Patent number: 11963243Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.Type: GrantFiled: April 7, 2021Date of Patent: April 16, 2024Assignee: QUALCOMM IncorporatedInventors: Karl Georg Hampel, Naeem Akl, Navid Abedini, Jianghong Luo, Luca Blessent, Junyi Li
