5GEx virtualization-based multi-domain roaming

In the context of the 5GEx project, a new and novel solution for roaming in cellular mobile networks has been developed, implemented and validated. The solution is based on dynamically deploying a virtual instance of the PGW (Packet Data Network Gateway), which is the  data plane entity anchoring all traffic of a UE, on the visited domain. In this way, roaming users’ traffic no longer needs to reach the home domain, traversing the network between the visited and home  domain. The trigger for the virtual PGW instantiation is configurable and  can be based on multiple factors.

The virtual PGW instance is actually managed and owned by the home operator, which allows to overcome some of the main limitations  of the currently standardized local breakout solutions, namely (i) issues with incompatible charging systems between home and visited operator systems, and (ii) lawful interception obligations of the home  operator.

The solution has been implemented using the multi-domain orchestration solution from 5GEx and evaluated on 5TONIC (https://www.5tonic.org/). This has been shown in different events already, such as MVNOs World Congress 2018 (https://tmt.knect365.com/mvnos-world-congress/), Network Virtualization Europe (https://tmt.knect365.com/virtualization-sdn-europe/), EuCNC 2018 (https://www.eucnc.eu/) and ISNCC 2018 (http://www.isncc-conf.org/).

Special Sessions

5GEx participated at the Special Session 5, entitled 5G Architecture towards Verticals

5G is the first generation of mobile networks that is by design addressing the wide range of needs of the vertical industries. 5G offers unlimited mobile broadband experience, provides massive connectivity for everything from human held smart devices to sensors and machines, and most importantly, it has the ability to support critical machine communication with instant action and ultra-high reliability.

The first 5G specifications are available with 3GPP Rel.15, but further enhancements and optimization are needed to design a 5G System that meets the requirements from the vertical industries. In this special session, pitches from vertical industries, operators and vendors were collected to trigger a panel discussion on the above aspects.

In this special session, Carlos Bernardos and Diego López participated from 5GEx project.

EuCNC Exhibition & Booth

Recap of the 2nd 5GEx Industrial Workshop

Our workshop was part of the 6th Annual  Network Virtualization Europe conference (May 22-24, Madrid) organized by KNect365 TMT, an Informa business. We supported the organization of the “Track B: Service Assurance & MANO” and were present as supporting organization on all communication material, which helped a lot to attract people joining presentations, discussions and the demonstration of the 5GEx GiLAN use case.

Our two presentations were given by Hakon Lonsethagen on business aspects in a “Multi-provider services and automated orchestration by the 5G Exchange Service Layer” (summary of section 3 and 4 of D2.3) and by Dr. Carlos J. Bernardos on architecture aspects with detailed explanation on the example use case GiLAN (“Roaming in an NFV-enabled multi-operator world”). Both presentations have been very well received by the audience. Especially the first one was reflected in the Service Assurance & MANO track in the panel discussion on “Orchestration Strategy and Challenge”. The panel included a mixture of 5GEx partners with Telefonica, Telenor and Telecom Italia and leading industrial players like CableLabs or EXFO.  Some of the discussed aspects are:

  • Dealing with continuous development leads to frequently new aspects and problems (e.g. problems in ETSI NFV standards for closed loop orchestration)
  • Status of maturity of virtualized network functions (agreement that it improves)
    • Education and training is very important, change of people minds underestimated
    • Change of organizational culture is still important, transformation is not a problem of weeks or months
      • Resiliency is of higher importance in telco word than in IT world, this should especially regarded by developers
      • Adoption of mature technologies takes sometimes time, e.g. TCP flow control is debated for several decades now

The high-level introduction of the 5GEx architecture and presentation of the GiLAN use case was very successful. There have been a lot of employees of mobile operators at the conference (in fact, these persons are representing 20-30% of all mobile customers in the world) and the GiLAN use case attracted their interest. So, we had counted in total 40 visitors, ten demos and gave away 25 white papers. The feedback was very positive, acknowledging the interesting idea and accepting that multi-provider NFV is something of importance for the future. There have been many detailed discussion, ranging from the detailed technical standards for mobile Internet connectivity to options in deploying the virtualized network functions.
