Patent ID: 10813018

Abstract:
The invention refers to a transfer of a User Equipment context from a source secondary network node (110A) to a target secondary network node (110B) that is different than the source secondary network node, wherein the UE (105) is served by a master network node (120) and the source secondary network node (110A), the source secondary network node (110A): transmitting a first message to the target secondary network node (110B), the first message comprising a handover request, receiving a second message comprising configuration data of the target secondary network, and after receiving the second message, transmitting to the master network node a third message comprising the configuration data of the target secondary network node; the invention further referring to a master network node (120): receiving a first message from the source secondary network node, the first message comprising a request to initiate a transfer of the UE context from the source secondary network node to the target secondary network node, in response to the request, transmitting a second message to the target secondary network node, and receiving a third message from the target secondary network node, the third message comprising configuration data of the target secondary network node.
