Embodiment 1

[0104] This embodiment describes a method for determining the relay status of a D2D system, such as figure 2 shown, including:

[0105] Step 10, the relay UE acquires relay configuration information and / or receives device-to-device D2D information;

[0106] The relay UE receives relay configuration information sent by the base station or sent by a ProSe function entity, or the relay UE acquires its own pre-configured relay configuration information;

[0107] The relay configuration information includes at least one of the following contents: relay discovery resource or resource pool information, relay communication resource or resource pool information, activation indication of relay function, indication of deactivation of relay function, relay power saving Enable indication, relay power-saving prohibition indication, relay active state timer, remote UE active state timer. Wherein, the relay discovery resource or resource pool information includes: relay discovery sending r...

Embodiment 2

[0141] This embodiment describes an apparatus for determining a relay state of a D2D system, which is located in a relay user equipment UE, such as image 3 As shown, including information acquisition module and status determination module, where:

[0142] The information acquiring module is configured to acquire relay configuration information and / or receive device-to-device D2D information;

[0143] Specifically, the information obtaining module receives the relay configuration information sent by the base station or sent by the ProSe function, or the information obtaining module obtains the relay configuration information pre-configured by the relay UE;

[0144] The state determination module is configured to determine the relay state of the relay UE according to the relay configuration information and / or D2D information.

[0145] ●Application 1

[0146] The state determination module determines the relay state of the relay UE according to the relay configuration informat...

application example 1

[0181] Officer A and Officer B respectively use UE1 and UE2 with D2D functions. UE1 is in a state with network coverage, while UE2 is in a state without network coverage. This example describes the process for the base station to configure the relay node to enable power saving. UE1 with network coverage is interested in becoming a relay node to provide relay services for UEs without coverage, for example, UE1 is interested in becoming a UE-to-network relay. Such as Figure 5 shown, including the following steps:

[0182] Step 1, UE1 can send D2D relay information to the base station, including an indication of interest in the relay, and the current location information of the UE;

[0183] Step 2, the base station receives the D2D relay information sent by UE1 and selects UE1 as the relay node, then the base station sends relay configuration information to UE1, in this example, UE-to-network relay (UE-to-network relay) configuration establishment information;

Abstract

The invention discloses an equipment direct-through system relay state determination method and device. The method comprises the steps that relay user equipment UE acquires relay configuration information and / or receives device-to-device D2D information, and the relay state of the relay UE is determined according to the relay configuration information and / or the D2D information. The device is arranged in the relay user equipment UE and comprises an information acquisition module and a state determination module. According to the method and the device, the UE with the relay capacity can enter the relay second state without accessing of far-end users and enter the relay first state when receiving the request of the far-end users for searching the relay and periodically broadcast the relay information so that switching of the relay state of the relay UE can be realized through the mode, and the objective of power saving can be achieved when the relay UE is in the relay second state.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a device for determining a relay state of a D2D system. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements on the system capacity and coverage of traditional cellular networks. On the other hand, application scenarios such as public security, social networking, short-distance data sharing, and local advertising have gradually increased people's demand for understanding and communicating with nearby people or things. The traditional base station-centered cellular network has obvious limitations in terms of high data rate and proximity service support. Against this background of demand, D2D (Device-to-Device, device-to- device (or called device pass-through) technology emerged as the times require. The ap...
