Proposal to simplify configuration

[thakurajayL]

Description
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 Implementation: 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.

Please clearly tell me

• How configuration simplification is dependent on SMF selection failure
• We need not change the configuration but we can always extend the configuration based on the your need. Like if you need multiple DNN's to be part of device group we can extend functionality but I would not like to change exiting approach which works for many more people.

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.
