Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in efficiently managing the growing capacity and diverse traffic demands due to the rigid scheduling of Quality of Service (QoS) bearers across different network slices, which can negatively impact user experience and resource utilization.
Innovation Solution
The network node initiates a transmission of an indication during connection setup to the radio network node, specifying the supported set of functionalities within a network slice, allowing for differentiated resource scheduling based on the slice type, enabling flexible communication and improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rigid scheduling of QoS bearers is applied across all network slices, then implementation simplicity is maintained, but resource utilization efficiency deteriorates and user experience worsens
Solution Approach 1:
The patent segments the network slice functionality by introducing a specific indication parameter that identifies the network slice type. This allows the radio network node to differentiate between various network slice requirements and apply customized scheduling strategies for each slice type, rather than using a uniform scheduling approach for all slices.
Solution Approach 2:
The patent implements dynamic scheduling by enabling the radio network node to adjust scheduling parameters based on the received network slice indication. The scheduling behavior changes dynamically according to the specific network slice type, allowing optimization for different service requirements while maintaining a unified base scheduling framework.
2Device complexity
If uniform QoS bearer scheduling is used across different network slices, then system complexity is reduced, but adaptability to different service requirements deteriorates
Solution Approach 1:
The patent applies preliminary action by having the network node transmit the network slice indication parameter during the connection setup phase. This allows the radio network node to be pre-informed about the specific network slice type before actual data transmission begins, enabling proactive optimization of scheduling parameters without adding complexity to the ongoing communication process.
Solution Approach 2:
The patent utilizes parameter changes by introducing a specific indication parameter that carries network slice type information. This parameter enables the radio network node to modify its scheduling behavior according to different network slice requirements, achieving adaptability through controlled parameter variation rather than structural complexity.
3Productivity
If differentiated resource scheduling is implemented for different network slices, then resource utilization efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent merges the network slice indication with existing signaling messages by transmitting the indication parameter during the connection setup process. This approach combines multiple functions (connection establishment and network slice identification) into a single signaling exchange, avoiding additional separate signaling messages and minimizing overhead while enabling differentiated scheduling.
