Capillary Network Gateway Selection Using QoS Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanisms for selecting a capillary network gateway in scenarios where machine devices have access to multiple gateways lack efficient control mechanisms, leading to unnecessary delays for critical applications and inefficient resource utilization in cellular networks.
Innovation Solution
A method that allows for the selection of a capillary network gateway based on additional information, including Quality of Service (QoS) parameters of the backhaul connection, enabling operators to steer machine devices to gateways with appropriate QoS, thereby reducing the need for multiple bearers with different QoS at each gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine devices use channel quality measure or link metric for gateway selection, then the selection process is simple, but critical applications experience unnecessary delays due to lack of QoS consideration
Solution Approach 1:
The patent changes the selection parameter from basic channel quality metrics to comprehensive QoS parameters including data rate, latency, and reliability. The network node determines QoS parameters for multiple gateways and provides this information to the machine device, enabling QoS-aware gateway selection that accommodates critical applications while maintaining a manageable selection process through network-controlled parameter provision.
2Reliability
If multiple bearers with different QoS are established at each capillary network gateway, then service quality for different applications is improved, but network cost and complexity increase
Solution Approach 1:
The patent applies preliminary action by determining QoS parameters for all available gateways before the machine device makes its selection. The network node pre-calculates and provides QoS information (data rate, latency, reliability) for multiple gateways, enabling the device to select the most appropriate gateway in advance without requiring complex multi-bearer configurations at the gateway level. This prevents the need for establishing multiple bearers with different QoS at each gateway.
3Productivity
If machine devices autonomously select gateways without network control, then device autonomy is maintained, but resource utilization efficiency in cellular network decreases
Solution Approach 1:
The patent implements feedback by having the network node determine QoS parameters for multiple gateways and provide this information back to the machine device. The device uses this network-provided QoS feedback to make an informed gateway selection that optimizes resource utilization. This feedback mechanism maintains device autonomy in the final selection decision while ensuring network-aware resource efficiency through controlled information provision.
