PoC B/OSS Solution for B2B 5G Network Slicing

As the rollout of 5G continues to gain momentum, there are plenty of avenues for telecommunications providers to exploit. For a European CSP, supporting the increasing needs of B2B companies is one of the main priorities. For this, it’s necessary to upgrade the Business Support Solution (BSS) and Operations Support Solution (OSS). However, before adopting any solution, the CSP wants a proof of concept (POC) for the B&OSS solution based on 5G network slicing. 

This is to ascertain that it will enable them to support new B2B business models and operations over 5G. 

Some of the key objectives for the PoC Include:

  • Transitioning towards a digital-first and cloud-native solution
  • Leveraging network slicing to launch and support new products
  • To assess its integration and interoperability capabilities
  • To assess the capacity and ease of use of the solution
  • Minimize use of legacy systems and maximize operational independence

In this white paper, you’ll find more insight into the CSP’s efforts to secure a reliable B&OSS solution.

Use Cases

The proof of concept will focus on two key use cases:

  • Video Surveillance and Telecontrol
  • Mobile Private Network

Video Surveillance and Telecontrol

As on-premise security becomes a greater concern, video surveillance solutions are becoming a basic security requirement. As businesses continue to adopt these solutions, telcos need to be sure that they can adequately cater to such needs.

As such, in relation to video surveillance and telecontrol, the focus for the POC will be the kind of offer the provider will have for customers. In addition to using a 5G network slicing as the base of communication, this offer will also include: 

  • User equipment such as cameras
  • Storage for the stream
  • Service platform (NVR)
  • Managed services
  • Analytics

To ensure 360-degree service for the customer, the composition of the solution will have a wide range of features that enhance delivery and effectiveness. 

To begin with, there will be seven different camera models, and each will offer varying characteristics. Moreover, each camera will have five different storage options. When it comes to optional services, there will be six available for each camera,

Another key area of focus is pricing and contracts. To cater to different customer needs, there will be different types of contracts. The variations will come in the form of the contract period and prices. Also, depending on camera quantities, B2B customers will also benefit from step discounts. 

Mobile Private Network

The objective of the mobile private network use case is to offer customers a completely private network dedicated to them. As the name suggests, the network will have mobile components. Customers will also access additional network functions as the mobile private network will link with the public Core. 

This solution will come with several elements:

  • A Starter Kit- The starter kit contains the basic equipment necessary to set up a mobile private network.
  • Equipment- With this, customers will get several different components. These include a Core, two terminals, four different radio equipment, and two sim cards.
  • Services- Among the supporting services on offer will include a PTT service, video surveillance (with platform link), and three IoT services (with platform link).
  • Contracts, pricing, and discounts- The contract commitment periods and prices will vary. Customers can choose a one-shot approach, or monthly solutions and discounts will be available based on volume.

Achievements

Upon completion, the proof of concept was largely successful, with achievements realized for both use cases.

Achievements for BSS 

1. Support for the Main B2B Processes

For B2B companies, their needs from telcos are growing. If they’re not adequately met, there may be a need to switch providers. In regard to this proof of concept, it was clear that the solution supports the key B2B process. With this, the CSP can help enhance the performance of clients, which will translate to growth.

Some of the B2B processes it supports include:

  • Lead management & Funnel- For B2B companies, the process of acquiring, cultivating, and converting leads is essential as the client pool is generally not as big as with other sectors. Fortunately, the B&OSS solution supports B2B management. This then serves as a better platform to identify more qualified leads and increase conversion rates.
  • CPQ
  • Contracting
  • Ordering
  • Inventory management
  • Service order orchestration
  • Product lifecycle management

2. Self-service portal- 

One element that significantly reduces the ability of B2B companies to fully capitalize on solutions is the need for support at every stage. With the B&OSS solution also comes a self-service portal for clients. It offers them greater independence and flexibility to manage their accounts, change services, place orders, etc.

3. Differentiation 

With the solution, it is possible to differentiate elements such as CPQ, contracting, and order processing by product or market segment. This makes it easy to identify areas of high performance and those lagging behind, allowing companies to take the necessary remedial measures.

4. Dynamic Pricing 

Instead of offering a standard pricing method that may not be suitable for some clients, the B&OSS solution offers dynamic pricing capabilities. For example, it’s now possible to offer contract pricing, per rules pricing, attribute-based pricing, table-based pricing, and quantity discounts.

Along with these, there are also BSS achievements such as:

  • Flexible templates and electronic delivery that support the generation and sending of proposals
  • Discretionary sales channel and order size discounts with approval flows
  • Flexible catalog definition
  • Standards-based integration

Achievements for the OSS Layer (Symphonica)

As a telecommunications provider, there is no room for inefficient operational systems and processes. When it comes to the operations support system side, achievements come in five primary categories as follows:

1. Multi-Domain Orchestration for Automated Provisioning of Services and Slices

As network providers transition into 5G, multi-domain orchestration and automation of service provisioning will be a primary feature. In this regard, the CSP realized the following benefits from the PoC:

  • NSMF, NSSMF, and E2E Network-Slice lifecycle management
  • Increased capacity for service order decomposition for multiple technical orders
  • Rules-based approach for selecting the best fit
  • NSSMF profile management
  • End-to-end fulfillment spanning from service orders are received to command execution on the necessary network elements 

2. Service and Resource Catalog

With the solution, the CSP was able to gain:

  • Flexible Catalog modeling with two use cases integrated end-to-end from scratch within a few weeks 
  • Workflows powered by catalogs with CFS/RFS/RES reuse for various use cases

3. Design Studio for Catalog, Workflows, and Integrations

Another key element that supports operations is the design studio that offers:

  • Southbound integrations designer with graphical point & click workflow
  • Reusable vendor-agnostic services across services
  • Lower project development costs and reduced time to market due to the no-code designer
  • ONAP Core Simulator Deployment

4. Cloud-Native and Certified Solution

With the cloud-native and certified solution, the CSP can enjoy:

  • Deployments in cloud-based environments are much easier
  • Supports monitoring of business and technical KPIs

5. TM Forum Entities and Open APIs

As a result of the alignment with TM Forum Open APIs and entities, integration with BSS is smooth.

Lessons from the B&OSS Proof of Concept 

From the expectations the CSP had going into the PoC and the outcomes, there were several insightful observations.

  • One of the desires of the CSP was to simplify the integration of work and alignment of CFSS characteristic naming through the TM Forum Open API. To achieve such alignment and avoid changes with each service introduction, the alignment must be catalog/table-driven. During the PoC, they were able to achieve all this.
  • Careful determination must be made on which service attributes are exposed to the customer for presentation, configuration, and/or filtering. This should be accompanied by determining how they map to and influence the OSS view of the RFS, CFSS, etc.
  • In order to deliver the PoC as per the initial schedule, defining the use cases and scope of execution, as well as the CPS’s excellent predisposition to participate in the workshops and answering questions, were key.
  • For the end-to-end testing, the Slack group with Kloudville & Readiness IT was effective.

Although there are areas that need improvement and will do so over time, the B&OSS solution has proven to be effective. With it, the CSPs can adequately cater to the needs of B2B companies.
