GSMA eUICC interoperability in the age of acceleration

The age of acceleration

Christmas presents are full of surprise, this is what they should be. My under the tree packages included a book this year, Thank You for Being Late  by Thomas L. Friedman, This page-turner diagnoses the “age of acceleration”, an unprecedented historical moment that promises to transform almost every aspect of modern life, from how we hail a taxi to the fate of the nations to our most intimate relationships. The exponential increase of power, defined by Moore’s law, has a lot to do with it while the data flows generated by the scaling of internet of things (IoT) and machines starting to talk to machines (M2M), will create a larger impact on growth than traditional goods flow.

To provide the best environment for Friedman’s acceleration prediction, Communications Service Providers (CSPs) and Enterprises need to enable devices with the ability to connect instantly and adapt this connectivity on the go. In the business of connecting IoT or M2M devices globally via a cellular or WIFI solution, you can’t overlook the embedded subscriber identity module (eSIM) or Embedded Universal Integrated Circuit Card (eUICC), . The past 12 months showed an increase in CSPs and enterprises’ interests in eUICC as an alternative to removable SIM cards. This is particularly true for use cases such as automotive, fleet and asset management, and industrial automation. Simply put, the eUICC helps future-proof connected business and enables the growth of connectivity beyond the initial transaction with easy recycling capabilities for a second-hand market place.

A lot of pieces need to come together to make IoT/M2M solutions cost effective. The ecosystem involves CSPs, device manufacturers, and sensor manufacturers, SIM card providers, IoT/M2M applications, platform providers, and system integrators.

 The GSMA Embedded SIM Specification provides a mature standard which now has been proven to be secure, scalable, robust and fully interoperable between industry suppliers’ products. Enterprises looking to leverage on GSMA specifications can securely and remotely provision their IoT/M2M devices ‘over the air’ and easily change CSPs after launch to market. 

Discover the GSMA Interoperability project by listening to Arnaud Danree, Executive Director, Embedded SIM, Connected Living, GSMA.

 HPE has actively participated in several off-line and on-line proof of concepts that demonstrate that different subscription manager solutions are now fully interoperable and that it is possible to switch between different CSP frameworks.

 For example, we have demonstrated the subscription manager switch process, in which a given subscription manager secure routing (SM-SR, an entity that will securely deliver the encrypted CSP’s credentials to the SIM) from one CSP framework, can be replaced by another SM-SR from another CSP framework (See Figure 1) - for example from the SM bootstrap service provider to the operational Service Provider.

 At the end of this switch, the new subscription manager will be able to provide the new CSP connectivity services having remotely downloaded via a subscriber manager data preparation (SM-DP) the new CSP profile to the eUICC. At the end of the procedure, the eUICC is now attached to the SM-SR accessed by the new CSP. 

The successful interoperability testing for GSMA remote SIM provisioning for M2M assures customers that they are not locked in to any one connectivity or technology provider.

 Why a connectivity management platform?

 The need for self-service management for IoT/M2M enterprise customers becomes increasingly critical as the IoT/M2M market grows, along with the number of small to medium-sized vendors requesting SIM cards and increased services.

 eUICC Four.pngA connectivity management platform provides the first step that CSPs need to build some value added services for their M2M/IoT Enterprise customers on top of their core connectivity services. The platform fits between the connectivity layer and the application enablement platform into the end to end solution stack that is required to deliver end to end M2M/IoT services.

 With the HPE Dynamic SIM Provisioning - Connectivity Management Platform  (CMP), B2B subscribers have access to a CSP self-service portal for IoT/M2M SIM and eUICC subscriptions that creates and enforces differentiating subscription packages for their specific needs.

HPE DSP - CMP is pre-integrated, reducing implementation effort and risk, and improving time to market. It is SIM vendor agnostic, based on network standards and provides for a well-defined evolution toward a complete M2M service framework.

 And pause….

 As his book title suggests, Thomas Friedman makes an argument for “being late”, pausing to appreciate the amazing historical epoch we’re passing through and to reflect on its endless possibilities. If you are planning to go to Mobile World Congress this year, I invite you to do the same, one morning in Barcelona, while admiring the sun rising over the Mediterranean Sea. That day, you might be late…
