Slicing of network resources for dual connectivity using NR

Abstract:

Exemplary embodiments include methods and/or procedures performed by a first network node (1460) in a radio access network, RAN, the first network node (1460) being in communication with a second network node (1460b) configured with a different radio access technology, RAT, than the first network node (1460). Such exemplary embodiments include determining (1210) one or more radio resource management (RRM) identifiers associated with at least one of the following: a user equipment, UE, served by the first network node; a subscriber associated with the UE; and a group of UEs served by the first network node. Exemplary embodiments also include esending (1220) a request for the second network node to establish dual connectivity, as a secondary node, SN, with the UE, wherein the request comprises information relating to the one or more RRM identifiers. Some embodiments can include managing (1230) the UE's access to resources provided by the RAN based on one or more policies associated with the one or more RRM identifiers, while the information relating to the one or more RRM identifiers can map to one or more further policies for managing UE access to resources provided by a RAN including the second network node.
