Single device group for multiple DNNs

[anaswarac-dac]

Currently, the design document for multiple DNNs specifies the use of two separate device groups for the same set of devices. This configuration appears redundant, and I would like to explore whether it is possible to simplify the setup by using a single device group for multiple DNNs.

Details:

Current Design Document: The system uses two device groups for devices with the same characteristics, differentiated only by DNNs.

Question: Is it necessary to duplicate the device group for different DNNs, or can we merge them into a single group ?

Revised Configuration Structure:

Single Device Group: Create one device group that includes the IMSIs.

Multiple DNNs: Within the single device group, define separate DNN-specific configurations such as IP pools, QoS parameters, and DNS settings.

Example Configuration:

device-groups:

• name: "5g-gnbsim-user-group"
  imsis:
  • "001010000000001"
  • "001010000000002"
  • "001010000000003"
  • "001010000000005"
  • "001010000000008"
  • "001010000000009"
    ip-domains:
  • ip-domain-name: "pool1"
    dnn: "internet"
    dns-primary: "10.176.0.11"
    mtu: 1456
    ue-ip-pool: "172.250.0.0/24"
    ue-dnn-qos:
    dnn-mbr-downlink: 200000000
    dnn-mbr-uplink: 20000000
    bitrate-unit: bps
    traffic-class:
    name: "platinum"
    qci: 9
    arp: 6
    pdb: 300
    pelr: 6
  • ip-domain-name: "pool2"
    dnn: "ims"
    dns-primary: "10.176.0.11"
    mtu: 1456
    ue-ip-pool: "172.248.0.0/24"
    ue-dnn-qos:
    dnn-mbr-downlink: 200000000
    dnn-mbr-uplink: 20000000
    bitrate-unit: bps
    traffic-class:
    name: "platinum"
    qci: 9
    arp: 6
    pdb: 300
    pelr: 6
    site-info: "enterprise"

network-slices:

• name: "default"
  slice-id:
  sd: "000000"
  sst: 1
  site-device-group:
  • "5g-gnbsim-user-group"
    application-filtering-rules:
  • rule-name: "ALLOW-ALL"
    priority: 250
    action: "permit"
    endpoint: "0.0.0.0/0"
    site-info:
    gNodeBs:
    • name: "gnb1"
      tac: 1
    • name: "gnb2"
      tac: 2
      plmn:
      mcc: "001"
      mnc: "01"
      site-name: "enterprise"
      upf:
      upf-name: "upf-1"
      upf-port: 8805
      upf-name: "upf.omec-upf-1"
      upf-port: 8805

Explanation:

device-groups: Contains a single entry, 5g-gnbsim-user-group, which includes all the IMSIs.

ip-domains: Lists different DNNs (e.g., internet, ims) within the same device group.

network-slices: Assigns this device group to network slices as needed.
