USING SELF-OPERATION CASES TO IDENTIFY AND RESOLVE ISSUES CAUSING NETWORK SLICE RESELECTION

摘要

A database stores self-operation cases for slice reselection requests received by a network function virtualization (NFV) system. The self-operation cases include reasons, contexts, remedial actions, and results of the remedial actions for the slice reselection requests. A set of detection rules identifies at least one issue causing the slice reselection requests based on reasons for the slice reselection requests and contexts of the slice reselection requests. The set of detection rules are applied to the self-operation cases to identify the at least one issue and a remedial action is selected to address the at least one issue. The remedial action is performed to reconfigure the NFV system and the processor determines whether the remedial action successfully resolved the at least one issue. Setting status flags for affected cells or slices prevents slice reselections to the affected cells or slices until the at least one issue is resolved.
