AI 中文摘要
基于意图的网络管理是6G服务生命周期自动化的新兴范式，3GPP意图管理框架定义了创建、翻译、实现和保证阶段。现有实现和保证方法与多租户网络的监管约束及多供应商O-RAN部署中的供应商不透明性存在冲突。本文提出一种隐私保护意图实现与保证架构，协调器无需流量检查即可根据声明的意图类别分配资源，并仅使用O1接口的聚合标准化性能监测计数器来验证实现情况。通过数据处理不等式论证表明，资源分配最多揭示关于流量内容的\(\log_2 K\)比特信息。定义了两种架构隐私属性，即意图-流量不可链接性和节点不透明验证，并通过构造证明它们成立。节点不透明性不牺牲检测能力。将该架构映射到3GPP意图生命周期和O-RAN非实时RIC上，确定了机制运行的具体接口、数据对象和部署点。在来自四个运营商网络的生产性能监测计数器数据上，增加意图类别粒度会增强分配但削弱保证，这与隐私上限是检测约束的结构副作用而非单独设计参数的理论预测一致。
英文摘要
Intent-based network management is the emerging paradigm for 6G service lifecycle automation, with the 3GPP intent management framework (TS~28.312) defining creation, translation, fulfilment, and assurance stages. Existing fulfilment and assurance approaches require deep packet inspection, per-flow state tracking, or access to vendor-internal node telemetry to verify that provisioned resources satisfy expressed intents. These requirements conflict with regulatory constraints (GDPR, ePrivacy Directive) in multi-tenant networks and with vendor opacity in multi-vendor O-RAN deployments. We present an architecture for privacy-preserving intent fulfilment and assurance in which a coordinator provisions resources from declared intent categories without traffic inspection, and verifies fulfilment using only aggregate standardised PM counters at the O1 interface. A data-processing inequality argument shows that the resource allocation reveals at most $\log_2 K$ bits about traffic content, where $K$ is the number of intent categories. We define two architectural privacy properties, intent-traffic unlinkability and node-opaque verification, and show that both hold by construction. Node-opacity does not sacrifice detection power: the aggregate verifier weakly dominates the per-agent verifier under a homogeneity condition. We map the architecture to the 3GPP intent lifecycle and the O-RAN Non-RT RIC, identifying the concrete interfaces, data objects, and deployment points at which the mechanism operates. On production PM counter data from four operator networks, increasing intent-category granularity sharpens provisioning but weakens assurance, consistent with the theoretical prediction that the privacy ceiling is a structural side effect of the detection constraint rather than a separate design parameter.
