Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HSDPA technologies lack specific solutions for implementing license control on base stations, which is essential for managing equipment processing capability and optimizing network resources according to varying demands.
Innovation Solution
A method and base station design that control the license by managing the number of HSDPA users, HS-PDSCH license codes, modulation mode, and throughput, allowing for dynamic adjustment based on network requirements, including determining the 16-QAM modulation mode if license requirements are met, to optimize network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If equipment processing capability is increased to meet growing service demands, then network service capability is improved, but equipment investment cost increases
Solution Approach 1:
The patent implements dynamic license control that allows base stations to adjust HSDPA processing capability in real-time based on actual network conditions and service demands. The system can dynamically activate or deactivate HSDPA functionality and adjust the number of supported users, enabling equipment to adapt its processing capability rather than requiring fixed over-provisioning for peak demands
Solution Approach 2:
The patent changes key operational parameters including the number of HSDPA users, modulation mode (QPSK/16QAM), and throughput limits based on license status and network conditions. By controlling these parameters, the system optimizes processing capability utilization without requiring permanent hardware upgrades, thus reducing unnecessary equipment investment
2Adaptability or versatility
If HSDPA processing capability is activated early to meet future demands, then future service capability is improved, but early stage investment cost increases
Solution Approach 1:
The patent implements preliminary license acquisition that reserves HSDPA processing capability for future use without requiring immediate activation. Network operators can obtain licenses in advance and activate them when service demands actually require them, preparing the system for future growth while avoiding premature investment in unused capacity
Solution Approach 2:
The system enables dynamic activation and deactivation of HSDPA capability based on actual network conditions. Processing capability can be turned on or off as needed, allowing operators to prepare for future demands without committing resources until they are actually needed
3Adaptability or versatility
If license control is implemented without specific protocol solutions, then equipment flexibility is maintained, but implementation complexity increases
Solution Approach 1:
The patent implements a universal license control mechanism that works across different equipment vendors and network configurations through standardized protocol elements. The solution uses common signaling procedures and parameter structures that can be applied universally in HSDPA networks, avoiding vendor-specific implementations and reducing overall system complexity
