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

logo_midas_trasp_lowThe MIDAS project aims to implement an integrated framework for the automation and intelligent management of SOA testing. The framework is available as a Platform as a Service (PaaS) on a cloud infrastructure that supports all the testing activities – test generation, execution, result analysis, planning and scheduling – on the main testing domains such as functional, interactional, fault tolerance, security and usage-based testing. The test execution environment is based on a distributed TTCN-3 runtime engine. The adopted testing methods and technologies are beyond the state of the art, particularly on model-based testing, fuzzing for security testing, usage-based testing, probabilistic inference reasoning about test evaluation, planning and scheduling. Two pilot SOA testing experiences in different business domains (healthcare and supply chain management) are carried out.

Small Cell Plugfest LTE event




The Small Cell Forum, in partnership with ETSI, is organizing the first Small Cell LTE Plugfest from the 10th-14th June 2013, hosted by the SINTESIO test lab in Slovenia. Please note that mandatory pre-testing will take place on site the week before (from the 4th to 7th June 2013).

How to register?

Registration is open at the Small Cell LTE Plugfest website:

The event is subsidized to the benefits of the participants and a symbolic fee of 100 EUR per person will be charged. Attendees are responsible for all other associated costs (travel, meals, etc.).

Registration Deadline 8th March 2013

Weekly conference calls will be held each Thursday at 4 PM CET, starting on the 11th of March 2013.

Who’s invited?

All Small Cell LTE systems and sub-system vendors are invited to participate.

Vendors that connect remotely to the Plugfest must send at least one representative on site during the entire event for communication and logistical purposes.

Why attend?

The Small Cell LTE Plugfest will:

— offer on-site and remote test sessions

— cover scenarios on HeNB S1 interface (Initialization – SON, Call Setup/Release, Services, Mobility, Security, Synchronization), and X2 interface

— enable vendors to assess the level of interoperability of their implementations

— verify the correct interpretation of 3GPP and other base specifications

— conduct IoT campaign based on the test cases developed by the Small Cell Forum

We look forward to seeing you at the Small Cell LTE Plugfest!
