Master-Slave Policy Control for Mobile Network Resource Bottlenecks

The patent extracts the policy control functionality from external servers and relocates it to user devices themselves. Each device stores and executes local policy rules, eliminating the need to reroute traffic through external filtering servers. This extraction resolves the contradiction by maintaining content control capability while removing the latency-causing traffic redirection mechanism.

The patent introduces a local policy control entity as an intermediary within the device that mediates between network traffic and content control requirements. This local mediator processes policy decisions device-side without requiring external server communication, thus maintaining control reliability while eliminating the time loss associated with server-based filtering.

The patent segments the centralized policy control system into distributed local policy control entities across multiple devices. Each device independently stores and executes policy rules locally, so the failure or unavailability of any single device does not affect others. This segmentation maintains service availability while preserving centralized management through the distribution of policy templates from a central source to individual devices.

Each user device is equipped with self-service capability to execute policy control locally without continuous external server assistance. The device autonomously applies stored policy rules to filter content and manage network resources, ensuring service availability even when external servers are unavailable. This self-service approach resolves the contradiction by maintaining centralized policy distribution while enabling independent local execution.

The patent extracts the content filtering function from external servers and implements it locally within user devices. By taking out the filtering operation from the network path and placing it at the endpoint, the system maintains filtering effectiveness while eliminating the need to reroute traffic through intermediate servers, thus preserving data transfer efficiency.

The patent copies policy control functionality from external servers to local devices. Instead of routing traffic through servers, each device receives and stores copies of policy rules locally, then executes filtering independently. This copying approach maintains filtering effectiveness while avoiding the performance degradation caused by server-based traffic interception and rerouting.

The patent implements a universal policy control framework where a single policy template can be distributed to and executed on multiple devices simultaneously. The system uses device identifiers and group management to apply comprehensive control across device families or groups without requiring separate complex configurations for each device. This universality achieves multi-device control capability while minimizing system complexity through standardized policy templates.

The patent copies policy control templates from a central management system to multiple user devices. Instead of configuring each device individually with complex settings, the system creates standardized policy templates that can be replicated across devices. This copying mechanism achieves comprehensive multi-device control while keeping individual device complexity low through template-based configuration.
