Engineering Contradiction Analysis
1Productivity
If different frequencies are selected for UMTS and LTE systems, then data transmission can be performed, but spectrum resources become unbalanced leading to shortage or waste
Solution Approach 1:
The patent merges UMTS and LTE systems to share the same frequency resource. The network side device allocates the shared frequency to either UMTS or LTE based on load information, combining two separate systems into a unified resource-sharing framework that eliminates spectrum imbalance.
Solution Approach 2:
The patent implements dynamic frequency allocation where the network side device continuously monitors load information of both UMTS and LTE systems and adjusts time slice allocation accordingly. This dynamic adjustment ensures that spectrum resources are allocated according to actual demand, preventing both shortage and waste.
2Loss of energy
If a shared frequency is allocated to both UMTS and LTE systems, then spectrum resource balance is improved, but system complexity increases due to load monitoring and time slice management
Solution Approach 1:
The patent segments the shared frequency resource into distinct time slices for UMTS and LTE systems. The network side device divides time into first time slices allocated to UMTS and second time slices allocated to LTE, managing complexity through temporal segmentation rather than simultaneous multi-frequency management.
Solution Approach 2:
The patent implements a feedback mechanism where the network side device monitors load information from both UMTS and LTE systems and uses this feedback to dynamically adjust time slice allocation. This closed-loop control simplifies decision-making by relying on automated feedback rather than complex manual configuration.
3Productivity
If time slice allocation is implemented based on load information, then data transmission efficiency is improved, but measurement and control difficulty increases
Solution Approach 1:
The patent enables the UMTS and LTE systems to self-report their load information to the network side device. Each system autonomously measures its own load state and transmits this information for allocation decisions, eliminating the need for complex external monitoring infrastructure.
