This book outlines a VoLTE (Voice over Long Term Evolution) test plan that ensures a correct, stable, and effective VoLTE deployment. These scenarios cover major functional and characterization requirements of a VoLTE network. Each test provides a description, test steps, and expected results. The test plan provides significant benefits when executed before deployment, and also as part of an ongoing regression environment as network elements are upgraded and expanded over the network lifetime. This book is a collection of input gathered from our work with leading equipment vendors and mobile operators globally.
