Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] D2D communication is a technology that allows terminals to communicate directly through the wireless resources of multiplexing cells under the control of the network. In the D2D technology of LTE, user equipment (UE, User Equipment) communicates through the PC5 interface. For ProSe (Proximity based Services) communication, the PC5 interface is different from the Uu interface between the normal UE and the base station. Its connection concept...

Abstract

The embodiment of the present invention discloses a service processing method and device based on D2D relay communication, including: when receiving the backhaul link weakening indication message of the first relay device, maintaining the connection with the first relay device ; After receiving the preset time T of the backhaul link weakening indication message, if the second relay device has been searched, release the connection with the first relay device, and communicate with the searched The second relay device establishes a connection. The technical solution proposed by the embodiment of the present invention enables the remote device to wait for a preset time T before establishing a connection with the second relay device, thereby avoiding the ping-pong effect of the remote device when switching relays.

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, User Equipment) for D2D communication, some of which are located within the coverage area of ​​the cell, and some are located outside the coverage area of ​​the c...
