Accounting/Billing Services TRIZ Cases
- Unified Wireless Number Routing Across Separate Carrier Billing
An identifier-mapping layer links one phone number to devices on different carriers while routing traffic correctly and keeping billing separate.
- Restricted Access Enrollment for Secure Service Gateway Switching
A restricted access mode verifies user identity before switching gateway identifiers, securing service enrollment without repeated checks.
- VoWiFi Registration Control Using Position Verification in Roaming
Position-based verification stops mismatched VoWiFi registration in roaming, helping prevent charging disputes and billing errors.
- MaaS Roaming Authentication Using Decentralized Identity Credentials
Decentralized identity credentials enable MaaS roaming across providers without separate tickets, reducing personal data exposure and central authority dependence.
- Reverse Geocoding with Mercator Projection for Fast POI Search
Mercator-projected Cartesian coordinates and an R-tree speed nearby point-of-interest lookup for real-time mobile RUM analysis.
- Managed SIM Activity Notifications for Parent Device Monitoring
A virtual bind system flags SIM status, billing, and disconnection events so parent devices get timely alerts without constant child-device monitoring.
- Network Slice Instantiation With Integrated Charging Profiles
Charging profiles are built into network slice instantiation to enable accurate real-time or per-session charging with lower latency.
- Vehicle Network Authentication for Temporary Secure Transactions
Pre-established trust and certificate checks let a vehicle device join an authorized wireless network quickly, validate a transaction, and disconnect.
- Proximity Communication Resource Reporting for Accurate Charging
By reporting air interface resource use in proximity communication, terminals enable more accurate network charging than data-volume billing.
- SIM Networking Intermediary for Encrypted Threat-Protected Access
An intermediary SIM networking service adds end-to-end encryption, DNS threat filtering, and flexible routing to protect data and user privacy.
- Network Exposure Function Session Billing for Wireless Data Delivery
Prompt session-data retrieval lets the Network Exposure Function expose service charges after delivery for timely wireless billing.
- Virtual Core Network Service Control for Dual Access
A virtual core network dynamically adjusts charging and quality of service as terminals select WLAN or base-station access.
