ETSI has announced the publication of ETSI TS 103 480, a new Technical Specification that establishes a framework for interoperability testing across next-generation emergency communications networks. The specification provides a standardised methodology to ensure that systems from different vendors can operate seamlessly, enabling reliable access to emergency and life-saving services across Europe and beyond.

As emergency communications shift towards next-generation architectures, ensuring interoperability has never been more critical. The specification describes interoperability tests enabling network-independent access to emergency services, including:

• verifying end-to-end interoperability between originating services

• testing location and transport procedures

• validating routing and policy functions

• providing a basis for standardised laboratory testing

It also ensures that essential functionalities such as location delivery, Advanced Mobile Location (AML) and multimedia communication are transmitted so that emergency responders receive the right information on time.

“Interoperability is fundamental to the effectiveness of emergency communications,” said Cristina Lumbreras, Chair of the ETSI Emergency Communications Technical Committee. “With this new specification, ETSI provides the industry with a practical and harmonised approach that ensures citizens can reliably access emergency services regardless of the network, device or medium (e.g. voice, video and text) they use.”

ETSI continues to play a central role in advancing emergency communications across Europe and globally. Its specifications have supported the development of:

• Advanced Mobile Location (AML), enabling accurate caller location information to be transmitted to emergency services

• eCall, which has been mandatory in all new cars since March 2018, automatically alerting emergency services in the event of a serious accident

• Next Generation 112, enabling multimedia emergency communications in a standardised way, including voice access, NG eCall, real-time text and video communications

• Public Warning Systems, supporting the delivery of alerts to citizens during emergencies

By combining these initiatives with robust interoperability testing, ETSI helps ensure that emergency communications systems can operate cohesively across borders and technologies, strengthening public safety and trust among network vendors and service providers.

To support industry adoption, ETSI invites stakeholders to participate in its upcoming Plugtests™ events, a collaborative environment for testing implementations in real-world scenarios.
