Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G cellular technology struggles to meet diverse requirements for bandwidth, throughput, and reliability across various application scenarios, leading to inefficient radio resource utilization and increased power consumption in smartphones that need to manage multiple network slices for eMBB, mMTC, and URLLC scenarios.
Innovation Solution
A mobile communication device with a wireless transceiver and controller manages network slicing configuration by inquiring current configurations, determining if they meet application requirements, and reconfiguring as necessary, including downgrading parameters to ensure successful configuration and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smartphone requests multiple network slices (eMBB, mMTC, URLLC) to support diverse applications, then application diversity and service capability are improved, but radio resource utilization efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent applies universality by enabling a single network slice to serve multiple application types. Instead of requiring separate network slices for eMBB, mMTC, and URLLC applications, the system configures one network slice that can dynamically accommodate different application requirements, thereby improving radio resource utilization while maintaining support for diverse applications.
2Adaptability or versatility
If a smartphone requests multiple network slices (eMBB, mMTC, URLLC) to support diverse applications, then application diversity and service capability are improved, but power consumption increases
Solution Approach 1:
The patent reduces power consumption by eliminating the need for multiple network slice management operations. By using a single network slice that can dynamically adapt to different application requirements, the smartphone reduces the signaling overhead and processing required for managing multiple slices, thereby lowering power consumption while maintaining support for diverse applications.
3Adaptability or versatility
If network slicing configuration is reconfigured frequently to meet changing application demands, then service quality and adaptability are improved, but system complexity and configuration overhead increase
Solution Approach 1:
The patent applies dynamics by implementing dynamic service mapping that allows a single network slice to adapt its behavior based on real-time application demands. The system dynamically maps different application types to the same network slice resource, enabling service quality optimization without requiring frequent reconfiguration of network slice parameters, thus reducing configuration management complexity.

AI summary
A mobile communication device (110) including a wireless transceiver (10), a storage device (30), and a controller (20) is provided. The wireless transceiver (10) performs wireless transmission and reception using a Radio Access Technology, RAT. The storage device (30) stores program code of a management program. The controller (20) loads and executes the management program in an application framework layer to perform management of network slicing configuration, including: inquiring of the wireless transceiver (10) about first network slicing configuration that is currently applied in the wireless transceiver (10); in response to an application being activated, determining whether the first network slicing configuration meets one or more requirement parameters of the application; and in response to the first network slicing configuration meeting the requirement parameters of the application, sending a first configuration success message to the application without requesting the wireless transceiver (10) to reconfigure the first network slicing configuration.
