    1. each S-NSSAI may contain a Subscribed DNN

      Subscription for one S-NSSAI: 1. a list of Subscribed DNN 1. one default DNN

    2. PDU Session types are defined: IPv4, IPv6, IPv4v6, Ethernet, Unstructured.
    3. The expectation is that the URSP in the UE is always up to date

      Use URSP to sync DNN to UE.

    1. Network Slice Simultaneous Registration Group (NSSRG)

      restrictions to the simultaneous registration of network slices

    2. For any S-NSSAI, the network may at any one time serve the UE with only one Network Slice instance associated with this S-NSSAI until cases occur

      For the same S-NSSAI, network only have unique network slice instance serving for the UE.

    3. a Network Slice instance can be associated with one or more S-NSSAIs, and an S-NSSAI can be associated with one or more Network Slice instances

      S-NSSAI and Network Slice instance doesn't have a one-to-one relationship.

    4. eight S-NSSAIs

      Max 8 S-NSSAIs in Allowed and Requested NSSAI.

    5. such S-NSSAI is comprised of either both an SST and an SD or only an SST without a standardised SST value and no SD

      non-standard values,

    6. Network Slice Simultaneous Registration Group (NSSRG)
    7. Network Slice Admission Control (NSAC)
    8. Network Slice-Specific Authentication and Authorization (NSSAA)
    9. Number of simultaneous connection of Network Slice instances per UE is limited

      up to 8?

    10. The AMF instance serving the UE logically belongs to each of the Network Slice instances serving the UE,

      The AMF serving for the UE will also serve for all slices of the UE.

    1. UE Configuration Update procedure for transparent UE Policy delivery

      PCF tiggered

    2. NSSAI information (e.g. Allowed NSSAI),

      need acknowledgement

    3. trigger UE to perform
      1. Mobility Registration Update procedure while the UE is in CM-CONNECTED state
      2. Mobility Registration Update procedure while the UE is in CM-IDLE state
    4. Access Type (i.e. 3GPP access or non-3GPP access)

      Access Type : {3GPP, non-3GPP}

    5. UE Configuration Update

      UE Configuration Update -> UCU

    1. When UE is in CM-Idle

      When the UE has registered but still in CM-IDLE

    2. Registration Request

      When the UE is first powered on.

    3. Registration Request and Service Request

      Note: "and"

    4. once an RRC connection has been established


    5. CM-Connected

      has signaling connection

    6. CM-Idle

      No signaling connection

    7. N1 logical interface and it is combination of following

      N1 logical interface UE <==RRC ==>gNB<==N2-AP==>AMF

    8. Connection Management (CM) is used to establish and release the control plane signaling connection between UE and AMF.

      connection = connection between UE and AMF

    9. 5G System Connection Management

      CM -> Connection Management

    1. Basically APN is controlling network parameters (or configurations) by switching the traffic to various different gateway on the core network.
