Troubleshooting the E-UTRAN

This course will utilize your network service assurance tools to discuss methodical approaches to troubleshooting across the LTE E-UTRAN. Protocol level failures associated with S1AP, X2AP, RRC and NAS will all be examined, with exploration of the key KPIs monitored. In addition, issues related to mobility will also be examined, including both intra and inter RAT scenarios. In each case, examples based on the service provider’s own service assurance tools will be explored.
