Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network system uses fixed LCID range configuration in outdated architecture, then protocol compatibility is maintained, but adaptability to new cellular technologies (5G) deteriorates
Solution Approach 1:
The patent implements dynamic LCID range configuration where the network can switch between different LCID ranges (first range for legacy 4G/LTE devices, second range for 5G devices) based on device type and network conditions. This dynamic adaptation allows the system to accommodate both outdated and new cellular technologies without requiring a complete protocol overhaul, thus improving adaptability while managing complexity through controlled flexibility.
Solution Approach 2:
The patent changes the LCID range parameter from a fixed value to a configurable parameter that can be dynamically adjusted. By introducing configurable LCID ranges with different information elements for different ranges, the system can modify the LCID allocation parameters to match different cellular technology generations, enabling seamless transition from 4G/LTE to 5G while maintaining protocol compatibility.
2Adaptability or versatility
If the network system extends LCID ranges to accommodate 5G devices, then support for new features improves, but compatibility with existing 4G/LTE devices deteriorates
Solution Approach 1:
The patent segments the LCID space into multiple distinct ranges: a first LCID range configured for 4G/LTE devices and a second LCID range configured for 5G devices. Each range has its own information element configuration. This segmentation allows the network to independently manage and optimize LCID allocation for different technology generations, ensuring that new 5G features can be supported in the second range without disrupting compatibility with existing 4G/LTE devices using the first range.
Solution Approach 2:
The patent creates a universal protocol structure that can handle multiple LCID ranges and different cellular technology generations through a unified information element framework. The same protocol mechanism can accommodate both legacy 4G/LTE devices and new 5G devices by dynamically selecting appropriate LCID ranges, making the system multi-functional and technology-agnostic while maintaining reliable communication across all device types.
3Productivity
If dynamic LCID range switching is implemented, then network throughput and flexibility improve, but protocol processing complexity increases
Solution Approach 1:
The patent performs preliminary configuration of multiple LCID ranges and their corresponding information elements in advance, before actual data transmission. The network pre-establishes the first LCID range for 4G/LTE and the second LCID range for 5G, along with their respective parameter configurations. This preliminary setup allows for rapid switching between ranges during operation without requiring complex real-time calculations, thus improving network throughput while keeping protocol processing complexity manageable through pre-computed configurations.
