INTEROPERABILITY

high level objectives

harmonized strategy

aligned operations

aligned procedures

knowledge

Information interop.

data model interop.

protocol interoperability

physical interoperability

organizational aspects

technical aspects

Interoperability

• Different needs – From citizens in commercial networks to FR private networks

• Interoperability levels

– Organizational – Regional/national/cross-border – Main aspects to consider

• Practices • Information Security • Legislation • OAM procedures

• Technical interoperability

– Current incompatibilities (technologies, implementations) – Backwards compatibility – Convergence

• Information Exchange

– User groups, identities, security constrains, location

Requirements and Design principles

• R1: Address different types of PMRs and citizens.

• R2: Basic and enhanced services.

• R3: Interoperability of both legacy and next generation emergency networks

• R4: Internal access to enhanced services with legacy equipment.

• R5: Ensure autonomous (per-organization) management.

• R6: Preserve Information ownership/access rights.

• R7: Easily allow trans-national/regional communications.

• R8: Enable the connection of significantly different organizations.

• R9: Allow different business models.

• R10: Integrate recording and location tracking capabilities.

• R11: Harmonize user priorities.

• R12: Not affect existing internal procedures.

• R13: Ensure efficient operation.

• R14: Permit the integration of an intermediary control room for emergency communications.

• DP1: Multi-domain ecosystem

• DP2: Standardized IP based “core network”

• DP3: Optimized technology independent operations

• DP4: Enable IP-Level Mobile Virtual Network Operator (MVNO)

• DP5: Session Border Control-like

• DP6: Common technology independent naming and call routing.

• DP7: Avoid any assumption.

• DP8: Scalability

• DP9: Controlled access

• DP10: Orchestrate the use of resources

• DP11: Flexible multi-level dispatching .

• DP12: Rely on OAM for inter-agencies operations .

• DP13: Enable recording and location tracking mechanisms.

• DP14: Ease citizens’ access to the interoperability services.

The Over The Top proposal

• Technology agnostic

– Regardless underlying network

• IP based

• Software solution

• Cost effective and convergence enabler

• Need for harmonization!!!

– Current initiatives focused on low level IoT but… emergency services?
