1. A method performed by a Radio Access Network, RAN, node for RAN action when redundancy is not available, the method comprising:
receiving, from a core network node, a request for a set of User Plane, UP, resources in a RAN;
determining whether the request for the set of UP resources in the RAN can be met; and
sending, to the core network node, a response to the request for the set of UP resources that is based on whether the request for the set of UP resources in the RAN can be met.
