Authorization Before the Ring: Recipient-Controlled, Pre-Delivery Capability Enforcement Relevant to Nokia and Orange Networks for Anti-Spam Voice/SMS/Email, Agentic Network APIs, AI-RAN, 6G and Satellite Direct-to-Device
Year: 2026
Type: article
Abstract: Phone numbers, SIP URIs and email addresses are open doors: anyone who obtains one can attempt contact. STIR/SHAKEN authenticates the caller but does not decide whether that caller may reach a given person, so correctly signed spam and scam calls still ring. The disclosed architecture adds this missing authorization layer. The recipient’s own secure hardware (SIM/eSIM, eSE, TEE or network HSM) issues a non-routable, non-bearer capability handle. The handle is cryptographically bound to one sender key, a purpose, a time window, a consumable quota, a jurisdiction and a revocation state. A gateway enforcement point (SBC, IMS P-CSCF, SMS firewall, inbound MTA, AMF paging logic, RAN controller or satellite gateway) resolves the handle only through a protected enforcement domain. It validates every constraint before any ringing, paging, alerting, mailbox acceptance or session state occurs. The decision is fail-closed, and a signed validation receipt is committed before every allow or deny. The same pre-effect gate extends to several other areas: AI-agent calls to network APIs (CAMARA, MCP, A2A) AI-native RAN, slice and core actions Latency-bounded URLLC fast paths, with slow-plane signing and microsecond hardware-adjacent checks Silicon execution-envelope verification on GPUs and NPUs Sovereignty-bound cross-border routing LEO/NTN and direct-to-device beam jurisdiction continuity Optical inter-satellite links ISAC sensing release Ambient IoT, reconfigurable intelligent surfaces, radio wake-up/paging and network energy budgets Offline CBDC payments over satellite The disclosure includes pseudocode, indicative latency budgets, threat models (STRIDE), implementation variations and mappings to 3GPP Release 20/21 and IMT-2030. Industry relevance: Orange: Cybersecure anti-scam protection, LiveNet CAMARA APIs, direct-to-device satellite trials, RAN digital twin. Huawei: AI-Centric Network, Agentic Core, Agentic Communication Network, satellite-ground integration. Qualcomm: AI-native 6G with wide-area sensing, Snapdragon modems and secure elements as on-device issuers, agentic devices. NVIDIA: Aerial AI-RAN and accelerated computing for per-output silicon finality. Deutsche Telekom: AI-RAN and 6G platform commitments, network APIs, satellite coverage. Nokia: Network as Code and Network Exposure Platform with agentic AI, AI-native RAN on accelerated computing, 6G AI-native air interface research.
