"Mavenir and Rakuten designed the Link app to go beyond the 3GPP definitions, thereby enabling MNOs to directly compete with OTT players."


Rakuten is a diversified business and wanted to use its mobile network to increase customer engagement with its other brands to achieve long-term growth. To do this, it partnered with Mavenir to build an OTT app, which not only delivers voice and video services, but improves interactions with other parts of Rakuten's business.

This case study provides:

  • an overview of the challenges faced by Rakuten Mobile
  • an analysis of the opportunities that the Link solution provides (beyond just voice and video services)
  • implementation details of an IMS-less voice app.
