Network slicing allows operators to create networks that are tailored to provide solutions optimized for a variety of market scenarios that require different requirements in the areas of functionality, performance and isolation.
- the network slice is implemented through a network slice instance (NSI).
- NSI is a collection of network function instances and necessary resources (eg, computing, storage and networking resources) that form a deployed network slice.
- the NSI may be isolated logically and / or physically completely or partially from other NSIs.
- Resources include physical and logical resources.
- NSIs can be configured as subnetwork instances, and can be shared by multiple NSIs in special cases.

- the RAN may have a C-Plane interface directly with a specific C-Plane function located within the CNI.
- the C-Plane function depicted as part of the C-CPF is considered to be a C-Plane function within the CNI, so there is no C-CPF.
- CNI consists of a single C-Plane feature set and a single U-Plane feature set.
- CNI is dedicated for UEs belonging to the same UE type. Identification of the UE type is performed using specific parameters, for example, UE Usage Type and / or subscriber information of the UE.
- the C-Plane feature set is responsible for authorizing the UE to the network, for example by performing UE mobility support or authentication and subscription verification if required.
- the U-Plane function set in the CNI provides a specific service to the UE and transmits U-Plane data of the specific service. For example, one U-Plane feature set in CNI # 1 provides eMBB services to the UE while another U-Plane feature set in CNI # 2 provides crisis communication services to the UE.

- the RAN communicates with the C-CPF through a single C-Plane interface regardless of which C-Plane functions within the C-CPF. Therefore, C-CPF is regarded as a black box.
- CCPSF The common C-Plane selection function (CCPSF) is considered part of the C-CPF, ie it is assumed that the CCPSF is located within the C-CPF.
- CCPSF is responsible for determining the C-CPF with which the base station should communicate. The determination of the C-CPF is performed by examining the subscription profile of the UE.
- CCPSF is not a function to route NAS signaling messages to the correct C-CPF. This solution assumes that the RAN has the ability to route NAS signaling messages to the appropriate C-CPF by taking information sent by the CCPSF in the case of an initial connection request or by the UE in the case of all subsequent messages.
- UE Usage Type is used to identify the type of UE, for example a car UE usage type, a smartphone UE usage type, and the like.
- DCN-ID is used to identify a specific dedicated core network for each UE usage type.
- operators may consider using a DCN-ID to identify a particular dedicated core network for different variants of an enterprise or dedicated core network of the same UE usage type.
- One example of the latter case may be to have different variations of a dedicated core network for CIoT UEs that support different cellular internet-of-things (CIoT) optimization features.
- the DCN-ID is used to determine the C-CPF specific to this UE usage type and (optionally) to a particular UE enterprise of this UE usage type. For example, you might think that you could deploy a core network in different automotive companies that belong to the same type of UE.
- Service Type is used to identify the type of service the CNI is expected to support. For example, an automotive UE may want to connect to multiple CNIs that simultaneously support eMBB services and vehicle-to-everything (V2X) services.
- V2X vehicle-to-everything
- DNN is used to identify the PDN with which the UE wishes to communicate for a particular service type.
- DNN # 1 is an Internet service that requires mobile broadband service.
- Temporary UE ID is a temporary ID provided to the UE by the core network. This is similar to the globally unique temporary identifier (GUTI) in the evolved packet system (EPS) case. This temporary UE ID consists of two parts: 1) ID of C-CPF, and 2) UE specific ID.
- GUI globally unique temporary identifier
- EPS evolved packet system

- PLMN public land mobile network
- the RAN uses this DCN-ID to determine the appropriate C-CPF to support this DCN-ID, and the signaling flow It continues in step S103 mentioned later.
- the UE may also provide other information such as service type and / or DNN with this network connection request.
- the RAN uses the temporary UE ID to determine the dedicated C-CPF, and the signaling flow continues at step S103 described later.
- the UE may also provide other information such as DCN-ID, service type and / or DNN with this network connection request.
- the UE When the UE sends a request to connect to the operator's network, the UE may request to establish a session for a particular service by sending a DNN with this network connection request.
- the dedicated C-CPF will establish a session for the requested service similarly to steps S111, S112, and step S113 described later in FIG.
- step S101 the CCPSF located in the basic C-CPF determines which C-CPF should be connected in consideration of information (eg, DCN-ID) in the received network connection request from the UE in step S100.
- information eg, DCN-ID
- Other information from the subscription database may also be considered.
- the subscription of the UE may indicate that the operator should establish a session with the subscribed CNI.
- this CNI is CNI # 1.
- the base C-CPF determines that it will provide this UE's network connection request, the base C-CPF continues authentication and allows the UE to connect / connect to the operator's network. Or, the basic C-CPF rejects this UE's network connection request, so this procedure ends at this step. This particular case is not shown in FIG. 3 to simplify the signaling flow.
- step S102 the basic C-CPF sends a response to the RAN node with the C-CPF to which the UE will connect.
- the same contents of the network connection request of the UE in step S100 are also returned to the RAN.
- the RAN uses only temporary UE IDs to route NAS messages to the appropriate C-CPF.
- step S103 if there is a pool of C-CPs dedicated to this DCN-ID provided by this UE usage type and / or by the UE or by the basic C-CPF in step S102, the RAN node may use the NAS node selection function (NNSF). ; Execute the NAS node selection function.
- NSF NAS node selection function
- the RAN node routes the network connection request of the UE to the dedicated C-CPF.
- This request may include other information, such as a DNN, to allow a dedicated C-CPF to select a particular CNI for a particular service type.
- step S105 authentication and authorization is performed to connect / connect the UE to the operator's network.
- a key is also provided for decrypting NAS messages between the UE and the dedicated C-CPF.
- the dedicated C-CPF sends a network connection accept response to the UE.
- This response may include the temporary UE ID and the information to be configured for the UE, for example which DCN-ID, the corresponding service type and / or the corresponding DNN that the UE is allowed to connect to. If the newly provided DCN-ID does not match the DCN-ID that the UE already has, the DCN-ID will be configured at the UE.
- FIG. 4 is a second part of the signaling flow to support connection with multiple CNIs.
- the signaling flow of FIG. 4 follows the signaling flow of FIG. 3.
- 4 illustrates an SM procedure for supporting connection with multiple CNIs.
- step S110 the UE requests establishment of a session for a communication service (eg, service # 1 provided by CNI # 1) by sending an SM request for a new PDU session.
- a communication service eg, service # 1 provided by CNI # 1
- the UE provides a DCN-ID and a DNN.
- step S111 the RAN forwards the PDU session request to the appropriate dedicated C-CPF using the DCN-ID information sent by the UE.
- the dedicated C-CPF selects the dedicated CPF of CNI # 1 using the DNN information of the PDU session request, and the CNI # that is responsible for session management in CNI # 1 for the PDU session request of the UE for service # 1. 1 to CPF-1 (ie, CNI-1 CPF-1).
- This forwarded PDU session request still contains the information sent by the UE, such as UE usage type, DCN-ID and DNN.
- step S113 after successful session establishment, CPF-1 of CNI # 1 sends the session response back to the dedicated C-CPF.
- step S114 the dedicated C-CPF sends a new service response back to the UE via the RAN.
- step S120 the UE requests to establish another session for a new communication service that is a service type different from the previous service.
- the UE provides a temporary UE ID, UE usage type, DCN-ID, service type and / or DNN.
- step S121 the RAN determines the dedicated C-CPF using the temporary UE ID sent by the UE and forwards the PDU session request to the dedicated C-CPF.

- Deliver to CPF-1 ie, CNI-2 CPF-1).
- This forwarded PDU session request still contains the information sent by the UE, such as the UE usage type, DCN-ID, service type and / or DNN.
