Cloud LAN Fronthaul Interface Selection for Option 2 and 3-1
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently establishing a fronthaul interface between network entities in a 5G or pre-5G communication system, particularly when different function split schemes are employed by various vendors, leading to difficulties in configuring a unified connection.
Innovation Solution
A communication node with a transceiver and controller is used to transmit and receive signals, enabling the setup of a fronthaul interface by dynamically selecting a function split scheme based on network conditions and service requirements, supporting both Option 2 and Option 3-1 configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different function split schemes are used by various vendors, then device complexity and adaptability increase, but interface configuration difficulty and reliability decrease
Solution Approach 1:
The patent applies parameter changes by dynamically selecting function split schemes (Option 2 or Option 3-1) based on network conditions and service requirements. The system changes the operational parameters of the fronthaul interface configuration rather than maintaining a fixed configuration, allowing adaptation to different vendor implementations while managing complexity through conditional selection rather than universal support for all variants.
2Adaptability or versatility
If function split scheme is dynamically selected, then adaptability improves, but control complexity increases
Solution Approach 1:
The patent implements dynamics by making the function split scheme selection dynamic rather than static. The controller dynamically chooses between Option 2 and Option 3-1 based on real-time network conditions and service requirements. This dynamic approach improves adaptability while managing control complexity through rule-based decision logic rather than manual configuration of multiple static options.
Solution Approach 2:
The system applies self-service by enabling the controller to automatically select appropriate function split schemes based on predefined criteria for network conditions and service requirements. This automated self-configuration reduces the need for manual intervention and complex external control, allowing the system to adapt itself to different operational contexts.
3Ease of operation
If unified fronthaul interface configuration is implemented, then ease of operation improves, but adaptability to different vendor schemes decreases
Solution Approach 1:
The patent applies universality by designing a fronthaul interface configuration method that can handle multiple function split schemes (Option 2 and Option 3-1) through a unified procedural framework. The same basic configuration steps accommodate different vendor-specific schemes by dynamically selecting the appropriate split option, making the system universally applicable across different implementations while maintaining ease of operation through standardized procedures.
