ENTITLEMENT SERVER AS A SERVICE
Entitlement-Server-as-a-Service that arrives in time.
The real-time GSMA TS.43 entitlement decision layer for mobile operators — behind Wi-Fi Calling, VoLTE, eSIM and multi-device, delivered as a managed service. Every capability exists to remove a specific cost or a specific failure from your operation.
DEFINITION
What is Entitlement-Server-as-a-Service?
Entitlement-Server-as-a-Service is a managed platform that makes real-time entitlement decisions for your subscribers. It determines whether a given subscriber, on a given device, in a given market, can use services like Wi-Fi Calling, VoLTE, or eSIM.

The platform handles the GSMA TS.43 protocol layer without replacing your existing BSS or systems.
CORE PLATFORM
Simplified capabilities, structural security.
Answers that arrive in time
The decision layer every service depends on — and that holds up when your upstream systems do not.
Cache-first decision engine
Policy as versioned configuration
Multi-source truth resolution
Fail-safe policy per service class
The device side, absorbed
The part that changes constantly across handsets and specifications — and the reason operators stop wanting to own it.
TS.43 device edge
Activation orchestration
Network & fallback authentication
eSIM ordering & transfer
Your systems keep their interfaces
No BSS replacement. No data migration. No new system of record.
Six defined southbound ports
Anti-corruption adapter layer
Resilience in every adapter
Operator secure edge
Built for the security review
The capabilities procurement and your CISO ask about first — answered structurally, not by assertion.
Four isolation tiers
Residency by construction
Immutable decision audit
Per-tenant observability

WHAT IT MEANS FOR YOUR TEAM
The benefit, by who feels it
Network & technology
Standards conformance and availability engineering maintained continuously, with fail-safe behaviour chosen deliberately on the emergency path.
Device management
OEM certification absorbed. New handset families validated before your subscribers meet them — without a lab on your balance sheet.
Consumer products
New services launch without a platform programme behind them. Attach rate and switch conversion become things you can move.
BSS & IT
Six defined integration points. Your systems keep their interfaces, and no subscriber data migrates anywhere.
Security & compliance
Isolation tier of your choosing, residency enforced by construction, credentials held in your environment, every decision auditable.
Customer care
Any entitlement answer explainable per subscriber, per device, with the reason recorded. Escalations to network engineering drop.
WHY US
Structural answers, not assertions
The claims that matter to an operator are the ones built into the architecture — where the alternative is a promise in a contract.
Safety
Fail-safe on the emergency path
Security
Credentials never leave your estate
Autonomy
Policy you version yourself
Low risk
No BSS replacement
Cost
Metering you can audit
Opex
The device side, off your books
FREQUENTLY ASKED QUESTIONS
Entitlement-Server-as-a-Service, answered

What is Entitlements-as-a-Service (EaaS)?

Entitlements-as-a-Service is a managed platform that makes the real-time entitlement decision — whether a given subscriber, on a given device, in a given market, may use a service such as Wi-Fi Calling, VoLTE or eSIM — and handles the device-facing TS.43 protocol, so mobile operators do not build or run that layer themselves. It connects to the operator's existing systems through defined ports rather than replacing them.

How is EaaS different from an entitlement server?

An entitlement server is a product you deploy and operate. Entitlements-as-a-Service delivers the same underlying capability as a managed, multi-tenant service — with the device lifecycle, OEM certification and operational assurance absorbed — so the operator consumes the decision layer rather than running the software.

What is GSMA TS.43?

GSMA TS.43 is the Service Entitlement Configuration standard that devices use to check whether a network service is authorised. U2opia's TS.43 device edge supports multiple specification versions concurrently and handles per-OEM behaviour, so handsets already in the field keep working when the specification moves.

Do we have to replace our BSS?

No. The platform connects through six defined integration ports — subscriber data, network identity, provisioning, SIM provisioning, charging and notification. Your BSS keeps its interfaces, and no subscriber data is migrated to a new system of record.

Where does our subscriber data live?

In the jurisdiction you nominate. Residency is enforced by construction, with four isolation tiers up to deployment inside your own estate, and operator credentials held at a secure edge within your environment.

Which services can we launch first?

Wave 1 covers services that need no new commercial construct — Wi-Fi Calling, VoLTE and VoNR, and a smartwatch on one number — proving the full path on your network against a metric you already track before any monetisation work begins.

How is it priced?

Metering is per billable decision, defined precisely. Cache hits inside a validity window are not charged, so cost tracks usage rather than your total subscriber count — and you can audit your own bill.
