Network Slice Update Messaging for Reliable Device Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks fail to efficiently deploy and inform wireless communication devices of new network slices, especially when devices do not perform frequent network registrations or roam, leading to unused network slices and inefficient slice information updates.
Innovation Solution
A method involving the detection of wireless network slice information modifications, followed by the transfer of slice information modification messages to the device, with retries upon failure, ensuring successful update of slice information even in cases of initial message failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network slice information is updated only during network registration, then network registration procedures remain simple, but new network slices are not efficiently deployed to devices that do not perform frequent registrations
Solution Approach 1:
The system proactively pushes slice information modification messages to devices before devices need to request them, ensuring devices receive updated slice information without requiring frequent registrations. The network detects modifications and initiates push notifications to keep device information current.
Solution Approach 2:
The system implements acknowledgment mechanisms where devices confirm receipt of push messages, and the network tracks delivery status. This feedback loop ensures reliable information delivery and allows the system to handle cases where initial push messages fail to reach devices.
2Reliability
If slice information modification messages are sent immediately upon modification detection, then information freshness is maximized, but message delivery failures occur when devices are temporarily unavailable
Solution Approach 1:
The system implements retry mechanisms with backoff strategies to cushion against temporary delivery failures. When a push message fails, the system schedules retransmissions at later times, increasing the probability of successful delivery without immediately repeating the failed transmission.
Solution Approach 2:
The system employs periodic retry attempts for failed message deliveries, systematically resending push messages at intervals until acknowledgment is received or a maximum retry threshold is reached, balancing persistence with resource conservation.
3Loss of information
If devices perform frequent network registrations to receive slice updates, then slice information completeness is improved, but network signaling overhead and device power consumption increase
Solution Approach 1:
The network autonomously manages slice information distribution by detecting modifications and pushing updates to devices without requiring devices to initiate registration requests. This self-service approach eliminates the need for devices to frequently wake and register, reducing their power consumption while maintaining information completeness.
Solution Approach 2:
The network proactively pushes slice information updates to devices before devices would need to request them through registration, ensuring devices have current information without requiring active participation in registration procedures, thus reducing device energy usage.
4Stability of the object's composition
If slice information is pushed to all devices upon modification, then information consistency across the network is improved, but network signaling load increases
Solution Approach 1:
The system tailors push message delivery to individual device contexts, sending updates only to devices that need them based on their subscription information, device state, and current network conditions. This selective approach maintains information consistency for relevant devices while avoiding unnecessary signaling to devices that don't require updates.
Solution Approach 2:
The network segments the device population into groups based on their slice subscription profiles and delivery requirements, enabling targeted push message distribution. This segmentation allows the system to maintain consistency within relevant device groups while reducing overall network signaling load by excluding devices that don't need updates.
