Problems solved by technology

[0003] The disadvantage of the existing technology is: in the current D2D communication, the off-network UE can only randomly select the relay UE, which makes the selected relay UE not necessarily able to provide the relay function for the off-network UE well

Embodiment 1

[0100] Figure 7 Selecting a relay UE for the network-assisted UE is a schematic diagram of the implementation process of Embodiment 1. In this embodiment, it is described that when the network side finds that the UE may be offline through the measurement report reported by the UE, the UE is notified of the relay function around it. UEs and their current load conditions. As shown in the figure, the implementation may include the following steps:

[0101] Step 701, the relay UE reports to the network side that it has the relay capability.

[0102] Step 702, the UE is in the network state, and the UE sends a measurement report to the base station.

[0103] In a specific implementation, measurement reporting may be periodic or event-triggered.

[0104] Step 703, the network side finds that the UE is about to go off the network.

[0105] In a specific implementation, the base station can judge that the UE may go offline when it finds that the signal quality of the serving cell...

[0112] Figure 8 Schematic diagram of the implementation process of the second embodiment of selecting a relay UE for the network-assisted UE. In this embodiment, when the network side finds that the UE may be offline through the measurement report reported by the UE, the UE is notified of the relay function around it. UEs and the current UU interface quality information of these UEs. As shown in the figure, the implementation may include the following steps:

[0113] Step 801: the relay UE reports to the network side that it has the relay capability.

[0114] Step 802, the UE is in the network state, and the UE sends a measurement report to the base station.

[0115] In a specific implementation, measurement reporting may be periodic or event-triggered.

Embodiment 3

[0124] Figure 9 Schematic diagram of the implementation process of the third embodiment of selecting a relay UE for the network-assisted UE. In this embodiment, when the network side finds that the UE may go offline through the measurement report reported by the UE, select a suitable relay UE for the UE and notify it through the air interface After the UE is disconnected from the network, the UE can maintain communication with the network through the relay UE selected by the network. As shown in the figure, the implementation may include the following steps:

[0125] Step 901: the relay UE reports to the network side that it has the relay capability.

[0126] Step 902, the UE is in the network state, and the UE sends a measurement report to the base station.

[0127] In a specific implementation, measurement reporting may be periodic or event-triggered.

[0128] In step 903, the network side finds that the UE is about to go offline, and the base station selects a suitable ...

Abstract

The invention discloses information processing and determining methods and equipment for relay user equipment. When user equipment has a relay supporting function, the user equipment reports to a network side that the user equipment has a relay supporting function; a base station distributes auxiliary information carrying the user equipment with a relay supporting function to user equipment belonging to the base station to enable the user equipment belonging to the base station to choose relay user equipment after being offline, and / or, the base station indicates the user equipment belonging to the base station to choose relay user equipment after the user equipment is offline according to the auxiliary information of the user equipment with a relay supporting function; and after offline is confirmed, the user equipment chooses relay user equipment according to the information and / or the indication. By adopting the scheme, offline user equipment can choose appropriate relay user equipment, the communication quality of user equipment-network communication is improved, and data transmission of offline user equipment is ensured.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for information processing and determination of relay user equipment. Background technique [0002] In the future development of the mobile communication system, in order to better meet user needs, a D2D discovery (Device to Device Discovery) mechanism and a D2D communication (Device to Device Communication) mechanism are introduced. For an off-network UE (User Equipment, user equipment), in order to allow it to communicate with the network, the off-network UE can select an adjacent on-network UE to relay data for it. This scenario is called UE-to-Network Relay (device relay to the network). [0003] The disadvantage of the prior art is that in the current D2D communication, the off-network UE can only randomly select a relay UE, which makes the selected relay UE not necessarily be able to provide a relay function for the off-network UE well. C...
