Problems solved by technology

[0006] 3. The relay node reconnects with the new anchor node. The new anchor node is not the same node as the anchor node that the relay node was connected to before reestablishing the connection, and the new anchor node cannot obtain the anchor node from other anchor nodes. The context of the relay node
[0008] However, the design of existing technical solutions mainly considers how a UE reconnects with the network, and does not consider the process of reconnecting the relay node, especially how to complete the DU part with the relay node and the UE accessing the DU part reconstruction

Abstract

The present disclosure provides a connection reestablishment method, comprising: receiving a reestablishment message from a second node, the reestablishment message comprising information related to configuration of the second node; performing configuration according to the received reconstruction message; and sending a reconstruction completion message to the second node. The invention also provides a context acquisition method, an interface management method, a UE context management method, a UE context acquisition method, a method for triggering UE to reestablish a connection, and each nodeand a computer readable medium for executing the above method.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and more specifically, to a connection reestablishment method, a context acquisition method, an interface management method, a user equipment (UE) context management method, a UE context acquisition method, and a method for triggering UE connection reestablishment in a wireless communication system , and various nodes and computer-readable media for executing the above method. Background technique [0002] In 5G networks, the research on Integrated Access and Backhaul (IAB) aims to build a multi-hop network architecture to extend the coverage of the network. As an example, such as figure 1 As shown, the network includes an anchor node (IAB donor node) and two relay nodes (IAB node). Some UEs (such as UE1) directly communicate with the anchor node through wireless links, and some UEs communicate with the middle node through wireless links. The relay nodes are connected an...
