Message Content Filters for Differentiated Service Policy Enforcement

The patent segments policy application by introducing message content filters that divide consumers into different groups based on their message characteristics. Instead of applying a single uniform policy to all consumers, the system segments the consumer base and applies different policies to different segments, enabling service customization while maintaining manageable policy structures through filter-based classification.

The patent implements local quality by allowing different policy treatments for different consumers based on their specific message content characteristics. Each consumer receives a policy tailored to their message properties (such as message type, priority, or content category), rather than a uniform policy, thus customizing service quality locally for each consumer segment while maintaining overall system coherence.

The patent introduces message content filters as an intermediary mechanism between uniform policy definitions and consumer-specific policy application. The filters act as mediators that automatically classify consumers based on their message characteristics and route them to appropriate policy sets, thereby achieving consumer-specific service levels without requiring complex manual policy enforcement for each consumer.

The system implements self-service by enabling consumers to effectively select their own policy treatment through the characteristics of their messages. The message content filters automatically evaluate message properties and apply appropriate policies without requiring manual intervention, allowing the system to self-regulate policy application based on inherent message characteristics.

The patent applies preliminary action by pre-configuring message content filters with classification rules before policy enforcement. The filters are prepared in advance with defined criteria for evaluating message characteristics, so that when messages arrive, the system can quickly match them against pre-established filter rules and apply appropriate policies without complex real-time decision-making.

The patent utilizes parameter changes by varying filter evaluation criteria based on different message attributes (such as message type, priority level, or content category). By changing the parameters evaluated by filters according to message characteristics, the system achieves fine-grained policy differentiation while maintaining manageable filter complexity through parameter-based classification rather than complex rule structures.
