This context is the record that lets the SMSF route mobile-originated and mobile-terminated messages for that subscriber. The SMSF creates, updates, and deletes it through Nsmsf_SMService.<\/p><h2>Addressing Registration Dependencies in the 5G Core<\/h2><p>The problem with registration is coupling. If the SMSF waits for the UDM before answering the AMF, a slow or failed UDM becomes a core-wide delay. As standalone networks grow, that dependency becomes a risk for every subscriber, not just the ones being registered.<\/p><h2>How PAiCore SMSF Handles Registration Events<\/h2><p>PAiCore\u2019s SMSF Module v1.0.0 keys each registration event by SUPI and forwards REGISTER and DEREGISTER events to the UDM through Nudm_UECM. The AMF-facing path stays synchronous, while UDM forwarding runs asynchronously in the registration service.<\/p><p>An outage in the UDM does not hold up the AMF. The registration service retries the UDM update on its own schedule.<\/p><h2>Ensuring Consistent Subscriber Context Management<\/h2><p>The UE SMS context uses ETag-based conditional updates and deletion, so two concurrent changes do not silently overwrite each other. NRF discovery lets the registration service find the correct UDM for each subscriber without hard-coded addresses.<\/p><h2>Independent Services for Greater Scalability<\/h2><p>Because the registration service and the mobile-terminated delivery service are separate deployments, operators can scale one without touching the other. Capacity added for a registration surge during a network launch does not change the delivery path.<\/p><div>\u00a0<\/div><p>News source: Opensignal, \u201c5G Standalone in Europe: Where deployment
