5G Network Slice Packet Handling Without Cross-Domain Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G network systems face complexity in collaborative scheduling and inefficient deployment across multi-domain networks due to the need for cross-domain schedulers to process network slices, which complicates end-to-end system services.
Innovation Solution
A method for information processing that involves acquiring slice service information from a terminal device and sending an uplink slice service packet with a network slice identifier and parameter to a bearer network device, allowing the device to process the packet independently based on these identifiers and parameters, eliminating the need for complex cross-domain schedulers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-domain schedulers are used to achieve collaborative scheduling of end-to-end system services between base station and bearer network, then service coordination capability is improved, but system complexity increases
Solution Approach 1:
The patent segments the network into independent domains (base station domain, bearer network domain, core network domain), each with its own scheduler that operates autonomously. The base station scheduler handles radio resource allocation, the bearer network scheduler handles transport network resource allocation, and the core network scheduler handles session management. This segmentation eliminates the need for complex cross-domain schedulers while maintaining service coordination through standardized interfaces and signaling protocols.
2Adaptability or versatility
If cross-domain schedulers are deployed to enable collaborative scheduling, then end-to-end service processing capability is improved, but deployment efficiency deteriorates
Solution Approach 1:
The patent divides the scheduling function into separate domain-specific schedulers that can be independently deployed and managed. Each scheduler is deployed within its respective domain boundary, allowing parallel deployment and independent optimization. This segmentation enables faster deployment as each domain can be configured and activated separately without requiring coordinated deployment of a unified cross-domain scheduler across the entire network.
Solution Approach 2:
Each domain's scheduler is designed to be self-sufficient, making scheduling decisions based on local network conditions and service requirements. The base station scheduler autonomously manages radio resources, the bearer network scheduler independently allocates transport resources, and the core network scheduler self-manages session configurations. This self-service capability eliminates the need for complex inter-domain communication and coordination mechanisms, thereby improving deployment efficiency.
3Adaptability or versatility
If network slices are identified and processed individually in each domain, then network slice management flexibility is improved, but information consistency across domains deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where each domain's scheduler reports scheduling decisions, resource allocation status, and service quality metrics to a centralized network slice management function. The management function consolidates this information, maintains a unified view of network slice status across all domains, and provides feedback for coordination when necessary. This feedback loop ensures information consistency while preserving the flexibility of domain-specific scheduling operations.
Solution Approach 2:
The patent employs a universal network slice management function that operates across all domains, providing standardized interfaces and protocols for slice identification, registration, and status reporting. This universal management layer maintains a consolidated database of network slice configurations and states, ensuring information consistency across base station, bearer network, and core network domains while allowing each domain to manage its resources flexibly according to local requirements.
