Umbrella SIB Paging Message for System Information Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile telecommunications systems face inefficiencies in delivering system information to user equipment, particularly during handovers and in scenarios involving mobility and the integration of new services, especially for IoT devices and UAVs, where traditional methods are inflexible and lack forward compatibility.
Innovation Solution
The introduction of an 'umbrella SIB' system information block, which allows for the network to proactively push system information to user equipment through paging messages, enabling dynamic service activation and deactivation, and supporting new services by broadcasting timing and validity duration information, even in RRC inactive states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional system information delivery methods are used, then existing services are supported, but new services and future services cannot be efficiently delivered
Solution Approach 1:
The patent introduces an umbrella SIB that can serve multiple functions: it can deliver system information for existing services, new services, and future services through a single unified structure. This multi-functional approach eliminates the need for separate SIBs for each service type, thereby improving delivery efficiency while maintaining broad service compatibility.
Solution Approach 2:
The network can proactively push system information to user equipment before the UE actually needs it, using the umbrella SIB delivered via paging messages. This preliminary delivery approach prepares the UE in advance for upcoming services or handovers, improving efficiency by avoiding reactive information retrieval and reducing latency.
2Use of energy by moving object
If system information is delivered only when requested by user equipment, then network resources are conserved, but responsiveness to mobility and service changes is slow
Solution Approach 1:
The patent implements a feedback mechanism where the network monitors UE states (such as RRC inactive state transitions, mobility events, or service activation needs) and triggers proactive system information delivery through paging messages when specific conditions are met. This feedback-driven approach balances resource conservation with timely information delivery, as the network only pushes information when actually needed based on real-time UE status.
Solution Approach 2:
The network proactively delivers system information before the UE requests it, based on anticipated needs such as upcoming handovers, service activations, or mobility events. This preliminary action reduces the time delay between when information is needed and when it is delivered, while still maintaining resource efficiency by triggering deliveries only based on specific network-determined conditions.
3Speed
If dedicated signaling is used to push system information, then delivery speed is improved, but complexity of signaling increases
Solution Approach 1:
The patent uses paging messages as an intermediary mechanism to deliver system information. Instead of establishing complex dedicated signaling connections, the network embeds system information delivery triggers and parameters within standard paging messages. This intermediary approach maintains fast delivery speeds while avoiding the complexity of dedicated signaling protocols, as paging is a simpler, more standardized message type already supported by the network infrastructure.
4Adaptability or versatility
If multiple separate system information blocks are used for different services, then service specificity is maintained, but overall message size and processing overhead increase
Solution Approach 1:
The patent merges multiple service-specific system information blocks into a single umbrella SIB structure. This unified block contains organized information for existing services, new services, and future services, reducing the total volume of system information that needs to be transmitted and processed. The merging maintains service specificity through structured organization within the umbrella SIB, allowing UEs to efficiently extract only the relevant service information they need.
