S5-212390 LS to TM Forum on introduction of 3GPP Autonomous Network Levels
Body 
1       Overall description

3GPP SA5 is now working on Autonomous Network Levels, the study output is
captured in TR 28.810 (the latest version is TR 28.810 V17.0.0), and the
normative work is ongoing, the output will be captured in TS 28.100 (the latest
version is draft TS 28.100 V0.3.0).

3GPP SA5 would like to inform of the following achievements that has been
agreed by SA5 and specified in draft TS 28.100 V0.3.0. And 3GPP SA5 would like
to coordinate with TM Forum for the following 3 aspects to have common
understanding.

- Concepts

        - Autonomous network concept : the ultimate goal for autonomous network
        is to enable telecommunication system to be governed by itself with
        minimal to no human intervention. See clause 4.1 of the attached draft
        TS 28.100 V0.3.0 for details.

        - Autonomous network level concept : the term Autonomous network level
        is used to describe the levels of autonomy capabilities in the
        autonomous network to improve the efficiency for network management and
        control. See clause 4.2 of the attached draft TS 28.100 V0.3.0 for
        details.

- Dimensions for evaluating autonomous network levels

        - Scenarios : including network and service deployment, network and
        service maintenance, network and service optimization. See clause 4.3.2
        of the attached draft TS 28.100 V0.3.0 for details.

        - Management scope : including NE/NF layer, domain network layer, cross
        domain network layer and communication service layer. See clause 4.3.3
        of the attached draft TS 28.100 V0.3.0 for details.

        - Workflow : including intent handling, awareness, analysis, decision
        and execution. See clause 4.3.4 of the attached draft TS 28.100 V0.3.0
        for details.

- Framework approach for evaluating autonomous network levels : see clause 5 of
the attached draft TS 28.100 V0.3.0.

3GPP SA5 would like to inform TM Forum about the above 3 aspects and  get your
feedback

2       Actions

To TM Forum Autonomous Networks team

Action 1:

3GPP SA5 kindly asks TM Forum to take the above information into account and
provide feedback about the 3 following aspects if needed.

- Concepts : specified in clause 4.1 and 4.2 of the attached draft TS 28.100
V0.3.0.

- Dimensions for evaluating autonomous network levels : specified in clause 4.3
of the attached draft TS 28.100 V0.3.0.

- Framework approach for evaluating autonomous network levels : specified in
clause 5 of the attached draft TS 28.100 V0.3.0.

Action 2:

Please keep SA5 informed of the progress of TM Forum’s work on autonomous
network levels.
