Small Cell LTE Remote Plugfest 2015

The Small Cell Forum, in partnership with ETSI, has organised the first Small Cell LTE Remote Plugfest from 13 to 24 April 2015.

From all over the world including Europe, Asia and North America, companies connected their equipment to the remote test infrastructure and tested their solutions from their own labs.

The Small Cell LTE Plugfest series aims to drive a multivendor ecosystem by detecting and resolving gaps and ambiguities in standards, while at the same time helping to debug vendor implementations. This helps provide operators and end users with a wider choice of interoperable products, while facilitating the economies of scale required to deliver mass- market small cell deployments.

Registration was open for companies interested in participating to the test sessions with the following equipment:

  • All Small Cell variations: HeNBs, picocells, microcells…
  • Home eNodeB Gateway (HeNB-GW)
  • Evolved Packet Core (ePC)

The main areas of focus of the Small Cell LTE Remote Plugfest 2015 were:

  • Closed subscriber group (CSG), which help to reduce the signaling load on access networks
  • Voice over LTE (VoLTE)
  • Emergency Alerts (CMAS)
  • Mobility

In addition, nice progress was made in LTE-A Carrier Aggregation and Local IP access (LIPA) test descriptions, which is of particular interest to mobile operators as a means of increasing hotspot capacity and reducing traffic load on core networks.

The Plugfest was preceded by a remote pre-testing phase where participants had the opportunity to run regression testing and get familiar with the new test cases.

This was the third event in the series and our first fully remote Plugfest, where participants had the opportunity to run the test sessions from company offices by connecting to the VPN based secure transport network, interconnecting them, deployed by ETSI. This well-established remote test lab was set up at the beginning of the series to support pre-testing phases and participation with remote equipment. Since then, remote test lab techniques and technology have been continuously improved to facilitate enrolment and secure interaction among participants. A flexible LTE network allowed participants to evaluate the interoperability of their solutions with any possible testing partner. Recent enhancements in ETSI’s Plugtests™ tool suite have facilitated interaction among companies and ensured consistent reporting of results.

Over 70 reported test sessions and 500 documented test results have been issued over this two week event.

Remote Plugfests will not replace face to face events since they are required to test radio aspects, for instance, but they will help to reduce the number of meetings, improve their efficiency and contribute to a greener world, an issue ETSI has been keen to integrate in its organization and standards making process.

This activity was supported by the European Commission.

Small Cell LTE Blog

One problem with summer holidays in our industry (or is it a benefit?) is that one tends to let certain things slide and to enjoy more time away from work – whether it be on a formal vacation or just by working a little less than our usual “40 hours” – a very loooong 40 hours – per week. I am certainly guilty of that this summer – and one of the things I am guilty of is not highlighting some really important output from the ETSI MEC ISG. But… as they say… better late than never. So here it goes, but let’s start with background and get to the cool things ETSI MEC produced as we go.

We’ve all heard that “MEC is a 5G technology” although what that means is not exactly clear. In fact, in my very first blog posting, I highlighted that this can lead to some of my (least) favorite “MEC myths”. Here those myths are, re-stated:

  • MEC is a 5G technology, so until I roll-out a 5G network I don’t need to worry about it
  • ETSI MEC will be made irrelevant as soon as 3GPP defines its AF/NEF
  • MEC is only needed before 5G, at which point CUPS (meaning the UPF) replaces it

Side note: yes, the first and third statements are in fact mutually contradicting. But these are myths, they don’t need to be mutually consistent.

Clearly, I disagree with all of these statements, but what is the truth “according to Alex”?

The ZSM interim#1 meeting was hosted by Ericsson on 9-12 July, 2018 at their headquarters in Kista, Sweden, in a meeting room which was named after Hilda, the wife of Ericsson’s founder. The meeting was a good opportunity for the ZSM team to discuss additional scenarios, advance the ZSM architecture work and demonstrate the first ZSM PoC.

ZSM 2018 Interim 1

As described in great-strides-made-by-technical-brainstorming-at-zsm-3, the ZSM architecture supports the separation of management and automation into different areas of concern, i.e. management domains. At the ZSM interim#1 meeting and in follow-up conference calls, agreement was reached on the high-level architecture inside a management domain (depicted in Figure 1 below). Each domain includes functional components (FCs) that perform specific task(s) and expose one or more management services via service interface(s). Some of the services are internal services and can only be consumed by authorized functional components inside the domain. Other services can be exposed and also consumed by authorized functional components outside the domain (including those contained in the E2E service management domain and the digital storefront). The management services within the management domain are assembled into logical groups, such as domain control services, domain orchestration services, domain intelligence services and domain assurance services. The architecture is designed to enable closed-loop automation (connecting assurance and fulfillment processes) where the automated decision-making mechanisms (e.g. self-optimization and automated service assurance) can be bounded by rules and policies.

Kreso Bilan

Kreso Bilan, the SCF IOP WG Chairman concludes this remote event:

"This time we concentrated on regression tests (VoLTE, X2...) and Closed Subscribe Group - to the extent of UEs support for CSG. LIPA/SIPTO and Carrier Aggregation - have seen test cases developed. In addition, we:

  • Reduced the cost of the plugfest (no organising lab for the remote plugfest),
  • Extended the duration of the plugfest (easier planning for SCF members) and
  • Increased convenience for participants (working from their own labs)."
