Slicing of network resources for dual connectivity using NR

A method performed by a second network node configured to operate in a radio access network (RAN), the method comprising:

• receiving, from a first 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 a radio access technology (RAT)/Frequency Selection Priority (RFSP) index associated with the UE, wherein the RFSP index is also associated with one or more further RRM policies, at the first network node, for managing the UE's access to resources of a RAN that includes the first network node;
• mapping the RFSP index to one or more further radio resource management (RRM) policies for a RAT that the second network node is configured with;
• and
• managing the UE's access to resources of the RAN based on the one or more further RRM policies.

A first network node configured to operate in a radio access network (RAN), the first network node comprising:

• communication interface circuitry configured to communicate with at least a second network node;
• and
• processing circuitry operably coupled to the communication circuitry, whereby the processing circuitry and the communication interface circuitry are configured to:
• determine a radio access technology (RAT)/Frequency Selection Priority (RFSP) index associated with a user equipment (UE) served by the first network node;
• manage 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
• send, to the 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.
