Hierarchical Mobile Policy Control for QoE Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile Network Operators face challenges in managing finite resources to meet diverse subscriber needs and monetize traffic, as traditional policies fail to enhance quality of experience (QoE) for all users, leading to customer dissatisfaction and increased operational expenditures.
Innovation Solution
A mobile policy hosting system that integrates and implements operator-configured policies across multiple networks, allowing for traffic monitoring, routing, filtering, caching, and regulation, using a cloud-based service that augments existing policy systems without requiring extensive equipment updates, enabling scalable and cost-efficient policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional policy management systems are used, then network resource management is simplified, but quality of experience (QoE) for diverse subscriber needs deteriorates
Solution Approach 1:
The patent segments policy management into hierarchical levels: network-level policies for overall resource management and subscriber-level policies for individual QoE optimization. This segmentation allows the system to handle diverse subscriber needs through customized policies while maintaining simplified network-level control, resolving the contradiction between system simplicity and service quality.
Solution Approach 2:
The patent implements dynamic policy adjustment mechanisms that adapt policies based on real-time network conditions and subscriber behavior patterns. This dynamic approach enables the system to optimize QoE for different subscribers without requiring complex manual configuration, as policies automatically adjust to meet diverse needs while maintaining manageable system complexity.
2Loss of energy
If defensive posture policies are implemented to limit usage, then network resource conservation improves, but customer satisfaction deteriorates
Solution Approach 1:
The patent applies local quality by implementing differentiated policies for different subscriber segments, services, and network conditions. Instead of uniform usage limits, the system applies specific resource management strategies tailored to each context, allowing network conservation where needed while maintaining high service quality for priority subscribers and applications, thus avoiding customer dissatisfaction.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting policy parameters such as bandwidth allocation, priority levels, and resource limits based on network conditions and subscriber profiles. This enables flexible resource conservation that adapts to changing circumstances without imposing rigid usage limits that would harm customer satisfaction.
3Adaptability or versatility
If extensive equipment updates are implemented to enhance policy management, then service capability improves, but operational expenditure increases
Solution Approach 1:
The patent implements a multi-functional policy management platform that handles diverse service requirements through a unified system architecture. This universal platform can manage different service types, subscriber profiles, and network conditions without requiring separate specialized equipment for each function, thereby improving service capability while avoiding the high costs of extensive equipment updates.
Solution Approach 2:
The patent employs virtualization and software-based policy enforcement that creates virtual copies of policy management functions rather than requiring physical hardware updates. This approach enables enhanced service capabilities through software deployments on existing infrastructure, significantly reducing operational expenditures compared to extensive equipment updates.

AI summary
A mobile policy hosting system (MPHS) includes a policy (PCRF) server, an SPR database, and a Billing-Conversion Server. The M PHS enables a mobile network to apply policies otherwise unsupported by the mobile network, thereby augmenting, expanding, or even fully replacing the existing policy services a mobile network. To interface with the M PHS, a new PCEF server is established in the mobile network. The PCRF server in the M PHS transmits a policy name to the new PCEF server in the mobile network so that it can enforce the policy with respect to a subscriber. The Billing-Conversion server converts all monetary information into universally quantifiable measurements (e.g., quantity of data, units of "time," etc.). This enables any mobile network to use the M PHS regardless of the local currency and regardless of the billing/charging interface.
