Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient mechanisms for power status reporting and optimized service configuration in wireless transmit/receive units (WTRUs), leading to suboptimal resource allocation and battery management in multi-modal data environments.
Innovation Solution
Implementing power reporting policies in WTRUs and network devices that include triggers for power status reporting based on battery level, temperature, bitrate, and application status, allowing for dynamic configuration of PCC rules and QoS settings to optimize power consumption and service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power status reporting is implemented frequently to improve battery management, then battery management efficiency is improved, but network signaling overhead and device power consumption increase
Solution Approach 1:
The patent implements dynamic power reporting policies where the reporting frequency and triggers are adjusted based on current battery status, network conditions, and service requirements. The network can configure different reporting intervals and triggers (e.g., threshold-based reporting) to balance battery management needs against signaling overhead, making the system adaptable rather than static.
Solution Approach 2:
The patent changes key parameters such as reporting frequency, trigger thresholds, and policy conditions to optimize the balance between battery management efficiency and signaling overhead. By adjusting these parameters dynamically based on device state and network conditions, the system achieves efficient battery management without excessive signaling.
2Measurement precision
If power reporting policies are configured to monitor multiple parameters (battery level, temperature, bitrate), then power status accuracy is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments the power status monitoring into modular components, where different parameters (battery level, temperature, bitrate) are monitored independently but can be triggered collectively. This allows the device to implement complex multi-parameter monitoring without overwhelming processing overhead, as each parameter can be evaluated separately against its own threshold.
Solution Approach 2:
The patent implements partial monitoring by allowing the network to selectively enable or disable specific reporting triggers based on current service requirements. Not all parameters need to be monitored at all times - the system can activate only the necessary subset of monitoring parameters, reducing processing overhead while maintaining accuracy when needed.
3Productivity
If PCC rules and QoS settings are updated dynamically based on power status reports, then service delivery optimization is improved, but network control complexity increases
Solution Approach 1:
The patent establishes a feedback loop where power status reports from the device trigger automatic updates to PCC rules and QoS settings in the network. This closed-loop system allows dynamic service optimization based on real-time power status without requiring complex manual control, as the feedback mechanism automatically adjusts parameters based on predefined policies.
Solution Approach 2:
The patent enables the network system to self-adjust PCC rules and QoS settings based on received power status reports, without requiring complex external control. The automated policy execution and rule updates allow the system to optimize service delivery independently, reducing the need for complex network control intervention.

AI summary
A network device may receive a message that indicates an identifier of a wireless transmit/receive unit (WTRU) and/or one or more parameters associated with a power status of the WTRU. The network device may generate a power reporting policy, for example, based on the received message. The power reporting policy may include one or more triggers associated with sending a power status report. The network device may send the power reporting policy to the WTRU. The network device may receive the power status report from the WTRU in accordance with the power reporting policy. The power status report may include one or more battery characteristics associated with the WTRU. The network device may update one or more policy charging and control (PCC) rules based on the power status report.
