Abstract:

   Modern telecommunications usually couple knowledge of a routable
   identifier with the practical ability to attempt contact.  A
   telephone number, SIP URI, messaging handle, relay address,
   marketplace contact reference, or similar identifier can therefore
   remain a reusable reachability path after the original purpose for
   disclosure has ended.

   Existing controls solve important but different problems.  Virtual or
   masked numbers hide an underlying endpoint but commonly leave a
   substitute route active while the alias is valid.  STIR and SHAKEN
   authenticate or attest information associated with the calling
   identity, but do not by themselves establish that the authenticated
   caller is presently authorized by the recipient to create this
   particular communication effect.  Combining number masking with STIR/
   SHAKEN improves privacy and origin authenticity, yet still does not
   inherently convert reachability into purpose-scoped, revocable,
   consumable communication authority.  OAuth can express delegated and
   even fine-grained API authorization, including sender-constrained
   tokens, but it does not define telecommunications-specific semantics
   in which a visible contact handle alone creates no effective path
   until recipient-side or policy-bound communication authority is
   established.

   This document describes a Capability-Validated Inbound Descriptor
   (CVID) and related query-scoped communication model.  A communication
   request is represented as a Candidate Act and remains non-effective
   until current authorization is established for the requested
   communication effect.  Authorization may be bound to sender or
   business identity, recipient scope, purpose, channel, time, quota,
   freshness, revocation and policy epochs, jurisdiction, device or
   agent identity, and other deployment-specific constraints.

   Two deployment profiles are distinguished.  In a blocked-path
   profile, ordinary routing may proceed to an enforcement point that
   rejects a request lacking valid communication authority.  In a
   stronger absent-path profile, possession of the visible handle alone
   does not resolve to or activate the effective communication path;
   protected authority must be established before routing, gateway
   resolution, media allocation, notification, or another consequence-
   bearing resource is released.

   The model is relevant to IMT-2030/6G because increasingly
   programmable, AI-assisted, machine-to-machine, and autonomous
   communications can generate requests at machine speed and scale.
   Early rejection or non-creation of unauthorized communication paths
   may reduce unnecessary signaling, gateway processing, fraud-analysis
   load, notification work, media/resource allocation, and associated
   energy consumption.  These are potential efficiency benefits, not
   universal guarantees: authorization itself consumes resources, and
   net bandwidth or energy savings require measurement in the target
   deployment.

   The document focuses on the remaining problem space, comparison with
   existing mechanisms, 6G and sustainability relevance, blocked-path
   and absent-path operation, deployment feasibility, legacy
   interworking, latency considerations, security and privacy, and
   frequently asked questions likely to arise in telecom engineering
   review.
