A new step towards the next generation e-Call

Kranj, November 20, 2020 – With the use of 4G and 5G mobile networks and the announced abandonment of 2G and 3G technology by telecommunications operators, the next generation e-Call is coming. An important step towards its validation represents a successful 3 weeks long international testing event organized under the frameworks of EU co-funded project sAFE and NG eCall Plugtests Event 2020, steered  by ETSI. The testing infrastructure was provided by Slovenian partners in sAFE project, namely interoperability test lab Sintesio as a host and Iskratel as a technical partner.


Iskratel also participated as an active participant in the digital event held under the auspices of the European Telecommunications Standards Institute (ETSI) by performing interoperability tests between its NG eCall Node system and between the in-vehicle system (NG IVS) provided by foreign providers.


The successful 3-weeks event represents an important step in the implementation of the validation of the next generation e-Call conducted in Slovenia, within the European sAFE project. As part of the latter, the partners defined the architectural concept for the next generation e-Call, taking into consideration both, the 3GPP and ETSI standards defining 112 next-generation emergency call on the basis of 3GPP/IMS architecture and Emergency Services Infrastructure Network (ESINet) architecture defined by EENA. Sintesio as the host and Iskratel as the technical partner provided the virtual test environment based on own virtual IMS core network with the support of emergency services.


“Many tests have been carried out that have shown more vagueness, inconsistencies and errors in implementations. With the right support, we managed to eliminate the problems on an ongoing basis and achieved about 75 % of successfully completed tests. This is also the purpose of such an event,” explained dr. Roman Kužnar, director of the Sintesio, Foundation, added that the successfully implemented event also significantly contributes to the completion of the sAFE project.


NG eCall PLUGTEST 2020 is an excellent foundation for further strategic development of broadband “all-IP” networks with the latest 4G and 5G technologies. As a provider of state-of-the-art technologies, Iskratel enables stakeholders to move from older to newer technologies, which ensures long-term compatibility of technologies and consequently lower investment costs.


This NG ECALL PLUGTEST 2020 event, held for the first time in digital format, was organized by ETSI and co-financed by the European Commission and the European Free Trade Association (EFTA) and supported by the European Emergency Number Association (EENA) and the European sAFE project, co-founded by the European Union’s Connecting Europe Facility (CEF) – Transport Sector under grant agreement no. INEA/CEF/TRAN/M2018/179816.


The purpose of the event is to provide e-Call providers of the next generation environment for testing interoperability based on test scenarios defined in ETSI TS 103 683 technical specification. Testing enables the interoperability of the technical solutions provided by multiple vendors, and thus contributed to more successful development, implementation and deployments of the NG eCall solutions in the future.


About the e-Call service

The e-Call service of the next generation will play an important role in saving lives in the event of traffic accidents of various categories of vehicles and upgrades the already introduced e-Call service. From 2018 onwards, it is legally stipulated that all new types of cars and light vans sold in the European Union must have an eCall for an emergency call to 112 installed.


Iskratel and the Sintesio Foundation hosted the eCall Plugtest event in Kranj three years ago. More on this link.

6th eCall TESTFEST

6th eCall TESTFEST

9-13 October 2017



ERTICO in partnership with ETSI and with the support of ETSI TC MSG and ITS Europe is organizing the sixth eCall TESTFEST event, which will take place from 9 to 13 October 2017, in Kranj, Slovenia. This event will be hosted by SINTESIO in cooperation with Iskratel, Public Administration and Telekom Slovenije.

How to register?

Registration is now open at the ETSI website.

All participants must register to the event. Companies registered shall have at least one person on site during the event location.

Registration Deadline and NDA

All participating companies must sign the Non-Disclosure Agreement (NDA) that the official contact will receive upon registration. Companies will not be allowed to participate to the event if the NDA has not been signed. The deadline to return the signed NDAs to ETSI is 31 August 2017.

This activity is supported by the European Commission.


Interoperability and eCall service harmonization are critical challenges to be taken into account for the successful deployment and operation of the eCall service.

The 6th eCall TESTFEST event will enable vendors to run interoperability test sessions using test descriptions provided in approved guidelines.

New In Vehicle System (IVS) and Public Safety Answering Points (PSAP) vendors are invited to join the event.

The event will bring more value with the debriefing sessions where experts can answer technical questions or solve interoperability issues.

Additionally, compliance and performance checking sessions will be scheduled to complement the interoperability tests.

This activity is supported by the European Commission.

Small Cell LTE Plugfest

Kranj, June 10 – 14, 2013 – Small Cell LTE Plugfest was hosted by SINTESIO facillity in Kranj, Slovenia.

This plugfest aimed to verify the interoperability between LTE small cells and Evolved Packet Cores (EPC) equipment from different vendors aim to cultivate an effective ecosystem of standardised small cells (3G, LTE and WiFi).

This helps providing operators and consumers with a wider choice of small cell products while also facilitating economies of scale. LTE small cell deployment will help to solve the user’s demand for ubiquitous coverage on the go and innovative mobile data services with sufficient bandwidth. LTE small cells can evolve in the future to become media gateways in the connected home, thus combining LTE and M2M/IOT technology.

The event was supported by 16 companies including equipment vendors, test tool vendors and companies providing test network infrastructure.

The primary objective of the event, organised by the ETSI Centre for Testing and Interoperability, was to demonstrate the effectiveness of the 3GPP LTE standards in supporting interoperability between small cells and EPC equipment from different vendors.

Companies also had the possibility of connecting remotely for six weeks into the hosting lab to prepare for the event.

The 3GPP LTE Release 9 standards were frozen in December 2009 and are widely used in LTE macro networks. Small cells compliant to the standards allow mobile operators to simplify deployment and enable better coverage and capacity for their LTE networks.

Successful interoperability tests, monitored by test tools, were conducted between small cells and EPCs, security gateways, macro eNodeB and as an option HeNB gateways to verify the S1 interface implementations.

In a multi-vendor HetNet environment – as an option – mobility scenarios of hand-out with the macro network using S1 and X2 interface were tested. VoLTE (IMS) calls were also tested. The Plugfest routinely repeated tests of IPsec/IKEv2 security protocols which allow small cell to communicate over the public Internet to operators’ core networks in a highly secure manner.

Highlights of the Plugfest are:
• All vendors succeeded the mandatory S1 tests
• 2 HeNB vendors succeeded to make a VoLTE call on the dedicated bearer using Iskratel IMS
• 3 HeNB vendors succeeded S1 small cell to macro handout with TS eNB
o inter: band 1 small cell to band 3 macro
o intra: band 3 small cell to band 3 macro, same frequency
o inter: band 3 small cell to band 3 macro, different frequency
• 2 HeNB vendor succeeded S1 small cell to small cell handover with TS EPC
o intra: band 1 small cell and band 1 small cell, same frequency
o inter: band 1 small cell and band 3 small cell, different frequency
• 1 vendor succeeded X2 small cell to macro handout with TS eNB
