5G Distributed Antenna System Private Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G distributed antenna systems (DAS) do not effectively account for the distribution of baseband signals, leading to poor service level requirements (SLRs) performance, especially in 5G private networks that rely on multi-operator, multi-band DAS for coverage, where insufficient control over DAS components results in unmet latency and throughput guarantees.
Innovation Solution
A method and system for supporting private networks in DAS by determining activation and connection, identifying impacted paths, receiving resource and capability information, dedicating resources based on requirements, and utilizing these resources for traffic with specific identifiers, ensuring guaranteed quality of service (QoS) and service level agreements (SLAs) through network slicing and resource orchestration.

Engineering Contradiction Analysis
1Area of stationary object
If 5G private networks rely on multi-operator, multi-band DAS for coverage, then coverage area is improved, but control over DAS components is insufficient leading to unmet latency and throughput guarantees
Solution Approach 1:
The patent segments the DAS resource allocation by identifying and isolating specific paths impacted by the private network. The system divides DAS resources into private network dedicated resources and public network resources, enabling independent management and control of private network traffic paths within the multi-operator DAS infrastructure.
Solution Approach 2:
The patent applies local quality by dedicating specific resources along identified paths to private network traffic. Instead of uniform resource allocation, the system provides enhanced control and guaranteed quality of service parameters (latency, throughput) specifically for private network paths while maintaining multi-operator functionality elsewhere in the DAS.
2Reliability
If resources of DAS are dedicated to private network based on requirements, then QoS guarantees are improved, but resource allocation complexity increases
Solution Approach 1:
The patent performs preliminary action by proactively identifying paths impacted by the private network before traffic demands arise. The system determines which DAS resources will be dedicated to private network traffic in advance, based on network topology and private network requirements, enabling automated resource reservation and simplifying real-time resource management.
Solution Approach 2:
The patent implements feedback mechanisms to monitor private network traffic requirements and DAS resource availability. The system continuously evaluates whether dedicated resources are sufficient to meet private network QoS requirements and adjusts resource allocation accordingly, enabling dynamic optimization while maintaining service level agreements.
