Moreover, to support the use cases demanded by digital customers, such a platform must also be aligned with and support network standards that include 3GPP, TMF, CAMARA, TIP and more, and have the flexibility to expand beyond standard APIs so that they can uniquely customize the required capabilities. Network-as-a-platform (NaaP) was created to address the stringent needs to provide low latency, accurate device monitoring, optimum functions app placement, strong privacy and security, all while conforming with cloud-native and disaggregation principles. Furthermore, with its future-proofed service infrastructure, applications’ cloud-native character and ability to consume basic network services via abstract APIs and data models, it is able to support B2B and B2B2X collaboration. NaaP is built on three design principles. The first is the need for a unified service model and catalog that can serve as a single source of truth across the business, IT, and network layers. The second is the ability to abstract network APIs from serviceproduct APIs to enable independent development, testing and integration in both IT and network domains, as well as with partners. Importantly, these must be able to occur in parallel, as well as in a decoupled manner, to allow for service velocity and scale. At the same time, it must conform as closely as possible with open standards to minimize silo creation and technical debt accrual. The third principle is having highly configurable data model-driven decomposition and orchestration , which enables the NaaP and isolation layer to not only support B2B and B2C communication services, but also services that support B2C, B2B and B2B2X. To comply, network service providers must do the following in a safe and agile manner: Open their network menu Expose APIs to consumers, businesses and partners in an application developer-friendly manner Create a service creation ecosystem for developers Expose new network and IT capabilities White PaperAmdocs Network Service Exposure Platform 4 White Paper Amdocs Network Service Exposure Platform This whitepaper addresses factors for boosting network service velocity, strategies for extracting maximum value from a traditional network- or service-centric strategy, and as a result delivering enhanced NaaP capabilities. As customers demand new, differentiated 5G services, and as CSPs strive to achieve vertical specialization and extended businessoperational footprints through hyperscaler and metaverse ecosystems, the pressure on CSPs has never been greater. To achieve these objectives, these players are constantly on the search for agile business operating models and partnerships. Yet such models and partnerships must be able to provide solutions to support a network whose complexity far surpasses that of 4G: with more layers, more network functions, as well as a shift to software and cloud-native principles and tools, while being programable and self-configurable.

The benefits of this “as a platform” concept range from scalability and lightweight operational capability management, all the way to reduced integration costs. The ability to leverage such benefits becomes particularly crucial in any environment where the diversity and scale of tech demands are constantly growing and evolving. Examples include the need 5 White Paper Amdocs Network Service Exposure Platform to adjust network behavior in real time, support drone networks for equipment maintenance (e.g., in farming and engineering use cases) and AR VR applications. Inevitably, such complexity will only grow with the next wave of consumer and enterprise services on the horizon, with autonomous vehicles, electric flying vehicles (eVTOL) and smart cities, all of which will require high bandwidth, carrier-grade reliability, and cost efficiencies. Support too will need to be found for evolving customer expectations. While previously, services on-demand would suffice, demand is now growing for online services, coupled with new connectivity options (including 5G), as well as support for highly accurate visibility and monitoring. To ensure full lifecycle management for such solutions, enterprise partners will need to build their own services and make them available within the network operator ecosystems. For a glimpse into this future reality, we need look no further than verticals, such as retail and entertainment, that have already adopted this approach with the following outcomes: New services created to meet new demands in days rather than months Easy, rapid creation and integration of new services that can be charged for in simple and in novel ways Ability for app providers to leverage network capabilities: − Extract information from network − Control networking, applications, services, and functions on demand New business models that support offer bundling, including: − Leveraging the network, cloud-native functions, and vertical applications − Shuffled as a platform − Available on demand − Ability to support industry-specific use cases − Made available through API exposure Yet to realize these benefits, these players first had to evolve their service infrastructure to become more cloud native-driven, flexible, self-optimized and specialized. On the flipside, such capabilities came at the cost of introducing multi-dimensional complexities resulting from the diversity of network suppliers, function and testingvalidation, and evolution requirements. In addition to the above, CSPs in pursuing similar goals, will also face industry-specific 5G challenges such as massive traffic volumes and growing numbers of connected devices. In their favor, standards bodies from TMF, ETSI, O-RAN Alliance, TIP and Linux Foundation (CAMARA project) are already addressing this problem with prescribed open interfaces and reference implementations. Based on our long-standing involvement in these bodies, as well as our established leadership in BSS and OSS, Amdocs is frequently approached by the operator community for our experience and expertise in bridging the gaps between IT and network. 6 White PaperAmdocs Network Service Exposure Platform Amdocs Network Service Exposure Platform (NSEP) Network Service Exposure Platform (NSEP) Amdocs’ vision uses software engineering techniques to build a networ...

operator community for our experience look no further than verticals, such as retail and and expertise in bridging the gaps between IT and entertainment, that have already adopted this network approach with the following outcomes: • New services created to meet new demands in days rather than months • Easy, rapid creation and integration of new services that can be charged for in simple and in novel ways • Ability for app providers to leverage network capabilities: − Extract information from network − Control networking, applications, services, and functions on demand • New business models that support offer bundling, including: − Leveraging the network, cloud-native functions, and vertical applications − Shuffled as a platform − Available on demand − Ability to support industry-specific use cases − Made available through API exposure 5 Amdocs Network Service Exposure Platform White Paper Amdocs Network Service Exposure Platform (NSEP) Amdocs’ vision uses software engineering techniques to build a network abstraction and exposure layer that modularizes and decouples the network from IT This ensures ordering issues remain with IT, while network teams provide the “how” of creating a service Meanwhile, partner capabilities can be used to compose or enrich network service capabilities, which can be subsequently exposed alongside other network APIs to formalize customer end-to-end solutions As part of the network abstraction layer, we provide the following key capabilities: • Service catalog to define network services, validation rules and API parameters Network Service Exposure Platform (NSEP) 6 Amdocs Network Service Exposure Platform White Paper • API management of the integration layer, Use case example: providing access to network capabilities via a network service edge and lifecycle variety of APIs management • Network services & edge orchestration for highly 5G services, such as network slicing and mobile configurable, data model-driven

following is an example for 5G service chargeable events to update billing monetization • Security for access & usage policies • Network catalog and network orchestration • Operational portals for CSP NetOps and − Onboard network functions and network partners applications are required for end-to-end service creation Taking this approach a step further, our broad view of service lifecycle management addresses − Define and design new services with all service the requirements of network, service and IT, as elements, including 5G slice definition well as the delivery of data and control via pre- programmed service behaviors (also known as − Define service lifecycle management “intents”) This ensures relevant requests are routed operational and orchestration policies to relevant functions via closed-loop automation, based on the scope of each request So for − Deploy service definition across network example, while a request to change session quality ecosystem would be sent
