1st review
SaT5G - Satellite And Terrestrial network for 5G
We evaluated many use-cases for greatest potential for market impact and revenues, and these four came out on top (WP2.1, D2.1):
1. Edge delivery and offload of content and VNF software,
2. 5G fixed backhaul, for connecting cellular base-stations,
3. 5G to premises, in parallel with fixed network to enhance broadband,
4. 5G moving platform backhaul, such as aeroplanes and trains.
We defined business, operational and technical requirements for these use-cases (WP2.2 – WP2.4, D2.2)
We performed quantitative techno-economic analysis of these use-cases (WP2.5, D2.3) as follows
• Economic modelling of computing and networking resource for VNFs and network slicing,
• Modelled each use-case and produced business-specific results,
• Incorporated a ‘broker’ concept for multiple MNOs / SNOs.

WP2 Overview – summary of activities
SaT5G - Satellite And Terrestrial network for 5G
Started with four high level principles from the proposal
• Enable “plug-and-play”,
• Seamless operation at management and security levels,
• Enable eMBB services everywhere and to all market verticals,
• No changes or adaptations needed on user equipment,
We applied this as follows
• Reviewed current satellite services sector to set context for current best practice,
• Assessed the market size for the SaT5G use cases from D2.1,
• Created generic value network to indentify the key players so their needs could be considered,
Made initial observation of possible broker role between MNOs and SNOs,
• Derived SaT5G KPIs from high level 5G PPP KPIs to provide reference for validation activities,
• Reviewed and derived general requirements for business operational and technical.

WP2.2 – 2.4 Requirements
SaT5G - Satellite And Terrestrial network for 5G
Business requirements
• Identify key stakeholders
• Capture stakeholder requirements
• Categorise those requirements
Functional, which are functions that the network must perform
Non-functional, which are aspects such as reliability, regulatory, performance, usability
• Interpret business requirements
Operational requirements
• Operations and management systems
Accounting and Billing
OSS
• Deployment constraints
Cost efficiency, such as shared MNO / SNO costs of remote sites
• Network maintenance
Best practice to support SLAs, change management etc
8
Requirements methodology
SaT5G - Satellite And Terrestrial network for 5G
Technical requirements
• Network management
To follow standardised practices such as those set out by ETSI MANO
• QoS management
End to end QoS using mapping of 5G QCI to Satellite QoS classes
Architectural based requirements. Following the definition of architectures in WP3, the requirements
were refined, examples are:
• Network management, where additional flexibility is provided through orchestration
• Slice management, with dynamic use of compute resources and satellite link resources, and
federated satellite between multiple MNOs.

Main takeaways from the techno-economic analysis
Results show that an integrated satellite-5G network can definitely provide a viable alternative to
terrestrial-only solutions, given that the right use is made of edge caching, slicing and third-party
management.

to serve the CDN nodes versus upgrading the terrestrial network (upgrading copper) or installing fiber
network.

SaT5G - Satellite And Terrestrial network for 5G
Step Description
Identify Key Stakeholders Identify the key people who will be affected by the project (see section 3.4)
Capture Stakeholder Requirements
Ask each of these key stakeholders, or groups of stakeholders, for their requirements from the new product or service. What do they want and expect from this project? We can use several methods to understand and capture these requirements
Categorize Requirementsa The most used approach consists in separating the functionalb and non-functionalc requirements. While dividing the specifications into two neat categories is an orderly way to write the documentation, we should remember that in the real world the functional and non-functional requirements are always tightly intertwined [129].
Interpreting and Recording Requirements
Once we have gathered and categorized all of the requirements, determine which requirements are achievable, and how the system or product can deliver them [131].
33
Business requirement methodology
The SaT5G business solution considered enhanced usage predictions in areas with low ARPUs.
SaT5G - Satellite And Terrestrial network for 5G
Decide what is in and out of scope. Examples of operational requirements that are out of scope
• Spectrum requirements and regulation / sharing
• Taxation, licence fees etc
Consider relevant KPIs. Examples:
• 5GPPP KPI: “Ubiquitous 5G access including in low density areas”
Coverage and availability requirements are generally set by national governments
• Slicing
Enables the application specific parameters to meet the KPIs;
Allows third party managed services for network management;
Enables third party operators to share the site to reduce operator costs in remote regions;
Permits third party managed network security services at cell sites;
Consider legal / safety requirements
• Especially for moving platforms (incurs additional costs)
Needs of the Operational Support Systems of stakeholders, for example
• Accounting and billing
• Network management
34
Operational requirements methodology Back up
SaT5G - Satellite And Terrestrial network for 5G
Deployment constraints
• Cost efficiency - such as network transformation, software upgrades, phasing out of legacy
equipment
Network maintenance
• Managed service provider is responsible for the operational management of the services and
satellite service provider does the installation and of remote segment / local gateway;
• SLA for incident/fault notification and fix times;
• Change management, problem management, technical care support;
• MNO/ third party responsible for spare parts management;
• Contact methods and escalation paths;
SaT5G followed best industry practice, informed through relevant partners (MNO, SNO etc).
