Current Third Generation Partnership Project (3GPP) and Global System for Mobile Communications Association (GSMA) standards require establishing generic slice templates for each Service Provider (SP) worldwide in order to enable Fifth Generation (5G) slicing in Local Break Out (LBO) (roaming) scenarios. In current standards-based deployments, templates have to be shared among all 5G SPs in order to enable 5G roaming. As a result, it can be difficult to create, separate, and maintain various slice templates inside an SP network. Provided herein is a technique to enable 5G slicing for roaming subscribers using predefined slices that can be mapped by an Access and Mobility Management Function (AMF).
