BUSINESS DRIVERS

This section describes Business Drivers for this Use Case.

Executive Summary -  This Use case is based on a real scenario: Internet Companies like Tencent have the needs to order on-demand 5G service. It inspires us to design this use case. on the one hand, it prvides a new cooperation pattern between Operators and verticals using ONAP; On the other hand, by exploring ONAP capabilities and open ONAP abilities, we set an example of how to use ONAP to provide the end to end slice service orchestration systematically by realizing CSMF, Business exposure system, NSMF within ONAP.

1. Provide End to End Slice Service functions to the 3rd parties like service order, service change, on-demand service activation/deactivation, user-slice allocation policies.
2. Open ONAP capabilities to verticals.
3. Provide customized E2E service monitoring.

Business Impact - 1, This use case will realize a new collaboration pattern between Vertical Industries like Internet companies by opening Service providers capabilities to Verticals by ONAP. 2,  Provide a reference implementation of CSMF and Business Exposure Platform within ONAP. 3, Decouple NSMF and NSSMF, which means ONAP will play the role of NSMF, connecting NSSMF from different domains and different vendors.

Business Markets -  This is a B2B2C scenario, Service Providers provide e2e 5G Service to Vertical Industries and also open ONAP capabilities to Verticals for better service experience. Verticals will provide the end users 5G service on-demand by sending commands to ONAP.

Funding/Financial Impacts -  TBD.

Organization Mgmt, Sales Strategies - (It is suggested that you use the following wording): There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider. (This would typically describe the "WHO", but because use cases are all deployed with ONAP itself, these two areas come with the actual ONAP deployment and uses the organizational management and sales strategies of a particular service provider's ONAP deployment)

User Story

B2B2C Scenario：The internet companies, eg: Tencent, have the need to buy on-demand 5G service：

1. They only want 5G service to be provided in hot spot and some specific time period instead of keeping it alive all the time.
2. They have the demand to divide their App users to different slices according to their VIP level and the slice SLA.
3. They want to monitor and measure the slice performance based on their rules.

High light of this Use Case

1, Provide a prototype(reference implementation) of CSMF in ONAP, the functions of which include order slice service (generate S-NSSAI), NST selection, transferring slice service requirements into network slice requirements.
2, Provide a prototype (reference implementation) of Business Exposure Platform in ONAP. Connect Internet App server with the core network elements like NEF, PCF, to distribute real-time user / slice allocation policy. Besides, open ONAP capabilities to App server.
3, Decouple NSMF and NSSMF, which means ONAP will play the role of NSMF, connecting NSSMF from different domains and different vendors. Functions like slice activation and slice modification will be realized in this case.
4, Open ONAP modules to 3rd party Apps, eg: open DCAE ability to App server to let Verticals define their customized service monitor KPI; open Policy for verticals to trigger the related action like activating slice and modifying slice.
