Abstract
For supporting selection/authorization of network slicing, a radio access network (RAN) node in a new radio access technology (RAT), e.g. gNB, receives a service request including slice information from a user equipment (UE), and determines a slice based on the slice information. The RAN node forwards the service request including the slice information to a common control plane function (C-CPF), and then, the C-CPF checks whether the UE is authorized for a specific slice. The RAN node receives a service response including an authorization indication for the specific slice from the C-CPF, and performs a corresponding action for the specific slice.
Claims14
A method performed by a radio access network (RAN) node in a wireless communication system, the method comprising:
- receiving a request for a service including slice information from a user equipment (UE);
- selecting a network slice among a plurality of network slices based on the slice information;
- forwarding the request to a common control plane function (C-CPF) related to the selected network slice;
- receiving a response for the service from the C-CPF when the selected network slice is determined by the C-CPF as a final network slice for the service, wherein the response includes authorization information for the selected network slice and a slice identifier (ID) of the selected network slice;
- performing an action related to the service for the selected network slice;
- and
- transmitting the slice ID of the selected network slice to the UE,
- wherein the C-CPF transmits a new session request to a CPF in a core network instance, in response to the selected network slice is determined as the final network, and the C-CPF receives a new session response after a successful session establishment from the CPF.
A radio access network (RAN) node in a wireless communication system, the RAN node comprising:
- a memory;
- and
- a processor, coupled to the memory, that:
- receives a request for a service including slice information from a user equipment (UE),
- selects a network slice among a plurality of network slices based on the slice information,
- forwards the request to a common control plane function (C-CPF) related to the selected network slice;
- receives a response for the service from the C-CPF when the selected network slice is determined by the C-CPF as a final network slice for the service, wherein the response includes authorization information for the selected network slice and a slice identifier (ID) of the selected network slice;
- performs an action related to the service for the selected network slice;
- and
- transmits the slice ID of the selected network slice to the UE,
- wherein the C-CPF transmits a new session request to a CPF in a core network instance, in response to the selected network slice is determined as the final network, and the C-CPF receives a new session response after a successful session establishment from the CPF.
