Troubleshooting a complex system such as the EPC relies on a good foundation knowledge of the network and familiarity with the procedures which routinely take place within the network. Based on this knowledge, this course will explore the key KPIs and failure scenarios associated with Accessibility, Retainability and also Mobility. In each case, examples based on the service provider’s own service assurance tools will be explored.
