Title:
MASTER NODE, SECONDARY NODE AND USER EQUIPMENT IN MOBILE COMMUNICATION NETWORK AND COMMUNICATION METHODS THEREBETWEEN
Document Type and Number:
WIPO Patent Application WO/2021/066515
Kind Code:
A1
Abstract:
The present disclosure discloses a master node, a secondary node and a user equipment in a mobile communication network and communication methods thereof. According to an implementation, a method performed by a master node (MN) in a mobile communication network, comprises with receiving from a user equipment (UE), a first message including information reporting a failure of a secondary cell group (SCG) in case that a secondary node change from the source secondary node to a first target secondary node is failed and transmitting, to the source secondary node, a second message including information associated with a failure of the secondary node change, wherein the second message includes at least one of following information, an identifier of the first target secondary node where the failure of the secondary node change occurs, an identifier of the source secondary node to which the UE successfully connects before the failure of the secondary node change, and information on a type of the failure of the secondary node change.
