Subscription Services TRIZ Cases
- E2 Node UE ID Signaling for RIC Service Differentiation
Event-driven UE ID signaling through E2 nodes lets the RIC manage users more precisely for resource allocation and differentiated services.
- RAN UE Identifier Mapping for Dynamic Per-User Policy Control
A new RAN-management interface maps UE identifiers to enable per-user observability and dynamic policy control without changing legacy SPID and QCI models.
- SIM Application Management for Targeted Subscriber Customization
Direct SIM app control targets active subscribers only, cutting unused card storage and avoiding unnecessary customization costs.
- SIM Card Information Loading via Plug-In Modules in SystemUI
Operator-specific plug-in modules decouple SIM info loading from SystemUI, improving reuse, version adaptation, and loading performance.
- E2 Node Subscription Signaling for RIC UE Identifier Management
Event-driven E2 node signaling sends higher-node UE identifiers to the RIC, improving wide-area user tracking and service differentiation.
- eUICC Profile Reinstallation for Seamless Operator Switching
Remote eUICC profile download and reinstallation removes physical SIM replacement, cutting switching time, cost, and user inconvenience.
- E2 Service Model Abstraction for O-RAN xApp Interoperability
An abstraction layer maps xApp KPI requests to E2-node service models, reducing version monitoring and subscription complexity in O-RAN.
- Application Relocation Using UE Location After PDU Path Changes
When DNS cannot identify the best server after a PDU path change, a source application function uses UE location to shorten access delays.
- Dynamic PLMN/NPN Service Unsubscription for Resource and DoS Control
Dynamic UE deregistration from PLMN/NPN services helps conserve network resources and limit DoS exposure.
- Near-RT RIC Subscription Auditing for E2 Node Synchronization
Near-RT RIC audit requests and responses use RAN function and RIC request IDs to synchronize E2 node subscriptions.
- USIM Management Device Usage-Based Replacement Logic
A USIM management device tracks usage counters to determine replacement timing for industrial terminals.
- Virtual SIM Marketplace Dynamic Provisioning
A virtual SIM marketplace matches user requests with service providers to enable over-the-air provisioning of subscriber identity modules.
- Mobile Accelerator System Optimizing Data Transfer via Dedicated POP Connections
A mobile accelerator system routes data through dedicated point-of-presence connections to enhance transfer speeds.
- Virtual SIM Data Allocation for Mobile Network Conflict Reduction
A virtual SIM management system allocates subscriber data to mobile terminals based on usage probability and historical outbound proportions.
- eUICC Command Processing Consolidates Refresh Operations
An eUICC consolidates multiple refresh commands into a single operation to streamline profile management execution.
- eUICC Remote Profile Management for 5G IoT Service Switching
An embedded universal integrated circuit card downloads communication profiles from a mediation server to enable seamless service switching.
- eSIM Profile Selection for External Device Network Access
Embedded UICC selects subscriber profiles to provide network service, eliminating physical SIM slots and reducing device complexity.
