Abstract
Methods and Radio Access Network (RAN) nodes for improved RAN redundancy. A method at a first RAN node for enabling redundancy with multiple active instances comprises: triggering multiple instances for the first RAN node to be active simultaneously, such that a processing load at the first RAN node can be distributed among the multiple instances and a part of the processing load handled by an instance of the multiple instances can be taken over by at least one other instance of the multiple instances when the instance fails.

A method at a first Radio Access Network (RAN) node for enabling redundancy with multiple active instances, the method comprising:
- triggering multiple instances for the first RAN node to be active simultaneously, such that a processing load at the first RAN node can be distributed among the multiple instances and a part of the processing load handled by an instance of the multiple instances can be taken over by at least one other instance of the multiple instances when the instance fails.

A method at a second RAN node for facilitating a first RAN node in enabling redundancy with multiple active instances, the method comprising:
- communicating with at least one of multiple instances for the first RAN node that are active simultaneously, to enable the first RAN node to distribute its processing load among the multiple instances and a part of the processing load handled by an instance of the multiple instances can be taken over by at least one other instance of the multiple instances when the instance fails.

The method of claim 34, wherein when the first RAN node is a gNB-CU-CP and the second RAN node is a gNB-CU-UP, the second message is a GNB-CU-CP CONFIGURATION UPDATE message having a “TNLA Usage” IE with a value of “both” for the network address associated with the second instance,
- wherein when the first RAN node is a gNB-CU-CP and the second RAN node is a gNB-DU, the second message is a GNB-CU CONFIGURATION UPDATE message having a “TNLA Usage” IE with a value of “both” for the network address associated with the second instance.
