems solved by technology

The existing technology has realized the connection management of the UE within the coverage of the cell, that is, the relay device can establish a radio resource control (RRC, RadioResourceControl) connection and a non-access stratum (NAS, NonAccessStratum) connection with the base station to perform base station and relay connection management between remote devices and relay devices, currently there is no connection management mechanism between remote devices and relay devices in the prior art
