1. A method performed by a first network node configured to operate in a radio access network (RAN), the method comprising:
determining a radio access technology (RAT)/Frequency Selection Priority (RFSP) index associated with a user equipment (UE) served by the first network node;
managing the UE's access to resources of the RAN based on one or more radio resource management (RRM) policies associated with the RFSP index; and
sending, to a second network node, a request for the second network node to establish dual connectivity with the UE as a secondary node (SN), wherein:
the request includes the RFSP index, and
the RFSP index is also associated with one or more further RRM policies, at the second network node, for managing the UE's access to resources of a RAN that includes the second network node.
