Accounting/Billing Services TRIZ Cases
- PCNE Roaming Policy Negotiation and Enforcement
A virtualized PCNE normalizes policies across home and visited networks to enforce real-time charging rules.
- Unified Core Network Slicing for Multi-Operator Isolation
Segmented virtual network functions isolate multiple operators on shared hardware, reducing deployment complexity while maintaining strict security boundaries.
- Network Cloud Service Decoupling User Authentication from Device Hardware
A network cloud service synchronizes user configuration data to any device upon login, enabling cellular communication access without physical subscriber identity modules.
- IMS Charging ID Correlation via Orig-ICID Nesting
Embedding original charging identifiers in retargeted SIP messages enables accurate data correlation and network tracing despite complex call leg routing.
- Diameter Roaming Gateway for MVNO Selection and Billing
A Diameter Roaming Gateway routes service requests to appropriate mobile virtual network operators based on location and availability.
- Idle-Time Ad Display for Mobile Devices
A display system loads graphic advertisements onto a mobile device to show them during idle periods.
- Multi-Bus Storage Device with Arbitration Circuitry for External Data Access
Arbitration and isolation circuitry in a multi-bus storage component allows external devices to read and write data when the primary host is powered off.
- On-Demand Roaming Hub for Seamless Cellular Wi-Fi Transition
A roaming hub detects third-party access points and negotiates dynamic subscriptions to enable user device connectivity.
- Diameter Routing Agent Credit Status Triggered Policy Control
A Diameter Routing Agent monitors credit control messages to notify the Policy and Charging Rules Function of subscriber credit thresholds.
- IoT Services Architecture Dynamic IMSI Switching
Embedded subscriber identity modules allow global service providers to dynamically switch network operators based on real-time data traffic inspections.
- User Equipment Network Switching via Call Failure Counters
User equipment monitors voice call connectivity to trigger switching between LTE and legacy networks when failure thresholds are met.
- Wireless Account Management Application for Real-Time Usage Tracking
A wireless account management application receives usage data and account information to enable direct service purchases on mobile devices.
- PDSN Counter Limits Billing for Undelivered Data
A packet data serving node counter stops recording sent data volume when no active traffic channel exists.
- CAMEL Adaptation System for Roaming Protocol Translation
A CAMEL Adaptation System interfaces Home and Visited Public Mobile Networks to standardize roaming protocols.
- Real-Time Network Consumption Tracking via Message Bus
A charging function device publishes formatted event messages to a message bus for external system access.
- Network Gateway Gx Session Backup for PCF Failure
A network gateway establishes a backup Gx session with a standby Policy Control Function to maintain communication sessions.
