第五代移动通信技术之后（B5G）及第六代（6G）网络中的工业服务日益以多阶段工作流形式执行，其服务质量（QoS）需求会随有序阶段变化。现有暴露、分析及策略控制功能可提供能力信息并实施QoS处理，但无法跟踪工作流与网络间已接纳的QoS协议。本文研究软件控制平面中这一缺失的协调功能，提出一种能力代理（Capability Broker），将每个已接纳轨迹表示为经生命周期管理的QoS承诺，包含工作流需求、网络能力、有效期及实施状态。该代理运行于现有暴露和策略控制接口之上，实施能力新鲜度、防重复接纳、合法状态转换、按承诺事件排序、恢复路由及代理-网络状态一致性。通过微基准测试、故障注入、消融实验及受控消息丢失的原型结果显示，完整代理可保持承诺一致性，本地处理开销达微秒级，而移除单个代理功能会引发重复承诺、过期接纳、非法转换、更新丢失分歧或代理-网络不一致问题。
英文摘要
Industrial services in beyond-fifth-generation (B5G) and sixth-generation (6G) networks are increasingly executed as multi-phase workflows whose quality-of-service (QoS) demands change across ordered phases. Existing exposure, analytics, and policy-control functions can provide capability information and enforce QoS treatment, but they do not track the admitted QoS agreement between a workflow and the network. This paper studies this missing coordination function in the software control plane. We propose a Capability Broker that represents each admitted trajectory as a lifecycle-managed QoS commitment, including the workflow demand, network capability, validity time, and enforcement state. The Broker operates above existing exposure and policy-control interfaces and enforces capability freshness, duplicate-safe admission, legal state transitions, per-commitment event ordering, recovery routing, and Broker--network state consistency. Prototype results with microbenchmarks, fault injection, ablation, and controlled message loss show that the full Broker preserves commitment consistency with microsecond-level local processing overhead, while removing individual Broker functions exposes duplicate commitments, stale admissions, illegal transitions, lost-update divergences, or Broker-network inconsistency.
